Friends, good evening everyone. I'm Wang Chuanfu from BYD. Thank you for joining us. This is our third technology launch conference of the year. In 2025, we've started the year with technology, playing three consecutive technology cards, all of which are our trump cards. On February 10th, we launched the "Eye of God" intelligent driving system. On March 2nd, we launched the "Lingyuan" vehicle-mounted drone. These two technologies enhance users' intelligent travel experience. Today, we're bringing another major technology - the Super e-Platform, which will refresh the ultimate electric travel experience. The electric mobility experience drives the comprehensive evolution of electrification and intelligence.
As you saw in the video, we were among the first to make electric vehicles and understood them best. When the Chinese auto industry was still in its exploratory phase, engines, transmissions, and chassis—the three traditional elements of gas-powered vehicles—represented a technological gap difficult to overcome, holding back Chinese automakers for decades. When we began making electric vehicles, I proposed three new elements for EVs: batteries, motors, and electronic controls. And we had to firmly grasp these three elements ourselves. At that time, these three new EV elements were completely uncharted territory. Every technology requires our own breakthroughs.
I think in recent years, friends making EVs are quite fortunate. After more than a decade of development, China's EV supply chain has become the most complete, leading, and mature in the world. Now, the core components for making an electric vehicle can be purchased directly, unlike when we had to start from scratch. We had to rely on ourselves to pioneer everything step by step. Back then, our resources were very limited. When choosing the technical path for the three new elements, we couldn't afford any mistakes.
Batteries were our expertise. As early as 2002, we chose the lithium iron phosphate technology path. Initially, we knew absolutely nothing about motors. We recruited many electrical engineering professionals and conducted extensive comparative analyses. Finally, in 2004, we chose the permanent magnet synchronous motor technology. This type of motor proved to be the most suitable for electric vehicles. Regarding electronic controls, we recognized early on that IGBT power chips were the lifeline of electric vehicles. However, at that time, very few people had even heard of IGBTs. Globally, very few could make them. If we couldn't buy them, we'd make them ourselves. In 2005, we established our own chip team. In 2008, we acquired Ningbo Zhongwei Semiconductor. In less than a year, in 2009, we created our first IGBT chip.
Looking back now, when choosing our technological paths, we selected all the right future directions. At that time, there were no reference answers; we directly provided the standard answers. Thank you. Last year, lithium iron phosphate batteries exceeded 74% of vehicle installations, and permanent magnet synchronous motors reached over 95% adoption. IGBT power chips are now used in almost all electric vehicles. It's like solving high school exam questions while just starting middle school. The logic behind this is actually quite simple: we use technology to define our strategy. Technology allows us to see further and deeper.
After mastering the core technologies of the three electrical systems, we adopted a platform-based approach to vehicle manufacturing. In 2010, we launched e-platform 1.0, which was used in China's first mass-produced pure electric vehicle, the E6. We also created the industry's first 400-volt high-voltage architecture. We started with high voltage from the very beginning. Just one year later, in 2011, we registered the world's first 800-volt high-voltage architecture for commercial vehicles, which was first applied to the K9 electric bus. In 2015, we brought the 800-volt high-voltage architecture from commercial vehicles to passenger cars, installing it in the Qin EV. This was the world's first full 800-volt high-voltage architecture for passenger vehicles. It wasn't until 2019 that other passenger car brands developed 800-volt high-voltage systems, giving us a 4-5 year lead.
In 2018, we launched the e-platform 2.0, developing the three-in-one electric drive and high-voltage three-in-one system, achieving platform-based key vehicle systems. Leading the integrated development path for electric vehicles, in 2020 we launched a brand new model, the Han, marking a new era in our car manufacturing. The Han was equipped with many globally leading electrification technologies at the time, including the e-platform 2.0, the Blade Battery, a 16,000 rpm motor, and the world's first mass-produced silicon carbide module. Especially the Blade Battery, which completely eliminated concerns about battery safety, setting a new global standard for power battery safety. These technologies made the Han the new benchmark for Chinese electric vehicles of that era.
In 2021, we created the most professional pure electric platform ever, e-platform 3.0, featuring the world's first eight-in-one electric drive system. The following year, we developed the industry's first CTB (Cell-to-Body) integrated battery and body technology, applied to the Seal. This means we've truly achieved vehicle-level platform integration, redefining the electric vehicle platform and the spatial layout of electric vehicles. By 2024, we introduced e-platform 3.0, further integrating the world's first twelve-in-one electric drive system, creating a new foundation for intelligent electrification.
Looking back on our 15 years of technological innovation, we've taken one step at a time, always maintaining the pioneering spirit of our early years. We can proudly say that in electric vehicle technology innovation, each generation we release leads the industry. The development of electric vehicle technology has made tremendous leaps to date. However, in terms of charging, people still experience range anxiety. Everyone hopes that charging time can be shorter, or even shorter. People don't worry about gas cars because refueling is fast and convenient; it takes 5-8 minutes to refuel and leave the gas station. But charging takes at least half an hour or more before leaving the station, and sometimes there are queues at charging stations. So improving charging speed and reducing charging and waiting time is essential to solving charging anxiety.
To completely eliminate users' charging anxiety, our goal is to make electric vehicle charging time as short as refueling a gas car – achieving the same replenishment speed for both electric and gas. To achieve this, we must develop ultra-high power charging, meaning we need both ultra-high voltage and ultra-high current to maximize charging speed. For ultra-high voltage, we achieved a full 800-volt high-voltage architecture ten years ago; today, we're challenging even higher voltages. Directly pushing the voltage to 1,000 volts. Upgrading the battery, motor, power supply, air conditioning, and all components to 1,000 volts. Becoming the world's first mass-produced passenger car with a full 1,000-volt high-voltage architecture. Our charging voltage will also reach 1,000 volts. The highest in mass production globally. We've already achieved ultra-high voltage. Next, we need to tackle ultra-high current.
To achieve ultra-high current, we need to reduce battery internal resistance. Increase lithium-ion migration speed. We've made many innovations in batteries. For example, lithium-ion movement from the cathode to the separator and then into the anode. We've built ultra-high-speed ion channels in all aspects, like paving a wide and straight highway for them. We reduced the internal resistance by 50%, allowing lithium ions to move faster without congestion. Ultimately, we've achieved a greater charging current, making a huge leap in our charging current. Now, the industry's maximum charging current is 700 amperes. This time, we've directly increased it to 1,000 amperes. The highest in mass production globally: 1,000 ampere ultra-high current. 1,000 ampere current gives our battery the highest charging rate in mass production globally: 10C. Thank you.
So how do we understand the charging rate? It's like watching TV shows on your phone; everyone likes to use 2x or 3x speed. The industry's highest is currently 6C, which is like watching at 6x speed. Our 10C is equivalent to watching at 10x speed. With a charging voltage of 1,000 volts and a charging current of 1,000 amperes, our battery's charging power reaches 1,000 kilowatts, or one megawatt, the highest in mass production globally. This is the industry's first achievement of the megawatt unit in charging power. Let's witness together at this moment: Electric vehicle charging power officially enters the megawatt era.
Megawatt-level charging power—we feel that terms like fast charging or super charging are no longer sufficient to describe it. Our engineers suggested we need a higher level to define it; it should be called "Megawatt Flash Charging." The threshold for flash charging is megawatt-level charging power. No megawatt, no flash charging. Our newly upgraded battery focuses on charging speed. It can achieve megawatt flash charging. This is our flash charging battery. I believe the media friends present here witnessed the flash charging speed at our outdoor venue this afternoon. For those who saw it on-site, do you think this charging speed is fast enough? Fast! Here, I'll show a video of an actual charging test to our friends present. Let's see just how fast it is.
Everyone has seen the extreme speed of our megawatt flash charging. 20 kilometers charged in 10 seconds, that's 2 kilometers per second. The highest peak charging speed in mass production globally. If we look at a longer time frame, say, 5 minutes... The industry's fastest charging currently provides 255 kilometers of range in 5 minutes. But with our megawatt flash charging, can you guess how much range can be added in 5 minutes? We also conducted a 5-minute charging test. To save everyone's time, we sped up the video 10 times. Let's take a look at how much range can be charged in 5 minutes. Watch the video.
This is the world's fastest charging speed. 5 minutes of flash charging provides 400 kilometers of range. This video was played at 10x speed. We'll post the original 5-minute video (without acceleration) on our official platforms later. Please stay tuned. As I mentioned earlier, it takes 5-8 minutes to fill up a gas car, giving it a range of approximately 500 kilometers. Now, with our megawatt flash charging, we can add the same range in just 5-8 minutes, finally achieving charging speeds as fast as refueling times. This officially ushered in the era of oil-electric parity, changing charging from "people waiting for cars" to "cars waiting for people."
Of course, with megawatt-capable cars, we also need megawatt charging stations. This time, we have also developed megawatt flash charging station technology. The output power of our flash charging stations also reaches 1 megawatt. We plan to build over 4,000 megawatt flash charging stations nationwide. In addition to building our own stations, we have also decided to fully share BYD's megawatt flash charging station technology with the industry. We welcome more social capital to participate and jointly promote the construction of megawatt-level charging facilities.
In addition to accelerating the construction of flash charging stations, we also want to maximize the use of existing charging resources in the market to make charging more convenient for users. There are now many supercharging stations across the country, such as Huawei's liquid-cooled supercharging stations. The charging station has a power output of 600 kilowatts. Using our dual-gun charging technology, plugging in two guns simultaneously transforms it into a 1-megawatt supercharging station, instantly turning supercharging stations into flash charging stations.
Additionally, we have a massive foundation consisting of millions of public charging stations nationwide. From the earliest 500 volts, to the later 750 volts, and now 1,000 volts, for these stations, we have intelligent voltage boosting technology. Using only existing motors and electronic controls in the vehicle, without adding new components, we can achieve voltage-boosted fast charging. Achieving full compatibility with public fast charging stations, and enabling charging at all of them. Moreover, at these public charging stations, we can also achieve very fast charging. For example, using dual-gun charging at a 250-kilowatt public charging station, we can achieve a charging power of 500 kilowatts, higher than many supercharging stations. Turning public fast charging stations into supercharging stations, our charging technology system truly enables charging at any station, allowing our users to enjoy the ultimate charging experience anytime, anywhere.
This is our megawatt flash charging, solving the two major issues of charging anxiety: slow charging or inconvenient charging. Slow charging and inconvenient charging have both been resolved, completely eliminating users' charging anxiety for electric travel. Of course, besides the flash charging battery, we've also comprehensively upgraded the core motor and electronic control systems. We've developed a brand new high-speed motor with a speed of up to 30,511 RPM, the highest in mass production globally. It's the industry's first mass-produced 30,000 RPM motor. How powerful is the performance of this 30,000 RPM motor? We've achieved a single-module, single-motor power of 580 kilowatts, the highest in mass production globally. One motor surpasses the performance of two motors, completely outperforming a V12 engine. It's truly a performance beast.
Our high-speed motor isn't just about speed; we have our own understanding: making the motor smaller and lighter. This powerful performance combined with a lightweight design allows the 30,000 RPM motor to achieve a power density of 16.4 kilowatts per kilogram, also the highest in mass production globally. Such a compact motor adds 20 liters of space to the Han L's trunk, enough to fit an extra carry-on suitcase. With such a powerful motor, conventional power chips can hardly handle it. We've developed and mass-produced a new generation of silicon carbide power modules to match its ultra-high power. It has a voltage rating of 1,500 volts, also the highest in mass production globally. Since 2005, when we established our chip team, we've been working on chips for 20 years. From chip design, wafer manufacturing to module packaging, testing, and application, we've achieved in-house research and production for the entire chain. In 2009, we produced our first first-generation IGBT chip. The IGBT chip also passed the national scientific and technological achievement appraisal. To this day, our core three-electric technology continues to innovate, yielding fruitful results and winning multiple National Science and Technology Progress Awards.
26 years ago, we proposed to firmly grasp the three new components of electric vehicles. Now, we can proudly say that our engineers have achieved this. This is our super e-platform. It features megawatt flash charging, a 30,000 RPM motor, and a new generation of silicon carbide power modules. It enables the comprehensive evolution of electric vehicles, setting multiple global records and redefining electric vehicles, leading the next era of electric vehicles. With such a powerful super platform, think about it. Do you want to own it right away? This time, the super e-platform will debut on the Han L and Tang L. Launched and mass-produced simultaneously, equipped immediately. Later, we'll unveil them on-site. This marks another significant chapter in the 100-year history of Chinese automobiles. A brilliant chapter in the century-long history of cars.
Today, a new energy vehicle rolls off the production line in China every 3 seconds. One is exported every 16 seconds. We are progressing from a major automobile country to a strong automobile power. Becoming a global leader in electric vehicle technology. Today's achievements are the result of all Chinese brands racing with technology. Chasing and surpassing each other, setting new records time and time again. We're like sprinting with innovation in a determined race. Today, we've taken up the baton for pure electric vehicles once again. We also look forward to the future, seeing more Chinese brands take up this baton. Together, passing it on one by one. Pushing Chinese electric vehicle technology to greater heights; Thriving through competition; The journey of the new era; New productive forces have broad prospects; It's time for Chinese automobiles to shine; Let's bravely ride the wave; Create the future; And surge forward; Thank you all.

Those milestone moments in the video will eventually crystallize into tonight's protagonist. Now, let's applaud. Please welcome Luo Hongbin, Senior Vice President of BYD Group and General Manager of the 14th Business Division, to take us through the details behind the 30,000 rpm motor. Please welcome.

Hong-bin Luo27:01
Distinguished guests, media friends. Good evening, everyone. Next, I will share with you the latest technological achievements of the 30,000 rpm electric drive assembly. Today, we are launching the world's first mass-produced 30,000 rpm electric drive assembly. This assembly boasts a motor power density of 16.4 kW/kg, leading globally. Motor speed has increased from 7,500 rpm in the first generation to 23,000 rpm in the fifth generation, continuously pushing speed limits. And now, we have achieved a milestone leap, successfully pushing motor speed to a new height of 30,000 rpm. Next, please enjoy a video of the motor rotating.
The 30,000 rpm motor rotor design. Facing the challenge of ultra-high centrifugal force, we fully committed ourselves to a battle of materials and technology. First, the rotor laminations use 1 GPa high-strength silicon steel, increasing the yield strength by 138% compared to ordinary silicon steel. This effectively withstands the enormous centrifugal force at 30,000 rpm. Second, the rotor core employs advanced bonding technology, significantly improving its axial stiffness by 161% compared to traditional riveting. This also effectively improves the motor's NVH (noise, vibration, and harshness). Vibration was effectively improved by more than 2 dB.
To effectively secure the magnets at 30,000 rpm, we independently developed a specialized magnet retention layer, increasing the fixing strength of the magnets by two times and firmly securing them in the magnet slots. Finally, we used aviation aluminum for the end plates to fix the rotor iron core, increasing its strength by 159% compared to the ADC 12 die-cast aluminum design. When the rotor runs at 30,000 rpm, the dynamic balance will generate 612 Newtons of centrifugal force, equivalent to the weight of a 62 kg adult. The weight of a 17 kg adult rotor severely affects the stability of the rotor during high-speed operation. The importance of high-speed dynamic balancing becomes apparent at this point. Therefore, our self-developed high-speed shaping machine can drive the rotor at 30,000 rpm, effectively removing internal stress generated during manufacturing, heat treatment, and assembly processes. We first pre-balance the 17 kg rotor to 100 mg at 1,500 rpm, then balance it to 50 mg after high-speed shaping at 30,000 rpm. What does 50 mg mean? It's approximately the weight of a drop of water.
To achieve ultra-high performance in the motor, we adopted a new high-strength double-U structure for the rotor battery design. Compared to the traditional double-V structure, the number of reinforcement bases increased from 6 to 9. This not only increased the rotor strength by 17%, but also optimized stress distribution, making the rotor more stable and reliable during high-speed operation. Another significant advantage of the double-U topology design is the larger area for magnet arrangement, and the greater number of magnets. In a single stage, the number of magnets increased from 4 to 7. Significantly improving magnet concentration effect by optimizing magnetic field distribution. By concentrating more of the externally dispersed magnetic field internally, the rotor magnetic field strength is enhanced, ultimately increasing motor power by 15%.
To further increase power, N50EH high-performance magnets were used, offering 18% better magnetic performance compared to industry-standard magnets. Magnet segmentation technology reduced eddy current loss by 44%. Additionally, through stator-rotor magnetic circuit optimization design and adopting a rotor direct pole design scheme, concentrated leakage flux was further reduced, increasing motor power by 7%. To further increase motor power, a stator saturated magnetic field design scheme was adopted. The peak magnetic flux density was increased from 1.9 Tesla to 2.1 Tesla, thus maximizing the saturation characteristics of the magnet materials. This resulted in a 5% increase in motor power. Furthermore, an extra-large air gap design between the stator and rotor ensured a peak power of 580 kW at 14,000 rpm and a high power output of 524 kW at 30,000 rpm, guaranteeing continuous high power output in the high-speed range. This is at an advanced level in the industry.
High speeds can easily lead to high losses. The stator, as the main heat source... The stator is the main heat source. We suppressed its losses from the following two aspects: First, a custom iron core using 0.2 mm silicon steel sheets, combined with bonding, effectively reduced core loss by 17%. Through AI simulation, we found that the 6-pole, 72-slot, 10-layer short-pitch design scheme has the best overall performance. Compared to 6-layer, 8-layer, and 12-layer schemes, the 10-layer winding scheme has the lowest total copper loss, decreasing by 21% compared to the 6-layer scheme. The short-pitch design increased peak power by 11%. The 6-pole, 72-slot short-pitch main magnetic field design scheme comprehensively improved the positive rotation of the stator magnetic field, reducing NVH by 5 dB.
The Super e-platform adopts a kilovolt high-voltage architecture, which posed a significant challenge to our insulation system. To address this challenge, we independently developed a high-voltage paint film. Compared to traditional paint films, the dielectric constant decreased by 41%, the PDIV (Partial Discharge Inception Voltage) increased by 13%, the breakdown voltage increased by 8%, and the paint film thickness decreased by 15%. This completely solved the technical challenge of copper wire insulation for the 1,000-volt high-voltage platform stator, laying the foundation for our motor to achieve a high power density of 16.4 kW/kg.
A 30,000 rpm motor runs 500 revolutions per second. The mechanical cycle for one revolution is two milliseconds, and the electrical cycle is 666 microseconds. This means we must complete one full sampling, calculation, and output within 30 microseconds. To overcome this technical challenge, we adopted a 300MHz quad-core chip and introduced multi-core, multi-threaded parallel computing technology. Multi-layer parallel computing technology ensures precise power output. Through continuous optimization of the algorithm architecture and precise calibration of the hardware circuits, the current loop response time has been reduced to within 20 microseconds. Traditional resolver position sensors cannot adequately meet the precise requirements for rotor position at 30,000 RPM. Therefore, we independently developed an eddy current position sensor with a signal delay of less than 4 microseconds and a rotor position error of less than 10 minutes, achieving more than three times the accuracy of traditional resolver position sensors. Our electronic control system is 15,000 times faster than the human nervous system.
To ensure the motor maintains precise and efficient power output even at extreme speeds, a 1,000-volt platform is required. This necessitates a 1,500-volt half-bridge withstand voltage for the power module. To overcome this challenge, we independently developed a 1,500-volt silicon carbide power module. Utilizing a double-sided silver sintering process and high-temperature resistant packaging technology, the power module can withstand junction temperatures up to 200 degrees Celsius. A symmetrical wafer layout is employed, reducing stray inductance to 5nH. Furthermore, laser welding technology is used in the power circuit. Reducing the inductance of the power circuit ensures high power output of the electronic control system. Furthermore, based on vehicle big data, we developed an optimized control strategy. The power module output current reaches 1,000 amperes, achieving a perfect combination of high voltage and high current, fully unleashing the motor's performance.
The 1,000 volt platform presents tremendous challenges for electronic control safety design. We are dealing with 1,000 volts plus 30,000 RPM. Therefore, this safety design faces extreme challenges. For this reason, we specifically developed a 1,500-volt, 1,200-ampere energy source cutoff switch. To ensure safety at 30,000 RPM, we have specially developed a 1,500-volt, 1,200-ampere energy source cutoff switch. This switch actively disconnects the electrical connection between the motor and controller within two milliseconds. Simultaneously, we dynamically monitor over 20 critical variables, tracking every safety detail in real time.
To ensure stable output from high-speed motors, transmission design is crucial. Therefore, we have created a new high-speed parallel shaft transmission architecture using a 4-planetary differential, which provides 22% more torque than a 2-planetary differential and improves differential capability by 72%. 72% improved differential capability; 45% improved differential capability; a large 10.9 speed ratio; achieving a powerful wheel torque output of up to 5,500 Newton meters; ensuring reliable system operation at high speeds; when motor speed exceeds 30,000 RPM, gear line speed reaches 306 kilometers per hour; gears face risks of wear, insufficient adhesion, and other failures; to overcome this challenge, we employed precision machining processes, improving gear surface precision to grade four, with a gear surface error less than 1/20th the thickness of a human hair. The anti-seizing capability was improved by 42%, ensuring stable gear operation under high torque and high-speed conditions.
At 30,000 RPM, the bearing line speed reached 142 kilometers per hour, creating a high-speed rotating airflow internally, equivalent to a level 10 wind force. This presented unprecedented challenges for bearing lubrication design. Through multi-dimensional optimization of oil spray flow velocity and angle, compared to 20,000 RPM, heat exchange capability improved by 78%, and lubrication flow increased by 500%, successfully solving the bearing lubrication challenge.
To provide users with a more comfortable and quieter driving experience, we conducted multi-dimensional NVH optimization design. The motor achieved a 6dB reduction by lowering harmonic magnetic fields. The transmission system adopted a micron-level gear surface design to reduce transmission error, achieving a 6dB reduction. The electronic control system achieved a 6dB reduction through harmonic injection and full-spectrum noise reduction. Finally, the assembly near-field noise of only 20,000 RPM was reduced by 6dB(A). Through a series of technological innovations, we have created an exceptional electric drive assembly, suitable for both city and highway driving conditions. It can handle everything perfectly in high-speed scenarios, leading electric drive systems into the 3.0 era and helping to comprehensively improve vehicle power, efficiency, and comfort. Thank you everyone.

Next, please welcome Lian Yubo, Executive Vice President of BYD Group and Dean of the Automotive Engineering Research Institute, to share with us the technological prowess of the super e-platform.

Lian Yubo51:01
Good evening everyone. I am Lian Yubo from BYD. Next, I will share from the perspective of the whole vehicle and user needs the technological logic behind the revolutionary innovations of the super e-platform. 15 years ago, we launched China's first mass-produced pure electric vehicle, the E6. The mass-produced pure electric vehicle, the E6, and the first-generation pure electric dedicated platform, the e-platform, marked the beginning of China's automotive electrification journey. The e-platform continuously explored the limits of electrification through ongoing technological innovation. In 2010, the E6 broke through the range limit of pure electric vehicles. In 2020, the Blade Battery led a safety revolution, breaking through the upper limit of battery safety. In 2021, the e-platform 3.0 pioneered the world's first CTB (cell-to-body) integration technology, breaking through the boundaries of system integration design. Last year, we launched the latest e-platform 3.0 Evo. The latest e-platform 3.0 Evo has created a 12-in-1 intelligent electric drive system with the highest level of structural and integration breakthroughs. This breakthrough, pushing the boundaries of integrated innovation, aims to provide users with the ultimate driving experience.
Today, our pure electric vehicles not only completely surpass fuel vehicles in terms of safety, efficiency, and comfort, but also create entirely new experiences in intelligence, aesthetics, and space. As Mr. Wang just mentioned, making charging as fast as refueling, achieving EV-ICE parity, has become the ultimate expectation of users in the era of electrification. A few years ago, under Mr. Wang's leadership... Under Wang's leadership, our technical team, aiming at the ultimate goal of "EV-ICE parity," launched another extreme offensive. Today, the Super e-platform has delivered this answer. We are ushering in a new era of "EV-ICE parity" with four revolutionary technologies: We have created the world's first super kilovolt architecture for electric vehicles; the world's first flash-charging battery; and the world's first megawatt flash-charging system. Simultaneously, based on the kilovolt architecture, we have created the world's first mass-produced 30,000 rpm super electric drive system. This time… Thank you.
This time, we have broken through the voltage platform of electric vehicles, the upper limit of charging speed and motor speed. The super kilovolt architecture has brought the voltage platform of electric vehicles into the kilovolt era. Why do we need 1,000 volts? To achieve the goal of "EV-ICE parity," we have increased the charging power to the megawatt level. The kilovolt architecture is the foundation for achieving "megawatt flash charging" and "EV-ICE parity." We not only need to upgrade the power battery to 1,000 volts, but also need to redesign the drive system, charging and distribution system, electric air conditioning, etc. The drive system, charging and distribution system, electric air conditioning, and more have all been upgraded to 1,000 volts, creating the world's first full-range 1,000-volt high-voltage architecture for pure electric passenger vehicles. We even redesigned the distance between two bolts in the electronic control unit, as well as the insulating paint film on the motor's enameled wire. We rebuilt design standards for thousands of technical details across the vehicle's five major systems, especially the core power chip. One end is directly connected to the 1,000-volt DC battery, and the other end is connected to the drive motor. It needs to work as soon as the motor starts. Not only does it directly bear the 1,000-volt high voltage from the battery, but it also needs to withstand the voltage applied by various inductors in the circuit.

Especially as the switching frequency increases, the voltage released by the inductor becomes higher. Therefore, we specially developed a kilovolt architecture, the world's highest 1,500-volt automotive-grade silicon carbide power chip. This is far from enough. We even eliminated the connecting bolts between the power module and capacitors, directly welding them together with laser. This not only reduces the inductance in the circuit loop but also improves the current supply capability of the power chip. The 870 kV architecture represents a comprehensive upgrade to the electric vehicle design system. We not only overcame the challenges of electrical, magnetic, mechanical, and thermal coupling at 1,000 volts, but also overcame the difficulties of safety and EMC system design at high and low voltages. Furthermore, we reconstructed the kilovolt architecture design system from materials and components to the entire vehicle. What's even more challenging is that there was no industry supply chain for the kilovolt high-voltage architecture. Just like over 20 years ago when we first started making electric vehicles, as long as users have a need, we create whatever the industry lacks. Therefore, we not only designed the kilovolt architecture, but also, relying on BYD's comprehensive industrial layout, independently established the manufacturing capability for the entire industrial chain of the kilovolt architecture. Based on the kilovolt architecture, we created the world's first megawatt flash charging technology system. The vehicle's charging power reaches up to 1,000 kilowatts. This redefines the charging experience for electric vehicles. Why do we say it's redefining? Because we're talking about increasing the charging voltage, current, and power of electric vehicles by an order of magnitude. 1 kilovolt, 1 kiloamp. 1 kilovolt, 1 kiloamp, 1 megawatt. Each number is the highest in the world. Each number is pushing the limits of design. The power reflected in the data translates into user experience. As President Wang mentioned earlier, our flash charging allows for 400 kilometers of travel in 5 minutes. What does 400 kilometers mean? Let me give you some examples. 400 kilometers can take you from Beijing to Jinan, from Shanghai to Hefei, or from Guangzhou to Guilin. A 5-minute flash charge enables travel between three major cities. This speed has completely matched the refueling experience of gasoline vehicles. What do you all think? Is it fast? Such a short charging time is not only due to our kilovolt architecture, but also to our kilo-amp high current. Where does such a large current go? Of course, it goes into the battery. So we developed a flash-charging battery specifically for the Super e-platform. Speaking of charging, we must talk about the charging rate. Our flash-charging battery reaches a maximum charging rate of 10C. The charging rate has entered the double-digit era for the first time. What does such a high charging rate mean? It means that a large number of ions instantly detach from the cathode and pass through the electrolyte. Ions pass through the electrolyte, cross the separator, and finally migrate into the anode. Every checkpoint and channel the ions pass through must be unobstructed. For this, we redesigned the Blade Battery. Our engineers focused on one goal: to make ion transport in the electrolyte faster, to reduce the resistance when ions pass through the separator, and to make the path for ions entering the electrode more direct. All designs are aimed at creating a super-high-speed channel. Reducing the battery's internal resistance isn't enough with just innovations in electrolyte, separator, and electrodes. On the exterior of the cell, we redesigned the terminals. The terminals were redesigned, creating a dual electron flow channel for the Blade Battery. This broadened the high-speed highway for electron movement, reducing cell heat generation by 50%. We also innovated with ultra-stable self-repairing SEI film technology, achieving a 35% increase in high-temperature battery life. Flash-charging batteries require both high rate of charge and long lifespan. Here, I'd like to express my pride in our Blade Battery. Five years ago, we launched the Blade Battery, rewriting the history of electric vehicle safety. We also introduced battery-body integration technology based on the Blade Battery, leading a new direction in industry technological development. In industry technology development, we announce again today that the Blade Battery is not only the best carrier for safety, but also a natural partner for flash charging. The Blade Battery's symmetrical design and stacking process create the shortest heat transfer path, improving thermal conductivity by more than 5 times, making it especially suitable for maximum frequency charging. Of course, our advanced thermal management system also plays a significant role. In 2021, we introduced the world's first power battery with a 'smart-sensing' system. At that time, people might not have understood this technological approach. The industry's traditional cooling medium was mainly coolant. To remove more heat, a secondary heat exchange between refrigerant and coolant is necessary, resulting in low heat dissipation efficiency and insufficient cooling speed. Our thermal management system uses refrigerant for direct cooling, resulting in not only high heat transfer efficiency but also lower controllable temperature and faster heat dissipation. Today, cooling and heating technology has undergone another comprehensive evolution. We've pioneered a three-dimensional flow path composite temperature control system. The battery has refrigerant flow paths covering both the top and bottom, improving heat exchange performance by 90%. It can instantly dissipate the heat from megawatt flash charging. With such high heat exchange efficiency, the refrigerant weighs only one kilogram. For the same heat exchange requirements, if replaced with coolant, it would require 10 kilograms. Therefore, refrigerant cooling greatly reduces the weight of the cooling system. Furthermore, compared to coolant, refrigerant is completely non-conductive. No more worries about safety risks from battery cooling fluid leakage. Besides the megawatt flash charging capability, the super e-platform continues to excel in safety. The lithium iron phosphate battery system has inherent safety and natural advantages. The vehicle continues to use the high-safety CTB battery-body integration technology. Battery-vehicle integration technology: A powerful combination that enhances vehicle safety. Furthermore, we have comprehensively upgraded the battery pack's protection capabilities. The battery baseplate boasts 1,200 joules of protection, exceeding international requirements by 7 times in impact resistance. It also meets industry standards for energy efficiency, with a 400kN battery system compression rating four times the national standard. Flash-charging batteries easily pass these tests, ensuring both battery and vehicle safety. Now, I'd like everyone to watch a video.
Meanwhile, regarding electrical safety, we have achieved excellence not only in power systems, functional safety, charging safety, and battery safety, but also in vehicle-battery compatibility, high-voltage safety, and diffusion protection. Our Super e-platform models have received six-dimensional electrical safety certification from national authorities. Besides the vehicle and battery, megawatt flash charging also requires charging stations. As CEO Wang just mentioned, we will build over 4,000 megawatt flash charging stations. Our engineers have applied over 20 years of vehicle manufacturing experience to charging stations, creating the industry's first megawatt flash charging system. Completing the final link in the megawatt charging ecosystem: We've independently developed the world's first fully liquid-cooled megawatt flash charging system, achieving a maximum power of 1,360 kilowatts. Leveraging our 20+ years of rich experience in vehicle energy systems, the megawatt flash charging system achieves extremely high power density. Despite such high power, it occupies only 1.5 square meters of space—about the size of a dining table. To improve charging station utilization efficiency, we've equipped the megawatt flash chargers with two charging guns. With intelligent power distribution, in addition to the ultimate charging power, we also pay special attention to the user experience. To achieve extreme charging power, we also focus on user experience. With such high charging power, you might expect a heavy charging gun. However, our megawatt flash charging gun weighs only two kilograms. Our innovative ultra-light cool night liquid-cooled charging gun not only cools the cable but also enhances heat dissipation at the charging gun terminals. This weight is user-friendly for both male and female users. Effortless plugging makes flash charging easier. In fact, BYD began deploying charging stations over a decade ago. Therefore, we think more broadly and further ahead in the charging field, for example, in many older communities and urban villages. Insufficient power grid capacity restricts the widespread use of high-power charging stations. To address this, we have developed a dedicated energy storage system for megawatt flash charging, freeing it from grid capacity limitations. Our flash charging system can be enjoyed wherever there is electricity. Besides building charging stations, we are also considering how to enable everyone to experience megawatt flash charging at charging stations near their homes. Combining our innovations in charging technology over the past decade, the Super e-platform has created an all-scenario megawatt flash charging solution. As President Wang just mentioned, we not only transformed supercharging stations into flash charging stations through dual-gun charging technology, but also used the electric drive boost charging technology we innovated five years ago, enabling charging at any station. Furthermore, through intelligent pulse self-heating technology, we allow for rapid preheating and flash charging even in extremely cold temperatures. What are the benefits of implementing these technologies for our globally pioneering electric drive topology and deep reuse technology? Taking our electric drive boost charging as an example, by reusing the motor and electric control power devices for voltage boost, the charging power can theoretically be as large as the driving power. The charging power can theoretically be as high as the driving power without taking up extra space. The limited space in the vehicle is maximized for the user. This is also the original intention of our e-platform's inherited innovation. Look, at our four generations of e-platform displays outside, the components get smaller with each generation, the space gets larger with each generation, and the capabilities get stronger with each generation. With the super kilovolt architecture, flash charging batteries, and megawatt flash charging system, the super e-platform has built the world's first full-stack megawatt flash charging solution. We've established a complete megawatt flash charging technology system. We've achieved a closed loop for the megawatt flash charging ecosystem. Now that we've covered charging, let's look at our super electric drive. As mentioned earlier, our motors play a huge role in all-scenario flash charging. Their driving capabilities are even more formidable. As President Luo mentioned earlier, our drive motor's rotation speed is the highest in mass production globally. Our motor's power density is also the highest in mass production globally. We've achieved the world's highest single motor power of 580 kW in mass production with just a single power module. What does 580 kW mean? It's equivalent to the performance of a V12 engine. It's equivalent to the performance of a V12 engine. Our motor's volume is only 1/4 of its size. Our power is even greater, and the 0-60 mph acceleration is faster. Especially with the support of 1,000-volt voltage, the motor's high-end power has doubled. It's not just quick in 0-60 mph acceleration, but even stronger in 60-125 mph overtaking acceleration. So how strong is it exactly? I'd like to show you another video clip.
What do you think? Is it powerful? Our super e-platform vehicles achieve 0-60 mph acceleration in the 2-second range. The 60-125 mph overtaking acceleration is in the 4-second range. For top speed, our engineers reached over 185 mph with just one press of the accelerator. We had to limit it through software to bring it down to 185 mph. Moreover, our performance engineers also suggested that one press of the accelerator isn't enough; they want to do it several times. However, heat dissipation in the electric drive is a major issue. Our electric drive engineers weren't to be outdone; they proposed using refrigerant to cool the electric drive system. Using refrigerant to cool the electric drive system allows for precise temperature control, eliminating the anxiety of overheating during continuous rapid acceleration. Over 70 consecutive 0-60 mph accelerations show no performance degradation. Extreme performance remains consistent. This concludes the content of the Super e-platform. The world's first super kilovolt architecture, megawatt flash charging system, and 30,000 rpm super electric drive form the strongest foundation for BYD's new generation of electrification technology. Every number tells history, just as each generation of the e-platform writes a new legend of electrification. Each generation of the e-platform is writing a new legend in electrification. As mentioned earlier, these technological innovations of the Super e-platform all stem from previous e-platform generations. Ten years ago, it was 800 volts; today, it's megawatts. Today's evolution is to today's megawatt kilovolt architecture. Five years ago, the Blade Battery achieved 10C flash charging. Four years ago, direct refrigerant cooling laid a solid foundation for today's megawatt flash charging thermal management. We call these technologies the foundational technologies of electric vehicles. Rooted in the origin, inherited and evolved. The e-platform will always maintain its strong vitality. In recent years, intelligence has flourished. Everyone thought there was nothing more to innovate in electrification. But today, the Super e-Platform shows that electrification is still in its ascendance. There are still many unknown fields waiting for us to explore. The Super e-Platform leads the infinite possibilities of future travel transformation with disruptive innovation. Ushering in a new era of electrification. Thank you.

Now, let us focus our attention on the stage. Today's protagonist is about to drive into the light.
I believe the question you are most concerned about now is... I believe the question everyone is most concerned about now is, when can we own the Han L and Tang L? The answer is in the hands of Lu Tian, General Manager of BYD Dynasty Sales Division. Let's give him a warm round of applause.
L
Lu Tian1:19:47
It's me. I finally caught a big fish from the technology fish pond. Hello everyone, I am Lu Tian from BYD Dynasty. I believe everyone has not yet recovered from the shocking technology. 1 kilovolt, 1 kiloamp, 1 megawatt, 10°C, 30,000 rpm. Even if each of these figures is mentioned separately, it doesn't seem like technology that should exist today. They don't seem like technologies that should appear at this time. But today, they are combined so naturally. Today, I also want to share my thoughts with everyone. BYD, these three words seem to have a kind of magic. No matter how strong the technology is, as long as it's associated with BYD, it seems reasonable. We chose the Han L and Tang L as the debut models for the Super e-Platform, empowering the epoch-making flagships with epoch-making technology. When the names Han and Tang are combined with BYD's new technology, it is bound to stir up a big storm. Although Mr. Wang, Mr. Luo, and Mr. Lian just shared in a relaxed and natural way. Wang, Mr. Luo, and Mr. Lian shared in a relaxed and natural manner just now, but behind this confidence lies countless hours and effort. In the era of fuel vehicles, the Chinese auto industry was like a transfer student who joined halfway through. 0-100 km/h acceleration, number of cylinders, fuel consumption—every performance parameter felt like a curse from the Western auto industry, tightly restricting Chinese auto brands. Since then, every engineer at BYD has been holding their breath, wanting to break through these constraints with technology. It's not just us; all Chinese brands need two cars to put Chinese technology firmly at the top of the world. Against this backdrop, the Tang, the first to be equipped with 52 technologies, allowed Chinese cars to compete head-to-head with world-class products in terms of performance. The Han, the first to be equipped with the Blade Battery and silicon carbide module, gave Chinese cars the confidence to stand at the top of the world in terms of technology. We hope to use these two names, reminiscent of prosperous eras, to carry BYD's expectations for the future. At the same time, because of the names Han and Tang, through countless technological and product breakthroughs, they have gradually become a spiritual symbol, telling the story of BYD's past. This speaks of BYD's past and also points to the future of Chinese automobiles. Actually, since last year, netizens have been constantly urging for updates on the Han Tang L in my comment section. To be honest, many times, I myself couldn't resist revealing some information to everyone because I have also waited too long for this moment. Facts have proven that good technology and good products are worth the wait. On the road of new energy, Chinese brands are constantly refreshing the new heights of Chinese technology. For example, Li Auto and Zeekr's 5C supercharging, NIO's full-range 900V high-voltage platform, Huawei's Qiankun intelligent driving and Xiaomi's V8S motor are both testaments to the height of Chinese technology. In such a promising era, I've also been thinking: can we gather the strengths of all and carry on the baton? Thank you for your trust and patience. Let's focus on developing technology with a calm mind. We're willing to wait for the Han L and Tang L, dedicating them to ourselves and to you as our flagship models. From 2015 to 2020 until now, BYD has spanned several five-year periods, and we have progressed step by step. What has changed is that we've advanced step by step, using technology to stand at the top of the world. What remains unchanged is our roots in our own land, using our own culture to create cars for the Chinese people. Therefore, Chinese cars should not only have Chinese names, but also have a Chinese appearance. Han and Tang, these two IPs that hold extraordinary meaning for us, we choose to elevate them to unprecedented heights at this time. Not only because Han and Tang represent the dynasty's latest thinking on high-end product strategy, but more importantly, Han L and Tang L come with the new Loong Face dragon aesthetics, appearing before everyone as epoch-making flagships. This means not just design, but also that epoch-making technology has matured. But that groundbreaking technology has matured, and we're ready to take the baton we've been waiting for years. From the very beginning of the project, we were clear that we wanted to create epoch-making flagships. The design must be grand and high-end; it must have a Chinese style. The Han L and Tang L are over 5 meters long, with a wheelbase of nearly 3 meters and a width of nearly 2 meters. This wide body supports the grand and dignified image of China. If anyone still questions the space in new energy vehicles, once you experience the Han L and Tang L, you'll get the answer. Starting today, Han L and Tang L display vehicles will gradually arrive at the store. Cars will arrive at dealerships. Everyone is welcome to check them out and experience them firsthand. See if it's true, as netizens say, that the real car is even more stunning than the pictures. After today's launch event, I believe the value of the phrase 'BYD never plays fake' will continue to rise. For us, technology is never just rhetoric on PowerPoint; it's something we can always deliver and mass-produce. The essence of technology is innovation and breakthrough, not marketing gimmicks. This time, we're using the Han L and Tang L to debut the super e-platform because we want to tell everyone that to create a flagship car, we must use technology to deliver the value a flagship should have. To create a flagship, you need to use technology to create value. A flagship should be worthwhile and stand firm. Therefore, good technology must truly translate into user experience. I just counted 16 global firsts for the Han L EV and Tang L EV. What's even more exciting is that such great technology is launched and mass-produced. The Han L EV and Tang L EV will be the first to fully equip such stunning technology today. Starting our pre-sale... Actually, it's really difficult to fully explain the powerful technology of the Han L and Tang L EV models. Because of the countless world-class indicators, these two cars are practically impossible to find comparable references in the mass-produced family car market. Therefore, we must step outside the mass-production car category and look for competitors in more cutting-edge areas. Those who follow Formula E might know that not long ago, Formula E officially introduced a new race rule: Pit-stop super-fast charging. Interestingly, this rule requires all race cars to make a 30-second pit stop for recharging during the race, with a charging power requirement of 600 kilowatts. This was previously... Whether it's racing cars or production cars, everyone knows that Formula 1 is the highest level of performance cars in the fuel era. F1 is characterized by constantly pushing manufacturers to develop new technologies through various restrictions to improve car performance. Formula E, due to its electric architecture, gives race cars a ceiling far beyond traditional fuel architectures, creating huge room for improvement. This allows Formula E cars to invest in technology regardless of cost. However, this time, the Han L and Tang L EV models, equipped with a super platform, have achieved a charging power of 1,000 kilowatts. The charging power of the Han L far exceeds the 600 kilowatts of the new Formula E regulations, pushing racing-grade technology to even higher limits. The Han L's 810 kilowatts total vehicle power is also more than twice the standard of Formula E race cars. Furthermore, its 0-100 km/h acceleration of 2.7 seconds and top speed of over 300 km/h also meet the racing standards of Formula E. The Han L and Tang L possess technology far beyond racing grade, making mass-produced cars so powerful for the first time. If a crude parameter comparison still doesn't provide a clear understanding... I don't want to clearly show you just how impressive the super e-platform in the Han L and Tang L really is. I'd like to use a familiar scenario from daily life to illustrate this. Once, the phrase '5 minutes of charging for 2 hours of talk time' brought smartphones into the era of fast charging. Now, megawatt flash charging provides 400 km of range in 5 minutes, enough for two weeks of commuting or 4 hours of highway driving. It brings electric vehicles into a new era of parallel electric and gasoline vehicle speeds, completely ending charging anxiety. With the pace of work and life accelerating, we're making charging faster. So that life can slow down, allowing every car owner to quickly unplug the charging cable, say goodbye to long waits, and spend more time with family. From now on, warming our families. It's just 5 minutes away. Each Han and Tang SUV four-wheel drive version unleashes a maximum power of 1,102 horsepower, equivalent to the total power needed for 40 SUVs driving at high speed. This horsepower brings faster 0-100 km/h acceleration times of 2.7 seconds. By the time I finish saying these words, the Han L has already completed its 0-100 km/h acceleration. The entire process takes less than a breath. This time, the Han L represents Chinese brands and has also joined the 2-second 0-100 km/h acceleration club and the 300+ km/h top speed club. It is fully comparable to supercars costing tens of millions. The Tang L also exceeds expectations, with a tested 0-100 km/h time of 3.6 seconds and a top speed of 287 km/h. The Han L and Tang L have completely relegated gas cars to nostalgia. Perhaps the only thing that could keep up with the standard versions of the Han L and Tang L on the road. Only Lei Jun's SU7 Ultra remains. Just kidding. I still want to remind future Han L and Tang L owners: Strong performance is confidence, but safe driving is a must. If you want to let loose, I'll also do an ad here: Welcome to show off at BYD's racetracks in Hefei and Zhengzhou. Breaking limits in every dimension you can imagine. This is the pressure from Chinese technology. Today is the pre-sale launch of the Han L and Tang L. So, let me share a bit more with you. Besides their absolute lead in electric vehicle technology, the Han L and Tang L have also achieved epoch-making leadership in vehicle intelligence. The Han L and Tang L are also groundbreaking in overall vehicle intelligence, truly achieving the integration of intelligence and electrification, leading across the board. Therefore, within the matrix of groundbreaking technologies in the Han L and Tang L, we also have intelligent chassis, intelligent driving, intelligent cockpit, and the Lingyu intelligent vehicle-mounted drone system, together illuminating the technological tree of the groundbreaking flagship Han L and Tang L. With extreme performance, the chassis must certainly keep up. The intelligent chassis of the Han L and Tang L delights countless driving enthusiasts and spec lovers. Based on the previous high-end double wishbone + rear five-link suspension, it achieves a minimum turning radius of 5.6 meters. Achieving a minimum turning radius of 5.6 meters, coupled with the engineers' extreme tuning, makes the handling worthy of the groundbreaking label. Moreover, the Yunchen C intelligent damping body control system is standard on all Han L and Tang L models. The high-precision sensors of the autonomous driving system have added road preview functionality, like giving the active suspension a celestial eye, making the road ahead no longer bumpy. The entire high-end intelligent chassis solution has even more cutting-edge technologies, creating a leading-edge, next-generation experience for users in all driving scenarios. Ultra-intelligent, ultra-safe, ultra-flexible, and ultra-comfortable travel experience. Ultra-flexible and ultra-comfortable travel experience. For the Han L and Tang L, intelligent driving is just a basic question. Mr. Wang said that intelligent driving is inherently designed for safety, and it is the strongest guardian of safe travel. Such great technology should be enjoyed by everyone. The 'Eye of the Gods' B advanced intelligent driving laser version equipped on all Han L and Tang L series is a comprehensively leading, all-scenario driving and parking integrated advanced intelligent driving system. It has three core capabilities: high-speed and urban navigation, intelligent parking, and active safety. As for the actual experience... Media and users who have tested the 'Eye of the Gods' B laser version vehicles have already given the answer: first-tier intelligent driving. As for our intelligent cockpit, it is undoubtedly also BYD's traditional strength. The Han L and Tang L are equipped with the DiLink 150 intelligent cockpit, which features a 4nm customized automotive-grade cockpit chip. It boasts a 100% Android application ecosystem, compatible with all scenarios. It also features a self-developed intelligent voice AI large model and integrates with the full-fledged version of DeepSeek. Whether comparing benchmark scores or user experience, it's flagship level. But if you think such an intelligent experience isn't novel enough, why not try flying a drone? Combine travel with flight. Just recently, on March 2nd, we also released the Lingyuan intelligent vehicle-mounted drone system. The Tang L is the first to be equipped with it, achieving a new form of air-ground collaboration and a land-based aircraft carrier. Let's set off together, Lingyuan, always recording beautiful moments. Let the boundaries of travel once again break through our spatial imagination. Greatly enriching the usage scenarios of SUVs. Regarding the groundbreaking technology of the epoch-making pure electric flagship, I will stop here for today. Now, let's move on to what everyone is most concerned about, and what I also attach great importance to this time - the pricing. Pre-sale. Originally, today's technology conference did not include a pre-sale session for Han L and Tang L. I thought we should showcase all our technological trump cards first, and make it clear to everyone what exactly these two flagships named after prosperous dynasties are, what kind of effort and expectations we have put into them. Finally, we would announce the price to everyone. But recently, I couldn't withstand the pressure from the comments section of netizens anymore. To be honest, what price should Han L and Tang L be priced? What should the Tang L be set at? This question is really difficult. My team and I spent a lot of time discussing it. If we were to price it based on technical parameters, let's take a look at the current benchmarks in the market. NIO's ET9 has a maximum voltage of 925V, a maximum charging current of 765A, and a maximum charging power of 600kW, priced at 788,000 RMB. Xiaomi's SU7 Ultra has a 27,200 rpm motor, priced at 529,900 RMB. Han L and Tang L have a 1,000A motor. 1,000 kW, 30,511 rpm motor. How do you think it should be priced? My colleague, please take note of that media representative just now. I will personally deliver the car to him when it is launched. 600,000, 800,000, 1 million. Gone too far. Actually, as I just said, to build a flagship, it should create value with technology, making it worthy and stand firm. But for the Han and Tang L, we not only want to make them valuable, but also to give them unprecedented height. Why did we dare to make what seemed like risky decisions with the Han L and Tang L? The confidence lies in the names and stories of the Han L and Tang L themselves. In 2015, the first-generation Tang had a starting price of 279,800 RMB. Some people said it was a joke. Why should a Chinese car dare to be more expensive than a foreign car? In 2020, the first-generation Han was sold for 279,500 RMB. Some people also said it was a joke. Why should a new energy vehicle dare to be more expensive than a fuel car? But we used 52 technology. Technology. Blade Battery, 800V platform, silicon carbide modules, and more—one groundbreaking technology after another. Allowed Han and Tang, amidst mockery, to become the best-selling Chinese brand in the over 200,000 yuan segment upon launch. Turning those jokes into serious matters—that was also the first time. Time has allowed Chinese brands to firmly establish themselves in the over 200,000 yuan segment—a price point that was previously unimaginable. Returning to today, Chinese automobiles have risen from the bottom to the forefront, from low-end to high-end. This isn't through boasting, but through genuine technological breakthroughs—representing Chinese brands through technological innovation. The Han and Tang could do it last time, and the Han L and Tang L can do it again this time. Speaking of which, I've also finalized the pricing. Because these two cars embody the arduous pursuit of the Chinese automotive dream by countless BYD employees, and the blood, sweat, and tears of numerous engineers. Now I announce that the groundbreaking pure electric flagships, Han L EV and Tang L EV, are officially available for pre-sale starting today. The pre-sale price for Han L EV is 270,000 to 350,000 yuan, and for Tang L EV it is 280,000 to 360,000 yuan. Wait, don't rush! We have a surprise! The groundbreaking models we just released are our pure electric flagships, truly worthy of being a generation ahead. In hybrid technology, BYD also leads the way with our DM technology, unparalleled in the world. The hybrid versions of the Han L and Tang L naturally have our trump card. For users who still want to retain our dual fuel and electric energy options, the Han L and Tang L will debut with the strongest version of our DM technology, namely our four-wheel drive performance version, the DMP King Hybrid. The Tang L DM boasts a 0-100 km/h acceleration time of 4.3 seconds and a fuel consumption of 5.6 liters per 100 km in electric-depleting mode. The Han L DM achieves a 0-100 km/h acceleration time of 3.9 seconds and a fuel consumption of 4.6 liters per 100 km in electric-depleting mode. Electric-depleting mode is not only fast but also economical. These are parameter combinations you won't find in range-extended vehicles. Compared to range-extended solutions, which are limited to a single series operating condition, the DMP King Hybrid can be range-extended or direct-drive. It runs on 92-octane fuel. Even in electric-depleting mode, performance is readily available. A groundbreaking hybrid flagship should not compromise in any way for users. Capable and versatile, unfazed by extreme performance and energy consumption on high-altitude mountain roads. This is what a hybrid should be. Starting today, blind pre-orders for the Han L and Tang L DM models are officially open. And Tang L DM models are also officially available for blind ordering. Regarding the technical principles of King Hybrid, I'll briefly reveal that through the innovative application of certain cutting-edge technology, we've overcome a major technical challenge, allowing four-wheel drive hybrid performance vehicles to achieve fuel consumption close to that of two-wheel drive hybrids. More details will be discussed at the Han L and Tang L launch event in early April. Our technology is always ready for mass production upon release. Currently, the new Han L and Tang L models, equipped with a groundbreaking technology matrix, have successively arrived at our Dynasty Network dealerships. We welcome everyone to visit our stores to see and experience the cars. Everyone, please visit the stores to see and experience the cars. Please provide us with your valuable suggestions. We also welcome more Chinese brand partners to join us and move forward together, letting the world collectively feel the shocking power of Chinese technology. Thank you all.

Thank you, Mr. Wang, for the major announcement. Let's give another round of warm applause. Thank you. We also believe that the Han L and Tang L, the first to feature the Super e-platform, will certainly create a new era of new energy led by Chinese brands.
