5 minutes to add 400 km of range, 1 second for 2 km of charging speed, the world's first mass-produced kilovolt high-voltage architecture - BYD's Super e-Platform is ending electric vehicle charging anxiety with a technological revolution.
On March 17, 2025, BYD unveiled the Super e-Platform technology to the world. This achievement, developed over 5 years with an investment exceeding 20 billion yuan, is not only the culmination of BYD's electrification technology but also a leap forward for the global electric vehicle industry.
The platform achieves a charging power breakthrough of 1 megawatt (1000kW) with a charging speed of "2 km per second," truly making electric vehicle charging times comparable to refueling times for gasoline vehicles.
01 Technical Architecture: Breaking Physical Limits with All-Domain Kilovolt High Voltage
The core breakthrough of the Super e-Platform lies in its world's first mass-produced passenger vehicle "All-Domain Kilovolt High-Voltage Architecture." This architecture elevates all core components including batteries, motors, power sources, and air conditioning to the 1000V voltage level, achieving a 250% compatibility improvement compared to the industry's mainstream 400-800V platforms.
Traditional 400-800V platforms face challenges of excessive current and severe heat generation when increasing charging power. BYD's kilovolt architecture reduces current by 50% at the same power level by increasing voltage and lowering current, significantly decreasing wiring losses and heat generation.
All-Domain Kilovolt High-Voltage Architecture
Covers key components such as batteries, motors, and electronic controls, achieving system comprehensive efficiency of over 95%.
Flash Charging Battery Technology
Reduces battery internal resistance by 50% by optimizing ultra-high-speed ion channels in the cathode and anode, supporting 1000A current and 10C charging rate.
30,000 RPM Ultra-High-Speed Motor
The world's first mass-produced 30,511 RPM electric drive system with a single module power reaching 580kW.
Self-Developed Silicon Carbide Power Chip
1500V automotive-grade silicon carbide chip, the highest voltage level power chip first mass-produced in the industry.
This architecture breaks through the physical limitations of traditional 400-800V platforms, setting a new benchmark for electric vehicle performance.
02 Performance: Redefining the Boundaries of Electric Vehicle Experience
Charging Efficiency: Gas-Electric Equal Speed Becomes Reality
The most notable achievement of the Super e-Platform is achieving "Megawatt Flash Charging." Test data shows that when the Han L has an initial charge level of 10%, the power reaches 997kW within 10 seconds of starting flash charging. In 5 minutes, the battery can reach 60%, adding 400 km of range.
This charging speed not only surpasses Tesla V4 Supercharging (peak power 350kW) but also leads competitors like Huawei (600kW) and Xpeng (480kW).
Power Performance: Breaking Traditional Ceilings
The Han L equipped with a 30,000 RPM motor achieves a 0-100km/h acceleration time of 2.7 seconds, with a top speed exceeding 300km/h, but with an energy consumption of only 15.3kWh per 100 km, 18% lower than competitors.
Safety Performance: Comprehensive Protection
The Super e-Platform continues BYD's safety heritage, adopting CTB (Cell-to-Body) technology, achieving a high torsional stiffness of 40,000+ N·m/°, significantly improving vehicle dynamic response and safety performance.
Thermal Management
BYD's flash charging technology also solves battery heating issues under high-rate charging conditions. Under 1000V/1000A conditions, battery temperature rise is controlled within 15°C, far lower than the industry average of 25-30°C temperature rise.
03 Platform Evolution: Technological Leap from 1.0 to Super e-Platform
The development history of BYD's e-platform can be traced back to 2010, when e-platform 1.0 was the industry's first 400V high-voltage architecture, installed in China's first mass-produced pure electric vehicle, the e6.
BYD pioneered the world's first 800V passenger vehicle high-voltage platform architecture.
e-platform 2.0 released, achieving three-in-one electric drive and three-in-one high-voltage systems, with key system platformization.
e-platform 3.0 launched, pioneering the world's first eight-in-one electric powertrain, achieving vehicle architecture platformization.
e-platform 3.0 Evo integrated the world's first twelve-in-one electric drive system.
Super e-platform released, bringing electric vehicles into the kilovolt era.
04 Application Models: Han L & Tang L Technology Empowerment
The Super e-Platform is first installed in BYD's two flagship models - the Han L and Tang L. After officially launching in April 2025, these models quickly captured the mid-to-high-end market with leading technology.
Han L EV
Pre-sale price: 270,000 - 350,000 yuan
CLTC range: 750km
Supports megawatt flash charging, adding 400 km of range in just 5 minutes.
The four-wheel-drive version has a total horsepower of 1102, with 0-100km/h acceleration in only 2.7 seconds and a top speed of 305km/h.
Tang L EV
Pre-sale price: 280,000 - 360,000 yuan
As a mid-to-large SUV, 0-100km/h acceleration is 3.6 seconds, with a top speed of 287km/h.
Also supports megawatt flash charging and is equipped with intelligent boost technology compatible with charging piles of different power levels.
05 Charging Ecosystem: Building a Megawatt Flash Charging Network
Technological breakthroughs require supporting ecosystem support. BYD plans to build more than 4,000 "Megawatt Flash Charging Stations" nationwide from 2025-2027, with each station equipped with 6-12 fully liquid-cooled super charging piles with maximum output capacity of 1360kW.
To address compatibility issues with existing charging facilities, BYD has innovated the "dual-gun charging" technology, making super charging piles instantly become flash charging piles, and fast charging piles become super charging piles. At the same time, the world's first "intelligent boost" charging technology can be fully compatible with public fast charging piles.
BYD announced that it will open and share the megawatt flash charging pile technology to the entire industry, striving to work with social capital to jointly promote the construction of megawatt-level charging facilities.
This open attitude helps accelerate the unification of charging standards across the entire industry and promote the popularization of new energy vehicles.
Conclusion and Future Outlook
BYD plans to build more than 4,000 megawatt flash charging stations nationwide by 2027 and has already opened the Super e-Platform technology for sharing across the entire industry. As kilovolt high-voltage architecture becomes the new standard, electric mobility will completely bid farewell to charging anxiety.
In the future, when electric vehicle charging becomes more convenient and efficient than refueling gasoline vehicles, we will look back on 2025 - this year, BYD's Super e-Platform rewrote the history of electric vehicles.

Yes, BYD plans to roll out Super e-Platform technology in international markets, starting with Europe and select Asian markets in late 2025, followed by other regions in 2026. The company is working on adapting the technology to meet different regional standards and certification requirements.
Traditional EV motors typically operate at 15,000-20,000 RPM. The 30,000 RPM motor in BYD's Super e-Platform provides higher power density (more power in a smaller package) and better efficiency across a wider speed range. This allows for both incredible acceleration (2.7 seconds 0-100km/h) and improved energy efficiency (15.3 kWh/100km) compared to competitors.
Vehicles built on the Super e-Platform carry a premium due to the advanced technology. The Han L EV starts at approximately 270,000 yuan (about $37,000), which is 15-20% higher than previous-generation models without this technology. However, this price includes the megawatt charging capability, significantly improved performance, and advanced features that are not available in conventional EVs at this price point.
