Charging electric cars as fast as refueling a combustion engine – that’s the promise of the new platform recently unveiled by BYD. The new architecture, called the Super-e platform, introduces a number of groundbreaking technologies that set world records in the field of large-scale electric vehicle production. The core electrical components of the Super-e platform – motor, electronic control unit, and battery – have been comprehensively improved compared to existing configurations. The platform achieves a charging power of one megawatt (1,000 kilowatts), the fastest charging speed ever achieved in a production vehicle. In practice, this means that the Super-e platform can increase the range of vehicles by two kilometers per second. A five-minute flash charge provides an additional range of 400 kilometers.
The architecture features a single drive motor with an output of 580 kW. The first two models, the HAN L and TANG L models intended for the Chinese market, achieve a top speed of over 300 km/h. These high values are made possible by a new engine that can run at up to 30,000 revolutions per minute – another new benchmark for large-scale production.
“This new technology will help eliminate the biggest remaining concern among electric vehicle users. Our goal is to make electric vehicle charging as fast as refueling a combustion engine, completely eliminating users’ charging concerns. In this way, we aim to achieve ‘oil-electric parity’ in charging speed,” commented Wang Chuanfu, Chairman and President of the BYD Group, during the presentation in Shenzhen.
To achieve this parity, charging requires combining ultra-high voltage with high current. The Super-e platform is the world’s first mass-produced passenger vehicle platform with a universal kilovolt high-voltage architecture, enabling kilovolt-range capacity for the battery, motor, power supply, and air conditioning system. The Super-e platform also introduces BYD’s Flash Charging Battery, which features an ultrafast ion channel from the anode to the cathode of the battery. This enables a maximum charging current of 1,000 amperes and a maximum charging rate of 10 coulombs – both benchmarks for large-scale production. To support these rates, BYD has developed and mass-produced a new generation of automotive-grade silicon carbide (SiC) power chips. With a rated voltage of up to 1,500 volts, this is not only the industry’s first mass-produced SiC power chip, but also the chip with the highest rated voltage to date.
4,000 Megawatt Flash Charging Stations in China
The new ultrafast charging technology requires advanced charging stations to achieve its full capacity. Therefore, at the same launch event, Lian Yubo, Executive Vice President and President of BYD’s Auto Engineering Research Institute, announced that BYD has developed an industry-first, fully liquid-cooled megawatt flash charging system capable of delivering a maximum power of 1,360 kilowatts.
In the future, BYD plans to build over 4,000 megawatt flash charging stations across China. In addition to its own stations, BYD has also developed the innovative Dual-Gun Charging technology, which can instantly upgrade conventional fast chargers to ultrafast chargers and superchargers to flash chargers. This Intelligent Boost technology, another world first, ensures compatibility with public charging stations, enabling convenient charging at a wide range of locations.
BYD believes that this interaction with existing infrastructure, combined with its self-developed flash charging stations and the groundbreaking Super-e platform itself, is redefining electric mobility and strengthening China’s leadership in global electrification technology.
