BYD has revealed its new Super e-Platform in China. This electric architecture is based on the latest development of its lithium-iron-phosphate Blade battery, and it’s capable of charging at up to 1000kW. At that level, the new fast-charging tech can reportedly add 400km of range from a five minute charge. That’s double the fastest Tesla V4 superchargers, which will peak at 500kW when they roll out this year in the US.
“In order to completely solve our users’ charging anxiety, we have been pursuing a goal to make the charging time of electric vehicles as short as the refuelling time of petrol vehicles,” BYD founder Wang Chuanfu said from a Shenzhen launch event. “This is the first time in the industry that the unit of megawatt has been achieved on charging power.”

BYD has also committed to building over 4,000 ultra-fast chargers across China using the new platform.
BYD has not yet revealed the capacity of this new ‘flash charge’ battery, but with a charging voltage of up to 1000V and a maximum current of 1000A, the system can sustain 1MW (megawatt) charging power.
BYD says its testing showed the battery maintained high levels of charging power, achieving up to 600kW at a 90 per cent state of charge. Usually, the charge rate drops right off when the battery is at more than 80 per cent capacity.
The tech will debut in the updated Han L sedan and Tang L SUV, which are set for delivery in China later this year. These will also have a new gen of electric motors, said to be higher revving (spinning to just over 30,000rpm) and making 580kW. This will feature on the rear axle of the dual motor Han L and Tang L models. Combined with a less powerful unit up front, both modes will have in excess of 1000hp, enabling the sedan to hit 100km/h in 2.7sec.
