Chinese electric vehicle manufacturer BYD has revealed new fast-charging tech that can add 400km (249 miles) of range from a five minute charge. With the announcement, BYD has also promised to make a major investment in charging infrastructure, building over 4,000 of the new fast chargers across China.
The “Super e-Platform” tech is capable of charging at peak speeds of 1,000kW, double the fastest Tesla V4 superchargers, which will peak at 500kW when they roll out this year. The faster charging tech is initially available in two new vehicles, the Han L sedan and Tang L SUV, which start at 270,000 yuan (around $37,330).
“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.”
Yeah but imagine the BMS you’d need for 1MW to not have everything immediately go to hell, especially as your math puts you at 1,000 volts, 1,000 amps. You can make cables that big, and perhaps that will become standard, but this is a bit beyond comprehension with current tech.
just searched for 1000a bms’s and they don’t seem ridiculously large. unlimited length cable needs under 1cm diameter copper as code. Not crazy either. And a calculator says that 10 feet would only have 4% voltage drop at 13awg (house wire size).
