BYD’s new battery tech offers 300 miles in 5 minutes—Tesla’s V4 lags behind

BYD Co. shares jumped to an intra-day record after unveiling a line-up of electric vehicles supported by ultra fast-charging that the Chinese automaker says will allow them to charge almost as fast as it takes to refuel a regular car.

BYD’s new battery and charging system was capable of providing around 400 kilometers (249 miles) of range in 5 minutes in tests on its new Han L sedan, Chairman and founder Wang Chuanfu said Monday. The manufacturer will start selling vehicles with the new technology next month.
