Chinese EV maker BYD says fast-charging system could be as quick as filling up a tank

BYD unveils platform with charging power of 1,000 kW, which would be twice as fast as Tesla's supercharging

• Can BYD's batteries really charge in five minutes?

The Chinese electric vehicle maker BYD has unveiled a new charging system that it said could make it possible for EVs to charge as quickly as it takes to refill with petrol.

BYD's Hong Kong-listed shares gained 4.1% on Tuesday to hit a record high of 408.80 Hong Kong dollars, as investors bet that the company could strengthen its already commanding position as one of the world's biggest electric carmakers.
