That article is light on details. Trying to push 1000kW into an 800V drive train (current state of the art) is going to generate a LOT of heat. Is BYD going to increase the drivetrain voltage in order to bring required amperage down (and heat gen with it)? A lot of car makers haven't even made it to 800 yet.
My car could charge in well under 15 minutes if any charger in my area could make it to the advertised 350kW. My high water mark so far (after 3 months) is 185kW. Usually its closer to 80.
All EV batteries are already thermally constrained more or less. The only way this really works and scales is if they integrate cooling into the charging standards so that theres like a coolant hookup on the charge cable. Or if they've got some secret superconducting tech.
