This is one of those rare situations where reading the fucking ~~manual~~ article helps:

 A standard home charger trickles power overnight at roughly 7 kilowatts, like a garden hose. A Tesla Supercharger—long considered the gold standard of public fast-charging—maxes out around 250 kilowatts. BYD is unleashing six times that amount of energy, effectively hooking the car up to a high-pressure municipal water main.

During a live demonstration onstage, BYD plugged in its new Han L sedan, making the battery jump from 10% to 80% capacity in exactly six minutes and 30 seconds.

The amperage to do that is insane, either you're dumping power from town sized feeder lines (seriously limiting where you can place those chargers) or you are charging capacitors to charge the car (wasting energy and limiting how often you can charge a car at those speeds)

They use battery banks, so the system can charge slowly without overloading the grid and charge the car quickly. But the user will pay more for charging that fast. I'd expect to have much more slower chargers and few of the fast chargers. Most supermarkets these days have a charger these days, so if you're not in a rush you can just shop and charge.

Wasting energy how exactly? Idk how efficient capacitors are in general.

What comes down to 430 miles, or about 6 hours of highway driving. It's made for the crowd that does a road trip a few times a year and really wants to drive non stop. Or those living in an apartment just want to charge once in two weeks.
