The tech used to get such fast charging isn't revolutionary, it's just extremely (dangerous) high voltage DC charging that only exists in any capacity in China.

Also, what happens when an EV taxi runs out of battery power in China? They actually have stations setup all over that you simply drive into and it replaces the entire battery pack... in minutes.

Really no more dangerous than a 480v, 300A level 3 charger in the US. Both have enough to kill. It's not like you'd be less dead if a level 3 charger malfunctioned. They both require redundant monitoring hardware and female plugs on the hot end.

For the audience - up to 1500V, 600A. Or just shy of a Megawatt. Yowzers.

My favourite is the standard of water cooled high current high voltage cables for charging EVs...

Imo that's stepping beyond the risk profile of filling a tank with a known high explosive that can evaporate and suffocate and catch fire in the sun ... But risk profiles are inherently personal
