Arc flashed are no problem I think, because these cables don't unleash the whole power before everything is connected and protocol negotiation finished.

But agree with the rest. Regardless of voltage and current, you still need half-megawatt delivery somehow.

I think the Hyundai Ioniq 5 uses an 800 volt battery. So you can get half a megawatt at 625 amps. Although most new fast chargers are about 350kw (Usually charging around 230kw on average) right now so you are only pulling about 435 amps.
