I did not get that, can you please explain ?
I meant the concerns OP has w.r.t. the powers these chargers offer. A 250kW 1kV load in industrial environment is nothing to write home about. But the technology behind a 250kW 1kV EV charger every dickhead and his dog are going to use, an appliance that is going to be driven over, pulled, squeezed and kinked, cut, sabotaged, torn apart, jammed, shorted, burnt and twisted, creates several new problems. Mainly safety problems. So when I hear about a liquid cooled, software controlled, 500A charging cable for people, I am starting to count potential safety issues that have to be solved here.
If you really feel like getting into the weeds on EV charging safety then you can look up some standards. The UL versions are free to view. Here's some to start (not all of them):
UL 2594 Standard for [AC] Electric Vehicle Supply Equipment
UL 2202 Standard for [DC (<600V)] Electric Vehicle Supply Equipment
UL 2231-1 Standard for Safety for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits: General Requirements
UL 2231-2 Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits: Particular Requirements for Protection Devices for Use in Charging Systems
For IEC:
IEC 61851 Electric vehicle conductive charging system and it's numerous parts. Good for "a rated output voltage up to 1 000 V AC or up to 1 500 V DC"
IEC 62196 Plugs, socket-outlets, vehicle connectors and vehicle inlets - Conductive charging of electric vehicles also multiple parts. - 690 V a.c. 50 Hz to 60 Hz, at a rated current not exceeding 250 A;- 1 500 V d.c. at a rated current not exceeding 400 A.

Edit:
IEC TS 63379 ED1 Plugs, socket-outlets, vehicle connectors and vehicle inlets – conductive charging of electric vehicles - Vehicle connector, vehicle inlet and cable assembly for Megawatt DC charging. WIP looks like it could be interesting, no public access yet though.
