@Gianmarko" "have you ever seen a large arc or tig welder in action? those usually have less than 300 amps. imagine the same thing happening inside a faulty cable or connector, multiplied by 10 or more, while you charge your e-car."

Look at a few utube "arc flash" videos. Recharging a truck with 460v at 500 amps and one screw up and someone is a crispy critter.
