It sounds like a genuine attack vector to me. If someone hacked say teslas firmware supply chain and made all chargers pull max power at the same time, it could be a national infrastructure crippling attack.

Where would they dump the power? You need a load of some sort. 7kW requires a voltage drop between a hot and a neutral. If it's a 1V drop then you're going to get a hot load of amps.
