I was thinking about that, Tev. So, you guys don't have to upgrade your household electrics to charge EVs, right?

The reason Europe runs 220-240V is to double the voltage and halve the amperage, so the wire gauge can be smaller / cheaper. Smart in some ways, though I'm not a fan of the huge, awkward isolating plug/receptacle standards.

So, although the voltage is double, the circuit ampacity is half...so kVA is about equal.

US: 120V * 20A * 80% safety derating = 1.92 kVA
EU: 240V * 10A * 80% safety derating = 1.92 kVA

Mmmm, give me more coulombs per second - I'd say.
