This surprises me, given that almost every country has safer electric plugs than the US. Heat is a function of current and car chargers limit themselves to less than the current the plug is rated for. "Less than" equals 80% in the US.
Could also be that for historical reasons you could have a house wired for 10 or 13 A and not be aware if it.
‘Course you can manage that by having the chargers limit themselves to 8A default (or even always), at 1800W that’s a very slow trickle but it’s something, and even if it does not fully cover your commute it spaces out carger stops or helps condition the battery on cold mornings.
That's a little more power than a US 15A, or the same as a US 20A.
There is often 3 phase power to the home in Europe, however. That allows 415V phase to phase and also 3-phase synchronous motors.
Both type E and F plugs are rated for 16, and afaik that’s generally the rating in countries which use them.
I’m sure there are others but Switzerland is the only country I know of in Europe were plugs are limited to 10 and you have to hard-wire 16.
