NOTE also that the *cord* for CCS2 is lighter than any comparable US standard cord, by virtue of the 3-phase AC power. To transport 11kW, you need a 16A cord in EU. For the same power in USA you need a 48A cord. 4 conductors for 16A are way lighter (and cheaper and more flexible) than 2 conductors for 48A. Tesla has attempted to mitigate some of that drawback by equipping their chargers with 4x 24A wiring, two by two in parallel to give a 48A cord. This is somewhat risky, because when one conductor fails, you try to send all of the 48A through the remaining 24A wire... And 4x 24A cord is still heavier and less flexible than 4x 16A. 3-phase always saves 1/3 of the copper of a single phase connection, that is why all distribution networks are 3-phase. In EU that extends to inside the home. NOTE that typically the home wiring is single phase and only a Range/cooktop outlet or other high power connection is wired for 3-phase, but ALL homes receive 3-phase until the meter, by default the meter was 1-phase at least until 20 years ago when I lived there. To avoid over-enhusiastic EV drivers causing blackouts, it is even a rule in many places that you can only install a 16A charging station, because the local grid operator does not like a lot of 22kW loads suddenly all jumping on the local grid and overloading it as soon as the cheap night time tariff kicks in. And 11kW is sufficient to charge overnight.
