Wait. CCS1 cant handle three-phase power?
I just read about it and no wonder its not that popular.
You can charge 7.4kw maximum in the US at home with CCS1.
In Europe you can charge up to 22kw without going DC.

CCS1 = SAE J1772 + DC.
J1772 has L1, L2/neutral, ground, control pins:

J1772 is popular where one-phase is popular in residences (i.e., US, CA). CCS2 has L1, L2, L3, and neutral+ground:

* https://en.wikipedia.org/wiki/SAE_J3068
Technically there was nothing stopping the use of CCS2 in the US, as the L2 and L3 pins would simply not be used at people's homes. But one-phase J1772 was already around, and it was decided to go with legacy compatibility.
I'm sure CCS2 exists in more commercial settings with heavy duty EVs, e.g., Volvo Trucks:

Though high/er capacity (DC) plugs are being worked on:

NACS also can't do three-phase power. Three-phase power is rare in the US, it is only found in commercial locations that need it.
Not an electrician, but here In Europe we get to 400v by combining the three 240v phases we get.
