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.

Level 2 can charge up to 19kW (240V at 80A) but 12kW (50A) is more common. 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.

  How does the US get to 240v if you guys don’t have multiple phases at home? Not an electrician, but here In Europe we get to 400v by combining the three 240v phases we get.

    We don't have three phase but power coming into most panels in the United States has two 120V lines that are 180 degrees out of phase so that's enough to construct the 240.

    US power is really 240V with a neutral. It’s wired to most outlets and circuits as one 120V leg (against the neutral). But you can absolutely wire a 240V circuit using both legs and major appliances (air conditioners/heat pumps, electric driers) use 240V. My Tesla charger is on a 240V 60A circuit.

I think in the EU its CCS2 including the tesla super charger. They have https://en.wikipedia.org/wiki/Combined_Charging_System#/media/File:Iec-type2-ccs-combo2-and-iec-type2-charging-connectors-side-by-side.jpg https://en.wikipedia.org/wiki/Combined_Charging_System#/medi... the left hand plug.
