Here in North America we don’t do three phase charging, we only really have single phase and DC charging. Other than the Nissan Leaf, pretty much every recent vehicle with DC fast charging uses CCS Type 1, which is essentially J1772 (a 5-pin AC connector) with two extra DC pins at the bottom. NACS/Tesla basically combines the DC pins with the two AC pins, so the port can be smaller.
