J1772 has L1, L2/neutral, ground, control pins: * https://en.wikipedia.org/wiki/SAE_J1772 https://en.wikipedia.org/wiki/SAE_J1772 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/Type_2_connector https://en.wikipedia.org/wiki/Type_2_connector * https://en.wikipedia.org/wiki/SAE_J3068 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: * https://www.volvotrucks.us/news-and-stories/press-releases/2020/august/electric-truck-charging-options-broadened-in-north-america-through-volvo-lights-project/ https://www.volvotrucks.us/news-and-stories/press-releases/2...
