J1772 is the standard AC charging connector used by most non-Tesla electric cars in North America, also called the Type 1 connector. It is named after SAE International’s standard document number, SAE J1772, which defines the connector and the signalling between charger and car. Public Level 2 stations in the US use J1772 connectors widely, and federal NEVI rules require a permanently attached J1772 connector on funded AC Level 2 ports.
