Type 1 connector
Also called: SAE J1772 connector, J-plug Type 1 is an AC vehicle connector configuration associated with SAE J1772 and used mainly in North America and on some older imported EVs elsewhere. It is designed for single-phase AC charging. The connector carries AC power along with signalling contacts used for charging control and connection detection. In CCS1, the related Combo 1 vehicle inlet adds two large DC contacts beneath the Type 1 interface. Type 1 should not be confused with the SAE J1772 document itself. J1772 is the North American standard that defines the conductive charging method and coupler requirements; Type 1 describes the connector configuration.
