SAE J1772
SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".

The SAE maintains the general physical, electrical, communication protocol, and performance requirements for the electric vehicle conductive charge system and coupler. The intent is to define a common electric vehicle conductive charging system architecture including operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.
The J1772 5-pin standard supports a wide range of single-phase (1φ) alternating current (AC) charging rates. They range from portable devices that can connect to a household NEMA 5-15 outlet that can deliver 1.44 kW (12 A @ 120 V) to hardwired equipment that can deliver up to 19.2 kW (80 A @ 240 V). These connectors are sometimes informally referred to as chargers, but they are "electric vehicle supply equipment" (EVSE), since they only supply AC power to the vehicle's on-board charger, which then converts it to the direct current (DC) needed to recharge the battery.
The Combined Charging System (CCS) Combo 1 connector builds on the standard, adding two additional pins for DC fast charging up to 350 kW.
