The California regulations mandated the usage of SAE J1772-2001 beginning with the 2006 model year.ĬARB would later ask for higher current delivery than the 6.6 kW that the 2001 J1772 (Avcon) standard supported. This early version of the connector was made by Avcon and featured a rectangular connector capable of delivering up to 6.6 kW of electrical power. In June 2001, CARB adopted the SAE J1772-2001 standard as the charging interface for electric vehicles in California. CARB rejected the inductive technology in favor of conductive coupling to supply electricity for recharging. Early electric vehicles like the General Motors EV1 and Toyota RAV4 EV used Magne Charge (SAE J1773), an inductive system. The main stimulus for the development of SAE J1772 came from the California Air Resources Board (CARB). The older Avcon connector, featured here on a Ford Ranger EV The Combined Charging System (CCS) Combo 1 connector builds on the standard, adding two additional pins for DC fast charging up to 350 kW. 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. They range from portable devices that can connect to a household NEMA 5-15 outlet that can deliver 1.44 kW (12 amps 120 volts) to hardwired equipment that can deliver up to 19.2 kW (80 amps 240 volts). The J1772 5-pin standard supports a wide range of single-phase (1φ) alternating current (AC) charging rates. 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 SAE maintains the general physical, electrical, communication protocol, and performance requirements for the electric vehicle conductive charge system and coupler. 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". Pinouts for CCS Combo 1, looking at end of plug (attached to EVSE cord)ĬCS Combo 1 extension adds two extra high-current DC pins underneath, and the two Alternating Current (AC) pins for Neutral and Line 1 are not populated.
