The connector is circular in shape, with a flattened top edge; the original design specification carried an output electric power of 3–50 kW for charging battery electric vehicles using single-phase (230V) or three-phase (400V) alternating current (AC), with a typical maximum of 32 A 7.2 kW using single-phase AC and 22 kW with three-phase AC ...
The North American Charging System (NACS), standardized as SAE J3400, is an electric vehicle (EV) charging connector standard maintained by SAE International. [1] Developed by Tesla, Inc. , it has been used by all North American market Tesla vehicles since 2021 and was opened for use by other manufacturers in November 2022.
CCS1 (Combined Charging System Combo 1) plug as used in North America. It is an extension of the J1772 standard AC charging connector. CCS Combo 1 vehicle inlet showing the J1772 and the two DC fast-charging pins Connectors: Incomplete Combo 2 (left) showing the two large direct current (DC) pins below, while the four alternating current (AC) pins for neutral and three-phase are removed, while ...
The SAE J1772-2017 standard defines four levels of charging: AC Level 1, AC Level 2, DC Level 1, and DC Level 2. [23] Earlier released revisions of J1772 also listed a never-implemented AC Level 3 , which was considered but never implemented.
Typical public AC charger installation. Tethered (cable permanently attached) & untethered (dedicated socket outlet only) configurations. 3φ: 32A: 480V 4 EVSE rectifies AC grid & supplies DC power to EV using tethered cable with bidirectional communication – 200A: 400V DC, dedicated (IEC 62196-3) "fast DC" Current conversion handled by EVSE ...
Although the seven-pin interface is capable of passing three-phase AC power, the current implementation is limited to single-phase power. [2] In general, charging speeds are also limited by the vehicle's on board charger, which is usually less than 10 kW. The on-board charger converts the AC input power to DC.
SAE J3068 "Electric Vehicle Power Transfer System Using a Three-Phase Capable Coupler" [1] is a North American recommended practice published and maintained by SAE International. J3068 defines electrical connectors and a control protocol for electric vehicles. It has the formal title "SAE Surface Vehicle Recommended Practice J3068".
Rapid charging results in even faster recharge times and is limited only by available AC power, battery type, and the type of charging system. [21] Onboard EV chargers (change AC power to DC power to recharge the EV's pack) can be: Isolated: they make no physical connection between the A/C electrical mains and the batteries being charged. These ...
