The Control Pilot line circuitry examples in SAE J1772:2001 show that the current loop CP–PE is connected permanently on the vehicle side via a 2.74 kΩ resistor, making for a voltage drop from +12 V to +9 V when a cable is hooked up to the charging station, which activates the wave generator.
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 IEC 62196-2 Type 1 connector (codified under SAE J1772) is the corresponding standard for single-phase AC charging in the United States, Canada, and South Korea. [12] J1772 has a maximum output of 19.2 kW. [13]
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.
J1772 has a maximum output of 19.2 kW. [9] In North America, the same Type 2 physical connector is used for three-phase AC charging under the SAE J3068 standard, which uses Local Interconnect Network (LIN) for control signaling based on IEC 61851-1 Edition 3 Annex D. [10] [11] J3068 increases the maximum output to 166 kW using three-phase AC. [9]
The project started in February 2011, [4] [1] with an experiment aimed at generating the SAE J1772 pilot signal [5] on an Arduino-compatible ATmega328 8-Bit AVR MCU. Subsequent experiments continued until a prototype J1772-compatible controller was created. As of now, OpenEVSE powers charging stations all over the world. [6]
Mode 3: slow or fast AC charging using a specific EV multi-pin socket with control and protection functions (i.e. SAE J1772 and IEC 62196-2) Mode 4: DC fast charging using a specific charging interface (i.e. IEC 62196-3, such as CHAdeMO)
