Inband Signaling Communication for Plug-in Electric Vehicles
This SAE Recommended Practice J2931/2 establishes the requirements for physical layer communications using Inband Signaling between Plug-In Vehicles (PEV) and the EVSE. This also enables the onward communications via an EVSE bridging device to the utility smart meter or Home Area Network (HAN). This is known as Frequency Shift Keying (FSK) and is similar to Power Line Carrier (PLC) but utilies the J1772™ Control Pilot circuit.
