IEEE 2030.5 / V2G AC Profile

This profile serves to assist EVSE and PEV manufacturers, operators, and system integrators to implement the SAE J3072 requirements using the IEEE 2030.5 protocol. SAE J3072 establishes requirements for a grid support inverter system function which is integrated into a plug-in electric vehicle (PEV) which connects in parallel with an electric power system (EPS) by way of conductively coupled, electric vehicle supply equipment (EVSE).
