Scope

This SAE Recommended Practice establishes requirements and specifications for communication between plug-in electric vehicle (PEV) and the DC off-board charger. Where relevant, this document notes, but does not formally specify, interactions between the vehicle and vehicle operator. This document applies to the off-board DC charger for conductive charging, which supplies DC current to the rechargable energy storage system (RESS) of the electric vehicle through a SAE J1772 coupler. Communications will be on the SAE J1772 pilot line for PLC communication. The details of powerline communications (PLC) are found in SAE J2931/4. This document supports DC energy transfer via forward power flow (FPF) from source to vehicle. SAE has published multiple documents relating to PEV and vehicle-to-grid interfaces. The various document series are listed below, with a brief explanation of each.
