Communication Between Plug-in Vehicles and Customers
This SAE Recommended Practice establishes the communication for the variety of potential functions for plug-in electric vehicle (PEV) customers. This includes features for use case items in SAE J2836/3 that may be PEV/customer optional equipment, such as AC vehicle-to-load (V2L) and AC vehicle-to-vehicle systems. These systems conform to SAE J1772 with variations required to identify to the PEV bidirectional onboard charger (OBC) the mode of operation changes and output requirements.
SAE has published multiple documents relating to PEV and vehicle-to-grid (V2G) interfaces. The various document series are listed below, with a brief explanation of each.Figure 1
shows the sequencing of these documents and their primary function (e.g., the SAE J2836 and SAE J2847/1 documents start with smart charging, SAE J2836 and SAE J2847/2 then adds DC charging, etc.). The intent is to have subsequent slash sheets complement each other as more functions and features are included. The /6 series of documents add wireless charging items not already included in the proceeding slash sheets. These are all then included in Interoperability in SAE J2953 and security in SAE J2931/7. SAE J3072 then includes the PEV to grid requirements for V2G power and communication to match the SAE J2836/3 use cases.
