Broadband PLC Communication for Plug-in Electric Vehicles
This SAE Technical Information Report SAE J2931/4 establishes the specifications for physical and data-link layer communications using broadband Power Line Communications (PLC) between the plug-In electric vehicle (PEV) and the electric vehicle supply equipment (EVSE) DC off-board-charger. This document deals with the specific modifications or selection of optional features in HomePlug Green PHY v1.1 (HomePlug GP1.1) necessary to support the automotive charging application over Control Pilot lines as described in SAE J1772?. PLC may also be used to connect directly to the Utility smart meter or home area network (HAN), and may technically be applied to the AC mains, both of which are outside the scope of this document.
Rationale: SAE J2931/4 identifies the requirements for Broadband PLC Communication for Plug-in Electric Vehicles for DC energy transfer and was harmonized with DIN 70121:2014, along with J2847/2 and J2931/1. The standards team has continued to generate conformance standards and validate these requirements at several Test Events since this initial release. This revision intends to bring this document up to date with variations found and insure that items within the document are complete and accurate with the findings of the validation process.
