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.

This SAE Recommended Practice SAE J2847-6 establishes requirements and specifications for communications messages between wirelessly charged electric vehicles and the wireless charger. Where relevant, this document notes, but does not formally specify, interactions between the vehicle and vehicle operator. This is the 1st version of this document and captures the initial objectives of the SAE task force. The intent of step 1 is to record as much information on “what we think works” and publish. The effort continues however, to step 2 that allows public review for additional comments and viewpoints, while the task force also continues additional testing and early implementation. Results of step 2 effort will then be incorporated into updates of this document and lead to a republished version. The next revision will address the harmonization between SAE J2847-6 and ISO/IEC 15118-7 to ensure interoperability.

SAE J2847/6 establishes minimum requirements for communication between an electric vehicle and an inductive battery charging system for wireless power transfer (WPT). Where relevant, this document notes—but does not formally specify—interactions between the vehicle and vehicle operator. This document leverages the work of the SAE J2954 Alignment and Controls Sub-Team in the Wireless Power Transfer and Alignment Task Force by extending a JSON-based message set (protocol) originally developed to bench test wireless energy transfer interoperability between unmatched Ground Assembly (GA) and Vehicle Assembly (VA) systems (i.e., components manufactured by different companies). SAE J2847/6 furthers that work by adding messages sufficient to indicate that proper coil alignment has been achieved, initialize the sub-systems for wireless charging, ramp-up to full power, perform active wireless power transfer, and terminate the WPT session.

The SAE J2954 standard establishes an industry-wide specification that defines acceptable criteria for Light Duty EVs and SAE RP J2954/2 establishes the same for Heavy Duty. SAE RP SAE J2954. SAE RP J2954/3 establishes interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for dynamic wireless power transfer (D-WPT) of both light and heavy duty plug-in electric vehicles. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels as SAE J2954/1 & SAE J2954/2 with some variations. A standard for WPT based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. SAE J2954/3 addresses unidirectional charging, from grid to vehicle; bidirectional energy transfer may be evaluated for a future standard.
