This SAE Information Report J2931/7 establishes the security requirements for digital communication between Plug-In Electric Vehicles (PEV), the Electric Vehicle Supply Equipment (EVSE) and the utility, ESI, Advanced Metering Infrastructure (AMI) and/or Home Area Network (HAN).

This SAE Information Report J2931/7 establishes the security requirements for digital communication between Plug-In Electric Vehicles (PEV), the Electric Vehicle Supply Equipment (EVSE) and the utility, ESI, Advanced Metering Infrastructure (AMI) and/or Home Area Network (HAN).

The SAE Recommended Practice J2954 establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety and testing for wireless charging of light duty electric and plug-in electric vehicles. The current version addresses unidirectional charging, from grid to vehicle, but bidirectional energy transfer may be evaluated for a future standard. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels 1, 2, and 3 with some variations. A standard for wireless power transfer (WPT) based on these charge levels will enable selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging, and ease of customer use. The specification supports home (private) charging and public wireless charging.

The specification supports home (private) charging and public wireless charging. In the near term, vehicles that are able to be charged wirelessly under Recommended Practice SAE J2954 should also be able to be charged by SAE J1772 plug-in chargers.
