Signaling Communication for Wirelessly Charged Electric Vehicles
|Publication Date:||1 August 2015|
This SAE Information Report J2931/6 establishes the requirements for physical and data link layer communications between Plug-in Electric Vehicles (PEV) and the Electric Vehicle Supply Equipment (EVSE).
The purpose of J2931/6 is to complement J2954 and J2847/6 as it describes the physical layer communication between the EVSE and the PEV. The use cases for communications between a PEV and the utility are described in J2836/6™ with the message details included in J2847/6. This document is intended to describe the issues with PEV association, interoperability with various PEVs and EVSE suppliers, utilities, etc. as multiple manufacturers introduce their products. Several scenarios are encountered as the customers determine their home application to PEV energy needs that also includes the Home Area Network (HAN) that interfaces with home appliances and the utility. Some customers will interface with the utility using multifamily dwellings, street parking, energy transfer at work, businesses and these all have their variations on how the PEV communicates.
