Digital Communications for Plug-in Electric Vehicles J2931/1_201209

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

This is the second version of this document and completes the step 2 effort that specifies the digital communication protocol stack between Plug-in Electric Vehicles (PEV) and the Electric Vehicle Supply Equipment (EVSE). The purpose of the stack outlined in Figure 1 and defined by Layers 3 to 6 of the OSI Reference Model (Figure 1) is to use the functions of Layers 1 and 2 specified in SAE J2931/4 and export the functionalities to Layer 7 as specified in SAE J2847/2 (as of August 1, 2012, revision) and SAE J2847/1 (targeting revision at the end of 2012).

Communications between the EVSE and other than PEV entities such as AMI, ESI, HAN, Utility head-end, etc. as shown in Figure 2 are outside of the scope of this document. It is presumed that a bridging device will be required to carry PEV information beyond the EVSE and may be collocated with the latter.
