SAE J2931/1-2023 PDF

Scope: This SAE Information Report, SAE J2931, establishes the requirements for the powerline carrier (PLC) digital communication between plug-in electric vehicles (PEVs), 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 specifies the digital communication protocol stack between PEVs and the EVSE. The purpose of the stack outlined in Figure 1 and defined by layers 3 to 6 of the open systems interconnection (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.
