SAE J3072_202406

SAE J3072 establishes requirements for a grid support inverter system function that is integrated into a plug-in electric vehicle (PEV), which connects in parallel with an electric power system (EPS) by way of conductively coupled, electric vehicle supply equipment (EVSE). This standard also defines the communication between the PEV and the EVSE required for the PEV onboard inverter function to be configured and authorized by the EVSE for discharging at a site. The requirements herein are intended to be used in conjunction with IEEE 1547-2018 and IEEE 1547.1-2020 or later versions. The California Public Utility Commission directed its utilities to work with industry and standards development organizations (SDO) to develop standards to support V2G-AC. SAE J3072 was identified by CPUC as a standard to be considered for the EV. As part of this utility-led activity, UL is working on an EVSE standard, “UL 1741 Supplement SC,” that aligns with an EV certified to SAE J3072 to support V2G-AC. This standard is expected to be published in 2024. SunSpec published the “IEEE 2030.5 V2G-AC Profile Implementation Guide for SAE J3072” in June 2022. Certain changes have been made to this version to correct for errors and omissions identified during the development of these documents.
