SAE J 3072:2021 PDF Download

SAE J3072:2021 standard outlines the interconnection requirements for onboard, grid support inverter systems in plug-in electric vehicles (PEVs). The standard focuses on the integration of a grid support inverter system function within a PEV, allowing it to connect in parallel with an electric power system (EPS) through conductively coupled electric vehicle supply equipment (EVSE).

One of the key aspects covered by the standard is the communication protocols between the PEV and the EVSE. This communication enables the configuration and authorization of the PEV's onboard inverter function, ensuring proper discharging at a specific site. SAE J3072:2021 is designed to be used in conjunction with IEEE 1547 and IEEE 1547.1, which are standards related to grid interconnection and parallel operation of distributed energy resources.

Furthermore, the SAE J3072:2021 standard supports interactive inverters conforming to the requirements of IEEE 1547-2003 and IEEE 1547.1-2005. It recognizes that although interconnection may not be authorized in some utility jurisdictions, the standard provides a framework for those that do allow it. By providing clear guidelines and specifications, SAE J3072:2021 aims to ensure safe, efficient, and reliable interconnection between PEVs and the electric power system.
