Interconnection Requirements for Onboard, Grid Support Inverter Systems
This SAE J3072 Standard establishes requirements for a grid support inverter system function which 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 and IEEE 1547.1. This standard shall also support interactive inverters which conform to the requirements of IEEE 1547-2003 and IEEE 1547.1-2005, recognizing that many utility jurisdictions may not authorize interconnection.
The California Public Utility Commission issued Rulemaking 17-07-007 in July 2017 that, in part, asked “should the Commission consider issues related to the interconnection of electric vehicles and related charging infrastructure and devices and, if so, how?” A special working group, associated with this rulemaking and Rulemaking 18-12-006, was established to consider V2G-AC interconnection issues and the use of SAE J3072. Recommendations and gaps were documented in a December 2019 report. This revision is intended to address concerns raised by this report with SAE J3072. While SAE J3072 needs to support IEEE 1547-2018 and IEEE 1547.1-2020 for four-quadrant inverters, some utilities may allow for pure bidirectional inverters to be used for V2G-AC. Therefore, SAE J3072 shall continue to optionally support IEEE 1547-2003 and IEEE 1547.1-2005. This revision will also serve as a general Five-Year Review to address other issues since the original release.
