Rationale: 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.
