Use Cases for Plug-In Vehicle Communication as a Distributed Energy Resource
J2836/3_202402
This SAE Information Report establishes use cases for a plug-in electric vehicle (PEV) communicating with a DER Managing Entity (DME) as a distributed energy resource (DER) which is supported by SAE J2847/3. This document also provides guidance for updates to SAE J2847/2 to allow an inverter in an EVSE to use the PEV battery when operating together as either a DER or as a power source for loads which are not connected in parallel with the utility grid. Beyond these two specific communication objectives, this document is also intended to serve as a broad guide to the topic of reverse power flow (discharging) and vehicle-to-grid (V2G) technology.
Rationale:
The baseline document was first published in January 2013, and a revision was published in January 2017. One purpose of this revision is to update the document based on subsequent activities in the area of distributed energy resources and vehicle-to-grid. A major revision to SAE J3072 was published in March 2021. This was driven by the release of IEEE 1547-2018 and IEEE 1547.1-2020 and rulemaking by the California Public Utility Commission regarding V2G-AC. SAE J3072 is currently being revised to align with the soon-to-be published UL 1741 Supplement C and the SunSpec Alliance IEEE 2030.5 V2G-AC Profile.
SAE revised SAE J2847/2-202309 to include considerations for V2G-DC and V2H-DC, revised SAE 2847/3-202311 to include considerations for V2G-AC and V2H-AC, and issued SAE J2847/5-202310 to include considerations for V2L-AC and V2V-AC.
