This SAE Information Report establishes use cases for a Plug-in Electric Vehicle (PEV) communicating with an Energy Management System (EMS) as a Distributed Energy Resource (DER). The primary purpose of SAE J2836/3™ is to define use cases which must be 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 a distributed energy resource (DER).
This document will use both SAE J2836/1™ (charging the PEV using existing and optimized Utility programs) and SAE J2836/2™ (DC charging) as a basis and then add the additional information for the Plug-In Electric Vehicles (PEV) to function as a Distributed Energy Resource (DER). It is expected that including DER functions to a PEV provides a more complete solution to Smart Charging that includes Reverse Power Flow and other opportunities to stabilize the local grid distribution network and its transformers.
This is the first version of this document and completes step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 is to record as much information on “what we think works” and publish. The effort will continue to step 2 that allows public review for additional comments and viewpoints, while the task force also continues additional testing and early implementation. Results of step 2 effort will then be incorporated into updates of this document and lead to a republished version.
