Smart Charging Standards for Plug-In Electric Vehicles 2014-01-1823

This paper is the fifth in the series of documents designed to identify the progress on the SAE Plug-in Electric Vehicle (PEV) communication task force that follows 2010-01-0837, 2011-01-0866, 2012-01-1036 and 2013-01-1475.

The primary focus of this paper is to discuss the most recent revision of J2847/1 [1], which deals with Smart Charging applications, plus the initial release of J2847/3 [2], which can be thought of as dealing with “Smart Discharging” applications. Both documents are based on the use of the Smart Energy Profile 2.0 (SEP2) Application Protocol Standard (V1.0) which was completed by the ZigBee Alliance in April 2013. The standard was then accepted by the IEEE and subsequently released as IEEE 2030.5 [3].

SEP2 started with a Marketing Requirements Document (MRD) that J2836/1™ [4]expanded for the automotive Use Cases for Smart Charging, The MRD was then used to generate the SEP2 Technical Requirements Document (TRD) that set the automotive requirements in J2931/1 [5]. The TRD was used to generate a SEP2 Application Spec where the specific automotive sequence diagrams, signals and messages are contained in J2847/1. From the SAE progression, J2836/1™ Use Cases set the requirements for the signals and messages in J2847/1. J2836/3™ [6] contains the Distributed Energy Resource (DER) Use Cases for J2847/3 signals and messages, and J2931/1 contains the protocol requirements for all the SAE Plug-in Electric Vehicle communication documents.
