This SAE Recommended Practice SAE J2847/1 establishes requirements and specifications for communication between plug-in electric vehicles and the electric power grid, for energy transfer and other applications. Where relevant, this document notes, but does formally specify, interactions between the vehicle and vehicle operator.
This document is being updated to address comments from the National Institute of Standards Technology (NIST) Smart Grid Interoperability Panel (SGIP) Cyber Security Working Group (CSWG) and Smart Grid Architecture Committee (SGAC) reviews. These two committees provided recommendations in order for this document to be approved for addition to the NIST SGIP Catalogue of Standards. The comments are targeted at the security statements and some definitions.
This document complements J2836/1(TM) that includes the general information and use cases by focusing on more detail information for the messages, sequence diagrams etc. Security fundamentals were included as preliminary information at the time of initial ballot and have since been updated. The task force has also determined that another document, J2931 would be used to identify the communication requirements including the security criteria. This revision to J2847/1 will therefore have the security info removed so it will not duplicate or conflict with what is placed into J2931 and include definition changes to satisfy the two committees.
