This SAE Information Report J2931/7 establishes the security requirements for digital communication between Plug-In Electric Vehicles (PEV), the Electric Vehicle Supply Equipment (EVSE) and the utility, ESI, Advanced Metering Infrastructure (AMI) and/or Home Area Network (HAN).

This document describes a set of recommended actions to take to increase the likelihood of safe vehicle operation when a device (external test equipment, data collection device, etc.) whose normal operation has been compromised by a source external to the vehicle is connected to the vehicle’s diagnostic system. The term “diagnostic system” is intended to be a generic way to reference all the different ways that diagnostic commands might be injected into the system. The guidance in this document is intended to improve security without significantly impacting the ability for franchised dealer or independent aftermarket external test tools to perform legitimate diagnosis and maintenance functions. The goal is that intrusive services are only allowed to be performed when the vehicle is in a Safe State such that even if the intrusive service were to be initiated with adversarial intent the consequences of such a service would still be acceptable.

This SAE Information Report J2836 establishes the instructions for the documents required for the variety of potential functions for PEV communications, energy transfer options, interoperability and security. This includes the history, current status and future plans for migrating through these documents created in the Hybrid Communication and Interoperability Task Force, based on functional objective (e.g., (1) if I want to do V2G with an off-board inverter, what documents and items within them do I need, (2) What do we intend for V3 of SAE J2953, …).

This SAE Recommended Practice defines the Expanded Diagnostic Protocol (EDP), the requirements for the SAE J1978 OBD II Scan Tool for supporting the EDP protocol, and associated requirements for diagnosis and service information to be provided by motor vehicle manufacturers. Appendix A includes worked examples of the use of the protocol.

SMSOLUTIONS0123 represents the work of a team of policy and technical leaders from over a dozen forward-leaning organizations in the ground vehicle industry and government. When asked where Sustainable Mobility Solutions could best apply the capabilities SAE has developed over a century, the SMS group responded without hesitation: address EV charging system failure. The group determined to aggregate charging session data with the view to create a consistent data dictionary and analysis practice. Adopting agile work practices, it studied these data, vetting and iterating its solution with the objective of producing a technical report in approximately half the time required in normal standardization. The resulting document, EV Charging Infrastructure: Charging System Performance Reporting, is informing work by the U.S. Department of Energy and Departments of Energy and Transportation Joint Office, as well as OEMs and suppliers.
