SAE J2931/7, Security for Plug-In Electric Vehicle Communications, has just been released. This is a new addition to the J2931 set of ground vehicle standards focused on plug-in vehicles. They center on the intersection of data communications, vehicles, and the “smart” energy grid.
The 65-page SAE J2931/7 sets security requirements for digital communication between Plug-in Electric Vehicles (PEV), the Electric Vehicle Supply Equipment (EVSE) and electric grid components. These include the utility supplier, the Energy Service Interface (ESI), the Advanced Metering Infrastructure (AMI) and/or the Home Area Network (HAN). (Boy oh boy, more acronyms!) Communications may be via wire or wireless, and may be point-to-point or internet-enabled.
The standard begins with the usual scope, referenced documents, and definitions sections. Next, logical architecture and the available interfaces for plug-in electric vehicles are reviewed. Section 5 provides you with requirements. These range from basic assumptions to authentication, authorization, privacy, and data integrity. Attention is given to the various interest areas: vehicle owner, vehicle operator, vehicle maintenance providers, passengers, energy services and providers, and so on.
Section 6 covers Use Cases. These include such things as charging locations, payments and the like. Sections 7 and 8 delve into communication issues. Section 7 is on the network and 8 is for software vulnerabilities. A brief Section 9 touches on emerging technologies.
There are a lot of interesting developments in the area of electric vehicles. Standards provide the structural support necessary for developing the new infrastructure requirements for implementing these technologies. SAE and its membership recognize the benefits of “smart” cars and a “smart” power grid. Creating the background protocols for effective and secure communication between electric vehicles and the energy grid is essential. This work is just another example of the developing inter-reliance between industry sectors not seen in the past.
