SAE International Heading DOE-Funded Interoperability Project for Electric Vehicles

WARRENDALE, Pa., July 23, 2013 - As manufacturers seek greater acceptance of plug-in vehicles, they face the challenges of creating a reliable, easy-to-use infrastructure for recharging and uniform testing procedures.

SAE International is helping meet that need.

SAE International is assisting in the management of an interoperability project, funded by the U.S. Department of Energy, for plug-in electric vehicles. As part of the project, SAE International will solicit the input of OEMs and electric vehicle supply equipment manufacturers (ESVE) to develop industry standards and testing procedures for plug-in electric vehicles and charging stations. These standards and procedures will increase public confidence and acceptance of plug-in electric vehicles by ensuring that the vehicles are able to accept a charge from charging stations manufactured by multiple manufacturers.

SAE International is performing the work under contract with ECOtality, which has been contracted by the Department of Energy to address advanced vehicle technologies.

“This is an essential step toward overcoming one of the hurdles in the area of electric vehicle acceptance,” said Keith Wilson, Technical Project Manager for SAE International. “The public needs convenience of use, reliability and safety. Once uniform standards have been developed for recharging stations, we will have helped to address some of the current concerns about electric vehicle charging.”

As with most new technologies, testing procedures are largely internal – conducted by OEMs and EVSE manufacturers. The interoperability project will result in uniform standards and testing procedures for wide-spread industry use.

“Once the SAE J2953 Interoperability technical committee completes the development of uniform standards and testing procedures, the likelihood of interoperability problems will decrease dramatically,” Wilson said. “The industry understands the value of successfully completing this next step. That is why we have the support of both OEM and EVSE manufacturers for this important project. Simply put, it’s critical to the future success of electric vehicles and their widespread acceptance by the public.”

The uniform testing procedures will be developed for SAE International’s standard, “J1953/2 - Test Procedures for the Plug-In Electric Vehicle (PEV) Interoperability with Electric Vehicle Supply Equipment (EVSE).

OEMs, EVSE manufacturers and other parties interested in participating in the interoperability project should contact Keith Wilson via email at
