New standard for communication between electric vehicles and grid

Warrendale, PA, U.S.A. — (METERING.COM) — May 19, 2010 – A new standard establishing use cases for two-way communication between plug-in electric vehicles and the electric power grid, for energy transfer and other applications has been developed by the engineers association SAE International.

The standard, J2836/1 – Use Cases for Communication between Plug-In Vehicles and the Utility Grisd, is intended to provide a standard set of requirements as plug-in electric vehicles are set to become more common in garages and carports around the nation, increasing the demand on local utility grids that supply the power to charge them.

The standard also provides a set of communication requirements for use with various load management and rate programs that will be established by utility companies related to the charging of plug-in electric vehicles. The various utility programs will enable consumers to charge their vehicles at the lowest cost during off-peak hours, and helps the utilities reduce grid impacts by minimizing electric vehicle charging during peak periods.
“The biggest challenge for utilities is managing the grid during peak times, a time when energy is the most expensive and demand is greatest,” said Rich Scholer, HEV E/E systems engineer, Ford Motor Company, and chair of SAE International’s Hybrid Task Force. “As we add more plug-in electric vehicles to the grid, we’re increasing our need for on-peak power and infrastructure. This standard will help enable consumers to charge their vehicles at off-peak hours and help utilities better manage the grids during peak hours, thus minimizing cost and grid impacts.”

J2836/1 is the first is a series of five standards that are being developed by SAE International to address utility programs for plug-in electric vehicles.
