Electric Vehicles

Standard Developed for EV-Grid Communication

May 17, 2010

WARRENDALE, PA - As plug-in electric vehicles become more common in garages and carports, there will be greater demand on local utility grids that supply the power to charge them. Recognizing the need for a standard set of requirements addressing this issue, SAE International created a new standard, "J2836/1 - Use Cases for Communication between Plug-In Vehicles and the Utility Grid."

SAE International is a global association of more than 128,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries. 

The J2836/1 standard establishes use cases for two-way communication between plug-in electric vehicles and the electric power grid. The standard is for energy transfer and other applications. Also, it 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 help the utilities reduce grid impacts by minimizing electric vehicle charging during peak periods. 

Rich Scholer, HEV E/E systems engineer for Ford Motor Co., is chair of SAE International's Hybrid Task Force and sponsor of the new standard. 

"The biggest challenge for utilities is managing the grid during peak times, a time when energy is the most expensive and demand is greatest," Scholer explained. "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 in a series of five standards being developed by SAE International to address utility programs for plug-in electric vehicles. 

"J2836/1 - Use Cases for Communication between Plug-In Vehicles and the Utility Grid" was developed by SAE International's Hybrid Task Force.
