Carmakers Readying Standards for Smart Grid Interoperability

By mid 2010, the SAE aims to define standards for DC energy transfer and reverse energy flow systems from a car battery to a home or to the grid

SAN JOSE, Calif. — Auto makers hope to ratify in January the first draft of a standard that will link electric vehicles to the smart grid. Over the next year, the group aims to define a suite of five standards including ones describing ways to link electric cars to home networks.
"All the car makers are in our group and similar efforts at the ISO and IEC," said Rich Scholer, chairman of the J2293 task force at the Society of Automotive Engineers (SAE) that is developing the standards.

"People are building electric vehicles and their supply equipment right now so these things need to get sorted out," said Scholer who is also a design engineer for plug-in and fuel cell vehicles at Ford Motor Co.

"The GM Volt and other electric cars are coming out in late 2010," said Jose Salazar, a technical specialist at Southern California Edison who works with the SAE and other standards groups. "We are preparing to handle e-vehicles from [an energy] customer perspective," he said.
