Recognizing this, SAE (the Society of Automotive Engineers) International created a new standard, Use Cases for Communication between Plug-In Vehicles and the Utility Grid (J2836/1).
The established standard uses cases for two-way communication between plug-in electric vehicles and the electric power grid, for energy transfer and other applications. It also handles multiple load management and rate programs issues that target utility companies. The various utility programs will allow consumers to charge their vehicles at the lowest cost, during off-peak hours, while also helping the utilities reduce grid impacts.
"The biggest challenge for utilities is managing the grid during peak times, a time when energy is the most expensive and demand is greatest. 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," explained Rich Scholer, HEV E/E Systems Engineer, Ford Motor Company, who is chair of SAE International's Hybrid Task Force and sponsor of the new standard.
The new standard is the first in a series of five that are being developed by SAE International to address utility programs for plug-in electric vehicles.
