The demonstration will take place tomorrow (16th October) in Sacremento in partnership with the Electric Power Research Institute, and will show how two-way communication between EVs and utility firms would help manage energy use and improve the efficiency of the power grid.

Developed by Sumitomo Electric, the system will enable the utilities to send a message directly to the vehicle, asking it to stop charging temporarily as a way of helping a grid that is becoming overloaded. The opt-in programme allows customers to refuse the request if desired whilst also offering incentives to participate, including the ability to recharge at a location of their choice.

‘This demonstration represents a major milestone that meets the needs of utilities and equipment manufacturers while simultaneously benefiting electric vehicle owners and electricity users,’ said Dan Bowermaster, manager of Electric Power Research Institute’s Electric Transportation Program.

Carmakers involved comprise Ford, Honda, BMW, Chrysler, GM, Toyota, Mercedes and Mitsubishi whilst utility firms involved include DTE Energy Company, Duke Energy, CenterPoint Energy Inc, Northeast Utilities, Southern California Edison, Pacific Gas & Electric Company, San Diego Gas & Electric, Commonwealth Edison, Austin Energy, ConEdison and CPS Energy.
