Honda has joined a demonstration project for vehicle-to-grid (V2G) technology aimed at providing energy storage to the electrical grid while providing a financial incentive to EV drivers.
Partners in the ev2g project include: the University of Delaware; NRG Energy; BMW, which is providing 15 MINI Es; Milbank Manufacturing, which is providing charging stations based on UD technology; and AutoPort, which is installing UD control technology into the EVs.
Honda is supplying an Accord Plug-In Hybrid with added V2G capabilities. The vehicle receives signals from a grid operator via a charging station, and discharges power from its battery when electric power is requested by the grid. When the grid power supply exceeds demand, the vehicle proactively charges its battery.
Such a system has the potential to reduce or eliminate grid fluctuations, which can occur more frequently when renewable energy sources are introduced.
“The participation of global automakers like Honda will help demonstrate and refine the technology,” said Professor Willett Kempton. “The University of Delaware has been developing the technology so that vehicle batteries can be used not only for mobility but also for grid services.”
“As the US adds more intermittent resources to the grid, finding a lower cost energy storage technology that also benefits electric vehicle drivers is a great opportunity,” said NRG Executive VP Denise Wilson.
