Is V2G in Our Power Future?

Vehicle-to-Grid aka V2G has the potential to utilize the idle storage capacity of BEVs while helping to stabilize power grids. Since most vehicles spend most of the time parked they can be used to feed back excess power to the grid as they sit idle and recharge when the grid has excess, (and cheaper) power available.

Polestar is developing a virtual power plant (VPP) that links all participating Polestar 3 cars connected to the grid. The cloud-based system calculates the collective capacity of connected batteries and initiates charging or discharging based on grid demand and battery longevity health. This could allow car owners to contribute to the energy transition while earning money from their unused electric energy.”
