Germany is preparing to let electric-vehicle owners sell electricity from their parked cars back to the power grid, creating a potential new revenue stream for drivers and fleet operators.
The approach relies on bidirectional charging, which allows energy to move both into a vehicle battery and out of it when the grid needs additional supply. Owners could be paid for making stored electricity available, according to InsideEVs.
Not every EV will be able to take part. Both the vehicle and its charging hardware must support the required two-way energy transfer, making technical compatibility a central condition for participation.
For Germany, the policy could turn parked EVs into a more active part of the electricity system. For buyers, fleets and charging providers, it raises the value of bidirectional capability beyond home backup power and into grid-connected energy services.
