What does V2G (Vehicle-to-Grid) mean?

Explanation

Vehicle-to-grid allows your EV to act as a mobile energy storage unit that feeds electricity back to the grid when demand is high. During peak hours when electricity is expensive, your car can discharge energy to the grid. During off-peak hours when electricity is cheap, it recharges. The price difference creates a potential income stream for EV owners.

V2G requires a bidirectional charger, a compatible car, an agreement with your utility, and smart software to manage the charge and discharge cycles. The system respects your settings: you define a minimum charge level (so you always have enough range for your needs) and the system only uses the surplus for grid services.

V2G is still in early commercial deployment. Pilot programs exist in the UK, Netherlands, Denmark, and several other countries. The economics are promising: some pilots show EV owners earning 500-1,000 EUR per year by participating. As renewable energy grows and the grid needs more flexibility, V2G could become a significant benefit of EV ownership.

Common confusion

V2G does not drain your battery unexpectedly. You set boundaries for minimum charge level and departure time. The system only uses surplus energy and always ensures your car is ready when you need it.
