Vehicle-to-Grid (V2G) Savings Calculator

Turn your EV into a power source. This tool estimates how much you could earn by selling stored energy from your car's battery back to the grid during peak demand hours.

How Does Vehicle-to-Grid Work?

1. Charge Off-Peak

Charge your EV overnight when electricity is cheapest.

2. Export During Peak

Sell stored energy back to the grid during evening peak hours when prices are high.

3. Profit from the Spread

You earn the difference between the high export price and the low import price.
