In order to avoid that solar and wind energy have to be curtailed in times of overproduction, electric cars can be used as temporary storage: As soon as they are connected to the power grid via a charging station, the electricity can be charged into the battery. Using a correspondingly enabled charging station, the electricity is fed back into the grid in times of low energy production. This is also called bi-directional charging.
With vehicle-to-grid technology, renewable energies can be used efficiently. The V2G simulator developed by LADE shows the potential behind V2G and what the power grid of the future could look like.
