V is for Vehicle-to-Grid (V2G)

Concepts that use batteries of e-vehicles as intermediate storage and buffers for the entire power grid are called Vehicle-to-Grid (V2G). If necessary, energy from the electric vehicle fleets are fed back into the grid. Electromobility can thus help to strengthen the share of renewable energies in the electricity mix, for example by compensating for fluctuations in storage management for renewable energies. This requires bidirectional chargers to be able to feed electricity back into the grid. Conversion losses during the transformation from direct current (DC; battery) to alternating current (AC; grid) would also have to be minimised beforehand.
