Volkswagen wants to develop V2G, “Vehicle-to-grid”: the car is integrated into the electricity grid, its battery being used to store energy.
Do you know V2G? This means “Vehicle-to-grid”, or from the vehicle to the electrical network in the language of Molière. With this technology, the energy present in the car battery can be fed back into the grid. Rather interesting in the current context of network tension.
Volkswagen wants to develop its use. Elli, its subsidiary which deals with activities related to charging in Europe, has for example just signed a memorandum of understanding with the Elia group, manager of the high voltage electricity transmission network in Belgium. The partnership aims to better integrate cars into electricity grids.
As summarized by Elke Temme, boss of Elli, the system has a triple advantage. Already, it makes it possible to better store renewable energies which cannot be produced on demand (solar energy for example). Second, cars help stabilize the power grid. Finally, the owners of the cars can make it a source of income. The battery can thus create value.

The boss of the Elia group, Chris Peeters, judges that it is important that manufacturers and electricity suppliers join forces against a backdrop of an explosion in sales of electric vehicles. The two parties thus plan to “set up joint activities in order to achieve their common objective of enhancing the advantages of integrating electric vehicles into electrical networks”, each contributing their skills.
For example, it is a question of advantageous prices to encourage drivers to charge and “unload” at the right time, but also of more technical aspects, for example the use of data from electric vehicles. Undoubtedly, other partnerships of this type will follow for VW in Europe.
