Audi Joins the V2G Queue Hoping to Accelerate BEV Sales

Audi is the latest automaker taking a leaf out of Nissan’s BEV book and exploring vehicle-to-grid charging capabilities on its all-electric models.

Nissan has been extolling the virtues of recycling unused EV energy for some years now and has run several pilots schemes in Europe to prove the effectiveness in harnessing power and smooth out the danger of peaks and troughs in demand on the grid. Now the German carmaker is exploring the potential of using a system that could attract consumers eager to see their vehicles earn them back some revenues by selling back electricity to energy providers.

In a statement, the company pointed out the ecological advantages of using the electric car as a flexible energy storage unit. If the customer has a domestic solar power system, the electric car serves as a temporary storage medium for the generated eco-electricity. When the sun is no longer shining, the vehicle can supply the stored electricity back to the house. Bidirectional charging at home has great potential to reduce the home owner’s electricity costs and increase network stability. As a further expansion stage in combination with a home storage unit, it is possible to achieve near complete energy independence and increased security of supply in the event of a blackout.

As the number of registered electric cars increases, the number of mobile energy storage units also rises. This offers great potential, provided that the storage capacity can be used intelligently.

So Audi has teamed up with electrical installation specialist the Hager Group to develop a research and solution approach that creates financial incentives and offers greater security of supply. Martin Dehm, technical project manager for bidirectional charging at Audi, said: “Electric mobility is bringing the automotive industry and the energy sector closer together. The battery of an Audi e-tron could supply a single-family home with energy for around one week independently. Looking ahead, we want to make this potential accessible and make the electric car part of the energy transition as an energy storage device on four wheels.”
