Vehicle-to-Grid, often abbreviated as V2G, is a technology that enables battery-powered electric vehicles to communicate with the power grid through a bidirectional charger. With V2G, electric vehicles can both receive and send electricity to the grid. The purpose is to support the power grid by contributing energy and maintaining balance. In this way, electric vehicles function as mobile energy storage units, promoting the efficient use of renewable energy.

The Vehicle-to-Home technology, commonly referred to as V2H, allows electric vehicles to serve as a flexible energy source for the home by using a bidirectional charger capable of both receiving and supplying electricity. With Vehicle-to-Home, battery-powered electric vehicles become more than just a means of transportation. By charging the vehicle when electricity prices are low or when there is a surplus of green energy, such as solar or wind power, households can save money while consuming cleaner energy. This technology also helps optimize how and when energy is used.

By using both Vehicle-to-Grid and Vehicle-to-Home technologies, electric vehicles can contribute to a smarter and more sustainable energy society. Together, these technologies enable more efficient energy use, both at home and across the community. By utilizing the electric vehicle as an energy storage unit, it supports the transition to more sustainable energy consumption.

Volkswagen has developed the MEB electric vehicle platform, which is used by several car manufacturers. All vehicles based on this platform, manufactured from week 17 of 2023 onwards and equipped with a battery larger than 77 kWh, are compatible with our service.

Vehicles produced from late 2022 up to week 17 of 2023 may be eligible for an update to become compatible. Please contact your nearest dealer for more information.

Examples of vehicles built on the MEB platform:

• All Volkswagen ID models, including the ID. Buzz

• Audi Q4 e-tron

• Škoda Enyaq and Elroq

• Cupra Born and Tavascan

• Ford Explorer and Ranger (manufactured in Europe)

There is research today showing that bidirectional charging does not necessarily have a negative impact on battery health. The power levels used in V2G and V2H are generally low (maximum 11 kW), which puts less strain on the battery compared to, for example, frequent fast charging or aggressive driving. According to studies, V2G can even help slow down capacity loss, especially if charging levels are maintained within 20–80% of the battery’s full capacity.

You can schedule your EV’s charging as usual through the vehicle’s app. The more you limit the desired charge level, the smaller the portion of the battery that will be available for use in your home or to support the power grid.

With our service, your car’s battery is never fully drained. We always maintain a minimum charge level of 30 %, or a level you have selected yourself. If you are planning a trip, simply schedule it in the vehicle’s app and we will take it into account to ensure the battery is charged according to your preferences.

No, you do not need your own energy sources. All you need is a compatible electric vehicle with bidirectional charging capability and a bidirectional charger to use our service.
