how Hyundai is developing V2G technology

Hyundai wants to support the development of renewable energies with the use of V2G (Vehicle-to-Grid) technology.

According to the latest figures from the European Environment Agency, by 2050 80% of cars in the European Union will be 100% electric. Electric vehicles are indeed booming, and this transformation in automotive use will lead to it new challenges for users, cities and local power grids.

To support the transition to electric mobility and to promote the use of renewable energies, this is innovative V2G technology (Vehicle-to-Grid) offers a possible solution: the renewable energy stored in the batteries of electric vehicles can be fed back into the grid during periods of peak energy demand, thereby optimizing the stability of electricity use.

V2G technology: projects led by Hyundai

Hyundai is already putting V2G technology into practice, with two important pilot projects in Europe, in Germany but also in Utrecht in the Netherlands, which aims to become the first bi-directional region in the world. Hyundai has partnered with mobility provider We Drive Solar to provide a fleet of Hyundai Ioniq 5 carsharing vehicles with V2G technology.

These pilot projects allow the Korean manufacturer to better understand the technical requirements for large-scale deployment of V2G, which will help balance supply and demand in the power grids.

V2G technology: how does it work?

Although V2G technology is under development, it could well be a common feature of all future electric vehicles. V2G technology allows electric grids to handle the extra load of charging many electric vehicles: models compatible with V2G technology can then serve as such energy storage device renewable to act as a buffer in the event of a peak in electricity demand.

During peak periods, when large amounts of electrical energy are being consumed, electric cars can feed electricity into the local grid to balance demand. The same vehicles can also feed renewable energy back into the grid at times when no solar or wind power can be generated, for example at night.

V2G technology: advantages and future

V2G technology can potentially bring benefits to society as a whole: if, for example, wind turbines or solar panels produce more electricity than needed, electric vehicles can store the excess and play an important role in managing the energy supply of the future.

The V2G technology also supports the stabilization of the local grid and contributes to the supply of renewable energies. In fact, most cars stay parked an average of more than 23 hours a day: by charging their vehicles at a lower cost during off-peak hours, motorists can sell the unused energy from their batteries during peak hours.

In practice, the battery of an electric car has enough power to power up to five households for 24 hours. The further development of V2G technology will make this possible support network stabilityand help reduce the load on network capacity.
