Electric vehicles are being considered not only as consumer products but also as mobile energy storage units. V2G (vehicle-to-grid) technology allows a parked electric vehicle to feed energy from its battery back into the grid when needed. This page covers what V2G is and the concrete developments known as of 2026.

What Is V2G?

V2G is a system that operates over bidirectional charging infrastructure. The vehicle charges during cheap hours; during hours when electricity demand and prices rise, it sells part of its battery energy back to the grid. From the vehicle owner's perspective, this means the potential to earn income from a parked vehicle; from the grid's perspective, it represents a flexibility resource to balance fluctuating renewable energy production.

A Concrete Example in 2026: The Hannover ID.Buzz Pilot

V2G is not yet a widespread technology at consumer scale; however, it is being tested in real commercial fleets. The most recent example comes from Germany: Volkswagen Commercial Vehicles (VWN) and the energy company enercity announced in March 2026 that they had launched a V2G pilot project in Hannover covering a fleet of 75 ID.Buzz vehicles.

As part of the project, over the weekend of May 8-10, 2026, 12 vehicles remained connected to bidirectional charging stations continuously for 53 hours. During this period, the vehicles fed electricity into the grid, and the transactions were carried out automatically according to prices on the intraday electricity market. In other words, energy was sold when prices rose, and charging was preferred when they fell.

The Hannover pilot serves as proof that V2G has moved out of the laboratory and operates in a real commercial fleet environment with real market prices.

Which Vehicles Support V2G?

The honest answer to this question as of 2026 is limited: among the sources, the only vehicle concretely documented as actually supporting V2G, used with bidirectional charging stations, is the VW ID.Buzz pilot fleet. It is known that Tesla, BMW, Mercedes, and Chinese manufacturers will intensify competition with new electric models in 2026; however, we do not have a verifiable list of which of these models offer V2G support. We recommend that you directly confirm the manufacturer's bidirectional charging support when making your purchase decision.

The Place of V2G in the 2026 Context

2026 is interpreted as the year in which electric vehicles enter a period of maturity with solid-state batteries, autonomous driving, and V2G technology. V2G is one of the components of this transformation that is shaping the new standard for sustainable transportation. Applications such as the Hannover pilot demonstrate that the technology is no longer a conceptual idea but a priceable and measurable energy service.

The Situation in Turkey and Unknowns

To be honest: there is currently no verifiable source data on the legal regulatory status of V2G in Turkey, regulations regarding selling energy to the grid, smart charger compatibility required for home installation, or the concrete income amounts vehicle owners can earn. Likewise, we do not have up-to-date data in Turkish on home energy storage scenarios either. These topics will be added as this page is updated; we recommend approaching sources that make bold claims on these subjects with caution.

Conclusion

V2G turns the electric vehicle from a mere means of transportation into an active part of the energy ecosystem. The 53 hours of electricity sales to the grid by the ID.Buzz fleet in Hannover shows that this vision is now being tested in the field, not just on paper, in 2026. When the legal framework and infrastructure for home users become clear in Turkey, the future of home charging with your vehicle will become far more concrete than it is today.
