Volkswagen is moving to bring Vehicle-to-Grid (V2G) technology into the mainstream, announcing a fully integrated offering for private customers in Germany starting in Q4 2026.
Developed alongside Elli, the energy and charging arm of Volkswagen Group, the system aims to transform electric vehicles from simple transport tools into active participants in the energy market.
Pre-registration opens in June 2026, with expansion to other European markets planned. Rather than a standalone feature, V2G is positioned as the next step in Volkswagen’s broader home charging and energy ecosystem.
Lower Charging Costs—and Potential Income
The core appeal of V2G lies in economics. By allowing EV batteries to feed electricity back into the grid, owners can reduce charging costs and even generate revenue. Under favorable conditions, annual earnings could reach between €700 and €900.
Initially, compensation will be tied to how much flexibility drivers allow in their charging behavior. Payments will be transparent and independent of actual trading performance, offering a predictable entry point into energy markets.
Over time, the goal is more ambitious: nearly cost-neutral charging. This shifts EV ownership from a cost center toward a revenue-generating asset.
EVs as Part of the Energy System
V2G technology enables electric vehicles to act as decentralized energy storage units. Excess renewable electricity—such as solar or wind—can be stored in EV batteries and returned to the grid when demand rises.
This approach has broader implications. Analysts estimate that V2G could save Europe up to €22 billion annually in energy system costs by 2040. In Germany alone, thousands of gigawatt-hours of renewable energy are currently curtailed each year—energy that could instead be stored in EVs.
MEB Platform Enables Scale
The rollout is powered by Volkswagen’s MEB platform, which already underpins around one million EVs in Europe capable of bidirectional charging.
Upcoming updates, including ID. Software 6, will expand compatibility across more battery sizes and models. Volkswagen also emphasizes that its high-voltage battery systems are designed to handle bidirectional charging without significant long-term degradation.
Elli’s Role in the Energy Ecosystem
Elli serves as the central orchestrator of the system, connecting vehicles, infrastructure, and energy markets into a unified platform. The offering bundles several components:
– Dynamic electricity tariff
– DC bidirectional charger
– Smart meter integration
– Digital app for control and monitoring
Through aggregation of vehicle batteries and 24/7 trading on the EPEX Spot, Elli enables EV owners to participate indirectly in energy trading without complexity.
This vertically integrated approach contrasts with fragmented solutions in the market, allowing Volkswagen to maintain control over both the customer experience and value chain.
Smart Meters Unlock V2G Potential
A key requirement for V2G adoption is the installation of smart meters, which provide real-time energy usage data. Elli is working with major metering operators in Germany to streamline deployment, with installation expected within eight to ten weeks.
Once installed and configured, customers can immediately access V2G tariffs and begin optimizing their charging behavior.
The Road Ahead
Volkswagen’s V2G strategy highlights a shift in how electric mobility is defined. Beyond zero-emission driving, EVs are increasingly seen as integral components of the energy transition—balancing grids, storing renewable power, and reducing overall system costs.
With a large base of bidirectional-ready vehicles already on European roads, the 2026 launch could mark a turning point in making V2G a practical, mass-market solution.
