Volkswagen Group subsidiary Elli has introduced a comprehensive Vehicle-to-Grid (V2G) offering for the German market, aiming to turn electric vehicles into mobile energy storage assets. Unveiled at the Power2Drive trade fair in Munich, the integrated product package comprises a DC bidirectional charger (Elli BiDi Charger), the Volkswagen Naturstrom V2G Flow electricity tariff, and the Elli BiDi App for energy-market participation. Eligible customers can now register their interest, with ordering planned to begin later this year.
The V2G solution is initially available to Volkswagen, Volkswagen Commercial Vehicles and CUPRA customers in Germany, covering ID. models equipped with Software 3.5 and 6 that feature a battery capacity of 77 kWh or more. Owners plug their vehicle into the Elli BiDi Charger and use the BiDi App to set availability windows and minimum state of charge. During those periods, surplus capacity can be fed back into the grid, offering potential earnings or energy-cost savings for drivers while providing grid operators with additional flexibility.
Elli, acting as the Group’s energy manager, handles tariff logic, market optimization, aggregation of battery capacity, and interface with energy markets. The Mobility House Energy contributes its FlexEngine platform and charger hardware, drawing on its experience in integrating electric vehicles into European energy systems.
With around one million MEB-based vehicles already equipped for bidirectional charging in Europe—some 360,000 in Germany—the Volkswagen Group is positioned to scale the offering across additional models and markets once regulatory and technical requirements are met. A launch incentive of up to €720 is planned in the first contract year.
This initiative aligns with wider efforts to integrate renewable energy sources and develop flexible storage solutions. Studies by Fraunhofer ISI and ISE on behalf of Transport & Environment estimate that full V2G integration across Europe could reduce annual system costs by up to €22 billion by 2040, while also addressing curtailed renewable generation.
