Sweden Launches Large-Scale Pilot for Vehicle-to-Grid and Vehicle-to-Home EV Charging

A new Swedish pilot project, spearheaded by Energy Bank and Vattenfall, is testing innovative double-directional charging technology for electric vehicles (EVs), aiming to transform EVs into active contributors to the electricity grid. This project represents one of the world's largest of its kind, involving the installation of 200 double-directional chargers and engaging approximately 200 users with EVs from multiple brands.

The technology enables EV batteries to act as energy storage by charging when power prices are low and feeding electricity back into homes and the grid during high-demand periods. This approach is known as Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) charging and is expected to enhance energy system stability and reduce reliance on fossil fuels.

Magnus Berg, head of Customer Products & Solutions at Vattenfall, highlighted the significance of this technology, stating it "could play a vital role in creating a fossil-free energy system by providing flexibility and stability." The pilot follows earlier tests in a housing association in Hudiksvall and underscores the growing interest in defining electric cars not only as transport means but as integral components of energy systems, as noted by Klas Boman from Energy Bank.

Sten Forsberg, head of Volkswagen Sweden, emphasized the potential of tapping into the "underutilized resource" of EV batteries to balance the energy grid and support the green transition. This initiative is aligned with broader ambitions to integrate renewable energy sources and manage energy demand more effectively.

This project not only paves the way for innovative energy and mobility integration in Sweden but also contributes valuable experience internationally as similar efforts expand worldwide.
