Electromobility presents an intriguing intersection of energy storage technology and sustainable transport solutions. Electric vehicles (EVs) rely on advanced battery systems not only for mobility but also for energy storage solutions. By optimizing the integration of EV batteries with the grid, significant synergies can be achieved. Vehicles can act as mobile energy storage units, absorbing surplus energy during low-demand periods and providing it back to the grid during peak times—a concept known as vehicle-to-grid (V2G) technology.

This synergistic approach not only enhances the reliability of the energy supply but also offers potential financial incentives for EV owners. By participating in demand response programs, users can earn compensation for allowing their vehicle batteries to support the grid. Furthermore, as the market shifts towards more sustainable practices, the technologies and strategies developed in the context of EVs could foster a more integrated and resilient energy ecosystem.
