Mobility2Grid: Bus and commercial transport

Bi-Directional Charging Station for Electric Buses

In the field of bus and commercial transport, the research campus is investigating the possibility of using e-buses as energy storage systems. The buses’ scheduled standing time results in a very high predictability of available storage capacity. Compared to passenger cars, electric buses also boast much stronger batteries providing larger amounts of energy and are thus a particularly interesting option for energy storage.

Researchers at the Mobility2Grid Research Campus on the EUREF site in Berlin-Schöneberg will be the first to integrate an electric bus bi-directionally (grid-to-vehicle and vehicle-to-grid) into a local smart grid. The long-term aim is to use this innovative electric vehicle both in fixed-route service and as a high-performance energy storage system during its standing time. Siemens AG, Berlin’s public transport company Berliner Verkehrsbetriebe (BVG) and TU Berlin are collaborating in a joint project to develop and implement the necessary innovative charging technology. The system will be tested in real-life operations once the project.
