Electric trucks can not only charge using electricity but also store and discharge it selectively - like a power bank on wheels. This is demonstrated by the SPIRIT-E project after three years of research. The consortium has now presented the results of its joint work at a public online closing event.
The SPIRIT-E project ran from August 2023 to October 2026. Funded by the German federal government and led by the DLR (German Aerospace Center), this research initiative aimed to identify existing barriers to the electrification of heavy-duty transport and develop practical solutions. On one hand, the project team pursued the approach of opening private charging infrastructure at logistics sites to third parties, including the creation of reservation options (a practice already widely adopted today). On the other, SPIRIT-E tested how bidirectional charging and reservable private charging infrastructure could be integrated into existing energy systems to drive sector coupling between the energy and transport sectors.
Shell Business Recharge Solutions (SBRS), a Shell Group company, developed the corresponding bidirectional DC charging infrastructure within the project, thereby establishing the technical foundation for all Vehicle-to-X applications. The consortium also included the Technical University of Munich (TUM) as the lead partner, the Fraunhofer IEE, the Research Centre for Energy Economics, TenneT, Hubject, Consolinno Energy, and MAN Truck & Bus. The solutions were tested in a real-world laboratory at the Schmid logistics company in Obertraublingen near Regensburg. In spring 2026, the project team carried out the world’s first live demonstration of bidirectional charging for an electric truck.
