First Megawatt Charger for Electric Trucks Unveiled

The Technical University of Munich (TUM) has unveiled the first megawatt charger for electric trucks, a significant advancement towards making battery-powered trucks viable for long-haul cargo transport. The initial prototypes were presented at an event on the Plattling Technology Campus, with Bavarian Minister of Economic Affairs Hubert Aiwanger in attendance. This new charging post allows for a full charge sufficient for 4.5 hours of operation within a standard regulatory rest period, eliminating additional waiting time.

In Germany, road freight transport constitutes about 70% of the volume and distance, primarily relying on diesel trucks, which significantly contribute to environmental pollution. Transitioning to electric trucks could substantially reduce these emissions. The NEFTON research consortium, led by TUM’s Chair of Automotive Technology, is developing the necessary technical and infrastructure solutions.

Prof. Markus Lienkamp emphasized that battery-powered trucks have a 75% efficiency compared to 26% for fuel cells and 14% for eFuels. However, the current infrastructure for electric trucks is insufficient along major transport routes. Megawatt charging technology represents a crucial advancement in this area.

Dr. Frederik Zohm from MAN Truck & Bus highlighted that NEFTON has created technology capable of charging e-trucks at over 1,000 kW, demonstrating its readiness for real-world applications. The next steps involve expanding charging infrastructure through collaboration between policymakers, energy sectors, and vehicle manufacturers.

Minister Aiwanger praised the project for showcasing Bavaria’s high-tech capabilities and its role in shaping future mobility. He acknowledged the progress made with the Megawatt Charging System (MCS) and its potential to revolutionize truck charging times.

The NEFTON project has assessed electric truck use in logistics, revealing that while local distribution can be managed with on-site charging, long-distance transport will require a network of high-powered charging stations along highways. The project suggests installing megawatt chargers every 50 km on key routes to eliminate charging delays and is exploring the potential for even higher charging outputs of up to 3 megawatts to enhance flexibility and reduce costs.
