The hurdles for e-mobility and autonomous driving are high. Heavy, expensive batteries, short range, and long charging times have weighed on the success of electric cars, buses and commercial vehicles. At the "Metzler meets Fraunhofer" event on February 5, 2020, Professor Matthias Klingner, Head of Fraunhofer Institute for Transportation and Infrastructure Systems in Dresden, presented quick-charging systems developed by his institute that enable traction power sufficient for a range of 400 to 500 km to be transferred to a vehicle within only minutes. In a few years, filling stations could have charging points instead of petrol pumps. Another advantage: the filling station network, unlike the charging infrastructure, is already available and completely developed.
Prof. Klingner sees great opportunities for e-mobility in bus traffic and the urban delivery system that can help to significantly reduce nitrogen oxide emissions in cities. Another factor in reducing exhaust emissions is synchronous mobility. "The highest nitrogen oxide emissions occur during start-up, for example when the traffic light turns green again. With dynamic traffic control, traffic flows better and jams are avoided. At the same time, nitrogen oxide emissions are reduced," says Prof. Klingner. In Dresden, the institute is involved in the research project "Synchronous Mobility 2023", a pilot system for networked, automated driving.
