History

The first version of the AutoTram^®, developed by the Fraunhofer Institute for Transportation and Infrastructure Systems IVI in Dresden, was constructed in 2005 as a universal experimental platform for different technology developments. The fundamental structure features a series-hybrid vehicle, i.e. a serial connection of a combustion engine and a generator, power electronics and electric traction motors. This serial hybrid concept provides the possibility to integrate alternative energy storages in a simple manner via the intermediate electric circuit as backbone and is therefore an intermediate step towards a full electric drive train.
