During most of the operating time road vehicles run in the partial-load operational range. For short term "power-hungry" activities such as overtaking, pulling out into traffic on the highway etc. significant additional power reserves must be held available. For these power peaks Fraunhofer ISIT has developed an additional modular accumulator system in the last two years, consisting of an extremely robust high-power battery ("Li-Booster") combined with a highly responsive and power efficient battery electronics. At this year's International Motor Show in Frankfurt, Fraunhofer ISIT will present this lithium-booster-system the public.

By continuing to develop the electrification of powertrains, researchers are looking to the future of mobility in economic and environmental terms: indeed, electric mobility – based on renewable energy – provides valuable solutions for the automotive industry as it implements climate change objectives, in particular, reducing CO2 emissions. Thanks to lightweight materials, the weight of the vehicles can be reduced significantly, thus increasing their operating distance.

Fraunhofer IISB participated in the european AVTR project that has addressed the powertrain systems for light EVs. The IISB was responsible for a novel fully redundant battery system of an electric vehicle. An advanced battery management system was integrated, comprising control algorithms. The international AVTR project focused on a special EV that may fulfill the Japanese Kei Car specification. With the vehicle developed within the AVTR-project, highest modularity, low costs and reduced complexity were implemented, as well as high-end Italian product design.
