High-performance batteries are key components in mobile and stationary electrically-powered applications, and are also the most complex elements in the system. Particularly in high energy and output ranges, the durability and reliability of a system must be high, placing significant technical demands on the batteries.

The Battery Alliance is concerned with both primary and secondary (rechargeable) systems, from small-scale applications such as button cells to large stationary systems such as redox-flow batteries.

Electrical energy storage devices in vehicles must meet a particularly wide range of (sometimes contradictory) requirements, regarding for example their cost, energy and power density, cycle stability, temperature range and safety. In order to adapt lithium ion batteries for use in vehicles, optimization is needed in a variety of areas. The institutes of the Fraunhofer-Gesellschaft have competences in virtually all of these areas.

Announcement ans Call for Papers

HIL battery simulator and e-mobility inductive power transmission system

At the International Trade Fair for Mobility which opened yesterday, the Kassel branch of Fraunhofer IWES presented two of their products within the framework of “Fraunhofer System Research for Electromobility “. The two products are a hardware-in-the-loop battery simulation system and an inductive power transmission system for electric vehicles.

Fraunhofer ISIT presents extremely robust high-power energy storage for electromobility

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.

Electromobility: Laser-based processes for lightweight battery packs

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 releases foxBMS, a universal, royalty free and fully open battery management system

Fraunhofer IISB is proud to announce the launch of its first generation, free, open, and flexible battery management system, namely foxBMS. At the conference “Batterietagung 2016” (battery-power.eu) foxBMS will be presented publicly for the first time. Visit us at Batterietagung 2016 on April 25-27 in Muenster, Germany, at the Fraunhofer Battery Alliance stand (booth 18). foxBMS will also be on show at the Fraunhofer IISB stand at the PCIM Europe 2016 from May 10-12 in Nuremberg, Germany. Currently, a total of 15 renowned industrial and research organizations from 7 countries worldwide have been selected from a long list of volunteers to participate in an intensive beta testing program. The public release of foxBMS, including all the hardware schematics, the software source code and documentation, is scheduled for the end of 2016. The system will then be available for download on www.foxbms.org.
