The increasing electrification in many areas of our everyday life, but especially in industry and technology, would hardly be possible without the use of modern batteries. The challenges of the energy transition to sustainable energy supply (Energiewende) and electromobility require high-performance battery systems that are optimized specifically for the purpose of each application.
In the Battery Systems group at Fraunhofer IISB we meet the growing demand by developing innovative solutions for rechargeable electrical energy storage systems, such as lithium-ion or redox flow batteries in mobile or stationary applications. Our focus lies on the safety, lifetime and reliability of the systems. We cover the entire development process, starting with the electrical, mechanical and thermal design of battery modules and packs, and ending with commissioning and integration. This also includes cell characterization, modeling, advanced state estimation algorithms (e.g. state of health (SOH)) hardware and software development for battery and energy management systems (BMS) and energy management systems (EMS), as well as and the design of complex energy storage systems.
Our battery systems are used, for example, in electrical vehicles (EV), racing cars, motorcycles and other road vehicles as well as in aircraft, ships and submarines. We also develop stationary storage systems, e.g. for smart grid applications in combination with renewable energies. Our development processes and our documentation are requirements-driven and optimized to support our customers in their application-specific certification processes (e.g. by FAA, TÜV).
