University of Bayreuth

The research group for methods for battery management at the University of Bayreuth develops novel methods for the model-based characterization and optimization of batteries and their operation. Here, physical models are applied across scales. The group has developed new methods that enable to directly couple microscopic and macroscopic simulations, which can be used for the multiscale analysis of surface processes at interfaces in batteries. The models are applied to find better operation strategies and diagnosis methods for lithium-ion batteries and batteries of the next generation. Electrochemical characterization of batteries with electrochemical impedance spectroscopy and nonlinear frequency response analysis is used for parameterization and validation of the models. The research is embedded in the interdisciplinary research activities at the Bavarian Center for Battery Technology (BayBatt). Here, the group works at the interface between the material research, electrochemistry, and the electrical integration on system level.
