Fraunhofer Institute for Solar Energy Systems ISE
In the field of modeling and optimization of battery systems and components, we perform research regarding thermal and electrical modeling of battery cells and modules. From the information obtained, we make comparative observations regarding cooling concepts in order to contribute to improvement. In addition, safety-related components are designed, compared and validated.
Phenomenological and Combined Electrochemical 0D Battery Models
Electrochemical battery models represent the electrical behavior, such as voltage reactions and resistance changes. We rely on phenomenological models based on equivalent circuit diagrams as well as on combined electrochemical 0D models.
These allow us not only to better understand battery cells, but also to simulate entire battery systems under load in 3D using finite element methods.
If you are interested in these topics, please feel free to contact us. We will support and advise you on test design.
Comparison of Cooling Concepts and Optimization of Homogeneity
Battery cells emit waste heat during use. Waste heat, combined with particularly cool or particularly warm ambient temperatures, has a strong influence on the electrical, thermal performance and aging behavior of battery systems.
We offer our customers the development of cooling concepts to minimize their effects on the performance and aging of battery storage systems. If you are interested in these topics, please feel free to contact us. We will support and advise you on test design.
