We congratulate the Institute for Power Electronics and Electrical Drives on moving into the new research building CARL – Center for Ageing, Reliability and Lifetime Prediction of Electrochemical and Power Electronic Systems – on the Melaten campus.
Three large laboratory halls as the heart of CARL and an interdisciplinary research network of ten core professorships, about 20 other chairs and institutes of RWTH Aachen and Forschungszentrum Jülich will now make it possible to push groundbreaking research work on battery aging and lifetime prediction of power electronics from a holistic perspective. “We want to understand down to the atomic and crystal level how energy storage devices function and respond to different requirements,” says Professor Dirk Uwe Sauer of ISEA, explaining the fundamental idea behind CARL.
Test benches for load and environmental simulations are set up in the first laboratory area. For example, this involves electrical, mechanical, chemical or climatic influences on the materials and systems of batteries and power electronics. Here, aging processes are run and analyzed in fast motion, as it were, in order to be able to investigate their causes in detail.
The second laboratory area deals with the construction of prototypes. The performance of entire systems or even individual components is to be examined here in order, for example, to be able to rule out material or design faults at an early stage.
Finally, the third laboratory area is dedicated to physical-electrochemical analysis. With the aid of an analysis chain for structural and material investigations, which will include a state-of-the-art computer tomograph with unprecedented resolution, the structures of the material can be examined and analyzed down to atomic resolution.
Consideration will be given to both the end user and the developer of machines and materials for the production of batteries and power electronics. “With our research results, we can help accelerate development cycles and ultimately save money by optimally configuring systems,” says Professor Sauer. This is because the question of service life is essential for economic considerations. For example, it is important for car manufacturers to be able to estimate depreciation periods, warranty services and reliability as part of functional safety.
