Chair for Electrochemical Energy Conversion and Storage Systems

The Chair of Electrochemical Energy Conversion and Storage Systems at ISEA of RWTH Aachen University conducts research at the interface between material and cell development on the one hand and mobile and stationary battery applications on the other. The focus is on the investigation and quantitative modelling of ageing processes and battery life time prediction, battery diagnostics in hardware and software, battery pack design, integration of battery systems in vehicles of all kinds and in power grids for UPS functions, grid stabilisation and integration of renewable energies. The research groups operate their own demonstration facilities and vehicles for testing batteries, as well as a fully equipped laboratory for conducting post-mortem investigations.  ISEA is a partner in the Helmholtz Institute Münster (HI MS) of the Forschungszentrum Jülich and is the scientific and organisational head of the “Center for Ageing, Reliability and Lifetime Prediction for Electrochemical and Power Electronic Systems (CARL)”, for which the research building financed by the state and federal governments is currently under construction. It offers unique interdisciplinary research opportunities for the investigation of ageing processes, service life and reliability together with institutes of electrical engineering, mechanical engineering, materials science, chemistry, physics, informatics and mathematics.

In the BattNutzung cluster, ISEA is involved in the cluster-accompanying project greenBattNutzung and in the projects NUBase, OSLiB, BALd, MADAM4Life, BetterBat, SimBAS and Model2Life. The aim of ISEA’s work in these projects is to investigate fundamental factors influencing battery ageing and safety, to create models to describe and diagnostics to monitor these processes, and to specifically match cell design and planned battery application. Whilst investigating these questions, ISEA can make use of extensive preliminary work in the area of investigating battery ageing mechanisms from projects such as eperformance, MEET-HiEnD I – III, openBat and Raffzyklen. In addition, there is in-depth experience in the field of battery system modelling from projects such as Everlasting, DUETT and HV Modal. In addition, ISEA conducts intensive research on topics related to the overall system evaluation of battery systems in projects such as BOB-LKW, Eliptic, ZeEUS and E2Fuels. Through the position of Prof. Dr. rer. nat. Dirk Uwe Sauer as cluster coordinator for the Batterienutzungskonzepte cluster, ISEA is also committed to cross-cluster networking.
