The core competence of energy storage and converter addresses the development of energy storage systems, electric drives and the analysis and evaluation of complex technical energy systems. In the case of electrical, chemical and thermal energy storage systems, the focus is on material and process engineering aspects. The area of electrical drives focuses on manufacturing technology as well as the conception, design, prototypical construction and testing of electrical machines. The field of "energy system analysis" is dedicated to current issues of energy and heat supply with a focus on decarbonization.
