Professors Christian Klöffer and Patrick König jointly head the Electric Mobility Competence Center (EMC²) at INES.

One part of the EMC² research group conducts, headed by Prof. Dr. Christian Klöffer, research in power electronics and electric machines for mobility applications. The focus here is on use in cars and commercial vehicles as well as in pedelecs and electric flight applications. The core of the research work is the (even more) efficient operation of the components while simultaneously increasing power density. Cooperation partners include automotive and supplier companies as well as universities and EU research communities.

Another part of the EMC² group investigates, headed by Prof. Dr. Patrick König, different electric powertrain topologies (variants of the traction on-board network) with batteries and fuel cells. In the newly designed hydrogen and fuel cell lab, fuel cell systems can be analyzed and upscaled for this purpose. One aim of the research is to couple these systems with the power electronics and electrical machines for efficient overall operation.

Academic employees (doctoral students) are involved in all the research work.
