Electric power train concepts

The research group for electric power chains is concerned with the applied research and development of components and systems for the electric mobility of tomorrow. Our R&D spectrum extends holistically from electrical energy supply and charging technology, and energy conversion using fuel cells, through to electrical storage and electric motors with associated transmission systems.

Our developments and research work target a wide application range, from conventional car power trains to commercial vehicles and solutions for electric aircraft.

Through our competence in design, simulation and testing, we are able to conduct research and development projects and offer research-related services holistically from the initial concept through to the realization and validation of prototypes.

Electric motors and transmission systems

The development of efficient electric motors plays an essential role in future mobility concepts. Our focus is on the development of high-voltage electric motors and transmission systems for battery-electric and hybrid powertrains. We focus on technologies with a high weight-specific power density and high efficiency. In the case of electric motors, alternative cooling concepts and winding methods are developed, along with manufacturing technologies for potential use in efficient and economic large-scale production processes for lightweight materials.

Battery systems

In the field of electric storage and battery systems, our research focuses on safe, lightweight solutions with integrated functions, which meet future demands for high energy and power densities and safety requirements during fast charging and discharging. An essential part of these developments is the design, construction and simulation of efficient thermal management systems, which are necessary to heat or cool the battery systems.

Energy supply and charging technologies

The basis for sustainable electric mobility is the efficient and sustainable provision of electrical energy. In this field we develop concepts and solutions for energy supply via inductive and connective energy supply systems. In addition to specific solutions, such as the supply of electric commercial vehicles via overhead line technologies, we also offer a holistic evaluation methodology for economic efficiency based on user behavior analyses.

Fuel cell systems

In the field of fuel cells, we research gravimetric performance enhancement via optimization in the cathode path, and via the adaptation and packaging of fuel cell systems in various stationary and mobile applications. We also carry out digital modeling, and develop digital twins for the simulative evaluation of application potential, and elaborate operational strategies based on use profiles.
