Dirk Uwe Sauer received a diploma degree in physics from University of Darmstadt and a PhD in electrochemistry from University of Ulm. From 1992 until 2003 he worked at the Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg, as scientist, project coordinator and head of the groups on ”Storage Systems” and „Off-grid Power Supply Systems“. In 2003 he was appointed as a Juniorprofessor for “Electrochemical Energy Conversion and Storage Systems” at RWTH Aachen University (2003) in the Faculty for Electrical Engineering and Information Technology and in 2009 he became Full Professor on the same subject also at RWTH Aachen University.

The research focus is on storage systems in hybrid and full electric vehicles, energy storage in grids with a high penetration of renewable energies including economic analysis, post-mortem analysis, ageing and lifetime prediction of batteries, modelling and diagnostics for batteries, impedance spectroscopy and impedance based modelling, and energy system analysis with regard to energy storage demand. The main technologies in focus are lithium-ion batteries, lead-acid batteries, supercaps, redox-flow batteries; concepts and consequences of a CO2-free energy supply. Prof. Sauer and Prof. Winter are the chairmen of the conference “Kraftwerk Batterie”.
