The Battery Engineering & Safety group deals with issues relating to the development of lithium-ion battery systems and their safety. The focus is on the mechanical, electrical and thermal design of battery modules and packs consisting of prismatic, cylindrical or pouch cells. In addition, corresponding prototypes are being built, with all the necessary production resources available in the electromobility laboratory (eLab) at RWTH Aachen University, from mechanical processing of parts to 3D printing techniques and electrical contacting technology (e.g. laser welding). Finally, the Battery Abuse Center provides the infrastructure for mechanical, electrical and thermal testing and certification of battery systems.
