Goals and idea

The Energy Storage Laboratory provides state-of-the-art workplaces for teaching and research in the fields of batteries, energy storage and electromobility. The aim of the laboratory is to provide students with modernly equipped workplaces for practical trainingss and theses.
For research in the field of high-voltage battery systems and electric vehicles, the Safe Energy Storage Group also operates the "Safe Energy Storage Systems" laboratory at the CARISSMA research centre.
