Battery Lab

The battery laboratory serves to research and test energy storage systems for hybrid and electric vehicles with regard to their suitability in safety-critical driving situations and for use in vehicle safety.

Objectives and Ideas

The battery laboratories serve research in the field of safe energy storage. In addition to the common battery technologies (especially lithium-ion) and capacitors, the vehicle is also considered as an overall concept. From the point of view of the rapidly advancing electrification, all operating phases of the energy storage systems must be taken into account. This includes the production and use as well as the end of the life cycle and recycling of batteries.
In the battery laboratories, facilities are available for testing individual battery cells (cell tester - 5 Volt, 800 A), battery modules (high-current test bench - up to 60 V, 4000 A, 240 kW) up to large high-voltage battery systems (high-voltage test bench - up to 800 V, 500 A, 150 kW). In addition, numerous temperature and climate chambers are available to ensure that research on energy storage systems can be carried out safely and under constantly reproducible conditions.
