Goals 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.


Energy storage test stands and battery simulators
  • 50 to 800 V, 500 A, 150 kW battery test bench / battery simulator with 1.5 m3 temperature chamber for energy storage systems and safety technology for lithium-ion batteries
  • 80 V, 4x1000 A, 240 kW battery test bench for high-current tests of battery components and 12 V, 24 V and 48 V on-board battery
  • Bitrode cell tester (8 channels; +-100 A per channel; 0 ... 5 V)
  • Neware cell tester (32 channels; +-6 A per channel; 0 ... 5 V)
  • Energy storage systems can be coupled with temperature/climate chambers from the cell and electromechanics laboratory

  • 4x160 l Memmert drying ovens
  • Digestorium for abuse tests on electromechanical components of battery systems and for cell opening
Energy storage workshop
  • 2 electronic workstations equipped with measuring technology (oscilloscopes, multimeters, CAN interface, soldering stations, hand tools etc.)
  • Development tools for various microcontrollers (Infineon, Atmel, STM, ...)
  • Software for board layout and circuit simulation
