Battery Test Benches
The CMP battery test bench allows investigating cells and entire vehicle high-voltage batteries under variable thermal conditions in a secure environment with the use of the latest pyro bubbles extinguishing devices.
In this test environment, it is possible to test the batteries in different electrical stress situations which can be implemented as a differentiated load cycles under defined boundary conditions.

Simulation and Validation Process
For a continuous simulation and validation process while researching new battery technologies, different detail levels of the underlying models are needed. This directly influences the boundary conditions for test bench measurements. There are both investigations at the cellular level - Electrochemical / material, lumped parameter models - as well as module-level possible.
Combined Power and Energy Battery
By connecting the power and energy cells by a current regulator, it is possible to achieve a weight and volume reduction. In addition, a high charge and discharge capacity is realized. The chosen combination reduces demands on the cooling system and a scalable electric range will be reached.
