Battery Lab - Virtual Vehicle

What Does Battery Safety Mean?

By combining simulation, modeling and our various laboratories, we accelerate the development of safer batteries.

Based on data analysis our reserarch tackles topics like powertrains and renewable energies. The findings support the development of safe batteries for all stages: predevelopment, series development, and basic research.

Our Contribution

Safety relevant parameters are used for simulation, the design for safe gas-management and to stop thermal runaway propagation
Test battery cells, battery pack materials and sensors, which will be used in safe electric cars in the future
Special designs to address every customer need or research question
Continuity in follow-up projects and services

Our Labs

Ageing Lab

In this test bench, an electrical and a thermal load can be applied to the cell. The temperature range goes down to -60°C, the current range up to 1200A and the voltage range up to 60V.

Cells and small modules up to 60V can be measured:

The following are possible:

Current profiles
Simulation of driving cycles
Continuous measurements over long periods of time
Temperature measurement using thermo couples
