System of the Month February 2025: full-power BMS testing in one rack
The Battery Cell Simulator setup combines 120 simulated cells, temperature simulation, isolation testing and fault insertion with the customer's control units in one safety cabinet.
The project configuration
- 120 simulated cells
- 24 temperature channels
- Isolation testing and fault insertion
- Integrated customer control units
Check how the BMS responds to cell, temperature and fault signals
The customer needed to test how the BMS responds to changing cell conditions, temperature signals and electrical faults. Including the control units and their connections in the setup lets the team examine these responses under controlled conditions.
Fault insertion in the integrated rack
A Fault Simulation Unit introduces electrical faults in the integrated rack so the customer can examine how the BMS detects and responds to them.
Repeat test conditions with the same wiring
You can reproduce cell, sensor and fault conditions with the same wiring. Bringing the simulated battery and the customer's electronics into one cabinet gives the team a defined setup for repeatable BMS tests.
