System of the Month November 2025: high-voltage BMS validation for 800 V systems
The November 2025 project combines 216 simulated cells in a Battery Cell Simulator system for battery management system (BMS) validation in an 800 V vehicle architecture.
Cell, temperature and fault simulation
- 216 simulated cells
- NTC/PTC temperature simulation
- Isolation testing and fault insertion
- Integrated BMU and CMC drawers
Bring cell signals and BMS controllers together
The customer is developing a BMS for an 800 V vehicle architecture with around 200 cells. The test setup combines cell signals, sensing and the control units under test for validation.
Integrate the BMU and cell monitoring controllers
The Fault Simulation Unit lets the team insert faults during testing. Dedicated drawers in the cabinet house the battery management unit (BMU) and cell monitoring controllers (CMC).
Prepare the cabinet for real-time integration
The cabinet reserves space for the planned integration of a real-time PC and I/O, including ADC acquisition.
