System of the Month February 2026: compact hybrid BMS testing

Battery Cell Simulator configuration

  • Hybrid-vehicle BMS development
  • 24 cell channels
  • NTC/PTC temperature simulation
  • Fault Simulation Unit

Cell and sensor conditions for hybrid BMS development

The OEM needs repeatable battery-cell and sensor conditions for its hybrid-vehicle BMS. The compact setup brings the required electrical interfaces to the development bench.

Configure cell conditions, temperature and faults

Using the selected interfaces, the team sets cell conditions and sensor values and introduces electrical faults.

Compare BMS responses under the same conditions

The team reproduces the same cell and sensor conditions to compare software versions and investigate BMS responses. This compact configuration is designed for the hybrid BMS project at this development bench.
