Example test: BMS response to a low cell voltage

Set one simulated cell below the controller's specified threshold and inspect the BMS measurement and diagnostic response. The other cell channels can stay at their normal inputs. The control interfaces connect the sequence to the surrounding test system. This is an illustrative test; the 72-cell configuration describes the published project.

A compact BMS setup needs deterministic control of each relevant cell and sensor input.

At a glance

  • 72 emulated cells
  • Temperature-sensor emulation
  • Real-time fault simulation
  • CAN and EtherCAT control

Set repeatable cell and sensor conditions

Simulated cell and sensor inputs provide repeatable conditions for threshold and fault tests. The team can vary the signals and examine the BMS response throughout a controlled test sequence.

Check BMS measurements, diagnostics and protection functions

The customer can use the Battery Cell Simulator as a repeatable platform for measurement, diagnostics and protection tests with defined simulated cell and sensor inputs.
