The battery cell emulator is connected to the Performance real-time test system allowing
it to be used as a desk-based solution or to be integrated into a scalable rack system.

 

 

Desk-based configuration

The battery cell emulator (BCE) represents the behavior of real-world batteries and provides precise voltage and current levels.

It is ideal for requirements-based testing of battery management systems (BMS) that monitor and control batteries in electric vehicles, aircraft, and energy storage systems. Testing with the BCE ensures safe and reliable testing compared to testing with real batteries.

Each BCE unit provides 12 independently isolated cells. Several BCEs can be connected in series to obtain a system voltage of up to 1300V.

Emulate temperature sensors for testing of the BMS’ thermal management using the temperature sensor emulator (TSE). Insert fault conditions such as short circuit, or reverse polarity as part of your testing using the fault insertion unit (FIU).

Use the BCE as desk-based solution or as a scalable rack system connected to a Performance test system with over 40 I/O modules, covering thousands of I/O signals and protocols.

Like any other Speedgoat system, the BCE provides unrivaled integration into the Simulink model-based design.

Rack system

A rack system typically is equipped with following additional components:

  • High voltage (HV) terminal board: a pluggable terminal block for connection to the device under test (DUT) such as the battery management system
  • Safety switch and safety relay: safety controller that monitors inputs from switches and trips interlock
  • Insulation monitoring device: monitors insulation resistance of HV power supply cabling
  • Real-time test system: provides the option to install I/O modules covering I/O signals and protocols
  • DUT supply 12/24V: power supply for the BMS controller
  • Battery emulation supply 48V
  • Safety compartment
  • LED tower: indicates safe operation
  • (Optional) High voltage supply 1 – 1.5 kV
