BMS Tester

The test system is developed to automate functional testing, firmware programming, and validation of Battery Management System (BMS) boards and assemblies.

Project Scope

  • Automated test system with LabVIEW Software
  • Pogo pin fixtures for PCBA testing
  • Jigs with wire harness for box-build testing

Challenge

  • Cell balancing of BMS by varying individual cell voltage.
  • Charge /Discharge verification of BMS under different cell
    voltages and temperatures.

Solution

  • Automated test software in the LABVIEW test platform.
  • Battery cell simulators to provide 28 cell voltages with
    individual voltage control.
  • DAQ with multiplexer units to measure test point voltages.
  • I2C/CAN communication to read board voltages and
    temperatures.
  • Pogo pin Fixtures for PCBA testing
  • Jig with wire harness for BMS, box build testing.
  • Automated firmware download using J-link programmers.
