Case Study

BMS FCT / EOL / Burn-In Automated Test System

This case addresses BMS production test requirements covering FCT, EOL, burn-in, CAN/LIN communication, ADC calibration, DI/DO, Daisy Chain and test data traceability. The 24-unit parallel burn-in setup is presented as a project configuration example, not a standard system specification.

Project Overview

Automated test system case for BMS functional test, EOL, burn-in, communication, ADC calibration and production traceability.

Testing Requirements

  • Cover BMS PCBA and module-level functional tests.
  • Support CAN / LIN communication and Daisy Chain related tests.
  • Perform ADC calibration, DI/DO verification and burn-in data logging.
  • Support the 24-unit parallel burn-in project configuration.

Engineering Challenges

  • The test scope includes function, communication, calibration and long-duration burn-in.
  • Parallel test configuration requires coordinated channel, status and data management.
  • Custom control hardware must work reliably with the test software.

Implementation

  • LabVIEW test software organizes test flow, channel control, data acquisition and report output.
  • RS485 custom control hardware manages fixture, channel and peripheral signal control.
  • Communication, calibration, functional test and burn-in are integrated into one test architecture.

Engineering Outcome

  • A maintainable automated test system was built for BMS production testing.
  • The project example supports a 24-unit parallel burn-in configuration.
  • Test data can support production traceability and engineering analysis.
