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.

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.
