Analyse BMS system and software requirements and derive verification criteria and test cases. Develop and maintain system test specifications, test procedures and test reports. Perform functional testing of BMS features, including: Cell voltage monitoring, So C, So H, So P, Battery protection and Charging/discharging functions Perform ECU and system-level testing using HIL/SIL test environments. Validate BMS behaviour under normal, boundary and fault conditions. Perform fault-injection testing, such as sensor faults, communication failures and electrical fault conditions. Test vehicle communication through CAN/CAN FD, including signal monitoring and message validation. Perform UDS diagnostic testing, including DTC validation, diagnostic services and fault recovery. Analyse CAN logs, diagnostic traces and test results to identify root causes of failures. Automate BMS test cases where applicable. Maintain bidirectional traceability between system requirements and system test cases. Participate in requirement reviews, test reviews and issue-resolution discussions with system, software, hardware and Fu Sa teams. Support test coverage analysis and release/readiness reporting.
