- Perform accelerated life testing (HALT, endurance runs) to assess pack reliability.
- Execute BMS functional verification for pack-level applications and ensure compliance
with safety cut-offs.
- Support limited cell-level characterization and BMS testing when required.
- Operate and maintain DAQs, oscilloscopes, thermal chambers, environmental chambers,
and pack test rigs.
- Conduct Root Cause Analysis (RCA) for pack-level failures and recommend design or
process improvements.
- Analyse test data to support Design for Manufacturing (DFM) and design optimization.
- Prepare detailed technical reports with test results, deviations, conclusions, and
recommendations.
- Ensure compliance with relevant IEC, BIS, UN38.3, and other applicable standards.
