- Align testing strategy with product requirements, standards, and customer specifications
2. Product Testing & Validation
- Perform and supervise testing at multiple levels:
- Cell / Module / Pack / Rack / Container
- Conduct key tests:
- Electrical performance (capacity, efficiency, cycle life)
- Thermal performance and heat dissipation
- Environmental testing (temperature, humidity, vibration, dust)
- Safety testing (short circuit, overcharge, thermal runaway)
- Validate BMS, EMS, and PCS integration
3. Standards & Compliance
- Ensure compliance with international standards such as:
- Support certification processes and audits
- Work with third-party labs for regulatory approvals
4. Failure Analysis & Reliability
- Perform root cause analysis (RCA) on failures
- Lead reliability testing (ALT, HALT, HASS)
- Recommend design and process improvements
5. Lab Setup & Equipment Management
- Set up and manage testing labs and infrastructure
- Identify and procure testing equipment (cyclers, thermal chambers, HV testers, etc.)
- Ensure calibration and maintenance of instruments
6. Cross-functional Collaboration
- Work closely with:
