overcharge/over-discharge, and short-circuit testing.

• Conduct environmental and mechanical robustness tests (thermal cycling, vibration,

humidity, dust ingress).

• 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.


Communication:

Strong verbal and written skills for creating clear test plans, procedures, and reports.

Ability to present validation findings to R&D, Operations, and Certification stakeholders

effectively.


Core Competencies:

• Expertise in battery pack testing methodologies for advanced chemistries.

• Proficiency in safety and environmental testing for battery packs.

• Understanding of battery integration with inverters, solar systems, and chargers.

• Hands-on experience with pack testers, DAQs, and environmental testing equipment.

Interpersonal Competencies

• Effective collaboration with R&D internal cross-functional teams.

• Proactive approach to problem-solving and continuous process improvement.

• Strong organizational and multitasking abilities.


Professional Skills Required:

• Deep understanding of lithium-ion, sodium-ion, and other advanced battery chemistries.

• Knowledge of BMS functionality, pack assembly, and safety systems.

• Skilled in operating oscilloscopes, power analysers, thermal chambers, vibration tables,

and environmental test rigs.

• Ability to execute both manual and automated testing workflows.

• Proficiency in MS Office for data analysis, reporting, and documentation.


Desirable:

• Experience in UN38.3, IEC 62133, and BIS safety certification testing.

• Knowledge of EMI/EMC testing for battery systems.

• Exposure to statistical reliability tools (Weibull, Arrhenius).


Educational Qualifications & Experience:

Bachelor’s degree in Electrical or Electronics Engineering (or related discipline).

5–10 years of hands-on experience in battery pack testing and validation in a product

design validation environment.


Industry Preferred:

Battery system manufacturers, energy storage system developers, inverter/UPS/solar

product manufacturers.


General Requirements:

• Self-motivated, process-driven, and detail-oriented.

• Strong analytical and strategic thinking skills.

• Commitment to quality, safety standards, and continuous improvement.
