Battery Pack Development Engineer (R&D;) - Intern

Role Overview:

As a Trainee Battery Pack Development Engineer, you will assist the R&D; team in the design,

assembly, testing, and validation of LiFePO4/ LTO battery storage systems for electric marine applications. You will gain hands-on exposure to cell characterization, pack integration,

electrical testing, and safety protocols under the mentorship of senior battery engineers.

Key Responsibilities

● Pack Assembly & Integration Support: Assist in the mechanical and electrical assembly of prototype lithium battery packs (cell staging, busbar connections, wiring harnesses, and insulation).

● Testing & Characterization: Conduct cell- and pack-level charging/discharging tests,

capacity measurements, cycle-life evaluation, and temperature logging in accordance with standard operating procedures.

● BMS Integration Support: Assist with wiring, sensor placement (thermistors, voltage sense leads), and basic configuration testing of Battery Management Systems on assembled packs.

● Quality & Safety Compliance: Follow strict high-voltage and workshop safety standards during cell handling and battery assembly.

● Data Logging & Reporting: Record test data accurately,



assist in analyzing test results, and prepare test summary documentation for review by senior engineers.

Qualifications & Requirements

● Education: B.Tech / B.E. in Electrical and Electronics Engineering (EEE).

● Certifications / Add-on Courses: Course or certification in Electric Vehicle (EV) Systems /

Battery Technology (covering lithium cell chemistries, pack basics, and EV powertrains).

Technical Skills:

○ Clear understanding of battery cell chemistries (LiFePO4, NMC, LTO), cell specs, C ratings, and series-parallel configurations.

○ Fundamental understanding of BMS functions (SoC, SoH, over-voltage, over-current, and thermal cutoff).

○ Familiarity with electrical tools, wire crimping, harness assembly, and measuring instruments.

○ Basic awareness of EV safety practices and battery testing standards.

● Soft Skills: High attention to detail, proactive safety attitude, and a robust appetite for practical, hands-on engineering

Pay: ₹15,000.00 - ₹18,000.00 per month
