Graduate Engineer – Battery Pack Design & Validation | Li-ion Cells, BMS, Thermal | B.Tech [EEE / Mechanical]
Summary
B.Tech [Electrical / Mechanical] graduate from [college], [city], with hands-on lithium-ion pack design experience. Built and tested a [48 V, 2.5 kWh 13S11P] NMC pack with BMS integration and thermal validation. Familiar with LFP and NMC chemistries, cell grading, AIS-156 requirements, and tools like SolidWorks, MATLAB and ANSYS. Seeking a Graduate Engineer Trainee role in battery pack design or validation.
Skills
- Battery engineering: Cell selection (LFP vs NMC, cylindrical vs prismatic), Series-parallel pack sizing, Cell grading (OCV, IR, capacity), Busbar and interconnect design, Thermal management basics, AIS-156 and AIS-038 Rev 2 awareness
- Testing: Battery cycler operation, Capacity and HPPC tests, Thermal tests with thermocouples, Insulation resistance testing
- Software: SolidWorks / CATIA, ANSYS (thermal / Fluent), MATLAB / Simulink, Excel data analysis, Python (pandas)
Experience
Intern – Battery Engineering — [Company name], [Pune / Bengaluru / Chennai][Month Year] – [Month Year]
- Graded [X] incoming 21700 cells for OCV and AC internal resistance and binned them to within [X] mΩ for pack assembly.
- Ran capacity tests on [X] modules and prepared reports that cut test data review time by [X]%.
- Supported thermal testing of a [X] kWh pack and logged peak cell temperature of [X]°C at [X]C discharge.
- Updated [X] drawings and BOMs in the PLM system under engineering change control.
Projects
48 V, 2.5 kWh NMC pack for an electric two-wheeler (final-year project)
- Sized a 13S11P pack (143 cells) from a [X] km range target using a road-load calculation.
- Designed cell holders in SolidWorks and spot-welded nickel interconnects; achieved interconnect resistance below [X] mΩ per joint.
- Integrated a [BMS model] BMS and verified over-voltage, under-voltage and over-current cut-offs on the bench.
- Kept maximum cell temperature at [X]°C under a 1C continuous discharge test at [X]°C ambient.
Thermal simulation of a 22-cell module
- Built a steady-state ANSYS model with I²R heat loads and validated it within [X]°C of thermocouple measurements.
- Compared two cooling-plate designs and recommended the one with [X]% lower temperature spread.
