Experience
Senior Engineer – Battery Management Systems — [Company name], [Bengaluru / Pune / Chennai][Month Year] – Present
- Led BMS development for a [X] kWh, [X]S pack used in [X]+ vehicles on the road.
- Implemented an EKF-based SoC estimator that reduced SoC error from [X]% to under [X]% across drive cycles.
- Designed SoH estimation from field charge data; capacity estimates within [X]% of lab capacity tests.
- Defined fault reactions and open-wire detection logic; cut nuisance trips in the field by [X]%.
- Wrote technical safety requirements and supported an ASIL [C/D] safety case with the functional safety team.
BMS Firmware Engineer — [Company name], [city][Month Year] – [Month Year]
- Developed firmware for a 16S LFP BMS on [MCU], including AFE drivers, balancing and CAN messaging.
- Built a HIL test suite of [X] automated test cases, reducing regression testing time by [X]%.
- Supported AIS-156 homologation tests at [ARAI / ICAT] and closed [X] observations.
Projects
Cell-balancing optimisation for LFP fleet packs
- Analysed telematics from [X] packs and changed the balancing window and thresholds.
- Reduced average cell voltage spread at full charge from [X] mV to [X] mV, recovering about [X]% usable capacity.
