•Initiated the design of a cost-effective centralized 72 V BMS for L-type 3-wheeler vehicles, to match the performance and effectiveness of market competitors like Daly and Maxwell. - Designed a 6- Layer PCB and ensured the hardware architecture met AIS 156 and ISO 26262 safety standards. - Implemented shunt-based on-board current sensing to achieve an SoC error of less than 3% while compensating for sensor thermal drift. -Integrated the BMS with existing IoT Gateway through CAN BUS to enable real-time State of Health (SoH) monitoring, live data telemetry, remote updates, and geofencing for fleet management. •Designed a BLE-based temperature monitoring device for busbar trunking systems (product-TOR Mercury), achieving 10+ years of battery life, resilient upto 240°C and reducing maintenance overhead for enterprise clients. -Many such temperature sensors are used to monitor individual busbar nodes, aggregating data to a central master IOT Gateway to visualize thermal gradients. This enables the early detection of high-resistance hotspots, facilitating predictive maintenance and hazard prevention. •Prototyped a BLE-based location tracking tag device leveraging crowdsourced location technology for Android and iOS platforms. -Designed a custom on-board F-type antenna of BLE and integrated the microcontroller (Renessas-DA14592) and peripherals within a 40mm circular 4 Layer PCB package. •Engineered an IO expansion module for the TOR Cygnus edge appliance to support industrial automation. -Designed a universal 2-wire Universal Analog Input capable of software-configurable Voltage, Current, and Temperature sensing. -Integrated PWM and Analog Outputs to control industrial actuators and CAN Bus communication for controlling with PLCs and Remote Terminal Units (RTUs).

•As the Low Voltage E-Powertrain Lead, I directed the architecture and development of low-voltage systems for Formula Student electric vehicles, focusing on reliabilty, performance and weight optimization along with EMI robustness, and efficiency. • I was responsible for the end-to-end delivery of the system. I managed the system development timeline, driving system growth, component procurement, design validation and testing to ensure all technical milestones were met within the rigid constraints of the racing season. Projects: 1. Designed a 200W Flyback Converter (470V to 14V) with 97% peak efficiency to replace the auxiliary battery to decrease overall system weight and achieve better controlability and monitoring of low voltage power to increase system efficiency. The converter had custom designed magnetics with a ETD N87 Core transformer and a 4-layer PCB optimized for EMI immunity. This reduced the overall auxiliary power supply weight by 80% replacing a 3kg 12V LiFePO4 battery. 2. Developed a modular, EMI-robust 470 V BMS on an 8-layer mixed-signal PCB using LTC6812 (ISO-SPI) and CAN Bus architecture. Achieved <2% SoC error via Enhanced Coulomb Counting while reducing BMS weight by 60% replacing the OEM BMS on the vehicle. 3. Modelled and designed a 3-Level NPC Inverter to minimize THD to <15%, increase efficiency, and reduce motor cogging torque/ ripple torque. (Matlab/Simulink) Optimized DC-link capacitor selection to maximize volumetric efficiency and mitigate voltage imbalance through precise dwell time calculations. 4. Other major responsibilities included low voltage control system design (Tractive system Active Light), harness manufacturing, documentation (FMEA, Design Documents, failure analysis and effective knowldege transfer within the team.
