About
I am an Electric Vehicle (EV) professional with 7+ years of hands-on experience in vehicle integration, product testing & validation, and fleet operations, bringing together both technical depth in R&D and operational leadership. My expertise spans the full EV lifecycle - from new technology development and validation testing to service, maintenance, and optimization of large EV fleets. Core Strengths- R&D and Product Testing (Batteries, Vehicle): In-house validation and development testing of Metal-Air batteries at Testing agencies. Performance and certification testing of Lithium-Ion batteries as per AIS 039 & AIS 040, including cycle life, abuse testing, and compliance evaluation. Vehicle Integration & Testing: Validation of 2W/3W vehicles and EV retrofits as per KPIs and global standards, including chargers, controllers, DC-DC converters, and IoT systems. Battery Systems: Integration and testing of Li-ion and Metal-Air chemistries across swapping & non-swapping applications; hands-on with in-house pre-certification, test protocols, and AIS 156 validation. Homologation & Certification: Direct experience with Type Approval, COP, and certification testing with ICAT/ARAI and global private testing organizations. Technology & Analytics: Leveraging IoT and data analytics for vehicle performance monitoring, predictive maintenance, and root cause analysis in battery/vehicle testing. Fleet & Service Operations: Proven expertise in EV fleet optimization, technical service operations, inventory planning, and vendor evaluation with a focus on reducing OPEX. Leadership & Partnerships: Managing cross-functional technical teams, collaborating with OEMs, suppliers, and charging ecosystem partners to ensure technical reliability and cost optimization. What I Deliver- Reliable battery testing & validation frameworks for advanced chemistries (Li-ion & Metal-Air). Improved EV fleet uptime and reliability through process optimization & predictive maintenance. Cost-efficient procurement and inventory planning, reducing OPEX in EV ops. End-to-end support for technology integration projects - batteries, chargers, controllers, motors, DC-DC converters, and IoT systems. Proven results in vehicle performance testing, development validation, and model-based testing. With a strong foundation in R&D, product validation, and operational execution, I help organizations scale EV adoption with reliability, compliance, and efficiency. My focus areas include EV Testing & Validation, Battery Systems, R&D in advanced energy storage, and Program/Project Management.
