Press Release, 3 April 2025
Exponent Energy, a startup established in 2020 by Arun Vinayak and Sanjay Byalal Jagannath, has created an ultra-fast charging for commercial electric vehicle.
Their full-stack EV charging solution includes:
- e^pack: Proprietary battery pack with 3,000-cycle warranty (industry-leading durability).
- e^pump: 1MW+ charging stations enabling 15-minute 0-100% charge 14.
- e^plug: Custom connector for seamless energy transfer 8.
Key innovations:
- Liquid cooling maintains battery temperature within 15°C during fast charging, preventing degradation 37.
- Scalable & affordable: Targets commercial fleets (e.g., e-rickshaws, buses) with 30% lower costsvs. competitors 49.
- 1.5MW chargers (coming soon) to rival BYD’s tech, focusing on India’s grid compatibility 28.
Deployed in 4+ Indian cities, Exponent’s network has powered 1,100+ batteries and 3.15M+ charging sessions, unlocking ICE-like refueling convenience for EVs
Their battery packs, constructed using standard LFP cells, are optimized for size, being 30% smaller than competitors’ products, and come with a 3,000-cycle warranty—three times the industry average.
Leadership Driving Innovation
Arun Vinayak, CEO at Exponent Energy is B.Tech in Mechanical Engineering from IIT Madras and a former founding partner and Chief Product Officer at Ather Energy. Alongside him, COO Sanjay Byalal Jagannath focuses on operational strategies, OEM relationships, and charging infrastructure implementation.
Strategic Growth
Exponent Energy is executing a strategic expansion plan, having made significant inroads into the three-wheeler segment through collaboration with Altigreen Propulsion Labs. They have already deployed over 200 electric three-wheelers, encompassing more than 1 million kilometers of operation.
Exponent Energy has successfully raised ₹380.72 crore, with its Series B funding driven by Lightspeed. Their business model yields a 15% margin on battery leases and 20% on charging fees. By 2025, Exponent aims to roll out 1,000 charging stations and support 25,000 EVs across India, with plans to enter Delhi-NCR, Mumbai, and Chennai by Q2 2025, and later explore markets in ASEAN and Africa. The company is also testing 1.5MW chargers for electric buses and plans a franchise model for charging infrastructure to reduce operational costs by 40%.
Exponent’s e^pack system focuses on utilizing standard LFP cells, optimizing smart BMS algorithms and thermal management rather than relying on custom cell compositions. Their systems function at lower voltages (48V for three-wheelers and around 400V for larger vehicles), emphasizing safety and compatibility with existing infrastructure. This allows charging power ranging from 20-50kW for smaller vehicles to 1MW for larger vehicles like buses.
