Bengaluru-based Exponent Energy is rewriting the future of electric mobility in India with its pioneering 15-minute ultra-fast charging technology, positioning itself as a formidable disruptor in the EV ecosystem. By harnessing standard LFP cells and cutting-edge energy management solutions, Exponent is slashing operational costs and turbocharging EV adoption across the country.
Revolutionary Vision: The Minds Behind the Breakthrough
Founded in 2020 by Arun Vinayak and Sanjay Byalal Jagannath, both seasoned industry veterans, Exponent Energy is on a mission to eliminate the key roadblocks in EV adoption—slow charging, high costs, and limited battery life.
- Arun Vinayak, CEO, brings extensive experience from his time as Ather Energy’s Chief Product Officer, where he spearheaded the development of the Ather 450X, one of India’s best-selling e-scooters.
- Sanjay Byalal Jagannath, COO, is driving strategic partnerships, charging infrastructure deployment, and operational efficiency to ensure rapid scale-up.
Together, they envisioned a world where commercial EVs could charge as fast as refueling a diesel vehicle, unlocking an unprecedented level of efficiency for fleet operators.
Unleashing the Power of 15-Minute Charging
Exponent Energy’s game-changing charging system integrates three key innovations:
BMS 2.0 (Battery Management System) – Featuring proprietary algorithms that reduce lithium plating by 87%, this smart system extends battery life while enabling high-speed charging with 10× greater accuracy than conventional tech.
Advanced Thermal Control – Using a water-based liquid cooling system, Exponent ensures optimal battery temperatures between 25-40°C, allowing sustained high-speed charging without overheating.
e^Pump Charging Stations – Delivering a whopping 1MW of power, these stations enable three-wheeler EVs to charge in just 15 minutes while reducing costs by 33% through smart load balancing.
A Business Model Built for Scale & Profitability
Exponent Energy is already making waves in India’s commercial EV sector. With over 200 electric three-wheelers deployed in partnership with Altigreen Propulsion Labs, the startup has clocked over 1 million kilometers on Indian roads.
Key Revenue Streams:
- 15% margin on battery leases
- 20% margin on charging fees
With ₹380.72 crore ($46M) in Series B funding, led by Lightspeed, the company is now expanding aggressively.
Exponent Energy vs. BYD: Who Wins the EV Charging Race?
Unlike global giants like BYD, which focus on custom cell chemistry, Exponent is disrupting the game with standard LFP cells, next-gen battery algorithms, and intelligent cooling systems.
Key Differences:
- Exponent Energy: Prioritizes affordability, rapid deployment, and seamless fleet integration using low-cost, high-efficiency charging stations.
- BYD: Leverages its proprietary Blade Battery with a 1000V architecture, optimized for ultra-fast passenger vehicle charging.
The Road Ahead: Scaling to 25,000 EVs & 1,000 Charging Stations
With ambitious plans to deploy 1,000 charging stations and support 25,000 EVs by 2025, Exponent is now expanding into Delhi-NCR, Mumbai, and Chennai.
Global Expansion
Looking beyond India, the startup aims to enter ASEAN and African markets, adapting its technology to tropical climates and high-demand fleet environments.
A Sustainable Future
With an 85% grid uptime guarantee, 92% localized components, and fleet savings of up to ₹45,000 per month, Exponent Energy is powering the next phase of India’s EV revolution.
The future of electric mobility isn’t coming—it’s already here. And Exponent Energy is leading the charge. Entrepreneur Bulletin
