India's electric vehicle (EV) industry is undergoing a rapid transformation, but one of the biggest challenges remains—charging infrastructure. Despite government incentives and a push for cleaner mobility, EV adoption in India has been slowed by long charging times, high infrastructure costs, and limited fast-charging networks.
Most existing charging stations take hours to fully recharge an EV, making it impractical for commercial fleets that require high uptime. Addressing this gap, Bengaluru-based Exponent Energy is making waves in the sector with its ultra-fast charging technology.
Building Smarter, Faster EV Networks
Exponent Energy is a pioneer electric vehicle startup from the city of Bengaluru which is trying to solve this issue with its ultra-fast charging technologies. Using their ultra-fast charging techniques, Exponent Energy aims to provide commercial-level charges for EVs within 15 minutes of power consumption, cutting the time taken by existing technologies in half.
The company has ambitions of setting up ultra-fast charging stations across the globe, with plans of redefining the usage of batteries within automobiles.
With future ambitions of deploying around 1000 ultra-fast charging stationed by 2025, Exponent Energy promises to change the infrastructure dynamic in India. Their charge camps would be able to provide 1 MW of power to commercial EVs which would allow for a 15-minute charging window.
The startup, founded in 2020 by ex-Ather executives Arun Vinayak and Sanjay Byalal Jagannath, has built an ecosystem enabling ultra-fast charging for commercial EVs.
How Exponent’s Technology Works
Exponent’s innovation lies in its proprietary Battery Management System (BMS) 2.0, which reduces lithium plating by 87% through real-time cell monitoring. Its predictive thermal control system uses water-based cooling to maintain battery temperatures between 25-40°C. The company’s charging stations can deliver 1MW of power, supporting 41 daily charging sessions per station in Bengaluru trials.
Focusing on commercial vehicles, Exponent has partnered with Altigreen Propulsion Labs, deploying over 200 three-wheelers that have covered more than 1 million km.
With ₹380.72 crore in funding, including a Series B round led by Lightspeed, Exponent aims to deploy 1,000 charging stations and support 25,000 EVs by 2025.
Competitive Edge Over Global Players
Unlike BYD, which uses custom LFP chemistry and a high-voltage 1000V architecture, Exponent focuses on cost-effective standard LFP cells, achieving 92% component localization. Its charging stations cost significantly less, making its model ideal for emerging markets.
With expansion into Delhi-NCR, Mumbai, and Chennai planned by Q2 2025, Exponent is shaping the future of EV adoption in India and beyond.
