Energytech startup Exponent Energy opens first store in Bengaluru to sell and retrofit EV three-wheelers

Energytech startup Exponent Energy has opened its first Exponent Sales Point (ESP) Store in Laggere, Bengaluru.

The outlet will showcase the full range of Exponent-enabled three-wheelers and serve as a one-stop destination for customers. The store will also operate as a retrofit touchpoint for converting existing CNG/LPG passenger three-wheelers into electric vehicles.

The startup said the store creates a direct and convenient access point for auto drivers to explore Exponent-enabled vehicles, experience 15-minute rapid charging, understand the retrofit process, and take test drives. It now aims to add up to 15+ touchpoints across the city by the end of FY26.

To date, Exponent has launched 5 three-wheelers in partnership with leading OEMs such as Montra Electric (the Murugappa Group), Kinetic Green, and others. The store brings all Exponent-enabled models under one roof, allowing customers to explore and purchase with easy financing options and minimal documentation. Every vehicle comes with a five-year warranty or 3,000 charging cycles. With 0-100% 15-minute rapid charging and access to Exponent’s 70+ charging points across Bengaluru, the company aims to make the shift to electric practical and hassle-free.

Ayush Bhargava, Head of Business, Exponent Energy, said, “Our first ESP store gives drivers a firsthand experience of the full Exponent ecosystem, from exploring our range of Exponent-enabled vehicles to seeing how existing vehicles can be upgraded. This is a buying experience auto drivers have never had before, combining clarity, choice and convenience under one roof. With this store, we are setting the foundation for a faster, more accessible EV transition and plan to replicate this model across more cities soon. When drivers see how easily they can switch to EVs at lower running costs, the shift becomes inevitable.”

In November 2025, Exponent Energy also entered into the EV retrofit business with its newly launched retrofit technology, Exponent Oto, capable of converting any CNG or LPG auto into an electric vehicle in just 24 hours. Exponent Oto allows drivers to save up to Rs 5,000 every month, even after accounting for charging and EMI costs.

Founded in 2020 by ex-Ather executives Arun Vinayak and Sanjay Byalal, the startup has worked on their battery pack (e^pack), charging station (e^pump), and charging connector (e^plug) that together unlock a 15-minute rapid charge and give a 3,000 cycle life warranty for EVs (a new industry standard)—all done on a range of affordable Li-ion cells.

Exponent has so far raised a total of $44.6 million from investors, including Lightspeed, Eight Roads Ventures, YourNest VC, 3one4 Capital, AdvantEdge VC, and the family office of Dr. Pawan Munjal, Chairman & CEO of Hero MotoCorp.
