The new retrofit EV tech will initially be available for passenger three-wheelers that currently run on CNG and LPG platforms.
India, November 7, 2025: Exponent Energy, a Bengaluru-based energy-tech company, has launched its ‘Exponent Oto’ technology to retrofit ICE three-wheelers into EVs with 15-minute rapid-charging batteries. Retrofitted CNG and LPG autorickshaws will be able to seamlessly integrate with Exponent’s proprietary energy ecosystem, charging from 0-100% in just 15 minutes at any Exponent e^pump (charging station).
The new retrofit EV technology is available for passenger three-wheelers currently running on CNG and LPG. The retrofit process takes just 24 hours, giving existing autos a fresh lease of life. Exponent Oto is backed by a warranty of 5 years or 3,000 charging cycles, giving drivers the peace of mind to confidently make a switch.
Retrofitting makes the EV transition more accessible to millions of drivers across India, accelerating the adoption of clean mobility. With zero downpayment, flexible EMI plans, and an assured buyback after three years, Exponent aims to make the shift to electric simple, affordable, and secure. Drivers will see an immediate savings of up to ₹5,000 every month, as the monthly charging costs and EMI combined will be lower than current monthly fuel and maintenance costs for CNG or LPG vehicles.
Vehicle conversion to EVs will also play a key part in meeting India’s EV penetration targets for 2030 , reducing carbon emissions, improving air quality across Indian cities and states, and strengthening the country’s energy security.
