Short Description:

Energy-tech startup Exponent Energy has introduced 'Exponent Oto', a rapid-charging retrofit solution that converts internal combustion engine (ICE) three-wheelers running on CNG and LPG into electric vehicles. The 24-hour conversion process replaces engine components with Exponent's battery, motor, and charging interface. These retrofitted vehicles offer a 140-150 km range, a 15-minute full charge, and potential monthly savings of up to Rs 5,000.

Detailed Coverage:

Exponent Energy, an energy-tech startup, has entered the vehicle retrofit market with the launch of 'Exponent Oto'. This innovative solution is designed to convert existing internal combustion engine (ICE) three-wheelers, currently powered by compressed natural gas (CNG) and liquefied petroleum gas (LPG), into fully electric vehicles (EVs).

The conversion process is completed within 24 hours. It involves removing all engine-related parts, including the engine block, gearbox, fuel tank, and exhaust system. These are then replaced with Exponent's proprietary technology: the Piccolo battery pack, the CX1 e^port rapid-charging interface, an electric motor, and the necessary drivetrain.

The 'CX1 e^port' interface allows for rapid charging, enabling retrofitted vehicles to achieve a full charge in just 15 minutes. Once charged, these electric three-wheelers can travel between 140 to 150 km on a single charge. They also demonstrate quick performance, accelerating from 0 to 30 km/h in under 4.5 seconds.

Exponent Energy is also providing attractive financial incentives to drivers, including options for zero down payment, flexible Equated Monthly Installments (EMIs), an assured buyback after three years, and projected savings of up to Rs 5,000 per month compared to operating vehicles on CNG or LPG.

Impact This initiative has a significant potential impact on accelerating EV adoption in India, particularly within the commercial three-wheeler segment. By offering a cost-effective and faster route to electrification than purchasing new EVs, Exponent could unlock a vast market of existing vehicles, thereby contributing to reduced emissions and lower operating costs for drivers. The company is already operating in Delhi-NCR, Bengaluru, Chennai, and Ahmedabad, with over 2,100 EVs using its technology and more than 150 charging stations. Exponent has secured $44.6 million in funding from investors including Lightspeed, Eight Roads Ventures, 3one4 Capital, and Hero MotoCorp's family office. Impact Rating: 7/10
