Exponent Energy enters retrofit business with ‘Exponent Oto’

Energy-tech startup Exponent Energy has entered the retrofit segment with the launch of ‘Exponent Oto’, a rapid-charging retrofit solution that converts internal combustion engine (ICE) three-wheelers running on CNG and LPG into electric vehicles.

How does the retrofit process work?

In a 24-hour process, all engine-related components such as the engine block, gearbox, fuel tank, and exhaust, are removed and replaced with Exponent’s Piccolo battery pack, CX1 e^port, motor, and drivetrain.

The CX1 e^port is a rapid-charging interface.

Retrofitted autos can charge fully in 15 minutes, offer a range of 140–150 km and accelerate from 0–30 km/h in under 4.5 seconds.

Exponent also promises zero down payment, flexible EMIs, an assured buyback after three years and savings of up to Rs 5,000 a month compared to CNG or LPG vehicles.

Why is retrofitting important?

CEO and co-founder Arun Vinayak said retrofitting helps speed up EV adoption since vehicles already on the road far outnumber new ones. “The idea is to make great tech accessible and affordable to every driver,” he said.

Exponent operates in Delhi-NCR, Bengaluru, Chennai and Ahmedabad, with more than 2,100 EVs using its tech and over 150 charging stations.

The company has raised $44.6 million from investors including Lightspeed, Eight Roads Ventures, 3one4 Capital, and Hero MotoCorp’s family office.
