With 15-Minute Rapid Charging Tech, Exponent Eyes Commercial EVs

Exponent Energy (Exponent), with its 15-minute rapid charging tech, aims to help the electric vehicle OEMs launch and sell economically priced electric vehicles. The startup says that its patented ‘water-based’ off-board thermal management system can charge an electric three-wheeler equipped with batteries provided by Exponent from 0 to 100% in 15 minutes

Also undergoing a trial with a major commercial bus manufacturer, the startup says it will launch the tech for electric bus OEMs soon. However, it has no immediate plans to venture into the two-wheeler segment, Arun Vinayak, Co-founder & CEO, told Electronics For You during an exclusive conversation. Once launched, the tech will charge electric buses from 0 to 100% in 15 minutes.

He says, “We don’t differentiate in vehicle forms from a technology point of view. The energy consumption by two-wheelers deployed in the logistics segment is much lesser than that consumed by three- and four-wheelers. The question we want to answer is not how many electric vehicles we are helping in charging rapidly, but how much energy we can save while doing the same.”

“Two years from now, we might enter the two-wheelers segment. But for now, we know that most Indian startups don’t die of starvation, but they die of indigestion,” he adds.
