15-minute fast-charging EV technology revealed by Exponent Energy in Bengaluru

 

With its battery management system and charger, Bengaluru-based startup Exponent Energy says that any vehicle can be fully charged in just 15 minutes. Exponent Energy has made public its proprietary fast-charging technology.

The startup outsources the manufacturing of the cells. It features a custom battery management system and its own distinctive battery pack design in place of specialized cells. The inclusion of an HVAC (heating, ventilation, and air-conditioning) system to prevent the cells from overheating is the main talking point, though. According to the manufacturer, after 3,000 rapid charging cycles, the battery pack only deteriorated by 13%, which is half the industry standard.

Instead of being an onboard component of the battery, the HVAC system is a component of the stationary charger. There is no substitute for rogers and portable chargers.

According to the company, its technique prevents the battery pack from deteriorating despite frequent quick charging by balancing the voltage supply using its custom software and circulating 10 degrees Celsius of cold water inside the (specially constructed) battery pack to cool the cells.

In Bengaluru, there are currently 30 charging stations, 20 of which are privately owned. In this calendar year, Exponent hopes to grow in Mumbai, Hyderabad, Ahmedabad, Delhi-NCR, and Chennai.

Chargers come in intracity and intercity sizes. Today, we had the opportunity to witness the intracity charger in operation as it quickly charged an electric three-8kWh wheeler’s battery.

The intercity charger is being developed, according to the business, and will be unveiled soon.

Earlier, In January 2023, Exponent Energy collaborated with Altigreen, a commercial electric vehicle manufacturer, and launched a new variant of its three-wheeler cargo EV, called neEV Tez. 

The neEV Tez features an 8.2kWh e^pack, a proprietary battery by Exponent built using regular LFP cell chemistry, that delivers a 98-km range and charges from 0% to 100% in 15 minutes at Exponent’s e^pump charging network
