Exponent Energy announced a 1.5MW rapid charging technology.
It also announced a 1MW rapid charging system for electric buses.
The 1MW charging system will launch in the next six months.
Initially, the 1MW charger will be exclusive to Veera Vahana fleet.
Other bus manufacturers will get access to the 1MW charger later.
The company has developed a complete charging ecosystem: e^pack (battery pack), e^pump (charging station), and e^plug (charging connector).
Its technology enables a 15-minute rapid charge with a 3,000-cycle life warranty using standard lithium-ion cells.

CEO Arun Vinayak said India has an opportunity to lead in EV technology.
BYD's 1MW Super e-Platform in China allows a 400 km range in 5 minutes.
BYD holds nearly 15% of the Chinese EV market, while Tesla's share slipped to 10.4%.
Tesla sales in China fell for five consecutive months year-on-year; February sales plunged 49%.
Tesla sales in Germany dropped 76% last month amid protests against CEO Elon Musk.

Exponent Energy builds a complete rapid charging ecosystem for electric vehicles.
Its technology enables a 15-minute rapid charge with a 3,000-cycle life warranty using standard lithium-ion cells.
Over 1,700 EVs are powered by Exponent's technology across India.
Over 3.5 lakh (350,000) rapid charging sessions have been completed.
Exponent-powered EVs have covered 20 lakh kilometres.
The company has expanded to five cities: Delhi NCR, Chennai, Ahmedabad, Kolkata, Hyderabad.
The 1MW charging for buses can reduce capital cost of electric buses by 30-40% by enabling smaller batteries (250 km range vs 400 km).
Lower capital costs are expected to reduce passenger fares.
