IIT Researchers have developed a new Charging Technology that costs Half the current one!

Researchers from a number of IITs have developed a novel charging technique for electric cars that is approximately half the price of current on-board charger technology and may assist in significantly lowering the cost of two- and four-wheeled electric vehicles. The team claims that laboratory-scale development has been already completed at the Indian Institute of Technology (BHU), and that up-gradation & commercialization are currently underway.

According to the team, one of the country’s main electric vehicle makers has expressed interest in this new technique and is ready to build a completely commercial product that can be applied to existing EVs. IIT (BHU) Varanasi developed this technology in partnership with researchers from IIT Bhubaneswar and IIT Guwahati.

The rising prices of petrol and diesel in the country is worrisome for the common man. Amidst the rising cost of petroleum products and rising pollution levels, electric vehicles (EVs) are the best alternative to conventional IC engines but lack of high power off-board charging infrastructure forces automakers to incorporate onboard chargers into the vehicle itself.

said Rajeev Kumar Singh, Chief Project Investigator at IIT BHU.

Rajeev Kumar Singh told PTI (Press Trust of India):

The vehicle owner can charge the vehicles through the outlet and hence, this leads EVs to become very expensive. In the proposed onboard charger technology, we are reducing one additional power electronics interface required for propulsion mode and, therefore, the components involved are reduced by 50 percent. The proposed charger is reconfigurable that can act as a charger for charging mode and inverter for propulsion mode.

According to Singh, the cost of an onboard charger will be decreased by about 40-50 percent as a result of this technology when compared to the current charger.

The cost reduction in the charger will subsequently reduce the cost of the electric vehicle as well. In this way, the proposed technology is giving low-cost technology for electric vehicles. The technology will be completely indigenous and will have a significant impact on driving electric vehicles on Indian roads in a big way.

Rajeev Kumar Singh said.

The techno-commercial, economic, social, and environmental impacts of this technology, according to Pramod Kumar Jain (Director of IIT BHU), will all be beneficial.
