One of the country’s leading electric vehicle manufacturers has also shown interest in this new technology and is ready to develop a full-fledged commercial product that can be applied to existing electric vehicles
A new technology has been developed by researchers from various IITs for charging Electric Vehicles (EVs) which costs about half of the current on-board charger technology and can help to significantly reduce the cost of two-and-four-wheeler EVs.
The lab scale development has already been done at IIT (BHU) and up-gradation and commercialisation was in progress, according to the team.
One of the country’s leading electric vehicle manufacturers has also shown interest in this new technology and is ready to develop a full-fledged commercial product that can be applied to existing electric vehicles, the team claimed without revealing the name of the company.
In collaboration with experts from IIT Guwahati and IIT Bhubaneshwar, the technology has been developed at IIT (BHU), Varanasi.
“The rising prices of petrol and diesel in the country are 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 on-board chargers into the vehicle itself”, said Rajeev Kumar Singh, Chief Project Investigator, IIT BHU.
“The vehicle owner can charge the vehicles through the outlet and hence, this leads electric vehicles become very expensive. In the proposed on-board charger technology, we are reducing one additional power electronics interface required for propulsion mode and, therefore, the components involved are reduced by 50 pc. The proposed charger is reconfigurable that can act as a charger for charging mode and inverter for propulsion mode”, he told PTI.
Singh explained that because of this, the cost of the on-board charger will be reduced by almost 40-50 pc in comparison with the existing one.
“The cost reduction in the charger will subsequently reduce the cost of the EV as well. In this way, the proposed technology is giving low cost technology for EVs”.
“The technology will be completely indigenous and will have a significant impact on driving electric vehicles on Indian roads in a big way”, he said.
The techno-commercial, social, economic and environmental impact of technology will also be positive, said Pramod Kumar Jain, Director of IIT BHU.
“The will improve charging infrastructure and support the government’s mission to bring electric vehicles on Indian roads”, he said.
