IIT BHU scientists slash cost of onboard Electric Vehicle charger

Varanasi, January 24 2022:  Scientists of IIT (BHU) Varanasi have developed a new technology for charging Electric Vehicles which costs about half of the current on-board charger technology.
Says Dr. Rajeev Kumar Singh, Associate Professor and Chief Project Investigator of the Department of Electrical Engineering: “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. The vehicle owner can charge the vehicles through the outlet and hence, this makes  electric vehicles become very expensive.”
Tthe new technology developed in the institute, the cost of on-board charger can be reduced by about 50. Lab scale development has already been done at IIT (BHU) and upgradation and commercialization is in progress. The country's leading electric vehicle manufacturer 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. Experts from IIT Guwahati and IIT Bhubaneswar have also collaborated for this technology development. Electric vehicles will be accessible to the general public.
This research is  supported by the Ministry of Electronics and Information Technology (MeitY), Government of India.
Added Director of the Institute Prof. Pramod Kumar Jain: “The developed technology will help in the production of low-cost electric vehicles which will be beneficial for the common man. The technology will improve charging infrastructure and support the government's mission to bring electric vehicles on Indian roads in a big way.”
He said  a few projects on developing autonomous vehicles, connected vehicles are already underway with IIT (BHU) Varanasi. One such project is Averera project which has already won first prize globally in the Shell Eco Marathon last year. He further said that the IIT (BHU) Varanasi is planning to set up an interdisciplinary Centre on EV technologies to carry out design, fabrication, and testing of battery management systems, commercialize research, provide solutions to R&D problems and develop human resources in this area.”
