Five students design auto-rechargeable bike

Ramgarh: A five-member team of electrical engineering students in Ramgarh Engineering College located in Murubanda village under Chitarpur block has come up with a power saver and auto-rechargeable electric bike using an old motorcycle at an estimated cost of Rs 30,000.
Jai Kumar (23), a fourth-year student, said the team used two lithium ion batteries of 60 amp power that will automatically charge the vehicle while driving.
“We have connected dynamo and two lithium ion batteries with a wheel of the bike. Batteries start charging automatically when the wheel moves. The bike can run approximately 80km at a stretch,” he added.
Other team members in this innovation include Ajay Kumar, Vikram Soren, Amit Kumar Rajak and Kalipado Paramanik. They demonstrated their bike named ‘Stark Rider’ at the college.
Vice-principal of the college, Nazmul Islam, was also present.
Kumar said, “We have included a power-saving and an over-heating protection system in the bike. The performance of the bike can be extended to 300km at a stretch on installation of more powerful batteries and a dynamo.”
The vice-principal said Kumar and his team was assisted by head of the electrical engineering department Arunabha Datta.
