Battery-operated vehicle part of engineering course project work

SANGAREDDY: The final year students (EEE) of DVR College of Engineering and Technology developed a low cost electric car that can accommodate two persons.

This was part of their project work in the final year to learn how electric cars if run on battery reduce pollution. Most of the students who participated in the project have a rural background.

Features

The salient features of the car are: torque speed -max 45 kmph, range 50 km per charge, vehicle weight – 150 kg, battery type – sealed, lead acid, battery- four batteries with 12 volts capacity, charging time: six to eight hours, cost per km. 70 paise, wheel base 10”X 3”.

“The most important feature of the car was that of having brushless DC motor (hub motor) which allows the motor to work with maximum capacity as it is fixed at the wheel base on the right side of the rear wheel” explain Swetha and Rajakumar, partners of the eight-member team. They incurred a cost of Rs. 60,000 on a single unit.

Metal body

“The body was fabricated with metal which weighs high. Had we used fibre the weight of the vehicle will much less thereby increasing fuel consumption as well as running capacity of the vehicle.” says E. Ramesh, another student.

The other members are Raghavendra, Kishore, Kiran, Prabhudas and Jatin. The project was supervised by Prof. A Sudarshan.

“The idea of the project report was to encourage students to express their creativity. This will help them at the post-graduation and research levels,” Prof. V. Laksmipathy, principal of DVR College told The Hindu.
