Hybrid Electric Bicycle with Regeneration Capability

Abstract

This paper presents a method to make a hybrid electric bicycle by modifying the existing conventional bicycle keeping the ability to pedal. The cycle consists of a battery, motor drive, which comprises a DC–DC converter for the motor, as well as regenerative braking. This cycle has a unique feature of exercise mode where the user can charge the battery as in stationary cycles in the gymnasium. The bicycle covers 28 km with a maximum speed of 23 km/h. In one charge which is sufficient from a city point of view, where pollution and traffic congestion is a significant concern these days. This paper also presents mechanical designs, electronics design of DC–DC converter, power supply, and a microcontroller with test results.
