Power Regeneration for BLDC Bicycle Motor

Abstract

The purpose of this project was to design and build an electric bike conversion system capable of self-charging. The inspiration for this project originated with the idea of further empowering those in Third World countries who are not able to afford expensive means of transportation. Bikes are the most affordable personal transportation and using the power regeneration system with an e-bike conversion system will allow the user to use the system as a whole without the need to connect to an electric grid for recharging of the e-bike’s batteries. We achieved this by using the e-bike’s brushless DC motor in connection with a rectifier, boost converter, and a recharging integrated circuit to monitor and control the output of the energy created from utilizing the motor as a generator.
