Abstract

Regenerative Braking System (RBS) is an efficient system to reduce vehicle emission and fuel consumption. RBS is a system which converts mechanical energy to electrical energy during braking action. It will become an important system for future vehicle such as hybrid and electric car. This study will start with literature review about the Regenerative Braking System (RBS). The basic design and components used in the regenerative braking for current vehicles will also be reviewed. Through the study, a RBS model can be design or develop for future study. The working mechanism was studied to understand how the RBS could convert mechanical energy to electrical energy. The important components used in RBS will be determined such as electric motor, motor controller and battery. To produce a RBS model, an e-bike conversion kit has been bought from Hong Kong and an alternator was selected to be installed in the bicycle. The results and calculations show that both devices can function properly, that means both devices can form recovery energy to charge battery during braking. During the recovery energy working, brake effects are formed to decelerate the bike. The recovery energy during braking for both devices are taken and compared to found out which one can produce high recovery energy during braking. In addition this RBS model can be used for future study.
