Abstract

Cycling nowadays is not only a means of transport. Technology in bicycle making has rapidly evolves that the it is now a multimillion industry and the price of bicycle used for casual exercise during weekends can easily reached up to thousands of ringgit. Cycling normally involves transfer of kinetic energy from human to the bicycle through several mechanical parts and elements. However, the produced kinetic energy usually goes to waste apart from moving the bicycle forward. Therefore, this project aims to develop an energy storage system that can store the energy produced during the cycling activity to be used for charging of electrical appliances such as mobile phone afterwards. In order to achieve the relevant objective, two methods are used in this project for the battery charging method. Some other methods are also used such as the trial method to try the suitability of the method to charge the battery. The methods used are to use a dynamo as an AC generator and a DC machine as a DC generator. These two types of generators have different sizes in terms of diameter where they require different speeds to reach the required RPM. The dynamo needs more cycling energy to reach the same RPM as the DC generator because of its smaller diameter compared to the DC generator. Through the accumulated results and the analysis done, the prediction of the required voltage can be obtained through a linear equation resulting from the graph of the resulting voltage against RPM. As the conclusion, it is expected that this project can be carried out outside of this project and mounted on a bicycle for daily use in the future.
