Abstract

As technology advances, batteries still remain as one of the most important power sources in the world. Batteries are widely used in electrical appliances because it is one of the best competent energy storage devices available today. However, batteries have limitations that need to be improved such as limited cycle life, high equivalent series resistance (ESR) and contribute to environmental issues. The project investigates the capability of the ultra-capacitor in an attempt to improve the current runtime of the battery for electrical appliances. The main activity of this project is to design a suitable equivalent circuit model for the battery/ultra-capacitor combination. Data Studio software with the combination of Science Workshop 750 interface is used to verify the graph of the peak current produced in the equivalent circuit model of the battery/ultracapacitor combination. The experiment is conducted using the breadboard and then the selected circuit equivalent circuit is constructed on the veroboard to make sure the components or hardware connected firmly. This model circuit of battery/ultra-capacitor combination is expected to increase the current runtime of the battery 3-15% compared to the conventional battery. The circuit also is applied to the vehicles such as motorcycle and car to improve the fuel consumption. The project has the potential in contributing to the environment, world economy, reduce the energy waste and improve the power source of the electrical appliances.
