Battery is important for generating and storing electrical energy. It is sold at a rate of several billions of dollars per year worldwide. Battery can be found in nearly all motor vehicles, all types of portable electronic equipment, smoke alarms and others. However, it has a limited number of charge and discharge cycle because the process involves chemical substances. These chemical reactions have parasitic thermal release that cause battery to heat up and initiate unwanted reaction that could affect the batteries performance. With the emergence of technology, ultracapacitor is developing. Research has been proven that ultracapacitor have many advantages such as long life cycle, high charging and discharging rate, high capacitance in a small size and wide temperature range. However, people are not venture to looking and comparing the performance ofultracapacitor and battery at various temperatures. This project investigates the battery, ultracapacitor and battery-ultracapacitor (B-UC) combination performance at various temperatures. The main activity is to design the best equivalent circuit modes for battery standalone, ultracapacitor standalone and BUC combination to be tested at various temperatures. Throughout this project, a working prototype of operating circuit consisting of battery, ultracapacitor and the Light Emitting Diode (LED) as a load will be constructed. Data Studio software with combination of Science Workshop 750 interface is used to verify the graph of current and voltage produced in the equivalent circuit model. In this project, the finding in this research indicates the ultracapacitor standalone supersite the performance of battery standalone with regard when tested at various temperatures. iii
