Nowadays, technology has always proven that it can improve quality of life as it brings conveniences and cut down manpower. To be able to improve standard of living in this environment to cope with the general population, development extent doesn’t seem to stop but to advancing continually. Capacitor is widely used for many electronic and electrical appliances, mostly used for smoothing the output and hold charges for further use by discharging its energy when it is disconnected from charging circuit but the storage capacity is comparatively low. Supercapacitor is then invented and it holds charge at a higher capacity and provides fast charging and discharge compared to rechargeable battery. This could be implemented in a vehicle as an additional energy storage, instead of the Lead-Acid battery alone, this will reduce the energy usage by the Lead-Acid battery, thus improving the battery’s life cycle. Electric cars use the combination of battery, regenerative braking, energy storage system as a fundamental component of Hybrid Energy Storage System (HESS) to increase the life cycle of battery while improving the reliability and efficiency of a system. In this final year project, instead of the implementation of regenerative braking to store energy, energy harvester such as Piezoelectric and Solar Panel is used as the input energy source, energy storage system using supercapacitor and also energy management system to distribute energy depending on the threshold State of Charge (SOC) of the battery and supercapacitor, thus improving the life cycle of battery and reliability. In this final year project, piezoelectric and solar panel will be implemented as an additional power source to a vehicle for startup purpose by designing an energy storage system that will distribute stored energy to vehicle depending on the criteria of battery voltage level and supercapacitor voltage level for reducing peak demand of battery while improving its life cycle. Moreover, this final year project implements purely software simulation by using MATLAB/Simulink to construct the simulation model for this HESS.
