There are several constraints when using a battery powered energy storage system namely: low power density and a considerably short cycle life. Battery has high specific energy but low cyclic rate and long recharge time. Supercapacitors, on the other hand; is characterized by their extremely fast charge and discharge capability, high current delivery in very short time, high charge-discharge cycle, high power density but relative low energy density. Most energy storage system of today relies fully on one single type of battery. Every different type of battery has its own limitations. Hence, subjecting the battery to large fluctuating loads introduce unwanted stresses which shorten the battery operational lifespan. In this work, a hybrid energy storage system (HESS) using battery technology and supercapacitors technology will be investigated with the aim to improve the constraints and limitations of the conventional battery energy storage system. The major challenges of the hybrid energy storage system such as mismatch in voltage, current, charge-discharge rate, charging time of the different energy storage system to function as a single system are to be investigated and addressed in this research. An embedded system with decision making algorithm is design to manage the energy flow, with utmost priority at safety and operation lifetime. A switching-based hybrid energy storage system is designed and developed to eliminate the need of DC-DC converters. The long-term operational reliability of this switching-based HESS is studied to maximise the interest of the HESS. A complete design and development practice for the HESS is discussed. In order to ensure the supercapacitors and batteries are capable to supply sufficient energy and power to the load operational demand, a sizing methodology for the developed HESS is developed. Finally, a protection system for the developed HESS is also designed and tested to improve the reliability of the system. 2022-11 Thesis http://shdl.mmu.edu.my/11851/ http://erep.mmu.edu.my/ masters Multimedia University Faculty of Engineering (FOE) EREP ID: 11562
