Optimum Sizing of Hybrid Energy Storage System for an Electric Motorcycle Masoud Masih-Tehrani

In this research, the number of battery replacement during 10-years working time of e-motorcycle is concerned instead of the initial energy storage system price. The 10-years equivalent price of energy storage system is defined as initial price and the replaced battery prices during 10-years. The life model of battery is necessary for determination of the number of battery replacements during 10-years. The existence of UC in HESS improves the power specification, which increases acceleration performance and regenerative braking capacity. This moderates battery current and rises battery lifetime. In addition, the number of required battery replacements is decreased and the 10-years equivalent price of energy storage system will be reduced. The results show the optimum sized HESS has very good power specification. The 10-years equivalent price of HESS is about 3400 $ lower than conventional ESS price, while the initial price of HESS is about 840 $ higher.
