The Energy Storage System (ESS) is an expensive component of an E-bike. The idea of Hybrid Energy Storage System (HESS), a combination between battery and Ultra-Capacitor (UC), can moderate the cost of E-bike ESS. In this paper, a cost function is developed to use for optimal sizing of a HESS. This cost function is consisted of the HESS (battery, U...

... BESS is the most matured and transformative technology in today's ESS industry market [2]. In microgrids, the BESS can be used for energy arbitrage, peak shaving, frequency regulation, voltage deviation, energy balance and reliability concerns in the presence of renewable energies [3]. However, the cost of BESS in the market is still a barrier for broad application [4]. ...
... As can be seen, the FC has the highest per unit size (kW) capital cost and the lowest lifetime. The efficiencies of FC and EL are considered as 50% and 90%, respectively [24], [15]. Battery's minimum and maximum state-of-charge (SOC) as well as round-trip efficiency are considered as 20%, 90%, and 95% respectively. ...
