In the current study, the performance characteristics of symmetric super-capacitor (SC) utilizing activated carbon electrodes have been analyzed in an aqueous 1M potassium hydroxide (KOH) solution implemented as the electrolyte. Activated carbon (AC) is derived from Chitosan (CS), which possesses remarkable biodegradable characteristics via the chemical activation method at N2 atmosphere conditions using ZnCl2 as activating agent. To evaluate how CS performs at various activation temperatures of 500, 600, and 700°C, the experiment was conducted. The effect on activation temperature here on po...

This paper proposes a method for battery storage and supercapacitor (SC) hybrid operation toward improving EVs' performance. The adopted concept is established to regulate the level of charge for the SC to suit the immediate storage needs of the EV in such a way as to couple both storage devices. The results demonstrate that the current drawn from the battery has significantly reduced the discharging rate of the battery smoothed out compared to the EV without the SC. Also, the electric vehicle (EV) battery capacity is improved and the implementation of an SC eliminates the abrupt discharg...
