Study of the Charging and Discharging of Supercapacitor with Battery by Using Photovoltaic Energy as a Power Source

Abstract

              The purpose of this study were to 1) study about how the supercapacitor and battery work when being charged and discharged, 2) analyze the supercapacitor and battery efficiency in relation to charge and discharge, and 3) determine the luminescent efficiency. The sample group was 75F, 15V, supercapacitor. The research instruments consisted of supercapacitor, lead-acid battery, solar cell, LED lamp, data logger. Arithmetic mean was utilized to analyze the data.

              The findings showed that 1) the supercapacitors and batteries can be charged at a high currents to modify their charge and discharge behavior. However; the voltage must not be higher than the rating. Changes in voltage and current are transient. The amount of current used determined how long it took to charge a capacitor. The time was taken to fully store energy decreases with increasing current, 2) the effectiveness of using batteries and supercapacitors together for charging and discharging was shown that charging time for super capacitors, batteries, and solar cells was spent two hours and forty-eight minutes. Additionally, the supercapacitors and batteries discharge energy to LED for eleven hours and thirteen minutes. Also, the SC connected batt's efficiency was 93.18 %, which can be illuminated batteries the university sign all night.
