This paper present experiment made to compare the charging and discharging capability between lithium-ion battery and super- capacitor for slow charge rate. The Lithium ion battery and super-capacitor were both discharge to 0% state of charge, SOC and charged up to 63% SOC. DC supply and photovoltaic solar panel as the power source for charging. The trends in charging characteristics for both energy storage devices were observed. It is observed that the super-capacitor can act an energy storage based on the charge and discharge pattern from the experiment.
