The integration of renewable energy resources with a UAV storage device is an important part for energy challenges that the world is facing now a days. With rapid investigation and development of electric energy storage devices in the world there is a growing interest to integrating both electrical energy storage devices and renewable energy resources into an integrated power system to improve their reliability and economy. This paper describes a hybrid battery charging system also describe the charging process with time for therechargeable battery. The design and implemented in this paper paves way to effectively and efficiently co-ordinate the utilization of renewable energy supply to charge a battery and reduce the charging time for the battery. Here The charging circuit that used to integrate the renewable energy resources with the electrical storage device system is based on the electronic amplifier and this is works based on comparator IC1 (LM741)to monitor the battery voltage level, also it can cut the charging current when the battery is charged full. This is based on comparing the battery voltage with another fixed potential. When the battery voltage is reached to a limit level during the charging process. Therefore, the comparator output is able to pass the currentto the relay and cutoff the charging voltage of the circuit. When the battery voltage become at certain level that is selected by variable resistance, the relay is connected in response to the comparator and charging the battery.
