APPARATUS FOR CONTROLLING SOLAR CHARGING AND METHOD THEREFOR
First Claim
1. An apparatus for controlling solar charging, the apparatus comprising:
- a main controller controlling charge/discharge operations of a battery storing power generated in a solar cell in order to protect overcharge and overdischarge of the battery; and
a secondary controller maintaining a sleep mode when a terminal voltage of the battery is not less than a threshold voltage and reviving the main controller by using power generated in the solar cell when the terminal voltage of the battery is less than the threshold voltage.

Abstract
Disclosed are solar charging control apparatuses and methods for the same. An apparatus for controlling solar power charging may comprise a main controller controlling charge/discharge of a battery storing power generated in a solar cell in order to protect overcharge and overdischarge of the battery; and a secondary controller maintaining a sleep mode when a terminal voltage of the battery is not less than a threshold voltage and reviving the main controller by using power generated in the solar cell when the terminal voltage of the battery is less than the threshold voltage. Therefore, even when the main controller of the solar charging control apparatus is downed, the solar charging control apparatus can be ordinarily operated by using solar energy generation. Also, costs demanded for managing a solar charging system which is installed in a remote place can be saved.

6. A method for controlling a streetlamp system using solar charging, the streetlamp system comprising a main controller, a secondary controller, a battery, and a solar cell,
wherein, when a terminal voltage of the battery is less than a threshold voltage and the main controller is downed, the secondary controller is operated by using power generated in the solar cell and revives the main controller so that the main controller controls the streetlamp system.
