Abstract
A solar power system has a charging device. The charging device is powered by a solar cell to charge a battery pack having a secondary cell. The charging device has input voltage detection circuit that detects an input voltage from the solar cell; switching circuit that converts the input voltage to supply a charging current to the battery pack; charging current detection circuit that detects the charging current; and control circuit that controls the switching circuit to change the input voltage in order that a resultant charging current becomes suitable for charging the battery pack.
