ABSTRACT:
A charge control circuit has an excess charge detecting circuit for preventing the excess charge of a secondary battery responsive to the voltage of the secondary battery, and a switching circuit responsive to the output of the excess charge detecting circuit. The switching circuit and the excess charge detecting circuit are operated by the electromotive force of a solar cell without the power dissipation of the secondary battery.
