Abstract
There is provided an electric power supply system comprising a secondary battery unit which stores electric power generated by a solar cell module, a charge switch circuit which disconnects and connects a charge path between the solar cell module and the secondary battery unit, and a charge and discharge control unit which controls the disconnection and the connection of the charge path by the charge switch circuit, wherein, in the charge switch circuit, the disconnection and the connection of the charge path is controlled by an output voltage of the solar cell module when the charge switch circuit cannot be controlled by the charge and discharge control unit.
