A charge control device capable of efficiently equalizing the remaining capacity of each storage cell included in a storage battery is provided. A charge control device for a storage battery supplies power obtained by a solar battery to a storage battery having a plurality of storage cells connected in series to charge any of the plurality of storage cells. The charge control device includes: a cell voltage detection unit that detects each cell voltage of a plurality of storage cells; a switch group that includes a plurality of switches that are respectively connected between the plurality of storage cells; and detection by the cell voltage detection unit Based on the results, the storage cell having the lowest cell voltage among the plurality of storage cells of the storage battery is specified, and each switch of the switch group is individually controlled to be turned on / off, and the charging path from the solar battery to the specified storage cell And a charge control unit that forms [Selection] Figure 1 |
