Abstract: The present invention provides a storage-battery control device 1 capable of enhancing economical efficiency by controlling charge state of a storage battery 12 so that surplus power generated by photovoltaic generation can be entirely charged into the storage battery 12 even in a case where power cannot be sold to a system power supply 50. A storage-battery control device 1 according to the present invention includes a load-power prediction device 4 to predict load power, a PV-power prediction device 3 to predict generated power by photovoltaic power generation, and a system controller 2 to obtain a predicted charge amount that is calculated by subtracting the generated power amount being a summation of the generated power in a prediction segment 60 having a start point set at a predetermined time, from the load power amount being a summation of the load power in the prediction segment 60, and when the predicted charge amount is positive, to control the charge state of a storage battery 12 at the start point so that the predicted charge amount can be charged in the prediction segment 60, wherein an end point of the prediction segment 60 is a time at which the generated power by photovoltaic power generation is predicted to become equal to the load power after reaching the maximum value of the generated power.
