The present invention comprises: switching means connected between a battery 13 for supplying electric power to a load 4 and the load 4, the switching means switching between turning electricity on and off; predicting means for predicting load power characteristics indicating characteristics of electric power consumed by the load 4 over time, and for predicting, based on the predicted load power characteristics, charge/discharge power characteristics indicating characteristics of the charge/discharge power of the battery 13 over time; detecting means for detecting the open-circuit voltage of the battery 4; and control means for controlling the switching means. The control means specifies, as a voltage detection period, a period over which the charge/discharge power of the battery 13 from the charge/discharge power characteristics predicted by the predicting means is equal to or less than a prescribed power over a prescribed period, and turns off the switching means and detects the open-circuit voltage during the voltage detection period.
