Abstract
A power control device includes a relay switch, a controller, a sensor and a battery controller. The relay switch is configured to turn electricity on and off between a battery for supplying a load with electric power and the load. The controller predicts load power characteristics indicating characteristics of power consumed by the load over time, and predicts, based on the predicted load power characteristics, charge/discharge power characteristics indicating characteristics of charge/discharge power of the battery over time. The sensor detects voltage between the terminals of the battery. The controller specify a voltage detection period from the charge/discharge power characteristics that was predicted, over which the charge/discharge power of the battery is equal to or less than a prescribed power over a prescribed period. The battery controller turns off the relay switch and detects the voltage between the battery terminals during the voltage detection period.
