The battery capacity of a storage battery is estimated without acquiring information on the battery capacity from the storage battery side. A battery capacity estimation device that estimates the battery capacity of a storage battery, the battery capacity estimation device including: a characteristic information acquisition unit configured to acquire the charge characteristic information of the storage battery in which at least one of a charge current, a charge voltage, or a charge power for charging the storage battery is associated with the battery capacity; and a capacity estimation unit configured to perform an estimation process of outputting power of a first output power value to the storage battery over a predetermined time necessary for estimating the battery capacity to perform first charging and estimating the battery capacity on the basis of at least the first output power value.
