Abstract: The present invention provides a state monitoring device which make it possible to certainly deliver, to the maintenance staff side, state monitoring information of an apparatus to be monitored which is disposed in a distant place with a bad communication environment. A state monitoring device 300 is provided with a communication unit 301 which performs communication using a first communication line for transmitting operating information of an apparatus to be monitored to a server device, and a second communication line for transmitting the operating information to the server device via wireless communication provided by a mobile object if the first communication line is not communicable.

Abstract: A control device of the present invention includes: an OCV estimating unit that estimates, based on a voltage value and a current value of a controlled device, an OCV of the controlled device; a capacity calculating unit that calculates an integrated capacity of the controlled device based on the current value of the controlled device; and a control unit that controls discharging and charging of the controlled device, and calculates a full capacity of the controlled device based on: a first SOC and a second SOC at a predetermined first OCV and a predetermined second OCV during the discharging or the charging of the controlled device; a first integrated capacity and a second integrated capacity at the first OCV and the second OCV during the discharging; and a third integrated capacity and a fourth integrated capacity at the second OCV and the first OCV during the charging.
