ACTUAL MACHINE MANAGEMENT DEVICE, AND ACTUAL MACHINE MANAGEMENT SYSTEM

The present invention is capable of, even when a plurality of work machines 400 and 500 are remotely operated, knowing the remaining amount of power storage of the each of the standby work machines 400 and 500, and appropriately managing the power storage amount of power storage devices 440 and 540. An actual machine management device 300 configured to manage a plurality of work machines 400, 500 to be remotely operated, each work machine including a power storage device 440, 540 and a communication device 421, 521 capable of transmitting power storage information regarding the remaining amount of power storage of the power storage device 440, 540, the actual machine management device 300 configured to, based on the power storage information transmitted from each communication devices 421, 521 of the standby work machines 400, 500 in a standby state and not actuated by remote operation among the plurality of work machines 400, 500, transmit the power storage information to notification devices 221, 225 at timing of notification about the remaining amount of power storage of the power storage devices 440, 540, the timing being a time when for each of the standby work machines 400, 500 the remaining amount of power storage of the power storage device reaches or estimated to reach a predefined power storage threshold.
