Abstract: The present disclosure provides a work machine management system that can predict the maintenance timing of a work machine with higher accuracy than conventional techniques. A work machine management system 100 of the present disclosure includes an input/output unit 121 and a processing unit 122. The input/output unit 121 receives from work machines 200 positional information PI and operation information OI on the work machines 200, and also receives from a geographical information system server 300 geological information GI on an area where the work machines 200 are to perform an operation, based on the positional information PI. The processing unit 122 predicts the maintenance timing of each work machine 200 based on the operation information OI and the geological information GI.

Abstract: An electronic control unit includes a first controller, a second controller, and a determination portion. The first controller includes a first control portion that determines whether or not supply of power from a battery to the first controller is interruptible. The second controller includes a regulator that regulates power supplied from the battery to the first controller and a second control portion that controls the regulator. The determination portion determines whether or not the supply of power is forcibly interruptible even when the first control portion does not determine that the supply of power is interruptible. When the determination portion determines that the supply of power is forcibly interruptible, the second control portion controls the regulator to interrupt the supply of power from the battery to the first controller.
