本发明系一种电源管理设备及具备此电源管理设备之工作机械，其中，提供可效率佳接断对于电动部之电源的供给之电源管理设备及具备此电源管理设备之工作机械。电源管理设备(101)系检测出控制进程之待机指令，依据检测出之待机指令，以此待机指令比较在成为待机对象之各控制系统之待机间的电动部之作动时间。接着，电源管理设备(101)系将对于属于待机间之电动部之作动时间成为最大之控制系统以外之控制系统的电动部之电源的供给，于在各控制系统之控制结束后进行遮断，在各控制系统之待机结束时，再开始电源之供给。

The present invention provides a power-supply management device that can efficiently connect and disconnect the supply of power to electrically powered parts, and a machine tool provided with said power-supply management device. The power-supply management device (101) detects a wait command in a control program, and, on the basis of the detected wait command, compares the operation time of each electrically powered part during the wait period in each control system that is subject to waiting according to said wait command. Then, after the control systems have terminated control, the power-supply management device (101) disconnects the supply of power to the electrically powered parts that belong to the control systems other than the control system in which the operation time of the electrically powered part during the wait period is the longest, and then resumes the supply of power when the control systems finish waiting.
