The invention relates to a method for operating an electric drive train (11) of a work machine (10), the drive train (11) comprising a work drive (20) having a hydraulic work device (22) and an electric work motor (21) and a travel drive (30) having an electric travel motor (31), the operation of the work drive (20) being carried out independently of the operation of the travel drive (30) (100). The method according to the invention is characterized in that the power required by the working drive (20) is provided (100, 106) taking into account the efficiency of the working motor (21) and the efficiency of the working device (22). The invention also relates to a corresponding electric drive train (11) and to a corresponding work machine (10).

    本发明涉及一种用于运行作业机械(10)的电的驱动系(11)的方法,其中,驱动系(11)包括具有液压的作业装置(22)和电的作业马达(21)的作业驱动器(20)以及包括具有电的行驶马达(31)的行驶驱动器(30),其中,作业驱动器(20)的运行以独立于行驶驱动器(30)的运行的方式进行(100)。按本发明的方法的特征在于,在考虑到作业马达(21)的效率和作业装置(22)的效率的情况下提供(100、106)作业驱动器(20)所要求的功率。本发明还涉及一种对应的电的驱动系(11)和一种对应的作业机械(10)。
