Abstract (en)
[origin: WO2021259703A1] The invention relates to a method for operating an electric powertrain (11) for a working machine (10), the powertrain (11) comprising a working drive (20) with a hydraulic working device (22) and an electric drive motor (21) as well as a drive system (30) with an electric drive motor (31), wherein the operation of the working drive (20) is carried out (100) independently from an operation of the drive system (30). The method according to the invention is characterized in that a power requested from the working drive (20) is provided (100,106) taking into account an efficiency of the drive motor (21) and an efficiency of the working device (22). The invention further relates to a corresponding electric powertrain (11) and a corresponding working machine (10).
