Electric drive for blender drum

The invention relates to an electric drive for a blender drum, comprising a high-voltage DC power supply (HVN) to which at least one battery (B), a converter (SR) and at least one interface (IF) for connecting a stationary power supply are connected, the at least one battery (B) being charged solely via at least one external interface, a controller (eDCU) being provided, the controller controls energy flow from and to components coupled to the high voltage DC power grid (HVN). The invention further relates to a corresponding method for operating such an electric drive. 本发明涉及一种用于搅拌器滚筒的电驱动器，电驱动器具有高压直流电网(HVN)，至少一个电池(B)、变流器(SR)和用于联接固定电源的至少一个接口(IF)联接至该高压直流电网，其中，至少一个电池(B)仅通过至少一个外部接口来充电，其中，设置有控制器(eDCU)，控制器控制来自联接至高压直流电网(HVN)的部件和去往联接至高压直流电网(HVN)的部件的能量流。此外，还提出了一种相应的用于运行这种电驱动器的方法。
