The invention relates to a current distributor unit (1) for a commercial vehicle having at least one auxiliary drive with an electric machine (3), comprising: a first input (E1) for connecting to an energy store (2) of the commercial vehicle and providing a DC voltage; a second input (E2) for connection to an external current source; a first output (A1) for connection with an auxiliary driver; a second output (A2) for connection to an external current collector; and a third output (A3) for connection to a low-voltage on-board electrical system; a high-voltage distributor (6) which is connected to the first input (E1) and forms a connection between the energy store (2) and other components of the current distributor unit (1); a control unit (5) which monitors at least the high-voltage distributor (6) and can control components of the current distributor unit (1); at least one inverter (I1; i < 1.1 >; an inverter (I1, I2), which is arranged in a current path between the high-voltage distributor (6) and at least one of the terminals for the first output (A1), the second output (A2) or the second input (E2), a first converter (K1), the first converter is arranged between the high-voltage distributor (6) and the third output (A3) and converts the DC voltage provided by the high-voltage distributor (6) into a lower DC voltage. A further aspect of the invention is a vehicle having such a current distributor unit.
本发明涉及一种用于商用车辆的电流分配器单元(1),所述商用车辆具有至少一个带有电机(3)的辅助驱动器,所述电流分配器单元具有:用于与商用车辆的能量存储器(2)连接的提供直流电压的第一输入端(E1);用于连接于外部的电流源的第二输入端(E2);用于与辅助驱动器连接的第一输出端(A1);用于与外部的集电器连接的第二输出端(A2);和用于与低电压车载电网连接的第三输出端(A3);高压分配器(6),所述高压分配器与第一输入端(E1)连接并且形成能量存储器(2)和电流分配器单元(1)的其他部件之间的连接;控制单元(5),所述控制单元至少监控高压分配器(6)并可以控制电流分配器单元(1)的部件;至少一个逆变器(I1;I1.1;I2),所述逆变器设置在高压分配器(6)和用于第一输出端(A1)、第二输出端(A2)或第二输入端(E2)的端子中的至少一个之间的电流路径中,第一转换器(K1),所述第一转换器设置在高压分配器(6)和第三输出端(A3)之间并且将由高压分配器(6)提供的直流电压转换为较低的直流电压。本发明的另一方面是具有这种电流分配器单元的车辆。
