The invention relates to a vehicle (1) having a power circuit arrangement (2), the power circuit arrangement (2) having a traction battery (4), an electrical terminal (5) for electrical connection to an external power unit (3), a first high-voltage potential (P1) and a second high-voltage potential (P2), the first high-voltage potential (P1) being a positive high-voltage potential and the second high-voltage potential (P2) being a negative high-voltage potential, or vice versa. In this case, the circuit arrangement (2) has two electric drive units (A1, A2), each having an inverter (I1, I2) and a three-phase electric motor (M1, M2) electrically connected thereto, for driving the vehicle (1), and the circuit arrangement is designed such that the two electric drive units (A1, A2) are electrically connected to the inverter (I1, I2). The electrical drive unit (A1, A2) can be electrically connected in series between the electrical connection (5) and the traction battery (4) in such a way that, from the electrical connection (5) towards the traction battery (4), the first electrical drive unit (A1) increases a first high-voltage potential (P1) and the second electrical drive unit (A2) increases a second high-voltage potential (P2). According to the invention, the inverters (I1, I2) each have a respective capacitor (C1, C2) between the potential line (PL1) of the first high-voltage potential (P1) and the potential line (PL2) of the second high-voltage potential (P2), the circuit arrangement (2) being designed such that the second electric drive unit (A2) can be electrically connected in series to the capacitor terminals of the first electric drive unit (A1).
本发明涉及一种具有电力电路装置(2)的车辆(1),其中,电力电路装置(2)具有:牵引电池(4)、用于电连接至车外电力单元(3)的电接线端(5)、第一高压电位(P1)和第二高压电位(P2),其中,第一高压电位(P1)是正高压电位且第二高压电位(P2)是负高压电位,或者反之。在此情况下,所述电路装置(2)具有两个电驱动单元(A1,A2),所述电驱动单元分别具有一个逆变器(I1,I2)和一个与之电连接的三相交流电机(M1,M2),用于驱动车辆(1),并且所述电路装置被如此设计,即,这两个电驱动单元(A1,A2)能够按下述方式电串联在电接线端(5)与牵引电池(4)之间,即,从电接线端(5)朝着牵引电池(4),第一电驱动单元(A1)提高第一高压电位(P1)并且第二电驱动单元(A2)提高第二高压电位(P2)。本发明规定,逆变器(I1,I2)在第一高压电位(P1)的电位线(PL1)与第二高压电位(P2)的电位线(PL2)之间分别具有相应的电容器(C1,C2),其中,如此设计电路装置(2),即,第二电驱动单元(A2)能够被电串联至第一电驱动单元(A1)的电容器接线端。
