The invention relates to an electric drive system (1) for a vehicle, comprising: a first three-phase AC motor (5) and a second three-phase AC motor (6) for driving at least one drive shaft (4) of the vehicle; an accumulator (2) for supplying the first and the second three-phase AC motor (5, 6) during a driving operation of the vehicle, a first inverter (9) of the first three-phase AC motor (5) and a second inverter (10) of the second three-phase AC motor (6) being connected to the accumulator (2), respectively; and a vehicle-side charging connection (3) for electrically connecting the energy storage device (2) to a charging unit (11) outside the vehicle, a charging voltage (UL) of the vehicle-side charging connection (3) being convertible into a supply voltage (UV) for charging the energy storage device (2) by means of the first and/or second inverter (9, 10). The invention also relates to a method.

    本发明涉及一种用于车辆的电驱动系统(1),具有:用于驱动该车辆的至少一个驱动轴(4)的第一三相交流电机(5)和第二三相交流电机(6);用于在车辆的行驶操作期间给第一和第二三相交流电机(5,6)供电的蓄电器(2),其中,第一三相交流电机(5)的第一逆变器(9)和第二三相交流电机(6)的第二逆变器(10)分别连接至蓄电器(2);以及用于将蓄电器(2)电连接至车外充电单元(11)的车侧充电接线口(3),其中,凭借第一和/或第二逆变器(9,10)可将车侧充电接线口(3)的充电电压(UL)变换为用于给蓄电器(2)充电的供电电压(UV)。本发明还涉及一种方法。
