Abstract (en)
[origin: WO2023006749A1] The invention relates to an electric drive system (1) for a vehicle, comprising: - a first three-phase electric machine (5) and a second three-phase electric machine (6) for driving at least one drive axle (4) of the vehicle; - an electrical energy store (2) for electrically supplying the first and second three-phase electric machines (5, 6) during driving operation of the vehicle, to which electrical energy store (2) a first inverter (9) of the first three-phase electric machine (5) and a second inverter (10) of the second three-phase electric machine (6) are each coupled; and - an onboard charging terminal (3) for electrically coupling the electrical energy store (2) to a charging unit (11) external to the vehicle; wherein, in accordance with the first and/or second inverter (9, 10), a charging voltage (UL) of the onboard charging terminal (3) can be converted into a supply voltage (UV) for charging the electrical energy store (2). The invention also relates to a method.
