An electric drive system for a vehicle includes first and second three-phase electric machines driving a vehicle axle and an electrical energy store electrically supplying the first and second three-phase electric machines during a driving operation of the vehicle. A first and second inverter of the first and second three-phase electric machines, respectively, are each coupled to the electrical energy store. The system also includes an onboard charging terminal for electrically coupling the electrical energy store to a charging unit external to the vehicle. According to the first and/or second inverter, a charging voltage of the onboard charging terminal is converted into a supply voltage for charging the electrical energy store.
