Abstract (en)
[origin: WO2023006729A1] The invention relates to an electrical drive system (1) for a vehicle, comprising - an electrical three-phase machine (2) for driving the vehicle, - an electrical energy store (3) for electrically supplying the electrical three-phase machine (2) during a driving operation of the vehicle, - an inverter (4) of the electrical three-phase machine (2), which inverter is electrically coupled to the electrical energy store (3), and - a charging connection (5) on the vehicle side for electrically coupling the electrical energy store (3) with a vehicle-external charging unit (6), wherein - a charge voltage (UL) of the charging connection (5) on the vehicle side can be transformed into a supply voltage for charging the electrical energy store (3) as a function of the inverter (4). The invention further relates to a method.
