Abstract
A method for operating an electric drive system of a vehicle where the electric drive system has an electric three-phase motor, a battery, and an inverter via which the electric three-phase motor is couplable electrically to the battery. A neutral point of the electric three-phase motor is couplable electrically to a positive pole connection of a direct current charger connection of the electric drive system. A negative potential line of the battery is couplable electrically to a negative pole connection of the direct current charger connection of the electric drive system. The neutral point is couplable electrically via a first switch to the positive pole connection. The negative potential line is couplable electrically via a second switch to the negative pole connection. The positive pole connection is couplable electrically via a third switch to a tap of an intermediate circuit capacitor.
