Abstract
The disclosure relates to a method for charging an intermediate circuit capacitor in an electric drive unit comprising an electric motor. The intermediate circuit capacitor is charged by an intermediate circuit current that is supplied by a battery. The output voltage of the battery is settable to one or more voltage values. A target value of the intermediate circuit current is determined, and an actual value of the intermediate circuit current is ascertained. The actual value of the intermediate circuit current is then compared with the target value of the intermediate circuit current. An optimal output voltage of the battery is determined on the basis of the comparison of the actual value of the intermediate circuit current with the target value of the intermediate circuit current. Then, the optimal output voltage of the battery is set.
