METHOD FOR CHARGING AN INTERMEDIATE CIRCUIT CAPACITOR

摘要

The invention relates to a method for charging an intermediate circuit capacitor (11) in an electric drive unit comprising an electric motor (13), wherein the intermediate circuit capacitor (11) is charged by an intermediate circuit current that is supplied by a battery (10), the output voltage of which can be set to one or more voltage values. First, a target value of the intermediate circuit current (101) is determined, and an actual value of the intermediate circuit current (102) is ascertained. The actual value of the intermediate circuit current is then compared with the target value of the intermediate circuit current (103). An optimal output voltage of the battery (104) 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. Finally, the optimal output voltage of the battery (105) is set.
