Abstract
A method for determining an electrical capacitance in an intermediate circuit of an electric drive system. The electric drive system includes at least one first electrical energy source, which feeds the intermediate circuit, a drive unit, which has an inverter and an electrical load, the inverter being electrically connected on the input side with the intermediate circuit and on the output side with the electrical load, and a DC voltage converter, which is electrically connected with the intermediate circuit and measures a voltage in the intermediate circuit by high frequency sampling. The electrical capacitance in the intermediate circuit is determined from the voltage in the intermediate circuit measured by the DC voltage converter. Also described is a motor vehicle, which includes an electric drive system for implementing the method.
