Electric drive system of a motor vehicle and method for controlling the temperature of drive system components of such an electric drive system

An electric drive system of a motor vehicle comprising:

• at least one electric energy storage system;
• at least one power electronics;
• and
• at least one electrical machine to drive at least one drive wheel of the motor vehicle,
• wherein the at least one electrical energy storage system, the at least one power electronics and the at least one electrical machine each constitute a drive system component of the electric drive system and are functionally coupled with each other,
• wherein at least two of the drive system components are part of an optimization module, which is configured to perform a performance-optimized relative temperature control of the at least two drive system components,
• wherein the optimization module has at least two temperature detection units and at least one switching device coupled to a temperature control device in order to operate the at least one switching device as needed depending on actual temperature values recorded by the at least two temperature detection units, and
• wherein, in the performance-optimized relative temperature control of the optimization module, a current performance of the at least two drive system components is determined in dependence on a current component temperature, a currently deliverable power of the at least two drive system components is compared in order to determine which of the at least two drive system components delivers the lowest power, and a temperature of the drive system component that delivers the lowest power is controlled.
