A method is provided for operating an electric drive system () with an electric machine () that comprises a first multiphase winding operatively coupled to a first inverter (), and has at least one second multiphase winding that is coupled to a second inverter (), A first energy storage () is arranged upstream of the first inverter (), and a second energy storage () is arranged upstream of the second inverter (). The method includes: operating the electric machine () by providing a first power flow between the first energy storage () and the first multiphase winding; and energizing the second inverter () so that a second power flow can be provided between the first energy storage () and the second multiphase winding. An electric drive system also is provided for carrying out the method.
