Abstract

A vehicle-side charging circuit for a vehicle with electric drive. The charging circuit comprises an AC connector, a controlled rectifier which is connected to the AC connector, an electric machine with at least one winding, a current converter which is connected to the electric machine, and an energy-storage-device connector. The at least one winding of the electric machine is coupled in series between the rectifier and the current converter. In an inverter mode the current converter is fed from the energy-storage device, and in a charging mode the current converter is from an external energy source via at least one series-connected winding of the electric machine and charges the electrical energy-storage device.
