Claim:
1. A charging device for an electric energy storage device of a motor vehicle, comprising: a DC-DC converter coupled to the electric energy storage device, wherein output power of the DC-DC converter provides charging power for the electric energy storage device; a first interface configured to be hard-wired to a first external AC network for charging the electric energy storage device; a second interface configured for inductive coupling with a second external AC network for charging the electric energy storage device; and a third interface configured to be hard-wired to an external direct voltage source for charging the electric energy storage device, wherein an input of the DC-DC converter is configured to be supplied with electric power over the third interface simultaneously with at least one of the first interface and the second interface, and wherein the DC-DC converter is configured to simultaneously receive a maximum power output from the third interface and a maximum power output from the at least one of the first interface and second interface, where the maximum power output from the third interface is different than the maximum power output from the at least one of the first interface and second interface.
