A motor vehicle has an electric system that includes an inverter with load contacts for connecting a load at a first voltage, first and second battery contacts, and charging contacts for connecting a charging station that provides a higher second voltage. A switching matrix of the inverter includes inverter power switches and two additional switches directly connected to different ones of the inverter power switches. In a first switching state, the additional switches set the inverter to a driving mode for driving the load at the first voltage. In a second switching state, the additional switches set the inverter to a charging mode for charging the battery at the higher second voltage. For this purpose, the additional switches connect the first and second battery contacts in parallel in the driving mode and in series in the charging mode.
