Abstract
A motor vehicle includes an electric machine that can be connected or is connected to a rechargeable energy storage device for supplying electric energy by way of an intermediate power inverter. The energy storage device can be connected via a motor-vehicle-side charge connection element to an external energy supply device which makes available electric energy. The charge connection element has at least one device for generating a three-phase current from a single-phase or two-phase alternating current, wherein the device includes a circuit arrangement with at least one capacitor that is connected in parallel with at least one three-phase current winding.
