Abstract
A charging station for the inductive charging of a battery of a motor vehicle. A primary resonant circuit for generating an electrical oscillation, the primary resonant circuit has a primary capacitor and a primary coil. The charging station includes a measuring device designed to excite the primary resonant circuit up to a predefinable voltage amplitude, then to interrupt the excitation of the primary resonant circuit and to evaluate the time function of the voltage amplitude of the primary resonant circuit after the interruption of the excitation of the primary resonant circuit.
