摘要： A method for determining an aggregate state of an operating liquid in an operating liquid container for a motor vehicle, which operating liquid container has at least one capacitor fastened to a container wall of the operating liquid container and has a first electrode and a second electrode opposite said first electrode. A first method determines the aggregate state of the operating liquid by means of a frequency-dependent phase profile of the impedance of the at least one capacitor. Another method determines the aggregate state of the operating liquid by means of a frequency-dependent capacitance profile of the at least one capacitor. Further, an operating liquid container is designed for carrying out the methods.
