A loading state determiner for determining a loading state of an electric power source including a source impedance includes a voltage drop determination circuit which is implemented to provide, based on a detection of an instantaneous current provided under load by the power source to a load, an electric quantity describing a voltage drop at a source impedance of the power source. Further, the loading state determiner includes an evaluation circuit which is implemented to obtain, based on electric quantity describing the voltage drop at the source impedance of the power source and an electric quantity describing a terminal voltage of the power source, a load state signal carrying information on an instantaneous relation between the terminal voltage of the power source and a no-load voltage of the power source.
