Abstract

A method for determining an information on an equivalent series resistance is disclosed and comprises: generating at least one excitation voltage signal and applying the excitation voltage to at least two measurement electrodes; measuring a response signal; determining a signal flank from the response signal and determining an ohmic signal portion from one or both of shape and height of the signal flank; and determining the information on the equivalent series resistance from the ohmic signal portion.
