Abstract

An apparatus and a method for determining an operating point-dependent change in resistance factor (AFAP) of an energy storage device, wherein a start resistance is determined at an operating point start point in time, wherein a change in resistance between a present resistance of the energy storage device and the start resistance is determined at least at an operating point end point in time, wherein an end resistance is determined as a sum of the start resistance and the change in resistance determined at the operating point end point in time, wherein the operating point-dependent change in resistance factor (AFAP) is determined as a ratio between the end resistance and a nominal resistance proportion of the start resistance, and to methods for determining an operating point-dependent resistance.
