Abstract (en)

[origin: WO2017055428A1] The invention relates to a method for determining a real component of a complex internal resistance of a battery, wherein associated battery voltage values and battery current values are measured at a plurality of measuring time points, said values being produced corresponding to a number of connected consumers, and wherein a frequency-independent real component is determined using a calculation rule based on said battery voltage values and battery current values.
