Abstract (en)
[origin: WO2010084072A1] The invention relates to a method for determining an aging condition of a battery cell, comprising the steps of a) providing a battery cell; b) recording an impedance spectrum of the battery cell; c) determining an evaluation quantity based on the measured impedance spectrum; d) determining an aging condition of the battery cell based on a comparison of the evaluation quantity to a reference value.
