The present invention relates to a method for investigating an ageing condition of a battery (10) which is provided for power supply to an electric motor (20), comprising the steps of: determining at least one graphical progression of at least one operating parameter of the battery (10), checking the at least one graphical progression on at least one sinusoidal curve portion, if at least one sinusoidal curve portion is recognised, extracting the at least one sinusoidal curve portion, calculating an impedance of the battery (10) by means of impedance spectroscopy with reference to the at least one sinusoidal curve portion, and determining the ageing condition of the battery (10) with reference to the calculated impedance. The invention further relates to a computer program (30), a memory means, a control device (40) and a vehicle (100).
