This study investigates the use of the electrochemical impedance spectroscopy (EIS) technique as an alternative to the DC pulses technique for estimating the power capability decrease of lithium‐ion batteries during calendar ageing. On the basis of results obtained from calendar ageing tests performed at different conditions during 1–2 years, a generalised model that estimates the battery power capability decrease as function of the resistance Rs increase (obtained from EIS) was proposed and successfully verified.
