In this paper, the ageing monitoring of lithium-ion cell during power cycling tests is investigated. First of all, the results of a time-domain characterization method have been used to identify the main factors of ageing. Then, a methodology that takes benefits of a periodic characterization protocol based on impedance spectroscopy measurements is proposed. The obtained results are presented and discussed for different values of State-of-Charge (SoC), temperature and number of cycles. In a second part of this study, we have focused on how to take into account the ageing in a simulation model. This model is based on an equivalent electric circuit. The main ageing mechanisms and the influencing factors are highlighted and described using time-domain and frequency-domain measurements. Then, by focusing on the parameters evolution of the proposed model with ageing, it was confirmed that the growth of the solid electrolyte interface is the most influent phenomenon in the performances fading.
