The aim of this thesis is the evaluation of calendar aging of supercapacitors. The beginning is devoted to an examination of the principles and technologies of the latest generation of supercapacitors. Then, behavioral modeling of these components is proposed on the basis of physico-chemical principles but also from original electrical characterization methods conducted on a dedicated platform. The main part of the results concerns calendar aging quantification of various types of supercapacitors by focusing on the effect of voltage and temperature. Finally, these results, taken into account in the models, are compared to those obtained during power cycling. So, individual contributions are identified.
