Caractérisation Multi-physique des éléments de stockage électrochimique et électrostatique dédiés aux systèmes Multi sources : Approche systémique pour la gestion dynamique d'énergie électrique

Abstract : This thesis work is a continuation of the research activities of the GREAH laboratory on the issues of the management of electrical energy and improving the energy quality of production systems for renewable energy. Indeed, the coupling of several different nature sources entails the problems of dimension, quality of energy and the lifetime of the interconnected elements. The scientific approach is based on the characterization of the evolution of the resistances and capacitances of the batteries/supercapacitors cells according to the electrical and thermal constraints, followed by the modeling of accelerated cells aging. In this thesis, we propose improvements to the dynamic response of an electric propulsion fluvial boat by using the hybrid system of lithium-batteries and supercapacitors. We also propose an electrothermal approach for the multi-physical characterization and modeling of the batteries and supercapacitors aging, using combined constraints of the temperature and frequency of the DC current ripples. The experimental data has been collected to establish models of batteries and supercapacitors dedicated to multi-source systems including renewable energy sources (wind and tidal turbines). The results of the developed models shown high accuracy compared with experimental results. These models illustrated a good description of the aging phenomenon of batteries/ supercapacitors due to charging/discharging operations with a fluctuating continuous current combined with a variable temperature.
