Contrôle des circuits d’équilibrage des systèmes de stockage d’énergie (supercondensateurs) en vue d’estimer et d’améliorer leur durée de vie

Abstract : Energy storage system such as supercapacitors are widely used in high power applications. However, due to single cell voltage limitation, an energy storage system (module) is often employed. It contains a chain structure of identical elements and ensures voltage adaptation to the corresponding application requirements. Energy management systems are associated to energy storage systems in order to assure user and equipment security. Their main role is to monitor and control energy storage systems elements continuously. The work presented aims to enhance the lifetime of energy storage systems. It relies on establishing balancing circuits on the terminals of the storage system elements. These control circuits are energy management system devices. Thus, various control approaches are discussed, analyzed and compared. They aim to estimate the supercapacitor's state of health. In addition, a new approach of balancing circuits is proposed. It is based on estimating the level of degradation of the elements. Thus, It allows aging speed equalization between module elements and storage system lifetime maximization. Some main results of the work could be generalized to batteries
