Contribution à l’étude du vieillissement des composants batterie et pile à combustible en usage réel

Abstract : These thesis works are associated to the AsDeCoEUR project. This project is part of the current context of the development of new energy technologies for mobility and focuses more specifically on the study of battery and fuel cell components located in the heart of electric power train. The project is based on the work already carried out by the UTBM and IFSTTAR actors of the FCLAB research federation among the Mobypost project. Mobypost european project has allowed the experimentation of a fleet of 10 fuel cell electric vehicles under actual operating conditions on two postal platforms in the Franche-Comté region.During the Mobypost experiment, a deep monorting was performed on all the vehicles so numerous physical data of their power train were recorded. All of these information now constitutes a very rich database to exploit. Among the AsDeCoEUR project, we propose a scientific approach carried out around a thesis work wich aims at understanding dynamic behavior, studying aging and estimating the state of health of batteries and fuel cells in real use. This approach is based on the analysis of the data recorded on these components among the Mobypost project and is reinforced by specific experiments set up in the laboratory. The implementation of skills and digital analysis tools developed especially for batteries by the Ampère laboratory and IFSTTAR aims at understanding and reproducing the degradation phenomena. The works should finally allow, by combining the skills of UFC, UTBM, IFSTTAR and Ampère laboratory researchers, to contribute to the study of batteries and fuel cells aging and to estimate their state of health under actual operating conditions. This constitutes a remarkable advance in this field, particularly with a view to the industrialization of vehicles equipped with this type of component.
