Book Description
Ce mémoire présente une étude sur le diagnostic et le vieillissement des éléments de stockage de l'énergie électrique au bord du véhicule électrique/hybride. Il développe des modèles permettant le diagnostic en ligne de l'état de santé et de l'état de charge des supercondensateurs et des batteries Lithium-ion. Le banc de test développé dans notre laboratoire a permis d'élaborer une base de données importante sur le vieillissement des systèmes de stockage sous différentes conditions de stress. Des caractérisations ont été aussi réalisées à chaque étape de vieillissement et pour différentes contraintes. Ces travaux ont mis en œuvre un modèle de vieillissement calendaire des supercondensateurs. Contrairement à d'autres modèles de vieillissement, où la perte de capacité est supposée linéaire par rapport au temps de vieillissement, le modèle proposé tire profit de la réaction chimique mettant en évidence les paramètres provoquant le processus de vieillissement. En se basant sur la base des données expérimentale, une comparaison entre les résultats expérimentaux des différents modèles de vieillissement met en évidence la haute précision de l'estimation pour modèle de vieillissement calendaire proposé dans diverses conditions de fonctionnement. Ensuite, différents modèles sont proposés pour le diagnostic de l'état de santé et de l'état de charge des supercondensateurs et des batteries Lithium-ion. En effet, trois modèles de diagnostic de vieillissement des supercondensateurs en ligne sont présentés. Les stratégies proposées capitalisent les capacités d'estimation de trois observateurs connus pour leur performance dans l'estimation en ligne, à savoir : - Le filtre de Kalman étendu, - L'observateur à modes glissants, - L'observateur adaptatif. De l'autre côté, un modèle de diagnostic hybride pour l'estimation de l'état de charge et de l'état de santé des batteries Lithium-ion est présenté en considérant la variation de leur température de surface. La stratégie proposée se base sur les performances du filtre de Kalman étendu pour estimer l'état de charge, pendant que la technique d'estimation adaptative est utilisée pour une estimation robuste de l'état de santé.

Book Description
This book focuses on the methods of storage commonly used in hybrid systems. After an introductory chapter reviewing the basics of electrochemistry, Chapter 2 is given over to the storage of electricity in the form of hydrogen. Once hydrogen has been made, we have to be able to convert it back into electricity on demand. This can be done with another energy converter: a fuel cell, the subject of Chapter 3. Such a system is unable to deliver significant dynamics in terms of storage and release of electricity and needs to be supplemented with another solution: a detailed study of supercapacitors is provided in Chapter 4.While the storage systems touched upon in the previous three chapters (hydrogen batteries and supercapacitors) both exhibit advantageous characteristics, at present they are still relatively costly. Thus, the days of the electrochemical accumulator by no means appear to be numbered just yet. This will therefore be the topic of Chapter 5. Finally, on the basis of the elements laid down in the previous chapters, Chapter 6 will focus on electrical hybridization of these storage systems, with a view to enhancing the performance (in terms of energy, lifetime, cost, etc.) of the newly formed system. Aimed at an audience of researchers, industrialists, academics, teachers and students, many exercises, along with corrected solutions, are provided throughout the book. Contents 1. Basic Concepts of Electrochemistry used in Electrical Engineering. 2. Water Electrolyzers. 3. Fuel Cells. 4. Electrical Energy Storage by Supercapacitors. 5. Electrochemical Accumulators. 6. Hybrid Electrical System. About the Authors Marie-Cécile Péra is a Full Professor at the University of Franche-Comte in France and Deputy Director of the FEMTO-ST Institute (CNRS).

Book Description
Hydrogen is the most abundant element in the universe. It has a place in the energy mix of the future, especially regarding fuel cells (FCs). This book is an investigation into FCs. Prominence is given to the subject of PEMFCs (proton exchange membrane fuel cells) as they offer interesting perspectives on transport and stationary applications. This being said, a number of technological and scientific obstacles remain to be overcome before an industrial level of development can be reached.

Book Description
Trade can dramatically improve women’s lives, creating new jobs, enhancing consumer choices, and increasing women’s bargaining power in society. It can also lead to job losses and a concentration of work in low-skilled employment. Given the complexity and specificity of the relationship between trade and gender, it is essential to assess the potential impact of trade policy on both women and men and to develop appropriate, evidence-based policies to ensure that trade helps to enhance opportunities for all. Research on gender equality and trade has been constrained by limited data and a lack of understanding of the connections among the economic roles that women play as workers, consumers, and decision makers. Building on new analyses and new sex-disaggregated data, Women and Trade: The Role of Trade in Promoting Gender Equality aims to advance the understanding of the relationship between trade and gender equality and to identify a series of opportunities through which trade can improve the lives of women.
