Comparaison entre quatre solutions pour échanger de l'énergie entre systèmes de forte capacité de stockage

International audienceL'électrification de systèmes toujours plus puissants est habituellement corrélée à de plus grands besoins de fiabilité, continuité de service et échanges d'énergie entre sources. Dans le domaine des systèmes de stockage électrochimique d'énergie, ces besoins sont souvent satisfaits en parallélisant des batteries. La déconnexion de deux batteries en parallèle est un processus simple et bien maîtrisé. En revanche, la connexion est un processus bien plus long et compliqué qui requière de l'électronique de puissance adaptée car cela revient à connecter en parallèle deux sources de tension. Basé sur un cas concret d'application et grâce à des simulations, cet article propose une comparaison entre quatre solutions pour échanger de l'énergie entre systèmes batterie lithium-ion et maitriser la connexion en parallèle de ceux-ci

Comparison between energy battery and power one for electrical vehicle applications

ISBN 978-3-8007-3229-6International audienceIn 2009, a presentation was done in PCIM about the experience feedback on electric vehicles of the French car fleet and about the replacement of the initial NiCd battery of an AX vehicle by an iron phosphate Lithium battery with 1600 small cells. Theses cells are power ones. This presentation is a comparison between this power battery and an energy battery in the same format

Comparaison entre batterie d'énergie et batterie de puissance pour l'application véhicule électrique

International audienceEn 2008, une présentation sur le retour d'expérience des véhicules électriques produits en France depuis les années 1995 avait montré le niveau très faible de la fiabilité des batteries, qui amenait à un coût d'usage prohibitif, trois fois plus élevé qu'un véhicule thermique. Depuis, les batteries d'origine ont été remplacées par des batteries au lithium à base de phosphate de fer qui présentent des hauts niveaux de sécurité. Cette nouvelle batterie est une batterie de puissance. Cette présentation est une comparaison entre les performances de cette batterie de puissance et une batterie d'énergie ayant le même format. La capacité spécifiée de la batterie d'énergie est 39 % plus élevée que la batterie de puissance. Cependant, pour une décharge en moins d'une heure, telle que nécessaire sur véhicule, l'énergie délivrée est bien plus faible à cause de la résistance interne et de pertes additionnelles visibles sur le cycle d'hystérésis de charge décharge. A température ambiante, le gain réel est faible. A basse température, la batterie de puissance est la plus performante

Comparison of power electronics solutions to exchange energy between high voltage batteries

International audienceElectrification of always more powerful systems is usually correlated to higher needs in reliability, service continuity and energy exchanges between sources. In the field of energy storage systems, these needs are often addressed by parallelization of batteries, which are automatically disconnected in case of fault. The service continuity is thus simply ensured. If the disconnection of two batteries in parallel is an instantaneous process well controlled, the connection is a longer process more complicated, which requires adapted power electronics solutions. Based on a concrete case of application and thanks to simulations, we propose in this paper to compare different solutions to exchange energy between two lithium ion battery systems. This question has been addressed in the framework of a H2020 European project named ESPRIT "Easily Distributed Personal Rapid Transit". In the first part of the paper we will present the project and more precisely the societal benefits, the main objectives and the first important results. The second part of the paper will deal with the comparison of power electronics solutions designed to exchange energy between batteries

ESPRIT project: an innovative electric car sharing solution

International audienceESPRIT project is an important research project financed by Europe for 8.9 M€ in the framework of the program H2020 and coordinated by CEA (Commissariat à l'énergie atomique et aux énergies alternatives). The goal of ESPRIT project is to decrease the usage of individual cars in urban area and to complete the usage of public transport. It is ESPRIT deals with the development of some small electric cars which can be mechanically coupled to create road trains. This vehicles can be used within a carsharing system in city center and peri-urban area. These vehicles will allow for user to complete a trip done with public transport and perform the first or the last kilometer with a non-pollutant system. The aptitude to be coupled in road train allows the redistribution to secure the availability of vehicles in stations. That permits to propose a high reliability system with a limited investment cost. This paper shows the work done during the 3 years of the project. In 2016 a first paper [6] about this project was presented in PCIM: "Comparison between standard and innovative solutions to exchange energy between high energy storage systems". This first paper was dedicated to a subsystem inside the vehicle. In this second paper we are more focusing on the final results of the project
