Abstract:

Both electric power systems and the transportation sector are essential constituents to modern life, enhancing social welfare, enabling economic prosperity and ultimately providing well-being to the people. However, to mitigate adverse climatological effects of emitting greenhouse gases, a rigorous de-carbonization of both industries has been set on the political agenda in many parts of the world. To this end, electrifying personal vehicles is believed to contribute to an affordable and reliable energy model that provides tolerable environmental impact.

Abstract:

Platooning concept involves a group of vehicles acting as a single unit through coordination of movements. While Platooning as an evolving trend in mobility and transportation diminishes the individual and manual driving concerns, it creates new risks. New technologies and passenger’s safety and security further complicate matters and make platooning attractive target for the malicious minds. To improve the security of the vehicular platooning, threats and their potential impacts on vehicular platooning should be identified to protect the system against security risks.

Measurements of orthogonally polarized MIMO channels were conducted in downtown Ottawa with dual-polarized receive array elements positioned along the sides of a measurement vehicle. The measured channel data are used to analyze characteristics of the polarized channel including the angular distribution of received power, diversity, correlation and cross-polarization discrimination. It is shown that if spatially separated antennas are replaced with dual-polarized elements the cross-polarization discrimination results in a performance loss that is partially compensated for by improved cross-pol

Abstract:

One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. It would therefore be advantageous to create a driveline with the main energy storage separated from a smaller energy buffer, designed to have high power capabilities and to withstand frequent and deep discharge cycles. It has been found that rotating kinetic energy storage in flywheels

A data-driven understanding of how a vehicle is used can help transportation companies improve their products and provide better service to their customers.

However, in order to improve and provide new services to customers it is often necessary to understand the operation of the vehicle in new ways with collection of new data that the vehicle sensors do not capture today. We hypothesize that a camera alone would be able to capture a large number of operational variables, thereby eliminating the need of multiple, costly se

Abstract:

Les objectifs de ce travail consistent à diminuer la consommation énergétique d'un véhicule électrique. Après avoir modélisé la chaîne de traction incluant un moteur asynchrone, un onduleur triphasé et sa commande ainsi que la mécanique, deux voies d'optimisation sont abordais. La première consiste à optimiser la commande en amont de l'onduleur. Différentes familles de commandes sont alors développées. La première commande optimise un critère sur une durée instantanée. Elle a été simulée, puis implantée sur véhicule. Elle apporte un gain d'autonomie significatif (quelques pourcents) et diminue

Abstract:

L'objectif de cette thèse est l'évaluation du vieillissement calendaire des supercondensateurs. Le début est consacré à l'examen des principes et des technologies des générations récentes de supercondensateurs. Ensuite, une modélisation comportementale de ces composants est proposée sur la base des principes physico-chimiques mais surtout à partir de méthodes de caractérisation électriques originales menées sur une plate-forme dédiée. La majeure partie des résultats concerne la quantification du vieillissement calendaire de différents types d'échantillons en focalisant sur l'impact de la tensi

Abstract:

Les travaux de cette thèse concernent les chargeurs à couplage inductif développés pour les flottes de véhicule électriques en libre service tel qu'envisagé dans l'opération PRAXITELE de EDF. L'objectif général était la définition de l'ensemble convertisseur-coupleur magnétique adapté à ce type de recharge. Les outils et les méthodes développés dans ce mémoire ont fait progresser la compréhension du couplage par induction, et éclairé le choix de la structure adaptée. L'étude méthodique des différentes structures à trois et à quatre éléments de stockage a fait ressortir quelques montages dignes

Abstract:

Ce travail se place dans le contexte de l'utilisation de machines à aimants permanents dans les véhicules hybrides ou électriques. Un modèle analytique, qui prend en compte les effets de la non linéarité du circuit magnétique, permet d'obtenir les pertes (Joule et fer) quel que soit le point de fonctionnement de la machine. Des cartes d'isorendement dans le plan couple-vitesse peuvent être tracées. Ce modèle a ensuite été utilisé pour étudier. Des variantes d'une machine synchrone à aimants. Des comparaisons de consommation sur cycles de route ont été effectuées sur ces machines, ainsi que l'é

Abstract:

L'objectif de cette etude est de developper une serie de modeles permettant de determiner le comportement electrochimique et thermique des accumulateurs au lithium a electrolyte solide polymere. Les phenomenes electrochimiques sont dans un premier temps abordes de facon macroscopiques (valeurs moyennes), puis les modeles sont ensuite affines grace en particulier a l'utilisation de produits de convolution pour representer le transport des especes. Cette approche va nous permettre d'une part de developper un modele tres souple et modulaire et d'autre part d'etudier des profils de decharge comple

Abstract:

Dans de proches années, les véhicules électriques (VEs) vont faire leur apparition massive sur les marchés. Cela peut avoir un impact important sur le fonctionnement des réseaux d’électricité actuels qui devront ajuster leur fonctionnement à la nouvelle demande massive d'électricité provenant des VEs. Par contre, les VEs peuvent aussi être vus comme une nouvelle opportunité dans le futur marché d’électricité. En effet, une décharge/recharge intelligente peut permettre aux VEs d’être un support de stockage d’électricité important, valable, et permanent dont la capacité croit en fonction du no

Abstract:

Cette thèse est consacrée au développement de techniques de commande avancées pour des classes de systèmes non linéaires en général et pour des applications automobiles en particulier.Pour répondre au besoin du contrôle moteur, la première partie propose des nouveaux résultats théoriques sur la technique de commande non linéaire à base de modèles de type Takagi-Sugeno soumis à la saturation de la commande. La saturation de la commande est traitée en utilisant sa représentation polytopique ou une stratégie anti-windup.La deuxième partie porte sur la commande du système d'air d'un moteur turboco
