Les v\u00e9hicules \u00e9lectriques et hybrides sont des \u00e9l\u00e9ments cl\u00e9s pour r\u00e9duire l’impact du domaine du\u00a0transport sur le r\u00e9chauffement climatique et sur l’\u00e9puisement des ressources fossiles. En raison des\u00a0limites des diff\u00e9rents syst\u00e8mes de stockage et de conversion d\u2019\u00e9nergie en termes de puissance et\u00a0d’\u00e9nergie, les hybridations sont int\u00e9ressantes pour les v\u00e9hicules \u00e9lectrifi\u00e9s. Ces sources d’\u00e9nergie\u00a0et ces conversions combin\u00e9es doivent \u00eatre g\u00e9r\u00e9es par des strat\u00e9gies de gestion de l’\u00e9nergie (SGE).\u00a0Parmi celles-ci, les m\u00e9thodes bas\u00e9es sur l’optimisation pr\u00e9sentent un int\u00e9r\u00eat en raison de leur\u00a0approche syst\u00e9matique et de leurs performances \u00e9lev\u00e9es. N\u00e9anmoins, ces m\u00e9thodes sont souvent\u00a0compliqu\u00e9es et demandent beaucoup de temps de calcul, ce qui peut \u00eatre difficile \u00e0 r\u00e9aliser dans\u00a0des applications r\u00e9elles. L’objectif de cette th\u00e8se est de d\u00e9velopper des SGE simples mais efficaces\u00a0bas\u00e9es sur l’optimisation en temps r\u00e9el pour une voiture \u00e9lectrique et un camion \u00e0 traction hybride\u00a0parall\u00e8le. Dans les deux cas, le syst\u00e8me de stockage de l’\u00e9nergie \u00e9lectrique est hybride (batterie et\u00a0supercondensateurs). La complexit\u00e9 des syst\u00e8mes \u00e9tudi\u00e9s est r\u00e9duite de fa\u00e7on syst\u00e9matique en\u00a0utilisant la repr\u00e9sentation macroscopique \u00e9nerg\u00e9tique (REM). La th\u00e9orie du contr\u00f4le optimal est\u00a0ensuite appliqu\u00e9e \u00e0 ces mod\u00e8les r\u00e9duits pour r\u00e9aliser des SGE originales, applicables en temps\u00a0r\u00e9el. Les r\u00e9sultats de la simulation montrent des gains int\u00e9ressants en termes de consommation de\u00a0carburant et de dur\u00e9e de vie de la batterie. La partie exp\u00e9rimentale d\u00e9montre le caract\u00e8re temps\u00a0r\u00e9el des strat\u00e9gies d\u00e9velopp\u00e9es par l’approche unifi\u00e9e de la th\u00e8se.<\/p>\n

Abstract<\/span><\/strong><\/p>\n

Electric and hybrid vehicles are key to reducing the impact of the transportation sector on global\u00a0warming and the depletion of fossil resources. Because of the limitations of different energy\u00a0storage and conversion systems in terms of power and energy, hybridizations are interesting for\u00a0electrified vehicles. These combined energy sources and conversions must be managed by Energy\u00a0Management Strategies (EMS). Among these, optimization-based methods are of interest because\u00a0of their systematic approach and high performance. Nevertheless, these methods are often\u00a0complicated and require a lot of computing time, which can be difficult for real-world applications.\u00a0The objective of this thesis is to develop simple but effective EMS based on real-time optimization\u00a0for an electric car and a parallel hybrid truck. In both cases, the storage system of electrical energy\u00a0is hybrid (battery and supercapacitors). The complexity of the studied systems is reduced in a\u00a0systematic way using the energetic macroscopic representation (EMR). The theory of optimal\u00a0\u00a0control is then applied to these reduced models to achieve original EMS which are applicable in\u00a0real-time. The simulation results show interesting gains in terms of fuel consumption and battery\u00a0life span. The experiments demonstrate the real-time ability of the strategies developed by the\u00a0unified approach of the thesis.<\/p>\n
