Véhicules hybrides à pile à combustible :
dimensionnement et stratégies de commande.

Abstract : A fuel cell consumes hydrogen and oxygen to produce clean electric energy. The only byproducts are water and heat. Therefore fuel cell vehicles are considered for the long term sustainable mobility. In a fuel cell hybrid vehicle (FCHV), the electric powertrain is powered by a fuel cell system (FCS) and an energy storage system (ESS). This energy storage system can be either batteries or supercapacitors. The hybrid architecture allows defining power management strategies and offers opportunities in the powertrain sizing. Global optimisation algorithms provide a power split between the FCS and the ESS which minimizes the hydrogen consumption for a priori known driving cycles. The optimal results obtained cannot be used in real time application but they define benchmarks for control strategies evaluation. In this thesis, a sub-optimal real time strategy is proposed based on the optimal control algorithm. The hydrogen consumption also relies on the powertrain sizing. The FCS and ESS sizes should respect the vehicle dynamic capabilities (speed, acceleration) without penalizing the energetic aspects. A sizing tool which helps in the powertrain design is proposed. Finally in this thesis, the theoretical approaches concerning control strategies and sizing procedures are illustrated and validated by real applications (PAC-Car II prototype, Hy-Muve prototype, test bench).
