This thesis compares energy management strategies implemented for a hybrid electric vehicle powered by a fuel cell and an energy-storage system. The main goal of these strategies is to control the power flow between the two energy sources in order to minimize the hydrogen consumption of the fuel cell during a driving cycle, while fulfilling the constraints of fuel cell power and state of charge of the energy-storage system. Also, the state of charge at the end of the driving cycle needs to be the same as the one at the beginning.
Using SimDriveline and SimPowerSystems toolboxes of Matlab/Simulink, a simulation model for the fuel cell hybrid vehicle has been built. Rule-based and optimization-based strategies have been implemented. They are the followings: The thermostat strategy, the proportional integral strategy, the maximal efficiency strategy, the global optimization based on hybridization of stochastic and deterministic methods, and the equivalent consumption minimization strategy.
The strategies are tested with three driving cycles of short and long duration.
