Model-based energy management strategy for hybrid electric vehicle

In FC/UC HEV, an adequate power management approach is one essential objective of the researches in this area. In this paper, an advanced control strategy managing the power distribution among the two energy sources is elaborated using state-flow bloc of Matlab/Simulink. For the FC power demand, an algorithm with filtering power vibrations is developed. This algorithm, depending on the UC state of charge (SOC) and the vehicle speed to minimize the FC power demand transitions and enhance its life time.
