Abstract


The power management especially the power distribution strategy of the multi-sources energy system is an important issue. This paper presents a comparative study of power distribution strategies for the fuel cell and supercapacitor hybrid power source system. Two types of power distribution strategies have been put forward and compared systematically. The experiment and simulation results indicate that the fuel economy of different power distribution strategies depends on their driving schedule. However, the presented rule-based power distribution strategy has the potential to reduce energy shocks of the fuel cells and can prolong the lifespan of the fuel cells, which is more suitable for the fuel cell and supercapacitor hybrid power source system.
