Hardware-in-loop simulation olatform for energy systems in hybrid electric vehicles

Hardware-in-loop (HIL) is an interesting methodology for developing and testing the operation of components in a complex system. In this paper, HIL is applied to a hybrid fuel cell/battery system that can be usually found in electric vehicles or peak-loaded stationary applications. The fuel cell is modeled dynamically in Matlab/Simulink by means of current interrupt tests. The system includes a dynamic simulation model of the fuel cell, whose parameters have been measured experimentally. The experimental results show the behavior of the different parameters of a real battery hybrid vehicle under a certain driving cycle.
