A fuel cell hybrid vehicle (FCHV) which combines a fuel cell system (FCS) and a battery is the target system in this research. The fuel economy of the FCHV depends on its power management strategy, which determines the power split between the FCS and the battery. In this paper, the equivalent consumption minimization strategy (ECMS) for FCHVs is compared to the optimal control strategy based on Pontryagin's Minimum Principle (PMP) and Dynamic Programming (DP) for FCHVs. The ECMS is originally based on the heuristic concept that the usage of the electric energy can be exchanged to equivalent fuel consumption. Both the PMP and DP are based on the optimal control theory, they minimize the fuel consumption and optimize the power distribution between the FCS and the battery. The PMP gives the optimal solution by providing the necessary optimality conditions, and the DP provides the global optimal solution. The ECMS is based on the heuristic concept, though it is also related to the optimal concept because the solution of the ECMS is obtained by minimizing the total equivalent fuel consumption. To verify the relationship between the ECMS and the optimal control strategy, the solution obtained from the ECMS is compared to the solutions derived from the PMP-based optimal control strategy and the DP.
