Therefore fuel cell systems are always combined with other energy storage devices like batteries and supercapacitors to increase the power density of the power system and fulfill the load power demands.

In addition, the power fluctuations will damage the fuel cell stacks and shorten the cycle life of fuel cells. The sole fuel cell system cannot satisfy the dramatical change of motor power demands. In recent years, fuel cell vehicles have attracted attention for their zero emission and environmental friendship. This approach can be applied for solving complex problems in other engineering applications.

It is concluded that this method is a feasible and powerful method for evaluating the battery equalization circuit. It is found that the proposed method simplifies the complex equalization circuits into graphs and facilitates the comparison of the average efficiency of the system. It is observed that the proposed multiphase interleaved converter has flexible characteristics, while it has low energy loss compared with the conventional methods. The proposed method is verified by constructing a lithium-ion battery pack with the equalization circuit. The parameter of average efficiency is considered as an important indicator to evaluate the characteristics of the equilibrium system. It is intended to establish a unified standard for the comparison. Moreover, the graph theory is applied to the analysis of equalization circuits.

The present study proposes a flexible multiphase interleaved converter for the energy equalization of a lithium battery pack with series configuration. The motivation of the present study is to serve the growing needs of the energy balance for lithium-ion battery packs. However, the power inconsistency of the battery packs restricts the developments of modern technologies in energy storage area. Lithium-ion batteries play an important role in large-scale energy storage systems.
