Development of Hybrid Power Train for Fuel Cell City Bus in China

摘要

This paper presents current status in development of hybrid power train for fuel cell city bus, which is supported by China government. The hybrid power train is the key part of the fuel cell city bus, which can determine the performance of the fuel cell city bus in essential. The technologies of hybrid power train includes the choice of power train configuration, the matching of components and the optimization of control algorithms, which can promote the harmonious operation and excellent performance of components, such as fuel cell system, battery pack, motor & its controller, power electronics devices and so on. In this paper, the hybrid power train configuration is proposed, and the structures and schemes of fuel cell hybrid power train simulator and experiment platform are given. The studies on control algorithms, electrical integration and evaluation test, which are carried out on the experiment platform, are developed.
