摘要
分析了功率混合型燃料电池汽车动力系统的特征,给出了功率混合型动力系统能量分配算法的实用设计原则,阐述了该型动力系统适用的恒压能量分配方式,并依据提出的设计原则进行了能量分配算法设计。在燃料电池城市客车“清能3号”的应用中,又提出一种分模式控制解决方案。实验证明,所设计的算法能综合考虑动力系统的部件安全性、动力性和经济性,具有一定的应用价值。
The features of power system of power-type fuel cell vehicle are analyzed with the design guidelines for its energy distribution algorithm given. The constant-voltage type energy distribution algorithm is exposited and specifically designed. In its application to fuel cell city bus＂ Qingneng 3 ＂, a dual-mode control scheme with switching logic is further proposed with an experiment conducted. The results show that the algorithm can concurrently take account of safety, performance and fuel economy and is valuable for practical use.
