混合动力客车复合电源结构设计与参数匹配优化研究

Optimizing Study on Structural Design with Synergic Electric Power Supply and Parameter Matching of Hybrid Electric Vehicle

搭载高效、经济和长寿命复合电源系统是城市混合动力客车发挥节能、环保优势的关键。文章在系统分析蓄电池、超级电容器和DC/DC转换器特性的基础上,在"削峰填谷"思想的指导下,设计了复合电源结构模型,通过对复合电源各种组合匹配效果的对比研究,确定了电池和电容的参数匹配情形。实验结果表明,复合电源实验架构能够满足混合动力客车的动力要求。

Synergic electric supply power（SESP）system with high efficiency, economy and long-life is very important for hybrid electric vehicle（HEV）to play the advantages of energy saving and environmental protection.Based on the systematic analysis of battery, super capacitor and DC/DC converter features and the thought of＂storing energy and compensation the loss＂,this paper designed the structural model of SESP,researched the matching about results various combinations of SESP,and determined the parameter matching of battery and capacitor.The experimental results proved that the experimental model of SESP can satisfy the requirement of the HEV.
