电机效率对混合动力汽车燃油经济性影响研究

Influences of Motor Efficiency on Fuel Economy of HEV

简述了混合动力汽车中的类型、运行模式和节能机理。以双轴并联混合动力汽车为例,采用ADVISOR仿真软件分析了电机效率提高和高效区扩大对混合动力汽车燃油经济性的影响,得出电机效率特性的改善可以在混合动力技术改善汽车燃油经济性的基础上,进一步改善燃油经济性的结论。最后,分析了从电机本体设计和控制方面提高电机运行效率的途径。

Motor plays an important role in hybrid electric vehicle techniques. Taking an example for two-axle parallel hybrid electric vehicle, advanced vehicle simulation software, ADVISOR, was used to analyze the effect of motor efficiency improvement and high-efficient zone expansion on the fuel economy of HEV. The conclusion is that the change can improve the fuel economy of HEV more. At last, the ways to improve the efficiency of motor were introduced.
