混合动力电动汽车测试方法

在满足常规车辆测试指标的前提下，混合动力汽车能更好地体现节能减排的优势。根据动力总成结构特点和布置方式的不同，介绍了混合动力汽车（HEV）串联式、并联式和混联式3种类型的工作原理，比较分析了混合动力汽车4种常用的整车性能评价测试方法及试验内容。从整车和部件的角度出发，列举了混合动力汽车相关标准中规定的性能评价测试指标。指出混合动力汽车在整车和关键零部件测试时，应先满足常规性能要求，然后对排放和燃油经济性进行评价。

Test Method of Hybrid Electric Vehicle

Under the premise of satisfying normal vehicle test target, hybrid electric vehicle （HEV） has a better advantage in energy conservation and emission reduction. According to the different structural features and layouts of power train, three working principles of HEV are introduced in this paper, including series, parallel, and combined ones. At the same time, four types of HEV performance test evaluation targets are compared and analyzed. Finally, HEV performance criterion is expounded from the perspective of complete vehicle and components. This paper points out that the normal performance of HEV should be satisfied first when the test of HEV＇s complete vehicle and key components is conducted. And then we can evaluate the emission and fuel economy.
