The invention discloses a parameter matching method for a power assembly of an extended-range electric vehicle. The parameter matching method comprises the following steps: step 1, parameter matching of a driving motor; 2, parameter matching of a power battery; and step 3, parameter matching of a range extender. According to the method, accurate and comprehensive parameter matching is carried out on power assembly parts, including the driving motor, the power battery and the range extender, of the range-extended electric vehicle, so that parameters of related parts are relatively optimized; and through matching design of parameters of the power assembly parts, the power performance and the fuel economy of the whole vehicle are comprehensively optimized.

    本发明公开了一种增程式电动汽车动力总成参数匹配方法,包括:步骤一、驱动电机的参数匹配;步骤二、动力电池的参数匹配;步骤三、增程器的参数匹配。本发明对增程式电动汽车的动力总成部件,包括驱动电机、动力电池、增程器,进行准确全面的参数匹配,使相关部件的参数相对最优化;通过对动力总成部件参数的匹配设计,使整车的动力性和燃油经济性达到综合最优化。
