The invention relates to the field of hybrid electric vehicles, in particular to an energy management method and a plug-in hybrid electric vehicle. The energy management method comprises the steps that whether the temperature of the engine emission aftertreatment device meets the normal work requirement or not is judged; when the requirement of normal work is met, the SOC starting condition of the engine is that the difference value between the real-time SOC value of the battery and the real-time SOC reference value is smaller than a first threshold value; when the requirement of normal work is not met, the SOC starting condition of the engine is that the difference value between the real-time SOC value of the battery and the real-time SOC reference value is smaller than a second threshold value; wherein the second threshold value is larger than the first threshold value, the engine is promoted to be started in advance, so that the engine emission aftertreatment device is heated, and pollutant emission is reduced. According to the energy management method, the starting SOC of the engine is adjusted by judging whether the temperature of the engine emission aftertreatment device meets the normal work requirement or not, the whole vehicle emission amount is effectively reduced, and the purpose of emission reduction is achieved.

    本发明涉及混合动力汽车领域,特别是涉及一种能量管理方法及插电式混合动力汽车。所述能量管理方法包括:判断发动机排放后处理装置的温度是否满足正常工作的要求;当满足正常工作的要求时,发动机的SOC启动条件为所述电池的实时SOC值与实时SOC参考值的差值小于第一阈值;当不满足正常工作的要求时,发动机的SOC启动条件为所述电池的实时SOC值与实时SOC参考值的差值小于第二阈值;其中,所述第二阈值大于所述第一阈值,促使所述发动机提前启动,以加热所述发动机排放后处理装置,减少污染物排放。上述能量管理方法,通过判断所述发动机排放后处理装置的温度是否满足正常工作的要求来调整所述发动机的启动SOC,有效降低整车排放量,达到减排的目的。
