电量平衡值对插电式混合动力汽车排放和能耗的影响

The effect of the electricity balance on the emissions and energy consumption of plug-in hybrid vehicles

对插电式混合动力电动汽车进行工况法测试,分析电量平衡值对排放和能耗的影响。结果显示,条件A(储能装置处于最高荷电状态)试验中,按照选项一(单次循环)进行试验,发动机在整个试验过程中未启动,排气污染物排放为零,二氧化碳排放也为零;条件B(储能装置处于最低荷电状态)试验下,电量平衡值对排放无明显影响,对燃料消耗量和二氧化碳排放量有显著影响,呈负线性相关,对电能消耗量有明显影响,呈正线性相关,但电量平衡值不能反映电能消耗水平,电能消耗水平受车辆控制策略、充电效率等影响较大。

The working condition test of the plug-in hybrid electric vehicle is carried out to analyze the influence of the electricity balance on emissions and energy consumption.The results show that in the condition A test,the test is carried out according to option one(single cycle),the engine is not started during the whole test process,the exhaust pollutant emissions are zero,and the carbon dioxide emissions are also zero.Under the condition B test,the balance value has no significant impact on emissions,and has a significant impact on fuel consumption and CO2 emissions with a negative linear correlation.The balance value has a significant impact on the amount of electricity consumed,and is positively linear.However,the electricity balance does not reflect the level of power consumption.The level of power consumption is greatly affected by vehicle control strategies and charging efficiency.
