The plug-in hybrid electric vehicle not only has the advantages of low emissions from electric vehicles, but also takes advantage of the high specific energy and high specific power of petroleum fuels, which can significantly improve the emissions and fuel economy of traditional vehicles. Studying its comprehensive energy consumption evaluation method is an important part of analyzing the economics of plug-in hybrid electric vehicles. This paper first puts forward the concept of statistical energy consumption and then proposes an innovative calculation method of plug-in hybrid electric vehicle energy consumption based on statistical energy consumption by referring to and analyzing the energy consumption test regulations of the United States, the European Union, and China. Given the two use case assumptions of charge depleting mode priority and charge sustaining mode only, considering the fuel consumption and the energy consumption that converts electrical energy consumption to fuel consumption, the probability density function of travel mileage distribution and energy consumption is derived. Finally, the interpretation and analysis of statistical energy consumption evaluation results are carried out.
插电式混合动力汽车不仅具有电动汽车低排放的优点,还利用了石油燃料的高比能量和高比功率,能够显著改善传统车辆的排放和燃油经济性。研究其综合能耗评估方法是分析插电式混合动力汽车经济性的重要组成部分。本文首先提出统计能耗的概念,然后通过参考和分析美国、欧盟及中国的能耗测试法规,提出一种基于统计能耗的插电式混合动力汽车能耗创新计算方法。针对电量消耗模式优先和仅电量维持模式这两种用例假设,考虑燃料消耗以及将电能消耗转换为燃料消耗的能耗,推导出行程里程分布和能耗的概率密度函数。最后,对统计能耗评估结果进行解读与分析。
