摘要
插电式混合动力汽车(PHEV)的能耗是其性能中的一个重要组成部分。目前中美相关标准中的能耗检测方法对纯电阶段的检测均未考虑库伦效率和充电习惯对其能耗的影响,从而存在相当程度的检测偏差。本文通过对比分析中美标准、分析库伦效率对电耗测试结果的影响、调查国内PHEV车主的充电习惯,改进流程和计算方法,为PHEV能耗测试流程的改进提供参考。
Energy consumption of plug-in hybrid electric vehicles(PHEV) is an important part of its performance. At present, the energy consumption detection methods in the relevant standards of China and the United States have not considered the influence of Coulomb efficiency and charging habits on the energy consumption of pure electricity stage, so there is a considerable degree of detection deviation. Aiming at this problem, this paper provides a reference for the improvement of PHEV energy consumption test flow by comparing and analyzing Chinese and American standards, analyzing the influence of Coulomb efficiency on the test results of electricity consumption, investigating the charging habits of domestic PHEV car owners, and improving the flow and calculation methods.
