插电式混合动力汽车能耗研究

Research on Energy Consumption of Plug-In Hybrid Electric Vehicles

摘要: 本文选取了不同车型的插电式混合动力汽车开展能耗特性研究，依据GB/T 19753-2021和GB 18352.6-2016要求进行电量消耗和电量保持模式下的能耗测试，重点探究了车辆测试质量和电池容量在WLTC测试循环下的电量消耗量和燃油消耗量，研究发现车辆在CS和CD模式下的油耗和综合油耗均随着车辆测试质量增大而增大，此外，车辆综合电耗随着车辆电池容量的增大而增大，而随着车辆测试质量的增大没有明显变化趋势。

Abstract: This study investigates the energy consumption characteristics of plug-in hybrid electric vehicles (PHEVs) across different models. Energy consumption tests were conducted in both power consumption and power retention modes according to GB/T 19753-2021 and GB 18352.6-2016 requirements. The research focuses on analyzing the relationship between vehicle test mass and battery capacity in terms of power consumption and fuel consumption under the WLTC test cycle. Findings reveal that both fuel consumption in CS and CD modes and overall fuel consumption increase with rising vehicle test mass. Additionally, overall electrical energy consumption grows with larger battery capacity but shows no significant trend with increasing vehicle test mass.
