电动汽车滑行法与查表法试验对比分析

Comparative analysis of energy consumption between electric vehicle taxiing method and look-up table method

电动汽车的续驶里程与能量消耗率是衡量电动汽车成熟水平的关键指标。《GB/T 18386-2017电动汽车能量消耗率和续驶里程试验》中规定了电动汽车可以选择滑行法与查表法中的任意一种进行续驶里程与能量消耗率的测试。通常情况下,滑行法比查表法更精确,但选择哪种方法更有利于续驶里程结果,与车辆特性密切相关。文章提出一种简便的对比方法,可以快速分析两种方法的能耗差距水平。并给出了不易获取滑行试验数据时,采用查表法如何做近似分析的建议。

The mileage and energy consumption rate of electric vehicles are the key indicators to measure the maturity of electric vehicles.The energy consumption rate and driving mileage test of GB/T 18386-2017 electric vehicle stipulates that the electric vehicle can choose any kind of test of driving mileage and energy consumption rate in the skidding and table lookup method.Usually,the taxi method is more accurate than the look-up table method,but which method is more conducive to the result of the mileage and is closely related to the vehicle characteristics.This paper proposes a simple and convenient method to quickly analyze the energy consumption gap between the two methods.It also gives the suggestion of how to do approximate analysis with the look-up table method when it is not easy to get the test data.
