摘要
本文以重型纯电动汽车为研究对象,分别在高温和低温环境条件下开展能量消耗量和续驶里程试验,研究阻力设定的合理方法,确保试验结果的合理性和可靠性,以真实反映不同环境条件对车辆能量消耗量及续驶里程的影响。基于验证试验结果分析,得出替代阻力计算方法:在常温滑行阻力或推荐阻力的基础上增加10%得到低温环境的替代阻力,在常温滑行阻力或推荐阻力的基础上降低5%得到高温环境的替代阻力。
This paper takes heavy-duty pure electric vehicles as the research objects and conducts energy consumption and driving range tests under high and low temperature environments.It investigates the appropriate method for resistance setting to ensure the rationality and reliability of test results,which accurately reflect the impact of different environmental conditions on energy consumption and driving range.Based on the analysis of the validation test results,the following calculation method for determining alternative resistance is proposed:Increase the sliding resistance or the recommended resistance in a normal-temperature environment by 10%to obtain the alternative resistance for a low-temperature environment and decrease it by 5%to obtain the alternative resistance for a high-temperature environment.
