Abstract: Energy feedback can effectively improve the cruising range of new energy vehicles. This article takes the coasting feedback energy recovery system of a battery electric vehicle as the research object, and measures the cruising range of the vehicle under different feedback intensity under world light vehicle test cycle (WLTC) condition, and analyzes the influence of coasting feedback intensity on the energy consumption of the vehicle. The experimental results show that with the increase of the coasting feedback intensity, the energy consumption of the vehicle is gradually reduced first. When the coasting feedback intensity increases to a certain extent, the energy consumption no longer decreases, instead of it will be increases with the increase of the coasting feedback intensity.

Key words: New energy vehicle; Energy feedback; Feedback intensity; Energy consumption

摘要： 能量回馈可以有效提高新能源汽车的续航里程，文章以某款纯电动车的滑行回馈能量 回收系统为研究对象，在世界轻型汽车测试循环（WLTC）工况下，测量不同回馈强度下整车 的续航里程，分析滑行回馈强度对整车能耗的影响。实验结果表明，随着滑行回馈强度的增 大，整车能耗先逐渐减低，当滑行回馈强度增大至一定程度之后，能耗不再减低，反而随着 滑行回馈强度的增大而增加。
