基于能量流方法的纯电动汽车低温续驶里程提升研究
Research on Improving the Low-Temperature Driving Range of Pure Electric Vehicles Based on the Energy Flow Method
摘要
Abstract
This study focuses on a small-sized electric passenger vehicle equipped with a heat pump system,conducting a driving range test under low-temperature CLTC-P cycle conditions.By comprehensively examining the test data and analyzing the vehicle's energy flow,potential avenues for improving the driving range are explored.A comprehensive model of vehicle dynamics and economics,including the thermal management system,is established on the Amesim platform.After calibration,different optimization schemes are simulated and compared to develop a combined optimization scheme.Experimental results show that the combined optimization scheme can improve the low-temperature driving range by 12.6%.Among them,the contribution of the thermal management system optimization scheme significantly surpasses that of the vehicle resistance optimization scheme and the control strategy optimization scheme.This study provides reference ideas and methods for improving the driving range of pure electric passenger vehicles under low-temperature environments.关键词
