基于搭载正温度系数热敏电阻(PTC)水加热系统的纯电动样车进行整车低温续驶里程试验,定量研究分析了不同电池加热策略对低温续驶里程的影响.试验结果表明:电池放电量与试验结束电池温度和试验全程电池平均温度均相关,其中试验结束电池温度为主要影响因素;低电量单次电池加热策略优于全程加热策略,且启动加热的荷电状态(SOC)越低,对低温续驶里程的提升效果越好;在低电量单次加热策略中,不同的加热目标温度会影响低温续驶里程,需要选择一个合适的加热目标温度,以达到最佳的低温续驶里程.试验研究结果可以为纯电动汽车的电池热管理控制策略制定和优化提供参考.
Based on a pure electric prototype vehicle equipped with a PTC water heating system,a low-temperature driving range test was conducted to quantitatively analyze the impact of different battery heating strategies on the low-temperature driving range.The test results show that the battery discharge is related to the end of the test battery temperature and the average temperature of the entire test battery,with the end of the test battery temperature being the main influencing factor;The low battery single battery heating strategy is superior to the full range heating strategy,and the lower the SOC when starting the heating,the better the improvement effect on low-temperature driving range;In a low battery single heating strategy,different heating target temperatures will affect the low-temperature range,and it is necessary to choose an appropriate heating target temperature to achieve the optimal low-temperature range.The experi-mental research results can provide reference for the formulation and optimization of battery thermal management control strategies for pure electric vehicles.
