摘要
以某搭载磷酸铁锂动力电池系统的轻型商用电动车为研究对象,对比分析了动力电池在低温-10 ℃及常温25 ℃时的充电时间、能量、续航里程、百公里能耗、输出功率。研究了在-10 ℃低温环境下,以 40 km/h 匀速行驶时系统电压及单体温度的变化规律。分析结果为低温环境中纯电动汽车的动力性能研究和电池管理系统低温策略提供依据。
Taking a light commercial electric vehicle equipped with a lithium iron phosphate power battery system as an object, the charging time, energy, cruising range, energy consumption per 100 kilometers, and output power of the power battery at a low temperature of -10 ° C and a normal temperature of 25 ℃ are analyzed. The change law of system voltage and temperature when driving at a constant speed of 40km/h at a low temperature of -10 ℃ is studied. A basis for the low-temperature strategy of the battery management system for the performance of power battery energy storage systems in low-temperature environments is provided.
