摘　　要：电动汽车在低温环境下会出现充电时间缩短,可用电量降低,续航里程的大幅下降,广受消费者的诟病,由于动力电池既怕冷又怕热,在高温或低温下动力电池的充放电性能都受到严重制约,同时安全性也大受影响。文章主要针对不同温度下电池容量变化、内阻变化、整车运行温度变化、续航里程,能耗等进行实车测试研究、探讨。希望可以对动力蓄电池及电动汽车续航里程的影响因素有一个清晰的认识。Electric vehicles can experience shortened charging time,reduced available power,and a significant decrease in range in low-temperature environments,which is widely criticized by consumers.Due to the fear of both cold and heat,the charging and discharging performance of power batteries is severely restricted at high or low temperatures,and their safety is also greatly affected.The article mainly focuses on the actual vehicle testing research and exploration of battery capacity changes,internal resistance changes,vehicle operating temperature changes,range,energy consumption,etc.under different temperatures.I hope to have a clear understanding of the factors that affect the range of power batteries and electric vehicles.
