电动汽车用锂离子电池热特性试验研究

摘要

In order to study the thermal characteristics of 3200 mA·h, 3. 67 V cylindrical ternary material lithium battery, the charge/discharge thermal characteristics test at different temperature and charge/discharge rate were carried out. The test results show that the battery temperature rises rapidly with the increase of charge-discharge current and the decrease of the ambient temperature, and heating lithium-ion under low-temperature can improve the charge/discharge performance of lithium-ion batteries.%为研究锂离子电池的热特性,以3200 mA·h、3.67 V圆柱形三元材料锂电池为研究对象,进行了不同温度、不同充/放电倍率的热特性试验和低温加热试验.试验结果表明:随着充/放电电流的增大以及环境温度的降低,电池温度快速升高,低温下加热可以提高锂离子电池的充/放电性能.
