摘要
在25℃和-5℃下,采用极限电流对铅酸电池充放电特性进行研究,基于电池表面温度,对生热情况进行分析。结果显示:在低温下,极限充电电流在一定程度上提升了电池的放电容量,同时,短时间的放电脉冲可缓解电池的极化效应。
The charge-discharge characteristics of lead-acid battery were studied by extreme current test at 25℃ and - 5 ℃, the heat generation (which helped to improve the low-temperature performance) was analyzed based on variations of battery surface temperature. The result showed that the discharge capacity of the battery was promoted by the extreme charge current under low temperature, meanwhile, the polarization effect of the battery was relieved by transient discharge pulses.
