摘　　要：为研究功率型锂离子电池性能,对某35 Ah功率型锂离子电池单体进行了充放电特性试验和分析,由此获得功率型电池在不同温度和不同倍率下的充放电特性、内阻特性和温升特性。研究结果表明,低温下电池的充放电内阻较大,充放电性能衰减显著;常温下电池的内阻较小,充放电温升较小,大电流充放电的容量稳定性好,质量比能量高,作为电传动车辆主要或辅助动力源具有良好的应用前景。To research the performance of high-power lithium-ion battery, the experiments of the charge-discharge characteristics of 35 Ah high-power lithium-ion battery were carried out and analyzed,and the battery＇s characteristics of charge-discharge, internal resistance and temperature were given. The resuh shows the internal resistance is increased and the charge-discharge performance is decreased in the low temperature; the battery has the small internal resistance, the ability to charge and discharge by the high current and high specific energy at normal temperature. This kind of battery has a good application prospect in EVS.
