温度、SOC对铁锂电池存储性能的影响
|
Abstract:
对塑壳100 Ah铁锂电池进行存储性能测试，考察了温度、SOC (荷电状态)等因素对磷酸铁锂动力电池存储性能的影响。结果表明，相同的存储时间，不同的温度和不同SOC对电池的存储影响各不相同，55℃对电池的容量衰减影响最大，而0%和100% SOC均不是最有利电池性能发挥的最佳荷电状态，综合各种因素，考察了磷酸铁锂电池的最佳存储条件。
The storage performance of plastic case 100 Ah lithium iron battery was tested, and the effects of temperature, SOC (state of charge) and other factors on the storage performance of lithium iron phosphate power battery were investigated. The results show that different temperatures and SOC have different effects on the storage of batteries with the same storage time. The capacity attenua-tion of batteries is greatest at 55℃, while 0% and 100% SOC are not the best charging conditions for the performance of batteries. Combined with various factors, the optimum storage conditions of lithium iron phosphate batteries were investigated.
