Research on Cryogenic Properties of NCM Batteries
摘要
Abstract
To study the cryogenic properties of NCM batteries,domestic 37Ah batteries serve as the research objects.The paper aims to study the properties of the NCM batteries such as the charge-dis-charge,resistance and capacity under different ambient temperatures.The results indicate that when the ambient temperature is below 0 ℃,the charge-discharge performance of the battery drops substantially and the internal resistances increases significantly.When below -10 ℃,the charging-discharging volt-age curve shows a nonlinear change and the change of resistance is drastic,which severely impacts the bat-tery life.When below -20 ℃,high-rate discharge cannot be achieved.When below -30 ℃,high and low-rate discharge cannot be achieved and the charging capacity decreases greatly.关键词
