摘要
为了探讨循环寿命对电池性能的影响,以一台磷酸铁锂电池(LIPB)作为研究对象,分析其工作原理。电池性能主要受循环寿命的影响,且循环寿命又主要受放电时间、容量、能量的影响。依据模糊综合评判和模糊关系合成方法对电池在充放电时间、容量、能量中性能进行评判,得出电池系统中的模糊综合评判模型,进一步确定最佳循环周期以完成对电池性能的估计。
In order to investigate the influence of cycle life on the performance of the battery,a lithium iron phosphate battery（LIPB） is used as the research object to analyze its working principle. The battery performance is mainly affected by the cycle life,and the cycle life is mainly affected by the discharge time,capacity and energy. Based on fuzzy comprehensive evaluation method in this paper,the performance of the battery in charging and discharging time,capacity and energy are evaluated,obtaining fuzzy comprehensive evaluation model of the cell system and further determining the optimal cycle to complete the estimation performance of the battery.
