摘要
针对传统恒压充电方式对电池的易损性和低寿命特性,进行了蓄电池最优充电特性曲线的研究.通过对蓄电池恒压充电时电压电流的变化情况进行监测,得到蓄电池充电时电压电流的变化数据,利用不同次数最小二乘法拟合,得到蓄电池电压电流的充电特性曲线.通过分析不同次数下的偏差率得到拟合的最优曲线,为提高蓄电池的使用寿命和智能充电器的研究提供理论依据.
The change curves of voltage and current were studied.Through monitoring the values of constant charging,and using the least square method,the data of the charging voltage and charging current were obtained.By analyzing the rate of the deviation under different times,the best fitting curves were included.It improved the vulnerability and life characteristic of storage battery,thus provided a theoretical basis for the life of the battery and smart charger.
