摘要
自放电是碱性蓄电池的一项重要性能指标,而科学、简便地检测方法是保证该指标正常的重要途径。传统的做法是将电池的电量充足,搁置28天后,测其实际容量,计算电池的自放电量,这种方法比较接近实际情况,但在实际生产中严重影响了生产的进度。本文分析了碱性蓄电池自放电与搁置时间的关系,采用同一组样本,搁置7天、14天、28天后,检测其自放电量并进行对比。试验结果表明:碱性蓄电池的自放电量大部分集中在充电后的前7天,因此,在生产中必须详细探索搁置时间与自放电量的对应关系,探索搁置28天与搁置7天、14天自放电的不同。制定搁置7天、14天的自放电标准,节约生产时间,缩短生产周期,加快资金周转。
Self-discharge were a important characteristics guideline of Cd/Ni storage battery.Guideline of self-discharge require scientific and handy method come true.Conventional method were de regie charge at storage battery,place 28 day at normalk temperature,measuring actual electric quantity,and calculate self-discharge,this method be close to physical truth,but serious influence production plan.Relation of self-discharge and place time were analyzed in this paper,self-discharge of place 7 day,14 day and 28 day proceed contrase.The results of expreiment indicated that self-discharge collect at place ahead 7 day,so must detail explore relation of self-discharge and place time,contrast of self-discharge place 28 day,place 7 day and place 14 day.Enactment of rule place 7 day and place 14 day,cut down production time, shorten production cycle,accelerate turnover of capital.
