锂电电池过充过放的常见诱发场景

在惠州本地的仓储、制造、物流等场景中,电动叉车的日均使用时长普遍较长,不少操作人员为了赶生产进度,经常在电池未完全充满的状态下就高强度启动作业,或是为了省事直接将电池插上电源后连续放置数天不中断充电,这类操作非常普遍,大部分使用者并未意识到这类不规范操作给锂电电池带来的长期损耗。

过充过放带来的实际使用危害

锂电电池出现过充情况时,内部电芯会触发不必要的副反应,电解液受热分解产生大量气体,轻则出现电池外壳鼓包变形,重则会降低内部绝缘性能,带来不必要的安全隐患。而长期过放操作会直接造成电芯内部活性物质的不可逆损耗,大幅缩减电池的循环使用寿命,原本设计使用寿命较长的锂电电池,可能在不到正常使用周期一半的时间里,容量就衰减到额定值的七成以下,直接抬高企业的设备替换成本,不少惠州本地的中小生产企业都曾因忽略这类问题产生过不必要的额外开支。

日常使用的科学预防措施

首先企业要划定专门的叉车充电区域,对上岗操作人员做基础的电池操作规范培训,明确充电流程,电池完全充满后第一时间断开电源,避免长时间的无效浮充。日常作业过程中,尽量不要等电池电量耗尽到个位数百分比才补电,剩余电量处于20%到30%区间时就可以安排接入充电。每隔一周要安排人员对在役的叉车锂电电池做外观巡检,发现外壳异常发热、鼓包等情况要立刻暂停使用,联系专业技术人员上门检测排查。
