一、對于六段式(shi)充(chong)電(dian)原理及過(guo)程如下(xia)：

　　1）預充階段（小電流預充電）：充電機設有延時啟動，延時時間為7秒，啟動后首先進入預充階段，充電機先設小電流流為目的是激活電池；
　　2）大電流階段（恒流充電）：預充結束后進入恒流電流充電階段；
　　3）恒壓階段（恒壓充電）：當充電電壓上升到入恒壓充電階段，充電電流逐步減小；
　　4）小電流階段（涓流充電）：當充電電流減小到進入小電流階段，恒流充充電，充電電壓小幅上升；
　　5）脈沖階段（脈沖充電）：當充電電壓上升到進入脈沖充電階段，如果充電電壓鐘未達自動進入脈沖階段，池進行補充和維護；
　　6）浮(fu)充(chong)(chong)階段（浮(fu)充(chong)(chong)充(chong)(chong)電）：脈(mo)沖充(chong)(chong)電自動進入浮(fu)充(chong)(chong)階段，浮(fu)充(chong)(chong)階段充(chong)(chong)電機自動關(guan)機。

二、對于(yu)三段式充電(dian)原理(li)及(ji)過(guo)程

  不論哪種充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機，都必須(xu)要求正確使(shi)用(yong)和操作：充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器的正確操作是(shi)：充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，先(xian)(xian)插(cha)電(dian)(dian)(dian)(dian)(dian)(dian)池，后(hou)加(jia)市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)；充(chong)(chong)(chong)(chong)足后(hou)，先(xian)(xian)切斷市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)，后(hou)拔電(dian)(dian)(dian)(dian)(dian)(dian)池插(cha)頭。如(ru)果在充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)先(xian)(xian)拔電(dian)(dian)(dian)(dian)(dian)(dian)池插(cha)頭，特別是(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流大(da)時(shi)，非常容易損(sun)壞充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器。
