一般分為快速充(chong)電(dian)、補(bu)足充(chong)電(dian)、涓流充(chong)電(dian)三個階段。

   快速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)階段：用大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池進行(xing)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)以迅速恢復電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)速率可(ke)以達1C以上，此時充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓較低(di)，但會限制(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在一定數值(zhi)范圍之(zhi)內。

   補(bu)足(zu)充電(dian)(dian)(dian)(dian)(dian)階(jie)段：相(xiang)對于(yu)快(kuai)速(su)(su)充電(dian)(dian)(dian)(dian)(dian)階(jie)段，補(bu)足(zu)充電(dian)(dian)(dian)(dian)(dian)階(jie)段又可以(yi)稱為慢速(su)(su)充電(dian)(dian)(dian)(dian)(dian)階(jie)段。當快(kuai)速(su)(su)充電(dian)(dian)(dian)(dian)(dian)階(jie)段終止時，電(dian)(dian)(dian)(dian)(dian)池并(bing)(bing)未完全充足(zu)，還需加入(ru)補(bu)足(zu)充電(dian)(dian)(dian)(dian)(dian)過(guo)(guo)程，補(bu)足(zu)充電(dian)(dian)(dian)(dian)(dian)速(su)(su)率一般不(bu)超過(guo)(guo)0.3C，因為電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓經過(guo)(guo)快(kuai)速(su)(su)充電(dian)(dian)(dian)(dian)(dian)階(jie)段后有所升高，所以(yi)補(bu)足(zu)充電(dian)(dian)(dian)(dian)(dian)階(jie)段的充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓也應該(gai)有所提(ti)升，并(bing)(bing)且恒定在一定范圍之內。

  涓流充(chong)電(dian)階(jie)段(duan)：在補足充(chong)電(dian)階(jie)段(duan)后(hou)(hou)期，當檢測到溫度(du)上升超(chao)過極限值(zhi)或充(chong)電(dian)電(dian)流減小到一定值(zhi)之(zhi)后(hou)(hou)，開始用更小的(de)電(dian)流進行充(chong)電(dian)直(zhi)至滿足一定的(de)條件后(hou)(hou)結(jie)束充(chong)電(dian)。
