一般(ban)分為快(kuai)速充(chong)電、補足充(chong)電、涓流充(chong)電三個階段(duan)。

   快(kuai)速(su)充電(dian)階段(duan)：用大電(dian)流對(dui)電(dian)池進行充電(dian)以迅速(su)恢復(fu)電(dian)池電(dian)能，充電(dian)速(su)率(lv)可(ke)以達(da)1C以上(shang)，此時充電(dian)電(dian)壓較(jiao)低，但會限制(zhi)充電(dian)電(dian)流在(zai)一(yi)定數值范圍(wei)之內(nei)。

   補(bu)足(zu)充(chong)(chong)(chong)電(dian)(dian)階(jie)段(duan)(duan)：相對于快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)階(jie)段(duan)(duan)，補(bu)足(zu)充(chong)(chong)(chong)電(dian)(dian)階(jie)段(duan)(duan)又可以稱(cheng)為(wei)慢速(su)充(chong)(chong)(chong)電(dian)(dian)階(jie)段(duan)(duan)。當快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)階(jie)段(duan)(duan)終止時(shi)，電(dian)(dian)池并未完全充(chong)(chong)(chong)足(zu)，還需(xu)加入補(bu)足(zu)充(chong)(chong)(chong)電(dian)(dian)過程，補(bu)足(zu)充(chong)(chong)(chong)電(dian)(dian)速(su)率一般不(bu)超過0.3C，因為(wei)電(dian)(dian)池電(dian)(dian)壓經過快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)階(jie)段(duan)(duan)后有(you)所(suo)(suo)(suo)升(sheng)高(gao)，所(suo)(suo)(suo)以補(bu)足(zu)充(chong)(chong)(chong)電(dian)(dian)階(jie)段(duan)(duan)的充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)壓也(ye)應該有(you)所(suo)(suo)(suo)提(ti)升(sheng)，并且恒定在一定范圍之內。

  涓流充(chong)電階段：在補足充(chong)電階段后期，當檢測到溫度上升超過極限值(zhi)或充(chong)電電流減小到一定值(zhi)之后，開始用更(geng)小的電流進行充(chong)電直至滿足一定的條件(jian)后結(jie)束充(chong)電。
