一般分為(wei)快速充電(dian)、補足(zu)充電(dian)、涓(juan)流(liu)充電(dian)三個階段(duan)。

   快速充(chong)電(dian)(dian)階(jie)段：用大電(dian)(dian)流(liu)對電(dian)(dian)池進行充(chong)電(dian)(dian)以迅速恢復電(dian)(dian)池電(dian)(dian)能，充(chong)電(dian)(dian)速率可以達1C以上，此(ci)時充(chong)電(dian)(dian)電(dian)(dian)壓較低，但會限制充(chong)電(dian)(dian)電(dian)(dian)流(liu)在一定數值范圍之(zhi)內。

   補足(zu)(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)階段(duan)(duan)(duan)：相對于快(kuai)速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)階段(duan)(duan)(duan)，補足(zu)(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)階段(duan)(duan)(duan)又可(ke)以(yi)稱為慢速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)階段(duan)(duan)(duan)。當快(kuai)速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)階段(duan)(duan)(duan)終止時(shi)，電(dian)(dian)(dian)(dian)池并未完全充(chong)(chong)(chong)(chong)足(zu)(zu)(zu)，還需加入補足(zu)(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)過(guo)程，補足(zu)(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)速(su)率一般不超過(guo)0.3C，因為電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓(ya)經過(guo)快(kuai)速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)階段(duan)(duan)(duan)后有所(suo)升高，所(suo)以(yi)補足(zu)(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)階段(duan)(duan)(duan)的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)也應該有所(suo)提升，并且恒定在一定范圍之內。

  涓流充(chong)(chong)(chong)(chong)電階段：在補(bu)足(zu)充(chong)(chong)(chong)(chong)電階段后期，當檢測到(dao)(dao)溫度上升超過極(ji)限(xian)值或充(chong)(chong)(chong)(chong)電電流減小到(dao)(dao)一(yi)(yi)定值之后，開始用更小的電流進行(xing)充(chong)(chong)(chong)(chong)電直至滿足(zu)一(yi)(yi)定的條件后結束(shu)充(chong)(chong)(chong)(chong)電。
