一般分為(wei)快速充電(dian)、補足充電(dian)、涓流(liu)充電(dian)三個階段。

   快速(su)充電(dian)(dian)(dian)階段(duan)：用大電(dian)(dian)(dian)流對電(dian)(dian)(dian)池(chi)(chi)進行充電(dian)(dian)(dian)以迅速(su)恢復電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)能，充電(dian)(dian)(dian)速(su)率可以達1C以上，此時(shi)充電(dian)(dian)(dian)電(dian)(dian)(dian)壓較低，但會限制(zhi)充電(dian)(dian)(dian)電(dian)(dian)(dian)流在(zai)一定數值范(fan)圍之內(nei)。

   補(bu)足(zu)充(chong)(chong)電階(jie)(jie)段(duan)(duan)：相對于(yu)快速(su)充(chong)(chong)電階(jie)(jie)段(duan)(duan)，補(bu)足(zu)充(chong)(chong)電階(jie)(jie)段(duan)(duan)又可以稱為慢(man)速(su)充(chong)(chong)電階(jie)(jie)段(duan)(duan)。當快速(su)充(chong)(chong)電階(jie)(jie)段(duan)(duan)終止時，電池并未完全充(chong)(chong)足(zu)，還需加入補(bu)足(zu)充(chong)(chong)電過程(cheng)，補(bu)足(zu)充(chong)(chong)電速(su)率一(yi)(yi)般不超過0.3C，因為電池電壓經(jing)過快速(su)充(chong)(chong)電階(jie)(jie)段(duan)(duan)后(hou)有所(suo)升(sheng)高，所(suo)以補(bu)足(zu)充(chong)(chong)電階(jie)(jie)段(duan)(duan)的充(chong)(chong)電電壓也應該有所(suo)提升(sheng)，并且恒(heng)定在(zai)一(yi)(yi)定范(fan)圍之內(nei)。

  涓流充(chong)電(dian)(dian)階段：在(zai)補足(zu)充(chong)電(dian)(dian)階段后(hou)(hou)期(qi)，當(dang)檢(jian)測到溫度上升超(chao)過極限值或充(chong)電(dian)(dian)電(dian)(dian)流減小到一(yi)定(ding)值之后(hou)(hou)，開始用(yong)更小的電(dian)(dian)流進(jin)行充(chong)電(dian)(dian)直至滿足(zu)一(yi)定(ding)的條件(jian)后(hou)(hou)結束充(chong)電(dian)(dian)。
