一般分為快速充(chong)電、補足(zu)充(chong)電、涓流充(chong)電三個階段。

   快速(su)充(chong)(chong)電(dian)(dian)階段(duan)：用大電(dian)(dian)流對(dui)電(dian)(dian)池進(jin)行充(chong)(chong)電(dian)(dian)以(yi)(yi)迅速(su)恢復(fu)電(dian)(dian)池電(dian)(dian)能，充(chong)(chong)電(dian)(dian)速(su)率可以(yi)(yi)達1C以(yi)(yi)上(shang)，此(ci)時充(chong)(chong)電(dian)(dian)電(dian)(dian)壓較(jiao)低(di)，但(dan)會限制充(chong)(chong)電(dian)(dian)電(dian)(dian)流在一(yi)定數值范(fan)圍之內。

   補(bu)(bu)足(zu)充(chong)(chong)(chong)電階(jie)(jie)段(duan)(duan)(duan)：相(xiang)對于(yu)快速(su)充(chong)(chong)(chong)電階(jie)(jie)段(duan)(duan)(duan)，補(bu)(bu)足(zu)充(chong)(chong)(chong)電階(jie)(jie)段(duan)(duan)(duan)又可以稱為慢速(su)充(chong)(chong)(chong)電階(jie)(jie)段(duan)(duan)(duan)。當快速(su)充(chong)(chong)(chong)電階(jie)(jie)段(duan)(duan)(duan)終止時，電池(chi)并未完(wan)全(quan)充(chong)(chong)(chong)足(zu)，還需加入(ru)補(bu)(bu)足(zu)充(chong)(chong)(chong)電過(guo)程，補(bu)(bu)足(zu)充(chong)(chong)(chong)電速(su)率(lv)一(yi)般不超過(guo)0.3C，因為電池(chi)電壓經過(guo)快速(su)充(chong)(chong)(chong)電階(jie)(jie)段(duan)(duan)(duan)后有(you)所升(sheng)高，所以補(bu)(bu)足(zu)充(chong)(chong)(chong)電階(jie)(jie)段(duan)(duan)(duan)的充(chong)(chong)(chong)電電壓也應該有(you)所提(ti)升(sheng)，并且恒定在一(yi)定范(fan)圍之(zhi)內(nei)。

  涓(juan)流充(chong)(chong)電階段(duan)(duan)：在補足(zu)充(chong)(chong)電階段(duan)(duan)后期(qi)，當檢(jian)測到(dao)溫(wen)度(du)上(shang)升超(chao)過(guo)極限值(zhi)或充(chong)(chong)電電流減小(xiao)到(dao)一(yi)(yi)定值(zhi)之后，開始用(yong)更小(xiao)的電流進行充(chong)(chong)電直至(zhi)滿(man)足(zu)一(yi)(yi)定的條件后結(jie)束充(chong)(chong)電。
