一般分(fen)為快速充(chong)電、補足充(chong)電、涓流充(chong)電三(san)個階段。

   快(kuai)速(su)(su)充電(dian)(dian)(dian)階段：用大電(dian)(dian)(dian)流對電(dian)(dian)(dian)池進行充電(dian)(dian)(dian)以迅(xun)速(su)(su)恢(hui)復電(dian)(dian)(dian)池電(dian)(dian)(dian)能，充電(dian)(dian)(dian)速(su)(su)率可以達1C以上，此(ci)時充電(dian)(dian)(dian)電(dian)(dian)(dian)壓較低，但會限制充電(dian)(dian)(dian)電(dian)(dian)(dian)流在一定數值范圍之內。

   補(bu)(bu)足充(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)：相對(dui)于快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)，補(bu)(bu)足充(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)又可以稱為慢(man)速充(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)。當快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)終止(zhi)時，電(dian)(dian)(dian)池(chi)并(bing)未完全(quan)充(chong)(chong)(chong)足，還需加入補(bu)(bu)足充(chong)(chong)(chong)電(dian)(dian)(dian)過程，補(bu)(bu)足充(chong)(chong)(chong)電(dian)(dian)(dian)速率一(yi)般(ban)不超過0.3C，因為電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)經過快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)后有所(suo)升高，所(suo)以補(bu)(bu)足充(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)段(duan)的充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)也(ye)應該有所(suo)提升，并(bing)且恒(heng)定在一(yi)定范(fan)圍之內。

  涓(juan)流充(chong)電(dian)階段(duan)(duan)：在(zai)補足(zu)充(chong)電(dian)階段(duan)(duan)后期，當檢(jian)測到溫度(du)上升(sheng)超過極(ji)限(xian)值或(huo)充(chong)電(dian)電(dian)流減小(xiao)到一定(ding)(ding)值之后，開始用更小(xiao)的(de)電(dian)流進(jin)行充(chong)電(dian)直至滿足(zu)一定(ding)(ding)的(de)條(tiao)件后結束充(chong)電(dian)。
