一(yi)般分為快速充電(dian)(dian)、補(bu)足充電(dian)(dian)、涓流充電(dian)(dian)三個階(jie)段。

   快速充(chong)電(dian)(dian)(dian)(dian)階(jie)段：用大電(dian)(dian)(dian)(dian)流(liu)對電(dian)(dian)(dian)(dian)池(chi)進行充(chong)電(dian)(dian)(dian)(dian)以(yi)迅速恢(hui)復電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)能(neng)，充(chong)電(dian)(dian)(dian)(dian)速率(lv)可以(yi)達(da)1C以(yi)上，此時充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓較(jiao)低(di)，但會限制充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)在(zai)一定數值范(fan)圍之(zhi)內。

   補足(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)(jie)段(duan)：相(xiang)對于快(kuai)速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)(jie)段(duan)，補足(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)(jie)段(duan)又可以稱為(wei)慢(man)速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)(jie)段(duan)。當快(kuai)速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)(jie)段(duan)終止時(shi)，電(dian)(dian)(dian)池并未完全充(chong)(chong)(chong)(chong)足(zu)(zu)，還需(xu)加入補足(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)過程，補足(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)速(su)率一般不(bu)超過0.3C，因為(wei)電(dian)(dian)(dian)池電(dian)(dian)(dian)壓經過快(kuai)速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)(jie)段(duan)后(hou)有所升高，所以補足(zu)(zu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)階(jie)(jie)段(duan)的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓也應(ying)該(gai)有所提升，并且恒(heng)定(ding)在一定(ding)范圍之(zhi)內。

  涓(juan)流充(chong)(chong)電(dian)階(jie)段(duan)：在補足充(chong)(chong)電(dian)階(jie)段(duan)后(hou)期，當檢測到溫(wen)度上升超(chao)過極(ji)限值或充(chong)(chong)電(dian)電(dian)流減小到一定值之(zhi)后(hou)，開(kai)始用更小的電(dian)流進(jin)行充(chong)(chong)電(dian)直至(zhi)滿(man)足一定的條件后(hou)結束充(chong)(chong)電(dian)。
