1、恒定電(dian)(dian)流充(chong)電(dian)(dian)法

在(zai)充電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)(guo)程(cheng)中充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)始(shi)終保持(chi)不(bu)(bu)變(bian)(bian)(bian)，叫(jiao)做恒定電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)法(fa)(fa)，簡(jian)稱恒流(liu)(liu)(liu)(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)法(fa)(fa)或等流(liu)(liu)(liu)(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)法(fa)(fa)。在(zai)充電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)(guo)程(cheng)中由(you)于蓄電(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)壓逐(zhu)漸升高，充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)逐(zhu)漸下(xia)降(jiang)，為保持(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)不(bu)(bu)致因蓄電(dian)(dian)(dian)(dian)(dian)(dian)池端電(dian)(dian)(dian)(dian)(dian)(dian)壓升高而減(jian)小，充電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)(guo)程(cheng)必須逐(zhu)漸升高電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)壓，以維(wei)持(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)始(shi)終不(bu)(bu)變(bian)(bian)(bian)，這對于充電(dian)(dian)(dian)(dian)(dian)(dian)設備的自動化程(cheng)度要求較高，一般簡(jian)陋的充電(dian)(dian)(dian)(dian)(dian)(dian)設備是不(bu)(bu)能(neng)滿足恒流(liu)(liu)(liu)(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)要求的。恒流(liu)(liu)(liu)(liu)(liu)充電(dian)(dian)(dian)(dian)(dian)(dian)法(fa)(fa)，在(zai)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池最大(da)答應的充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)情況下(xia)，充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)越大(da)，充電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間就可以縮短。若從時(shi)間上(shang)考慮，采用此(ci)法(fa)(fa)有利(li)的。但在(zai)充電(dian)(dian)(dian)(dian)(dian)(dian)后(hou)期(qi)若充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)仍不(bu)(bu)變(bian)(bian)(bian)，這時(shi)由(you)于大(da)部分電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)用于電(dian)(dian)(dian)(dian)(dian)(dian)解水上(shang)，電(dian)(dian)(dian)(dian)(dian)(dian)解液出氣泡過(guo)(guo)多而顯(xian)沸騰狀，這不(bu)(bu)僅消耗電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)，而且(qie)輕易使極(ji)板(ban)上(shang)活性物(wu)質大(da)量脫落，溫升過(guo)(guo)高，造(zao)成極(ji)板(ban)彎(wan)曲，容量迅速下(xia)降(jiang)而提前報廢。所以，這種充電(dian)(dian)(dian)(dian)(dian)(dian)方法(fa)(fa)很少(shao)采用。

3、有固定電(dian)阻的恒定電(dian)壓充電(dian)

為(wei)補救(jiu)恒定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)缺點而采用的(de)一種方法。即在(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池之間串聯一電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻，這樣充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)初期(qi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流可(ke)以調整。但有(you)時(shi)最大(da)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流受到限制，因此隨充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程的(de)進(jin)行，蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)逐漸(jian)上(shang)升(sheng)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流卻(que)幾乎(hu)成為(wei)直線衰減。有(you)時(shi)使用兩個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)，約在(zai)2.4V時(shi)，從低電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻轉換(huan)到高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻，以減少出(chu)氣。

4、階段(duan)等(deng)流充電法

綜(zong)合恒(heng)流(liu)(liu)(liu)和恒(heng)壓充(chong)電(dian)(dian)(dian)法(fa)的特點，蓄(xu)電(dian)(dian)(dian)池(chi)在(zai)充(chong)電(dian)(dian)(dian)初期用較(jiao)大(da)的電(dian)(dian)(dian)流(liu)(liu)(liu)，經過一段(duan)(duan)(duan)(duan)時間改(gai)用較(jiao)小的電(dian)(dian)(dian)流(liu)(liu)(liu)，至充(chong)電(dian)(dian)(dian)后期改(gai)用更小的電(dian)(dian)(dian)流(liu)(liu)(liu)，即不同階(jie)(jie)段(duan)(duan)(duan)(duan)內以不同的電(dian)(dian)(dian)流(liu)(liu)(liu)進行(xing)恒(heng)流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)的方法(fa)，叫做階(jie)(jie)段(duan)(duan)(duan)(duan)恒(heng)流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)法(fa)。階(jie)(jie)段(duan)(duan)(duan)(duan)恒(heng)流(liu)(liu)(liu)充(chong)電(dian)(dian)(dian)法(fa)，一般可(ke)分為兩個階(jie)(jie)段(duan)(duan)(duan)(duan)進行(xing)，也可(ke)分為多個階(jie)(jie)段(duan)(duan)(duan)(duan)進行(xing)。

階段等流充(chong)(chong)電(dian)(dian)(dian)(dian)法(fa)所需(xu)充(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間短(duan)，充(chong)(chong)電(dian)(dian)(dian)(dian)效果(guo)也好(hao)。由于充(chong)(chong)電(dian)(dian)(dian)(dian)后期改用(yong)較小電(dian)(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)(dian)，這樣(yang)減少(shao)(shao)了(le)氣泡(pao)對(dui)極(ji)板活性(xing)物質的沖洗，減少(shao)(shao)了(le)活性(xing)物質的脫落。這種充(chong)(chong)電(dian)(dian)(dian)(dian)法(fa)能延長(chang)蓄電(dian)(dian)(dian)(dian)池(chi)使(shi)用(yong)壽命，并節省電(dian)(dian)(dian)(dian)能，充(chong)(chong)電(dian)(dian)(dian)(dian)又徹底，所以(yi)是當前(qian)常用(yong)的一(yi)種充(chong)(chong)電(dian)(dian)(dian)(dian)方法(fa)。一(yi)般蓄電(dian)(dian)(dian)(dian)池(chi)第一(yi)階段以(yi)10h率(lv)電(dian)(dian)(dian)(dian)流進行充(chong)(chong)電(dian)(dian)(dian)(dian)，第二階段以(yi)20h率(lv)電(dian)(dian)(dian)(dian)流進行充(chong)(chong)電(dian)(dian)(dian)(dian)。各(ge)階段充(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間的是非(fei)，各(ge)種蓄電(dian)(dian)(dian)(dian)池(chi)的具體要求和標準不一(yi)樣(yang)。
