一、常用的幾種充電方式介紹：

        該方式主要應用在(zai)在(zai)線UPS等領域. 鉛酸蓄(xu)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)過程(cheng)分(fen)兩個(ge)階段(duan), 第一(yi)階段(duan)為(wei)(wei)恒流過程(cheng), 電(dian)(dian)(dian)流值一(yi)般(ban)設定(ding)(ding)在(zai)0.3C以(yi)內(nei); 第二階段(duan)為(wei)(wei)恒壓階段(duan), 電(dian)(dian)(dian)壓設定(ding)(ding)在(zai)13.7V左右(以(yi)12V電(dian)(dian)(dian)池為(wei)(wei)例).  對完(wan)(wan)全(quan)放空的(de)電(dian)(dian)(dian)池, 用這種(zhong)(zhong)方法(fa)一(yi)般(ban)需(xu)要40個(ge)小時(shi)(shi)以(yi)上才能完(wan)(wan)全(quan)充(chong)滿電(dian)(dian)(dian)池. 這種(zhong)(zhong)充(chong)電(dian)(dian)(dian)方法(fa)的(de)優點是(shi)電(dian)(dian)(dian)路簡單(dan), 可以(yi)給系(xi)統(tong)并連供電(dian)(dian)(dian), 長(chang)時(shi)(shi)期充(chong)電(dian)(dian)(dian)也無過充(chong)隱患.  不足之處是(shi)充(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)太長(chang). 在(zai)電(dian)(dian)(dian)信和(he)應急照明(ming)系(xi)統(tong)中(zhong),  基本都是(shi)這種(zhong)(zhong)充(chong)電(dian)(dian)(dian)模式.

    主(zhu)要應用于需頻繁充方電的場所(如(ru)電動自行車)

 這是一種改良(liang)的三段式,  其定時均充的目的是降(jiang)低(di)蓄電池異常失水和發熱變形的隱患；

        理(li)(li)論上(shang)講(jiang), 用(yong)正(zheng)負(fu)脈沖方式充(chong)電(dian)(dian)有助于(yu)降(jiang)低電(dian)(dian)池(chi)充(chong)電(dian)(dian)過(guo)程中的”硫化(hua)”和”極化(hua)”現象, 增加正(zheng)負(fu)極氫(qing)氧氣體(ti)的復(fu)合(he)率, 減少電(dian)(dian)池(chi)失水. 但是具體(ti)量化(hua)的效(xiao)果(guo)到目(mu)前(qian)(qian)為止在國際上(shang)仍(reng)有較大(da)爭議.  這(zhe)種(zhong)理(li)(li)論最(zui)早(zao)在上(shang)世(shi)紀(ji)60年代已經(jing)出現, 到目(mu)前(qian)(qian)爭議仍(reng)然較大(da).   盡管對正(zheng)負(fu)脈沖的效(xiao)果(guo)有爭議, 但大(da)家都(dou)一直(zhi)承認(ren): 合(he)理(li)(li)的運(yun)用(yong)脈沖充(chong)電(dian)(dian)方式對電(dian)(dian)池(chi)本身(shen)并沒有明顯的不(bu)良后果(guo).
