一、常用的幾種充電方式介紹：

        該(gai)方(fang)式主要應用(yong)(yong)在在線UPS等領(ling)域. 鉛(qian)酸蓄電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)過(guo)程分兩(liang)個階(jie)段, 第(di)一階(jie)段為恒流過(guo)程, 電(dian)(dian)(dian)(dian)(dian)流值一般設定在0.3C以(yi)內; 第(di)二階(jie)段為恒壓(ya)階(jie)段, 電(dian)(dian)(dian)(dian)(dian)壓(ya)設定在13.7V左右(you)(以(yi)12V電(dian)(dian)(dian)(dian)(dian)池(chi)為例).  對完全放空(kong)的電(dian)(dian)(dian)(dian)(dian)池(chi), 用(yong)(yong)這(zhe)種(zhong)方(fang)法一般需(xu)要40個小時以(yi)上才(cai)能完全充(chong)(chong)(chong)(chong)滿電(dian)(dian)(dian)(dian)(dian)池(chi). 這(zhe)種(zhong)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方(fang)法的優點是電(dian)(dian)(dian)(dian)(dian)路簡單, 可以(yi)給系(xi)統(tong)并連(lian)供電(dian)(dian)(dian)(dian)(dian), 長時期充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)也無過(guo)充(chong)(chong)(chong)(chong)隱患.  不(bu)足之處是充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間(jian)太(tai)長. 在電(dian)(dian)(dian)(dian)(dian)信和應急照明(ming)系(xi)統(tong)中,  基本(ben)都是這(zhe)種(zhong)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)模式.

    主要應用于需頻繁(fan)充方電的(de)場所(如電動(dong)自行(xing)車)

 這是一種改良的三段式,  其定時均充的目的是降低(di)蓄(xu)電池異常失水和(he)發熱變形的隱患；

        理(li)論上講, 用正負脈沖(chong)方(fang)式充電有助(zhu)于降低電池充電過(guo)程中的(de)(de)”硫化(hua)”和”極化(hua)”現象(xiang), 增(zeng)加正負極氫(qing)氧氣體(ti)的(de)(de)復(fu)合率, 減少電池失(shi)水. 但是具體(ti)量化(hua)的(de)(de)效(xiao)果到(dao)目前(qian)為止在國(guo)際(ji)上仍(reng)有較大(da)爭(zheng)議.  這(zhe)種理(li)論最早在上世紀60年(nian)代已經(jing)出現, 到(dao)目前(qian)爭(zheng)議仍(reng)然較大(da).   盡管對(dui)正負脈沖(chong)的(de)(de)效(xiao)果有爭(zheng)議, 但大(da)家都(dou)一(yi)直承認: 合理(li)的(de)(de)運用脈沖(chong)充電方(fang)式對(dui)電池本身并沒有明(ming)顯的(de)(de)不(bu)良后果.
