　　定期檢查各單(dan)(dan)元(yuan)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)端電(dian)(dian)(dian)(dian)(dian)壓(ya)和內阻。對12V單(dan)(dan)元(yuan)電(dian)(dian)(dian)(dian)(dian)池(chi)來說，在檢查中如果發現(xian)各單(dan)(dan)元(yuan)電(dian)(dian)(dian)(dian)(dian)池(chi)間的(de)端電(dian)(dian)(dian)(dian)(dian)壓(ya)差超過(guo)(guo)0.4V以(yi)上或電(dian)(dian)(dian)(dian)(dian)他的(de)內阻超過(guo)(guo)80mΩ以(yi)上時，應該對各單(dan)(dan)元(yuan)電(dian)(dian)(dian)(dian)(dian)池(chi)進行均衡(heng)充(chong)電(dian)(dian)(dian)(dian)(dian)，以(yi)恢復電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)內阻和消除各單(dan)(dan)元(yuan)電(dian)(dian)(dian)(dian)(dian)池(chi)之間的(de)端電(dian)(dian)(dian)(dian)(dian)壓(ya)不平衡(heng)。均衡(heng)充(chong)電(dian)(dian)(dian)(dian)(dian)時充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)取13.5～13.8V即可。經過(guo)(guo)良好(hao)均衡(heng)充(chong)電(dian)(dian)(dian)(dian)(dian)處理的(de)電(dian)(dian)(dian)(dian)(dian)池(chi)絕大多數(shu)都可將其內阻恢復到30mΩ以(yi)下。

　　UPS電(dian)源(yuan)在運行過程中(zhong)，由于各單元電(dian)池(chi)特性(xing)隨(sui)時(shi)間變(bian)化而(er)產生的(de)上述不(bu)均(jun)衡(heng)性(xing)是(shi)不(bu)可(ke)能(neng)再(zai)依靠UPS電(dian)源(yuan)內(nei)部的(de)充(chong)電(dian)回路來(lai)消(xiao)除的(de)，所(suo)以(yi)對(dui)這種特性(xing)已(yi)發(fa)生明(ming)顯不(bu)均(jun)衡(heng)性(xing)的(de)電(dian)池(chi)組，若不(bu)及時(shi)采取脫(tuo)機均(jun)充(chong)處理的(de)話，其(qi)不(bu)均(jun)衡(heng)度(du)就會越來(lai)越嚴重。

重新浮充

　　電(dian)(dian)(dian)(dian)(dian)他(ta)的(de)使用壽命(ming)與它被放電(dian)(dian)(dian)(dian)(dian)的(de)深度密切(qie)相(xiang)關(guan)。UPS電(dian)(dian)(dian)(dian)(dian)源所帶的(de)負載越輕(qing)，市電(dian)(dian)(dian)(dian)(dian)供(gong)電(dian)(dian)(dian)(dian)(dian)中斷時，蓄電(dian)(dian)(dian)(dian)(dian)他(ta)的(de)可(ke)供(gong)使用容量與其額定容量的(de)比值越大，在此情況下(xia)，當UPS電(dian)(dian)(dian)(dian)(dian)源因(yin)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)壓過低(di)而自動關(guan)機(ji)時電(dian)(dian)(dian)(dian)(dian)池被放電(dian)(dian)(dian)(dian)(dian)的(de)深度就比較深。

　　實際過程如何減少電(dian)(dian)池(chi)被深度(du)放電(dian)(dian)的事情發生呢？方法(fa)很簡單：當UPS電(dian)(dian)源處(chu)于市電(dian)(dian)供電(dian)(dian)中斷(duan)，改由(you)蓄電(dian)(dian)池(chi)向(xiang)逆變(bian)器供電(dian)(dian)狀態時，絕大多數(shu)UPS電(dian)(dian)源都會以間隙4s左右響一(yi)次的周期性報警(jing)聲，通(tong)知用(yong)戶現(xian)在是(shi)由(you)電(dian)(dian)池(chi)提供能量。當聽到報警(jing)聲變(bian)急(ji)促時，就說(shuo)明電(dian)(dian)源已處(chu)于深度(du)放電(dian)(dian)，應立即進行應急(ji)處(chu)理，關閉UPS電(dian)(dian)源。不(bu)(bu)是(shi)迫不(bu)(bu)得以，一(yi)般(ban)不(bu)(bu)要讓UPS電(dian)(dian)源一(yi)直(zhi)工(gong)作(zuo)到因(yin)電(dian)(dian)池(chi)電(dian)(dian)壓過低(di)而(er)自動關機才(cai)結束。

利用供電高峰充電

　　UPS電(dian)(dian)(dian)(dian)(dian)源用(yong)(yong)的(de)免維護密封電(dian)(dian)(dian)(dian)(dian)池(chi)不能用(yong)(yong)可控硅式的(de)“快速充(chong)電(dian)(dian)(dian)(dian)(dian)器”進行充(chong)電(dian)(dian)(dian)(dian)(dian)。這(zhe)是因為這(zhe)種充(chong)電(dian)(dian)(dian)(dian)(dian)器會(hui)(hui)造成蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)同時(shi)(shi)處于既“瞬時(shi)(shi)過(guo)(guo)(guo)(guo)流充(chong)電(dian)(dian)(dian)(dian)(dian)”又“瞬時(shi)(shi)過(guo)(guo)(guo)(guo)壓充(chong)電(dian)(dian)(dian)(dian)(dian)的(de)惡劣充(chong)電(dian)(dian)(dian)(dian)(dian)狀(zhuang)態(tai)。這(zhe)種狀(zhuang)態(tai)會(hui)(hui)使(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)可供使(shi)用(yong)(yong)容量大大下降，嚴(yan)重時(shi)(shi)會(hui)(hui)使(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)報廢(fei)。在采(cai)用(yong)(yong)恒壓截(jie)止型(xing)充(chong)電(dian)(dian)(dian)(dian)(dian)回路的(de)UPS電(dian)(dian)(dian)(dian)(dian)源時(shi)(shi)，注意不要將電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓過(guo)(guo)(guo)(guo)低保護工作點調(diao)得(de)過(guo)(guo)(guo)(guo)低，否則(ze)，在它充(chong)電(dian)(dian)(dian)(dian)(dian)初期容易(yi)產生(sheng)過(guo)(guo)(guo)(guo)流充(chong)電(dian)(dian)(dian)(dian)(dian)。

　　當然，最好選用既具有恒流，又有恒壓(ya)的充(chong)電器對(dui)其(qi)進(jin)行充(chong)電。
