　　因此(ci)，將(jiang)導致(zhi)(zhi)電(dian)(dian)池(chi)的(de)熱失控和過充(chong)(chong)損壞。當充(chong)(chong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)比要求電(dian)(dian)壓(ya)(ya)低(di)100mv時(shi)，又將(jiang)使(shi)電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)不(bu)(bu)足，也(ye)會導致(zhi)(zhi)電(dian)(dian)池(chi)損壞。另外鉛(qian)酸(suan)(suan)(suan)蓄(xu)電(dian)(dian)池(chi)的(de)容量(liang)也(ye)和溫度有關，大約是(shi)溫度每降(jiang)低(di)1℃，容量(liang)將(jiang)下降(jiang)1%，所以(yi)廠家(jia)要求鉛(qian)酸(suan)(suan)(suan)蓄(xu)電(dian)(dian)池(chi)的(de)使(shi)用(yong)者在(zai)夏天(tian)電(dian)(dian)池(chi)放出額定(ding)容量(liang)的(de)50%后，冬(dong)天(tian)放出25%后就應及(ji)時(shi)充(chong)(chong)電(dian)(dian)。顯然，日常使(shi)用(yong)中(zhong)(zhong)的(de)鉛(qian)酸(suan)(suan)(suan)蓄(xu)電(dian)(dian)池(chi)不(bu)(bu)可能長期(qi)處在(zai)25℃的(de)環(huan)境(jing)中(zhong)(zhong)，一日中(zhong)(zhong)尚有早、中(zhong)(zhong)、晚的(de)溫差變化，更何況一年中(zhong)(zhong)還有春(chun)、夏、秋、冬(dong)四季(ji)更大的(de)溫差，因此(ci)目前市面上普遍使(shi)用(yong)的(de)各種晶閘管整流型、變壓(ya)(ya)器降(jiang)壓(ya)(ya)整流型、以(yi)及(ji)一?。縱觀過去所采用(yong)的(de)這(zhe)些對鉛(qian)酸(suan)(suan)(suan)蓄(xu)電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)的(de)方法(fa)，以(yi)及(ji)根據這(zhe)些方法(fa)的(de)鉛(qian)酸(suan)(suan)(suan)蓄(xu)電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)器，我(wo)們不(bu)(bu)難看出，其(qi)是(shi)不(bu)(bu)夠完善的(de)，用(yong)這(zhe)些產品給鉛(qian)酸(suan)(suan)(suan)蓄(xu)電(dian)(dian)池(chi)。

　　一般電池(chi)(chi)生產(chan)廠家要求(qiu)的(de)(de)環(huan)(huan)境(jing)溫(wen)度是(shi)在20℃-25℃之間。雖然溫(wen)度的(de)(de)升高對電池(chi)(chi)放(fang)電能(neng)力有(you)所，但付出(chu)的(de)(de)代(dai)價卻(que)是(shi)電池(chi)(chi)的(de)(de)壽命(ming)大大縮(suo)短。據試驗測定，環(huan)(huan)境(jing)溫(wen)度一旦(dan)超過25℃，每升高10℃，電池(chi)(chi)的(de)(de)壽命(ming)就要縮(suo)短一半。目前UPS所用的(de)(de)蓄(xu)電池(chi)(chi)一般都是(shi)免的(de)(de)密封鉛酸蓄(xu)電池(chi)(chi)，設計壽命(ming)普(pu)遍是(shi)5年，這(zhe)在電池(chi)(chi)生產(chan)廠家要求(qiu)的(de)(de)環(huan)(huan)境(jing)下才能(neng)達到。

　　溫度升高(gao)和電(dian)(dian)(dian)流的(de)(de)增(zeng)大互相促進,使電(dian)(dian)(dian)池(chi)內部溫度可以(yi)高(gao)達120℃以(yi)上(shang),軟(ruan)化ABS外(wai)(wai)殼(ke)(ABS軟(ruan)化點90℃左右),從(cong)而發生(sheng)電(dian)(dian)(dian)池(chi)的(de)(de),漏(lou)液(ye)(ye),起火。所以(yi)說(shuo)浮(fu)充(chong)本質(zhi)上(shang)也是一種過(guo)(guo)充(chong)電(dian)(dian)(dian)。如(ru)果電(dian)(dian)(dian)池(chi)出現過(guo)(guo)充(chong)電(dian)(dian)(dian),電(dian)(dian)(dian)池(chi)內部電(dian)(dian)(dian)解水(shui)的(de)(de)速率將會(hui)(hui)加快,這些氣體(ti)來不及(ji)被吸收,會(hui)(hui)不斷積累,當(dang)(dang)電(dian)(dian)(dian)池(chi)內部壓力(li)超過(guo)(guo)開閥壓后排出氫(qing)氧(yang)混(hun)合(he)易燃易爆氣體(ti),如(ru)果站點密封(feng)(feng)較好,在(zai)(zai)(zai)外(wai)(wai)部有(you)火花時即(ji)容易引(yin)燃引(yin)爆。蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)漏(lou)液(ye)(ye)鉛酸蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)漏(lou)液(ye)(ye)指的(de)(de)是電(dian)(dian)(dian)池(chi)在(zai)(zai)(zai)使用過(guo)(guo)程中(zhong),電(dian)(dian)(dian)圖2連(lian)接(jie)(jie)松(song)動引(yin)起的(de)(de)火災池(chi)表面(mian)有(you)電(dian)(dian)(dian)解液(ye)(ye)滲出。蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)漏(lou)酸的(de)(de)原因一般可分為三(san)類:①生(sheng)產過(guo)(guo)程中(zhong)的(de)(de)結構性(xing)密封(feng)(feng)損傷,如(ru)極柱和外(wai)(wai)殼(ke)焊接(jie)(jie)或(huo)(huo)粘接(jie)(jie)面(mian)存(cun)在(zai)(zai)(zai)未(wei)能及(ji)時發現的(de)(de)缺陷。在(zai)(zai)(zai)使用中(zhong)產生(sheng)漏(lou)液(ye)(ye)現象;②運輸或(huo)(huo)者安裝(zhuang)過(guo)(guo)程中(zhong)的(de)(de)不當(dang)(dang)操作(zuo),引(yin)起的(de)(de)蓄(xu)(xu)(xu)電(dian)(dian)(dian)池(chi)外(wai)(wai)殼(ke)顯性(xing)或(huo)(huo)者隱形的(de)(de)損壞,并而未(wei)及(ji)時排除;③充(chong)電(dian)(dian)(dian)設置(zhi)不合(he)理,使電(dian)(dian)(dian)池(chi)組長期過(guo)(guo)充(chong)電(dian)(dian)(dian)導板生(sheng)長,外(wai)(wai)殼(ke)破壞,導致的(de)(de)。
