蓄電池發熱(re)程(cheng)度不(bu)(bu)同(tong)對蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)損壞就不(bu)(bu)同(tong)。蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)只要工(gong)作就會發熱(re)，那是(shi)因(yin)為工(gong)作放電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)(guo)程(cheng)中，蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)內部化(hua)學物(wu)質(zhi)活(huo)躍(yue)發生反應釋放能量的原(yuan)因(yin)。但是(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)(dian)(dian)(dian)過(guo)(guo)快，有可能是(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量小，放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流長時(shi)間(jian)超(chao)過(guo)(guo)0.5C。這里著重強調：短途行駛后(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)雖然消耗(hao)(hao)一(yi)定的電(dian)(dian)(dian)(dian)(dian)(dian)量，但靜止以后(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)有一(yi)個(ge)恢復過(guo)(guo)程(cheng)，極板的電(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學過(guo)(guo)程(cheng)仍然繼(ji)續進行，因(yin)此電(dian)(dian)(dian)(dian)(dian)(dian)壓會有所回升，但并不(bu)(bu)意味著容量回升;相反，長途行駛時(shi)路途不(bu)(bu)停車，極板的電(dian)(dian)(dian)(dian)(dian)(dian)化(hua)作用(yong)與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)能的消耗(hao)(hao)同(tong)時(shi)進行，這會有三種情況出現：

1、當電(dian)(dian)機額定電(dian)(dian)壓值低，蓄(xu)電(dian)(dian)池容量較小，工作電(dian)(dian)流偏大(da)，電(dian)(dian)壓會(hui)急劇降低，容量也很(hen)快(kuai)消耗殆盡，對電(dian)(dian)池最為不利。

2、蓄電(dian)(dian)(dian)池的電(dian)(dian)(dian)化學反應(ying)速(su)度僅能夠維持行車，電(dian)(dian)(dian)池沒有(you)恢復和喘息的機會(hui)，經(jing)常做整(zheng)循環充放電(dian)(dian)(dian)，稍不注意便(bian)會(hui)超消耗。遇到迎風上(shang)坡，耗電(dian)(dian)(dian)甚大(da)，迫使電(dian)(dian)(dian)池極板急(ji)劇反應(ying)，電(dian)(dian)(dian)池外殼(ke)的熱度較高，會(hui)使電(dian)(dian)(dian)池受到損傷，縮(suo)短壽命，說明容量(liang)也不富余。

3、比較(jiao)理想(xiang)的(de)是電(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)化學反(fan)應速度能從(cong)容地供給足夠的(de)電(dian)(dian)(dian)(dian)能。電(dian)(dian)(dian)(dian)池的(de)外殼沒有(you)異常熱度，說明電(dian)(dian)(dian)(dian)池容量是富余的(de)。

三種情況只(zhi)有最(zui)后一種做(zuo)長(chang)途行車是理想的。應(ying)當說明一點(dian)，電(dian)(dian)池(chi)外(wai)殼明顯(xian)發熱(re)(re)，內部電(dian)(dian)池(chi)本身的熱(re)(re)度就更高了。

蓄電(dian)(dian)池(chi)(chi)在充電(dian)(dian)過(guo)程中，電(dian)(dian)能(neng)一部分(fen)轉變為(wei)化(hua)學(xue)能(neng)，還用(yong)一部分(fen)轉變為(wei)熱能(neng)和其他能(neng)量(liang)。充電(dian)(dian)電(dian)(dian)池(chi)(chi)發熱屬于正常現象，但是溫度(du)較高時就應及時檢查充電(dian)(dian)電(dian)(dian)流是否過(guo)大或者電(dian)(dian)池(chi)(chi)內部發生短路(lu)等，

發(fa)(fa)熱量與電(dian)解液量關系較小,如(ru)是密封電(dian)池電(dian)解液量較少(shao)時內(nei)阻增(zeng)大,也會引起電(dian)池升溫并且充(chong)電(dian)時端電(dian)壓(ya)很高。電(dian)池衰老、電(dian)解液干涸、內(nei)部有短路等同樣也會造成發(fa)(fa)熱。充(chong)電(dian)器不能在充(chong)電(dian)后(hou)期恒壓(ya)，以至造成電(dian)池電(dian)壓(ya)超過允許值，溫度會升高，嚴重(zhong)的會鼓(gu)脹，壽命(ming)終結。

使(shi)用中(zhong)，盡量(liang)不橫放或倒放，防止電池內部(bu)一時大量(liang)產氣不能(neng)順利從放氣閥排出(chu)，尤(you)其(qi)充(chong)電時更是(shi)如此(ci)，否則可(ke)能(neng)引(yin)起外殼爆裂。
