鉛(qian)(qian)酸蓄電(dian)(dian)池(chi)充(chong)電(dian)(dian)時發熱燙(tang)手是怎么回事(shi)？在充(chong)電(dian)(dian)時，電(dian)(dian)池(chi)內(nei)部的硫酸鉛(qian)(qian)變(bian)(bian)為鉛(qian)(qian)或氧化鉛(qian)(qian)，極板(ban)細孔(kong)內(nei)硫酸劇(ju)增(zeng)，濃度變(bian)(bian)大(da)(da)，同時內(nei)電(dian)(dian)阻增(zeng)大(da)(da)，極板(ban)電(dian)(dian)阻，電(dian)(dian)解(jie)液電(dian)(dian)阻，隔板(ban)電(dian)(dian)阻等都隨(sui)之(zhi)改變(bian)(bian)。較簡單(dan)的道理就是電(dian)(dian)阻大(da)(da)了導(dao)致發熱，正常現象。
鉛酸電(dian)(dian)(dian)池(chi)有2伏，4伏，6伏，8伏，12伏，24伏等系列，容(rong)量從(cong)200毫安(an)時到3000安(an)時。VRLA電(dian)(dian)(dian)池(chi)是基于AGM（吸液玻(bo)璃纖維板(ban)）技術和(he)鈣柵板(ban)的可充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)，具有優越(yue)的大電(dian)(dian)(dian)流放電(dian)(dian)(dian)特性(xing)和(he)超長的使用壽(shou)命(ming)。當VRLA蓄電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)將(jiang)達到頂點時，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流只被用來分(fen)解電(dian)(dian)(dian)解液中的水(shui)，此時，電(dian)(dian)(dian)池(chi)正極產生氧氣，負極產生氫氣，氣體會從(cong)蓄電(dian)(dian)(dian)池(chi)中溢出，造成電(dian)(dian)(dian)解液減少(shao)，需不定(ding)時加(jia)水(shui)。
蓄電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時發熱(re)溫(wen)度(du)(du)過(guo)(guo)高(gao)屬于正常現象，但(dan)是(shi)溫(wen)度(du)(du)不能(neng)超(chao)過(guo)(guo)40攝氏度(du)(du)，如(ru)果超(chao)過(guo)(guo)了應停(ting)止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，待溫(wen)度(du)(du)下降(jiang)后(hou)再進行充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)過(guo)(guo)程(cheng)中電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)會發熱(re)的(de)(de)(de)，不用(yong)(yong)大驚小怪，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)有內阻，充(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)有電(dian)(dian)(dian)(dian)(dian)流(liu)，做(zuo)的(de)(de)(de)功主(zhu)要以(yi)熱(re)量(liang)的(de)(de)(de)形式表現出來，一般的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)過(guo)(guo)程(cheng)中都是(shi)采用(yong)(yong)大電(dian)(dian)(dian)(dian)(dian)壓(ya)直(zhi)接夾(jia)在電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)兩端從而達到(dao)電(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)目的(de)(de)(de)，此過(guo)(guo)程(cheng)中電(dian)(dian)(dian)(dian)(dian)流(liu)不變，電(dian)(dian)(dian)(dian)(dian)壓(ya)就必須增大！同樣的(de)(de)(de)道理(li)用(yong)(yong)恒壓(ya)法也是(shi)一樣的(de)(de)(de)！所以(yi)當(dang)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)完成以(yi)后(hou)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)將高(gao)于電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)標注的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)！
蓄電(dian)池(chi)組充電(dian)發(fa)熱(re)有幾(ji)個原因(yin)：1.電(dian)流控制，2.單個蓄電(dian)池(chi)內部電(dian)阻(zu)大，3.充電(dian)室通風，4.整體蓄電(dian)池(chi)硫(liu)化(hua)。
充(chong)電(dian)(dian)后電(dian)(dian)池的(de)(de)內(nei)(nei)(nei)阻應(ying)該是減小的(de)(de)；你(ni)可以測量一下(xia)充(chong)滿電(dian)(dian)的(de)(de)電(dian)(dian)池的(de)(de)內(nei)(nei)(nei)阻，肯定比放電(dian)(dian)后的(de)(de)電(dian)(dian)池的(de)(de)內(nei)(nei)(nei)阻小很多的(de)(de)。
充(chong)(chong)電(dian)(dian)(dian)(dian)發(fa)熱，應(ying)該是電(dian)(dian)(dian)(dian)流偏大，由(you)于電(dian)(dian)(dian)(dian)池(chi)有一定的內阻(zu)，所以會(hui)生成(cheng)熱量(liang)，而這個熱量(liang)很(hen)難迅速散(san)發(fa)，因為電(dian)(dian)(dian)(dian)池(chi)一般是塑料外殼，因此電(dian)(dian)(dian)(dian)池(chi)的溫度(du)會(hui)越來越高。減小充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，電(dian)(dian)(dian)(dian)池(chi)發(fa)熱的程(cheng)度(du)會(hui)降低很(hen)多(duo)。
