我們平(ping)時(shi)給(gei)充(chong)電(dian)機(ji)充(chong)電(dian)，當蓄(xu)電(dian)池(chi)(chi)充(chong)滿(man)電(dian)后我們就直接把充(chong)電(dian)機(ji)線拔掉，其實這(zhe)樣的(de)(de)作法是完全錯誤的(de)(de)。充(chong)電(dian)工(gong)作完成后，需要給(gei)充(chong)電(dian)機(ji)堵(du)截充(chong)電(dian)電(dian)流，否(fou)則蓄(xu)電(dian)池(chi)(chi)將(jiang)出現大量出氣、失水和溫(wen)升(sheng)等過充(chong)的(de)(de)反應，這(zhe)將(jiang)危及到蓄(xu)電(dian)池(chi)(chi)的(de)(de)使用(yong)壽(shou)命。因此，隨時(shi)監測蓄(xu)電(dian)池(chi)(chi)的(de)(de)充(chong)電(dian)情況是非常有必要的(de)(de)，確保(bao)電(dian)池(chi)(chi)能(neng)夠(gou)把電(dian)充(chong)足并且又不過充(chong)電(dian)。主要的(de)(de)停充(chong)操控辦法有：

　　1、恒流(liu)充(chong)(chong)(chong)電(dian)(dian)定時(shi)控制法(fa)，電(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)充(chong)(chong)(chong)滿(man)時(shi)，我(wo)們(men)可(ke)以(yi)看電(dian)(dian)池的(de)容量大小，根據電(dian)(dian)流(liu)大小來(lai)確認。這(zhe)樣我(wo)們(men)就要先(xian)預定好充(chong)(chong)(chong)電(dian)(dian)的(de)時(shi)間，預定的(de)充(chong)(chong)(chong)電(dian)(dian)時(shi)間一到，充(chong)(chong)(chong)電(dian)(dian)機就發布(bu)信(xin)號停充(chong)(chong)(chong)。定時(shi)器可(ke)由時(shi)間繼電(dian)(dian)器充(chong)(chong)(chong)當(dang)，或(huo)許由單(dan)片機承當(dang)其功(gong)用。這(zhe)種辦(ban)法(fa)簡單(dan)，但充(chong)(chong)(chong)電(dian)(dian)時(shi)間不(bu)能(neng)依(yi)據電(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)前(qian)狀況(kuang)而(er)自動調整，因此實際(ji)充(chong)(chong)(chong)電(dian)(dian)時(shi)，可(ke)能(neng)會出現有時(shi)欠充(chong)(chong)(chong)、有時(shi)過充(chong)(chong)(chong)的(de)表象(xiang)；

　　2、電(dian)(dian)(dian)(dian)池(chi)(chi)溫(wen)(wen)度(du)(du)操，正常充電(dian)(dian)(dian)(dian)情況下(xia)，蓄電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)溫(wen)(wen)度(du)(du)變化并不明顯，當電(dian)(dian)(dian)(dian)池(chi)(chi)過充時，內部(bu)氣體壓力將(jiang)快速(su)增大，負極板上氧化反(fan)響使(shi)內部(bu)發熱，溫(wen)(wen)度(du)(du)快速(su)上升。因此，調查電(dian)(dian)(dian)(dian)池(chi)(chi)溫(wen)(wen)度(du)(du)的(de)改變，即(ji)可判別(bie)電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)否現已充溢。通常選用(yong)兩(liang)只熱敏電(dian)(dian)(dian)(dian)阻別(bie)離(li)檢測(ce)電(dian)(dian)(dian)(dian)池(chi)(chi)溫(wen)(wen)度(du)(du)和環境溫(wen)(wen)度(du)(du)，當兩(liang)者溫(wen)(wen)差(cha)到達一定值時，即(ji)宣布停充信號。因為熱敏電(dian)(dian)(dian)(dian)阻動(dong)態響應(ying)速(su)度(du)(du)較慢，故(gu)不能(neng)及時精確地檢測(ce)到電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)滿充狀(zhuang)況

　　3、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓負增量(liang)一般而言，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)充(chong)(chong)足(zu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)，其端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓將呈現(xian)降低(di)趨(qu)勢(shi)，據此(ci)可(ke)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓出(chu)現(xian)負增長的(de)(de)時間作為停充(chong)(chong)時間。與溫度(du)操控法(fa)比較，這(zhe)種辦(ban)法(fa)呼應(ying)速度(du)快(kuai)，此(ci)外，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)負增量(liang)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)絕對值無(wu)關，因(yin)此(ci)這(zhe)種停充(chong)(chong)操控辦(ban)法(fa)可(ke)適(shi)應(ying)具有不(bu)一樣單格電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)數的(de)(de)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)組充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。此(ci)辦(ban)法(fa)的(de)(de)缺陷是一般的(de)(de)檢測器(qi)靈敏度(du)和(he)可(ke)靠性(xing)不(bu)高(gao)，同時，當(dang)環(huan)境溫度(du)較高(gao)時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)足(zu)夠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)減(jian)小并(bing)不(bu)顯著(zhu)，因(yin)此(ci)難以操控；

　　4、使(shi)用(yong)(yong)極化(hua)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)操控通常情(qing)況下(xia)，蓄(xu)電(dian)(dian)(dian)(dian)(dian)池的(de)極化(hua)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)出(chu)現(xian)在電(dian)(dian)(dian)(dian)(dian)池剛好(hao)充滿后，選用(yong)(yong)有關專(zhuan)利技術來(lai)測量每個(ge)單格電(dian)(dian)(dian)(dian)(dian)池的(de)極化(hua)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，這樣就使(shi)每個(ge)電(dian)(dian)(dian)(dian)(dian)池都可充電(dian)(dian)(dian)(dian)(dian)到它(ta)自身所(suo)需求的(de)程度。研討表明，因為每個(ge)電(dian)(dian)(dian)(dian)(dian)池在幾何結構、化(hua)學(xue)(xue)性(xing)質及電(dian)(dian)(dian)(dian)(dian)學(xue)(xue)特(te)性(xing)等方面至少存在一些細微的(de)不同，那么依(yi)據(ju)每個(ge)單格電(dian)(dian)(dian)(dian)(dian)池的(de)特(te)性(xing)來(lai)斷定它(ta)所(suo)需求的(de)充電(dian)(dian)(dian)(dian)(dian)水平會比把蓄(xu)電(dian)(dian)(dian)(dian)(dian)池組作為一個(ge)整體來(lai)操控的(de)辦法更加適(shi)宜一些。
