我(wo)們平時給充(chong)電(dian)機充(chong)電(dian)，當(dang)蓄(xu)電(dian)池(chi)充(chong)滿電(dian)后我(wo)們就直接把(ba)(ba)充(chong)電(dian)機線拔(ba)掉(diao)，其實這(zhe)樣的作(zuo)法是完(wan)全錯誤的。充(chong)電(dian)工作(zuo)完(wan)成后，需要(yao)給充(chong)電(dian)機堵截充(chong)電(dian)電(dian)流，否則蓄(xu)電(dian)池(chi)將(jiang)出現大量(liang)出氣、失(shi)水(shui)和溫升等過充(chong)的反應，這(zhe)將(jiang)危及到蓄(xu)電(dian)池(chi)的使用壽命。因(yin)此，隨時監測蓄(xu)電(dian)池(chi)的充(chong)電(dian)情況是非常有必要(yao)的，確保電(dian)池(chi)能夠(gou)把(ba)(ba)電(dian)充(chong)足并且又不過充(chong)電(dian)。主要(yao)的停充(chong)操控辦法有：

　　1、恒流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)定(ding)(ding)時(shi)控制法，電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)充(chong)(chong)(chong)滿時(shi)，我們可(ke)以看(kan)電(dian)(dian)(dian)(dian)池的容量大小(xiao)，根據電(dian)(dian)(dian)(dian)流大小(xiao)來確(que)認。這(zhe)樣(yang)我們就要先預定(ding)(ding)好充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的時(shi)間(jian)，預定(ding)(ding)的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)一(yi)到(dao)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機就發布信號停充(chong)(chong)(chong)。定(ding)(ding)時(shi)器可(ke)由(you)時(shi)間(jian)繼電(dian)(dian)(dian)(dian)器充(chong)(chong)(chong)當，或(huo)許(xu)由(you)單(dan)片(pian)機承當其(qi)功用(yong)。這(zhe)種辦法簡單(dan)，但充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)不(bu)能依據電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)前狀(zhuang)況而自(zi)動調(diao)整，因此(ci)實際充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)，可(ke)能會(hui)出(chu)現有時(shi)欠充(chong)(chong)(chong)、有時(shi)過充(chong)(chong)(chong)的表象；

　　2、電(dian)池(chi)(chi)(chi)溫度(du)(du)操(cao)，正常充(chong)電(dian)情況(kuang)下，蓄電(dian)池(chi)(chi)(chi)的溫度(du)(du)變化并不明(ming)顯，當電(dian)池(chi)(chi)(chi)過充(chong)時(shi)(shi)，內(nei)部(bu)氣體壓力(li)將快速增大，負極板(ban)上氧化反響使(shi)內(nei)部(bu)發熱(re)，溫度(du)(du)快速上升。因此，調查(cha)電(dian)池(chi)(chi)(chi)溫度(du)(du)的改變，即可判別電(dian)池(chi)(chi)(chi)是否(fou)現(xian)已(yi)充(chong)溢。通常選用(yong)兩(liang)只熱(re)敏(min)電(dian)阻(zu)(zu)別離檢測(ce)電(dian)池(chi)(chi)(chi)溫度(du)(du)和環境溫度(du)(du)，當兩(liang)者溫差到達一(yi)定(ding)值時(shi)(shi)，即宣布停(ting)充(chong)信(xin)號(hao)。因為熱(re)敏(min)電(dian)阻(zu)(zu)動態響應速度(du)(du)較(jiao)慢(man)，故不能及(ji)時(shi)(shi)精確地檢測(ce)到電(dian)池(chi)(chi)(chi)的滿充(chong)狀況(kuang)

　　3、電(dian)(dian)(dian)池(chi)端(duan)電(dian)(dian)(dian)壓(ya)負(fu)增(zeng)量(liang)一(yi)(yi)(yi)般(ban)而言，當(dang)電(dian)(dian)(dian)池(chi)充足電(dian)(dian)(dian)后，其端(duan)電(dian)(dian)(dian)壓(ya)將呈現降低趨勢，據此(ci)可(ke)將電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)出現負(fu)增(zeng)長(chang)的(de)(de)時(shi)間作為(wei)停充時(shi)間。與溫度操控(kong)法比較，這種辦(ban)法呼應速度快(kuai)，此(ci)外，電(dian)(dian)(dian)壓(ya)的(de)(de)負(fu)增(zeng)量(liang)與電(dian)(dian)(dian)壓(ya)的(de)(de)絕對(dui)值無(wu)關(guan)，因此(ci)這種停充操控(kong)辦(ban)法可(ke)適應具有不一(yi)(yi)(yi)樣單格(ge)電(dian)(dian)(dian)池(chi)數(shu)的(de)(de)蓄電(dian)(dian)(dian)池(chi)組充電(dian)(dian)(dian)。此(ci)辦(ban)法的(de)(de)缺陷是一(yi)(yi)(yi)般(ban)的(de)(de)檢測器靈敏度和可(ke)靠性不高，同(tong)時(shi)，當(dang)環境溫度較高時(shi)，電(dian)(dian)(dian)池(chi)足夠(gou)電(dian)(dian)(dian)后電(dian)(dian)(dian)壓(ya)的(de)(de)減小并不顯著(zhu)，因此(ci)難(nan)以操控(kong)；

　　4、使用極化(hua)電壓操控通(tong)常情(qing)況下(xia)，蓄電池(chi)(chi)的(de)(de)極化(hua)電壓出現在電池(chi)(chi)剛好充滿后，選用有關專利技術來(lai)測量(liang)每個(ge)單(dan)格(ge)電池(chi)(chi)的(de)(de)極化(hua)電壓，這樣就使每個(ge)電池(chi)(chi)都(dou)可充電到(dao)它自身(shen)所(suo)需求的(de)(de)程度。研討表明，因為每個(ge)電池(chi)(chi)在幾何結構、化(hua)學性(xing)質(zhi)及電學特(te)性(xing)等(deng)方面至少存在一(yi)些(xie)細微的(de)(de)不(bu)同，那么依據每個(ge)單(dan)格(ge)電池(chi)(chi)的(de)(de)特(te)性(xing)來(lai)斷定它所(suo)需求的(de)(de)充電水平(ping)會(hui)比把(ba)蓄電池(chi)(chi)組(zu)作(zuo)為一(yi)個(ge)整體來(lai)操控的(de)(de)辦法更(geng)加適宜(yi)一(yi)些(xie)。
