我們平時(shi)給充(chong)電(dian)(dian)(dian)(dian)機(ji)充(chong)電(dian)(dian)(dian)(dian)，當蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池充(chong)滿電(dian)(dian)(dian)(dian)后我們就直接把充(chong)電(dian)(dian)(dian)(dian)機(ji)線(xian)拔(ba)掉，其實這(zhe)樣的(de)(de)作(zuo)法是完全(quan)錯誤的(de)(de)。充(chong)電(dian)(dian)(dian)(dian)工作(zuo)完成后，需(xu)要(yao)給充(chong)電(dian)(dian)(dian)(dian)機(ji)堵截充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，否則蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池將出現大量出氣(qi)、失(shi)水和溫升等過(guo)充(chong)的(de)(de)反(fan)應，這(zhe)將危及(ji)到(dao)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池的(de)(de)使用(yong)壽命。因此，隨時(shi)監測蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)池的(de)(de)充(chong)電(dian)(dian)(dian)(dian)情況是非常(chang)有(you)必要(yao)的(de)(de)，確保電(dian)(dian)(dian)(dian)池能夠把電(dian)(dian)(dian)(dian)充(chong)足并(bing)且又不過(guo)充(chong)電(dian)(dian)(dian)(dian)。主要(yao)的(de)(de)停充(chong)操控辦(ban)法有(you)：

　　1、恒流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)定時(shi)(shi)控制法，電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)充(chong)(chong)(chong)(chong)滿(man)時(shi)(shi)，我們(men)可以看電(dian)(dian)(dian)池(chi)的(de)容量大小，根據電(dian)(dian)(dian)流(liu)大小來(lai)確(que)認。這(zhe)樣我們(men)就(jiu)要先(xian)預(yu)定好充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)的(de)時(shi)(shi)間(jian)，預(yu)定的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)一(yi)到(dao)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)機就(jiu)發(fa)布信號停(ting)充(chong)(chong)(chong)(chong)。定時(shi)(shi)器(qi)可由(you)時(shi)(shi)間(jian)繼電(dian)(dian)(dian)器(qi)充(chong)(chong)(chong)(chong)當，或許由(you)單片機承當其功用(yong)。這(zhe)種(zhong)辦法簡(jian)單，但(dan)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)不能依據電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)前狀況而自動調整，因(yin)此(ci)實際充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)，可能會(hui)出現(xian)有時(shi)(shi)欠充(chong)(chong)(chong)(chong)、有時(shi)(shi)過充(chong)(chong)(chong)(chong)的(de)表象；

　　2、電池(chi)(chi)溫(wen)度(du)(du)(du)(du)操，正常(chang)充(chong)電情況下，蓄電池(chi)(chi)的(de)溫(wen)度(du)(du)(du)(du)變化并不明顯(xian)，當電池(chi)(chi)過(guo)充(chong)時，內部氣(qi)體(ti)壓力將快速(su)(su)增大，負極(ji)板上氧化反響使(shi)內部發熱(re)，溫(wen)度(du)(du)(du)(du)快速(su)(su)上升。因此，調(diao)查電池(chi)(chi)溫(wen)度(du)(du)(du)(du)的(de)改變，即可判(pan)別電池(chi)(chi)是(shi)否現(xian)已充(chong)溢。通(tong)常(chang)選用兩只熱(re)敏(min)電阻(zu)別離檢測電池(chi)(chi)溫(wen)度(du)(du)(du)(du)和環境溫(wen)度(du)(du)(du)(du)，當兩者溫(wen)差到達(da)一定值時，即宣布停充(chong)信(xin)號。因為熱(re)敏(min)電阻(zu)動態響應速(su)(su)度(du)(du)(du)(du)較慢，故不能及時精確地檢測到電池(chi)(chi)的(de)滿充(chong)狀況

　　3、電(dian)(dian)(dian)(dian)池(chi)端(duan)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)負(fu)增(zeng)量(liang)一般而言，當電(dian)(dian)(dian)(dian)池(chi)充(chong)足(zu)電(dian)(dian)(dian)(dian)后(hou)，其(qi)端(duan)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)將(jiang)呈(cheng)現(xian)降低(di)趨勢(shi)，據(ju)此(ci)(ci)(ci)可(ke)將(jiang)電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)出現(xian)負(fu)增(zeng)長的(de)(de)時(shi)(shi)間作(zuo)為(wei)停(ting)充(chong)時(shi)(shi)間。與溫度操控(kong)法(fa)(fa)(fa)比較(jiao)，這種(zhong)(zhong)辦(ban)(ban)法(fa)(fa)(fa)呼應速度快，此(ci)(ci)(ci)外，電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)負(fu)增(zeng)量(liang)與電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)絕對值(zhi)無關(guan)，因(yin)此(ci)(ci)(ci)這種(zhong)(zhong)停(ting)充(chong)操控(kong)辦(ban)(ban)法(fa)(fa)(fa)可(ke)適應具有(you)不(bu)一樣單格電(dian)(dian)(dian)(dian)池(chi)數的(de)(de)蓄電(dian)(dian)(dian)(dian)池(chi)組充(chong)電(dian)(dian)(dian)(dian)。此(ci)(ci)(ci)辦(ban)(ban)法(fa)(fa)(fa)的(de)(de)缺陷(xian)是一般的(de)(de)檢測(ce)器靈敏度和可(ke)靠(kao)性不(bu)高，同時(shi)(shi)，當環境溫度較(jiao)高時(shi)(shi)，電(dian)(dian)(dian)(dian)池(chi)足(zu)夠(gou)電(dian)(dian)(dian)(dian)后(hou)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)減小并不(bu)顯著，因(yin)此(ci)(ci)(ci)難以操控(kong)；

　　4、使(shi)(shi)用(yong)極(ji)化(hua)電(dian)(dian)(dian)壓(ya)(ya)操控通(tong)常情況下，蓄電(dian)(dian)(dian)池(chi)(chi)的(de)(de)極(ji)化(hua)電(dian)(dian)(dian)壓(ya)(ya)出(chu)現(xian)在(zai)電(dian)(dian)(dian)池(chi)(chi)剛好充滿(man)后，選用(yong)有關專利技(ji)術來(lai)測(ce)量每(mei)個(ge)單格電(dian)(dian)(dian)池(chi)(chi)的(de)(de)極(ji)化(hua)電(dian)(dian)(dian)壓(ya)(ya)，這(zhe)樣(yang)就使(shi)(shi)每(mei)個(ge)電(dian)(dian)(dian)池(chi)(chi)都可充電(dian)(dian)(dian)到它自身所(suo)(suo)需求的(de)(de)程度。研討表明，因為每(mei)個(ge)電(dian)(dian)(dian)池(chi)(chi)在(zai)幾何(he)結構、化(hua)學性質及電(dian)(dian)(dian)學特性等方(fang)面至少(shao)存在(zai)一(yi)些(xie)細微的(de)(de)不(bu)同，那么依據每(mei)個(ge)單格電(dian)(dian)(dian)池(chi)(chi)的(de)(de)特性來(lai)斷(duan)定它所(suo)(suo)需求的(de)(de)充電(dian)(dian)(dian)水平(ping)會比把蓄電(dian)(dian)(dian)池(chi)(chi)組作為一(yi)個(ge)整體來(lai)操控的(de)(de)辦法更加適宜一(yi)些(xie)。
