我們平時(shi)給(gei)充(chong)(chong)(chong)電(dian)(dian)(dian)機(ji)(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)，當蓄(xu)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)滿電(dian)(dian)(dian)后我們就直接把(ba)(ba)充(chong)(chong)(chong)電(dian)(dian)(dian)機(ji)(ji)線拔掉，其實這(zhe)樣的作(zuo)法是完全錯誤(wu)的。充(chong)(chong)(chong)電(dian)(dian)(dian)工作(zuo)完成后，需要給(gei)充(chong)(chong)(chong)電(dian)(dian)(dian)機(ji)(ji)堵(du)截(jie)充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)，否則(ze)蓄(xu)電(dian)(dian)(dian)池(chi)將(jiang)出現大量出氣、失(shi)水和溫升等過充(chong)(chong)(chong)的反(fan)應，這(zhe)將(jiang)危及到蓄(xu)電(dian)(dian)(dian)池(chi)的使(shi)用(yong)壽命。因(yin)此，隨時(shi)監測蓄(xu)電(dian)(dian)(dian)池(chi)的充(chong)(chong)(chong)電(dian)(dian)(dian)情況是非常有(you)必要的，確保電(dian)(dian)(dian)池(chi)能夠把(ba)(ba)電(dian)(dian)(dian)充(chong)(chong)(chong)足并(bing)且又(you)不過充(chong)(chong)(chong)電(dian)(dian)(dian)。主要的停充(chong)(chong)(chong)操控辦法有(you)：

　　1、恒流充(chong)(chong)(chong)電(dian)定(ding)(ding)時(shi)(shi)控制法(fa)，電(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)充(chong)(chong)(chong)滿(man)時(shi)(shi)，我(wo)(wo)們(men)可(ke)以看電(dian)池(chi)(chi)的(de)(de)容量大小，根據(ju)電(dian)流大小來確認(ren)。這樣我(wo)(wo)們(men)就要先預(yu)定(ding)(ding)好充(chong)(chong)(chong)電(dian)的(de)(de)時(shi)(shi)間，預(yu)定(ding)(ding)的(de)(de)充(chong)(chong)(chong)電(dian)時(shi)(shi)間一到，充(chong)(chong)(chong)電(dian)機(ji)就發布信號停充(chong)(chong)(chong)。定(ding)(ding)時(shi)(shi)器可(ke)由(you)(you)時(shi)(shi)間繼電(dian)器充(chong)(chong)(chong)當(dang)，或許由(you)(you)單片機(ji)承(cheng)當(dang)其功用(yong)。這種辦(ban)法(fa)簡單，但充(chong)(chong)(chong)電(dian)時(shi)(shi)間不(bu)能依據(ju)電(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)前狀(zhuang)況而自動(dong)調整，因此實際充(chong)(chong)(chong)電(dian)時(shi)(shi)，可(ke)能會(hui)出現有時(shi)(shi)欠充(chong)(chong)(chong)、有時(shi)(shi)過充(chong)(chong)(chong)的(de)(de)表(biao)象；

　　2、電(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度(du)操(cao)，正(zheng)常充(chong)(chong)電(dian)(dian)(dian)情況(kuang)下，蓄電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)溫(wen)(wen)(wen)度(du)變化(hua)并不明(ming)顯，當電(dian)(dian)(dian)池(chi)(chi)(chi)過(guo)充(chong)(chong)時，內(nei)部氣體(ti)壓力將快速(su)增大，負(fu)極(ji)板上氧化(hua)反響(xiang)使內(nei)部發熱(re)(re)，溫(wen)(wen)(wen)度(du)快速(su)上升。因此，調查電(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度(du)的(de)改變，即可判別(bie)電(dian)(dian)(dian)池(chi)(chi)(chi)是否現已充(chong)(chong)溢(yi)。通(tong)常選(xuan)用(yong)兩只熱(re)(re)敏(min)電(dian)(dian)(dian)阻別(bie)離檢測電(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度(du)和(he)環境溫(wen)(wen)(wen)度(du)，當兩者溫(wen)(wen)(wen)差到達一(yi)定值時，即宣布停充(chong)(chong)信(xin)號。因為(wei)熱(re)(re)敏(min)電(dian)(dian)(dian)阻動態響(xiang)應速(su)度(du)較慢，故不能及時精確地檢測到電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)滿充(chong)(chong)狀況(kuang)

　　3、電(dian)(dian)(dian)池(chi)(chi)(chi)端(duan)電(dian)(dian)(dian)壓(ya)負(fu)增(zeng)(zeng)量一般(ban)而言，當電(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)足電(dian)(dian)(dian)后(hou)，其端(duan)電(dian)(dian)(dian)壓(ya)將呈現降低趨勢，據此可(ke)將電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓(ya)出(chu)現負(fu)增(zeng)(zeng)長的時間(jian)作為停(ting)充(chong)時間(jian)。與溫(wen)度(du)操(cao)控(kong)法比較，這種辦法呼應(ying)速度(du)快，此外(wai)，電(dian)(dian)(dian)壓(ya)的負(fu)增(zeng)(zeng)量與電(dian)(dian)(dian)壓(ya)的絕對值無關，因此這種停(ting)充(chong)操(cao)控(kong)辦法可(ke)適應(ying)具(ju)有不一樣單(dan)格電(dian)(dian)(dian)池(chi)(chi)(chi)數的蓄電(dian)(dian)(dian)池(chi)(chi)(chi)組充(chong)電(dian)(dian)(dian)。此辦法的缺陷是一般(ban)的檢測器(qi)靈敏度(du)和可(ke)靠性不高，同時，當環境溫(wen)度(du)較高時，電(dian)(dian)(dian)池(chi)(chi)(chi)足夠電(dian)(dian)(dian)后(hou)電(dian)(dian)(dian)壓(ya)的減小并不顯(xian)著，因此難(nan)以操(cao)控(kong)；

　　4、使用極(ji)化電(dian)(dian)壓(ya)(ya)(ya)操(cao)控(kong)通常情況下(xia)，蓄電(dian)(dian)池(chi)的(de)(de)(de)極(ji)化電(dian)(dian)壓(ya)(ya)(ya)出(chu)現(xian)在(zai)電(dian)(dian)池(chi)剛好充滿后，選用有關(guan)專利技術來(lai)測量(liang)每(mei)(mei)個(ge)單格(ge)電(dian)(dian)池(chi)的(de)(de)(de)極(ji)化電(dian)(dian)壓(ya)(ya)(ya)，這樣(yang)就使每(mei)(mei)個(ge)電(dian)(dian)池(chi)都可(ke)充電(dian)(dian)到它(ta)自身所(suo)需求的(de)(de)(de)程度。研(yan)討(tao)表明(ming)，因為每(mei)(mei)個(ge)電(dian)(dian)池(chi)在(zai)幾何(he)結構、化學(xue)性質及電(dian)(dian)學(xue)特性等方(fang)面至(zhi)少(shao)存在(zai)一(yi)(yi)些細微的(de)(de)(de)不同，那么依據每(mei)(mei)個(ge)單格(ge)電(dian)(dian)池(chi)的(de)(de)(de)特性來(lai)斷定它(ta)所(suo)需求的(de)(de)(de)充電(dian)(dian)水平會比把蓄電(dian)(dian)池(chi)組作為一(yi)(yi)個(ge)整(zheng)體(ti)來(lai)操(cao)控(kong)的(de)(de)(de)辦法更加適(shi)宜一(yi)(yi)些。
