我們平時給(gei)充(chong)(chong)電(dian)(dian)(dian)機(ji)(ji)充(chong)(chong)電(dian)(dian)(dian)，當蓄電(dian)(dian)(dian)池(chi)充(chong)(chong)滿電(dian)(dian)(dian)后我們就直接把充(chong)(chong)電(dian)(dian)(dian)機(ji)(ji)線拔掉，其實這(zhe)樣的(de)(de)作法是(shi)完(wan)(wan)全(quan)錯誤的(de)(de)。充(chong)(chong)電(dian)(dian)(dian)工作完(wan)(wan)成后，需(xu)要(yao)給(gei)充(chong)(chong)電(dian)(dian)(dian)機(ji)(ji)堵截充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流，否則(ze)蓄電(dian)(dian)(dian)池(chi)將出現(xian)大(da)量出氣、失水和溫升(sheng)等過(guo)充(chong)(chong)的(de)(de)反應，這(zhe)將危及到(dao)蓄電(dian)(dian)(dian)池(chi)的(de)(de)使用壽命。因此(ci)，隨時監測蓄電(dian)(dian)(dian)池(chi)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)情況是(shi)非常(chang)有(you)必要(yao)的(de)(de)，確(que)保電(dian)(dian)(dian)池(chi)能夠(gou)把電(dian)(dian)(dian)充(chong)(chong)足(zu)并且又不過(guo)充(chong)(chong)電(dian)(dian)(dian)。主要(yao)的(de)(de)停(ting)充(chong)(chong)操控辦法有(you)：

　　1、恒流充(chong)電(dian)(dian)(dian)定(ding)(ding)時(shi)(shi)(shi)(shi)(shi)控制法(fa)，電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)充(chong)滿時(shi)(shi)(shi)(shi)(shi)，我(wo)們可以看(kan)電(dian)(dian)(dian)池的(de)容(rong)量大小(xiao)(xiao)，根據電(dian)(dian)(dian)流大小(xiao)(xiao)來確(que)認。這(zhe)樣我(wo)們就(jiu)要先(xian)預定(ding)(ding)好充(chong)電(dian)(dian)(dian)的(de)時(shi)(shi)(shi)(shi)(shi)間(jian)，預定(ding)(ding)的(de)充(chong)電(dian)(dian)(dian)時(shi)(shi)(shi)(shi)(shi)間(jian)一到，充(chong)電(dian)(dian)(dian)機(ji)就(jiu)發布信號停充(chong)。定(ding)(ding)時(shi)(shi)(shi)(shi)(shi)器可由(you)時(shi)(shi)(shi)(shi)(shi)間(jian)繼電(dian)(dian)(dian)器充(chong)當，或許(xu)由(you)單(dan)片機(ji)承當其功(gong)用(yong)。這(zhe)種辦法(fa)簡單(dan)，但充(chong)電(dian)(dian)(dian)時(shi)(shi)(shi)(shi)(shi)間(jian)不能依據電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)前(qian)狀況而(er)自(zi)動調(diao)整，因此實(shi)際充(chong)電(dian)(dian)(dian)時(shi)(shi)(shi)(shi)(shi)，可能會出(chu)現有(you)時(shi)(shi)(shi)(shi)(shi)欠充(chong)、有(you)時(shi)(shi)(shi)(shi)(shi)過充(chong)的(de)表象；

　　2、電(dian)池(chi)溫度操，正常(chang)充(chong)(chong)電(dian)情況下，蓄電(dian)池(chi)的(de)溫度變化并(bing)不(bu)明顯，當(dang)電(dian)池(chi)過充(chong)(chong)時，內部(bu)氣(qi)體壓力將快速(su)增大(da)，負極板(ban)上(shang)氧(yang)化反響使(shi)內部(bu)發熱(re)，溫度快速(su)上(shang)升。因此，調(diao)查電(dian)池(chi)溫度的(de)改變，即可判別電(dian)池(chi)是否現(xian)已充(chong)(chong)溢。通常(chang)選用兩只熱(re)敏電(dian)阻(zu)(zu)別離檢測(ce)電(dian)池(chi)溫度和環(huan)境(jing)溫度，當(dang)兩者溫差到(dao)達一定值(zhi)時，即宣布停充(chong)(chong)信號。因為熱(re)敏電(dian)阻(zu)(zu)動(dong)態(tai)響應(ying)速(su)度較慢，故不(bu)能及時精確(que)地檢測(ce)到(dao)電(dian)池(chi)的(de)滿充(chong)(chong)狀(zhuang)況

　　3、電(dian)(dian)(dian)(dian)池端電(dian)(dian)(dian)(dian)壓負(fu)增(zeng)量一般而言(yan)，當(dang)電(dian)(dian)(dian)(dian)池充足電(dian)(dian)(dian)(dian)后(hou)，其端電(dian)(dian)(dian)(dian)壓將呈(cheng)現降低趨勢，據此(ci)可將電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓出現負(fu)增(zeng)長(chang)的(de)時間(jian)作(zuo)為(wei)停(ting)充時間(jian)。與(yu)溫度操控法(fa)比(bi)較，這種辦(ban)法(fa)呼應速度快，此(ci)外，電(dian)(dian)(dian)(dian)壓的(de)負(fu)增(zeng)量與(yu)電(dian)(dian)(dian)(dian)壓的(de)絕對值(zhi)無(wu)關，因此(ci)這種停(ting)充操控辦(ban)法(fa)可適應具有(you)不一樣單格電(dian)(dian)(dian)(dian)池數(shu)的(de)蓄電(dian)(dian)(dian)(dian)池組充電(dian)(dian)(dian)(dian)。此(ci)辦(ban)法(fa)的(de)缺陷是一般的(de)檢測器靈(ling)敏度和可靠性不高，同時，當(dang)環境溫度較高時，電(dian)(dian)(dian)(dian)池足夠電(dian)(dian)(dian)(dian)后(hou)電(dian)(dian)(dian)(dian)壓的(de)減小并不顯(xian)著，因此(ci)難以操控；

　　4、使用(yong)極(ji)化(hua)電(dian)壓(ya)操控通常情況下，蓄(xu)電(dian)池(chi)(chi)的極(ji)化(hua)電(dian)壓(ya)出現在電(dian)池(chi)(chi)剛好充(chong)滿后，選用(yong)有關專利技術來測量(liang)每(mei)(mei)個(ge)單(dan)(dan)格電(dian)池(chi)(chi)的極(ji)化(hua)電(dian)壓(ya)，這樣就使每(mei)(mei)個(ge)電(dian)池(chi)(chi)都(dou)可充(chong)電(dian)到它自(zi)身(shen)所需求的程(cheng)度。研討表(biao)明，因為每(mei)(mei)個(ge)電(dian)池(chi)(chi)在幾何(he)結構、化(hua)學性(xing)質及電(dian)學特性(xing)等方面至少存(cun)在一些細微的不同，那么依(yi)據每(mei)(mei)個(ge)單(dan)(dan)格電(dian)池(chi)(chi)的特性(xing)來斷定它所需求的充(chong)電(dian)水平會比把(ba)蓄(xu)電(dian)池(chi)(chi)組(zu)作為一個(ge)整(zheng)體來操控的辦法更加適宜一些。
