當蓄(xu)電(dian)(dian)(dian)池(chi)(chi)充(chong)足(zu)電(dian)(dian)(dian)后(hou)，充(chong)電(dian)(dian)(dian)機(ji)必(bi)須適時地切斷充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流，否則蓄(xu)電(dian)(dian)(dian)池(chi)(chi)將出現大量出氣、失水和(he)溫升等過(guo)充(chong)反(fan)應，直接危及蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的使用壽命(ming)。因此，必(bi)須隨時監測蓄(xu)電(dian)(dian)(dian)池(chi)(chi)的充(chong)電(dian)(dian)(dian)狀(zhuang)況，保證電(dian)(dian)(dian)池(chi)(chi)充(chong)足(zu)電(dian)(dian)(dian)而又不過(guo)充(chong)電(dian)(dian)(dian)。主要(yao)的停(ting)充(chong)控制方法有：
（1）定時(shi)(shi)(shi)控制采用恒流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)法時(shi)(shi)(shi)，電(dian)(dian)(dian)(dian)池(chi)所需充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間可(ke)根(gen)據電(dian)(dian)(dian)(dian)池(chi)容(rong)量和充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)的(de)大小(xiao)很容(rong)易地(di)確(que)定，因此(ci)只(zhi)要預先設定好(hao)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間，一旦時(shi)(shi)(shi)間一到，定時(shi)(shi)(shi)器(qi)即可(ke)發出(chu)信號停充(chong)(chong)(chong)(chong)或(huo)降為(wei)涓流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。定時(shi)(shi)(shi)器(qi)可(ke)由時(shi)(shi)(shi)間繼(ji)電(dian)(dian)(dian)(dian)器(qi)充(chong)(chong)(chong)(chong)當，或(huo)者由單片機承擔其功能(neng)。這種方(fang)法簡單，但充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間不能(neng)根(gen)據電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)前狀態而自動調整，因此(ci)實際(ji)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)，可(ke)能(neng)會出(chu)現有(you)時(shi)(shi)(shi)欠(qian)充(chong)(chong)(chong)(chong)、有(you)時(shi)(shi)(shi)過充(chong)(chong)(chong)(chong)的(de)現象；
（2）電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度控制對(dui)Ni-cd電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而言，正常(chang)充(chong)電(dian)(dian)(dian)(dian)(dian)時，蓄電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)溫(wen)(wen)(wen)度變(bian)化(hua)并不明顯(xian)，但是，當電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)過充(chong)時，其內(nei)部(bu)氣(qi)體壓力(li)將迅速(su)增大，負(fu)極板(ban)上氧化(hua)反應使內(nei)部(bu)發熱，溫(wen)(wen)(wen)度迅速(su)上升(sheng)(sheng)（每分鐘可(ke)升(sheng)(sheng)高(gao)幾個(ge)攝(she)氏(shi)度）。因(yin)此，觀察電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度的(de)變(bian)化(hua)，即可(ke)判斷電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是否已經(jing)充(chong)滿(man)(man)。通常(chang)采用兩只熱敏電(dian)(dian)(dian)(dian)(dian)阻分別(bie)檢測電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度和環境溫(wen)(wen)(wen)度，當兩者溫(wen)(wen)(wen)差(cha)達到(dao)一定值時，即發出停充(chong)信號。由于(yu)熱敏電(dian)(dian)(dian)(dian)(dian)阻動(dong)態(tai)響應速(su)度較慢，故不能及時準確地檢測到(dao)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)滿(man)(man)充(chong)狀(zhuang)態(tai)；
（3）電池端電壓負增量控制一般而言，當電池充足電后，其端電壓將呈現下降趨勢，據此可將電池電壓出現負增長的時刻作為停充時刻。與溫度控制法相比，這種方法響應速度快，此外，電壓的負增量與電壓的絕對值無關，因此這種停充控制方法可適應具有不同單格電池數的蓄電池組充電。此方法的缺點是一般的檢測器靈敏度和可靠性不高，同時，當環境溫度較高時，電池充足電后電壓的減小并不明顯，因而難以控制。上海施能(neng)電(dian)器設備有限公司始建于(yu)1984年，上海市高新技術企業，中國工業車輛優秀配套供應商，上海電器行業名優產品，主要生產工頻系列充電機，高頻系列充電機，鋰電池充電機，系列放電機，系列充放電機等電器產品。
（1）定時(shi)(shi)(shi)控制采用恒流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)法時(shi)(shi)(shi)，電(dian)(dian)(dian)(dian)池(chi)所需充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間可(ke)根(gen)據電(dian)(dian)(dian)(dian)池(chi)容(rong)量和充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)的(de)大小(xiao)很容(rong)易地(di)確(que)定，因此(ci)只(zhi)要預先設定好(hao)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間，一旦時(shi)(shi)(shi)間一到，定時(shi)(shi)(shi)器(qi)即可(ke)發出(chu)信號停充(chong)(chong)(chong)(chong)或(huo)降為(wei)涓流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。定時(shi)(shi)(shi)器(qi)可(ke)由時(shi)(shi)(shi)間繼(ji)電(dian)(dian)(dian)(dian)器(qi)充(chong)(chong)(chong)(chong)當，或(huo)者由單片機承擔其功能(neng)。這種方(fang)法簡單，但充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間不能(neng)根(gen)據電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)前狀態而自動調整，因此(ci)實際(ji)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)，可(ke)能(neng)會出(chu)現有(you)時(shi)(shi)(shi)欠(qian)充(chong)(chong)(chong)(chong)、有(you)時(shi)(shi)(shi)過充(chong)(chong)(chong)(chong)的(de)現象；
（2）電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度控制對(dui)Ni-cd電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而言，正常(chang)充(chong)電(dian)(dian)(dian)(dian)(dian)時，蓄電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)溫(wen)(wen)(wen)度變(bian)化(hua)并不明顯(xian)，但是，當電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)過充(chong)時，其內(nei)部(bu)氣(qi)體壓力(li)將迅速(su)增大，負(fu)極板(ban)上氧化(hua)反應使內(nei)部(bu)發熱，溫(wen)(wen)(wen)度迅速(su)上升(sheng)(sheng)（每分鐘可(ke)升(sheng)(sheng)高(gao)幾個(ge)攝(she)氏(shi)度）。因(yin)此，觀察電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度的(de)變(bian)化(hua)，即可(ke)判斷電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是否已經(jing)充(chong)滿(man)(man)。通常(chang)采用兩只熱敏電(dian)(dian)(dian)(dian)(dian)阻分別(bie)檢測電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度和環境溫(wen)(wen)(wen)度，當兩者溫(wen)(wen)(wen)差(cha)達到(dao)一定值時，即發出停充(chong)信號。由于(yu)熱敏電(dian)(dian)(dian)(dian)(dian)阻動(dong)態(tai)響應速(su)度較慢，故不能及時準確地檢測到(dao)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)滿(man)(man)充(chong)狀(zhuang)態(tai)；
