當(dang)蓄(xu)電(dian)(dian)(dian)池(chi)充(chong)足電(dian)(dian)(dian)后，充(chong)電(dian)(dian)(dian)機必須(xu)適(shi)時地(di)切斷充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流，否則蓄(xu)電(dian)(dian)(dian)池(chi)將出現大量出氣、失水(shui)和溫升(sheng)等過(guo)充(chong)反(fan)應，直接危及蓄(xu)電(dian)(dian)(dian)池(chi)的(de)使用壽命。因此，必須(xu)隨(sui)時監(jian)測(ce)蓄(xu)電(dian)(dian)(dian)池(chi)的(de)充(chong)電(dian)(dian)(dian)狀況，保證電(dian)(dian)(dian)池(chi)充(chong)足電(dian)(dian)(dian)而(er)又不過(guo)充(chong)電(dian)(dian)(dian)。主要(yao)的(de)停充(chong)控制方法有：
（1）定(ding)時(shi)(shi)(shi)控制采用恒流(liu)(liu)充(chong)電(dian)(dian)法(fa)時(shi)(shi)(shi)，電(dian)(dian)池(chi)(chi)所需(xu)充(chong)電(dian)(dian)時(shi)(shi)(shi)間(jian)可(ke)根(gen)據(ju)電(dian)(dian)池(chi)(chi)容量和(he)充(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)的大小很容易地確定(ding)，因(yin)此只(zhi)要預先設(she)定(ding)好充(chong)電(dian)(dian)時(shi)(shi)(shi)間(jian)，一(yi)旦時(shi)(shi)(shi)間(jian)一(yi)到(dao)，定(ding)時(shi)(shi)(shi)器即可(ke)發出(chu)信號停充(chong)或降(jiang)為涓流(liu)(liu)充(chong)電(dian)(dian)。定(ding)時(shi)(shi)(shi)器可(ke)由(you)(you)時(shi)(shi)(shi)間(jian)繼(ji)電(dian)(dian)器充(chong)當(dang)，或者由(you)(you)單片機(ji)承擔其功能。這種方(fang)法(fa)簡單，但充(chong)電(dian)(dian)時(shi)(shi)(shi)間(jian)不能根(gen)據(ju)電(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)前狀態(tai)而自動調整，因(yin)此實(shi)際充(chong)電(dian)(dian)時(shi)(shi)(shi)，可(ke)能會出(chu)現有(you)時(shi)(shi)(shi)欠充(chong)、有(you)時(shi)(shi)(shi)過充(chong)的現象；
（2）電(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)控(kong)制對Ni-cd電(dian)(dian)池(chi)(chi)(chi)而言，正常(chang)充(chong)(chong)電(dian)(dian)時(shi)(shi)，蓄電(dian)(dian)池(chi)(chi)(chi)的(de)溫(wen)(wen)(wen)(wen)度(du)(du)(du)變(bian)化(hua)并不明顯(xian)，但是(shi)(shi)，當電(dian)(dian)池(chi)(chi)(chi)過充(chong)(chong)時(shi)(shi)，其(qi)內(nei)部氣體壓(ya)力將迅速(su)(su)(su)增大，負極板上氧化(hua)反應(ying)使(shi)內(nei)部發(fa)熱(re)(re)，溫(wen)(wen)(wen)(wen)度(du)(du)(du)迅速(su)(su)(su)上升（每分(fen)鐘可(ke)(ke)升高幾(ji)個攝氏度(du)(du)(du)）。因此，觀察電(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)的(de)變(bian)化(hua)，即可(ke)(ke)判斷(duan)電(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)否已經充(chong)(chong)滿。通常(chang)采用兩(liang)只熱(re)(re)敏電(dian)(dian)阻分(fen)別(bie)檢測電(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)和環境溫(wen)(wen)(wen)(wen)度(du)(du)(du)，當兩(liang)者溫(wen)(wen)(wen)(wen)差達到(dao)一定值時(shi)(shi)，即發(fa)出停充(chong)(chong)信號(hao)。由于熱(re)(re)敏電(dian)(dian)阻動(dong)態響應(ying)速(su)(su)(su)度(du)(du)(du)較慢，故不能及時(shi)(shi)準確地檢測到(dao)電(dian)(dian)池(chi)(chi)(chi)的(de)滿充(chong)(chong)狀(zhuang)態；
（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。上海施能電(dian)器設(she)備有限公司始建(jian)于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。

（2）電(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)控(kong)制對Ni-cd電(dian)(dian)池(chi)(chi)(chi)而言，正常(chang)充(chong)(chong)電(dian)(dian)時(shi)(shi)，蓄電(dian)(dian)池(chi)(chi)(chi)的(de)溫(wen)(wen)(wen)(wen)度(du)(du)(du)變(bian)化(hua)并不明顯(xian)，但是(shi)(shi)，當電(dian)(dian)池(chi)(chi)(chi)過充(chong)(chong)時(shi)(shi)，其(qi)內(nei)部氣體壓(ya)力將迅速(su)(su)(su)增大，負極板上氧化(hua)反應(ying)使(shi)內(nei)部發(fa)熱(re)(re)，溫(wen)(wen)(wen)(wen)度(du)(du)(du)迅速(su)(su)(su)上升（每分(fen)鐘可(ke)(ke)升高幾(ji)個攝氏度(du)(du)(du)）。因此，觀察電(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)的(de)變(bian)化(hua)，即可(ke)(ke)判斷(duan)電(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)否已經充(chong)(chong)滿。通常(chang)采用兩(liang)只熱(re)(re)敏電(dian)(dian)阻分(fen)別(bie)檢測電(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)和環境溫(wen)(wen)(wen)(wen)度(du)(du)(du)，當兩(liang)者溫(wen)(wen)(wen)(wen)差達到(dao)一定值時(shi)(shi)，即發(fa)出停充(chong)(chong)信號(hao)。由于熱(re)(re)敏電(dian)(dian)阻動(dong)態響應(ying)速(su)(su)(su)度(du)(du)(du)較慢，故不能及時(shi)(shi)準確地檢測到(dao)電(dian)(dian)池(chi)(chi)(chi)的(de)滿充(chong)(chong)狀(zhuang)態；
