當蓄(xu)電(dian)(dian)池(chi)(chi)充(chong)足(zu)電(dian)(dian)后，充(chong)電(dian)(dian)機必(bi)須適時(shi)地切(qie)斷充(chong)電(dian)(dian)電(dian)(dian)流，否則蓄(xu)電(dian)(dian)池(chi)(chi)將出現大量出氣、失(shi)水和溫(wen)升(sheng)等過(guo)充(chong)反(fan)應(ying)，直(zhi)接危及蓄(xu)電(dian)(dian)池(chi)(chi)的(de)使用壽命。因此(ci)，必(bi)須隨時(shi)監測蓄(xu)電(dian)(dian)池(chi)(chi)的(de)充(chong)電(dian)(dian)狀(zhuang)況(kuang)，保證電(dian)(dian)池(chi)(chi)充(chong)足(zu)電(dian)(dian)而又不過(guo)充(chong)電(dian)(dian)。主要的(de)停充(chong)控制方法有：
（1）定(ding)(ding)時(shi)(shi)(shi)(shi)控制采用恒流充(chong)(chong)電(dian)(dian)法時(shi)(shi)(shi)(shi)，電(dian)(dian)池所需(xu)充(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)(shi)間(jian)可根據電(dian)(dian)池容量和充(chong)(chong)電(dian)(dian)電(dian)(dian)流的(de)大小很(hen)容易地確(que)定(ding)(ding)，因(yin)此只(zhi)要預先設定(ding)(ding)好(hao)充(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)(shi)間(jian)，一旦時(shi)(shi)(shi)(shi)間(jian)一到(dao)，定(ding)(ding)時(shi)(shi)(shi)(shi)器即可發出信號停充(chong)(chong)或(huo)降為涓流充(chong)(chong)電(dian)(dian)。定(ding)(ding)時(shi)(shi)(shi)(shi)器可由(you)時(shi)(shi)(shi)(shi)間(jian)繼(ji)電(dian)(dian)器充(chong)(chong)當，或(huo)者(zhe)由(you)單片機承擔其功(gong)能(neng)。這種方(fang)法簡單，但充(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)(shi)間(jian)不能(neng)根據電(dian)(dian)池充(chong)(chong)電(dian)(dian)前狀態而自動(dong)調整，因(yin)此實際充(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)(shi)，可能(neng)會(hui)出現有時(shi)(shi)(shi)(shi)欠(qian)充(chong)(chong)、有時(shi)(shi)(shi)(shi)過充(chong)(chong)的(de)現象(xiang)；
（2）電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度控制(zhi)對Ni-cd電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)而(er)言，正常充(chong)電(dian)(dian)(dian)(dian)時(shi)，蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)溫(wen)(wen)(wen)度變(bian)化(hua)并不明顯，但是，當電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)過(guo)充(chong)時(shi)，其內(nei)部氣體壓力(li)將迅(xun)速(su)(su)增大，負極板上氧化(hua)反(fan)應(ying)使內(nei)部發熱(re)，溫(wen)(wen)(wen)度迅(xun)速(su)(su)上升(sheng)（每分(fen)鐘(zhong)可升(sheng)高幾個攝氏度）。因(yin)此，觀察電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度的(de)(de)變(bian)化(hua)，即(ji)可判斷電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是否已(yi)經充(chong)滿。通常采用兩只熱(re)敏電(dian)(dian)(dian)(dian)阻分(fen)別(bie)檢測電(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)差達到一定值時(shi)，即(ji)發出停充(chong)信號。由于熱(re)敏電(dian)(dian)(dian)(dian)阻動態響應(ying)速(su)(su)度較慢，故(gu)不能(neng)及時(shi)準確地檢測到電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)滿充(chong)狀態；
（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。上海施能電器設(she)備(bei)有限公司始建于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。
