當(dang)蓄電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)足電(dian)(dian)(dian)(dian)后(hou)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機必須(xu)適時地切斷充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流，否(fou)則蓄電(dian)(dian)(dian)(dian)池將(jiang)出現大(da)量出氣、失水和溫(wen)升(sheng)等過充(chong)(chong)(chong)(chong)反應，直接危(wei)及蓄電(dian)(dian)(dian)(dian)池的使(shi)用壽命。因此，必須(xu)隨時監測蓄電(dian)(dian)(dian)(dian)池的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)狀況(kuang)，保證電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)足電(dian)(dian)(dian)(dian)而又(you)不過充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。主要的停充(chong)(chong)(chong)(chong)控制(zhi)方法有：
（1）定(ding)時(shi)(shi)(shi)控(kong)制采用恒流(liu)充(chong)(chong)(chong)(chong)電(dian)法時(shi)(shi)(shi)，電(dian)池所需(xu)充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)間可(ke)根據(ju)電(dian)池容(rong)量和(he)充(chong)(chong)(chong)(chong)電(dian)電(dian)流(liu)的大小很容(rong)易地確定(ding)，因此(ci)只要預先設(she)定(ding)好充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)間，一旦時(shi)(shi)(shi)間一到，定(ding)時(shi)(shi)(shi)器(qi)即可(ke)發出信號停充(chong)(chong)(chong)(chong)或降為涓流(liu)充(chong)(chong)(chong)(chong)電(dian)。定(ding)時(shi)(shi)(shi)器(qi)可(ke)由(you)時(shi)(shi)(shi)間繼(ji)電(dian)器(qi)充(chong)(chong)(chong)(chong)當，或者由(you)單片機(ji)承擔其功能(neng)。這種方(fang)法簡(jian)單，但充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)間不(bu)能(neng)根據(ju)電(dian)池充(chong)(chong)(chong)(chong)電(dian)前狀態而自動調整，因此(ci)實(shi)際充(chong)(chong)(chong)(chong)電(dian)時(shi)(shi)(shi)，可(ke)能(neng)會出現有時(shi)(shi)(shi)欠充(chong)(chong)(chong)(chong)、有時(shi)(shi)(shi)過充(chong)(chong)(chong)(chong)的現象；
（2）電(dian)(dian)(dian)池(chi)(chi)溫(wen)度(du)(du)(du)控(kong)制對Ni-cd電(dian)(dian)(dian)池(chi)(chi)而(er)言，正常(chang)充電(dian)(dian)(dian)時(shi)(shi)，蓄電(dian)(dian)(dian)池(chi)(chi)的溫(wen)度(du)(du)(du)變化(hua)并不明顯(xian)，但是(shi)，當電(dian)(dian)(dian)池(chi)(chi)過充時(shi)(shi)，其內部氣體壓(ya)力將迅速增大，負極(ji)板(ban)上氧(yang)化(hua)反應使內部發熱(re)，溫(wen)度(du)(du)(du)迅速上升（每(mei)分(fen)鐘(zhong)可升高幾個攝氏度(du)(du)(du)）。因此，觀察電(dian)(dian)(dian)池(chi)(chi)溫(wen)度(du)(du)(du)的變化(hua)，即可判(pan)斷(duan)電(dian)(dian)(dian)池(chi)(chi)是(shi)否已(yi)經(jing)充滿。通常(chang)采(cai)用兩只熱(re)敏(min)電(dian)(dian)(dian)阻(zu)(zu)分(fen)別檢測(ce)(ce)電(dian)(dian)(dian)池(chi)(chi)溫(wen)度(du)(du)(du)和環境(jing)溫(wen)度(du)(du)(du)，當兩者溫(wen)差達到一定值時(shi)(shi)，即發出停充信號。由于熱(re)敏(min)電(dian)(dian)(dian)阻(zu)(zu)動(dong)態響應速度(du)(du)(du)較(jiao)慢，故不能及時(shi)(shi)準確地檢測(ce)(ce)到電(dian)(dian)(dian)池(chi)(chi)的滿充狀態；
（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(shang)海施能電(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。
