當蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)足(zu)電(dian)(dian)(dian)(dian)(dian)后，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)機必(bi)須適時地切斷充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，否則(ze)蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)將出現大量出氣、失水和溫升等過充(chong)(chong)(chong)(chong)反(fan)應，直接(jie)危(wei)及蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的使用壽(shou)命。因此(ci)，必(bi)須隨(sui)時監(jian)測蓄(xu)(xu)(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)狀(zhuang)況，保(bao)證(zheng)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)足(zu)電(dian)(dian)(dian)(dian)(dian)而又不過充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。主(zhu)要的停充(chong)(chong)(chong)(chong)控制方(fang)法有：
（1）定(ding)時(shi)(shi)(shi)控制采用恒流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)法(fa)時(shi)(shi)(shi)，電(dian)(dian)池(chi)所(suo)需充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)間可(ke)根據(ju)電(dian)(dian)池(chi)容量(liang)和(he)充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)的大小很容易地確(que)定(ding)，因此只要預(yu)先設定(ding)好充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)間，一(yi)旦時(shi)(shi)(shi)間一(yi)到，定(ding)時(shi)(shi)(shi)器(qi)(qi)即可(ke)發出信號停充(chong)(chong)(chong)(chong)或降(jiang)為(wei)涓流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)。定(ding)時(shi)(shi)(shi)器(qi)(qi)可(ke)由(you)時(shi)(shi)(shi)間繼(ji)電(dian)(dian)器(qi)(qi)充(chong)(chong)(chong)(chong)當，或者由(you)單片機承擔其功能(neng)。這種(zhong)方法(fa)簡單，但充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)間不能(neng)根據(ju)電(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)前(qian)狀態而(er)自(zi)動調整，因此實際(ji)充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)(shi)(shi)，可(ke)能(neng)會(hui)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(xiang)；
（2）電(dian)(dian)(dian)(dian)(dian)池(chi)溫度(du)控制對(dui)Ni-cd電(dian)(dian)(dian)(dian)(dian)池(chi)而言，正常(chang)充電(dian)(dian)(dian)(dian)(dian)時，蓄電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)溫度(du)變化并(bing)不明顯，但是，當電(dian)(dian)(dian)(dian)(dian)池(chi)過充時，其內(nei)部氣體(ti)壓力(li)將迅(xun)速增(zeng)大，負極(ji)板(ban)上氧化反應使(shi)內(nei)部發(fa)熱，溫度(du)迅(xun)速上升（每分鐘可升高幾個攝(she)氏度(du)）。因(yin)此，觀察(cha)電(dian)(dian)(dian)(dian)(dian)池(chi)溫度(du)的(de)變化，即(ji)(ji)可判斷電(dian)(dian)(dian)(dian)(dian)池(chi)是否已經充滿。通常(chang)采用(yong)兩只熱敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)分別(bie)檢測(ce)電(dian)(dian)(dian)(dian)(dian)池(chi)溫度(du)和環(huan)境(jing)溫度(du)，當兩者溫差達到一(yi)定值時，即(ji)(ji)發(fa)出停(ting)充信號。由于熱敏(min)電(dian)(dian)(dian)(dian)(dian)阻(zu)動(dong)態響應速度(du)較慢，故不能及時準確地檢測(ce)到電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)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。上海施能電器設備有限公(gong)司始(shi)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。
