處理蓄電(dian)池充電(dian)機(ji)突然停(ting)電(dian)的方(fang)法
當(dang)蓄電(dian)(dian)(dian)池(chi)(chi)充足電(dian)(dian)(dian)后，充電(dian)(dian)(dian)機必須適時(shi)地切斷充電(dian)(dian)(dian)電(dian)(dian)(dian)流，否則蓄電(dian)(dian)(dian)池(chi)(chi)將出(chu)現大量出(chu)氣(qi)、失(shi)水和溫升等過(guo)充反應，直接危及蓄電(dian)(dian)(dian)池(chi)(chi)的(de)使用(yong)壽命。因(yin)此，必須隨時(shi)監測蓄電(dian)(dian)(dian)池(chi)(chi)的(de)充電(dian)(dian)(dian)狀況，保證電(dian)(dian)(dian)池(chi)(chi)充足電(dian)(dian)(dian)而又不過(guo)充電(dian)(dian)(dian)。主要的(de)停充控制(zhi)方法有：
（1）定(ding)時(shi)控制采用恒流充(chong)(chong)(chong)電(dian)(dian)(dian)法(fa)時(shi)，電(dian)(dian)(dian)池所需充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間可(ke)根(gen)據(ju)電(dian)(dian)(dian)池容量和充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的(de)大(da)小很容易地確定(ding)，因此(ci)(ci)只要預先設定(ding)好充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間，一旦時(shi)間一到，定(ding)時(shi)器即可(ke)發出信號停充(chong)(chong)(chong)或降為涓流充(chong)(chong)(chong)電(dian)(dian)(dian)。定(ding)時(shi)器可(ke)由(you)時(shi)間繼電(dian)(dian)(dian)器充(chong)(chong)(chong)當，或者(zhe)由(you)單(dan)片機承擔其功能。這種方法(fa)簡單(dan)，但充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間不能根(gen)據(ju)電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)前狀態而自動調整，因此(ci)(ci)實際充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)，可(ke)能會出現有時(shi)欠充(chong)(chong)(chong)、有時(shi)過充(chong)(chong)(chong)的(de)現象(xiang)；
（2）電(dian)池(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)控制(zhi)對Ni-cd電(dian)池(chi)(chi)而(er)言，正(zheng)常(chang)充(chong)電(dian)時(shi)，蓄電(dian)池(chi)(chi)的溫(wen)(wen)(wen)(wen)度(du)(du)變(bian)化并不明顯(xian)，但是，當電(dian)池(chi)(chi)過充(chong)時(shi)，其內部(bu)氣體壓力將迅(xun)速增大，負極板上氧(yang)化反(fan)應(ying)(ying)使內部(bu)發(fa)熱(re)，溫(wen)(wen)(wen)(wen)度(du)(du)迅(xun)速上升（每分鐘(zhong)可升高(gao)幾個攝氏度(du)(du)）。因此，觀察(cha)電(dian)池(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)的變(bian)化，即可判斷電(dian)池(chi)(chi)是否已經充(chong)滿。通常(chang)采用兩只(zhi)熱(re)敏電(dian)阻分別檢(jian)測(ce)電(dian)池(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)和(he)環境溫(wen)(wen)(wen)(wen)度(du)(du)，當兩者溫(wen)(wen)(wen)(wen)差達(da)到(dao)一定值時(shi)，即發(fa)出停充(chong)信號。由于熱(re)敏電(dian)阻動態(tai)響(xiang)應(ying)(ying)速度(du)(du)較(jiao)慢(man)，故不能及(ji)時(shi)準確(que)地檢(jian)測(ce)到(dao)電(dian)池(chi)(chi)的滿充(chong)狀(zhuang)態(tai)；
（3）電(dian)(dian)(dian)(dian)池(chi)端電(dian)(dian)(dian)(dian)壓負增(zeng)量(liang)控制(zhi)(zhi)一(yi)般而(er)言，當(dang)電(dian)(dian)(dian)(dian)池(chi)充足電(dian)(dian)(dian)(dian)后(hou)，其端電(dian)(dian)(dian)(dian)壓將(jiang)呈現下降趨勢，據此(ci)可(ke)將(jiang)電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓出現負增(zeng)長的(de)時刻作(zuo)為(wei)停(ting)充時刻。與溫度(du)控制(zhi)(zhi)法(fa)相比，這種方(fang)法(fa)響應速度(du)快，此(ci)外，電(dian)(dian)(dian)(dian)壓的(de)負增(zeng)量(liang)與電(dian)(dian)(dian)(dian)壓的(de)絕對值(zhi)無關(guan)，因此(ci)這種停(ting)充控制(zhi)(zhi)方(fang)法(fa)可(ke)適應具有(you)不(bu)同(tong)單格電(dian)(dian)(dian)(dian)池(chi)數的(de)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)組充電(dian)(dian)(dian)(dian)。此(ci)方(fang)法(fa)的(de)缺點是一(yi)般的(de)檢測器靈敏度(du)和(he)可(ke)靠性(xing)不(bu)高，同(tong)時，當(dang)環境(jing)溫度(du)較高時，電(dian)(dian)(dian)(dian)池(chi)充足電(dian)(dian)(dian)(dian)后(hou)電(dian)(dian)(dian)(dian)壓的(de)減小并不(bu)明顯，因而(er)難以(yi)控制(zhi)(zhi)。
當(dang)蓄電(dian)(dian)(dian)池(chi)(chi)充足電(dian)(dian)(dian)后，充電(dian)(dian)(dian)機必須適時(shi)地切斷充電(dian)(dian)(dian)電(dian)(dian)(dian)流，否則蓄電(dian)(dian)(dian)池(chi)(chi)將出(chu)現大量出(chu)氣(qi)、失(shi)水和溫升等過(guo)充反應，直接危及蓄電(dian)(dian)(dian)池(chi)(chi)的(de)使用(yong)壽命。因(yin)此，必須隨時(shi)監測蓄電(dian)(dian)(dian)池(chi)(chi)的(de)充電(dian)(dian)(dian)狀況，保證電(dian)(dian)(dian)池(chi)(chi)充足電(dian)(dian)(dian)而又不過(guo)充電(dian)(dian)(dian)。主要的(de)停充控制(zhi)方法有：
（1）定(ding)時(shi)控制采用恒流充(chong)(chong)(chong)電(dian)(dian)(dian)法(fa)時(shi)，電(dian)(dian)(dian)池所需充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間可(ke)根(gen)據(ju)電(dian)(dian)(dian)池容量和充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的(de)大(da)小很容易地確定(ding)，因此(ci)(ci)只要預先設定(ding)好充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間，一旦時(shi)間一到，定(ding)時(shi)器即可(ke)發出信號停充(chong)(chong)(chong)或降為涓流充(chong)(chong)(chong)電(dian)(dian)(dian)。定(ding)時(shi)器可(ke)由(you)時(shi)間繼電(dian)(dian)(dian)器充(chong)(chong)(chong)當，或者(zhe)由(you)單(dan)片機承擔其功能。這種方法(fa)簡單(dan)，但充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)間不能根(gen)據(ju)電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)前狀態而自動調整，因此(ci)(ci)實際充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)，可(ke)能會出現有時(shi)欠充(chong)(chong)(chong)、有時(shi)過充(chong)(chong)(chong)的(de)現象(xiang)；
（2）電(dian)池(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)控制(zhi)對Ni-cd電(dian)池(chi)(chi)而(er)言，正(zheng)常(chang)充(chong)電(dian)時(shi)，蓄電(dian)池(chi)(chi)的溫(wen)(wen)(wen)(wen)度(du)(du)變(bian)化并不明顯(xian)，但是，當電(dian)池(chi)(chi)過充(chong)時(shi)，其內部(bu)氣體壓力將迅(xun)速增大，負極板上氧(yang)化反(fan)應(ying)(ying)使內部(bu)發(fa)熱(re)，溫(wen)(wen)(wen)(wen)度(du)(du)迅(xun)速上升（每分鐘(zhong)可升高(gao)幾個攝氏度(du)(du)）。因此，觀察(cha)電(dian)池(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)的變(bian)化，即可判斷電(dian)池(chi)(chi)是否已經充(chong)滿。通常(chang)采用兩只(zhi)熱(re)敏電(dian)阻分別檢(jian)測(ce)電(dian)池(chi)(chi)溫(wen)(wen)(wen)(wen)度(du)(du)和(he)環境溫(wen)(wen)(wen)(wen)度(du)(du)，當兩者溫(wen)(wen)(wen)(wen)差達(da)到(dao)一定值時(shi)，即發(fa)出停充(chong)信號。由于熱(re)敏電(dian)阻動態(tai)響(xiang)應(ying)(ying)速度(du)(du)較(jiao)慢(man)，故不能及(ji)時(shi)準確(que)地檢(jian)測(ce)到(dao)電(dian)池(chi)(chi)的滿充(chong)狀(zhuang)態(tai)；
（3）電(dian)(dian)(dian)(dian)池(chi)端電(dian)(dian)(dian)(dian)壓負增(zeng)量(liang)控制(zhi)(zhi)一(yi)般而(er)言，當(dang)電(dian)(dian)(dian)(dian)池(chi)充足電(dian)(dian)(dian)(dian)后(hou)，其端電(dian)(dian)(dian)(dian)壓將(jiang)呈現下降趨勢，據此(ci)可(ke)將(jiang)電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓出現負增(zeng)長的(de)時刻作(zuo)為(wei)停(ting)充時刻。與溫度(du)控制(zhi)(zhi)法(fa)相比，這種方(fang)法(fa)響應速度(du)快，此(ci)外，電(dian)(dian)(dian)(dian)壓的(de)負增(zeng)量(liang)與電(dian)(dian)(dian)(dian)壓的(de)絕對值(zhi)無關(guan)，因此(ci)這種停(ting)充控制(zhi)(zhi)方(fang)法(fa)可(ke)適應具有(you)不(bu)同(tong)單格電(dian)(dian)(dian)(dian)池(chi)數的(de)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)組充電(dian)(dian)(dian)(dian)。此(ci)方(fang)法(fa)的(de)缺點是一(yi)般的(de)檢測器靈敏度(du)和(he)可(ke)靠性(xing)不(bu)高，同(tong)時，當(dang)環境(jing)溫度(du)較高時，電(dian)(dian)(dian)(dian)池(chi)充足電(dian)(dian)(dian)(dian)后(hou)電(dian)(dian)(dian)(dian)壓的(de)減小并不(bu)明顯，因而(er)難以(yi)控制(zhi)(zhi)。
