處理蓄(xu)電池(chi)充電機突然停(ting)電的方法
    當蓄(xu)電(dian)(dian)池充(chong)(chong)足電(dian)(dian)后,充(chong)(chong)電(dian)(dian)機必須(xu)(xu)適(shi)時地切斷充(chong)(chong)電(dian)(dian)電(dian)(dian)流,否則(ze)蓄(xu)電(dian)(dian)池將(jiang)出現大量出氣、失水(shui)和溫升等(deng)過充(chong)(chong)反應,直接危及蓄(xu)電(dian)(dian)池的使用壽命。因此,必須(xu)(xu)隨時監(jian)測蓄(xu)電(dian)(dian)池的充(chong)(chong)電(dian)(dian)狀(zhuang)況,保證電(dian)(dian)池充(chong)(chong)足電(dian)(dian)而又不過充(chong)(chong)電(dian)(dian)。主要(yao)的停(ting)充(chong)(chong)控制(zhi)方(fang)法(fa)有:
(1)定時(shi)控制采(cai)用恒流充(chong)(chong)電(dian)(dian)(dian)法(fa)時(shi),電(dian)(dian)(dian)池(chi)(chi)所需充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)可(ke)(ke)根據電(dian)(dian)(dian)池(chi)(chi)容量和充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的大小很容易地(di)確(que)定,因(yin)此(ci)只要預先(xian)設定好充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian),一旦時(shi)間(jian)一到,定時(shi)器(qi)即可(ke)(ke)發出信號停充(chong)(chong)或降為涓流充(chong)(chong)電(dian)(dian)(dian)。定時(shi)器(qi)可(ke)(ke)由時(shi)間(jian)繼電(dian)(dian)(dian)器(qi)充(chong)(chong)當,或者由單片機承擔其(qi)功(gong)能。這種方(fang)法(fa)簡單,但充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)不(bu)能根據電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)前狀態(tai)而自(zi)動調(diao)整,因(yin)此(ci)實際充(chong)(chong)電(dian)(dian)(dian)時(shi),可(ke)(ke)能會出現(xian)有時(shi)欠(qian)充(chong)(chong)、有時(shi)過充(chong)(chong)的現(xian)象;
(2)電(dian)(dian)(dian)(dian)池(chi)溫(wen)(wen)度(du)控(kong)制對Ni-cd電(dian)(dian)(dian)(dian)池(chi)而言,正(zheng)常充電(dian)(dian)(dian)(dian)時,蓄電(dian)(dian)(dian)(dian)池(chi)的溫(wen)(wen)度(du)變化(hua)并不明顯(xian),但是(shi),當電(dian)(dian)(dian)(dian)池(chi)過(guo)充時,其(qi)內部(bu)氣體壓力將迅(xun)速增大,負極板(ban)上氧化(hua)反(fan)應(ying)使內部(bu)發熱(re),溫(wen)(wen)度(du)迅(xun)速上升(每分(fen)鐘可升高幾個攝氏(shi)度(du))。因此,觀察電(dian)(dian)(dian)(dian)池(chi)溫(wen)(wen)度(du)的變化(hua),即可判斷電(dian)(dian)(dian)(dian)池(chi)是(shi)否已經充滿(man)(man)。通常采用兩(liang)(liang)只熱(re)敏電(dian)(dian)(dian)(dian)阻(zu)分(fen)別檢(jian)測電(dian)(dian)(dian)(dian)池(chi)溫(wen)(wen)度(du)和(he)環境(jing)溫(wen)(wen)度(du),當兩(liang)(liang)者溫(wen)(wen)差(cha)達到一定值時,即發出停充信號。由于熱(re)敏電(dian)(dian)(dian)(dian)阻(zu)動態響應(ying)速度(du)較慢,故不能(neng)及時準(zhun)確地(di)檢(jian)測到電(dian)(dian)(dian)(dian)池(chi)的滿(man)(man)充狀(zhuang)態;
(3)電(dian)(dian)(dian)(dian)池端電(dian)(dian)(dian)(dian)壓負(fu)(fu)增(zeng)量控(kong)(kong)制(zhi)(zhi)一般而言,當電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)足電(dian)(dian)(dian)(dian)后,其端電(dian)(dian)(dian)(dian)壓將(jiang)(jiang)呈現(xian)(xian)下降(jiang)趨勢,據此(ci)(ci)可將(jiang)(jiang)電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓出現(xian)(xian)負(fu)(fu)增(zeng)長的(de)(de)時(shi)(shi)刻(ke)作為(wei)停充(chong)(chong)(chong)時(shi)(shi)刻(ke)。與溫(wen)度(du)控(kong)(kong)制(zhi)(zhi)法相比,這種方法響(xiang)應(ying)速度(du)快,此(ci)(ci)外,電(dian)(dian)(dian)(dian)壓的(de)(de)負(fu)(fu)增(zeng)量與電(dian)(dian)(dian)(dian)壓的(de)(de)絕(jue)對值無關,因(yin)此(ci)(ci)這種停充(chong)(chong)(chong)控(kong)(kong)制(zhi)(zhi)方法可適應(ying)具有(you)不同單格電(dian)(dian)(dian)(dian)池數的(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)池組充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。此(ci)(ci)方法的(de)(de)缺點是一般的(de)(de)檢測器靈(ling)敏度(du)和可靠性不高,同時(shi)(shi),當環境(jing)溫(wen)度(du)較(jiao)高時(shi)(shi),電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)足電(dian)(dian)(dian)(dian)后電(dian)(dian)(dian)(dian)壓的(de)(de)減(jian)小(xiao)并不明顯,因(yin)而難以控(kong)(kong)制(zhi)(zhi)。
