當蓄電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)足電(dian)(dian)(dian)(dian)(dian)后(hou)，電(dian)(dian)(dian)(dian)(dian)單車充(chong)電(dian)(dian)(dian)(dian)(dian)站必需適(shi)時(shi)地切(qie)斷充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流，否則蓄電(dian)(dian)(dian)(dian)(dian)池(chi)將呈現(xian)大量出(chu)氣、失水和(he)溫(wen)升等過(guo)充(chong)反響，直接危及(ji)蓄電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)運用壽命。因而(er)，必需隨時(shi)監測蓄電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)情況，保證電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)足電(dian)(dian)(dian)(dian)(dian)而(er)又不過(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)。主要的(de)停充(chong)控制辦法(fa)有(you)：
（1）定時(shi)控制(zhi)采用恒(heng)流(liu)(liu)充(chong)(chong)電(dian)(dian)法(fa)時(shi)，電(dian)(dian)池(chi)所需充(chong)(chong)電(dian)(dian)時(shi)間可(ke)依(yi)據電(dian)(dian)池(chi)容量和充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)的大小很容易地肯定，因而(er)只需預先(xian)設定好(hao)充(chong)(chong)電(dian)(dian)時(shi)間，一旦時(shi)間一到，定時(shi)器即可(ke)發(fa)出(chu)信號停充(chong)(chong)或(huo)降為(wei)涓流(liu)(liu)充(chong)(chong)電(dian)(dian)。定時(shi)器可(ke)由(you)時(shi)間繼電(dian)(dian)器充(chong)(chong)任，或(huo)者由(you)單(dan)片機承當其功用。這種辦法(fa)簡單(dan)，但充(chong)(chong)電(dian)(dian)時(shi)間不能(neng)依(yi)據電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)前狀態而(er)自動調整，因而(er)實踐充(chong)(chong)電(dian)(dian)時(shi)，可(ke)能(neng)會呈現(xian)有(you)時(shi)欠充(chong)(chong)、有(you)時(shi)過充(chong)(chong)的現(xian)象；
（2）電(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度(du)(du)控制對Ni-cd電(dian)池(chi)(chi)(chi)而言，正(zheng)常(chang)充電(dian)時(shi)，蓄電(dian)池(chi)(chi)(chi)的(de)(de)溫(wen)(wen)(wen)度(du)(du)變化并(bing)不明顯(xian)，但是，當電(dian)池(chi)(chi)(chi)過充時(shi)，其內部氣體(ti)壓力(li)將疾(ji)速(su)增大，負(fu)極(ji)板上(shang)氧化反(fan)響(xiang)使內部發熱，溫(wen)(wen)(wen)度(du)(du)疾(ji)速(su)上(shang)升(sheng)（每(mei)分(fen)鐘可升(sheng)高(gao)幾個攝氏度(du)(du)）。因而，察看電(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度(du)(du)的(de)(de)變化，即可判別電(dian)池(chi)(chi)(chi)能否曾(ceng)經充溢(yi)。通常(chang)采(cai)用兩只熱敏電(dian)阻(zu)分(fen)別檢(jian)測(ce)(ce)電(dian)池(chi)(chi)(chi)溫(wen)(wen)(wen)度(du)(du)和環境溫(wen)(wen)(wen)度(du)(du)，當兩者(zhe)溫(wen)(wen)(wen)差到達一(yi)定值時(shi)，即發出(chu)停(ting)充信號。由(you)于熱敏電(dian)阻(zu)動(dong)態響(xiang)應速(su)度(du)(du)較慢，故不能及時(shi)**地檢(jian)測(ce)(ce)到電(dian)池(chi)(chi)(chi)的(de)(de)滿充狀態；
（3）電(dian)(dian)(dian)池(chi)端(duan)電(dian)(dian)(dian)壓(ya)(ya)負(fu)增量(liang)控(kong)制(zhi)普通而(er)言，當電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)足電(dian)(dian)(dian)后，其(qi)端(duan)電(dian)(dian)(dian)壓(ya)(ya)將呈(cheng)(cheng)現降落趨向(xiang)，據此(ci)可將電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)(ya)呈(cheng)(cheng)現負(fu)增長的時(shi)辰(chen)作為停(ting)充(chong)(chong)(chong)時(shi)辰(chen)。與溫度(du)控(kong)制(zhi)法相比，這種(zhong)辦法響(xiang)應速(su)度(du)快，此(ci)外(wai)，電(dian)(dian)(dian)壓(ya)(ya)的負(fu)增量(liang)與電(dian)(dian)(dian)壓(ya)(ya)的**值無關(guan)，因而(er)這種(zhong)停(ting)充(chong)(chong)(chong)控(kong)制(zhi)辦法可順應具有不同(tong)單格電(dian)(dian)(dian)池(chi)數(shu)的蓄電(dian)(dian)(dian)池(chi)組充(chong)(chong)(chong)電(dian)(dian)(dian)。此(ci)辦法的缺陷是普通的檢測器(qi)靈活(huo)度(du)和牢靠性不高，同(tong)時(shi)，當環(huan)境溫度(du)較高時(shi)，電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)足電(dian)(dian)(dian)后電(dian)(dian)(dian)壓(ya)(ya)的減(jian)小并不明顯(xian)，因此(ci)難以控(kong)制(zhi)。
