當蓄電(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)(chong)足電(dian)后，電(dian)單車充(chong)(chong)(chong)(chong)(chong)電(dian)站必需適時地切斷(duan)充(chong)(chong)(chong)(chong)(chong)電(dian)電(dian)流，否則蓄電(dian)池(chi)(chi)將呈現大量出氣、失水和溫升等(deng)過充(chong)(chong)(chong)(chong)(chong)反響，直接危(wei)及蓄電(dian)池(chi)(chi)的運用壽命。因而(er)，必需隨時監測(ce)蓄電(dian)池(chi)(chi)的充(chong)(chong)(chong)(chong)(chong)電(dian)情況，保證電(dian)池(chi)(chi)充(chong)(chong)(chong)(chong)(chong)足電(dian)而(er)又不過充(chong)(chong)(chong)(chong)(chong)電(dian)。主要的停(ting)充(chong)(chong)(chong)(chong)(chong)控制辦法有：
（1）定(ding)(ding)時(shi)(shi)控制采用(yong)恒流充(chong)(chong)(chong)電(dian)(dian)(dian)法時(shi)(shi)，電(dian)(dian)(dian)池(chi)所需充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)(jian)可(ke)依據(ju)電(dian)(dian)(dian)池(chi)容量和充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流的大(da)小很(hen)容易地(di)肯定(ding)(ding)，因而(er)只需預先設定(ding)(ding)好充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)(jian)，一旦時(shi)(shi)間(jian)(jian)一到，定(ding)(ding)時(shi)(shi)器即可(ke)發出信(xin)號停充(chong)(chong)(chong)或降為涓(juan)流充(chong)(chong)(chong)電(dian)(dian)(dian)。定(ding)(ding)時(shi)(shi)器可(ke)由時(shi)(shi)間(jian)(jian)繼電(dian)(dian)(dian)器充(chong)(chong)(chong)任，或者由單(dan)(dan)片機(ji)承當其功用(yong)。這(zhe)種辦法簡單(dan)(dan)，但充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)間(jian)(jian)不能依據(ju)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)前狀態而(er)自動調整(zheng)，因而(er)實踐充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)，可(ke)能會呈現有時(shi)(shi)欠充(chong)(chong)(chong)、有時(shi)(shi)過充(chong)(chong)(chong)的現象；
（2）電(dian)池(chi)(chi)(chi)(chi)溫(wen)度(du)(du)控制對Ni-cd電(dian)池(chi)(chi)(chi)(chi)而言，正(zheng)常充(chong)(chong)電(dian)時，蓄電(dian)池(chi)(chi)(chi)(chi)的溫(wen)度(du)(du)變化并不明顯，但是，當電(dian)池(chi)(chi)(chi)(chi)過充(chong)(chong)時，其(qi)內部氣體(ti)壓力將(jiang)疾速增大(da)，負極板上氧化反(fan)響(xiang)使內部發(fa)熱(re)，溫(wen)度(du)(du)疾速上升（每分鐘(zhong)可(ke)升高幾個攝氏度(du)(du)）。因而，察看電(dian)池(chi)(chi)(chi)(chi)溫(wen)度(du)(du)的變化，即可(ke)判(pan)別(bie)電(dian)池(chi)(chi)(chi)(chi)能(neng)(neng)否曾經充(chong)(chong)溢。通常采用(yong)兩只熱(re)敏電(dian)阻分別(bie)檢(jian)測(ce)電(dian)池(chi)(chi)(chi)(chi)溫(wen)度(du)(du)和環(huan)境溫(wen)度(du)(du)，當兩者溫(wen)差到(dao)達一定值時，即發(fa)出停充(chong)(chong)信號。由(you)于熱(re)敏電(dian)阻動態響(xiang)應速度(du)(du)較慢，故(gu)不能(neng)(neng)及時**地檢(jian)測(ce)到(dao)電(dian)池(chi)(chi)(chi)(chi)的滿充(chong)(chong)狀態；
（3）電(dian)(dian)(dian)(dian)池端(duan)電(dian)(dian)(dian)(dian)壓負(fu)增量控制普通(tong)而(er)(er)言，當電(dian)(dian)(dian)(dian)池充足電(dian)(dian)(dian)(dian)后，其端(duan)電(dian)(dian)(dian)(dian)壓將呈現降落趨向，據(ju)此(ci)可將電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓呈現負(fu)增長的(de)時辰(chen)(chen)作為停充時辰(chen)(chen)。與(yu)溫度控制法相(xiang)比，這(zhe)種(zhong)辦法響應(ying)速度快，此(ci)外，電(dian)(dian)(dian)(dian)壓的(de)負(fu)增量與(yu)電(dian)(dian)(dian)(dian)壓的(de)**值無關(guan)，因(yin)而(er)(er)這(zhe)種(zhong)停充控制辦法可順(shun)應(ying)具有不同(tong)單格電(dian)(dian)(dian)(dian)池數(shu)的(de)蓄電(dian)(dian)(dian)(dian)池組充電(dian)(dian)(dian)(dian)。此(ci)辦法的(de)缺陷是普通(tong)的(de)檢測器(qi)靈(ling)活度和牢靠性(xing)不高，同(tong)時，當環境溫度較高時，電(dian)(dian)(dian)(dian)池充足電(dian)(dian)(dian)(dian)后電(dian)(dian)(dian)(dian)壓的(de)減小并(bing)不明顯，因(yin)此(ci)難以控制。
