電(dian)動車充(chong)電(dian)站在(zai)充(chong)電(dian)過程中，鉛(qian)(qian)酸電(dian)池(chi)(chi)(chi)負極板(ban)上(shang)(shang)的(de)硫(liu)酸鉛(qian)(qian)逐漸(jian)析(xi)出鉛(qian)(qian)，正極板(ban)上(shang)(shang)的(de)硫(liu)酸鉛(qian)(qian)逐漸(jian)生成二氧化鉛(qian)(qian)。當(dang)正負極板(ban)上(shang)(shang)的(de)硫(liu)酸鉛(qian)(qian)完全(quan)生成鉛(qian)(qian)和二氧化鉛(qian)(qian)后，電(dian)池(chi)(chi)(chi)開始發生過充(chong)電(dian)反應(ying)(ying)，產生氫氣(qi)(qi)和氧氣(qi)(qi)(這就是電(dian)池(chi)(chi)(chi)析(xi)氣(qi)(qi))。這樣，在(zai)非密(mi)封電(dian)池(chi)(chi)(chi)中，電(dian)解液中的(de)水將逐漸(jian)減少。在(zai)密(mi)封鉛(qian)(qian)酸蓄電(dian)池(chi)(chi)(chi)中，采用中等充(chong)電(dian)速率(lv)(lv)(lv)時，氫氣(qi)(qi)和氧氣(qi)(qi)能(neng)夠重新化合為(wei)水。過充(chong)電(dian)開始的(de)時間(jian)(電(dian)池(chi)(chi)(chi)內部(bu)的(de)安全(quan)電(dian)壓)與充(chong)電(dian)的(de)速率(lv)(lv)(lv)有(you)關。當(dang)充(chong)電(dian)速率(lv)(lv)(lv)大于(yu)C/5，電(dian)池(chi)(chi)(chi)容量(liang)(liang)恢(hui)復到(dao)額定(ding)容量(liang)(liang)的(de)80%以前，即開始發生過充(chong)電(dian)反應(ying)(ying)。只有(you)充(chong)電(dian)速率(lv)(lv)(lv)小于(yu)C/100，才能(neng)使(shi)電(dian)池(chi)(chi)(chi)在(zai)容量(liang)(liang)恢(hui)復到(dao)100%后，出現過充(chong)電(dian)反應(ying)(ying)。為(wei)了使(shi)電(dian)池(chi)(chi)(chi)容量(liang)(liang)恢(hui)復到(dao)100%，必須允許一定(ding)的(de)過充(chong)電(dian)反應(ying)(ying)。
