使用(yong)小區充(chong)電(dian)樁給(gei)電(dian)動車充(chong)電(dian)通常要完成兩個(ge)*基本的(de)任務，首先(xian)是盡可(ke)能(neng)快(kuai)地使電(dian)池恢復(fu)額定容(rong)(rong)量，另一是使用(yong)小電(dian)流充(chong)電(dian)，電(dian)動車充(chong)電(dian)樁補(bu)充(chong)電(dian)池因(yin)自放電(dian)而損失的(de)能(neng)量，以(yi)維持電(dian)池的(de)額定容(rong)(rong)量。
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車(che)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)樁(zhuang)在(zai)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)(guo)(guo)程中(zhong)，鉛(qian)酸(suan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)負極(ji)板(ban)上的(de)(de)(de)硫(liu)(liu)酸(suan)鉛(qian)逐(zhu)(zhu)漸(jian)析(xi)出鉛(qian)，正(zheng)極(ji)板(ban)上的(de)(de)(de)硫(liu)(liu)酸(suan)鉛(qian)逐(zhu)(zhu)漸(jian)生(sheng)成(cheng)二(er)氧化(hua)鉛(qian)。當正(zheng)負極(ji)板(ban)上的(de)(de)(de)硫(liu)(liu)酸(suan)鉛(qian)完全(quan)生(sheng)成(cheng)鉛(qian)和(he)二(er)氧化(hua)鉛(qian)后(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)開(kai)始發(fa)生(sheng)過(guo)(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)反(fan)應(ying)，產(chan)生(sheng)氫氣(qi)(qi)(qi)和(he)氧氣(qi)(qi)(qi)(這就是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)析(xi)氣(qi)(qi)(qi))。這樣，在(zai)非密封(feng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)中(zhong)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液(ye)中(zhong)的(de)(de)(de)水將逐(zhu)(zhu)漸(jian)減少。在(zai)密封(feng)鉛(qian)酸(suan)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)中(zhong)，采用中(zhong)等充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)速率(lv)(lv)時(shi)，氫氣(qi)(qi)(qi)和(he)氧氣(qi)(qi)(qi)能(neng)夠重新化(hua)合為(wei)水。過(guo)(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)開(kai)始的(de)(de)(de)時(shi)間(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)內(nei)部的(de)(de)(de)安全(quan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓)與充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)速率(lv)(lv)有關。當充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)速率(lv)(lv)大于C/5，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)量(liang)(liang)恢復(fu)到額定(ding)容(rong)(rong)量(liang)(liang)的(de)(de)(de)80%以前，即開(kai)始發(fa)生(sheng)過(guo)(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)反(fan)應(ying)。只有充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)速率(lv)(lv)小(xiao)于C/100，才能(neng)使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在(zai)容(rong)(rong)量(liang)(liang)恢復(fu)到100%后(hou)，出現過(guo)(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)反(fan)應(ying)。為(wei)了使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)(rong)量(liang)(liang)恢復(fu)到100%，必須允(yun)許一定(ding)的(de)(de)(de)過(guo)(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)反(fan)應(ying)。
為(wei)方(fang)(fang)(fang)便(bian)物業(ye)對電(dian)(dian)(dian)動(dong)車(che)(che)充(chong)(chong)(chong)電(dian)(dian)(dian)管理，電(dian)(dian)(dian)動(dong)車(che)(che)主又得以(yi)方(fang)(fang)(fang)便(bian)及時的充(chong)(chong)(chong)電(dian)(dian)(dian)，智(zhi)能(neng)小區電(dian)(dian)(dian)動(dong)車(che)(che)充(chong)(chong)(chong)電(dian)(dian)(dian)樁被研發(fa)，并(bing)且迅速(su)發(fa)展(zhan)。有了(le)投幣小區智(zhi)能(neng)充(chong)(chong)(chong)電(dian)(dian)(dian)樁，再也不用私自牽拉(la)電(dian)(dian)(dian)線(xian)，物業(ye)方(fang)(fang)(fang)的管理也方(fang)(fang)(fang)便(bian)輕松多了(le)。在給(gei)電(dian)(dian)(dian)動(dong)車(che)(che)充(chong)(chong)(chong)電(dian)(dian)(dian)時只要插接(jie)上電(dian)(dian)(dian)動(dong)車(che)(che)自帶的充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)就可實(shi)現充(chong)(chong)(chong)電(dian)(dian)(dian)，而普通(tong)的220V電(dian)(dian)(dian)源(yuan)給(gei)電(dian)(dian)(dian)動(dong)車(che)(che)充(chong)(chong)(chong)電(dian)(dian)(dian)，這樣正常(chang)的充(chong)(chong)(chong)電(dian)(dian)(dian)不容易(yi)損傷電(dian)(dian)(dian)瓶，也解決(jue)了(le)車(che)(che)主的憂慮(lv)。
電(dian)(dian)(dian)動車充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)過(guo)充(chong)(chong)電(dian)(dian)(dian)反應發(fa)生(sheng)后，單格電(dian)(dian)(dian)池(chi)的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)迅速上(shang)(shang)升(sheng)，達(da)到(dao)一定數值后，上(shang)(shang)升(sheng)速率減小，然后電(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)壓(ya)(ya)(ya)開始緩慢(man)下降。由此可知(zhi)，電(dian)(dian)(dian)池(chi)充(chong)(chong)足電(dian)(dian)(dian)后，維持(chi)電(dian)(dian)(dian)池(chi)容量的(de)(de)*佳方法就是在電(dian)(dian)(dian)池(chi)組兩端加入(ru)恒定的(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)。浮(fu)(fu)充(chong)(chong)電(dian)(dian)(dian)壓(ya)(ya)(ya)下，充(chong)(chong)入(ru)的(de)(de)電(dian)(dian)(dian)流應能(neng)補充(chong)(chong)電(dian)(dian)(dian)池(chi)因自放電(dian)(dian)(dian)而失去的(de)(de)能(neng)量。浮(fu)(fu)充(chong)(chong)電(dian)(dian)(dian)壓(ya)(ya)(ya)不能(neng)過(guo)高(gao)，以(yi)免因嚴重的(de)(de)過(guo)充(chong)(chong)電(dian)(dian)(dian)而縮短電(dian)(dian)(dian)池(chi)壽(shou)命。小區(qu)電(dian)(dian)(dian)動車智能(neng)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)采用適當的(de)(de)浮(fu)(fu)充(chong)(chong)電(dian)(dian)(dian)壓(ya)(ya)(ya)，密封鉛酸蓄電(dian)(dian)(dian)池(chi)的(de)(de)壽(shou)命可達(da)10年以(yi)上(shang)(shang)。
實(shi)踐證明，實(shi)際的(de)浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)與規定的(de)浮充(chong)(chong)電(dian)(dian)(dian)(dian)壓(ya)相差5%時(shi)，免維護蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)壽命將縮短(duan)一半(ban)。鉛酸電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)壓(ya)具有(you)負溫(wen)度(du)(du)(du)(du)系數(shu)，其單(dan)格值(zhi)為-4mV/℃。在(zai)環境溫(wen)度(du)(du)(du)(du)為25℃時(shi)工作很理想的(de)普通(無溫(wen)度(du)(du)(du)(du)補償)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)，當(dang)環境溫(wen)度(du)(du)(du)(du)降到0℃時(shi)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)就不能充(chong)(chong)足(zu)電(dian)(dian)(dian)(dian)，當(dang)環境溫(wen)度(du)(du)(du)(du)上升到50℃時(shi)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)將因嚴重的(de)過充(chong)(chong)電(dian)(dian)(dian)(dian)而(er)縮短(duan)壽命。因此，為了保證在(zai)很寬的(de)溫(wen)度(du)(du)(du)(du)范(fan)圍內，都能使電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)剛好充(chong)(chong)足(zu)電(dian)(dian)(dian)(dian)，智能電(dian)(dian)(dian)(dian)動車充(chong)(chong)電(dian)(dian)(dian)(dian)樁充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的(de)各種轉換(huan)電(dian)(dian)(dian)(dian)壓(ya)必須隨電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)的(de)溫(wen)度(du)(du)(du)(du)系數(shu)而(er)變。
