蓄(xu)電(dian)池(chi)充(chong)電(dian)機(ji)的(de)(de)種類很多，目前應用最廣的(de)(de)主要(yao)是密封鉛酸(suan)蓄(xu)電(dian)池(chi)和鎳鎘電(dian)池(chi)。這2種蓄(xu)電(dian)池(chi)的(de)(de)充(chong)放電(dian)原理都是一樣的(de)(de)，即都是通過化(hua)學(xue)反應產生正負離子形(xing)成電(dian)流。
蓄電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)機的(de)(de)(de)電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)在(zai)充(chong)(chong)(chong)放電(dian)(dian)的(de)(de)(de)過程中會產(chan)生(sheng)氧(yang)(yang)氣(qi)(qi)(qi)，在(zai)密封(feng)式蓄電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)中，這(zhe)些正極產(chan)生(sheng)的(de)(de)(de)氧(yang)(yang)氣(qi)(qi)(qi)可(ke)以通(tong)過隔膜(mo)和氣(qi)(qi)(qi)室被負(fu)極吸(xi)收(shou)，整(zheng)個(ge)化(hua)學(xue)(xue)反(fan)(fan)應(ying)形(xing)成(cheng)(cheng)一(yi)(yi)(yi)個(ge)循環的(de)(de)(de)反(fan)(fan)應(ying)形(xing)式。就密封(feng)式電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)而(er)言，它的(de)(de)(de)內(nei)(nei)壓有限，因(yin)此負(fu)極的(de)(de)(de)吸(xi)收(shou)速度(du)(du)(du)也是有限的(de)(de)(de)。如果充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)壓過高(gao)(gao)(gao)，正極產(chan)生(sheng)氧(yang)(yang)氣(qi)(qi)(qi)的(de)(de)(de)速度(du)(du)(du)過快(kuai)，負(fu)極的(de)(de)(de)吸(xi)收(shou)速度(du)(du)(du)跟(gen)不(bu)上(shang)氧(yang)(yang)氣(qi)(qi)(qi)的(de)(de)(de)產(chan)生(sheng)速度(du)(du)(du)，長時間之后必然造成(cheng)(cheng)電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)失(shi)水，從(cong)而(er)誘發電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)微(wei)短(duan)路硫酸化(hua)等失(shi)效現象，損害電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)質量，縮短(duan)其使(shi)(shi)用(yong)壽命(ming)。同時高(gao)(gao)(gao)速率充(chong)(chong)(chong)電(dian)(dian)時電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)極化(hua)會造成(cheng)(cheng)電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)內(nei)(nei)部壓力上(shang)升，電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)溫度(du)(du)(du)上(shang)升，電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)內(nei)(nei)阻(zu)升高(gao)(gao)(gao)，這(zhe)不(bu)僅(jin)會縮短(duan)電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)壽命(ming)，而(er)且有可(ke)能(neng)(neng)對(dui)電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)造成(cheng)(cheng)永久性傷害。蓄電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)這(zhe)一(yi)(yi)(yi)化(hua)學(xue)(xue)反(fan)(fan)應(ying)原理(li)是研(yan)究制定快(kuai)速充(chong)(chong)(chong)電(dian)(dian)方法的(de)(de)(de)根本。一(yi)(yi)(yi)方面(mian)，快(kuai)速充(chong)(chong)(chong)電(dian)(dian)要盡量加快(kuai)電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)化(hua)學(xue)(xue)反(fan)(fan)應(ying)，使(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)速度(du)(du)(du)得到(dao)最大的(de)(de)(de)提高(gao)(gao)(gao);另一(yi)(yi)(yi)方面(mian)，又要保證負(fu)極的(de)(de)(de)吸(xi)收(shou)能(neng)(neng)力，使(shi)(shi)其能(neng)(neng)夠跟(gen)得上(shang)正極氧(yang)(yang)氣(qi)(qi)(qi)產(chan)生(sheng)的(de)(de)(de)速度(du)(du)(du)，同時要盡可(ke)能(neng)(neng)消除電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)極化(hua)現象。
