蓄(xu)電池(chi)充(chong)電機的(de)種(zhong)類很多,目前應用最廣的(de)主要是(shi)密封鉛酸蓄(xu)電池(chi)和(he)鎳鎘電池(chi)。這2種(zhong)蓄(xu)電池(chi)的(de)充(chong)放電原理都是(shi)一樣的(de),即都是(shi)通過(guo)化學反(fan)應產生正負(fu)離子(zi)形(xing)成電流。
蓄電(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)機的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)在(zai)充(chong)(chong)(chong)放電(dian)(dian)(dian)的(de)(de)(de)過程中會(hui)產(chan)生(sheng)(sheng)(sheng)氧(yang)(yang)氣,在(zai)密封式蓄電(dian)(dian)(dian)池(chi)(chi)中,這(zhe)些正極(ji)產(chan)生(sheng)(sheng)(sheng)的(de)(de)(de)氧(yang)(yang)氣可(ke)以通過隔膜和氣室被負極(ji)吸(xi)收,整個化(hua)(hua)學反(fan)應形(xing)成(cheng)一個循環的(de)(de)(de)反(fan)應形(xing)式。就密封式電(dian)(dian)(dian)池(chi)(chi)而(er)言,它(ta)的(de)(de)(de)內(nei)壓(ya)有(you)(you)限,因此負極(ji)的(de)(de)(de)吸(xi)收速(su)度(du)也是(shi)有(you)(you)限的(de)(de)(de)。如果充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)過高,正極(ji)產(chan)生(sheng)(sheng)(sheng)氧(yang)(yang)氣的(de)(de)(de)速(su)度(du)過快(kuai),負極(ji)的(de)(de)(de)吸(xi)收速(su)度(du)跟不上(shang)氧(yang)(yang)氣的(de)(de)(de)產(chan)生(sheng)(sheng)(sheng)速(su)度(du),長時(shi)(shi)間之后(hou)必然造(zao)(zao)成(cheng)電(dian)(dian)(dian)池(chi)(chi)失水(shui),從而(er)誘(you)發電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)微短路硫酸化(hua)(hua)等失效(xiao)現象,損害(hai)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)質量,縮短其使用(yong)壽命。同時(shi)(shi)高速(su)率充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)極(ji)化(hua)(hua)會(hui)造(zao)(zao)成(cheng)電(dian)(dian)(dian)池(chi)(chi)內(nei)部壓(ya)力(li)上(shang)升,電(dian)(dian)(dian)池(chi)(chi)溫度(du)上(shang)升,電(dian)(dian)(dian)池(chi)(chi)內(nei)阻升高,這(zhe)不僅會(hui)縮短電(dian)(dian)(dian)池(chi)(chi)壽命,而(er)且(qie)有(you)(you)可(ke)能(neng)對電(dian)(dian)(dian)池(chi)(chi)造(zao)(zao)成(cheng)永久性傷害(hai)。蓄電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)這(zhe)一化(hua)(hua)學反(fan)應原(yuan)理是(shi)研究制(zhi)定快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)方法的(de)(de)(de)根本(ben)。一方面,快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)要(yao)盡量加快(kuai)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)化(hua)(hua)學反(fan)應,使充(chong)(chong)(chong)電(dian)(dian)(dian)速(su)度(du)得到最(zui)大的(de)(de)(de)提(ti)高;另一方面,又要(yao)保證負極(ji)的(de)(de)(de)吸(xi)收能(neng)力(li),使其能(neng)夠跟得上(shang)正極(ji)氧(yang)(yang)氣產(chan)生(sheng)(sheng)(sheng)的(de)(de)(de)速(su)度(du),同時(shi)(shi)要(yao)盡可(ke)能(neng)消除電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)極(ji)化(hua)(hua)現象。
提高蓄電池充電機速度有2種方式,一是改進蓄電池的結構以降低其內阻和提高反應離子的擴散速度,二是改進蓄電池的充電方法。本文中對充電方法作了重點論述。上海施能電器設備有限公司始建于1984年(nian),上海市高新技術企業,中國工業車輛優秀配套供應商,上海電器行業名優產品,主要生產工頻系列充電機,高頻系列充電機,鋰電池充電機系列放電機系列充放電機等電器產品。
