蓄(xu)(xu)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)機的種類很多(duo),目(mu)前應用最(zui)廣的主要是(shi)密封鉛酸蓄(xu)(xu)電(dian)(dian)(dian)池(chi)和鎳鎘電(dian)(dian)(dian)池(chi)。這2種蓄(xu)(xu)電(dian)(dian)(dian)池(chi)的充(chong)放電(dian)(dian)(dian)原理都(dou)是(shi)一樣(yang)的,即都(dou)是(shi)通(tong)過化學反應產生正負離(li)子形(xing)成(cheng)電(dian)(dian)(dian)流。
蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)機的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)在(zai)(zai)充(chong)放電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)過(guo)(guo)(guo)程中會產(chan)生(sheng)氧氣,在(zai)(zai)密封式蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)中,這些(xie)正(zheng)(zheng)極(ji)產(chan)生(sheng)的(de)(de)(de)(de)(de)氧氣可以通過(guo)(guo)(guo)隔膜(mo)和氣室被負(fu)(fu)極(ji)吸收(shou),整個化學(xue)反應(ying)形(xing)成(cheng)一(yi)個循環的(de)(de)(de)(de)(de)反應(ying)形(xing)式。就密封式電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)而(er)言,它的(de)(de)(de)(de)(de)內壓有(you)限,因(yin)此負(fu)(fu)極(ji)的(de)(de)(de)(de)(de)吸收(shou)速(su)度(du)(du)(du)也是有(you)限的(de)(de)(de)(de)(de)。如果充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓過(guo)(guo)(guo)高,正(zheng)(zheng)極(ji)產(chan)生(sheng)氧氣的(de)(de)(de)(de)(de)速(su)度(du)(du)(du)過(guo)(guo)(guo)快,負(fu)(fu)極(ji)的(de)(de)(de)(de)(de)吸收(shou)速(su)度(du)(du)(du)跟不(bu)上(shang)氧氣的(de)(de)(de)(de)(de)產(chan)生(sheng)速(su)度(du)(du)(du),長時(shi)(shi)間之后必然造成(cheng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)失水(shui),從(cong)而(er)誘發電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)微短路硫酸化等失效(xiao)現象(xiang),損害(hai)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)質量,縮(suo)短其(qi)使(shi)(shi)用壽(shou)(shou)命。同(tong)時(shi)(shi)高速(su)率充(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)極(ji)化會造成(cheng)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內部壓力上(shang)升(sheng),電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)溫度(du)(du)(du)上(shang)升(sheng),電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)內阻(zu)升(sheng)高,這不(bu)僅會縮(suo)短電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)壽(shou)(shou)命,而(er)且(qie)有(you)可能(neng)(neng)對電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)造成(cheng)永(yong)久性傷害(hai)。蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)這一(yi)化學(xue)反應(ying)原理是研究制(zhi)定(ding)快速(su)充(chong)電(dian)(dian)(dian)(dian)方(fang)法(fa)的(de)(de)(de)(de)(de)根(gen)本。一(yi)方(fang)面,快速(su)充(chong)電(dian)(dian)(dian)(dian)要(yao)盡量加快電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)化學(xue)反應(ying),使(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)速(su)度(du)(du)(du)得(de)到最大(da)的(de)(de)(de)(de)(de)提高;另一(yi)方(fang)面,又要(yao)保證負(fu)(fu)極(ji)的(de)(de)(de)(de)(de)吸收(shou)能(neng)(neng)力,使(shi)(shi)其(qi)能(neng)(neng)夠跟得(de)上(shang)正(zheng)(zheng)極(ji)氧氣產(chan)生(sheng)的(de)(de)(de)(de)(de)速(su)度(du)(du)(du),同(tong)時(shi)(shi)要(yao)盡可能(neng)(neng)消除電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)(de)極(ji)化現象(xiang)。
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(shang)海施能電器(qi)設(she)備(bei)有限公(gong)司始建于(yu)1984年,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。
