充電器:是(shi)一種通(tong)過向充(chong)電(dian)池(chi)通(tong)入電(dian)流而(er)為電(dian)池(chi)充(chong)入能量(liang)的(de)裝(zhuang)置(zhi)。是(shi)一種將交流電(dian)轉換為低(di)壓直(zhi)流電(dian)的(de)設備。

脈沖式充電器:一種對(dui)可(ke)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)按(an)照(zhao)脈沖方式(shi)(shi)(shi)進(jin)行充(chong)電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)器(qi)裝置.它是按(an)照(zhao)充(chong)電(dian)(dian)(dian)(dian)方式(shi)(shi)(shi)來區別的,有別于其它的充(chong)電(dian)(dian)(dian)(dian)方式(shi)(shi)(shi),例(li)如.手(shou)搖(yao)方式(shi)(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)器(qi),恒壓(ya)充(chong)電(dian)(dian)(dian)(dian)器(qi)以及(ji)混合方法的三(san)段(duan)(duan)式(shi)(shi)(shi)充(chong)電(dian)(dian)(dian)(dian)器(qi)(第(di)一個(ge)階(jie)(jie)段(duan)(duan)叫(jiao)充(chong)電(dian)(dian)(dian)(dian)限(xian)流階(jie)(jie)段(duan)(duan)，第(di)二個(ge)階(jie)(jie)段(duan)(duan)叫(jiao)高恒壓(ya)階(jie)(jie)段(duan)(duan)，第(di)三(san)個(ge)階(jie)(jie)段(duan)(duan)叫(jiao)小(xiao)電(dian)(dian)(dian)(dian)流低(di)恒壓(ya)階(jie)(jie)段(duan)(duan)).

　　1967年(nian)美國人(ren)麥斯研究公(gong)布.用(yong)大于1C(C是電(dian)(dian)池(chi)(chi)容量)率(lv)脈沖(chong)電(dian)(dian)流充電(dian)(dian)，充電(dian)(dian)間歇時(shi)(shi)對電(dian)(dian)池(chi)(chi)放(fang)電(dian)(dian)。放(fang)電(dian)(dian)有利于消除極化、降低電(dian)(dian)解(jie)液溫度、提高極板接(jie)受(shou)電(dian)(dian)荷的(de)能力(li)。可(ke)以(yi)在加速電(dian)(dian)池(chi)(chi)充電(dian)(dian)過程同時(shi)(shi)保證獲得足量的(de)充電(dian)(dian)電(dian)(dian)能.
