充電器:是一種通過向充(chong)電(dian)池通入電(dian)流(liu)而為電(dian)池充(chong)入能量的(de)裝(zhuang)置。是一種將交(jiao)流(liu)電(dian)轉換為低壓直(zhi)流(liu)電(dian)的(de)設備。

脈沖式充電器:一種(zhong)對(dui)可充(chong)電(dian)電(dian)池按照(zhao)脈沖方式進行充(chong)電(dian)的電(dian)器裝(zhuang)置.它是按照(zhao)充(chong)電(dian)方式來區別的,有別于其它的充(chong)電(dian)方式,例如.手搖方式充(chong)電(dian)器,恒(heng)壓(ya)充(chong)電(dian)器以及混合方法的三(san)(san)段式充(chong)電(dian)器(第一個階(jie)(jie)(jie)段叫充(chong)電(dian)限(xian)流階(jie)(jie)(jie)段，第二個階(jie)(jie)(jie)段叫高恒(heng)壓(ya)階(jie)(jie)(jie)段，第三(san)(san)個階(jie)(jie)(jie)段叫小電(dian)流低恒(heng)壓(ya)階(jie)(jie)(jie)段).

　　1967年美國人麥斯(si)研究公布(bu).用(yong)大于1C(C是電(dian)(dian)(dian)(dian)池容量)率脈沖電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)間(jian)歇時對電(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)。放電(dian)(dian)(dian)(dian)有利(li)于消除極化、降(jiang)低(di)電(dian)(dian)(dian)(dian)解(jie)液溫度、提高極板接受電(dian)(dian)(dian)(dian)荷的能力。可以(yi)在加速(su)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)過程同時保證獲得足量的充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)能.
