蓄電池充電機最早采用的是變壓器式的充電機，但是由于變壓器式充電機的體(ti)積過于大、笨重、造價低、充(chong)電(dian)(dian)(dian)(dian)(dian)效率低，現(xian)在(zai)基本上很少(shao)采用(yong)。目前使用(yong)比較廣泛的是電(dian)(dian)(dian)(dian)(dian)子(zi)充(chong)電(dian)(dian)(dian)(dian)(dian)器。蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)機輸入交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)壓為220V左右(you)，輸出(chu)端接蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)，其(qi)充(chong)電(dian)(dian)(dian)(dian)(dian)方式(shi)：其(qi)一(yi)，以(yi)大電(dian)(dian)(dian)(dian)(dian)流(liu)脈沖充(chong)電(dian)(dian)(dian)(dian)(dian)間歇(xie)放電(dian)(dian)(dian)(dian)(dian)、補償；其(qi)二，以(yi)恒流(liu)、恒壓浮沖保(bao)持(chi)對被(bei)沖的蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)提供穩(wen)定的充(chong)電(dian)(dian)(dian)(dian)(dian)壓及電(dian)(dian)(dian)(dian)(dian)流(liu)。

充(chong)電(dian)(dian)(dian)機具有(you)輸出短(duan)路(lu)保(bao)護、輸出過壓、過流保(bao)護及過沖保(bao)護功能(neng)，保(bao)證(zheng)蓄電(dian)(dian)(dian)池(chi)使(shi)(shi)用壽命。由于近(jin)些年(nian)來快(kuai)(kuai)速(su)充(chong)電(dian)(dian)(dian)技術的(de)發展，使(shi)(shi)傳統的(de)鉛酸蓄電(dian)(dian)(dian)池(chi)快(kuai)(kuai)速(su)充(chong)電(dian)(dian)(dian)性(xing)能(neng)不(bu)好(hao)的(de)概念(nian)已有(you)了新的(de)改變。實驗證(zheng)明：多數閥控式鉛酸電(dian)(dian)(dian)池(chi)可以(yi)承受快(kuai)(kuai)速(su)充(chong)電(dian)(dian)(dian)，而且(qie)合理(li)的(de)快(kuai)(kuai)速(su)充(chong)電(dian)(dian)(dian)對(dui)延長電(dian)(dian)(dian)池(chi)壽命不(bu)但(dan)無害(hai)而且(qie)有(you)利。
