對電池充電必須配備充電設備——充電器。充電器就是把交流電網電源經過整流濾波后，并經一系列調控后，輸出DC電源，供給動力電池組進行充電，即電池組接受的直流電。充電器分為三類：
a)早期使用最多的充(chong)電器(qi)(qi)是采用可控(kong)(kong)硅作(zuo)整流控(kong)(kong)制元件的工(gong)頻(pin)充(chong)電器(qi)(qi)。必(bi)須(xu)配置一個龐大而笨重的工(gong)頻(pin)變壓(ya)器(qi)(qi)。而且效率(lv)低(di)、功率(lv)因(yin)數低(di)、容易對(dui)電網造成(cheng)污染。
b)高頻開關(guan)電(dian)(dian)源(yuan)充(chong)(chong)(chong)電(dian)(dian)器。它具有體積小(xiao)(xiao)，重量輕，工作可(ke)靠，效率高，功(gong)(gong)率因數(shu)高、不怕電(dian)(dian)網波動(dong)和不造成(cheng)電(dian)(dian)網波動(dong)、既不怕電(dian)(dian)網干(gan)擾又不干(gan)擾電(dian)(dian)網、功(gong)(gong)率可(ke)小(xiao)(xiao)可(ke)大(da)，容易實現智(zhi)能(neng)化(hua)等優點(dian)。特別(bie)適合做小(xiao)(xiao)功(gong)(gong)率到大(da)功(gong)(gong)率、特大(da)功(gong)(gong)率的(de)高頻開關(guan)電(dian)(dian)源(yuan)充(chong)(chong)(chong)電(dian)(dian)器。可(ke)以(yi)通(tong)過(guo)模塊(kuai)(kuai)的(de)串聯(lian)，做成(cheng)高壓(ya)充(chong)(chong)(chong)電(dian)(dian)器；也可(ke)以(yi)通(tong)過(guo)模塊(kuai)(kuai)的(de)并聯(lian)，做成(cheng)大(da)電(dian)(dian)流(liu)充(chong)(chong)(chong)電(dian)(dian)器；還可(ke)以(yi)通(tong)過(guo)模塊(kuai)(kuai)的(de)串聯(lian)和并聯(lian)，做成(cheng)高電(dian)(dian)壓(ya)、大(da)電(dian)(dian)流(liu)的(de)大(da)功(gong)(gong)率充(chong)(chong)(chong)電(dian)(dian)器。該開關(guan)電(dian)(dian)源(yuan)充(chong)(chong)(chong)電(dian)(dian)器還具有根據電(dian)(dian)池(chi)(chi)管理系統(BMS)的(de)信息，自動(dong)調節充(chong)(chong)(chong)電(dian)(dian)參數(shu)和自動(dong)保護電(dian)(dian)池(chi)(chi)的(de)功(gong)(gong)能(neng)。
c)種脈(mo)沖充(chong)電(dian)器，結構比較復朵，技術難度較大(da)。脈(mo)沖充(chong)電(dian)可(ke)以減少電(dian)池在充(chong)電(dian)時產生的極化現象(xiang)，從而(er)提高電(dian)池的充(chong)電(dian)效(xiao)率(lv)，減少充(chong)電(dian)時間(jian)，實(shi)現快速充(chong)電(dian)。
以上說明(ming)，電能(neng)(neng)變成化(hua)學能(neng)(neng)是一(yi)個十分復雜(za)的過程，必須有充(chong)電器(qi)和BMS協同工(gong)作(zuo)，才能(neng)(neng)完成這一(yi)工(gong)作(zuo)。
