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(zui)多的充(chong)電(dian)器(qi)是采用可控硅作整(zheng)流(liu)控制元件(jian)的工頻(pin)(pin)充(chong)電(dian)器(qi)。必(bi)須配置(zhi)一個(ge)龐(pang)大(da)而笨重的工頻(pin)(pin)變壓器(qi)。而且效率低(di)、功(gong)率因數低(di)、容易對電(dian)網造成污染。
b)高(gao)(gao)頻(pin)開(kai)關電(dian)(dian)源充(chong)(chong)(chong)電(dian)(dian)器。它具有體積小(xiao)(xiao)，重量輕，工作(zuo)可(ke)靠(kao)，效率(lv)高(gao)(gao)，功(gong)率(lv)因數高(gao)(gao)、不(bu)怕(pa)(pa)電(dian)(dian)網波動(dong)和不(bu)造成電(dian)(dian)網波動(dong)、既不(bu)怕(pa)(pa)電(dian)(dian)網干擾又不(bu)干擾電(dian)(dian)網、功(gong)率(lv)可(ke)小(xiao)(xiao)可(ke)大(da)，容(rong)易(yi)實現智(zhi)能(neng)化等優點。特(te)別(bie)適合做(zuo)(zuo)小(xiao)(xiao)功(gong)率(lv)到大(da)功(gong)率(lv)、特(te)大(da)功(gong)率(lv)的(de)高(gao)(gao)頻(pin)開(kai)關電(dian)(dian)源充(chong)(chong)(chong)電(dian)(dian)器。可(ke)以(yi)通(tong)過(guo)模(mo)(mo)(mo)塊(kuai)(kuai)的(de)串聯(lian)(lian)，做(zuo)(zuo)成高(gao)(gao)壓充(chong)(chong)(chong)電(dian)(dian)器；也可(ke)以(yi)通(tong)過(guo)模(mo)(mo)(mo)塊(kuai)(kuai)的(de)并(bing)聯(lian)(lian)，做(zuo)(zuo)成大(da)電(dian)(dian)流充(chong)(chong)(chong)電(dian)(dian)器；還(huan)可(ke)以(yi)通(tong)過(guo)模(mo)(mo)(mo)塊(kuai)(kuai)的(de)串聯(lian)(lian)和并(bing)聯(lian)(lian)，做(zuo)(zuo)成高(gao)(gao)電(dian)(dian)壓、大(da)電(dian)(dian)流的(de)大(da)功(gong)率(lv)充(chong)(chong)(chong)電(dian)(dian)器。該開(kai)關電(dian)(dian)源充(chong)(chong)(chong)電(dian)(dian)器還(huan)具有根據電(dian)(dian)池管理系統(tong)(BMS)的(de)信(xin)息，自動(dong)調節充(chong)(chong)(chong)電(dian)(dian)參(can)數和自動(dong)保護電(dian)(dian)池的(de)功(gong)能(neng)。
c)種脈沖充(chong)電(dian)器，結構比較復朵，技(ji)術難度較大。脈沖充(chong)電(dian)可以減少電(dian)池在充(chong)電(dian)時產生的(de)極化現(xian)象，從而提高(gao)電(dian)池的(de)充(chong)電(dian)效率(lv)，減少充(chong)電(dian)時間，實現(xian)快速充(chong)電(dian)。
以上(shang)說(shuo)明，電(dian)能變(bian)成化學能是一(yi)個十分復雜的過程，必須有充(chong)電(dian)器和BMS協同工作，才能完成這一(yi)工作。
