對電池充電實際上“電”能轉換成“化學”能過程

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(yong)最多的充電(dian)器(qi)是采用(yong)可控硅(gui)作(zuo)整流控制(zhi)元件的工頻(pin)充電(dian)器(qi)。必須配置一個龐大(da)而笨重的工頻(pin)變壓器(qi)。而且效率低、功率因數低、容(rong)易對電(dian)網(wang)造成污染。
b)高頻開關電(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)。它(ta)具有體積小(xiao)，重量(liang)輕，工作可(ke)(ke)靠，效率(lv)高，功率(lv)因數(shu)高、不怕電(dian)(dian)(dian)網(wang)波動(dong)(dong)和不造成(cheng)(cheng)電(dian)(dian)(dian)網(wang)波動(dong)(dong)、既不怕電(dian)(dian)(dian)網(wang)干擾(rao)又不干擾(rao)電(dian)(dian)(dian)網(wang)、功率(lv)可(ke)(ke)小(xiao)可(ke)(ke)大(da)，容易實現智(zhi)能化等優點(dian)。特(te)(te)別適合做(zuo)小(xiao)功率(lv)到(dao)大(da)功率(lv)、特(te)(te)大(da)功率(lv)的(de)(de)高頻開關電(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)。可(ke)(ke)以通過模(mo)塊的(de)(de)串聯(lian)，做(zuo)成(cheng)(cheng)高壓充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)；也可(ke)(ke)以通過模(mo)塊的(de)(de)并聯(lian)，做(zuo)成(cheng)(cheng)大(da)電(dian)(dian)(dian)流(liu)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)；還可(ke)(ke)以通過模(mo)塊的(de)(de)串聯(lian)和并聯(lian)，做(zuo)成(cheng)(cheng)高電(dian)(dian)(dian)壓、大(da)電(dian)(dian)(dian)流(liu)的(de)(de)大(da)功率(lv)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)。該開關電(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)還具有根據電(dian)(dian)(dian)池管(guan)理系(xi)統(BMS)的(de)(de)信息，自動(dong)(dong)調節充(chong)(chong)電(dian)(dian)(dian)參數(shu)和自動(dong)(dong)保護電(dian)(dian)(dian)池的(de)(de)功能。
c)種脈(mo)沖充(chong)(chong)(chong)電(dian)(dian)器，結構(gou)比較復朵，技術難度較大。脈(mo)沖充(chong)(chong)(chong)電(dian)(dian)可以減少(shao)電(dian)(dian)池(chi)在充(chong)(chong)(chong)電(dian)(dian)時產生的極化現(xian)象，從而提高電(dian)(dian)池(chi)的充(chong)(chong)(chong)電(dian)(dian)效(xiao)率，減少(shao)充(chong)(chong)(chong)電(dian)(dian)時間(jian)，實現(xian)快速充(chong)(chong)(chong)電(dian)(dian)。
以上說(shuo)明，電能變成(cheng)化學(xue)能是一個十分復(fu)雜的過程，必須(xu)有充電器和(he)BMS協同工作(zuo)，才能完成(cheng)這一工作(zuo)。
