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)早期使用最多的充(chong)電(dian)器(qi)是采(cai)用可控(kong)硅(gui)作整(zheng)流控(kong)制(zhi)元件的工頻充(chong)電(dian)器(qi)。必須配置一(yi)個龐(pang)大而笨重的工頻變壓(ya)器(qi)。而且效率低、功率因(yin)數(shu)低、容(rong)易對電(dian)網造(zao)成污染。
b)高(gao)頻開關電(dian)源(yuan)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)。它具有體積小，重量輕，工作可(ke)(ke)(ke)靠，效率(lv)高(gao)，功率(lv)因數高(gao)、不怕電(dian)網(wang)波動(dong)和(he)(he)不造成電(dian)網(wang)波動(dong)、既不怕電(dian)網(wang)干擾(rao)又不干擾(rao)電(dian)網(wang)、功率(lv)可(ke)(ke)(ke)小可(ke)(ke)(ke)大(da)，容易實現智能(neng)化(hua)等優(you)點。特(te)別適(shi)合做小功率(lv)到(dao)大(da)功率(lv)、特(te)大(da)功率(lv)的高(gao)頻開關電(dian)源(yuan)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)。可(ke)(ke)(ke)以通過模塊(kuai)的串(chuan)聯，做成高(gao)壓充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)；也可(ke)(ke)(ke)以通過模塊(kuai)的并聯，做成大(da)電(dian)流(liu)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)；還可(ke)(ke)(ke)以通過模塊(kuai)的串(chuan)聯和(he)(he)并聯，做成高(gao)電(dian)壓、大(da)電(dian)流(liu)的大(da)功率(lv)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)。該開關電(dian)源(yuan)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)器(qi)(qi)還具有根據電(dian)池管理(li)系統(tong)(BMS)的信(xin)息(xi)，自動(dong)調節充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)參數和(he)(he)自動(dong)保護(hu)電(dian)池的功能(neng)。
c)種(zhong)脈沖(chong)充(chong)電(dian)(dian)器，結構比較(jiao)復(fu)朵，技術難(nan)度(du)較(jiao)大。脈沖(chong)充(chong)電(dian)(dian)可以減少電(dian)(dian)池在充(chong)電(dian)(dian)時(shi)產生(sheng)的極化(hua)現象，從(cong)而提高電(dian)(dian)池的充(chong)電(dian)(dian)效率，減少充(chong)電(dian)(dian)時(shi)間，實(shi)現快(kuai)速充(chong)電(dian)(dian)。
以上說明，電能變成化(hua)學能是一個十分復雜(za)的過程，必(bi)須有充電器和BMS協同(tong)工作，才能完成這一工作。
