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(de)充電器是采用可控硅作整流(liu)控制元(yuan)件的(de)工(gong)頻充電器。必(bi)須配置一個龐大而笨重的(de)工(gong)頻變(bian)壓器。而且(qie)效率(lv)低(di)、功率(lv)因(yin)數低(di)、容易(yi)對電網造(zao)成污(wu)染(ran)。
b)高頻開關(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。它具(ju)有體積(ji)小(xiao),重量輕,工作(zuo)可靠,效率(lv)高,功(gong)率(lv)因數高、不怕電(dian)(dian)(dian)(dian)(dian)網(wang)波動(dong)和不造成(cheng)電(dian)(dian)(dian)(dian)(dian)網(wang)波動(dong)、既不怕電(dian)(dian)(dian)(dian)(dian)網(wang)干(gan)(gan)擾又不干(gan)(gan)擾電(dian)(dian)(dian)(dian)(dian)網(wang)、功(gong)率(lv)可小(xiao)可大,容易實現智能化等優點。特(te)別適合(he)做小(xiao)功(gong)率(lv)到(dao)大功(gong)率(lv)、特(te)大功(gong)率(lv)的高頻開關(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。可以通(tong)(tong)過(guo)(guo)模(mo)(mo)塊的串聯(lian),做成(cheng)高壓(ya)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi);也(ye)可以通(tong)(tong)過(guo)(guo)模(mo)(mo)塊的并聯(lian),做成(cheng)大電(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi);還(huan)可以通(tong)(tong)過(guo)(guo)模(mo)(mo)塊的串聯(lian)和并聯(lian),做成(cheng)高電(dian)(dian)(dian)(dian)(dian)壓(ya)、大電(dian)(dian)(dian)(dian)(dian)流的大功(gong)率(lv)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。該開關(guan)電(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)還(huan)具(ju)有根據(ju)電(dian)(dian)(dian)(dian)(dian)池(chi)管理系統(BMS)的信息(xi),自動(dong)調(diao)節(jie)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)參(can)數和自動(dong)保護電(dian)(dian)(dian)(dian)(dian)池(chi)的功(gong)能。
c)種脈沖(chong)充(chong)電(dian)(dian)(dian)器,結構比較復朵(duo),技術難度較大(da)。脈沖(chong)充(chong)電(dian)(dian)(dian)可以減少電(dian)(dian)(dian)池在充(chong)電(dian)(dian)(dian)時(shi)產生的極化(hua)現(xian)象,從(cong)而提(ti)高電(dian)(dian)(dian)池的充(chong)電(dian)(dian)(dian)效率(lv),減少充(chong)電(dian)(dian)(dian)時(shi)間,實(shi)現(xian)快速(su)充(chong)電(dian)(dian)(dian)。
以上說(shuo)明,電能(neng)變成化學(xue)能(neng)是一(yi)個十分(fen)復雜(za)的過程,必須(xu)有充電器(qi)和BMS協同工(gong)(gong)作,才能(neng)完成這(zhe)一(yi)工(gong)(gong)作。
