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——茄子視頻APP官網: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)(de)充電(dian)器是采用可控硅作整流控制元件的(de)(de)工頻充電(dian)器。必須配置(zhi)一(yi)個龐大而笨重的(de)(de)工頻變壓器。而且效率(lv)低(di)、功率(lv)因(yin)數低(di)、容易對(dui)電(dian)網造(zao)成污染。
b)高(gao)(gao)頻開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)源充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。它具有體(ti)積小,重量(liang)輕,工(gong)作可(ke)(ke)靠,效(xiao)率(lv)(lv)(lv)(lv)高(gao)(gao),功率(lv)(lv)(lv)(lv)因數高(gao)(gao)、不(bu)怕(pa)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)波動(dong)和不(bu)造成電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)波動(dong)、既不(bu)怕(pa)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)干擾又不(bu)干擾電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)、功率(lv)(lv)(lv)(lv)可(ke)(ke)小可(ke)(ke)大,容易(yi)實現智能化(hua)等優點。特(te)別(bie)適合做(zuo)小功率(lv)(lv)(lv)(lv)到大功率(lv)(lv)(lv)(lv)、特(te)大功率(lv)(lv)(lv)(lv)的(de)(de)(de)高(gao)(gao)頻開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)源充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。可(ke)(ke)以通過(guo)模(mo)塊(kuai)的(de)(de)(de)串(chuan)聯(lian),做(zuo)成高(gao)(gao)壓充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi);也可(ke)(ke)以通過(guo)模(mo)塊(kuai)的(de)(de)(de)并聯(lian),做(zuo)成大電(dian)(dian)(dian)(dian)(dian)(dian)流充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi);還可(ke)(ke)以通過(guo)模(mo)塊(kuai)的(de)(de)(de)串(chuan)聯(lian)和并聯(lian),做(zuo)成高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)(dian)壓、大電(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)大功率(lv)(lv)(lv)(lv)充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。該(gai)開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)源充電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)還具有根據電(dian)(dian)(dian)(dian)(dian)(dian)池管理系統(BMS)的(de)(de)(de)信息,自動(dong)調(diao)節充電(dian)(dian)(dian)(dian)(dian)(dian)參數和自動(dong)保護電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)功能。
c)種脈(mo)(mo)沖充(chong)(chong)電(dian)器,結構比較復朵(duo),技(ji)術難度較大(da)。脈(mo)(mo)沖充(chong)(chong)電(dian)可以減(jian)少(shao)電(dian)池在充(chong)(chong)電(dian)時(shi)產(chan)生(sheng)的極化現(xian)象,從而提(ti)高電(dian)池的充(chong)(chong)電(dian)效率(lv),減(jian)少(shao)充(chong)(chong)電(dian)時(shi)間,實現(xian)快速充(chong)(chong)電(dian)。
以上說明,電能變成(cheng)化(hua)學能是一(yi)個(ge)十(shi)分復雜的過(guo)程(cheng),必須有(you)充電器(qi)和BMS協同工作,才能完成(cheng)這(zhe)一(yi)工作。
