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)早期使用最多的充電(dian)(dian)器是采用可控(kong)硅(gui)作整流控(kong)制(zhi)元件(jian)的工頻充電(dian)(dian)器。必(bi)須配置一個龐大而笨(ben)重的工頻變壓器。而且效率(lv)低、功率(lv)因數(shu)低、容易對電(dian)(dian)網(wang)造(zao)成污(wu)染(ran)。
b)高(gao)(gao)頻開關電(dian)(dian)(dian)源(yuan)(yuan)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)。它(ta)具有(you)體(ti)積小(xiao),重量輕,工作可(ke)靠,效率(lv)(lv)(lv)高(gao)(gao),功率(lv)(lv)(lv)因(yin)數高(gao)(gao)、不(bu)怕電(dian)(dian)(dian)網(wang)波動(dong)和不(bu)造(zao)成(cheng)電(dian)(dian)(dian)網(wang)波動(dong)、既不(bu)怕電(dian)(dian)(dian)網(wang)干擾又不(bu)干擾電(dian)(dian)(dian)網(wang)、功率(lv)(lv)(lv)可(ke)小(xiao)可(ke)大,容易實現智能化等(deng)優點。特別(bie)適合做小(xiao)功率(lv)(lv)(lv)到大功率(lv)(lv)(lv)、特大功率(lv)(lv)(lv)的高(gao)(gao)頻開關電(dian)(dian)(dian)源(yuan)(yuan)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)。可(ke)以(yi)通過模(mo)塊的串聯(lian)(lian),做成(cheng)高(gao)(gao)壓(ya)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi);也可(ke)以(yi)通過模(mo)塊的并聯(lian)(lian),做成(cheng)大電(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi);還(huan)可(ke)以(yi)通過模(mo)塊的串聯(lian)(lian)和并聯(lian)(lian),做成(cheng)高(gao)(gao)電(dian)(dian)(dian)壓(ya)、大電(dian)(dian)(dian)流的大功率(lv)(lv)(lv)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)。該開關電(dian)(dian)(dian)源(yuan)(yuan)充(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)還(huan)具有(you)根據電(dian)(dian)(dian)池管理(li)系統(tong)(BMS)的信(xin)息(xi),自動(dong)調(diao)節充(chong)(chong)電(dian)(dian)(dian)參數和自動(dong)保護(hu)電(dian)(dian)(dian)池的功能。
c)種脈(mo)沖(chong)充(chong)電器,結構(gou)比較(jiao)復(fu)朵(duo),技(ji)術難(nan)度較(jiao)大。脈(mo)沖(chong)充(chong)電可以減少電池在充(chong)電時(shi)產生的(de)(de)極化現象,從而提高電池的(de)(de)充(chong)電效率,減少充(chong)電時(shi)間,實(shi)現快速(su)充(chong)電。
以上說明,電能變成化(hua)學能是一個十(shi)分復雜的過程(cheng),必須有(you)充電器和(he)BMS協同工作,才能完(wan)成這一工作。
