鋰(li)電池充(chong)(chong)電器(qi)(qi)原(yuan)(yuan)理圖(tu)是什(shen)么呢？在充(chong)(chong)電時，手機和電動(dong)車使用(yong)的充(chong)(chong)電器(qi)(qi)多為鋰(li)電池充(chong)(chong)電器(qi)(qi)，那么你(ni)知道(dao)鋰(li)電池充(chong)(chong)電器(qi)(qi)原(yuan)(yuan)理圖(tu)是什(shen)么呢？下(xia)面世(shi)界工廠網小(xiao)編就和大家聊聊鋰(li)電池充(chong)(chong)電器(qi)(qi)原(yuan)(yuan)理圖(tu)，也長(chang)長(chang)見(jian)識。

　　鋰離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)具(ju)有(you)單只端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)壓高、比容(rong)量大(da)(da)等優點，但其(qi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)必(bi)須使用(yong)專(zhuan)用(yong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器，因為它(ta)在過充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)極易損壞(huai)。鋰離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器之所以(yi)稱(cheng)“新創意”，是(shi)因為它(ta)除監視電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態外(wai)，還(huan)能(neng)分階段控制電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的最(zui)(zui)大(da)(da)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流。用(yong)本(ben)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)開始時(shi)，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流從(cong)10mA依次遞增至270mA，當電(dian)(dian)(dian)(dian)(dian)(dian)量充(chong)至70%左右(you)時(shi)，自(zi)動改用(yong)最(zui)(zui)大(da)(da)220mA充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，然后依次改為最(zui)(zui)大(da)(da)170mA、120mA和70mA，最(zui)(zui)后以(yi)10mA左右(you)的涓流結束充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。這種充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)方(fang)法可(ke)以(yi)較大(da)(da)限度地(di)將鋰離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)足。
