鋰(li)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)器(qi)原(yuan)(yuan)理(li)圖(tu)(tu)是(shi)什(shen)么呢(ni)?在充(chong)電(dian)(dian)(dian)時,手機和電(dian)(dian)(dian)動車使(shi)用的(de)充(chong)電(dian)(dian)(dian)器(qi)多為(wei)鋰(li)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)器(qi),那么你知道鋰(li)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)器(qi)原(yuan)(yuan)理(li)圖(tu)(tu)是(shi)什(shen)么呢(ni)?下(xia)面世(shi)界工廠網小編就和大家聊(liao)(liao)聊(liao)(liao)鋰(li)電(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)器(qi)原(yuan)(yuan)理(li)圖(tu)(tu),也長長見識。

  鋰(li)(li)離子(zi)(zi)(zi)電(dian)池(chi)具有單只端電(dian)壓(ya)高、比(bi)容量(liang)大(da)等(deng)優點,但其充(chong)(chong)(chong)電(dian)必須使(shi)用(yong)專用(yong)充(chong)(chong)(chong)電(dian)器,因為它在過充(chong)(chong)(chong)電(dian)時極易損壞。鋰(li)(li)離子(zi)(zi)(zi)電(dian)池(chi)充(chong)(chong)(chong)電(dian)器之所以(yi)稱“新創意”,是(shi)因為它除監視電(dian)池(chi)的充(chong)(chong)(chong)電(dian)狀態(tai)外,還能分階(jie)段控制(zhi)電(dian)池(chi)的最大(da)充(chong)(chong)(chong)電(dian)電(dian)流。用(yong)本充(chong)(chong)(chong)電(dian)器充(chong)(chong)(chong)電(dian)開始時,充(chong)(chong)(chong)電(dian)電(dian)流從10mA依(yi)次遞增至(zhi)270mA,當電(dian)量(liang)充(chong)(chong)(chong)至(zhi)70%左右時,自動改用(yong)最大(da)220mA充(chong)(chong)(chong)電(dian),然后依(yi)次改為最大(da)170mA、120mA和70mA,最后以(yi)10mA左右的涓(juan)流結束(shu)充(chong)(chong)(chong)電(dian)。這(zhe)種充(chong)(chong)(chong)電(dian)方法(fa)可以(yi)較大(da)限度地(di)將鋰(li)(li)離子(zi)(zi)(zi)電(dian)池(chi)充(chong)(chong)(chong)足。

  本裝置電(dian)(dian)(dian)(dian)(dian)路(lu)如附圖所示。IC1構成(cheng)頻率約1Hz1的多諧振蕩器,IC2構成(cheng)脈(mo)沖(chong)(chong)頻率6分(fen)配(pei)器,IC3構成(cheng)充電(dian)(dian)(dian)(dian)(dian)執行電(dian)(dian)(dian)(dian)(dian)路(lu)。通(tong)電(dian)(dian)(dian)(dian)(dian)后(hou)IC2復位(wei),Q0輸出(chu)高(gao)電(dian)(dian)(dian)(dian)(dian)平(ping)(ping),這時(shi)IC3輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓僅1.25V,電(dian)(dian)(dian)(dian)(dian)路(lu)由+15V經(jing)R1給(gei)電(dian)(dian)(dian)(dian)(dian)池提供約10mA的充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。通(tong)電(dian)(dian)(dian)(dian)(dian)后(hou)IC1起振,其(qi)③腳輸出(chu)的脈(mo)沖(chong)(chong)觸發(fa)IC2工作,使(shi)輸出(chu)端Q1~Q5依(yi)(yi)次(ci)出(chu)現高(gao)電(dian)(dian)(dian)(dian)(dian)平(ping)(ping),經(jing)不同的分(fen)壓電(dian)(dian)(dian)(dian)(dian)阻(zu)分(fen)壓后(hou),IC3的輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓按6V、7V、8V、9V、10V依(yi)(yi)次(ci)遞(di)增,充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)也因此(ci)(ci)在(zai)70mA至270mA之間依(yi)(yi)次(ci)遞(di)增。當(dang)Q6輸出(chu)高(gao)電(dian)(dian)(dian)(dian)(dian)平(ping)(ping)時(shi)IC2被復位(wei),此(ci)(ci)后(hou)電(dian)(dian)(dian)(dian)(dian)路(lu)在(zai)IC1輸出(chu)脈(mo)沖(chong)(chong)的作用下重復上(shang)述過程(cheng)。
