鋰電(dian)(dian)池充(chong)電(dian)(dian)器(qi)原理圖是什(shen)么呢(ni)？在充(chong)電(dian)(dian)時，手機(ji)和(he)(he)電(dian)(dian)動(dong)車使(shi)用的充(chong)電(dian)(dian)器(qi)多為鋰電(dian)(dian)池充(chong)電(dian)(dian)器(qi)，那么你知(zhi)道(dao)鋰電(dian)(dian)池充(chong)電(dian)(dian)器(qi)原理圖是什(shen)么呢(ni)？下面世界工廠網小編(bian)就(jiu)和(he)(he)大家聊(liao)聊(liao)鋰電(dian)(dian)池充(chong)電(dian)(dian)器(qi)原理圖，也長長見識。

　　鋰(li)(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)具有單只端(duan)電(dian)(dian)(dian)(dian)壓高、比容量(liang)大(da)等優(you)點(dian)，但(dan)其充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)必須使用專用充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)，因(yin)為(wei)它(ta)在過充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時極(ji)易(yi)損壞(huai)。鋰(li)(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)之(zhi)所以稱“新(xin)創意”，是因(yin)為(wei)它(ta)除(chu)監視電(dian)(dian)(dian)(dian)池(chi)的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)狀態外，還(huan)能分(fen)階段(duan)控制(zhi)電(dian)(dian)(dian)(dian)池(chi)的最大(da)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)。用本充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)開始時，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)從10mA依次遞增(zeng)至(zhi)270mA，當電(dian)(dian)(dian)(dian)量(liang)充(chong)(chong)(chong)至(zhi)70%左(zuo)右時，自動改用最大(da)220mA充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，然后依次改為(wei)最大(da)170mA、120mA和(he)70mA，最后以10mA左(zuo)右的涓流(liu)(liu)結束充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。這種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)方法(fa)可以較(jiao)大(da)限度(du)地將(jiang)鋰(li)(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)足(zu)。

　　本裝置電(dian)(dian)(dian)路如附圖(tu)所示。IC1構(gou)成頻率約1Hz１的(de)(de)多(duo)諧振蕩器(qi)，IC2構(gou)成脈沖(chong)頻率６分配器(qi)，IC3構(gou)成充(chong)電(dian)(dian)(dian)執(zhi)行電(dian)(dian)(dian)路。通(tong)電(dian)(dian)(dian)后(hou)IC2復(fu)(fu)位(wei)，Q0輸出(chu)(chu)(chu)高(gao)電(dian)(dian)(dian)平，這時IC3輸出(chu)(chu)(chu)電(dian)(dian)(dian)壓(ya)(ya)僅1.25V，電(dian)(dian)(dian)路由+15V經(jing)R1給電(dian)(dian)(dian)池提供約10mA的(de)(de)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)。通(tong)電(dian)(dian)(dian)后(hou)IC1起振，其③腳(jiao)輸出(chu)(chu)(chu)的(de)(de)脈沖(chong)觸發IC2工作(zuo)，使(shi)輸出(chu)(chu)(chu)端Q1~Q5依次出(chu)(chu)(chu)現高(gao)電(dian)(dian)(dian)平，經(jing)不同的(de)(de)分壓(ya)(ya)電(dian)(dian)(dian)阻(zu)分壓(ya)(ya)后(hou)，IC3的(de)(de)輸出(chu)(chu)(chu)電(dian)(dian)(dian)壓(ya)(ya)按6V、7V、8V、9V、10V依次遞增，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)也因此(ci)在70mA至270mA之(zhi)間依次遞增。當Q6輸出(chu)(chu)(chu)高(gao)電(dian)(dian)(dian)平時IC2被復(fu)(fu)位(wei)，此(ci)后(hou)電(dian)(dian)(dian)路在IC1輸出(chu)(chu)(chu)脈沖(chong)的(de)(de)作(zuo)用下重復(fu)(fu)上述過程。
