鋰(li)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器(qi)(qi)原(yuan)(yuan)(yuan)理圖是什么(me)呢(ni)？在充(chong)電(dian)(dian)(dian)時(shi)，手機和電(dian)(dian)(dian)動車使用(yong)的充(chong)電(dian)(dian)(dian)器(qi)(qi)多為鋰(li)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器(qi)(qi)，那么(me)你知道鋰(li)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器(qi)(qi)原(yuan)(yuan)(yuan)理圖是什么(me)呢(ni)？下(xia)面世界工廠網(wang)小(xiao)編(bian)就和大家聊(liao)聊(liao)鋰(li)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器(qi)(qi)原(yuan)(yuan)(yuan)理圖，也長長見(jian)識。

　　鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)具有(you)單只端電(dian)(dian)(dian)(dian)壓高、比容量(liang)大(da)等優點，但其充(chong)電(dian)(dian)(dian)(dian)必(bi)須(xu)使用(yong)(yong)專用(yong)(yong)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)，因為(wei)(wei)它在(zai)過充(chong)電(dian)(dian)(dian)(dian)時極易(yi)損壞。鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)之所以稱“新(xin)創意(yi)”，是因為(wei)(wei)它除監視電(dian)(dian)(dian)(dian)池(chi)(chi)的充(chong)電(dian)(dian)(dian)(dian)狀態外，還(huan)能分階段(duan)控制電(dian)(dian)(dian)(dian)池(chi)(chi)的最大(da)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)。用(yong)(yong)本充(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)充(chong)電(dian)(dian)(dian)(dian)開始(shi)時，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)從10mA依次(ci)遞增至(zhi)270mA，當電(dian)(dian)(dian)(dian)量(liang)充(chong)至(zhi)70%左右時，自動改用(yong)(yong)最大(da)220mA充(chong)電(dian)(dian)(dian)(dian)，然后依次(ci)改為(wei)(wei)最大(da)170mA、120mA和70mA，最后以10mA左右的涓流(liu)結束充(chong)電(dian)(dian)(dian)(dian)。這種充(chong)電(dian)(dian)(dian)(dian)方法可以較大(da)限度地將(jiang)鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)足。

　　本(ben)裝置電(dian)(dian)(dian)(dian)(dian)路如附圖所示。IC1構成頻(pin)率約1Hz１的(de)多諧振蕩器，IC2構成脈沖(chong)頻(pin)率６分配(pei)器，IC3構成充(chong)電(dian)(dian)(dian)(dian)(dian)執行(xing)電(dian)(dian)(dian)(dian)(dian)路。通電(dian)(dian)(dian)(dian)(dian)后IC2復位(wei)，Q0輸(shu)(shu)出(chu)(chu)高電(dian)(dian)(dian)(dian)(dian)平，這(zhe)時IC3輸(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)壓僅1.25V，電(dian)(dian)(dian)(dian)(dian)路由+15V經(jing)R1給電(dian)(dian)(dian)(dian)(dian)池提供約10mA的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)。通電(dian)(dian)(dian)(dian)(dian)后IC1起振，其③腳輸(shu)(shu)出(chu)(chu)的(de)脈沖(chong)觸發(fa)IC2工作，使輸(shu)(shu)出(chu)(chu)端Q1~Q5依次出(chu)(chu)現高電(dian)(dian)(dian)(dian)(dian)平，經(jing)不同(tong)的(de)分壓電(dian)(dian)(dian)(dian)(dian)阻分壓后，IC3的(de)輸(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)壓按6V、7V、8V、9V、10V依次遞增，充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)也因(yin)此(ci)在70mA至(zhi)270mA之(zhi)間依次遞增。當(dang)Q6輸(shu)(shu)出(chu)(chu)高電(dian)(dian)(dian)(dian)(dian)平時IC2被復位(wei)，此(ci)后電(dian)(dian)(dian)(dian)(dian)路在IC1輸(shu)(shu)出(chu)(chu)脈沖(chong)的(de)作用(yong)下重復上述過程(cheng)。
