　　鋰(li)離子(zi)電(dian)(dian)池(chi)具有單只端電(dian)(dian)壓(ya)高(gao)、比(bi)容量大(da)(da)(da)等優點，但其(qi)充(chong)(chong)(chong)(chong)電(dian)(dian)必(bi)須使用(yong)專用(yong)充(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)，因(yin)(yin)為(wei)(wei)它在過充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)極易損壞。鋰(li)離子(zi)電(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)之所以稱(cheng)“新創意(yi)”，是(shi)因(yin)(yin)為(wei)(wei)它除監視電(dian)(dian)池(chi)的充(chong)(chong)(chong)(chong)電(dian)(dian)狀態外，還能分階(jie)段控(kong)制電(dian)(dian)池(chi)的最(zui)大(da)(da)(da)充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流。用(yong)本充(chong)(chong)(chong)(chong)電(dian)(dian)器(qi)充(chong)(chong)(chong)(chong)電(dian)(dian)開(kai)始時(shi)，充(chong)(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流從10mA依次遞增至270mA，當電(dian)(dian)量充(chong)(chong)(chong)(chong)至70%左右時(shi)，自動改(gai)用(yong)最(zui)大(da)(da)(da)220mA充(chong)(chong)(chong)(chong)電(dian)(dian)，然后依次改(gai)為(wei)(wei)最(zui)大(da)(da)(da)170mA、120mA和70mA，最(zui)后以10mA左右的涓流結(jie)束充(chong)(chong)(chong)(chong)電(dian)(dian)。這種充(chong)(chong)(chong)(chong)電(dian)(dian)方法可以較(jiao)大(da)(da)(da)限度地(di)將鋰(li)離子(zi)電(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)足(zu)。

　　本(ben)裝置電(dian)(dian)路如(ru)附圖所示。IC1構成頻率約1Hz１的(de)(de)多諧振蕩器，IC2構成脈沖(chong)頻率６分配(pei)器，IC3構成充電(dian)(dian)執行電(dian)(dian)路。通電(dian)(dian)后(hou)IC2復位，Q0輸出高電(dian)(dian)平，這時(shi)IC3輸出電(dian)(dian)壓(ya)僅1.25V，電(dian)(dian)路由(you)+15V經(jing)(jing)R1給(gei)電(dian)(dian)池(chi)提供約10mA的(de)(de)充電(dian)(dian)電(dian)(dian)流。通電(dian)(dian)后(hou)IC1起振，其③腳輸出的(de)(de)脈沖(chong)觸發IC2工(gong)作，使輸出端(duan)Q1~Q5依(yi)次出現高電(dian)(dian)平，經(jing)(jing)不同(tong)的(de)(de)分壓(ya)電(dian)(dian)阻(zu)分壓(ya)后(hou)，IC3的(de)(de)輸出電(dian)(dian)壓(ya)按6V、7V、8V、9V、10V依(yi)次遞增，充電(dian)(dian)電(dian)(dian)流也因此在(zai)70mA至(zhi)270mA之間依(yi)次遞增。當Q6輸出高電(dian)(dian)平時(shi)IC2被復位，此后(hou)電(dian)(dian)路在(zai)IC1輸出脈沖(chong)的(de)(de)作用下重復上述過程。
