鋰(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)器(qi)(qi)(qi)(qi)原理(li)圖(tu)是(shi)什(shen)么(me)呢(ni)？在充(chong)電(dian)(dian)時，手機和電(dian)(dian)動車使(shi)用的充(chong)電(dian)(dian)器(qi)(qi)(qi)(qi)多為鋰(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)器(qi)(qi)(qi)(qi)，那(nei)么(me)你知(zhi)道鋰(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)器(qi)(qi)(qi)(qi)原理(li)圖(tu)是(shi)什(shen)么(me)呢(ni)？下面世(shi)界工廠網小編就(jiu)和大(da)家聊聊鋰(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)器(qi)(qi)(qi)(qi)原理(li)圖(tu)，也(ye)長長見(jian)識。

　　鋰(li)離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)池(chi)具有(you)單(dan)只端電(dian)(dian)(dian)(dian)(dian)壓高(gao)、比(bi)容量大等優點，但其充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)必須(xu)使用專用充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器，因為它在過充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時極易損壞。鋰(li)離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器之所以(yi)稱“新創意”，是因為它除監視電(dian)(dian)(dian)(dian)(dian)池(chi)的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)狀態外(wai)，還能分階(jie)段控制電(dian)(dian)(dian)(dian)(dian)池(chi)的最大充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流。用本充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)開始時，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流從(cong)10mA依次遞增至(zhi)270mA，當(dang)電(dian)(dian)(dian)(dian)(dian)量充(chong)(chong)(chong)至(zhi)70%左右時，自(zi)動改用最大220mA充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，然后(hou)依次改為最大170mA、120mA和70mA，最后(hou)以(yi)10mA左右的涓流結束(shu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。這(zhe)種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方法可(ke)以(yi)較大限度地將鋰(li)離(li)子(zi)電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)足。
