現在(zai)在(zai)大街小巷，隨處(chu)都(dou)能夠看到(dao)共享充(chong)電寶(bao)的投放點，里面(mian)有不少的充電(dian)寶(bao)等著被租(zu)賃。可能有的朋友(you)就會(hui)問了，充電(dian)寶(bao)整天(tian)呆在(zai)里面(mian)處(chu)于充電(dian)狀態不會(hui)壞(huai)掉嘛？不用擔心，飛天(tian)鷹為您解答疑惑。

 現在的(de)合格充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)寶(bao)(bao)廠家都會給充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)寶(bao)(bao)安(an)裝(zhuang)上過充(chong)(chong)(chong)(chong)保護(hu)裝(zhuang)置，當充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)寶(bao)(bao)接入市電(dian)(dian)(dian)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，電(dian)(dian)(dian)量達到最大狀態時，起到過充(chong)(chong)(chong)(chong)保護(hu)電(dian)(dian)(dian)路作用，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)寶(bao)(bao)不(bu)再充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)。這樣(yang)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)寶(bao)(bao)就(jiu)不(bu)會發生因為電(dian)(dian)(dian)量過多而發生損壞或(huo)爆炸的(de)事情。這個與手機充(chong)(chong)(chong)(chong)滿(man)電(dian)(dian)(dian)自動不(bu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)原理相類似。

一般過充保(bao)護都是(shi)通過用(yong)去檢測電壓實現(xian)的，芯片內(nei)部在基準設(she)置狀態下(xia)（一般(ban)為3.7V）。當基(ji)準(zhun)慢(man)慢(man)上(shang)升，當上(shang)升到VSS-VDD設(she)計值(zhi)時，這時的(de)電(dian)(dian)壓(ya)(ya)就(jiu)是保(bao)護(hu)過(guo)充(chong)關斷電(dian)(dian)壓(ya)(ya)，通過(guo)邏(luo)輯關系輸出低或者高電(dian)(dian)平來控制外部控制電(dian)(dian)路來實(shi)現(xian)過(guo)充(chong)保(bao)護(hu)。當電(dian)(dian)壓(ya)(ya)緩慢(man)下降(jiang)時設(she)置VSS-VDD電(dian)(dian)壓(ya)(ya)值(zhi)來取基(ji)準(zhun)值(zhi)當基(ji)準(zhun)檢測到在(zai)設(she)置以下時，這是邏(luo)輯關系解除過(guo)充(chong)保(bao)護(hu)。所以大家在(zai)外觀(guan)上(shang)看起來共(gong)享(xiang)充(chong)電(dian)(dian)寶的(de)指(zhi)示燈顯(xian)示一直在(zai)哪里充(chong)電(dian)(dian)，實(shi)際上(shang)內部還是在(zai)保(bao)護(hu)電(dian)(dian)池的(de)
