一、充電手電筒充不進電是為什么
電池壞了,一般(ban)市面(mian)上的led手電(dian)(dian)筒的電(dian)(dian)池(chi)都(dou)是(shi)(shi)鉛酸電(dian)(dian)池(chi)。充電(dian)(dian)電(dian)(dian)路(lu)都(dou)是(shi)(shi)工頻變壓器加(jia)簡單整流,或是(shi)(shi)串(chuan)塑膠電(dian)(dian)容限流整流。
致(zhi)命的(de)缺點是不(bu)能(neng)充滿后自動(dong)停充,也不(bu)能(neng)恒(heng)流限壓。幾次長時(shi)間充電(dian)就把電(dian)池充報廢了。
充(chong)電(dian)(dian)時(shi)間太短的話(hua)也會(hui)造成電(dian)(dian)池欠充(chong),極板硫化損壞(huai)。還有就是沒有虧電(dian)(dian)檢測電(dian)(dian)路,電(dian)(dian)池電(dian)(dian)量放完不能自動切(qie)斷(duan)電(dian)(dian)源造成電(dian)(dian)池過(guo)放電(dian)(dian)損壞(huai)。
好的手電筒是鋰電池(chi),充電器(qi)、LED驅動(dong)電路有CB等(deng)安規環保認證。
二、充電手電筒常見故障
1、手電筒電路斷路
內(nei)部接線(xian)斷路(lu)、插頭內(nei)部黃(huang)銅彈簧(huang)導電片變(bian)形,找到斷線(xian)部分接通或彈簧(huang)片變(bian)形整形。
2、充電(dian)(dian)電(dian)(dian)路電(dian)(dian)子元件損壞(huai)
檢查(cha)降壓(ya)電(dian)容(rong)、整流(liu)二極管。更(geng)換損壞元件。
3、充電電池(chi)失效
一種是(shi)鉛酸電池,電池極板(ban)容易老化(hua)。清洗極板(ban),更(geng)換蒸餾(liu)水(shui)(或純凈水(shui),效(xiao)果差些。)。部(bu)分可以修復。
另一種采(cai)用鎳氫電(dian)(dian)(dian)池,或鎘(ge)鎳電(dian)(dian)(dian)池。這一類電(dian)(dian)(dian)池有(you)可(ke)能(neng)壽命未到期,但因記(ji)憶效應而(er)充(chong)(chong)(chong)(chong)不進電(dian)(dian)(dian),這種情況(kuang)多為使用時未充(chong)(chong)(chong)(chong)分充(chong)(chong)(chong)(chong)、放(fang)電(dian)(dian)(dian)造成。這時可(ke)對電(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian),需加(jia)放(fang)電(dian)(dian)(dian)限流電(dian)(dian)(dian)阻(zu),再(zai)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian),部分可(ke)以修復。
三、充電手電筒充不進電怎么辦
最簡單的(de)方(fang)法(fa),找個(ge)滿電的(de)好電池,和(he)過放(fang)(fang)的(de)電池,正(zheng)負極對應直接(jie)接(jie)上,給過放(fang)(fang)的(de)充電,如果(guo)電壓能起來,再(zai)用充電器充就行,不行的(de)話建議換一個(ge)。
四、充電手電筒的保養措施
1、存放(fang)時勿虧電
虧電狀態(tai)是指電池使用后沒(mei)及時充電。虧電狀態(tai)閑(xian)置時間越(yue)長,電池損壞越(yue)嚴重。
2、不(bu)要曝曬
不能在陽光下曝曬。溫度過高的(de)話,環境會(hui)使(shi)蓄電(dian)(dian)(dian)(dian)池(chi)內部壓力增加,使(shi)電(dian)(dian)(dian)(dian)池(chi)限壓閥(fa)被迫(po)自動開啟,直(zhi)接后果(guo)就是增加電(dian)(dian)(dian)(dian)池(chi)的(de)失(shi)水量,而電(dian)(dian)(dian)(dian)池(chi)過度失(shi)水會(hui)引發電(dian)(dian)(dian)(dian)池(chi)活(huo)性下降,加速極(ji)板的(de)軟化(hua),充電(dian)(dian)(dian)(dian)時起鼓、殼(ke)體發熱、變(bian)形等致命損(sun)傷。
3、定期(qi)檢驗
在使用過程中(zhong),如果放(fang)電時間內(nei)突然下(xia)降,很(hen)有可能是電池組中(zhong)最(zui)少(shao)有一塊電池出(chu)現斷格、極(ji)(ji)板軟化、極(ji)(ji)板活性物質脫落短路(lu)現象。此時,應及時到專(zhuan)業電池修復(fu)機構進(jin)行檢查、修4、復及配組
盡量(liang)避(bi)免瞬間大電流(liu)放(fang)電,大電流(liu)放(fang)電容易(yi)導致產硫(liu)酸(suan)鉛結晶(jing),而損(sun)害(hai)電池極板的物理(li)性能。
5、正確掌握(wo)充電時間
在使用過程中,應(ying)根據實際情況(kuang)把(ba)握充(chong)(chong)電時間(jian),一般蓄電池都在夜(ye)間(jian)充(chong)(chong)電,平均時間(jian)在8小時左右。電(dian)池(chi)很快會充(chong)滿(man),繼續充(chong)電(dian)會出現過(guo)充(chong)現象,導致電(dian)池(chi)失水、發熱,降低電(dian)池(chi)的壽(shou)命(ming)。所以,蓄電(dian)池(chi)以放電(dian)深(shen)度為60%-70%時充(chong)一次(ci)電。
6、避免充電時(shi)拔熱插(cha)頭
充電器輸出(chu)插頭(tou)松動、接(jie)觸面(mian)氧(yang)化(hua)現象會導(dao)致充電插頭(tou)變熱,發(fa)(fa)熱時間過長會導(dao)致充電插頭(tou)短路(lu),直接(jie)損害充電器,帶(dai)來不必(bi)要損失。所以(yi)發(fa)(fa)現上述情(qing)況時,應該及時清除(chu)氧(yang)化(hua)物或更換(huan)接(jie)插件。
