有很多人給電動車充電的時候，電動車充電器紅(hong)燈(deng)不停的閃，充(chong)了(le)(le)五六個小(xiao)時也(ye)就三格電(dian)(dian)，一騎車就掉電(dian)(dian)。把電(dian)(dian)器(qi)插(cha)在電(dian)(dian)源上，這頭(tou)沒(mei)(mei)插(cha)電(dian)(dian)池(chi)，是一個紅(hong)燈(deng)一個綠(lv)燈(deng)。這么說(shuo)充(chong)電(dian)(dian)器(qi)應該沒(mei)(mei)問題。重新(xin)插(cha)上電(dian)(dian)池(chi)再充(chong)電(dian)(dian)時，兩(liang)個燈(deng)正常都(dou)是紅(hong)的，沒(mei)(mei)過多久紅(hong)燈(deng)又開(kai)始閃？遇到這種情況是電(dian)(dian)池(chi)壞了(le)(le)，還是充(chong)電(dian)(dian)器(qi)壞了(le)(le)？

　　事實上，充電器有識別電壓，也就是咱們說的啟動電壓。如果你電池電壓過低的話，充電器識別不了，就不會識別的，所以會閃，有的充電器閃一個燈，有的充電器會兩燈一起閃，因為里面的變壓初級繞組出到次級繞組出來以后就不識電壓了。
　　如長期(qi)不使用，不對蓄(xu)電(dian)(dian)(dian)(dian)池進行任(ren)何處理，這也是(shi)不對的，一(yi)個(ge)滿電(dian)(dian)(dian)(dian)的蓄(xu)電(dian)(dian)(dian)(dian)池，在2-3周(zhou)內，就(jiu)會(hui)出現虧電(dian)(dian)(dian)(dian)的狀況，如果持續一(yi)個(ge)月，其(qi)內部的電(dian)(dian)(dian)(dian)量就(jiu)會(hui)釋放干(gan)凈。。不過即便(bian)是(shi)蓄(xu)電(dian)(dian)(dian)(dian)池單(dan)獨存放，它自身也會(hui)產生自放電(dian)(dian)(dian)(dian)現象。所以建議要2-3個(ge)月為蓄(xu)電(dian)(dian)(dian)(dian)池進行一(yi)次充電(dian)(dian)(dian)(dian)。
