電動車快速充電站對電瓶有傷害嗎

對于電動車車主來說，騎車半路上沒了電源，那是件郁悶的事。快捷和輕便的電動車快速充電站的出現，為很多市民的出行提供了便利。在街(jie)頭隨處可見(jian)“電(dian)(dian)動(dong)車快速充電(dian)(dian)”設備(bei)，誰(shui)知卻暗藏(zang)隱患。

目前市場上所使用的快速充電站，其工作電流一般在7~10A左右，充電電流一般是原廠充電器的3~5倍，經常快速充電就會對充電器造成不可逆的影響，嚴重影響使用壽命。電(dian)(dian)動車(che)電(dian)(dian)池正(zheng)常的使(shi)用壽命是2~3年，如果經常使(shi)用電(dian)(dian)動車(che)快速(su)充電(dian)(dian)站充電(dian)(dian)的話，也許一年不到(dao)就需要更換電(dian)(dian)池了。

電(dian)(dian)動車使用的鉛(qian)酸電(dian)(dian)池(chi)充(chong)電(dian)(dian)分(fen)為兩步，剛開始(shi)是快速(su)充(chong)電(dian)(dian)，然后進行(xing)涓(juan)流充(chong)電(dian)(dian)，這樣才(cai)可(ke)以充(chong)足。

目前街頭的“快速充電”設備沒有涓流充電過程，因此不可能充足電。并且快速充電還有可能導致電池極板變形、酸液濃度增大，從而對電池造成損害。電池的壽命是以充電次數來計算的，一般為300次(ci)左右(you)，經常快速充電會縮短電池的使用壽命。

快速充電站為什么會損傷電池

這個就要從解快速充電站的工作原理來說：

電(dian)(dian)(dian)動(dong)車快速(su)充(chong)電(dian)(dian)(dian)站(zhan)的工作(zuo)原(yuan)理就(jiu)是將(jiang)電(dian)(dian)(dian)流(liu)調大(da)，快速(su)充(chong)電(dian)(dian)(dian)站(zhan)的電(dian)(dian)(dian)流(liu)是9A左(zuo)右，而(er)(er)正常(chang)充(chong)電(dian)(dian)(dian)是1.5A-2A，相(xiang)比之下(xia)也(ye)就(jiu)是快速(su)充(chong)電(dian)(dian)(dian)站(zhan)的電(dian)(dian)(dian)流(liu)是家庭(ting)的5-6倍(bei)，加(jia)大(da)了電(dian)(dian)(dian)流(liu)從而(er)(er)實現快速(su)充(chong)電(dian)(dian)(dian)的目的。沒有脈沖保護(hu)，短時(shi)間(jian)充(chong)電(dian)(dian)(dian)效果明顯，但是為(wei)電(dian)(dian)(dian)池極板損害非(fei)常(chang)大(da)，加(jia)速(su)極板的硫化，老化，導致極板脫(tuo)落，擊穿!而(er)(er)且(qie)現在市場上電(dian)(dian)(dian)動(dong)車的電(dian)(dian)(dian)池90%以上都是鉛酸電(dian)(dian)(dian)池，正常(chang)情況下(xia)是不允許加(jia)大(da)電(dian)(dian)(dian)流(liu)充(chong)電(dian)(dian)(dian)的。

另(ling)外(wai)，電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)快(kuai)速充電(dian)(dian)(dian)(dian)站有的是高(gao)電(dian)(dian)(dian)(dian)流充電(dian)(dian)(dian)(dian)，有的是高(gao)電(dian)(dian)(dian)(dian)壓充電(dian)(dian)(dian)(dian)，快(kuai)速充電(dian)(dian)(dian)(dian)會導致電(dian)(dian)(dian)(dian)瓶極板翹曲變形、酸(suan)液濃度增(zeng)大(da)，從而對電(dian)(dian)(dian)(dian)瓶造成損(sun)害。所以(yi)還是盡量避(bi)免使用電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)快(kuai)速充電(dian)(dian)(dian)(dian)站給自(zi)家的電(dian)(dian)(dian)(dian)動(dong)(dong)車(che)充電(dian)(dian)(dian)(dian)。
