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(ke)見“電動(dong)車快速充電”設備，誰(shui)知卻暗(an)藏隱患。

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)動車電(dian)池(chi)正常(chang)的使用(yong)壽命是2~3年，如(ru)果經(jing)常(chang)使用(yong)電(dian)動車快(kuai)速充電(dian)站充電(dian)的話(hua)，也許一(yi)年不到就需(xu)要更(geng)換電(dian)池(chi)了。

電動車使用的鉛酸電池充(chong)電分為兩步，剛開始是快速(su)充(chong)電，然后進(jin)行(xing)涓(juan)流充(chong)電，這樣才可(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次左(zuo)右，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)(dian)(dian)(dian)(dian)動(dong)車快速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站的工作原理就(jiu)是(shi)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流調大(da)(da)，快速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流是(shi)9A左(zuo)右(you)，而正常(chang)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)是(shi)1.5A-2A，相(xiang)比之(zhi)下(xia)也(ye)就(jiu)是(shi)快速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流是(shi)家庭的5-6倍，加(jia)大(da)(da)了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流從而實現(xian)快速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的目(mu)的。沒有脈沖(chong)保護，短(duan)時(shi)間(jian)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)效(xiao)果明顯(xian)，但是(shi)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池極板(ban)損害非常(chang)大(da)(da)，加(jia)速極板(ban)的硫化，老化，導致極板(ban)脫落(luo)，擊(ji)穿(chuan)!而且現(xian)在市場上電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池90%以(yi)上都是(shi)鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池，正常(chang)情況下(xia)是(shi)不允許加(jia)大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的。

另外，電(dian)(dian)動(dong)車快速(su)充電(dian)(dian)站有的(de)(de)是(shi)(shi)高電(dian)(dian)流充電(dian)(dian)，有的(de)(de)是(shi)(shi)高電(dian)(dian)壓充電(dian)(dian)，快速(su)充電(dian)(dian)會導致電(dian)(dian)瓶(ping)極板翹曲(qu)變形、酸液(ye)濃度增大，從(cong)而對電(dian)(dian)瓶(ping)造成(cheng)損(sun)害。所以還是(shi)(shi)盡量避免使(shi)用電(dian)(dian)動(dong)車快速(su)充電(dian)(dian)站給自家的(de)(de)電(dian)(dian)動(dong)車充電(dian)(dian)。
