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。在街頭隨處可見(jian)“電(dian)動車(che)快速(su)充電(dian)”設備，誰知卻暗藏隱患。

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(che)電(dian)池正常的(de)使用(yong)壽(shou)命是2~3年，如(ru)果經常使用(yong)電(dian)動車(che)快速充電(dian)站充電(dian)的(de)話，也許一年不到就(jiu)需要更換電(dian)池了。

電動車使用的鉛酸電池(chi)充(chong)(chong)電分為兩步，剛開始是快速充(chong)(chong)電，然后進行(xing)涓流充(chong)(chong)電，這樣才(cai)可以充(chong)(chong)足。

目前(qian)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次左右，經常快(kuai)速充電(dian)會縮短電(dian)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)動車快(kuai)速(su)(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站的(de)(de)(de)工作原理就是(shi)(shi)(shi)將電(dian)(dian)(dian)(dian)(dian)(dian)流調(diao)大，快(kuai)速(su)(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流是(shi)(shi)(shi)9A左右，而正常(chang)(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是(shi)(shi)(shi)1.5A-2A，相比之下(xia)也就是(shi)(shi)(shi)快(kuai)速(su)(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流是(shi)(shi)(shi)家庭的(de)(de)(de)5-6倍，加(jia)大了電(dian)(dian)(dian)(dian)(dian)(dian)流從而實(shi)現(xian)快(kuai)速(su)(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)目的(de)(de)(de)。沒(mei)有脈(mo)沖保(bao)護，短時間充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)效果(guo)明顯，但是(shi)(shi)(shi)為電(dian)(dian)(dian)(dian)(dian)(dian)池極(ji)板(ban)損(sun)害非常(chang)(chang)大，加(jia)速(su)(su)極(ji)板(ban)的(de)(de)(de)硫化，老化，導致極(ji)板(ban)脫落，擊(ji)穿!而且現(xian)在市場上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)動車的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池90%以上(shang)都(dou)是(shi)(shi)(shi)鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)池，正常(chang)(chang)情況下(xia)是(shi)(shi)(shi)不允許(xu)加(jia)大電(dian)(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)。

另外，電(dian)(dian)(dian)動(dong)車快(kuai)速(su)充電(dian)(dian)(dian)站有的是(shi)高(gao)電(dian)(dian)(dian)流充電(dian)(dian)(dian)，有的是(shi)高(gao)電(dian)(dian)(dian)壓充電(dian)(dian)(dian)，快(kuai)速(su)充電(dian)(dian)(dian)會導致電(dian)(dian)(dian)瓶(ping)極板翹曲變形、酸(suan)液濃(nong)度增大，從(cong)而對電(dian)(dian)(dian)瓶(ping)造(zao)成損害。所以還是(shi)盡量(liang)避免使用電(dian)(dian)(dian)動(dong)車快(kuai)速(su)充電(dian)(dian)(dian)站給自(zi)家的電(dian)(dian)(dian)動(dong)車充電(dian)(dian)(dian)。
