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“電(dian)動車快(kuai)速充電(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。電動車電池正常的使(shi)用(yong)壽命是2~3年，如果經常使(shi)用(yong)電動車快速充電站(zhan)充電的話，也許(xu)一年不到就需要更換電池了(le)。

電(dian)(dian)動車使(shi)用的鉛酸電(dian)(dian)池充電(dian)(dian)分為兩步，剛開始是快速(su)充電(dian)(dian)，然后進(jin)行涓流充電(dian)(dian)，這樣才可以充足。

目前街頭(tou)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(you)，經常快速(su)充電會縮短(duan)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)動(dong)車(che)(che)快(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)的(de)(de)(de)工作(zuo)原理(li)就是(shi)將電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)調大(da)，快(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)9A左右(you)，而正(zheng)(zheng)常(chang)(chang)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是(shi)1.5A-2A，相比之下也就是(shi)快(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)家庭的(de)(de)(de)5-6倍，加(jia)大(da)了電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)從而實現(xian)快(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)目的(de)(de)(de)。沒有(you)脈(mo)沖(chong)保護，短時間充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)效(xiao)果明顯，但是(shi)為電(dian)(dian)(dian)(dian)(dian)(dian)池極板損害非常(chang)(chang)大(da)，加(jia)速(su)極板的(de)(de)(de)硫化(hua)，老化(hua)，導致(zhi)極板脫落(luo)，擊穿!而且現(xian)在(zai)市場上電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)(che)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池90%以上都是(shi)鉛酸(suan)電(dian)(dian)(dian)(dian)(dian)(dian)池，正(zheng)(zheng)常(chang)(chang)情況下是(shi)不(bu)允(yun)許加(jia)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)。

另(ling)外，電(dian)(dian)(dian)動車(che)快(kuai)(kuai)速充(chong)電(dian)(dian)(dian)站有的(de)是高(gao)電(dian)(dian)(dian)流(liu)充(chong)電(dian)(dian)(dian)，有的(de)是高(gao)電(dian)(dian)(dian)壓(ya)充(chong)電(dian)(dian)(dian)，快(kuai)(kuai)速充(chong)電(dian)(dian)(dian)會(hui)導(dao)致(zhi)電(dian)(dian)(dian)瓶(ping)極板(ban)翹曲變形、酸液濃度增大，從而對電(dian)(dian)(dian)瓶(ping)造成損害。所以還是盡量(liang)避(bi)免(mian)使用電(dian)(dian)(dian)動車(che)快(kuai)(kuai)速充(chong)電(dian)(dian)(dian)站給(gei)自家(jia)的(de)電(dian)(dian)(dian)動車(che)充(chong)電(dian)(dian)(dian)。
