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(tou)隨處可見“電動車快速充電”設備，誰知卻(que)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)(dian)(dian)(dian)動(dong)車(che)電(dian)(dian)(dian)(dian)池正常(chang)的使用(yong)壽命是2~3年，如果經常(chang)使用(yong)電(dian)(dian)(dian)(dian)動(dong)車(che)快速(su)充(chong)電(dian)(dian)(dian)(dian)站充(chong)電(dian)(dian)(dian)(dian)的話，也許(xu)一年不到就需要更換(huan)電(dian)(dian)(dian)(dian)池了。

電(dian)動(dong)車使用的鉛酸電(dian)池(chi)充(chong)電(dian)分為(wei)兩步(bu)，剛開始是快(kuai)速充(chong)電(dian)，然(ran)后進行涓流充(chong)電(dian)，這樣才可(ke)以充(chong)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，經(jing)常(chang)快速充電會(hui)縮短電池的使(shi)用壽命(ming)。

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)動(dong)(dong)車快速充(chong)電(dian)(dian)(dian)(dian)站(zhan)的工作原理就是(shi)將(jiang)電(dian)(dian)(dian)(dian)流調大，快速充(chong)電(dian)(dian)(dian)(dian)站(zhan)的電(dian)(dian)(dian)(dian)流是(shi)9A左右(you)，而(er)正(zheng)常充(chong)電(dian)(dian)(dian)(dian)是(shi)1.5A-2A，相比之下(xia)也就是(shi)快速充(chong)電(dian)(dian)(dian)(dian)站(zhan)的電(dian)(dian)(dian)(dian)流是(shi)家庭的5-6倍，加大了電(dian)(dian)(dian)(dian)流從(cong)而(er)實(shi)現快速充(chong)電(dian)(dian)(dian)(dian)的目的。沒有脈沖(chong)保(bao)護，短時間充(chong)電(dian)(dian)(dian)(dian)效果明顯，但(dan)是(shi)為(wei)電(dian)(dian)(dian)(dian)池極板(ban)損害非常大，加速極板(ban)的硫化，老化，導致極板(ban)脫落，擊穿!而(er)且(qie)現在(zai)市場上(shang)電(dian)(dian)(dian)(dian)動(dong)(dong)車的電(dian)(dian)(dian)(dian)池90%以上(shang)都(dou)是(shi)鉛酸電(dian)(dian)(dian)(dian)池，正(zheng)常情況(kuang)下(xia)是(shi)不允許加大電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)的。

另外(wai)，電(dian)(dian)動(dong)(dong)車(che)(che)快(kuai)速充(chong)(chong)電(dian)(dian)站有(you)的是高(gao)電(dian)(dian)流充(chong)(chong)電(dian)(dian)，有(you)的是高(gao)電(dian)(dian)壓充(chong)(chong)電(dian)(dian)，快(kuai)速充(chong)(chong)電(dian)(dian)會導致電(dian)(dian)瓶極板翹(qiao)曲變形、酸液濃度增(zeng)大，從而對電(dian)(dian)瓶造成損害。所以還是盡量(liang)避免使用電(dian)(dian)動(dong)(dong)車(che)(che)快(kuai)速充(chong)(chong)電(dian)(dian)站給自家的電(dian)(dian)動(dong)(dong)車(che)(che)充(chong)(chong)電(dian)(dian)。
