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“電動車快速充電”設(she)備，誰知卻暗藏隱(yin)患(huan)。

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)動車電(dian)(dian)池正常的使用(yong)(yong)壽命是2~3年，如(ru)果經常使用(yong)(yong)電(dian)(dian)動車快速充(chong)電(dian)(dian)站充(chong)電(dian)(dian)的話(hua)，也許一年不到(dao)就(jiu)需要更(geng)換電(dian)(dian)池了。

電(dian)動車使用的(de)鉛酸電(dian)池充(chong)(chong)電(dian)分為兩步，剛開始是快速(su)充(chong)(chong)電(dian)，然后進行涓流充(chong)(chong)電(dian)，這樣(yang)才可(ke)以充(chong)(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次左右，經常快速充電會縮短電池(chi)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)(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站的(de)(de)工作原理就是將電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)調大，快(kuai)(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)是9A左右，而正(zheng)(zheng)常充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是1.5A-2A，相比之下(xia)也就是快(kuai)(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)站的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)是家(jia)庭(ting)的(de)(de)5-6倍，加大了電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)從而實現快(kuai)(kuai)速(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)目(mu)的(de)(de)。沒有脈沖保護，短時(shi)間充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)效果明顯(xian)，但是為電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)極板(ban)(ban)損害非常大，加速(su)極板(ban)(ban)的(de)(de)硫化，老化，導致極板(ban)(ban)脫落，擊穿(chuan)!而且現在(zai)市(shi)場上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)動車的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)90%以上(shang)都是鉛酸電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，正(zheng)(zheng)常情(qing)況(kuang)下(xia)是不允(yun)許(xu)加大電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)。

另外，電(dian)(dian)(dian)動車快(kuai)速(su)充(chong)電(dian)(dian)(dian)站有的(de)(de)是高電(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)，有的(de)(de)是高電(dian)(dian)(dian)壓充(chong)電(dian)(dian)(dian)，快(kuai)速(su)充(chong)電(dian)(dian)(dian)會導致電(dian)(dian)(dian)瓶極板翹曲變(bian)形(xing)、酸液(ye)濃(nong)度增大，從而對電(dian)(dian)(dian)瓶造成損(sun)害。所以還是盡量避免(mian)使用電(dian)(dian)(dian)動車快(kuai)速(su)充(chong)電(dian)(dian)(dian)站給自家的(de)(de)電(dian)(dian)(dian)動車充(chong)電(dian)(dian)(dian)。
