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(chu)可見(jian)“電動(dong)車快速(su)充電”設備，誰知卻暗藏隱患(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)池正常的使用壽命是2~3年，如果經(jing)常使用電(dian)(dian)動車快速(su)充電(dian)(dian)站充電(dian)(dian)的話，也許(xu)一年不到就需(xu)要(yao)更換電(dian)(dian)池了(le)。

電動車使用的(de)鉛酸電池(chi)充(chong)(chong)電分(fen)為(wei)兩步(bu)，剛開始是快速充(chong)(chong)電，然(ran)后進行涓流充(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(jing)常快(kuai)速(su)充電會(hui)縮短(duan)電池的(de)使用壽命(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)動車(che)快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)的(de)(de)工作原理就是將電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)調(diao)大，快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)是9A左右(you)，而正常(chang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)是1.5A-2A，相比之下(xia)也就是快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)站(zhan)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)是家庭的(de)(de)5-6倍(bei)，加(jia)大了電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)從而實現快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)目的(de)(de)。沒有(you)脈沖(chong)保護，短時間充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)效(xiao)果明顯，但是為電(dian)(dian)(dian)(dian)池(chi)極板(ban)(ban)損害非(fei)常(chang)大，加(jia)速極板(ban)(ban)的(de)(de)硫化，老化，導致極板(ban)(ban)脫落，擊(ji)穿!而且現在(zai)市(shi)場上(shang)電(dian)(dian)(dian)(dian)動車(che)的(de)(de)電(dian)(dian)(dian)(dian)池(chi)90%以(yi)上(shang)都是鉛(qian)酸電(dian)(dian)(dian)(dian)池(chi)，正常(chang)情況下(xia)是不允(yun)許(xu)加(jia)大電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)。

另外，電(dian)(dian)動(dong)車(che)快速(su)充(chong)電(dian)(dian)站有的(de)是(shi)高電(dian)(dian)流充(chong)電(dian)(dian)，有的(de)是(shi)高電(dian)(dian)壓充(chong)電(dian)(dian)，快速(su)充(chong)電(dian)(dian)會導(dao)致(zhi)電(dian)(dian)瓶極板翹(qiao)曲變形(xing)、酸液濃(nong)度增大，從而對電(dian)(dian)瓶造成損(sun)害。所以還是(shi)盡(jin)量避免使用電(dian)(dian)動(dong)車(che)快速(su)充(chong)電(dian)(dian)站給自家的(de)電(dian)(dian)動(dong)車(che)充(chong)電(dian)(dian)。
