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(bei)，誰知卻暗(an)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)(che)電(dian)池正(zheng)常的使(shi)用(yong)壽命是(shi)2~3年，如果經常使(shi)用(yong)電(dian)動車(che)(che)快速充電(dian)站(zhan)充電(dian)的話(hua)，也(ye)許(xu)一年不到就(jiu)需要(yao)更換電(dian)池了(le)。

電動車使用的鉛酸電池(chi)充電分為兩步，剛(gang)開始是快速(su)充電，然后進行涓(juan)流充電，這(zhe)樣才可以充足。

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(chang)快速充電會(hui)縮短(duan)電池的使用壽(shou)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)(dian)(dian)動車(che)快(kuai)(kuai)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)工作原理(li)就是(shi)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)調大，快(kuai)(kuai)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)9A左右，而(er)正常充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)是(shi)1.5A-2A，相比之(zhi)下也就是(shi)快(kuai)(kuai)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)家庭的(de)(de)5-6倍，加大了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)從而(er)實現快(kuai)(kuai)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)目(mu)的(de)(de)。沒有脈沖保護，短時間充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)效果(guo)明顯，但是(shi)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)極(ji)板(ban)(ban)損害非常大，加速極(ji)板(ban)(ban)的(de)(de)硫(liu)化，老(lao)化，導致極(ji)板(ban)(ban)脫(tuo)落，擊穿!而(er)且現在市(shi)場上電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車(che)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)90%以上都是(shi)鉛酸(suan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，正常情況下是(shi)不允許加大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)。

另外(wai)，電(dian)(dian)(dian)(dian)(dian)動(dong)車快速(su)(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)站有(you)的是(shi)高電(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，有(you)的是(shi)高電(dian)(dian)(dian)(dian)(dian)壓充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，快速(su)(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)會導(dao)致電(dian)(dian)(dian)(dian)(dian)瓶極板翹曲變形、酸(suan)液濃度(du)增大，從而(er)對電(dian)(dian)(dian)(dian)(dian)瓶造成損害。所以還(huan)是(shi)盡量避免使(shi)用電(dian)(dian)(dian)(dian)(dian)動(dong)車快速(su)(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)站給自家(jia)的電(dian)(dian)(dian)(dian)(dian)動(dong)車充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。
