新能源汽車能改快充嗎

如果新(xin)能(neng)源汽(qi)車(che)原(yuan)本沒有快充功能(neng)的(de)話是不能(neng)后期(qi)加(jia)裝的(de)。因為電(dian)池(chi)的(de)電(dian)壓(ya)和電(dian)容量的(de)原(yuan)因，后期(qi)加(jia)裝對(dui)車(che)子的(de)使用很(hen)不好。

第一是(shi)因為快(kuai)充的(de)(de)電(dian)壓很高，我們的(de)(de)車(che)輛(liang)動力(li)電(dian)池的(de)(de)容量那么高。第二是(shi)車(che)輛(liang)的(de)(de)電(dian)控管(guan)理系統不具備此功(gong)能。第三是(shi)線束(shu)接口以及(ji)整車(che)控制器(qi)，軟件硬件都(dou)不具備快(kuai)充。所以加(jia)裝(zhuang)的(de)(de)話相當于把(ba)車(che)子(zi)換新了。很不劃算也很難加(jia)裝(zhuang)。

新能源汽車快充和慢充的區別

1、充(chong)電(dian)速(su)度不同

新能源汽車快充僅需(xu)要一(yi)個小時就可以(yi)將電池充到(dao)百分之八十的電量；新能(neng)源(yuan)汽車慢充需(xu)要8到(dao)10個小時才能(neng)將電池電量完全充滿。

2、接口不同

快速充(chong)電(dian)(dian)(dian)接(jie)口中(zhong)間(jian)有兩條(tiao)母線分別為(wei)電(dian)(dian)(dian)源(yuan)正(zheng)負，而且(qie)在(zai)(zai)整個(ge)充(chong)電(dian)(dian)(dian)過程當(dang)中(zhong)電(dian)(dian)(dian)流都非常大所以(yi)母線也(ye)非常粗。而慢速充(chong)電(dian)(dian)(dian)則需要(yao)使(shi)用到零線火線還(huan)有地線三根母線，所以(yi)在(zai)(zai)中(zhong)間(jian)部位有三條(tiao)線，但是慢速充(chong)電(dian)(dian)(dian)需要(yao)的(de)(de)電(dian)(dian)(dian)流并(bing)不(bu)(bu)高(gao)所以(yi)接(jie)口也(ye)相對更細。由于這(zhe)兩種充(chong)電(dian)(dian)(dian)接(jie)口不(bu)(bu)同，所以(yi)在(zai)(zai)充(chong)電(dian)(dian)(dian)的(de)(de)時候(hou)如果選擇的(de)(de)充(chong)電(dian)(dian)(dian)樁和車輛(liang)不(bu)(bu)一(yi)致，是插(cha)不(bu)(bu)上去(qu)的(de)(de)。

3、充電原(yuan)理不(bu)同

從充電(dian)(dian)的(de)(de)(de)原(yuan)理(li)來(lai)看快(kuai)速(su)(su)充電(dian)(dian)和(he)慢(man)(man)速(su)(su)充電(dian)(dian)存在較大(da)差異，快(kuai)速(su)(su)充電(dian)(dian)是(shi)直(zhi)(zhi)接(jie)(jie)通(tong)過充電(dian)(dian)樁本身(shen)自帶(dai)的(de)(de)(de)充電(dian)(dian)機(ji)將工業用電(dian)(dian)轉(zhuan)換為電(dian)(dian)動(dong)車(che)需要的(de)(de)(de)直(zhi)(zhi)流(liu)電(dian)(dian)，然后直(zhi)(zhi)接(jie)(jie)通(tong)過充電(dian)(dian)槍(qiang)送入(ru)(ru)動(dong)力(li)電(dian)(dian)池。而慢(man)(man)速(su)(su)充電(dian)(dian)則是(shi)直(zhi)(zhi)接(jie)(jie)通(tong)過充電(dian)(dian)槍(qiang)將220伏(fu)的(de)(de)(de)家(jia)用電(dian)(dian)送入(ru)(ru)到車(che)載充電(dian)(dian)機(ji)，然后通(tong)過車(che)載充電(dian)(dian)機(ji)再把220伏(fu)的(de)(de)(de)交流(liu)電(dian)(dian)轉(zhuan)化(hua)為車(che)輛需要使用的(de)(de)(de)直(zhi)(zhi)流(liu)電(dian)(dian)然后再送入(ru)(ru)動(dong)力(li)電(dian)(dian)池。所以(yi)如果想通(tong)過慢(man)(man)速(su)(su)充電(dian)(dian)接(jie)(jie)口將充電(dian)(dian)樁的(de)(de)(de)直(zhi)(zhi)流(liu)電(dian)(dian)送動(dong)力(li)電(dian)(dian)池這個肯定是(shi)不可能(neng)實(shi)現(xian)的(de)(de)(de)。

4、充電電流不同

快速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁也叫做(zuo)直(zhi)流(liu)(liu)(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)槍(qiang)(qiang)輸出(chu)為直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)，而且充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)功率都(dou)要(yao)在(zai)15KW以(yi)上(shang)，目前(qian)主流(liu)(liu)(liu)的(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁功率在(zai)40KW居多。而慢速(su)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁也叫做(zuo)交流(liu)(liu)(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁，這種(zhong)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)槍(qiang)(qiang)輸出(chu)電(dian)(dian)(dian)流(liu)(liu)(liu)為交流(liu)(liu)(liu)電(dian)(dian)(dian)同時充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)功率比較低，常(chang)見(jian)的(de)交流(liu)(liu)(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁功率有3.5KW和7KW兩種(zhong)。所以(yi)想要(yao)直(zhi)接(jie)(jie)把直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)送入慢充(chong)(chong)(chong)(chong)接(jie)(jie)口，強大的(de)電(dian)(dian)(dian)流(liu)(liu)(liu)也會(hui)瞬間燒壞充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)接(jie)(jie)口線路以(yi)及車載(zai)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)機。

快充與慢充的優缺點

一、慢充優缺點

優點(dian)：以較(jiao)低的(de)速度給設備電池(chi)充電不(bu)僅(jin)可(ke)以減(jian)少熱量(liang)和電池(chi)壓力，而且對電池(chi)的(de)長期健康也(ye)有好處。

缺(que)點：缺(que)點非常(chang)明顯，充電時(shi)間較(jiao)長，僅滿足白天運作，晚上休(xiu)息的車輛。

二、快(kuai)充(chong)的優缺點

優(you)點：充電速度(du)快(kuai)，相當節約時間。

缺點：充電設備安裝要求和成本非常高。快速充電的電流電壓較高，短時間內對電池的沖擊較大，容易令電池的活性物質脫落和電池發熱，無論電池再完美，長期快速充電終究影響電池的使用壽命。

新能源汽車快充電壓多少伏

目前快(kuai)充(chong)(chong)站的充(chong)(chong)電(dian)(dian)樁(zhuang)確實(shi)電(dian)(dian)壓比較(jiao)高，例如一臺(tai)240KW的充(chong)(chong)電(dian)(dian)樁(zhuang)，它(ta)的輸出電(dian)(dian)壓可(ke)以達到750V，電(dian)(dian)流可(ke)達480A。而慢充(chong)(chong)的交流充(chong)(chong)電(dian)(dian)樁(zhuang)充(chong)(chong)電(dian)(dian)電(dian)(dian)壓是(shi)220v。至于新能(neng)源(yuan)車高壓充(chong)(chong)電(dian)(dian)安全嗎這個問題，現(xian)在的充(chong)(chong)電(dian)(dian)樁(zhuang)都會內置(zhi)漏電(dian)(dian)保護(hu)、過壓保護(hu)、過流保護(hu)、溫度檢測(ce)等功(gong)能(neng)，所以安全性還是(shi)有保障的。
