新能源汽車能改快充嗎

如果新能(neng)(neng)源汽(qi)車原(yuan)本沒有快充功能(neng)(neng)的話是不(bu)能(neng)(neng)后期加(jia)裝的。因為電(dian)(dian)池的電(dian)(dian)壓和電(dian)(dian)容(rong)量的原(yuan)因，后期加(jia)裝對(dui)車子的使用(yong)很不(bu)好。

第(di)一是(shi)(shi)因為快充的(de)電(dian)壓很高，我們的(de)車(che)輛動力電(dian)池的(de)容量那么(me)高。第(di)二(er)是(shi)(shi)車(che)輛的(de)電(dian)控管理系統(tong)不具(ju)備此功能。第(di)三是(shi)(shi)線(xian)束接口以及整車(che)控制器(qi)，軟件硬件都不具(ju)備快充。所以加裝的(de)話相當于把(ba)車(che)子換新了。很不劃算(suan)也很難加裝。

新能源汽車快充和慢充的區別

1、充電(dian)速(su)度不同

新能源汽車快充(chong)僅需(xu)要(yao)一個小時(shi)就(jiu)可以將(jiang)電(dian)(dian)池充(chong)到百分之八(ba)十的電(dian)(dian)量(liang)；新(xin)能源(yuan)汽車(che)慢充(chong)需(xu)要(yao)8到10個小時(shi)才能將(jiang)電(dian)(dian)池電(dian)(dian)量(liang)完全充(chong)滿。

2、接口不同

快速(su)充(chong)電(dian)(dian)(dian)(dian)接口中間有(you)兩條(tiao)母(mu)(mu)(mu)線(xian)分別為電(dian)(dian)(dian)(dian)源正(zheng)負，而且在整個充(chong)電(dian)(dian)(dian)(dian)過(guo)程當中電(dian)(dian)(dian)(dian)流(liu)都非常大所以(yi)母(mu)(mu)(mu)線(xian)也非常粗。而慢速(su)充(chong)電(dian)(dian)(dian)(dian)則需要使用到零線(xian)火線(xian)還(huan)有(you)地(di)線(xian)三根母(mu)(mu)(mu)線(xian)，所以(yi)在中間部(bu)位有(you)三條(tiao)線(xian)，但是慢速(su)充(chong)電(dian)(dian)(dian)(dian)需要的電(dian)(dian)(dian)(dian)流(liu)并不高所以(yi)接口也相對更細。由于這兩種(zhong)充(chong)電(dian)(dian)(dian)(dian)接口不同(tong)，所以(yi)在充(chong)電(dian)(dian)(dian)(dian)的時(shi)候如果選(xuan)擇的充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)和(he)車輛不一(yi)致，是插不上去的。

3、充電原理不同

從(cong)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)原理來看快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)和慢速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)存在較大(da)差異(yi)，快(kuai)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是(shi)直(zhi)接(jie)通(tong)過(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)樁本(ben)身自帶(dai)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機將(jiang)工業用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)轉(zhuan)換為電(dian)(dian)(dian)(dian)(dian)(dian)動車需要的(de)(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，然(ran)后直(zhi)接(jie)通(tong)過(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍送入(ru)動力(li)電(dian)(dian)(dian)(dian)(dian)(dian)池。而慢速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)則(ze)是(shi)直(zhi)接(jie)通(tong)過(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍將(jiang)220伏(fu)的(de)(de)家(jia)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)送入(ru)到(dao)車載充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機，然(ran)后通(tong)過(guo)車載充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機再(zai)把220伏(fu)的(de)(de)交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)轉(zhuan)化為車輛(liang)需要使用(yong)的(de)(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)然(ran)后再(zai)送入(ru)動力(li)電(dian)(dian)(dian)(dian)(dian)(dian)池。所以如果(guo)想通(tong)過(guo)慢速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)接(jie)口(kou)將(jiang)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)樁的(de)(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)送動力(li)電(dian)(dian)(dian)(dian)(dian)(dian)池這個肯定是(shi)不(bu)可(ke)能實現(xian)的(de)(de)。

4、充(chong)電(dian)電(dian)流不同

快(kuai)速充(chong)(chong)(chong)電(dian)(dian)(dian)樁也叫做直(zhi)(zhi)流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)樁充(chong)(chong)(chong)電(dian)(dian)(dian)槍(qiang)輸(shu)出為直(zhi)(zhi)流(liu)電(dian)(dian)(dian)，而且充(chong)(chong)(chong)電(dian)(dian)(dian)功(gong)(gong)率(lv)都(dou)要在15KW以(yi)上，目前主流(liu)的充(chong)(chong)(chong)電(dian)(dian)(dian)樁功(gong)(gong)率(lv)在40KW居多。而慢速充(chong)(chong)(chong)電(dian)(dian)(dian)樁也叫做交(jiao)(jiao)流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)樁，這種(zhong)充(chong)(chong)(chong)電(dian)(dian)(dian)槍(qiang)輸(shu)出電(dian)(dian)(dian)流(liu)為交(jiao)(jiao)流(liu)電(dian)(dian)(dian)同時充(chong)(chong)(chong)電(dian)(dian)(dian)功(gong)(gong)率(lv)比較(jiao)低，常見的交(jiao)(jiao)流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)樁功(gong)(gong)率(lv)有3.5KW和7KW兩(liang)種(zhong)。所以(yi)想要直(zhi)(zhi)接把(ba)直(zhi)(zhi)流(liu)電(dian)(dian)(dian)送(song)入(ru)慢充(chong)(chong)(chong)接口(kou)，強大的電(dian)(dian)(dian)流(liu)也會(hui)瞬間燒(shao)壞(huai)充(chong)(chong)(chong)電(dian)(dian)(dian)接口(kou)線路以(yi)及車載充(chong)(chong)(chong)電(dian)(dian)(dian)機。

快充與慢充的優缺點

一、慢充優缺點

優(you)點：以(yi)較低的速(su)度給設備電(dian)(dian)(dian)池充電(dian)(dian)(dian)不僅可以(yi)減少(shao)熱量和電(dian)(dian)(dian)池壓力，而且對電(dian)(dian)(dian)池的長期健(jian)康(kang)也有好(hao)處。

缺點：缺點非(fei)常(chang)明顯，充電時間較長，僅滿足白天運(yun)作，晚上休(xiu)息的車(che)輛。

二、快(kuai)充的優缺點

優點：充電速(su)度快(kuai)，相當節約時(shi)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

目前快充(chong)站的充(chong)電(dian)樁(zhuang)確實(shi)電(dian)壓(ya)(ya)比較高，例(li)如一臺(tai)240KW的充(chong)電(dian)樁(zhuang)，它的輸出電(dian)壓(ya)(ya)可以達到750V，電(dian)流(liu)可達480A。而(er)慢(man)充(chong)的交流(liu)充(chong)電(dian)樁(zhuang)充(chong)電(dian)電(dian)壓(ya)(ya)是220v。至于(yu)新能源車高壓(ya)(ya)充(chong)電(dian)安全嗎(ma)這個問題，現在的充(chong)電(dian)樁(zhuang)都會內置漏電(dian)保(bao)(bao)護、過壓(ya)(ya)保(bao)(bao)護、過流(liu)保(bao)(bao)護、溫度(du)檢測等功能，所以安全性還是有保(bao)(bao)障(zhang)的。
