新能源汽車能改快充嗎

如(ru)果(guo)新能源汽車(che)原(yuan)(yuan)本沒(mei)有(you)快(kuai)充功(gong)能的(de)話是不能后期加(jia)裝的(de)。因為(wei)電(dian)池的(de)電(dian)壓和電(dian)容量的(de)原(yuan)(yuan)因，后期加(jia)裝對車(che)子(zi)的(de)使(shi)用很不好。

第一是因為快充的(de)電(dian)壓很高，我們的(de)車(che)輛(liang)動力電(dian)池的(de)容量那么高。第二是車(che)輛(liang)的(de)電(dian)控(kong)管理系(xi)統不具備(bei)此功(gong)能。第三是線束接(jie)口以(yi)及整(zheng)車(che)控(kong)制(zhi)器(qi)，軟件(jian)硬(ying)件(jian)都不具備(bei)快充。所以(yi)加裝(zhuang)的(de)話(hua)相當于把車(che)子換新了。很不劃算(suan)也很難加裝(zhuang)。

新能源汽車快充和慢充的區別

1、充(chong)電速度不同

新能源汽車快充僅(jin)需(xu)要(yao)一個小(xiao)時就可以(yi)將電池充到(dao)百分之八十的(de)電量；新能源汽車慢充需(xu)要(yao)8到(dao)10個小(xiao)時才能將電池電量完全充滿(man)。

2、接口不同

快速充(chong)電(dian)(dian)接口(kou)中間(jian)有兩(liang)條母線(xian)分別為電(dian)(dian)源正負，而且在(zai)整個充(chong)電(dian)(dian)過程(cheng)當(dang)中電(dian)(dian)流都非常大所(suo)以母線(xian)也非常粗。而慢速充(chong)電(dian)(dian)則需要(yao)使用到零線(xian)火線(xian)還有地(di)線(xian)三根母線(xian)，所(suo)以在(zai)中間(jian)部位(wei)有三條線(xian)，但是(shi)慢速充(chong)電(dian)(dian)需要(yao)的(de)電(dian)(dian)流并不(bu)高所(suo)以接口(kou)也相對(dui)更細。由于這兩(liang)種充(chong)電(dian)(dian)接口(kou)不(bu)同(tong)，所(suo)以在(zai)充(chong)電(dian)(dian)的(de)時(shi)候如果選擇的(de)充(chong)電(dian)(dian)樁和車輛不(bu)一(yi)致，是(shi)插(cha)不(bu)上去的(de)。

3、充電原理不(bu)同(tong)

從充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)的(de)(de)(de)(de)原理來看快速(su)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)和慢速(su)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)存在較大(da)差異，快速(su)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)是(shi)直接(jie)通(tong)過充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁(zhuang)本(ben)身自帶的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)機將工業用(yong)電(dian)(dian)(dian)轉(zhuan)(zhuan)換(huan)為電(dian)(dian)(dian)動(dong)車需(xu)要的(de)(de)(de)(de)直流(liu)(liu)電(dian)(dian)(dian)，然后(hou)直接(jie)通(tong)過充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)槍送入(ru)動(dong)力(li)電(dian)(dian)(dian)池。而慢速(su)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)則是(shi)直接(jie)通(tong)過充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)槍將220伏(fu)的(de)(de)(de)(de)家用(yong)電(dian)(dian)(dian)送入(ru)到車載(zai)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)機，然后(hou)通(tong)過車載(zai)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)機再(zai)把220伏(fu)的(de)(de)(de)(de)交流(liu)(liu)電(dian)(dian)(dian)轉(zhuan)(zhuan)化為車輛需(xu)要使用(yong)的(de)(de)(de)(de)直流(liu)(liu)電(dian)(dian)(dian)然后(hou)再(zai)送入(ru)動(dong)力(li)電(dian)(dian)(dian)池。所(suo)以如果想通(tong)過慢速(su)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)接(jie)口將充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)樁(zhuang)的(de)(de)(de)(de)直流(liu)(liu)電(dian)(dian)(dian)送動(dong)力(li)電(dian)(dian)(dian)池這個肯定是(shi)不(bu)可能實(shi)現(xian)的(de)(de)(de)(de)。

4、充電電流不同(tong)

快(kuai)速充(chong)(chong)(chong)(chong)電樁也(ye)叫(jiao)做直流(liu)(liu)(liu)充(chong)(chong)(chong)(chong)電樁充(chong)(chong)(chong)(chong)電槍輸(shu)出(chu)為(wei)直流(liu)(liu)(liu)電，而(er)且充(chong)(chong)(chong)(chong)電功率(lv)都要在15KW以(yi)(yi)(yi)上，目前主流(liu)(liu)(liu)的(de)(de)充(chong)(chong)(chong)(chong)電樁功率(lv)在40KW居多。而(er)慢速充(chong)(chong)(chong)(chong)電樁也(ye)叫(jiao)做交(jiao)流(liu)(liu)(liu)充(chong)(chong)(chong)(chong)電樁，這種充(chong)(chong)(chong)(chong)電槍輸(shu)出(chu)電流(liu)(liu)(liu)為(wei)交(jiao)流(liu)(liu)(liu)電同時充(chong)(chong)(chong)(chong)電功率(lv)比(bi)較低(di)，常見的(de)(de)交(jiao)流(liu)(liu)(liu)充(chong)(chong)(chong)(chong)電樁功率(lv)有3.5KW和(he)7KW兩(liang)種。所以(yi)(yi)(yi)想要直接(jie)把(ba)直流(liu)(liu)(liu)電送入(ru)慢充(chong)(chong)(chong)(chong)接(jie)口，強大的(de)(de)電流(liu)(liu)(liu)也(ye)會瞬間燒壞充(chong)(chong)(chong)(chong)電接(jie)口線(xian)路以(yi)(yi)(yi)及車載充(chong)(chong)(chong)(chong)電機。

快充與慢充的優缺點

一、慢充優缺點

優點(dian)：以(yi)較低(di)的(de)速(su)度給(gei)設備電池(chi)充電不(bu)僅可以(yi)減(jian)少熱量和電池(chi)壓力，而且對電池(chi)的(de)長期健康也有好處。

缺點(dian)：缺點(dian)非常明(ming)顯，充(chong)電時間較長，僅滿足白(bai)天運作，晚(wan)上休息(xi)的車輛。

二、快充的優缺點

優點(dian)：充電速度快，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(mu)前快充站(zhan)的(de)(de)充電(dian)(dian)樁(zhuang)確實電(dian)(dian)壓(ya)比較高(gao)，例如一臺(tai)240KW的(de)(de)充電(dian)(dian)樁(zhuang)，它的(de)(de)輸出電(dian)(dian)壓(ya)可以(yi)達(da)到(dao)750V，電(dian)(dian)流(liu)可達(da)480A。而慢充的(de)(de)交流(liu)充電(dian)(dian)樁(zhuang)充電(dian)(dian)電(dian)(dian)壓(ya)是220v。至于新能源(yuan)車(che)高(gao)壓(ya)充電(dian)(dian)安(an)全嗎這個問題，現在的(de)(de)充電(dian)(dian)樁(zhuang)都會內置漏電(dian)(dian)保(bao)(bao)護(hu)、過壓(ya)保(bao)(bao)護(hu)、過流(liu)保(bao)(bao)護(hu)、溫度檢測等功能，所(suo)以(yi)安(an)全性還是有保(bao)(bao)障的(de)(de)。
