新能源汽車能改快充嗎

如果(guo)新能源汽車(che)原本沒有快充功能的(de)(de)話是不能后期加裝(zhuang)的(de)(de)。因(yin)(yin)為電(dian)池的(de)(de)電(dian)壓(ya)和電(dian)容量的(de)(de)原因(yin)(yin)，后期加裝(zhuang)對車(che)子的(de)(de)使(shi)用很不好。

第(di)一(yi)是(shi)(shi)因為快充的電壓(ya)很高(gao)(gao)，我們的車(che)輛動(dong)力電池的容量那(nei)么(me)高(gao)(gao)。第(di)二是(shi)(shi)車(che)輛的電控管理系(xi)統不(bu)具(ju)備(bei)此功能。第(di)三是(shi)(shi)線(xian)束(shu)接口以(yi)及(ji)整(zheng)車(che)控制器，軟件硬件都不(bu)具(ju)備(bei)快充。所(suo)以(yi)加裝的話相當于(yu)把車(che)子換新(xin)了。很不(bu)劃算也(ye)很難(nan)加裝。

新能源汽車快充和慢充的區別

1、充電(dian)速度(du)不同

新能源汽車快充僅(jin)需(xu)要(yao)一個(ge)小時(shi)(shi)就可以將(jiang)(jiang)電池充到百分(fen)之八十的電量；新能源汽車慢(man)充需(xu)要(yao)8到10個(ge)小時(shi)(shi)才能將(jiang)(jiang)電池電量完全充滿(man)。

2、接口不同

快速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)口(kou)中間有兩(liang)條(tiao)母線(xian)(xian)分別為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)正負，而(er)且(qie)在整個充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過程(cheng)當中電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流都非(fei)常(chang)大所(suo)(suo)以母線(xian)(xian)也非(fei)常(chang)粗。而(er)慢速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)則(ze)需要使用到零線(xian)(xian)火線(xian)(xian)還有地(di)線(xian)(xian)三根(gen)母線(xian)(xian)，所(suo)(suo)以在中間部(bu)位有三條(tiao)線(xian)(xian)，但是慢速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)需要的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流并不(bu)高所(suo)(suo)以接(jie)口(kou)也相對更(geng)細。由(you)于這兩(liang)種充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)口(kou)不(bu)同(tong)，所(suo)(suo)以在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的時候如果選擇的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)樁(zhuang)和車輛不(bu)一(yi)致，是插不(bu)上去的。

3、充(chong)電原理不同

從充(chong)電(dian)(dian)(dian)(dian)的原理來看(kan)快速(su)(su)充(chong)電(dian)(dian)(dian)(dian)和慢(man)(man)(man)速(su)(su)充(chong)電(dian)(dian)(dian)(dian)存在(zai)較大(da)差異，快速(su)(su)充(chong)電(dian)(dian)(dian)(dian)是直接通過(guo)充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)本身自帶的充(chong)電(dian)(dian)(dian)(dian)機(ji)將工業用(yong)電(dian)(dian)(dian)(dian)轉(zhuan)換為(wei)電(dian)(dian)(dian)(dian)動車(che)(che)需要的直流(liu)電(dian)(dian)(dian)(dian)，然(ran)(ran)后直接通過(guo)充(chong)電(dian)(dian)(dian)(dian)槍送(song)入(ru)動力(li)電(dian)(dian)(dian)(dian)池。而(er)慢(man)(man)(man)速(su)(su)充(chong)電(dian)(dian)(dian)(dian)則是直接通過(guo)充(chong)電(dian)(dian)(dian)(dian)槍將220伏的家(jia)用(yong)電(dian)(dian)(dian)(dian)送(song)入(ru)到車(che)(che)載充(chong)電(dian)(dian)(dian)(dian)機(ji)，然(ran)(ran)后通過(guo)車(che)(che)載充(chong)電(dian)(dian)(dian)(dian)機(ji)再把220伏的交流(liu)電(dian)(dian)(dian)(dian)轉(zhuan)化為(wei)車(che)(che)輛需要使用(yong)的直流(liu)電(dian)(dian)(dian)(dian)然(ran)(ran)后再送(song)入(ru)動力(li)電(dian)(dian)(dian)(dian)池。所以如果想通過(guo)慢(man)(man)(man)速(su)(su)充(chong)電(dian)(dian)(dian)(dian)接口將充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)的直流(liu)電(dian)(dian)(dian)(dian)送(song)動力(li)電(dian)(dian)(dian)(dian)池這個肯定是不可(ke)能實現的。

4、充電電流不同

快速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁也(ye)叫(jiao)做直流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)槍輸(shu)出為(wei)直流(liu)(liu)電(dian)(dian)(dian)(dian)，而(er)且充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)功(gong)率(lv)都要(yao)在15KW以上，目前主流(liu)(liu)的充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁功(gong)率(lv)在40KW居多。而(er)慢速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁也(ye)叫(jiao)做交(jiao)流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁，這種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)槍輸(shu)出電(dian)(dian)(dian)(dian)流(liu)(liu)為(wei)交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)同(tong)時(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)功(gong)率(lv)比較低(di)，常見的交(jiao)流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁功(gong)率(lv)有3.5KW和7KW兩(liang)種。所以想要(yao)直接把直流(liu)(liu)電(dian)(dian)(dian)(dian)送入慢充(chong)(chong)(chong)接口，強(qiang)大的電(dian)(dian)(dian)(dian)流(liu)(liu)也(ye)會(hui)瞬間燒(shao)壞充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)接口線(xian)路(lu)以及車載充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)機。

快充與慢充的優缺點

一、慢充優缺點

優點：以較低的速度給(gei)設備電(dian)池充電(dian)不僅可以減少熱(re)量和電(dian)池壓(ya)力，而且對電(dian)池的長(chang)期健康也有好處。

缺(que)點(dian)：缺(que)點(dian)非(fei)常明顯，充(chong)電時間較長，僅滿足白天運(yun)作，晚上休(xiu)息(xi)的(de)車輛。

二、快充的優(you)缺點(dian)

優點(dian)：充電速度快，相(xiang)當(dang)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)站(zhan)的(de)充(chong)電(dian)(dian)(dian)樁(zhuang)確(que)實電(dian)(dian)(dian)壓(ya)比較高，例如一臺240KW的(de)充(chong)電(dian)(dian)(dian)樁(zhuang)，它(ta)的(de)輸出電(dian)(dian)(dian)壓(ya)可以達到750V，電(dian)(dian)(dian)流可達480A。而慢(man)充(chong)的(de)交流充(chong)電(dian)(dian)(dian)樁(zhuang)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)是220v。至于新(xin)能(neng)(neng)源車(che)高壓(ya)充(chong)電(dian)(dian)(dian)安全(quan)嗎這個問題，現在的(de)充(chong)電(dian)(dian)(dian)樁(zhuang)都會內置(zhi)漏電(dian)(dian)(dian)保護(hu)、過壓(ya)保護(hu)、過流保護(hu)、溫度檢測等功能(neng)(neng)，所以安全(quan)性還是有保障的(de)。
