新能源汽車能改快充嗎

如(ru)果新能(neng)源汽車原(yuan)(yuan)本沒有快充功能(neng)的(de)話(hua)是不(bu)能(neng)后(hou)(hou)期加裝(zhuang)的(de)。因為(wei)電(dian)(dian)池的(de)電(dian)(dian)壓和電(dian)(dian)容量的(de)原(yuan)(yuan)因，后(hou)(hou)期加裝(zhuang)對車子的(de)使(shi)用很不(bu)好。

第一是因為快充的(de)電壓很高，我們的(de)車輛動力電池的(de)容量那么高。第二是車輛的(de)電控(kong)管理(li)系統不(bu)具備此功(gong)能。第三是線束接口以及(ji)整車控(kong)制(zhi)器，軟件(jian)(jian)硬件(jian)(jian)都不(bu)具備快充。所以加(jia)裝的(de)話相當于把車子(zi)換(huan)新了。很不(bu)劃算也很難加(jia)裝。

新能源汽車快充和慢充的區別

1、充(chong)電速度不同

新能源汽車快充僅需要一(yi)個(ge)小時(shi)就可以將電(dian)池(chi)充到百分之八十的(de)電(dian)量；新能源汽車慢充需要8到10個(ge)小時(shi)才能將電(dian)池(chi)電(dian)量完全充滿。

2、接口不同

快速充電(dian)(dian)接(jie)口(kou)中間有兩(liang)條母線(xian)分別為電(dian)(dian)源正(zheng)負，而且(qie)在(zai)整個(ge)充電(dian)(dian)過程(cheng)當(dang)中電(dian)(dian)流都非常大所(suo)(suo)(suo)以(yi)母線(xian)也非常粗。而慢速充電(dian)(dian)則需要使(shi)用到零(ling)線(xian)火(huo)線(xian)還有地線(xian)三根母線(xian)，所(suo)(suo)(suo)以(yi)在(zai)中間部位(wei)有三條線(xian)，但(dan)是(shi)慢速充電(dian)(dian)需要的電(dian)(dian)流并不(bu)高(gao)所(suo)(suo)(suo)以(yi)接(jie)口(kou)也相對更細。由于這兩(liang)種(zhong)充電(dian)(dian)接(jie)口(kou)不(bu)同，所(suo)(suo)(suo)以(yi)在(zai)充電(dian)(dian)的時候如(ru)果選(xuan)擇的充電(dian)(dian)樁和(he)車輛(liang)不(bu)一致，是(shi)插不(bu)上去的。

3、充(chong)電原理不同

從充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)原理來看快(kuai)速(su)(su)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)和慢速(su)(su)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)存在較大差異，快(kuai)速(su)(su)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)是直接通(tong)過(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)樁本身(shen)自帶的(de)(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)將工業用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)轉換為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)(dong)車(che)需要的(de)(de)(de)(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，然后(hou)(hou)直接通(tong)過(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)槍送(song)入動(dong)(dong)(dong)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。而(er)慢速(su)(su)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)則是直接通(tong)過(guo)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)槍將220伏的(de)(de)(de)(de)家(jia)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)送(song)入到車(che)載充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)，然后(hou)(hou)通(tong)過(guo)車(che)載充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)再把220伏的(de)(de)(de)(de)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)轉化為車(che)輛需要使用(yong)的(de)(de)(de)(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)然后(hou)(hou)再送(song)入動(dong)(dong)(dong)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。所(suo)以(yi)如(ru)果想通(tong)過(guo)慢速(su)(su)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)接口將充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)樁的(de)(de)(de)(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)送(song)動(dong)(dong)(dong)力電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)這個肯(ken)定是不可能實現的(de)(de)(de)(de)。

4、充(chong)電(dian)電(dian)流不同

快速(su)充(chong)電(dian)(dian)(dian)(dian)(dian)樁也(ye)叫(jiao)做直流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)樁充(chong)電(dian)(dian)(dian)(dian)(dian)槍輸(shu)出(chu)(chu)為直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，而且(qie)充(chong)電(dian)(dian)(dian)(dian)(dian)功率(lv)都要(yao)在15KW以上，目前主流(liu)(liu)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)樁功率(lv)在40KW居多。而慢速(su)充(chong)電(dian)(dian)(dian)(dian)(dian)樁也(ye)叫(jiao)做交流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)樁，這種(zhong)充(chong)電(dian)(dian)(dian)(dian)(dian)槍輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)為交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)同時充(chong)電(dian)(dian)(dian)(dian)(dian)功率(lv)比較低，常(chang)見的(de)交流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)(dian)樁功率(lv)有3.5KW和(he)7KW兩種(zhong)。所以想要(yao)直接(jie)把直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)送入慢充(chong)接(jie)口，強大的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)也(ye)會瞬間(jian)燒壞(huai)充(chong)電(dian)(dian)(dian)(dian)(dian)接(jie)口線路以及(ji)車載充(chong)電(dian)(dian)(dian)(dian)(dian)機。

快充與慢充的優缺點

一、慢充優缺點

優點(dian)：以較低(di)的速(su)度給設備電(dian)池充電(dian)不僅(jin)可以減少熱量和(he)電(dian)池壓(ya)力，而且對(dui)電(dian)池的長(chang)期健(jian)康(kang)也有好處。

缺(que)點：缺(que)點非常(chang)明顯，充電時間較長(chang)，僅滿足白(bai)天運作(zuo)，晚上休(xiu)息(xi)的車輛。

二、快(kuai)充(chong)的(de)優缺點

優點：充(chong)電速度快，相當節約時(shi)間(jian)。

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)(chong)(chong)站的(de)(de)充(chong)(chong)(chong)電樁(zhuang)(zhuang)確實(shi)電壓比較高，例如(ru)一(yi)臺240KW的(de)(de)充(chong)(chong)(chong)電樁(zhuang)(zhuang)，它的(de)(de)輸出電壓可以達到750V，電流(liu)可達480A。而慢充(chong)(chong)(chong)的(de)(de)交流(liu)充(chong)(chong)(chong)電樁(zhuang)(zhuang)充(chong)(chong)(chong)電電壓是220v。至于新能源車高壓充(chong)(chong)(chong)電安全(quan)嗎(ma)這個問題，現在(zai)的(de)(de)充(chong)(chong)(chong)電樁(zhuang)(zhuang)都會內置(zhi)漏電保護(hu)(hu)、過(guo)壓保護(hu)(hu)、過(guo)流(liu)保護(hu)(hu)、溫度檢測等功能，所以安全(quan)性還是有保障(zhang)的(de)(de)。
