新能源汽車能改快充嗎

如果新能(neng)源汽(qi)車(che)原(yuan)本(ben)沒有快充(chong)功能(neng)的(de)(de)話是不能(neng)后期加(jia)裝的(de)(de)。因(yin)為(wei)電池的(de)(de)電壓和電容量的(de)(de)原(yuan)因(yin)，后期加(jia)裝對車(che)子的(de)(de)使用很(hen)不好。

第一(yi)是因(yin)為快(kuai)充的(de)電壓很(hen)高，我們的(de)車輛動力電池的(de)容量那(nei)么高。第二是車輛的(de)電控(kong)管理系統不(bu)具(ju)備此功能。第三(san)是線束接口以及整車控(kong)制器(qi)，軟(ruan)件硬件都不(bu)具(ju)備快(kuai)充。所以加(jia)裝的(de)話相當于把(ba)車子換新了。很(hen)不(bu)劃算也(ye)很(hen)難加(jia)裝。

新能源汽車快充和慢充的區別

1、充電(dian)速(su)度(du)不同

新能源汽車快充僅需(xu)要一個(ge)(ge)小時(shi)就可以(yi)將電(dian)(dian)(dian)池充到百分(fen)之八十的電(dian)(dian)(dian)量(liang)；新能(neng)源汽車慢充需(xu)要8到10個(ge)(ge)小時(shi)才(cai)能(neng)將電(dian)(dian)(dian)池電(dian)(dian)(dian)量(liang)完全充滿。

2、接口不同

快速(su)(su)充(chong)電(dian)(dian)接(jie)口中(zhong)間有兩(liang)條母線分(fen)別為電(dian)(dian)源正負，而且在(zai)整個(ge)充(chong)電(dian)(dian)過程(cheng)當中(zhong)電(dian)(dian)流都非常大所以母線也非常粗(cu)。而慢速(su)(su)充(chong)電(dian)(dian)則需要使(shi)用(yong)到零(ling)線火線還有地線三(san)根(gen)母線，所以在(zai)中(zhong)間部(bu)位有三(san)條線，但是(shi)慢速(su)(su)充(chong)電(dian)(dian)需要的(de)電(dian)(dian)流并不(bu)(bu)(bu)高所以接(jie)口也相對(dui)更(geng)細。由于這兩(liang)種充(chong)電(dian)(dian)接(jie)口不(bu)(bu)(bu)同，所以在(zai)充(chong)電(dian)(dian)的(de)時(shi)候如果(guo)選擇(ze)的(de)充(chong)電(dian)(dian)樁(zhuang)和車輛不(bu)(bu)(bu)一致，是(shi)插(cha)不(bu)(bu)(bu)上(shang)去的(de)。

3、充(chong)電原理不同

從(cong)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)原理來看快速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)和慢速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)存在較大(da)差(cha)異，快速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)是直(zhi)(zhi)(zhi)接通(tong)(tong)過(guo)(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)樁(zhuang)本身自帶的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機將工業用電(dian)(dian)(dian)(dian)(dian)(dian)轉換為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車需要(yao)的(de)(de)(de)直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，然后直(zhi)(zhi)(zhi)接通(tong)(tong)過(guo)(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍(qiang)送(song)(song)(song)入動(dong)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。而慢速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)則是直(zhi)(zhi)(zhi)接通(tong)(tong)過(guo)(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)槍(qiang)將220伏的(de)(de)(de)家(jia)用電(dian)(dian)(dian)(dian)(dian)(dian)送(song)(song)(song)入到車載(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機，然后通(tong)(tong)過(guo)(guo)車載(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機再(zai)把220伏的(de)(de)(de)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)轉化(hua)為(wei)車輛(liang)需要(yao)使用的(de)(de)(de)直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)然后再(zai)送(song)(song)(song)入動(dong)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。所以如果想通(tong)(tong)過(guo)(guo)慢速(su)(su)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)接口(kou)將充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)樁(zhuang)的(de)(de)(de)直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)送(song)(song)(song)動(dong)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)這個肯定是不可(ke)能實現的(de)(de)(de)。

4、充電(dian)電(dian)流不同

快速(su)充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)也(ye)叫做(zuo)直(zhi)(zhi)流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)充(chong)電(dian)(dian)(dian)(dian)槍(qiang)輸出為直(zhi)(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)，而且充(chong)電(dian)(dian)(dian)(dian)功率(lv)都要(yao)在(zai)15KW以上(shang)，目前主(zhu)流(liu)(liu)的充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)功率(lv)在(zai)40KW居多。而慢速(su)充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)也(ye)叫做(zuo)交流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)，這種(zhong)充(chong)電(dian)(dian)(dian)(dian)槍(qiang)輸出電(dian)(dian)(dian)(dian)流(liu)(liu)為交流(liu)(liu)電(dian)(dian)(dian)(dian)同時充(chong)電(dian)(dian)(dian)(dian)功率(lv)比較低，常(chang)見的交流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)功率(lv)有3.5KW和(he)7KW兩種(zhong)。所(suo)以想要(yao)直(zhi)(zhi)接(jie)把直(zhi)(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)送入慢充(chong)接(jie)口，強大的電(dian)(dian)(dian)(dian)流(liu)(liu)也(ye)會瞬間燒壞充(chong)電(dian)(dian)(dian)(dian)接(jie)口線(xian)路以及車載充(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(du)給設(she)備電(dian)(dian)池充電(dian)(dian)不(bu)僅(jin)可以減少熱量和(he)電(dian)(dian)池壓力，而且對電(dian)(dian)池的長期健康也有(you)好處。

缺點：缺點非常明顯，充電時間較長，僅滿(man)足(zu)白天運作，晚(wan)上休息的車輛。

二、快充的優(you)缺點(dian)

優點(dian)：充電速度快，相當(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

目前快充(chong)(chong)站的(de)(de)充(chong)(chong)電(dian)(dian)樁確實電(dian)(dian)壓比較高，例如(ru)一臺240KW的(de)(de)充(chong)(chong)電(dian)(dian)樁，它的(de)(de)輸出電(dian)(dian)壓可以達到750V，電(dian)(dian)流可達480A。而慢(man)充(chong)(chong)的(de)(de)交流充(chong)(chong)電(dian)(dian)樁充(chong)(chong)電(dian)(dian)電(dian)(dian)壓是220v。至于新(xin)能源車高壓充(chong)(chong)電(dian)(dian)安全(quan)(quan)嗎這個問題，現(xian)在的(de)(de)充(chong)(chong)電(dian)(dian)樁都(dou)會(hui)內(nei)置漏電(dian)(dian)保(bao)護、過(guo)壓保(bao)護、過(guo)流保(bao)護、溫度檢測等功(gong)能，所以安全(quan)(quan)性還是有保(bao)障的(de)(de)。
