電(dian)(dian)(dian)(dian)動(dong)汽車(che)(che)交(jiao)(jiao)(jiao)(jiao)(jiao)流充(chong)(chong)電(dian)(dian)(dian)(dian)樁，俗稱(cheng)就是“慢充(chong)(chong)”，固定安裝(zhuang)在電(dian)(dian)(dian)(dian)動(dong)汽車(che)(che)外(wai)、與交(jiao)(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)(dian)(dian)網(wang)連接，為電(dian)(dian)(dian)(dian)動(dong)汽車(che)(che)車(che)(che)載(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)機（即固定安裝(zhuang)在電(dian)(dian)(dian)(dian)動(dong)汽車(che)(che)上的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)機）提(ti)供(gong)交(jiao)(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)(dian)(dian)源的(de)(de)供(gong)電(dian)(dian)(dian)(dian)裝(zhuang)置。交(jiao)(jiao)(jiao)(jiao)(jiao)流充(chong)(chong)電(dian)(dian)(dian)(dian)樁只提(ti)供(gong)電(dian)(dian)(dian)(dian)力輸出，沒有充(chong)(chong)電(dian)(dian)(dian)(dian)功能，需連接車(che)(che)載(zai)充(chong)(chong)電(dian)(dian)(dian)(dian)機為電(dian)(dian)(dian)(dian)動(dong)汽車(che)(che)充(chong)(chong)電(dian)(dian)(dian)(dian)。相當(dang)于(yu)只是起了一(yi)個(ge)控制電(dian)(dian)(dian)(dian)源的(de)(de)作(zuo)用的(de)(de)。交(jiao)(jiao)(jiao)(jiao)(jiao)流充(chong)(chong)電(dian)(dian)(dian)(dian)樁原理是什(shen)么(me)(me)？交(jiao)(jiao)(jiao)(jiao)(jiao)流充(chong)(chong)電(dian)(dian)(dian)(dian)樁結構是怎么(me)(me)樣(yang)的(de)(de)？
交(jiao)流充電(dian)樁原理(li)
交流(liu)(liu)充電樁，本質就是一個帶控制的插(cha)座，輸出(chu)的是交流(liu)(liu)單相電（家(jia)用220伏），需要車載充電機自己進行變壓整流(liu)(liu)，受限于(yu)車載充電機功(gong)率，一般功(gong)率小(xiao)，3.3kw和7kw的居多。

交流(liu)充電(dian)樁功能特(te)點(dian)

(1)人(ren)機交互(hu)界面采用大屏(ping)幕LCD彩色觸摸屏(ping)，充電(dian)(dian)可選(xuan)擇定(ding)電(dian)(dian)量、定(ding)時間、定(ding)金額、自(zi)動（充滿為止）4種模式；顯示(shi)當(dang)前充電(dian)(dian)模式、時間（已充電(dian)(dian)時間、剩余充電(dian)(dian)時間）、電(dian)(dian)量（已充電(dian)電(dian)量(liang)(liang)、待充(chong)電(dian)電(dian)量(liang)(liang)）及當前計費信息。

（2）、支持(chi)刷卡、掃碼(ma)等多種支付方(fang)式。

（3）、滿足GB/T 20234.1-2015，GB/T 20234.2-2015，GB/T 18487.1-2015 等標準。

（4）、觸摸彩屏顯示，人機(ji)界面友(you)好，易操作、易維護。

（5）、通信(xin)接口豐富，兼容(rong)所有車輛BMS 協議及充(chong)電后臺(tai)協議。

（6）、保(bao)(bao)護(hu)功能完善(shan)：過壓保(bao)(bao)護(hu)，欠(qian)壓保(bao)(bao)護(hu)，過載保(bao)(bao)護(hu)，短路(lu)保(bao)(bao)護(hu)，漏電保(bao)(bao)護(hu)等。
 
 除(chu)以(yi)上特(te)點外(wai)，一般家用簡單的交流充電樁可以(yi)即插(cha)即充或刷卡啟動可不(bu)計費充電等操作方(fang)便。

直流(liu)充電樁(zhuang)和交流(liu)充電樁(zhuang)的區(qu)別

直(zhi)流(liu)充(chong)電(dian)樁：直(zhi)流(liu)電(dian)動(dong)(dong)(dong)汽(qi)車充(chong)電(dian)站，俗稱就是“快充(chong)”，它是固定安裝在電(dian)動(dong)(dong)(dong)汽(qi)車外，與交流(liu)電(dian)網連接，可以為非車載電(dian)動(dong)(dong)(dong)汽(qi)車動(dong)(dong)(dong)力(li)電(dian)池提供直(zhi)流(liu)電(dian)源的供電(dian)裝置。直(zhi)流(liu)充(chong)電(dian)樁的輸入(ru)電(dian)壓采(cai)用三相五線AC380V±15%，頻率50Hz,輸出為可(ke)調(diao)直(zhi)流電(dian)(dian)(dian)，直(zhi)接為電(dian)(dian)(dian)動汽車的(de)動力電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)。由于直(zhi)流充(chong)電(dian)(dian)(dian)樁采(cai)用三相五線制供(gong)(gong)電(dian)(dian)(dian)，可(ke)以提供(gong)(gong)足夠的(de)功(gong)率，輸出的(de)電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流調(diao)整范圍

大，可以實現快充的要求。
交(jiao)(jiao)(jiao)(jiao)流充(chong)(chong)電(dian)(dian)樁：交(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)動(dong)汽車(che)充(chong)(chong)電(dian)(dian)樁，俗稱(cheng)就是“慢充(chong)(chong)”，固定安裝(zhuang)在電(dian)(dian)動(dong)汽車(che)外(wai)、與交(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)網連接，為電(dian)(dian)動(dong)汽車(che)車(che)載充(chong)(chong)電(dian)(dian)機(即(ji)固定安裝(zhuang)在電(dian)(dian)動(dong)汽車(che)上的(de)充(chong)(chong)電(dian)(dian)機)提(ti)供交(jiao)(jiao)(jiao)(jiao)流電(dian)(dian)源的(de)供電(dian)(dian)裝(zhuang)置。交流充電(dian)樁只提供電(dian)力輸出，沒有充電(dian)功能，需連接車載充電(dian)機為電(dian)動(dong)汽車充電(dian)。相當(dang)于只是起了一個(ge)控制電(dian)源的作(zuo)用(yong)的。

兩者(zhe)的區別(bie)：簡單來說，交(jiao)流充(chong)電(dian)樁(zhuang)需(xu)要(yao)借助車載充(chong)電(dian)機(ji)來充(chong)電(dian)，直流快(kuai)速充(chong)電(dian)樁(zhuang)不需(xu)要(yao)這個設(she)備。二者(zhe)在(zai)充(chong)電(dian)速度上差別(bie)較大(da)，一輛純(chun)電(dian)動汽車(普通(tong)電(dian)池容量)完(wan)全(quan)放電(dian)后通(tong)過7KW交(jiao)流(liu)充(chong)(chong)電(dian)(dian)樁充(chong)(chong)滿(man)需要8個小時左(zuo)右，而通過(guo)直(zhi)流(liu)快(kuai)速(su)充(chong)(chong)電(dian)(dian)樁僅(jin)需要1個小時左(zuo)右。交流(liu)充(chong)(chong)電(dian)(dian)樁給電(dian)(dian)動汽車(che)的充(chong)(chong)電(dian)(dian)機提供電(dian)(dian)力(li)輸入，由于車(che)載充(chong)(chong)電(dian)(dian)機的功率(lv)并不(bu)大，所以不(bu)能實現快(kuai)速(su)充(chong)(chong)電(dian)(dian)。
