交流充電樁原理

交流充電樁，本質就是一個帶控制的插座，輸出的是交流電，需要車載充電機自己進行變壓整流，受限于車載充電機功率，一般功率小，3.3和(he)7kw的居(ju)多。

交流充電樁功能特點

(1)人機交互界面采用大屏幕(mu)LCD彩色觸摸屏，充(chong)電可(ke)選擇(ze)定電量、定時間(jian)、定金(jin)額、自(zi)動（充(chong)滿為(wei)止）4種(zhong)模(mo)式；顯示(shi)當(dang)前充(chong)電(dian)(dian)模(mo)式、時間（已(yi)(yi)充(chong)電(dian)(dian)時間、剩余充(chong)電(dian)(dian)時間）、電(dian)(dian)量（已(yi)(yi)充(chong)電(dian)(dian)電(dian)(dian)量、待充(chong)電(dian)(dian)電(dian)(dian)量）及當(dang)前計(ji)費信息。

(2)讀卡(ka)器(qi)用于身份識別、記(ji)錄電量消費信息(xi)。打(da)印(yin)機用于消費票據打(da)印(yin)。

(3)完(wan)備的安全防護措(cuo)施(shi)。

4)自動判斷充(chong)(chong)(chong)電(dian)(dian)(dian)連(lian)(lian)接器、充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)纜是否正(zheng)確連(lian)(lian)接。當(dang)交流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)樁與電(dian)(dian)(dian)動汽車(che)正(zheng)確連(lian)(lian)接后，充(chong)(chong)(chong)電(dian)(dian)(dian)樁才(cai)能允(yun)許啟動充(chong)(chong)(chong)電(dian)(dian)(dian)過程；當(dang)交流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)樁檢測(ce)到與電(dian)(dian)(dian)動汽車(che)連(lian)(lian)接不正(zheng)常時，立即停止充(chong)(chong)(chong)電(dian)(dian)(dian)。

5)具有(you)阻燃(ran)功能。

直流充電樁和交流充電樁的區別

直流充電樁：直流電動汽車充電站，俗稱就是“快充”，它是固定安裝在電動汽車外，與交流電網連接，可以為非車載電動汽車動力電池提供直流電源的供電裝置。直流充電樁的輸入電壓采用三相四線AC380V±15%，頻率50Hz,輸出(chu)為可調直流電(dian)(dian)(dian)，直接為電(dian)(dian)(dian)動汽車的(de)動力(li)電(dian)(dian)(dian)池充電(dian)(dian)(dian)。由于直流充電(dian)(dian)(dian)樁采用(yong)三(san)相四線制供電(dian)(dian)(dian)，可以提供足夠(gou)的(de)功率(lv)，輸出(chu)的(de)電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流調整范圍(wei)大，可以實現快充的(de)要(yao)求。

交(jiao)(jiao)流充(chong)電(dian)樁：交(jiao)(jiao)流電(dian)動汽車充(chong)電(dian)樁，俗稱(cheng)就是“慢充”，固定安裝在電動汽車外、與交流電網連接，為電動汽車車載充電機(即(ji)固定(ding)安裝在(zai)電動(dong)汽(qi)車上的充電機)提供交流(liu)電(dian)(dian)(dian)源的供電(dian)(dian)(dian)裝置。交流(liu)充(chong)電(dian)(dian)(dian)樁只(zhi)提供電(dian)(dian)(dian)力輸出，沒有充(chong)電(dian)(dian)(dian)功(gong)能(neng)，需連接車載充(chong)電(dian)(dian)(dian)機(ji)為電(dian)(dian)(dian)動汽車充(chong)電(dian)(dian)(dian)。相當于只(zhi)是(shi)起了一個控(kong)制(zhi)電(dian)(dian)(dian)源的作(zuo)用的。

兩者的區別：簡單來說，交流(liu)充(chong)(chong)電(dian)樁(zhuang)需要借助(zhu)車載充(chong)(chong)電(dian)機來充(chong)(chong)電(dian)，直流(liu)快速(su)充(chong)(chong)電(dian)樁(zhuang)不需要這個設備。二者在(zai)充(chong)(chong)電(dian)速(su)度上差別較大，一輛純電(dian)動汽(qi)車(普通電池(chi)容(rong)量)完全放電后通(tong)過交流充電樁充滿需要8個(ge)小時，而通過直流快速充電(dian)樁(zhuang)僅(jin)需要2到(dao)3個小時。交流充(chong)電(dian)樁(zhuang)給電(dian)動汽車的充(chong)電(dian)機提供(gong)電(dian)力輸入，由于車載充(chong)電(dian)機的功率(lv)并不(bu)大(da)，所以(yi)不(bu)能實現(xian)快(kuai)速充(chong)電(dian)。
