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7kw的居多(duo)。

交流充電樁功能特點

(1)人機交互界面采用大屏幕LCD彩(cai)色觸摸屏，充電可選擇定(ding)(ding)電量、定(ding)(ding)時間、定(ding)(ding)金(jin)額、自(zi)動（充滿為止）4種模式(shi)；顯(xian)示當前(qian)(qian)充(chong)電(dian)模式(shi)、時間(jian)（已充(chong)電(dian)時間(jian)、剩余(yu)充(chong)電(dian)時間(jian)）、電(dian)量（已充(chong)電(dian)電(dian)量、待充(chong)電(dian)電(dian)量）及當前(qian)(qian)計費信(xin)息。

(2)讀卡器(qi)用(yong)于身份識別、記(ji)錄電(dian)量消費信息。打印機用(yong)于消費票據(ju)打印。

(3)完備的安全(quan)防護措施。

1)緊急停止充電按鈕。

2)輸出過電(dian)流保護功(gong)能。

3)輸出漏電保護功能。

4)自動(dong)判(pan)斷充(chong)電(dian)(dian)(dian)連(lian)接器、充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)纜是否正(zheng)確(que)連(lian)接。當交(jiao)流充(chong)電(dian)(dian)(dian)樁(zhuang)與電(dian)(dian)(dian)動(dong)汽車正(zheng)確(que)連(lian)接后(hou)，充(chong)電(dian)(dian)(dian)樁(zhuang)才能允許啟動(dong)充(chong)電(dian)(dian)(dian)過程(cheng)；當交(jiao)流充(chong)電(dian)(dian)(dian)樁(zhuang)檢測到(dao)與電(dian)(dian)(dian)動(dong)汽車連(lian)接不正(zheng)常(chang)時，立即停(ting)止充(chong)電(dian)(dian)(dian)。

5)具有阻燃功能(neng)。

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(pin)率(lv)50Hz,輸(shu)出為可(ke)調直(zhi)流(liu)(liu)電(dian)，直(zhi)接為電(dian)動汽車的(de)動力電(dian)池充(chong)電(dian)。由(you)于(yu)直(zhi)流(liu)(liu)充(chong)電(dian)樁采用三相(xiang)四線制(zhi)供電(dian)，可(ke)以(yi)提供足夠的(de)功率，輸(shu)出的(de)電(dian)壓和電(dian)流(liu)(liu)調整范圍大，可(ke)以(yi)實現快充(chong)的(de)要(yao)求。

交(jiao)流充電樁：交(jiao)流電動汽車充電樁，俗稱就(jiu)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(即固定(ding)安裝在電動汽車上的(de)充(chong)電機)提供交(jiao)流電(dian)(dian)(dian)源的供電(dian)(dian)(dian)裝置。交(jiao)流充(chong)電(dian)(dian)(dian)樁只提供電(dian)(dian)(dian)力輸出(chu)，沒有(you)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(dang)于只是(shi)起了一個控(kong)制電(dian)(dian)(dian)源的作用的。

兩(liang)者(zhe)的區別：簡(jian)單來說，交流(liu)充電(dian)(dian)(dian)(dian)(dian)樁需(xu)要借助(zhu)車載充電(dian)(dian)(dian)(dian)(dian)機來充電(dian)(dian)(dian)(dian)(dian)，直流(liu)快(kuai)速充電(dian)(dian)(dian)(dian)(dian)樁不(bu)需(xu)要這個設(she)備(bei)。二者(zhe)在充電(dian)(dian)(dian)(dian)(dian)速度上差別較大，一輛純電(dian)(dian)(dian)(dian)(dian)動汽車(普(pu)通電(dian)池容量(liang))完全放電(dian)后通(tong)過交(jiao)流充(chong)電(dian)樁充(chong)滿需要8個小時，而通過直(zhi)流快(kuai)速充電樁僅需要2到3個小時。交流充(chong)電(dian)樁(zhuang)給電(dian)動汽(qi)車的充(chong)電(dian)機提供(gong)電(dian)力(li)輸入，由于(yu)車載充(chong)電(dian)機的功率(lv)并不(bu)大，所以不(bu)能實現快(kuai)速(su)充(chong)電(dian)。
