新能源汽車如今在國家及政府的支持下飛速發展，購買新能源汽車的人越來越多，充電樁作為新能源汽車一個重要的基礎配套設施，也因此發展迅猛，目前中國充電基礎設施公共類充電設施保有量為全球一。但是，你知道什么是充電樁嗎?你了解它嗎?云南充電樁廠家整(zheng)理了充電(dian)樁的一(yi)(yi)些相關(guan)知(zhi)識，今天就跟著小(xiao)編(bian)一(yi)(yi)起來了解一(yi)(yi)下(xia)。

什(shen)么是充電樁?

充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)，顧名思義(yi)，就是用來給我(wo)們的(de)(de)電(dian)(dian)(dian)動汽(qi)車(che)充(chong)(chong)電(dian)(dian)(dian)用的(de)(de)，它的(de)(de)作用就像加油站里給燃油車(che)加油的(de)(de)加油機。充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)既(ji)可以(yi)(yi)固(gu)定(ding)在地面(mian)，也可以(yi)(yi)固(gu)定(ding)在墻壁上(shang)，安(an)裝在各(ge)大(da)公共空間(jian)、住(zhu)宅小區以(yi)(yi)及充(chong)(chong)電(dian)(dian)(dian)站內(nei)，然后根據不同的(de)(de)電(dian)(dian)(dian)壓(ya)等(deng)(deng)(deng)級為各(ge)種型(xing)號的(de)(de)電(dian)(dian)(dian)動汽(qi)車(che)充(chong)(chong)電(dian)(dian)(dian)。人們可以(yi)(yi)使用特定(ding)的(de)(de)充(chong)(chong)電(dian)(dian)(dian)卡在充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)提供(gong)的(de)(de)人機交互操作界面(mian)上(shang)刷卡使用，進行(xing)相應的(de)(de)充(chong)(chong)電(dian)(dian)(dian)方式(shi)、充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)、費(fei)用數(shu)據打(da)印等(deng)(deng)(deng)操作，充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)顯示(shi)屏能顯示(shi)充(chong)(chong)電(dian)(dian)(dian)量、費(fei)用、充(chong)(chong)電(dian)(dian)(dian)時(shi)間(jian)等(deng)(deng)(deng)數(shu)據。

充(chong)電樁如何(he)進行充(chong)電?

用(yong)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)樁為電(dian)(dian)(dian)(dian)(dian)動汽車充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，實際上就是(shi)為電(dian)(dian)(dian)(dian)(dian)動汽車中的(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)原理是(shi)蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)放電(dian)(dian)(dian)(dian)(dian)后，用(yong)直流(liu)電(dian)(dian)(dian)(dian)(dian)按與放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)相(xiang)反的(de)方向通過蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，使它恢復(fu)工作能(neng)力，這個過程(cheng)稱為蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。蓄(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)正極與電(dian)(dian)(dian)(dian)(dian)源正極相(xiang)聯，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)負極與電(dian)(dian)(dian)(dian)(dian)源負極相(xiang)聯，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓必須(xu)高于電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)總(zong)電(dian)(dian)(dian)(dian)(dian)動勢。一般(ban)來說(shuo)，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)樁有兩種充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)方式(shi)，分別(bie)是(shi)恒流(liu)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)和恒壓充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。在5月1號實施的新版電動汽車術語中，分別對這兩種充電方式進行了定義：恒流充電，以一個受控的恒定電流給蓄電池進行充電的方式;恒壓充電，以一個受控的恒定電壓給蓄電池進行充電的方式。那么恒流充電和恒壓充電具體是什么呢?以下是云南充電樁廠家了解(jie)到(dao)對這兩(liang)種充電方式較為詳細的解(jie)釋。

恒流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)法(fa)：恒流(liu)(liu)充(chong)(chong)(chong)電(dian)(dian)法(fa)是(shi)(shi)用(yong)調整充(chong)(chong)(chong)電(dian)(dian)裝置輸出(chu)電(dian)(dian)壓或(huo)改變與蓄電(dian)(dian)池串聯電(dian)(dian)阻的方法(fa)，保持充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)強度不變的充(chong)(chong)(chong)電(dian)(dian)方法(fa)。控制方法(fa)簡單，但由于(yu)電(dian)(dian)池的可接受電(dian)(dian)流(liu)(liu)能(neng)力是(shi)(shi)隨著充(chong)(chong)(chong)電(dian)(dian)過(guo)程(cheng)的進行(xing)而逐漸下(xia)降(jiang)的，到(dao)充(chong)(chong)(chong)電(dian)(dian)后期，充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)(liu)多用(yong)于(yu)電(dian)(dian)解(jie)水，產(chan)生氣(qi)體，使出(chu)氣(qi)過(guo)甚，因此，常選(xuan)用(yong)階(jie)段充(chong)(chong)(chong)電(dian)(dian)法(fa)。

恒壓(ya)(ya)充(chong)(chong)電(dian)法：充(chong)(chong)電(dian)電(dian)源(yuan)的(de)(de)(de)電(dian)壓(ya)(ya)在全(quan)部(bu)充(chong)(chong)電(dian)時(shi)間里(li)保持恒定的(de)(de)(de)數值，隨著(zhu)蓄電(dian)池(chi)端電(dian)壓(ya)(ya)的(de)(de)(de)逐(zhu)漸升高，電(dian)流(liu)(liu)逐(zhu)漸減(jian)(jian)少。與恒流(liu)(liu)充(chong)(chong)電(dian)法相比，其(qi)充(chong)(chong)電(dian)過程(cheng)更接近(jin)于佳充(chong)(chong)電(dian)曲線。用恒定電(dian)壓(ya)(ya)快速充(chong)(chong)電(dian)。由于充(chong)(chong)電(dian)初期蓄電(dian)池(chi)電(dian)動勢較低，充(chong)(chong)電(dian)電(dian)流(liu)(liu)很大，隨著(zhu)充(chong)(chong)電(dian)的(de)(de)(de)進行，電(dian)流(liu)(liu)將(jiang)逐(zhu)漸減(jian)(jian)少，因(yin)此，云(yun)南充電樁廠家只(zhi)需(xu)簡(jian)易(yi)控制(zhi)系統。
