電動汽車充電樁（栓）的控制電路主要由嵌入式ARM處理器完成，曲靖直流充電樁用戶可自助刷卡進行用戶鑒權、余額查詢、計費查詢等功能，也可提供語音輸出接口，實現語音交互。直流充電樁哪家好用戶可(ke)根據(ju)液(ye)晶顯示屏指示選(xuan)擇(ze)4種充電(dian)模式：包括按(an)時計費充電(dian)、按(an)電(dian)量充電(dian)、自動(dong)充滿、按(an)里程充電(dian)等(deng)

充電(dian)(dian)(dian)(dian)樁建設的全面(mian)開展，無疑會提供巨大(da)(da)(da)的市場。北(bei)上廣(guang)這(zhe)三(san)大(da)(da)(da)城市，由(you)于(yu)交通(tong)擁堵，紛紛通(tong)過車(che)(che)(che)牌進行購車(che)(che)(che)限制。不過由(you)于(yu)電(dian)(dian)(dian)(dian)動車(che)(che)(che)的環(huan)保作用(yong)，政府從上層支持電(dian)(dian)(dian)(dian)動車(che)(che)(che)，因此(ci)北(bei)上廣(guang)等大(da)(da)(da)城市都有相(xiang)關(guan)政策，進入其相(xiang)關(guan)名(ming)錄的電(dian)(dian)(dian)(dian)動車(che)(che)(che)可(ke)以直接獲得車(che)(che)(che)牌，這(zhe)一(yi)點從政策方(fang)面(mian)刺激(ji)了電(dian)(dian)(dian)(dian)動車(che)(che)(che)的需(xu)求。同時(shi)，國內成(cheng)品油(you)價格(ge)上漲速度高于(yu)下降(jiang)速度，最終(zhong)車(che)(che)(che)主(zhu)承(cheng)受的是(shi)越(yue)來(lai)越(yue)高的油(you)價，電(dian)(dian)(dian)(dian)動車(che)(che)(che)可(ke)以代替部(bu)分汽油(you)柴油(you)的消耗，降(jiang)低了這(zhe)部(bu)分成(cheng)本。毋庸置疑充電(dian)(dian)(dian)(dian)樁是(shi)新能(neng)源戰略推(tui)進的終(zhong)端市場，如(ru)能(neng)在(zai)現在(zai)搶占(zhan)先(xian)機，對資本的盈利有極(ji)大(da)(da)(da)好處。
