作為電動汽車(che)大(da)規模推廣應用的前提，電(dian)(dian)動(dong)汽車(che)充(chong)(chong)換電(dian)(dian)設施的建設備(bei)受關注。除有線充(chong)(chong)電(dian)(dian)樁外(wai)，分析(xi)人士指出，萬物(wu)互(hu)通互(hu)聯是大(da)勢所(suo)趨，充(chong)(chong)電(dian)(dian)產業(ye)會(hui)向(xiang)無(wu)(wu)線充(chong)(chong)電(dian)(dian)方向(xiang)遷移。隨著無(wu)(wu)線充(chong)(chong)電(dian)(dian)技術的成熟，未來(lai)(lai)支持(chi)無(wu)(wu)線充(chong)(chong)電(dian)(dian)的設備(bei)會(hui)越來(lai)(lai)越多(duo)，電(dian)(dian)動(dong)汽車(che)將成為無(wu)(wu)線充(chong)(chong)電(dian)(dian)設備(bei)應用領域最具潛力(li)的市場。

　　實現(xian)“停車即充電”

　　目(mu)前充電問題對于(yu)新能(neng)(neng)源(yuan)汽車產業發展仍是瓶頸。相比于(yu)有線充電樁的諸多局限，大功率無(wu)線充電技(ji)術可能(neng)(neng)對新能(neng)(neng)源(yuan)汽車產業起(qi)到推動作用。

　　據了解，無線充(chong)電技術主要是通過(guo)非(fei)接觸的(de)電磁感應方式進行(xing)電力(li)傳輸(shu)，通過(guo)埋設于(yu)地表的(de)一次線圈(quan)與固(gu)定(ding)于(yu)車輛底盤(pan)的(de)二次線圈(quan)的(de)電磁耦(ou)合來傳輸(shu)電能(neng)，對(dui)動力(li)電池進行(xing)充(chong)電，具(ju)有安全環保、全自動、免維護(hu)等一系列(lie)優點。

　　電(dian)(dian)(dian)(dian)磁感應式(shi)的優點是(shi)能夠實(shi)現(xian)較大的傳(chuan)輸功率(lv)，傳(chuan)輸效率(lv)可(ke)以達到90%。中興、奔馳、寶(bao)馬等公司(si)采(cai)用電(dian)(dian)(dian)(dian)磁感應式(shi)技術(shu)原(yuan)理研發(fa)無(wu)線(xian)充(chong)電(dian)(dian)(dian)(dian)。據介紹，中興無(wu)線(xian)充(chong)電(dian)(dian)(dian)(dian)技術(shu)源于非(fei)接(jie)觸式(shi)無(wu)線(xian)電(dian)(dian)(dian)(dian)力輸送技術(shu)，通過(guo)非(fei)接(jie)觸的電(dian)(dian)(dian)(dian)磁感應方式(shi)進行(xing)電(dian)(dian)(dian)(dian)力傳(chuan)輸，充(chong)電(dian)(dian)(dian)(dian)車(che)輛在(zai)充(chong)電(dian)(dian)(dian)(dian)停(ting)車(che)位停(ting)泊(bo)后，司(si)機僅需(xu)在(zai)車(che)載PAD或手機客戶(hu)端上點擊“充(chong)電(dian)(dian)(dian)(dian)”按鈕，即可(ke)通過(guo)Wi-Fi自(zi)動(dong)接(jie)入通信網(wang)絡，建立起地面系統(tong)和車(che)載系統(tong)的通路(lu)連接(jie)進行(xing)充(chong)電(dian)(dian)(dian)(dian)，真(zhen)正實(shi)現(xian)“停(ting)車(che)即充(chong)電(dian)(dian)(dian)(dian)”。

　　相(xiang)比于(yu)有線充(chong)電(dian)(dian)(dian)樁占用(yong)土地資源、建樁需與(yu)相(xiang)關部門溝通、建設成本相(xiang)對較高等問題，無線充(chong)電(dian)(dian)(dian)設備占地小、充(chong)電(dian)(dian)(dian)過(guo)程便利性高、大幅改(gai)善充(chong)電(dian)(dian)(dian)站管理和電(dian)(dian)(dian)動車用(yong)戶(hu)體驗，可完(wan)全實(shi)現自動化運營。同(tong)時無線充(chong)電(dian)(dian)(dian)日常運營與(yu)維護經濟(ji)性以及對運行環境(jing)的要求比傳統有線充(chong)電(dian)(dian)(dian)更低。

　　國家能(neng)源(yuan)局副局長鄭柵潔表示，充電(dian)樁國家標(biao)準(zhun)發布以(yi)后(hou)，要(yao)對存(cun)量也就(jiu)是(shi)現有(you)(you)(you)充電(dian)樁進行全(quan)面改(gai)造。另(ling)外也要(yao)加強(qiang)一些新技(ji)術，比(bi)如像無線(xian)充電(dian)標(biao)準(zhun)的研究等。分析(xi)人士指出，這意味(wei)著(zhu)無線(xian)充電(dian)技(ji)術有(you)(you)(you)望被引入到有(you)(you)(you)線(xian)的充電(dian)樁中(zhong)。對無線(xian)充電(dian)類企業而言，這也意味(wei)著(zhu)巨(ju)大的市(shi)場前(qian)景。

　　上(shang)市公司積極布局
