感應充(chong)電(dian)器(qi)是(shi)利用高頻(pin)交流磁場的(de)(de)變壓器(qi)原理，將電(dian)能從離車(che)的(de)(de)原方感應到(dao)車(che)載(zai)的(de)(de)副方，以達到(dao)給蓄電(dian)池充(chong)電(dian)的(de)(de)目(mu)的(de)(de)。感應充(chong)電(dian)的(de)(de)最大優點是(shi)安全，這是(shi)因為充(chong)電(dian)器(qi)與(yu)車(che)輛(liang)之間并無(wu)直接的(de)(de)點接觸，即(ji)使(shi)車(che)輛(liang)在(zai)惡劣(lie)的(de)(de)氣候下，如雨(yu)雪(xue)天，進行充(chong)電(dian)也(ye)無(wu)觸電(dian)的(de)(de)危險。

配電箱是按電氣接線要求將開關設備、測量儀表，昆明充電樁保護電器和輔助設備組裝在封閉或半封閉金屬柜中或屏幅上，構成低壓配電箱。充電樁價格正常運行(xing)時(shi)可借(jie)助(zhu)手動或自動開關(guan)接通(tong)或分(fen)斷(duan)電路。故障或不正常運行(xing)時(shi)借(jie)助(zhu)保護電器切斷(duan)電路或報(bao)警(jing)。借(jie)測量儀(yi)表可顯示(shi)運行(xing)中(zhong)的各種參數(shu)，還可對某些電氣參數(shu)進(jin)行(xing)調整，對偏離正常工作(zuo)狀(zhuang)態進(jin)行(xing)提示(shi)或發出信(xin)號。

按照安裝地點(dian)，可分(fen)為(wei)(wei)(wei)公共(gong)充(chong)電(dian)(dian)(dian)(dian)樁和專用充(chong)電(dian)(dian)(dian)(dian)樁。 公共(gong)充(chong)電(dian)(dian)(dian)(dian)樁是(shi)(shi)建(jian)設在(zai)公共(gong)停(ting)(ting)車場(chang)（庫）結合(he)停(ting)(ting)車泊位(wei)，為(wei)(wei)(wei)社會(hui)車輛(liang)提供公共(gong)充(chong)電(dian)(dian)(dian)(dian)服務的充(chong)電(dian)(dian)(dian)(dian)樁。 專用充(chong)電(dian)(dian)(dian)(dian)樁是(shi)(shi)建(jian)設單位(wei)（企業(ye)）自(zi)(zi)有停(ting)(ting)車場(chang)（庫），為(wei)(wei)(wei)單位(wei)（企業(ye)）內部人員(yuan)使用的充(chong)電(dian)(dian)(dian)(dian)樁。 自(zi)(zi)用充(chong)電(dian)(dian)(dian)(dian)樁是(shi)(shi)建(jian)設在(zai)個人自(zi)(zi)有車位(wei)（庫），為(wei)(wei)(wei)私人用戶(hu)提供充(chong)電(dian)(dian)(dian)(dian)的充(chong)電(dian)(dian)(dian)(dian)樁。 充(chong)電(dian)(dian)(dian)(dian)樁一(yi)般(ban)結合(he)停(ting)(ting)車場(chang)（庫）的停(ting)(ting)車位(wei)建(jian)設。安裝在(zai)戶(hu)外的充(chong)電(dian)(dian)(dian)(dian)樁防護(hu)等級不(bu)應低(di)于IP54。安裝在(zai)戶(hu)內的充(chong)電(dian)(dian)(dian)(dian)樁防護(hu)等級不(bu)應低(di)于IP32。
