根據對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)車(che)(che)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時能量轉換(huan)的方式不同(tong)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)裝置(zhi)可以分(fen)為接(jie)觸式和感(gan)(gan)應(ying)式。隨(sui)著電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)子技術和變(bian)(bian)流(liu)控制技術的飛速(su)發展，高(gao)(gao)精度可控變(bian)(bian)流(liu)技術的成熟和普(pu)及，分(fen)階段恒流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)模(mo)式已經(jing)基本被充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓連續(xu)變(bian)(bian)化的恒壓限流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)模(mo)式取代。新型的電(dian)(dian)(dian)(dian)(dian)(dian)動汽(qi)車(che)(che)感(gan)(gan)應(ying)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)技術發展很快。感(gan)(gan)應(ying)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是利用(yong)高(gao)(gao)頻交流(liu)磁場(chang)的變(bian)(bian)壓器(qi)原理，將電(dian)(dian)(dian)(dian)(dian)(dian)能從離車(che)(che)的原方感(gan)(gan)應(ying)到車(che)(che)載的副方，以達到給(gei)蓄電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的目的。感(gan)(gan)應(ying)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的優點(dian)是安全，這是因為充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)與車(che)(che)輛之(zhi)間并(bing)無(wu)直接(jie)的點(dian)接(jie)觸，即使(shi)車(che)(che)輛在惡劣(lie)的氣候下，如雨雪(xue)天(tian)，進行充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)也無(wu)觸電(dian)(dian)(dian)(dian)(dian)(dian)的危險。

接觸式(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)問題在(zai)(zai)(zai)于它的(de)(de)(de)安全(quan)性(xing)和通(tong)用(yong)性(xing)。為(wei)了使它滿足嚴格的(de)(de)(de)安全(quan)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)標準，必須在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)路(lu)上采用(yong)許多措(cuo)施使充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)設(she)備能夠在(zai)(zai)(zai)各種環境(jing)下安全(quan)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，恒壓(ya)限(xian)流充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)和分階段恒流充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)均屬于接觸式(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)技術。新型(xing)的(de)(de)(de)電(dian)(dian)(dian)(dian)動汽車(che)(che)(che)感應(ying)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)技術發展很快。感應(ying)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器是利用(yong)高頻交流磁場的(de)(de)(de)變(bian)壓(ya)器原理，將電(dian)(dian)(dian)(dian)能從離車(che)(che)(che)的(de)(de)(de)原方(fang)感應(ying)到車(che)(che)(che)載的(de)(de)(de)副方(fang)，以達到給(gei)蓄電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)目的(de)(de)(de)。感應(ying)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)優點是安全(quan)，這是因(yin)為(wei)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器與(yu)車(che)(che)(che)輛(liang)之間并無直接的(de)(de)(de)點接觸，即使車(che)(che)(che)輛(liang)在(zai)(zai)(zai)惡(e)劣的(de)(de)(de)氣候下，如雨雪天，進(jin)行充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)也無觸電(dian)(dian)(dian)(dian)的(de)(de)(de)危險。

一(yi)般多(duo)(duo)管(guan)的交流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)使用(yong)16A的220V進(jin)線(xian)(xian)(xian)(xian)，零線(xian)(xian)(xian)(xian)、火(huo)線(xian)(xian)(xian)(xian)、地線(xian)(xian)(xian)(xian)三根即可(ke)，小區很多(duo)(duo)配電(dian)(dian)(dian)柜都具備這種安(an)裝條(tiao)件，單(dan)管(guan)的汽(qi)車充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)使用(yong)10平方的主(zhu)線(xian)(xian)(xian)(xian)即可(ke)，這也是交流(liu)充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)目(mu)前(qian)受歡迎的原因。今后電(dian)(dian)(dian)動汽(qi)車的規模(mo)進(jin)一(yi)步(bu)增大，充(chong)(chong)電(dian)(dian)(dian)樁(zhuang)(zhuang)附近，如果多(duo)(duo)臺直流(liu)大功(gong)率樁(zhuang)(zhuang)同時(shi)充(chong)(chong)電(dian)(dian)(dian)，對電(dian)(dian)(dian)網的壓力就(jiu)會增大，這也是要考慮的問題。機(ji)車蓄電(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)機(ji)工作時(shi)無需人工值守，超長時(shi)間充(chong)(chong)電(dian)(dian)(dian)，無過充(chong)(chong)危(wei)險。
