純電(dian)(dian)動(dong)(dong)汽(qi)車(che)(che)，是指以已充滿電(dian)(dian)的(de)蓄電(dian)(dian)池供(gong)電(dian)(dian)給(gei)電(dian)(dian)動(dong)(dong)機，由(you)電(dian)(dian)動(dong)(dong)機推動(dong)(dong)的(de)車(che)(che)輛，而電(dian)(dian)池的(de)電(dian)(dian)量由(you)外(wai)部(bu)電(dian)(dian)源補充，并(bing)且(qie)符合(he)道路交(jiao)通(tong)、安全法規各(ge)項要(yao)求的(de)車(che)(che)輛。

純電動汽車(che)(che)完全由(you)(you)可(ke)充電電池提供動力源(yuan)的汽車(che)(che)，由(you)(you)于(yu)對環境影響相對傳統(tong)汽車(che)(che)較小，其前景被廣泛看(kan)好。

電(dian)動(dong)(dong)汽車(che)的(de)(de)(de)組(zu)成(cheng)包括：電(dian)力驅(qu)動(dong)(dong)及(ji)(ji)控(kong)制(zhi)系(xi)統(tong)、驅(qu)動(dong)(dong)力傳(chuan)動(dong)(dong)等(deng)機械系(xi)統(tong)、完成(cheng)既(ji)定任(ren)務(wu)的(de)(de)(de)工作裝置(zhi)等(deng)。電(dian)力驅(qu)動(dong)(dong)及(ji)(ji)控(kong)制(zhi)系(xi)統(tong)是(shi)電(dian)動(dong)(dong)汽車(che)的(de)(de)(de)核心，也是(shi)區別于內燃機汽車(che)的(de)(de)(de)最(zui)大不同點。電(dian)力驅(qu)動(dong)(dong)及(ji)(ji)控(kong)制(zhi)系(xi)統(tong)由驅(qu)動(dong)(dong)電(dian)動(dong)(dong)機、電(dian)源和電(dian)動(dong)(dong)機的(de)(de)(de)調速控(kong)制(zhi)裝置(zhi)等(deng)組(zu)成(cheng)。電(dian)動(dong)(dong)汽車(che)的(de)(de)(de)其(qi)他裝置(zhi)基本與(yu)內燃機汽車(che)相同。
