純電(dian)(dian)動汽車(che)，是指以已充滿電(dian)(dian)的(de)蓄電(dian)(dian)池供電(dian)(dian)給(gei)電(dian)(dian)動機，由電(dian)(dian)動機推(tui)動的(de)車(che)輛，而電(dian)(dian)池的(de)電(dian)(dian)量由外(wai)部(bu)電(dian)(dian)源(yuan)補充，并且符合道路交(jiao)通(tong)、安全法規各(ge)項要求的(de)車(che)輛。

純電(dian)動汽(qi)車(che)(che)完全由可(ke)充(chong)電(dian)電(dian)池(chi)提供動力源(yuan)的汽(qi)車(che)(che)，由于對環境影響相(xiang)對傳統汽(qi)車(che)(che)較小，其前景被廣(guang)泛(fan)看好(hao)。

電(dian)(dian)動(dong)(dong)(dong)汽車(che)(che)的組(zu)成(cheng)包括：電(dian)(dian)力驅(qu)(qu)動(dong)(dong)(dong)及控制系(xi)統(tong)、驅(qu)(qu)動(dong)(dong)(dong)力傳動(dong)(dong)(dong)等機械系(xi)統(tong)、完成(cheng)既定任務的工作裝置(zhi)等。電(dian)(dian)力驅(qu)(qu)動(dong)(dong)(dong)及控制系(xi)統(tong)是(shi)電(dian)(dian)動(dong)(dong)(dong)汽車(che)(che)的核心，也是(shi)區別于內燃機汽車(che)(che)的最(zui)大不同點。電(dian)(dian)力驅(qu)(qu)動(dong)(dong)(dong)及控制系(xi)統(tong)由驅(qu)(qu)動(dong)(dong)(dong)電(dian)(dian)動(dong)(dong)(dong)機、電(dian)(dian)源和電(dian)(dian)動(dong)(dong)(dong)機的調速控制裝置(zhi)等組(zu)成(cheng)。電(dian)(dian)動(dong)(dong)(dong)汽車(che)(che)的其他裝置(zhi)基本與內燃機汽車(che)(che)相同。
