純電(dian)(dian)(dian)動(dong)汽車(che)，是指以已充滿電(dian)(dian)(dian)的蓄(xu)電(dian)(dian)(dian)池(chi)供(gong)電(dian)(dian)(dian)給電(dian)(dian)(dian)動(dong)機，由電(dian)(dian)(dian)動(dong)機推動(dong)的車(che)輛，而電(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)量(liang)由外部電(dian)(dian)(dian)源補充，并且符合道路交通、安全(quan)法(fa)規各項(xiang)要求的車(che)輛。

純電(dian)(dian)動汽車(che)完全由可充電(dian)(dian)電(dian)(dian)池(chi)提供動力源(yuan)的汽車(che)，由于對(dui)環境影響(xiang)相對(dui)傳統汽車(che)較小，其前景被廣泛看好(hao)。

電動(dong)(dong)(dong)(dong)汽車(che)的組(zu)成(cheng)包括(kuo)：電力(li)驅(qu)動(dong)(dong)(dong)(dong)及控(kong)制(zhi)系(xi)(xi)統(tong)(tong)、驅(qu)動(dong)(dong)(dong)(dong)力(li)傳動(dong)(dong)(dong)(dong)等機(ji)械系(xi)(xi)統(tong)(tong)、完成(cheng)既定(ding)任務的工作裝置等。電力(li)驅(qu)動(dong)(dong)(dong)(dong)及控(kong)制(zhi)系(xi)(xi)統(tong)(tong)是(shi)電動(dong)(dong)(dong)(dong)汽車(che)的核心，也是(shi)區別于(yu)內燃(ran)機(ji)汽車(che)的最(zui)大不同點。電力(li)驅(qu)動(dong)(dong)(dong)(dong)及控(kong)制(zhi)系(xi)(xi)統(tong)(tong)由驅(qu)動(dong)(dong)(dong)(dong)電動(dong)(dong)(dong)(dong)機(ji)、電源和(he)電動(dong)(dong)(dong)(dong)機(ji)的調速控(kong)制(zhi)裝置等組(zu)成(cheng)。電動(dong)(dong)(dong)(dong)汽車(che)的其他裝置基(ji)本(ben)與內燃(ran)機(ji)汽車(che)相同。
