純電(dian)(dian)動(dong)汽車，是指以已充滿電(dian)(dian)的蓄電(dian)(dian)池供電(dian)(dian)給電(dian)(dian)動(dong)機(ji)，由電(dian)(dian)動(dong)機(ji)推動(dong)的車輛(liang)，而電(dian)(dian)池的電(dian)(dian)量由外部電(dian)(dian)源補充，并且符合道路交通、安全法規各項(xiang)要求的車輛(liang)。

純電(dian)動(dong)汽(qi)車完全由(you)可(ke)充電(dian)電(dian)池提供動(dong)力源(yuan)的汽(qi)車，由(you)于對(dui)環境影響相對(dui)傳統汽(qi)車較小，其前景被廣泛看好。

電(dian)(dian)(dian)動(dong)汽車的組(zu)成(cheng)包括：電(dian)(dian)(dian)力(li)驅(qu)(qu)動(dong)及控(kong)制(zhi)系統(tong)、驅(qu)(qu)動(dong)力(li)傳動(dong)等(deng)機(ji)械系統(tong)、完成(cheng)既(ji)定任務的工(gong)作裝(zhuang)置(zhi)等(deng)。電(dian)(dian)(dian)力(li)驅(qu)(qu)動(dong)及控(kong)制(zhi)系統(tong)是(shi)電(dian)(dian)(dian)動(dong)汽車的核心，也是(shi)區別(bie)于(yu)內燃機(ji)汽車的最大不同(tong)點。電(dian)(dian)(dian)力(li)驅(qu)(qu)動(dong)及控(kong)制(zhi)系統(tong)由(you)驅(qu)(qu)動(dong)電(dian)(dian)(dian)動(dong)機(ji)、電(dian)(dian)(dian)源和電(dian)(dian)(dian)動(dong)機(ji)的調速控(kong)制(zhi)裝(zhuang)置(zhi)等(deng)組(zu)成(cheng)。電(dian)(dian)(dian)動(dong)汽車的其他裝(zhuang)置(zhi)基本(ben)與內燃機(ji)汽車相同(tong)。
