純電(dian)動(dong)(dong)(dong)汽車(che)，是(shi)指(zhi)以(yi)已充滿電(dian)的(de)蓄電(dian)池(chi)供電(dian)給電(dian)動(dong)(dong)(dong)機(ji)，由電(dian)動(dong)(dong)(dong)機(ji)推動(dong)(dong)(dong)的(de)車(che)輛，而電(dian)池(chi)的(de)電(dian)量由外部電(dian)源(yuan)補充，并且符(fu)合(he)道(dao)路交通、安全法規(gui)各項(xiang)要求的(de)車(che)輛。

純電動汽(qi)車(che)完全由可充電電池提(ti)供動力(li)源的汽(qi)車(che)，由于對環(huan)境影響相對傳(chuan)統汽(qi)車(che)較小，其前景被廣泛看好。

電(dian)動(dong)(dong)(dong)(dong)汽(qi)車的(de)組成包括：電(dian)力(li)驅動(dong)(dong)(dong)(dong)及控(kong)制系(xi)統(tong)(tong)、驅動(dong)(dong)(dong)(dong)力(li)傳動(dong)(dong)(dong)(dong)等機(ji)械系(xi)統(tong)(tong)、完成既(ji)定任務的(de)工作裝置(zhi)等。電(dian)力(li)驅動(dong)(dong)(dong)(dong)及控(kong)制系(xi)統(tong)(tong)是電(dian)動(dong)(dong)(dong)(dong)汽(qi)車的(de)核心，也是區(qu)別于內燃(ran)機(ji)汽(qi)車的(de)最大(da)不同點。電(dian)力(li)驅動(dong)(dong)(dong)(dong)及控(kong)制系(xi)統(tong)(tong)由(you)驅動(dong)(dong)(dong)(dong)電(dian)動(dong)(dong)(dong)(dong)機(ji)、電(dian)源(yuan)和電(dian)動(dong)(dong)(dong)(dong)機(ji)的(de)調(diao)速控(kong)制裝置(zhi)等組成。電(dian)動(dong)(dong)(dong)(dong)汽(qi)車的(de)其他裝置(zhi)基(ji)本(ben)與(yu)內燃(ran)機(ji)汽(qi)車相(xiang)同。
