    對新能(neng)源電(dian)動(dong)車而言，有(you)一個至(zhi)關重要的(de)“三(san)大件”，那(nei)就是(shi)我們常聽(ting)到的(de)三(san)電(dian)系統，這是(shi)電(dian)動(dong)車非(fei)常核心(xin)的(de)部分，包括電(dian)池、電(dian)機(ji)和電(dian)控(kong)系統。調查顯(xian)示，消費者在購買新能(neng)源電(dian)動(dong)車時最先(xian)考慮的(de)因素是(shi)續(xu)航，其次才(cai)是(shi)性能(neng)、設計等因素。

    電(dian)(dian)(dian)(dian)池(chi)對于(yu)新能(neng)源(yuan)電(dian)(dian)(dian)(dian)動(dong)車而言，就相當于(yu)傳統汽車里(li)面的油箱。只(zhi)要(yao)是靠(kao)電(dian)(dian)(dian)(dian)來(lai)驅(qu)動(dong)的載物(wu)，電(dian)(dian)(dian)(dian)池(chi)容量(liang)(liang)越(yue)大，續航能(neng)力自然(ran)就越(yue)強。有的車企(qi)通過(guo)增加(jia)電(dian)(dian)(dian)(dian)池(chi)尺寸(cun)和電(dian)(dian)(dian)(dian)池(chi)數(shu)量(liang)(liang)來(lai)達到(dao)電(dian)(dian)(dian)(dian)流擴容的效果，但以車身結構來(lai)說，越(yue)多(duo)的電(dian)(dian)(dian)(dian)池(chi)意味(wei)著占(zhan)據(ju)的物(wu)理空間越(yue)大，而電(dian)(dian)(dian)(dian)動(dong)汽車的風阻系數(shu)每增加(jia)0.01cd，續航里(li)程將會減少5公里(li)以上，其次電(dian)(dian)(dian)(dian)池(chi)重量(liang)(liang)也是制約電(dian)(dian)(dian)(dian)池(chi)容量(liang)(liang)的重要(yao)因素(su)。

    電(dian)(dian)控(kong)系(xi)統(tong)相當于電(dian)(dian)腦的(de)操作(zuo)系(xi)統(tong)，對新能源電(dian)(dian)動(dong)車的(de)電(dian)(dian)池(chi)(chi)進行監控(kong)和(he)管理，讓電(dian)(dian)池(chi)(chi)保持在最佳狀態(tai)下(xia)工作(zuo)，發揮電(dian)(dian)池(chi)(chi)最大性能。而一套好的(de)電(dian)(dian)控(kong)系(xi)統(tong)，不僅能防(fang)止電(dian)(dian)動(dong)車過(guo)度(du)充電(dian)(dian)、放電(dian)(dian)，還(huan)能隨(sui)(sui)時(shi)監測電(dian)(dian)池(chi)(chi)工作(zuo)溫度(du)，隨(sui)(sui)時(shi)調(diao)節電(dian)(dian)池(chi)(chi)溫度(du)，來達(da)到最佳的(de)放電(dian)(dian)效果(guo)等功能。

    電(dian)機是(shi)將能源(yuan)轉化為(wei)動(dong)力的(de)工具，相當于燃油車中發動(dong)機的(de)位置(zhi)，決(jue)定新能源(yuan)電(dian)動(dong)車整(zheng)車性(xing)能，包括加速時(shi)間、最高車速等，所(suo)以(yi)要(yao)關注電(dian)機最大轉速和最大輸出(chu)扭(niu)矩等參數(shu)。
