新能源汽車功率大還是小好

和傳統汽車(che)類似，功率(lv)(lv)決定了最(zui)大車(che)速是多(duo)少。和傳統汽車(che)又有所(suo)不同(tong)的(de)(de)是，因為電(dian)(dian)(dian)(dian)動汽車(che)電(dian)(dian)(dian)(dian)能轉(zhuan)化成機械能的(de)(de)效率(lv)(lv)更高，不用(yong)考慮太多(duo)功率(lv)(lv)損耗。電(dian)(dian)(dian)(dian)動汽車(che)的(de)(de)功率(lv)(lv)越(yue)(yue)大，基本其小馬達跑(pao)的(de)(de)越(yue)(yue)快，最(zui)高車(che)速也會更好。電(dian)(dian)(dian)(dian)流越(yue)(yue)小，電(dian)(dian)(dian)(dian)池(chi)的(de)(de)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流越(yue)(yue)小，放電(dian)(dian)(dian)(dian)時間越(yue)(yue)長，因此(ci)兩(liang)個同(tong)功率(lv)(lv)的(de)(de)電(dian)(dian)(dian)(dian)機，電(dian)(dian)(dian)(dian)壓(ya)高的(de)(de)比電(dian)(dian)(dian)(dian)壓(ya)低(di)的(de)(de)跑(pao)的(de)(de)里(li)程能多(duo)些(xie)（電(dian)(dian)(dian)(dian)池(chi)相(xiang)同(tong)的(de)(de)情況(kuang)下）。

新能源汽車綜合最大功率是什么意思

綜合最大功率是(shi)汽車(che)發動機(ji)重要(yao)的(de)數據(ju)，也是(shi)衡量一款車(che)性能指(zhi)標的(de)主要(yao)依據(ju)，其中(zhong)，最大功率決定的(de)是(shi)汽車(che)的(de)最高時速(su)及中(zhong)后段加速(su)能力。

新能源汽車的額定功率是什么意思

額定轉速對應輸出額定功率，電機的工作特(te)性曲線上，空(kong)(kong)載(zai)和(he)過載(zai)都是禁止的，對異步(bu)電(dian)機(ji)(ji)而言，空(kong)(kong)載(zai)容易造成空(kong)(kong)載(zai)電(dian)流(liu)過大，燒毀繞組；過載(zai)則使電(dian)機(ji)(ji)工作于特(te)性邊緣，減少壽命。

一般電動車電機的(de)額(e)定功率點(dian)可以是150W，180W或(huo)200W以上，額(e)定點(dian)越高表示(shi)電機的(de)熱性能越好，成本也越高。

新能源汽車在什么時候會出現峰值功率

新(xin)能源汽(qi)車在(zai)上坡起步、爬坡和加速過程工況下會出現峰值功(gong)率。

電(dian)(dian)動(dong)汽(qi)車(che)(che)(che)的(de)(de)心臟是它的(de)(de)驅(qu)動(dong)電(dian)(dian)機，其性(xing)能必須(xu)符合汽(qi)車(che)(che)(che)的(de)(de)動(dong)力性(xing)需求。電(dian)(dian)動(dong)汽(qi)車(che)(che)(che)的(de)(de)動(dong)力性(xing)主要(yao)由以下三個指標(biao)(biao)來(lai)評定：汽(qi)車(che)(che)(che)的(de)(de)最高車(che)(che)(che)速(su)、汽(qi)車(che)(che)(che)的(de)(de)加(jia)速(su)時間(jian)、汽(qi)車(che)(che)(che)能爬上的(de)(de)最大坡度。為滿足電(dian)(dian)動(dong)汽(qi)車(che)(che)(che)的(de)(de)動(dong)力性(xing)指標(biao)(biao)，驅(qu)動(dong)電(dian)(dian)機的(de)(de)理想驅(qu)動(dong)特性(xing)應(ying)具有低速(su)恒轉矩和(he)高速(su)恒功率(lv)的(de)(de)特性(xing)。

電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)巡航行駛時(shi)(shi)，是(shi)以驅動(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)連續運(yun)行時(shi)(shi)的(de)工作特性(xing)來(lai)滿足汽(qi)(qi)車(che)的(de)動(dong)力性(xing)要求。由于電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)在其過(guo)載(zai)(zai)能(neng)(neng)(neng)(neng)力范圍內能(neng)(neng)(neng)(neng)夠自(zi)動(dong)適應負載(zai)(zai)的(de)變化，所(suo)以電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)總是(shi)利(li)用(yong)其過(guo)載(zai)(zai)能(neng)(neng)(neng)(neng)力即峰(feng)值(zhi)(zhi)參數來(lai)滿足電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)在上坡起步、爬坡和加(jia)速過(guo)程工況下(xia)動(dong)力性(xing)的(de)要求。為了減小(xiao)驅動(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)電(dian)(dian)(dian)(dian)流(liu)，通常希望驅動(dong)電(dian)(dian)(dian)(dian)機(ji)(ji)能(neng)(neng)(neng)(neng)用(yong)最小(xiao)的(de)峰(feng)值(zhi)(zhi)功率(lv)來(lai)滿足電(dian)(dian)(dian)(dian)動(dong)汽(qi)(qi)車(che)的(de)設計要求。
