一、電動車電機功率1200w好還是800w好
電動車電機功(gong)率越(yue)高(gao),電(dian)(dian)(dian)(dian)(dian)動車也會跑(pao)得(de)越(yue)快(kuai),當然(ran)這個是(shi)在電(dian)(dian)(dian)(dian)(dian)池(chi)供應電(dian)(dian)(dian)(dian)(dian)能(neng)要(yao)能(neng)滿(man)足的(de)(de)前提(ti)下來(lai)實現的(de)(de),800W的(de)(de)電(dian)(dian)(dian)(dian)(dian)機,車子大(da)概能(neng)跑(pao)40公(gong)里(li)/小時的(de)(de)速度;1200W約48公(gong)里(li)/小時。但是(shi)電(dian)(dian)(dian)(dian)(dian)機功(gong)率越(yue)大(da),耗電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)也越(yue)大(da),在相同電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)的(de)(de)情況(kuang)下,800w的(de)(de)電(dian)(dian)(dian)(dian)(dian)機續航就會優(you)于1200w。
二、電動車電機功率越大越好嗎
電(dian)(dian)動車(che)功率(lv)(lv)越大,并不意味(wei)著電(dian)(dian)動車(che)性能就越好,如(ru)果電(dian)(dian)動車(che)生產制造(zao)只是要求(qiu)功率(lv)(lv)大,廠家直接裝大號電(dian)(dian)機就可以了(le),實際上當(dang)然不是這么簡單的事情了(le)。
目前電動自行車的新國標,在很多地方已經開始落地執行了,新國標要求電機的(de)功(gong)(gong)率(lv)(lv)不能(neng)(neng)超過400W,只要大(da)于這(zhe)個功(gong)(gong)率(lv)(lv)是不能(neng)(neng)合法上路的(de),所以電(dian)動(dong)車(che)(che)功(gong)(gong)率(lv)(lv)大(da)了,比如是600W和(he)(he)800W的(de),能(neng)(neng)否(fou)使用都是個大(da)問題。電(dian)動(dong)車(che)(che)功(gong)(gong)率(lv)(lv)大(da)了,意味著動(dong)力和(he)(he)極速會(hui)增加(jia),但(dan)是電(dian)池,控制(zhi)器和(he)(he)車(che)(che)架,輪胎(tai)還(huan)有(you)剎(cha)車(che)(che)都要配(pei)合到位,否(fou)則會(hui)拖累續(xu)航里程和(he)(he)安全性能(neng)(neng),這(zhe)樣下來成本會(hui)飆升,很(hen)多人買不起,而且未(wei)必會(hui)帶(dai)來良好的(de)用戶體(ti)驗。
電動車選(xuan)(xuan)擇(ze)電(dian)(dian)機(ji)功(gong)(gong)(gong)率的同時(shi),也(ye)要看電(dian)(dian)池(chi)容量(liang)是(shi)多少(shao),電(dian)(dian)池(chi)容量(liang)多少(shao)決定著續航里程,而影(ying)響電(dian)(dian)動(dong)車(che)速(su)度的主要是(shi)電(dian)(dian)機(ji)控(kong)制器,如果電(dian)(dian)動(dong)車(che)體積小配(pei)大功(gong)(gong)(gong)率電(dian)(dian)機(ji),控(kong)制器需要提高輸出電(dian)(dian)流,這(zhe)樣反而會更(geng)耗電(dian)(dian),所(suo)以(yi)(yi)如果是(shi)代(dai)步電(dian)(dian)動(dong)車(che),可(ke)以(yi)(yi)選(xuan)(xuan)擇(ze)小功(gong)(gong)(gong)率的,如果是(shi)載(zai)重貨(huo)的,可(ke)以(yi)(yi)選(xuan)(xuan)擇(ze)大功(gong)(gong)(gong)率的。
