一、電動車電機功率1200w好還是800w好
電動車電機功率越高,電(dian)動車(che)也會(hui)跑得越快,當然這個是(shi)(shi)在(zai)電(dian)池供(gong)應電(dian)能要能滿足的(de)(de)前(qian)提下來實現的(de)(de),800W的(de)(de)電(dian)機,車(che)子大(da)概能跑40公里(li)/小時的(de)(de)速度;1200W約48公里(li)/小時。但(dan)是(shi)(shi)電(dian)機功率越大(da),耗(hao)電(dian)量也越大(da),在(zai)相同電(dian)量的(de)(de)情況下,800w的(de)(de)電(dian)機續(xu)航(hang)就會(hui)優于1200w。
二、電動車電機功率越大越好嗎
電(dian)(dian)(dian)動車(che)功(gong)(gong)率越大(da),并不(bu)意味著電(dian)(dian)(dian)動車(che)性能(neng)就越好,如果電(dian)(dian)(dian)動車(che)生產制(zhi)造只(zhi)是要求功(gong)(gong)率大(da),廠家直(zhi)接裝大(da)號電(dian)(dian)(dian)機就可以了,實際(ji)上當然(ran)不(bu)是這么(me)簡單的(de)事情(qing)了。
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)(de)功率不能超過400W,只要大(da)于這個(ge)(ge)功率是(shi)(shi)不能合法上(shang)路的(de)(de),所以電(dian)動車功率大(da)了,比(bi)如是(shi)(shi)600W和800W的(de)(de),能否使用(yong)都是(shi)(shi)個(ge)(ge)大(da)問題(ti)。電(dian)動車功率大(da)了,意味著動力(li)和極速(su)會增加(jia),但是(shi)(shi)電(dian)池,控(kong)制器和車架,輪胎還有剎車都要配合到位,否則會拖累續航里程和安全(quan)性能,這樣下來成本會飆升,很多人(ren)買(mai)不起,而且(qie)未(wei)必會帶來良好的(de)(de)用(yong)戶體驗。
電動車選擇(ze)電(dian)(dian)(dian)機(ji)(ji)功(gong)(gong)(gong)(gong)率(lv)的(de)(de)(de)同(tong)時,也要看電(dian)(dian)(dian)池容量是多少,電(dian)(dian)(dian)池容量多少決(jue)定著續(xu)航里程,而影響電(dian)(dian)(dian)動(dong)(dong)車速(su)度(du)的(de)(de)(de)主要是電(dian)(dian)(dian)機(ji)(ji)控制器,如(ru)果電(dian)(dian)(dian)動(dong)(dong)車體積小(xiao)配大(da)功(gong)(gong)(gong)(gong)率(lv)電(dian)(dian)(dian)機(ji)(ji),控制器需要提高(gao)輸出(chu)電(dian)(dian)(dian)流(liu),這樣反而會更耗電(dian)(dian)(dian),所以(yi)如(ru)果是代步電(dian)(dian)(dian)動(dong)(dong)車,可(ke)以(yi)選擇(ze)小(xiao)功(gong)(gong)(gong)(gong)率(lv)的(de)(de)(de),如(ru)果是載(zai)重(zhong)貨的(de)(de)(de),可(ke)以(yi)選擇(ze)大(da)功(gong)(gong)(gong)(gong)率(lv)的(de)(de)(de)。
