  很(hen)多(duo)人(ren)都有一個誤(wu)區,以為(wei)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)(shi)汽車(che)(che)上的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan),其實這是(shi)(shi)不對的,發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)才是(shi)(shi)汽車(che)(che)上真正(zheng)的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。當(dang)汽車(che)(che)啟動(dong)后,在發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)正(zheng)常(chang)的情況下,它的輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓會高于蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的電(dian)(dian)(dian)(dian)(dian)(dian)壓,發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)向(xiang)所有用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)(起動(dong)機(ji)(ji)除(chu)外)供電(dian)(dian)(dian)(dian)(dian)(dian),同(tong)時(shi)(shi)向(xiang)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian);而(er)此時(shi)(shi)的蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)(shi)作為(wei)一個負載存在的,它不再向(xiang)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)供電(dian)(dian)(dian)(dian)(dian)(dian),而(er)是(shi)(shi)需要發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)給它充電(dian)(dian)(dian)(dian)(dian)(dian),也在消耗(hao)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)能。只有當(dang)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)過(guo)多(duo)、用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)量超過(guo)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的供電(dian)(dian)(dian)(dian)(dian)(dian)能力時(shi)(shi),蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)會協助發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)向(xiang)各種用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)供電(dian)(dian)(dian)(dian)(dian)(dian),此時(shi)(shi)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是(shi)(shi)放電(dian)(dian)(dian)(dian)(dian)(dian)的,屬于一種輔助電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。
  如(ru)果車(che)上有大(da)功率(lv)的(de)(de)電(dian)(dian)(dian)氣(qi)設(she)(she)備,它(ta)的(de)(de)用電(dian)(dian)(dian)量超過了(le)(le)(le)發(fa)電(dian)(dian)(dian)機(ji)的(de)(de)供電(dian)(dian)(dian)能(neng)力,此時的(de)(de)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)就會參與工作,也給(gei)這個設(she)(she)備供電(dian)(dian)(dian)。注意(yi):在此時發(fa)電(dian)(dian)(dian)機(ji)已(yi)經(jing)無(wu)力再給(gei)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)電(dian)(dian)(dian),全部(bu)的(de)(de)電(dian)(dian)(dian)能(neng)除了(le)(le)(le)維持汽車(che)的(de)(de)正常(chang)運行(xing)外,其余(yu)的(de)(de)全都給(gei)了(le)(le)(le)這個大(da)功率(lv)的(de)(de)電(dian)(dian)(dian)氣(qi)設(she)(she)備,并且還不夠用,需要蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)來協助。在這種情況(kuang)下,蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)只放電(dian)(dian)(dian)不充(chong)電(dian)(dian)(dian),時間長(chang)了(le)(le)(le)一(yi)定(ding)會損(sun)壞;如(ru)果蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)深度(du)放電(dian)(dian)(dian),以(yi)后是(shi)無(wu)法(fa)恢復的(de)(de)。所以(yi),在汽車(che)上安(an)裝電(dian)(dian)(dian)氣(qi)設(she)(she)備時,要充(chong)分考慮發(fa)電(dian)(dian)(dian)機(ji)和(he)蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)承受(shou)能(neng)力。
  還有一點也要注意,那就是大功率的電氣設備也會影響汽車的正常運行,并增加汽車的油耗。一些老司機應該記得,以前有一些三缸發動機,比如夏利,奧托等,這些車在怠速下打開前大燈,發動機馬上就會劇烈抖動,只有提高發動機的轉速,抖動才會減小,但是汽車仍然會加速無力。這就是因為大燈消耗了一部分的電能,使點火系統得到的電能減少了,點火能量降低,發動機燃燒變差了,我們俗稱為“奪電”。這就是典型的大功率電氣設備影響發動機運行案例。現在的汽車上如果安裝了這樣的電氣設備,相信也會有這樣的后果。上海施能(neng)電器設備有限公(gong)司(si)始建于1984年,上海市高新技術企業,中國工業車輛優秀配套供應商,上海電器行業名優產品,主要生產工頻系列充電機,高頻系列充電機,鋰電池充電機,系列放電機,系列充放電機等電器產品。
