很多(duo)人(ren)都有一(yi)個誤區，以為(wei)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是汽車上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，其(qi)實這是不對的(de)，發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)才是汽車上真(zhen)正的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。當(dang)汽車啟動(dong)后，在(zai)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)正常的(de)情況下，它(ta)(ta)的(de)輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)會高于蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)向(xiang)(xiang)(xiang)所有用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)（起動(dong)機(ji)(ji)除外）供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，同時(shi)向(xiang)(xiang)(xiang)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)；而此時(shi)的(de)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是作為(wei)一(yi)個負載存在(zai)的(de)，它(ta)(ta)不再向(xiang)(xiang)(xiang)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而是需要發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)給它(ta)(ta)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，也在(zai)消耗發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)。只有當(dang)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)過多(duo)、用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量超(chao)過發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)力時(shi)，蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)會協助發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)向(xiang)(xiang)(xiang)各種(zhong)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，此時(shi)蓄(xu)(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)，屬(shu)于一(yi)種(zhong)輔助電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。
如果車(che)(che)上有大(da)功率(lv)的(de)(de)電(dian)氣設(she)(she)備，它的(de)(de)用(yong)電(dian)量超過(guo)了發(fa)電(dian)機的(de)(de)供電(dian)能(neng)力，此時(shi)的(de)(de)蓄(xu)(xu)電(dian)池(chi)就(jiu)會(hui)參與工作，也給(gei)(gei)這個設(she)(she)備供電(dian)。注意：在(zai)此時(shi)發(fa)電(dian)機已經無力再給(gei)(gei)蓄(xu)(xu)電(dian)池(chi)充(chong)電(dian)，全部的(de)(de)電(dian)能(neng)除了維持汽(qi)(qi)車(che)(che)的(de)(de)正常運行(xing)外，其余的(de)(de)全都給(gei)(gei)了這個大(da)功率(lv)的(de)(de)電(dian)氣設(she)(she)備，并(bing)且還不(bu)夠用(yong)，需要蓄(xu)(xu)電(dian)池(chi)來協(xie)助。在(zai)這種(zhong)情(qing)況下，蓄(xu)(xu)電(dian)池(chi)只(zhi)放電(dian)不(bu)充(chong)電(dian)，時(shi)間(jian)長(chang)了一定會(hui)損壞；如果蓄(xu)(xu)電(dian)池(chi)深度放電(dian)，以后是無法恢(hui)復的(de)(de)。所以，在(zai)汽(qi)(qi)車(che)(che)上安裝電(dian)氣設(she)(she)備時(shi)，要充(chong)分考慮發(fa)電(dian)機和蓄(xu)(xu)電(dian)池(chi)的(de)(de)承受能(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(hai)施(shi)能(neng)電器(qi)設備有限公司始建于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。
如果車(che)(che)上有大(da)功率(lv)的(de)(de)電(dian)氣設(she)(she)備，它的(de)(de)用(yong)電(dian)量超過(guo)了發(fa)電(dian)機的(de)(de)供電(dian)能(neng)力，此時(shi)的(de)(de)蓄(xu)(xu)電(dian)池(chi)就(jiu)會(hui)參與工作，也給(gei)(gei)這個設(she)(she)備供電(dian)。注意：在(zai)此時(shi)發(fa)電(dian)機已經無力再給(gei)(gei)蓄(xu)(xu)電(dian)池(chi)充(chong)電(dian)，全部的(de)(de)電(dian)能(neng)除了維持汽(qi)(qi)車(che)(che)的(de)(de)正常運行(xing)外，其余的(de)(de)全都給(gei)(gei)了這個大(da)功率(lv)的(de)(de)電(dian)氣設(she)(she)備，并(bing)且還不(bu)夠用(yong)，需要蓄(xu)(xu)電(dian)池(chi)來協(xie)助。在(zai)這種(zhong)情(qing)況下，蓄(xu)(xu)電(dian)池(chi)只(zhi)放電(dian)不(bu)充(chong)電(dian)，時(shi)間(jian)長(chang)了一定會(hui)損壞；如果蓄(xu)(xu)電(dian)池(chi)深度放電(dian)，以后是無法恢(hui)復的(de)(de)。所以，在(zai)汽(qi)(qi)車(che)(che)上安裝電(dian)氣設(she)(she)備時(shi)，要充(chong)分考慮發(fa)電(dian)機和蓄(xu)(xu)電(dian)池(chi)的(de)(de)承受能(neng)力。
