很多人都有(you)一個(ge)誤區，以為(wei)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)汽(qi)(qi)車上的(de)電(dian)(dian)(dian)(dian)源，其實這是(shi)不對(dui)的(de)，發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)才是(shi)汽(qi)(qi)車上真正(zheng)的(de)電(dian)(dian)(dian)(dian)源。當汽(qi)(qi)車啟動(dong)后(hou)，在(zai)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)發(fa)電(dian)(dian)(dian)(dian)正(zheng)常的(de)情(qing)況下(xia)，它(ta)的(de)輸出電(dian)(dian)(dian)(dian)壓(ya)會高于蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)壓(ya)，發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)向(xiang)(xiang)所(suo)有(you)用電(dian)(dian)(dian)(dian)設備(bei)（起動(dong)機(ji)(ji)除外）供(gong)(gong)電(dian)(dian)(dian)(dian)，同(tong)時向(xiang)(xiang)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)；而(er)此時的(de)蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)作為(wei)一個(ge)負載存(cun)在(zai)的(de)，它(ta)不再(zai)向(xiang)(xiang)用電(dian)(dian)(dian)(dian)設備(bei)供(gong)(gong)電(dian)(dian)(dian)(dian)，而(er)是(shi)需(xu)要發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)給它(ta)充(chong)電(dian)(dian)(dian)(dian)，也在(zai)消耗發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)電(dian)(dian)(dian)(dian)能。只(zhi)有(you)當用電(dian)(dian)(dian)(dian)設備(bei)過(guo)多、用電(dian)(dian)(dian)(dian)量超(chao)過(guo)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)供(gong)(gong)電(dian)(dian)(dian)(dian)能力時，蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)會協助(zhu)發(fa)電(dian)(dian)(dian)(dian)機(ji)(ji)向(xiang)(xiang)各(ge)種用電(dian)(dian)(dian)(dian)設備(bei)供(gong)(gong)電(dian)(dian)(dian)(dian)，此時蓄(xu)(xu)電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)放電(dian)(dian)(dian)(dian)的(de)，屬于一種輔(fu)助(zhu)電(dian)(dian)(dian)(dian)源。
如(ru)果(guo)車上有大(da)功率(lv)的(de)(de)電(dian)(dian)(dian)氣(qi)設(she)備(bei)，它的(de)(de)用電(dian)(dian)(dian)量超(chao)過了發電(dian)(dian)(dian)機(ji)的(de)(de)供電(dian)(dian)(dian)能力(li)，此時(shi)的(de)(de)蓄(xu)(xu)電(dian)(dian)(dian)池就(jiu)會參與工作，也給這(zhe)個(ge)設(she)備(bei)供電(dian)(dian)(dian)。注(zhu)意(yi)：在此時(shi)發電(dian)(dian)(dian)機(ji)已(yi)經(jing)無力(li)再給蓄(xu)(xu)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)，全部的(de)(de)電(dian)(dian)(dian)能除了維持汽車的(de)(de)正常(chang)運行外，其余的(de)(de)全都給了這(zhe)個(ge)大(da)功率(lv)的(de)(de)電(dian)(dian)(dian)氣(qi)設(she)備(bei)，并且(qie)還不(bu)夠(gou)用，需要(yao)蓄(xu)(xu)電(dian)(dian)(dian)池來(lai)協助。在這(zhe)種(zhong)情況下(xia)，蓄(xu)(xu)電(dian)(dian)(dian)池只放電(dian)(dian)(dian)不(bu)充(chong)電(dian)(dian)(dian)，時(shi)間長了一(yi)定(ding)會損(sun)壞；如(ru)果(guo)蓄(xu)(xu)電(dian)(dian)(dian)池深度放電(dian)(dian)(dian)，以(yi)后是無法恢復的(de)(de)。所以(yi)，在汽車上安裝電(dian)(dian)(dian)氣(qi)設(she)備(bei)時(shi)，要(yao)充(chong)分考慮發電(dian)(dian)(dian)機(ji)和蓄(xu)(xu)電(dian)(dian)(dian)池的(de)(de)承受(shou)能力(li)。
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)施能電器設(she)備有限公(gong)司始建(jian)于(yu)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。
