  汽車電(dian)(dian)(dian)瓶屬(shu)于啟(qi)動(dong)性蓄電(dian)(dian)(dian)池。通過鉛與(yu)硫(liu)酸的化學(xue)反應,達到儲(放(fang))電(dian)(dian)(dian)能的物(wu)理作用。面板標注為xQWxxA/HxxxA,舉例:6QW55A/H300A,既為:6節鉛酸電(dian)(dian)(dian)池,電(dian)(dian)(dian)量(liang)55安(an)/時(shi),最大放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流300安(an)培(pei)(pei)。主要指標:電(dian)(dian)(dian)壓:單(dan)位伏特(te)(V)鉛酸電(dian)(dian)(dian)池每單(dan)節(格)2,0伏特(te)。充電(dian)(dian)(dian)終止電(dian)(dian)(dian)壓2.17—2.2伏特(te),放(fang)電(dian)(dian)(dian)終止電(dian)(dian)(dian)壓1.75伏特(te)。電(dian)(dian)(dian)量(liang)單(dan)位為安(an)/小時(shi)(A/H),常用多為40—70安(an)/小時(shi)。以50安(an)/時(shi)為例:以5安(an)培(pei)(pei)電(dian)(dian)(dian)流持續(xu)(xu)放(fang)電(dian)(dian)(dian),可連續(xu)(xu)放(fang)電(dian)(dian)(dian)10小時(shi)(也稱十(shi)小時(shi)放(fang)電(dian)(dian)(dian)率(lv))。
  最大(da)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu):安培(pei)。直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)機啟動(dong)瞬間電(dian)(dian)(dian)(dian)(dian)(dian)壓降(jiang)為0,電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)無限大(da)。常見(jian)300—400安培(pei)之間。冷車(che)阻(zu)力(li)大(da),放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(起動(dong))電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)大(da)且時間長(chang),熱車(che)阻(zu)力(li)小,狀(zhuang)態相反(fan)。充放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)循環(huan)次(ci)數,國(guo)際(ji)暢行標(biao)準(zhun)多在8000—20000次(ci)之間。隨著充放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)次(ci)數增加,化(hua)學活性降(jiang)低(di),各項指標(biao)降(jiang)低(di),就(jiu)離終止壽命不(bu)(bu)遠了(le)(le)。電(dian)(dian)(dian)(dian)(dian)(dian)解液比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong):以室溫(wen)25度(du),滿(man)電(dian)(dian)(dian)(dian)(dian)(dian)為1.28,電(dian)(dian)(dian)(dian)(dian)(dian)壓0時,比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)1.0。溫(wen)度(du)升高,比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)上(shang)升,溫(wen)度(du)降(jiang)低(di)比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)降(jiang)低(di)。常見(jian)北方(fang)寒(han)冷地區啟動(dong)困難,與溫(wen)度(du)有直接關(guan)系。老司機將開水澆電(dian)(dian)(dian)(dian)(dian)(dian)池,就(jiu)是這(zhe)個道(dao)理。長(chang)時間不(bu)(bu)用,電(dian)(dian)(dian)(dian)(dian)(dian)解液上(shang)下比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)不(bu)(bu)同(tong)產生電(dian)(dian)(dian)(dian)(dian)(dian)位差,即造成(cheng)自(zi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)。這(zhe)就(jiu)是為什么(me)放(fang)時間長(chang)了(le)(le),電(dian)(dian)(dian)(dian)(dian)(dian)池沒電(dian)(dian)(dian)(dian)(dian)(dian)的原因。免維(wei)護電(dian)(dian)(dian)(dian)(dian)(dian)池面(mian)板(ban)上(shang)的圓形(xing)綠色標(biao)志,就(jiu)是比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)計觀察(cha)窗(chuang),比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)高時比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)計上(shang)浮(fu)接近觀察(cha)窗(chuang),綠色標(biao)示(shi)即明顯。當比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)底時,比(bi)(bi)重(zhong)(zhong)(zhong)(zhong)(zhong)計遠離觀察(cha)窗(chuang),綠色標(biao)示(shi)逐(zhu)漸變(bian)小至消失,提示(shi)您:電(dian)(dian)(dian)(dian)(dian)(dian)量低(di),該充電(dian)(dian)(dian)(dian)(dian)(dian)了(le)(le)。
  充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya):單位伏(fu)特(te)。標準充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)終止電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)17—18伏(fu)特(te),汽(qi)車(che)發動機(ji)(ji)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)13—14伏(fu)特(te)。為(wei)什么汽(qi)車(che)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)比充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)底呢?汽(qi)車(che)放電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)經(jing)整流調(diao)壓(ya)(ya)(ya)(ya)后,為(wei)車(che)用(yong)電(dian)(dian)(dian)(dian)(dian)器(qi)使用(yong),為(wei)保護電(dian)(dian)(dian)(dian)(dian)子(zi)器(qi)件,電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)不能(neng)過(guo)高(gao)。這就(jiu)造(zao)成電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)量不能(neng)充(chong)(chong)(chong)滿(man),但能(neng)夠滿(man)足啟(qi)動需求,電(dian)(dian)(dian)(dian)(dian)量常(chang)在(zai)滿(man)電(dian)(dian)(dian)(dian)(dian)容(rong)量的(de)百分之(zhi)七十(shi)上下。我們的(de)手機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)池與汽(qi)車(che)電(dian)(dian)(dian)(dian)(dian)池有很(hen)多相似,電(dian)(dian)(dian)(dian)(dian)量低于(yu)百分之(zhi)二(er)十(shi)就(jiu)會關機(ji)(ji),汽(qi)車(che)電(dian)(dian)(dian)(dian)(dian)池也是如此。苦于(yu)沒有電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(實電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya))電(dian)(dian)(dian)(dian)(dian)量顯(xian)示,能(neng)否啟(qi)動就(jiu)在(zai)一兩次期待之(zhi)間(誤區:能(neng)啟(qi)動就(jiu)有電(dian)(dian)(dian)(dian)(dian),就(jiu)電(dian)(dian)(dian)(dian)(dian)量足),剛剛還能(neng)著車(che),現(xian)在(zai)就(jiu)沒電(dian)(dian)(dian)(dian)(dian)了,就(jiu)是這個原因。
  免(mian)維護(hu)不等于(yu)不維護(hu),經常(chang)觀察比重觀察窗,可以(yi)防(fang)止虧(kui)電(dian)(dian)(dian)(dian)。個人建議(yi):每年入冬前進行一次充(chong)電(dian)(dian)(dian)(dian)機養護(hu)性充(chong)電(dian)(dian)(dian)(dian),可避(bi)免(mian)虧(kui)電(dian)(dian)(dian)(dian),并延長蓄電(dian)(dian)(dian)(dian)池壽(shou)命。當然,養護(hu)充(chong)電(dian)(dian)(dian)(dian)時(shi)能夠(gou)進行放(fang)電(dian)(dian)(dian)(dian)(測試電(dian)(dian)(dian)(dian)量)檢查更好(hao)!
