  汽車電(dian)(dian)瓶(ping)屬于啟動(dong)性蓄電(dian)(dian)池。通過鉛與硫(liu)酸的化學反(fan)應,達(da)到儲(放(fang))電(dian)(dian)能(neng)的物(wu)理作用。面板(ban)標(biao)注為(wei)(wei)(wei)xQWxxA/HxxxA,舉例(li):6QW55A/H300A,既為(wei)(wei)(wei):6節(jie)鉛酸電(dian)(dian)池,電(dian)(dian)量55安(an)(an)/時(shi)(shi),最大(da)放(fang)電(dian)(dian)電(dian)(dian)流(liu)300安(an)(an)培。主(zhu)要(yao)指(zhi)標(biao):電(dian)(dian)壓(ya):單(dan)位伏(fu)(fu)特(te)(V)鉛酸電(dian)(dian)池每單(dan)節(jie)(格(ge))2,0伏(fu)(fu)特(te)。充電(dian)(dian)終(zhong)止電(dian)(dian)壓(ya)2.17—2.2伏(fu)(fu)特(te),放(fang)電(dian)(dian)終(zhong)止電(dian)(dian)壓(ya)1.75伏(fu)(fu)特(te)。電(dian)(dian)量單(dan)位為(wei)(wei)(wei)安(an)(an)/小時(shi)(shi)(A/H),常(chang)用多(duo)為(wei)(wei)(wei)40—70安(an)(an)/小時(shi)(shi)。以(yi)(yi)50安(an)(an)/時(shi)(shi)為(wei)(wei)(wei)例(li):以(yi)(yi)5安(an)(an)培電(dian)(dian)流(liu)持續(xu)(xu)放(fang)電(dian)(dian),可連(lian)續(xu)(xu)放(fang)電(dian)(dian)10小時(shi)(shi)(也稱十(shi)小時(shi)(shi)放(fang)電(dian)(dian)率)。
  最大(da)(da)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu):安培。直(zhi)流(liu)電(dian)(dian)(dian)機(ji)啟(qi)動瞬(shun)間電(dian)(dian)(dian)壓(ya)降(jiang)(jiang)為(wei)(wei)0,電(dian)(dian)(dian)流(liu)無限大(da)(da)。常(chang)見300—400安培之間。冷車阻力(li)(li)大(da)(da),放(fang)電(dian)(dian)(dian)(起動)電(dian)(dian)(dian)流(liu)大(da)(da)且時間長,熱(re)車阻力(li)(li)小,狀態相反。充(chong)(chong)放(fang)電(dian)(dian)(dian)循環次(ci)(ci)(ci)數,國(guo)際暢(chang)行標準多在(zai)8000—20000次(ci)(ci)(ci)之間。隨(sui)著充(chong)(chong)放(fang)電(dian)(dian)(dian)次(ci)(ci)(ci)數增加,化學活性降(jiang)(jiang)低,各(ge)項(xiang)指標降(jiang)(jiang)低,就(jiu)(jiu)離終止壽命(ming)不遠了(le)(le)。電(dian)(dian)(dian)解(jie)液比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong):以室溫(wen)(wen)25度,滿(man)電(dian)(dian)(dian)為(wei)(wei)1.28,電(dian)(dian)(dian)壓(ya)0時,比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)1.0。溫(wen)(wen)度升(sheng)高,比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)上(shang)(shang)升(sheng),溫(wen)(wen)度降(jiang)(jiang)低比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)降(jiang)(jiang)低。常(chang)見北方寒冷地區啟(qi)動困難,與(yu)溫(wen)(wen)度有直(zhi)接關系。老司(si)機(ji)將開水(shui)澆電(dian)(dian)(dian)池(chi)(chi),就(jiu)(jiu)是這(zhe)個道理(li)。長時間不用,電(dian)(dian)(dian)解(jie)液上(shang)(shang)下比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)不同(tong)產生(sheng)電(dian)(dian)(dian)位差(cha),即(ji)造(zao)成自放(fang)電(dian)(dian)(dian)。這(zhe)就(jiu)(jiu)是為(wei)(wei)什(shen)么(me)放(fang)時間長了(le)(le),電(dian)(dian)(dian)池(chi)(chi)沒電(dian)(dian)(dian)的原因。免維護(hu)電(dian)(dian)(dian)池(chi)(chi)面板上(shang)(shang)的圓(yuan)形綠(lv)色(se)標志,就(jiu)(jiu)是比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)計(ji)(ji)觀察(cha)窗(chuang),比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)高時比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)計(ji)(ji)上(shang)(shang)浮接近(jin)觀察(cha)窗(chuang),綠(lv)色(se)標示即(ji)明顯。當(dang)比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)底時,比(bi)(bi)(bi)(bi)(bi)(bi)重(zhong)(zhong)(zhong)計(ji)(ji)遠離觀察(cha)窗(chuang),綠(lv)色(se)標示逐漸變小至消失(shi),提示您:電(dian)(dian)(dian)量低,該(gai)充(chong)(chong)電(dian)(dian)(dian)了(le)(le)。
  充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓:單位(wei)伏(fu)(fu)特(te)。標準充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)終止電(dian)(dian)(dian)(dian)(dian)(dian)壓17—18伏(fu)(fu)特(te),汽(qi)(qi)車(che)發動(dong)機充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓13—14伏(fu)(fu)特(te)。為什么汽(qi)(qi)車(che)的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓比(bi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機的底(di)呢(ni)?汽(qi)(qi)車(che)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)機經(jing)整流調壓后,為車(che)用電(dian)(dian)(dian)(dian)(dian)(dian)器使用,為保(bao)護電(dian)(dian)(dian)(dian)(dian)(dian)子器件(jian),電(dian)(dian)(dian)(dian)(dian)(dian)壓不能(neng)過高。這就(jiu)造成電(dian)(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)不能(neng)充(chong)滿,但能(neng)夠(gou)滿足(zu)啟(qi)動(dong)需(xu)求(qiu),電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)常在(zai)滿電(dian)(dian)(dian)(dian)(dian)(dian)容量(liang)的百分(fen)之(zhi)七(qi)十(shi)上下。我們的手機電(dian)(dian)(dian)(dian)(dian)(dian)池與(yu)汽(qi)(qi)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)池有(you)(you)很多相似,電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)低于(yu)百分(fen)之(zhi)二十(shi)就(jiu)會關機,汽(qi)(qi)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)池也是如此。苦于(yu)沒有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)壓(實電(dian)(dian)(dian)(dian)(dian)(dian)壓)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)顯示,能(neng)否啟(qi)動(dong)就(jiu)在(zai)一兩次期待之(zhi)間(誤(wu)區:能(neng)啟(qi)動(dong)就(jiu)有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian),就(jiu)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)足(zu)),剛剛還能(neng)著車(che),現在(zai)就(jiu)沒電(dian)(dian)(dian)(dian)(dian)(dian)了,就(jiu)是這個原因。
  免維護(hu)不等于不維護(hu),經常觀察比重觀察窗,可(ke)以(yi)防(fang)止(zhi)虧電(dian)(dian)。個人建議(yi):每年入冬前進(jin)行一次充(chong)電(dian)(dian)機養護(hu)性充(chong)電(dian)(dian),可(ke)避免虧電(dian)(dian),并延長蓄電(dian)(dian)池壽命。當然,養護(hu)充(chong)電(dian)(dian)時能(neng)夠進(jin)行放電(dian)(dian)(測試電(dian)(dian)量)檢(jian)查更好!
