Raws li peb txhua tus paub, thaum peb xaiv lub teeb ci hnub ci, peb yuav tsum tau ua qee yam kev npaj.Piv txwv li, peb yuav tsum paub qhov twg rau nruab lub teeb?Txoj kev, ib txoj kab, ob txoj kab yog dab tsi?Muaj pes tsawg hnub los nag?Thiab dab tsi yog qhov teeb pom kev zoo thaum hmo ntuj.
Tom qab paub tag nrho cov ntaub ntawv no, peb tuaj yeem paub tias lub hnub ci vaj huam sib luag thiab roj teeb loj npaum li cas peb yuav siv, thiab tom qab ntawd peb tuaj yeem tswj tau tus nqi.
Cia peb ua piv txwv, rau 12v, 60W txoj kev teeb pom kev zoo, yog tias nws yuav ua haujlwm rau 7 teev txhua hmo, thiab muaj 3 hnub los nag tas li, thiab hnub ci piv yog 4 teev.Kev suav yog raws li nram no.
1.Peev xwm ntawm lub roj teeb
a. Xam qhov tam sim no
Tam sim no = 60W ÷ 12V＝5A
b.Xam lub peev xwm ntawm lub roj teeb
Roj teeb = Tam sim no * lub sijhawm ua haujlwm txhua hnub * hnub los nag tas li = 105AH.
Peb yuav tsum tau ua tib zoo saib, 105AH tsis yog lub peev xwm kawg, peb tseem yuav tsum xav txog qhov teeb meem tshaj tawm thiab tshaj tawm.Hauv kev siv txhua hnub, 140AH tsuas yog 70% rau 85% piv rau tus qauv.
Lub roj teeb yuav tsum yog 105÷0.85 = 123AH.
2.Hnub ci vaj huam sib luag Wattage
Ua ntej xam lub hnub ci vaj huam sib luag wattage, peb yuav tsum paub tias lub hnub ci vaj huam sib luag yog ua los ntawm silicon chips.Tsis tu ncua ib lub hnub ci vaj huam sib luag yuav muaj 36pcs silicon chips nyob rau hauv parallel los yog series.Qhov voltage ntawm txhua lub silicon nti yog li 0.48 txog 0.5V, thiab qhov voltage ntawm tag nrho lub hnub ci vaj huam sib luag yog li 17.3-18V.Tsis tas li ntawd, thaum lub sij hawm xam, peb yuav tsum tau tawm 20% qhov chaw rau lub hnub ci vaj huam sib luag.
Hnub ci vaj huam sib luag wattage ÷ ua haujlwm voltage = (tam sim no × lub sijhawm ua haujlwm txhua hmo × 120%).
Hnub ci vaj huam sib luag Wattage Min =(5 x 7 h x 120％)4h x 17.3V＝182 wb
Hnub ci vaj huam sib luag Wattage Max =(5 x 7 h x 120％)4h x 18v＝189 wb
Txawm li cas los xij, qhov no tsis yog qhov kawg wattage ntawm lub hnub ci vaj huam sib luag.Thaum lub sij hawm ua hauj lwm ntawm lub hnub ci teeb, peb kuj yuav tsum tau xav txog cov hlau poob thiab cov maub los poob.Thiab lub hnub ci vaj huam sib luag tiag tiag yuav tsum yog 5% ntau dua piv rau cov ntaub ntawv suav 182W lossis 189W.
Hnub ci vaj huam sib luag Wattage Min＝182 x 105 hli＝191 wb
Hnub ci vaj huam sib luag Wattage Max＝189 x 125 hli＝236 wb
Tag nrho cov, nyob rau hauv peb cov ntaub ntawv, lub roj teeb yuav tsum muaj ntau tshaj 123AH, thiab lub hnub ci vaj huam sib luag yuav tsum nyob rau ntawm 191-236W.
Thaum peb xaiv lub hnub ci txoj kev teeb pom kev zoo, raws li cov qauv kev suav no, peb tuaj yeem txheeb xyuas lub peev xwm ntawm lub hnub ci vaj huam sib luag thiab cov roj teeb ntawm peb tus kheej, Qhov no tuaj yeem pab peb txuag tus nqi rau qee qhov, uas yuav ua rau peb muaj kev paub zoo sab nraum zoov.
