Qhov twg yog qhov zoo dua rau High-tam sim no them ceev lossis high-voltage ceev them?
Nrog rau kev txhim kho ntawm lub xov tooj ntawm tes them thev naus laus zis, feem ntau ntawm cov xov tooj smartphones tam sim no txais cov kev daws teeb meem ceev ceev. Peb tau paub txog OPPO VOOC flash charging, Qualcomm QC ceev them, Huawei SuperCharge them, thiab lwm yam.
Yog li qhov twg yog qhov zoo dua, high-voltage fast charging lossis high-tam sim no them ceev?
Raws li lub zog P=tam sim no (I) x voltage (U), nce lub zog them ntawm lub xov tooj ntawm tes tsis muaj dab tsi ntau tshaj li qhov ua kom them tam sim no lossis nce qhov them nqi hluav taws xob, lossis ob qho tib si.
Tam sim no, kev them nyiaj ceev suav nrog kev them nqi hluav taws xob ceev ceev thiab kev them nyiaj tam sim no. Tus neeg sawv cev ntawm high voltage ceev them yog Qualcomm QuickCharge ceev them thev naus laus zis. Qualcomm thaum kawg tau muab QC 4+ them lub taub hau ceev ntawm lub Snapdragon Technology Summit thib ob tsis ntev dhau los. Nws tuaj yeem pom los ntawm qhov tsis sib xws uas Qualcomm QC 4+ txhawb nqa nrawm txog 27W. Cov zis hluav taws xob yog 5V / 3A, 9V / 3A, 11V / 2.4A, 12V / 2.25A. Los ntawm cov kev tsis sib xws, Qualcomm QC 4+ tseem yog high-voltage thiab ceev. Rau txoj kev them nqi, qhov siab tshaj plaws tam sim no tsis tshaj 3A.
Qualcomm's QC 4+ yog ib qho ntawm ob peb qhov kev daws teeb meem ceev ceev uas tseem hais txog kev them nyiaj ceev ceev. Qhov twg zoo dua? Qhov qis-voltage thiab high-tam sim no them ceev daws teeb meem zoo dua. Qhov pom tseeb tshaj plaws txhua hnub yog kev them nyiaj ceev. Tib lub sijhawm, kev them nyiaj kub kuj tseem qis.
Qhov hluav taws xob tsawg-voltage thiab high-tam sim no them ceev yog feem ntau nyob ib ncig ntawm 5V, thiab qhov hluav taws xob ntawm lub xov tooj ntawm tes roj teeb phim cov ntaub ntawv no. Yog li ntawd, lub zog hloov dua siab tshiab efficiency yog siab dua thaum them lub xov tooj ntawm tes nrog tsawg-voltage thiab high-tam sim no.
Vim hais tias feem ntau ntawm lub zog poob nyob rau hauv cov txheej txheem them nyiaj yog nyob rau hauv lub tshav kub tiam, qhov qis dua lub tshav kub tiam, lub siab dua conversion efficiency. Txawm li cas los xij, cov txheej txheem them nqi hluav taws xob ceev ceev tsis muaj qhov zoo dua, thiab cov cua sov tsim tawm thaum lub sij hawm them nyiaj ntau dua.
Ntxiv nrog rau qhov tsawg-voltage thiab high-tam sim no them ceev ceev thiab high-voltage fast charging, kuj tseem muaj cov thev naus laus zis ceev uas siv txoj kev sib haum xeeb. Qhov voltage thiab tam sim no tau nce me ntsis, thiab tib lub zog them tuaj yeem ua tiav.
Qualcomm' s QuickCharge txhawb nqa qhov no. Piv txwv li, qhov tseeb QC 4+ txhawb nqa 12V / 2.25A ceev them thiab kuj muaj 9V / 3A iav, tab sis txawm tias txoj kev cuam tshuam no tsis tas yuav muaj lub zog hloov pauv. Muaj tsawg-voltage fast charging thiab high-speed charging. Raws li yog vim li cas Qualcomm insists ntawm high-voltage ceev them, kuv tsis paub.
Nws tuaj yeem pom los ntawm cov saum toj no tias txawm hais tias cov npe ntawm cov txheej txheem them nyiaj ceev ceev ntawm kev ua lag luam muaj ntau yam, qhov kev them nyiaj ceev ceev tiag tiag tsuas yog high-voltage ceev Qhov zoo ntawm cov hluav taws xob tsawg thaum lub sij hawm ntawm lub fuselage pib kis mus maj mam. .
Nyob rau hauv lub neej yav tom ntej, nrog kev siv thev naus laus zis, kev daws teeb meem ceev ceev nrog cov hluav taws xob siab thiab siab tam sim no yuav tshwm sim.
