Qhov twg yog qhov zoo dua, high-voltage fast charging lossis high-tam sim no them ceev?
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 siv cov kev daws teeb meem ceev ceev. Peb paub txog OPPO VOOC flash charging, Qualcomm QC ceev them, Huawei SuperCharge ceev them, thiab lwm yam.
Raws li lub hwj chim 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 kev nce nqi tam sim no lossis qhov them nqi hluav taws xob lossis ob qho tib si.
Tam sim no, kev them nyiaj ceev suav nrog kev them nyiaj ceev ceev thiab kev them nyiaj tam sim no. Tus neeg sawv cev ntawm high-voltage fast charging yog Qualcomm QuickCharge fast charging technology. 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, thiab 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 lub zog hluav taws xob ceev ceev, qhov siab tshaj plaws tam sim no tsis tshaj 3A.
Tus neeg sawv cev ntawm qhov tsawg-voltage thiab high-tam sim no them ceev daws teeb meem yog OPPO' s VOOC flash charging, uas siv lub zog them ntawm li 20W ntawm qhov ntsuas 5V / 4A, thiab ntsuas lub zog them tuaj yeem ncav cuag ntau dua. mas 19w. Nws yog lub tshuab them ceev tshaj plaws tam sim no. Raws li qhov tseeb Nyob rau hauv cov nqe lus ntawm kev them nyiaj, OPPO' s VOOC flash charging thev naus laus zis ua kom muaj cua sov tsawg heev thaum lub sijhawm them nyiaj, thiab lub cev tsuas yog sov.
Hauv ob xyoos dhau los, nrog rau kev loj hlob ntawm kev them nyiaj ceev thev naus laus zis, feem ntau them sai sai (flash charging) tau siv cov kev daws teeb meem uas tsis tshua muaj hluav taws xob thiab siab tam sim no, suav nrog Huawei' cov kev daws teeb meem ceev ceev, uas. tau hloov los ntawm high-voltage fast charging mus rau low-voltage high-tam sim no them ceev ceev.
Qualcomm' s QC 4+ yog ib qho ntawm ob peb txoj kev them nqi ceev uas tseem hais kom them cov nqi hluav taws xob ceev ceev. Hais tias qhov twg ntawm ob qhov kev daws teeb meem ceev ceev yog qhov zoo dua, cov kev daws teeb meem qis thiab siab tam sim no yog qhov zoo dua. Qhov pom tseeb tshaj plaws txhua hnub yog kev them nyiaj ceev. Nyob rau tib lub sijhawm, tus nqi calorific ntawm kev them nyiaj kuj tsawg.
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 sib tw cov ntaub ntawv no, yog li lub zog hloov dua siab tshiab yog siab dua thaum them lub xov tooj ntawm tes nrog lub zog qis thiab siab tam sim no.
Vim hais tias feem ntau ntawm lub zog poob thaum lub sij hawm them nqi yog nyob rau hauv lub tshav kub tiam, qhov tsawg dua lub tshav kub tiam, lub siab dua conversion efficiency, thaum lub high-voltage fast charging tov tsis muaj qhov zoo dua, thiab lub tshav kub generated thaum lub sij hawm them nqi yog. tseem ceeb dua.
Ntxiv rau qhov qis-voltage 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, thiab qhov voltage thiab tam sim no tuaj yeem nce me ntsis kom ua tiav tib lub zog them.
Qualcomm' s QuickCharge ceev them txhawb nqa qhov no. Piv txwv li, qhov tseeb QC 4+ txhawb nqa 12V / 2.25A ceev ceev thiab tseem muaj 9V / 3A iav, tab sis txawm tias txoj kev cuam tshuam no tsis tas yuav muaj lub zog hloov pauv. Muaj qhov qis-voltage ceev ceev thiab siab, vim li cas Qualcomm hais kom them nyiaj ceev ceev, tus sau tsis paub.
Nws tuaj yeem pom los ntawm cov saum toj no tias txawm hais tias muaj ntau lub npe ntawm cov kev daws teeb meem ceev ceev ntawm kev ua lag luam, cov kev daws teeb meem ceev ceev tiag tiag tsuas yog high-voltage fast charging thiab high-tam sim no them ceev. Thaum lub fuselage muaj cua sov tsawg thiab lwm yam zoo, nws pib kis maj mam.
Nyob rau hauv lub neej yav tom ntej, nrog rau kev tawg ntawm technology, tej zaum yuav muaj ib tug heev ceev ceev kev daws teeb meem nrog high voltage thiab siab tam sim no.
