Hnub ua ntej Xiaomi 12 Series tso tawm, Xiaomi txuas ntxiv nthuav tawm ntau ntxiv txog lawv cov khoom lag luam tshiab.
Los ntawm kev tso tawm thawj tiam ntawm kev them nyiaj ceev los ntawm Xiaomi hauv 2019, mus rau qhov kev them nyiaj ceev ceev ntawm MIX 4, Wired charging ceev nce los ntawm 7.5 lub sij hawm thiab cov wireless charging ceev tau nce los ntawm 12 lub sij hawm. Tam sim no nrog cov khoom siv tam sim no ntawm kev ua lag luam, suav nrog chargers tuaj yeem them cov xov tooj hauv 15 feeb. Nrog rau qhov nce ntawm kev them nqi nrawm thiab txo lub sijhawm them, smartphone tus neeg siv tus cwj pwm ntawm kev them nyiaj thaum hmo ntuj hloov mus rau them rau ya.
Yuav kom ua tiav kev kub ceev ntawm kev them nyiaj, Xiaomi set ceev them raws li ib qho kev taw qhia tseem ceeb hauv 2019. Xiaomi tsim plaub lub chaw tshawb fawb thiab kev loj hlob sib txawv, Hauv peb xyoos Xioami thov rau ntau tshaj 800 patents thiab tso tawm lab ntawm cov khoom siv nruab nrog ceev them systems.
120W tib lub xov tooj daws teeb meem los txhim kho roj teeb lub neej, lub teeb thiab nyias
Smartphones nrog wired charging ceev txog 120W siv dual-cell system tsis muaj kev zam. Tus nqi ntawm kev kub ceev them yog mus txo kev siv ntawm cov qhov chaw sab hauv ntawm tus xov tooj. Cov dual-cell roj teeb thaum piv rau tib lub roj teeb ntawm tes, muaj peev xwm yog hais txog % 3 mus rau% 4 qis tshaj li ib lub xov tooj, txawm tias ntau dua li cov roj teeb dual-cell xav tau lwm lub nti rau kev them nyiaj thiab vim tias qhov ua tau zoo no yuav ua rau muaj kev cuam tshuam. pov tseg ntawm% 3 mus rau 4% ntawm lub zog. Ib-cell roj teeb tuaj yeem kho tau cov teeb meem no tab sis nws ntsib a kev sib tw loj kom them zog ntxiv siab tshaj 100W.
Lub hom phiaj ntawm Xiaomi yog kom ua tiav tshuav nyiaj li cas zoo tshaj nruab nrab ntawm lub roj teeb lub neej thiab kev them nyiaj ua haujlwm thiab ua kom tiav Ib leeg-cell 120W wired ceev them.
Surge P1 thiab 120W ib leeg-cell ceev them
Thaum ub ib leeg-cell ceev them daws teeb meem, los hloov 20V voltage input mus rau hauv lub 5V voltage, ib tug series ntawm parallel Circuit Court ntawm 5 txawv cov twj tso kua mis yog yuav tsum tau. Vim li no lub curcuit tsim kub ntau, nws yog tsis yooj yim sua them nqi ntawm tag nrho lub zog rau lub sijhawm ntev thiab nws yog txawm nyuaj dua kom ua tiav 120W ceev them, uas yog tsis tsim nyog rau Xiaomi.
Yuav kho dua tshiab tag nrho them architecture, nws yog ib qho tsim nyog yuav tau redefine lub luag hauj lwm ntawm lub fast charging nti. Lub hauv paus ntawm Xiaomi's 120W them yog ob tug self-tsim ntse charging chips; lub npe hu ua Surge P1. Surge P1 yuav siv sij hawm dhau cov qauv ntawm cov tsoos 5 lub twj tso kua mis thiab hloov cov hluav taws xob high-voltage fais fab tso rau hauv lub xov tooj ntawm tes mus rau hauv ib qho loj tam sim no uas tuaj yeem raug them ncaj qha rau lub roj teeb zoo dua.
Raws li kev lag luam thawj zaug discrete charging chip, Surge P1 muaj ib qho ultra-siab npaum architecture. "Kev ua tau zoo ntawm cov resonant topology yog siab li 97.5%, qhov ua tau zoo ntawm cov tsis-resonant topology yog 96.8%, thiab cov cua sov poob yog txo los ntawm 30%.
Surge P1 ua haujlwm hloov dua siab tshiab: ib txwm siv lub twj tso kua mis voltage converters tsuas yog xav tau ob hom kev ua haujlwm (kev hloov pauv, dhau mus), thaum Surge P1 xav tau kev txhawb nqa 1: 1, 2: 1 thiab 4: 1 hloov pauv hom, thiab txhua hom yuav tsum tau txhawb nqa dual conduction, uas txhais tau hais tias tag nrho ntawm 15 permutations thiab kev sib txuas ntawm hom hloov pauv, 7 npaug ntau dua li cov twj tso kua mis voltage converters. Cov 1: 1 mode ua rau lub vijtsam ntawm kev them nyiaj ntau dua, lub 2: 1 mode yog sib xws nrog ntau chargers thiab cov 4:1 xav tau rau 120W them. Rov qab 1:4 thiab 1:2 hom kev pab txhawb nqa high-power reverse charging.
4: 1 charging chip nrog lub siab tshaj plaws them nqi thiab tsim nyuaj tshaj plaws
Nyob rau tib lub sijhawm, Surge P1 kuj tseem yog 4: 1 charging chip nrog lub siab tshaj them efficiency los ntawm Xiaomi, uas tuaj yeem ua tiav ultra-siab zog ceev ntawm 0.83W / mm², LDMOS kuj mus txog qhov kev lag luam-ua ultra-low 1.18mΩmm² RSP. Cov Surge P1 nti xav tau peb qhov sib txawv FLY capacitor nrog qhov sib txawv voltage kuj. Txhua lub capacitor xav tau ib qho kev ywj pheej luv luv Circuit Court tiv thaiv Circuit Court thiab txhua hom kev khiav hauj lwm yuav tsum tau nruj me ntsis tswj lub precharge voltage, tus naj npawb ntawm lub hwj chim raj yog ze rau ob tsoos charge twj, thiab vim hais tias ntawm qhov nce nyob rau hauv topology tsim thiab functional complexity, txhua. Surge P1 yuav tsum dhau ntau tshaj 2500 kev xeem ua ntej tawm hauv lub hoobkas, uas yog ntau dua dua li cov twj tso kua mis ib txwm muaj.
xaus
Thaum kawg, nrog Surge P1 ntiTxoj kev pab, Xiaomi muaj peev xwm ua kom yooj yim rau kev them nqi hluav taws xob thiab tib lub sijhawm ultra-siab efficiency of Surge P1 txhais tau hais tias kev tsim hluav taws xob yuav tsawg dua thiab lub zog them tag nrho tuaj yeem txuas ntxiv mus ntev dua.
Lub neej tom ntej xiaomi 12 pro yog lub thawj smartphone los ntawm Xiaomi yuav tsum tau nruab nrog Surge P1Cov. Nws txhawb nqa 120W xaim them, 50W wireless txuas them nyiaj thiab 10W rov qab wireless tsub.
Hauv kev lag luam them nyiaj ceev, Xiaomi ua ntej ntawm lwm cov tuam txhab, siv tus kheej tsim them chips. Peb yuav paub ntau ntxiv txog Surge P1 thiab nws cov peev xwm ntawm Hlis ntuj nqeg 28!
