Oct 06, 2022| Fast charging technology loj hloov tshiab, USB PD3.1 tso tawm, txhawb 48V thiab 240W tso zis
Tsis ntev los no, USB PD3.0 tus qauv them ceev tau txais kev hloov kho tshiab kawg. Tus qauv tshiab USB PD3.1 ceev ceev tus qauv yuav txhawb nqa qhov tso zis ntau tshaj plaws ntawm 48V, thiab lub zog them hluav taws xob yog synchronized rau 240W
USB PD3.1 tau tso tawm
Thaum Lub Tsib Hlis 25, lub koom haum USB-IF tau tshaj tawm USB Hom-C Cable thiab Interface Standard V2.1, uas tau hloov kho ntu ntawm lub peev xwm muab hluav taws xob. USB PD3.1 specification yuav yog thawj USB PD3.0 cov ntsiab lus rau hauv Standard Power Range (SPR), lub zog siab tshaj plaws kom 100W tsis hloov; Tib lub sijhawm, Extended Power Range (EPR) txuas ntxiv los ntawm 100W txog 240W.
Raws li cov ntaub ntawv tso tawm los ntawm USB-IF Association, Adjustable Voltage Supply (AVS), los yog Adjustable Voltage Supply (28V, 36V thiab 48V), yog qhov tshiab nyob rau hauv lub zog txuas ntxiv EPR.
Qhov siab tshaj plaws tam sim no tseem tsis hloov pauv ntawm qhov siab tshaj 5A; 100-140W zog yog 28V AVS, qhov hluav taws xob ntau yog 15V-28V; Ntau tshaj 140W txog 180W fais fab tuag yog 36V AVS, qhov hluav taws xob ntau yog 15V-36V; Ntau tshaj 180W txog 240W yog 48V AVS, thiab qhov hluav taws xob ntau yog 15V-48V.
Raws li tus qauv USB PD3.1, USB hom-c cables tau muab faib ua 20V tib yam cables thiab 50V EPR cables. Yog hais tias lub hwj chim tso zis ntau tshaj 100W, tsis yog tsuas yog 5A Cable ntawm EPR (ntxiv lub zog) yuav tsum tau, tab sis kuj yuav tsum tau EPR cov ntaub ntawv tshwj xeeb tuav tes ntawm qhov chaw, Sink thiab Cable yuav tsum tau nkag mus rau EPR los ntawm SPR. Yog hais tias lub cable yog Captive cable txuas rau lub charger, tsuas yog yuav tsum tau tuav tes ntawm qhov chaw thiab lub dab dej.
Txij li thaum qib voltage tau nce siab heev, kev nyab xeeb tseem ceeb heev. EPR xav tau cov qauv kev nyab xeeb siab dua rau cov khoom sib txuas thiab cov cables. Kev saib xyuas yuav tsum tau them rau IEC 62368 txoj cai ntawm Kev Siv Hluav Taws Xob Txwv Txwv (LPS).
Nws yog ib nqi sau cia hais tias nyob rau hauv lub formulation ntawm USB PD3.1 specification, Huawei, Xiaomi, Lishun Precision, Huinengtai thiab ntau lwm yam domestic tuam txhab uas muag tau nquag koom nyob rau hauv nws thiab ua ib qho tseem ceeb pab rau tus qauv tshiab, uas tau sau rau hauv lub lag luam directory ntawm txheem txheej txheem.
Usb-if, lub npe tag nrho ntawm USB Implementer Forum, tau tsim muaj xyoo 1995 thiab yog lub hauv paus hauv Tebchaws Meskas. Nws tau koom tes los ntawm Apple, HP, Intel Intel, Microsoft Microsoft, Renesas, ST stmicroelectronics, TI Texas Instruments thiab lwm lub tuam txhab.
Usb-yog tias yog lub koom haum tsis muaj txiaj ntsig tau mob siab rau kev txhim kho Universal Serial Bus technology thiab kev txhawb nqa ntawm nws daim ntawv thov. Los ntawm kev muab cov qauv thiab kev sib koom ua ke sib txuas lus tshwj xeeb, USB ua rau kev sib txuas thiab kev sib kis ntawm cov khoos phis tawj thiab cov khoom siv peripheral yooj yim thiab yooj yim, tshem tawm qhov tsis yooj yim ntawm kev siv daim npav sab nraud lossis cov keyboards. Feem ntau, cov ntaub ntawv cov khoom siv nrog USB specifications npog ntau yam khoom, xws li khoos phis tawj, koob yees duab, tshuab luam ntawv, keyboards, nas, cov ntxaij vab tshaus, cov khoom siv hauv network, xov tooj ntawm tes thiab ntau yam khoom siv hluav taws xob tshiab.
