USB-B interface daim ntawv pov thawj yuav raug tshem tawm hauv qhov tshiab ntawm CTIA IEEE 1725
USB-B interface daim ntawv pov thawj yuav raug tshem tawm hauv qhov tshiab ntawmCTIATIAB SA 1725,
CTIA,
▍ KC yog dab tsi?
Txij thaum 25thLub Yim Hli, 2008, Kaus Lim Kauslim Ministry of Knowledge Economy (MKE) tshaj tawm tias National Standard Committee yuav ua ib lub teb chaws tshiab daim ntawv pov thawj - lub npe KC cim hloov Korean Certification thaum lub sij hawm lub Xya hli ntuj 2009 thiab Kaum Ob Hlis 2010. Cov khoom siv hluav taws xob muaj ntawv pov thawj kev nyab xeeb scheme (KC Certification) yog qhov yuav tsum tau ua thiab kev tswj hwm tus kheej kev nyab xeeb kev pom zoo raws li Kev Tswj Xyuas Hluav Taws Xob Hluav Taws Xob Kev Nyab Xeeb Txoj Cai, ib lub tswv yim uas tau lees paub kev nyab xeeb ntawm kev tsim khoom thiab muag.
Qhov txawv ntawm qhov yuav tsum tau ntawv pov thawj thiab kev tswj tus kheej( yeem)kev lees paub kev nyab xeeb:
Rau kev tswj xyuas kev nyab xeeb ntawm cov khoom siv hluav taws xob, KC ntawv pov thawj tau muab faib ua kev tswj hwm tus kheej thiab kev tswj hwm tus kheej (daim ntawv pov thawj) kev nyab xeeb raws li kev faib tawm ntawm kev phom sij ntawm cov khoom.Cov ntsiab lus ntawm Kev Tswj Xyuas Cov Ntawv Pov Thawj yog siv rau cov khoom siv hluav taws xob uas nws cov qauv thiab cov txheej txheem ntawm daim ntawv thov yuav ua rau Qhov tshwm sim txaus ntshai lossis teeb meem xws li hluav taws kub, hluav taws xob poob siab. Thaum cov ntsiab lus ntawm kev tswj hwm tus kheej (daim ntawv pov thawj) kev nyab xeeb yog siv rau cov khoom siv hluav taws xob uas nws cov qauv thiab cov txheej txheem ntawm daim ntawv thov tsis tuaj yeem ua rau muaj kev phom sij loj lossis cuam tshuam xws li hluav taws xob, hluav taws xob poob siab. Thiab qhov txaus ntshai thiab teeb meem tuaj yeem tiv thaiv los ntawm kev sim cov khoom siv hluav taws xob.
▍ Leej twg tuaj yeem thov rau KC ntawv pov thawj:
Txhua tus neeg raug cai lossis cov neeg nyob hauv tsev thiab txawv teb chaws uas koom nrog hauv kev tsim khoom, sib dhos, ua cov khoom siv hluav taws xob.
▍ Cov txheej txheem thiab txheej txheem ntawm kev pov thawj kev nyab xeeb:
Thov rau KC ntawv pov thawj nrog cov khoom lag luam tus qauv uas tuaj yeem muab faib ua cov qauv yooj yim thiab cov qauv series.
Txhawm rau kom paub meej hom qauv thiab tsim cov khoom siv hluav taws xob, ib lub npe khoom tshwj xeeb yuav raug muab raws li nws txoj haujlwm sib txawv.
▍ KC ntawv pov thawj rau Lithium roj teeb
- KC daim ntawv pov thawj tus qauv rau lithium roj teeb:KC62133:2019
- Khoom Scope ntawm KC ntawv pov thawj rau lithium roj teeb
A. Secondary lithium roj teeb rau siv nyob rau hauv daim ntawv thov portable los yog tshem tau cov khoom
B. Cell tsis raug KC daim ntawv pov thawj txawm tias muag lossis sib sau ua ke hauv cov roj teeb.
C. Rau cov roj teeb uas siv rau hauv cov khoom siv hluav taws xob los yog UPS (tsis cuam tshuam lub zog hluav taws xob), thiab lawv lub zog uas ntau dua 500Wh yog dhau qhov kev txwv.
D. Lub roj teeb uas nws lub zog ntim qis dua 400Wh / L los rau hauv cov ntawv pov thawj txij li 1st, Lub Plaub Hlis 2016.
▍ Vim li cas MCM?
● MCM khaws kev koom tes nrog Kaus Lim Kauslim cov chaw sim, xws li KTR (Korea Testing & Research Institute) thiab muaj peev xwm muab cov kev daws teeb meem zoo tshaj plaws nrog kev ua haujlwm siab thiab muaj txiaj ntsig ntxiv rau cov neeg siv khoom los ntawm lub sijhawm ua cov txheej txheem kuaj, ntawv pov thawj nqi.
● KC ntawv pov thawj rau rechargeable lithium roj teeb tuaj yeem tau txais los ntawm kev xa daim ntawv pov thawj CB thiab hloov mus rau hauv daim ntawv pov thawj KC. Raws li CBTL raws li TÜV Rheinland, MCM tuaj yeem muab cov ntawv ceeb toom thiab daim ntawv pov thawj uas tuaj yeem thov rau kev hloov pauv ntawm KC daim ntawv pov thawj ncaj qha. Thiab lub sijhawm ua haujlwm tuaj yeem ua kom luv yog tias thov CB thiab KC tib lub sijhawm. Dab tsi ntxiv, tus nqi cuam tshuam yuav zoo dua.
Lub koom haum Cellular Telecommunications Industry Association (CTIA) muaj cov txheej txheem ntawv pov thawj npog cov hlwb, roj teeb, adapters thiab hosts thiab lwm yam khoom siv hauv kev sib txuas lus wireless (xws li xov tooj ntawm tes, laptops). Ntawm lawv, CTIA ntawv pov thawj rau cov hlwb yog tshwj xeeb tshaj yog nruj. Dhau li ntawm qhov kev ntsuam xyuas ntawm kev nyab xeeb kev ua tau zoo, CTIA tseem tsom rau cov qauv tsim ntawm cov hlwb, cov txheej txheem tseem ceeb ntawm cov txheej txheem tsim khoom thiab nws cov kev tswj kom zoo. Txawm hais tias daim ntawv pov thawj CTIA tsis yog qhov yuav tsum tau ua, cov tswv lag luam loj hauv North America xav kom lawv cov khoom lag luam kom dhau CTIA daim ntawv pov thawj, yog li ntawv pov thawj CTIA tseem tuaj yeem suav tias yog qhov yuav tsum tau nkag rau North American kev sib txuas lus lag luam.CTIA tus qauv ntawv pov thawj yeej ib txwm xa mus rau IEEE 1725. thiab IEEE 1625 luam tawm los ntawm IEEE (Institute of Electrical and Electronics Engineers). Yav dhau los, IEEE 1725 siv rau cov roj teeb uas tsis muaj cov qauv tsim; thaum IEEE 1625 siv rau cov roj teeb nrog ob lossis ntau dua kev sib txuas. Raws li CTIA cov ntawv pov thawj roj teeb tau siv IEEE 1725 raws li tus qauv siv, tom qab tshaj tawm cov ntawv tshiab ntawm IEEE 1725-2021 hauv 2021, CTIA kuj tau tsim ib pab pawg ua haujlwm los pib ib txoj haujlwm ntawm kev hloov kho CTIA daim ntawv pov thawj scheme.
Pawg neeg ua haujlwm tau thov kev xav los ntawm cov chaw soj nstuam, cov tuam txhab roj teeb, cov tuam txhab xov tooj ntawm tes, cov tuam txhab tsim khoom, cov chaw tsim khoom adapter, thiab lwm yam. Nyob rau lub Tsib Hlis xyoo no, thawj lub rooj sib tham rau CRD (Certification Requirements Document) tau tuav. Thaum lub sij hawm, ib pawg adapter tshwj xeeb tau teeb tsa los tham txog USB interface thiab lwm yam teeb meem sib cais. Tom qab ntau tshaj li ib nrab xyoo, lub rooj sib tham zaum kawg tau tuav lub hli no. Nws lees paub tias daim ntawv pov thawj tshiab ntawm CTIA IEEE 1725 (CRD) yuav raug muab tawm rau lub Kaum Ob Hlis, nrog rau lub sijhawm hloov pauv ntawm rau lub hlis. Qhov no txhais tau hais tias CTIA daim ntawv pov thawj yuav tsum tau ua los ntawm kev siv cov ntawv tshiab ntawm CRD tom qab Lub Rau Hli 2023. Peb, MCM, uas yog ib tug tswv cuab ntawm CTIA's Test Laboratory (CATL), thiab CTIA's Battery Working Group, tau thov kev kho dua tshiab rau txoj kev sim tshiab thiab koom nrog. thoob plaws hauv CTIA IEEE1725-2021 CRD kev sib tham. Cov hauv qab no yog cov kev hloov kho tseem ceeb:
