▍ Daim ntawv pov thawj CB yog dab tsi?
IECEE CB yog thawj txoj hauv kev thoob ntiaj teb rau kev sib koom ua ke ntawm cov khoom siv hluav taws xob kev nyab xeeb kev xeem ntawv ceeb toom. NCB (National Certification Body) ncav cuag ntau qhov kev pom zoo, uas ua rau cov tuam txhab tau txais daim ntawv pov thawj hauv tebchaws los ntawm lwm lub teb chaws cov tswv cuab raws li CB cov tswv yim raws li kev hloov pauv ib qho ntawm NCB daim ntawv pov thawj.
CB daim ntawv pov thawj yog ib daim ntawv pov thawj CB raws li daim ntawv tso cai NCB, uas yog qhia rau lwm tus NCB tias cov khoom kuaj kuaj ua raws li cov qauv yuav tsum tau ua.
Raws li hom ntawv tshaj tawm, CB daim ntawv tshaj tawm teev cov kev xav tau los ntawm IEC tus qauv khoom los ntawm cov khoom. CB daim ntawv tshaj tawm tsis yog tsuas yog muab cov txiaj ntsig ntawm txhua qhov kev ntsuas uas xav tau, ntsuas, tshawb xyuas, tshuaj xyuas thiab kev ntsuas nrog qhov tseeb thiab tsis meej, tab sis kuj suav nrog cov duab, daim duab kos duab, duab thiab cov lus piav qhia ntawm cov khoom. Raws li txoj cai ntawm CB scheme, CB daim ntawv tshaj tawm yuav tsis siv mus txog thaum nws nthuav tawm nrog CB daim ntawv pov thawj ua ke.
▍ Vim li cas peb thiaj xav tau CB Certification?
- Ncaj nraimlylees paubzej or pom zooedlos ntawmtus tswv cuablub teb chaws
Nrog CB daim ntawv pov thawj thiab CB xeem daim ntawv tshaj tawm, koj cov khoom tuaj yeem raug xa tawm mus rau qee lub tebchaws ncaj qha.
- Hloov mus rau lwm lub tebchaws daim ntawv pov thawj
Daim ntawv pov thawj CB tuaj yeem hloov pauv ncaj qha mus rau daim ntawv pov thawj ntawm nws cov tswvcuab hauv tebchaws, los ntawm kev muab CB daim ntawv pov thawj, daim ntawv pov thawj kev xeem thiab cov ntawv xeem sib txawv (thaum muaj feem xyuam) yam tsis tau rov ua dua qhov kev xeem, uas tuaj yeem txo lub sijhawm ua haujlwm ntawm kev lees paub.
- Xyuas kom muaj kev nyab xeeb ntawm cov khoom
CB daim ntawv pov thawj kuaj xyuas cov khoom siv tsim nyog thiab pom tau tias muaj kev nyab xeeb thaum siv tsis raug. Cov khoom muaj ntawv pov thawj ua pov thawj qhov txaus siab ntawm qhov yuav tsum tau muaj kev nyab xeeb.
▍ Vim li cas MCM?
● Kev Tsim Nyog:MCM yog thawj daim ntawv tso cai CBTL ntawm IEC 62133 tus qauv tsim nyog los ntawm TUV RH hauv Suav teb av loj.
● Daim ntawv pov thawj thiab kev xeem muaj peev xwm:MCM yog thawj thaj chaw ntawm kev sim thiab ntawv pov thawj thib peb rau IEC62133 tus qauv, thiab tau ua tiav ntau tshaj 7000 roj teeb IEC62133 kev sim thiab CB cov ntaub ntawv rau cov neeg siv khoom thoob ntiaj teb.
● Kev pab txhawb nqa:MCM muaj ntau dua 15 tus kws tshaj lij kws tshaj lij tshwj xeeb hauv kev sim raws li IEC 62133 tus qauv. MCM muab cov neeg siv khoom nrog cov lus qhia dav dav, raug, kaw-voj hom kev txhawb nqa thiab cov kev pabcuam cov ntaub ntawv ua ntej.
Lub koom haum Cellular Telecommunications Industry Association (CTIA) muaj ib daim ntawv pov thawj uas npog cov cell, 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 cov tswv yim. thov cov tswv yim los ntawm cov chaw soj nstuam, cov tuam txhab roj teeb, cov tuam txhab xov tooj ntawm tes, cov tswv lag luam, cov khoom siv 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 nram qab no yog cov kev hloov kho tseem ceeb: Cov kev xav tau rau lub roj teeb / pob subsystem tau ntxiv, cov khoom yuav tsum tau ua raws li tus qauv UL 2054 lossis UL 62133-2 lossis IEC 62133-2 (nrog rau US kev sib txawv). Nws yog tsim nyog sau cia tias yav tas los tsis tas yuav muab cov ntaub ntawv rau pob.
