▍ 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?

1. 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.

1. 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.

1. 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.

Thaum Lub Kaum Ob Hlis 29, 2022, GB 31241-2022 "Lithium ion hlwb thiab roj teeb siv hauv cov khoom siv hluav taws xob portable —— Kev nyab xeeb kev qhia tshwj xeeb" tau tshaj tawm, uas yuav hloov pauv version GB 31241-2014. Tus qauv tau teem rau yuav tsum tau ua thaum Lub Ib Hlis 1, 2024.GB 31241 yog thawj Suav cov qauv tsim nyog rau cov roj teeb lithium-ion. Nws tau nyiam ntau ntawm kev lag luam txij li thaum nws tso tawm thiab muaj ntau yam kev siv. Cov roj teeb lithium-ion uas siv rau tus qauv GB 31241 tau siv CQC daim ntawv lees paub yeem, tab sis xyoo 2022 nws tau lees paub tias lawv yuav hloov mus rau CCC daim ntawv pov thawj yuav tsum tau ua. Yog li qhov kev tso tawm tshiab ntawm GB 31241-2022 foreshadows qhov kev tso tawm tom ntej ntawm CCC daim ntawv pov thawj cov cai. Raws li qhov no, cov hauv qab no yog ob qho lus pom zoo ntawm daim ntawv pov thawj roj teeb tam sim no rau cov khoom siv hluav taws xob portable: Rau lub sijhawm, nws tsis pom zoo kom hloov kho CQC daim ntawv pov thawj rau qhov tseeb version. Raws li kev siv cov cai thiab cov kev cai rau CCC daim ntawv pov thawj yuav raug tso tawm sai sai, yog tias koj mus hloov kho CQC daim ntawv pov thawj, koj tseem yuav tau ua qhov hloov tshiab tshiab thaum CCC cov ntawv pov thawj cov cai raug tso tawm. Tsis tas li ntawd, rau daim ntawv pov thawj uas twb muaj lawm, ua ntej qhov teeb meem ntawm CCC daim ntawv pov thawj cov cai, nws raug nquahu kom txuas ntxiv hloov kho thiab tswj qhov siv tau ntawm daim ntawv pov thawj, thiab tshem tawm lawv tom qab tau txais daim ntawv pov thawj 3C.
