UL1973 CSDS PROPOSAL hauv lub Tsib Hlis,
lwj 1973,

▍ 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 Tsib Hlis 21, 2021, UL official lub vev xaib tau tshaj tawm cov ntsiab lus tawm tswv yim tshiab ntawm UL1973 roj teeb tus qauv rau chaw nres tsheb, tsheb thauj khoom siv hluav taws xob thiab lub teeb rail (LER) daim ntawv thov. Hnub kawg rau kev tawm tswv yim yog Lub Xya Hli 5, 2021. Cov hauv qab no yog 35 lub tswv yim:
1. Kev sim ntawm Modules thaum lub sij hawm luv luv Circuit Court test.
2. Kev kho kho.
3. Ntxiv qhov kev zam rau General Performance Section rau lub sij hawm xeem rau lithium ion hlwb
los yog roj teeb.
4. Kev hloov kho rau Table 12.1, Lus Cim (d) rau kev poob ntawm kev tswj hwm thawj zaug.
5. Ntxiv qhov Kev Zam Txim Rau Qhov Kev Ntsuam Xyuas Kev Nyuaj Siab SOC.
6. Ntxiv qhov kev zam rau kev siv sab nraum zoov nkaus xwb nyob rau hauv ib qho Cell Failure Design Tolerance test.
7. Tsiv tag nrho lithium cell yuav tsum tau mus rau UL 1973.
8. Ntxiv cov kev cai rau repurposing roj teeb.
9. Kev qhia meej ntawm cov kua qaub roj teeb uas yuav tsum tau ua.
10. Ntxiv rau Lub Tsheb Pab Txhawb Lub Hwj Chim Kev Xav Tau.
