▍ 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.

Raws li cov ntaub ntawv tsis ntev los no tau tshaj tawm los ntawm Tuam Tshoj Ministry of Emergency Management, 640 qhov xwm txheej hluav taws kub ntawm lub zog tshiab tau tshaj tawm nyob rau thawj peb lub hlis twg xyoo 2022, nce 32% nyob rau tib lub sijhawm xyoo tas los, nrog qhov nruab nrab ntawm 7 hluav taws kub ib hnub. Tus sau tau ua qhov kev txheeb xyuas los ntawm lub xeev ntawm qee qhov hluav taws kub EV, thiab pom tias tus nqi hluav taws xob hauv lub xeev tsis siv, lub xeev tsav tsheb thiab lub xeev them nqi ntawm EV tsis txawv ntawm ib leeg, raws li qhia hauv daim duab hauv qab no. Tus kws sau ntawv yuav ua ib qho kev ntsuam xyuas yooj yim ntawm qhov ua rau hluav taws kub hauv peb lub xeev no thiab muab cov tswv yim tsim kev nyab xeeb.
Txawm hais tias qhov xwm txheej twg ua rau lub roj teeb hluav taws kub lossis tawg, lub hauv paus ua rau yog qhov luv luv hauv lossis sab nraud ntawm tes, uas ua rau thermal khiav ntawm lub cell. Tom qab lub thermal runaway ntawm ib lub xov tooj ntawm tes, nws thaum kawg yuav ua rau tag nrho cov pob ntes hluav taws yog tias thermal nthuav tawm tsis tuaj yeem zam vim yog cov qauv tsim ntawm module lossis pob. Ua rau sab hauv lossis sab nraud luv luv ntawm lub xov tooj ntawm tes yog (tab sis tsis txwv rau): overheating, overcharge, tshaj tawm, mechanical force (crush, shock), circuit aging, metal particles into the cell in production process, etc.
