Hluav taws xob tsheb,
Rau kev ruaj ntseg ntawm tib neeg thiab khoom vaj khoom tsev, Malaysia tsoom fwv tsim cov khoom pov thawj cov tswv yim thiab tso saib xyuas cov khoom siv hluav taws xob, cov ntaub ntawv & multimedia thiab cov ntaub ntawv tsim kho. Cov khoom tswj tau tuaj yeem xa tawm mus rau Malaysia tsuas yog tom qab tau txais daim ntawv pov thawj khoom pov thawj thiab daim ntawv lo.
SIRIM QAS, ib lub koom haum ua lag luam tag nrho ntawm Malaysian Institute of Industry Standards, yog tib lub chaw muab ntawv pov thawj ntawm Malaysian lub koom haum tswj hwm hauv tebchaws (KDPNHEP, SKMM, thiab lwm yam).
Daim ntawv pov thawj roj teeb thib ob yog tsim los ntawm KDPNHEP (Malaysian Ministry of Domestic Trade thiab Consumer Affairs) raws li ib qho kev lees paub. Tam sim no, cov chaw tsim khoom, cov khoom lag luam thiab cov neeg lag luam tuaj yeem thov daim ntawv pov thawj rau SIRIM QAS thiab thov rau kev sim thiab ntawv pov thawj ntawm cov roj teeb thib ob nyob rau hauv hom ntawv pov thawj.
Lub roj teeb thib ob tam sim no raug lees paub los ntawm daim ntawv pov thawj tab sis nws yuav nyob rau hauv qhov yuav tsum tau lees paub sai sai. Hnub kawg uas yuav tsum tau ua yog nyob rau lub sijhawm tshaj tawm Malaysian. SIRIM QAS twb tau pib lees txais daim ntawv thov.
Secondary roj teeb ntawv pov thawj Standard: MS IEC 62133: 2017 los yog IEC 62133: 2012
● Tsim kom muaj kev sib pauv tswv yim zoo thiab kev sib pauv xov xwm nrog SIRIM QAS uas tau muab ib tus kws tshaj lij los daws cov haujlwm MCM thiab cov lus nug nkaus xwb thiab qhia cov ntaub ntawv tseeb tseeb ntawm thaj chaw no.
● SIRIM QAS lees paub MCM cov ntaub ntawv xeem kom cov qauv tuaj yeem kuaj hauv MCM es tsis txhob xa mus rau Malaysia.
● Los muab kev pabcuam ib-nres rau Malaysian ntawv pov thawj ntawm roj teeb, adapters thiab xov tooj ntawm tes.
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.
