▍ SIRIM Certification

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 ntawm 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

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.

▍ SIRIM Certification- Secondary Battery

Lub roj teeb thib ob tam sim no yuav raug lees paub los ntawm kev lees paub 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

▍ Vim li cas MCM?

● 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.

T1 yog thawj qhov kub thiab txias uas lub xov tooj cua sov thiab cov ntaub ntawv sab hauv decompose. Nws tus nqi qhia txog tag nrho cov thermal stability ntawm tes. Cells nrog T1 ntau dua qhov tseem ceeb yog qhov ruaj khov ntawm qhov kub thiab txias. Qhov nce lossis txo ntawm T1 yuav cuam tshuam cov thickness ntawm SEI zaj duab xis. Qhov siab thiab qis kub ntawm cov cell aging yuav txo tus nqi ntawm T1 thiab ua rau lub thermal stability ntawm tes tsis zoo. Kev laus qis qis yuav ua rau kev loj hlob ntawm lithium dendrites, uas ua rau T1 txo qis, thiab kub kub laus yuav ua rau qhov tawg ntawm SEI zaj duab xis, thiab T1 kuj yuav txo.
T2 yog lub siab nyem qhov kub. Lub sij hawm nyem ntawm cov pa roj hauv lub sijhawm tuaj yeem ua kom cov cua sov tuaj yeem ua kom zoo thiab ua kom qeeb ntawm cov thermal runaway.T3 yog qhov ntsuas kub ntawm thermal runaway, thiab qhov pib ntawm tshav kub tso tawm ntawm tes. Nws muaj kev sib raug zoo nrog lub substrate kev ua tau zoo ntawm lub diaphragm. Tus nqi ntawm T3 kuj qhia txog cov thermal tsis kam ntawm cov khoom hauv cell. Ib lub xovtooj nrog T3 siab dua yuav muaj kev nyab xeeb dua nyob rau hauv ntau yam kev tsim txom.
T4 yog qhov kub siab tshaj plaws uas cov hlwb tuaj yeem ncav cuag thaum lub sij hawm thermal khiav. Qhov kev pheej hmoo ntawm thermal runaway kis tau nyob rau hauv lub module lossis roj teeb system tuaj yeem soj ntsuam ntxiv los ntawm kev ntsuam xyuas tag nrho cov hluav taws xob tsim hluav taws xob (ΔT = T4 -T3) thaum lub sij hawm thermal khiav ntawm lub xov tooj ntawm tes. Yog tias cov cua sov siab dhau lawm, nws yuav ua rau thermal khiav ntawm cov hlwb nyob ib puag ncig, thiab nws thiaj li nthuav tawm mus rau tag nrho cov module.
