Cov lus piav qhia ntxaws txog qhov yuam kev hauv luv luv Circuit Court ntawm lithium ion cell,
,

▍ 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.

Lub Hom Phiaj Xeem: txhawm rau simulate luv luv Circuit Court ntawm qhov zoo thiab tsis zoo electrodes, seem particle thiab lwm yam impurities uas yuav nkag mus rau hauv lub cell thaum lub sij hawm tsim khoom. Xyoo 2004, lub laptop roj teeb uas tsim los ntawm lub tuam txhab Japanese tau ntes hluav taws. Tom qab kev soj ntsuam ntxaws txog qhov ua rau lub roj teeb hluav taws xob, nws ntseeg tau tias cov roj teeb lithium ion tau sib xyaw nrog cov hlau me me thaum lub sijhawm tsim khoom, thiab cov roj teeb tau siv vim qhov kub thiab txias. Los yog muaj kev cuam tshuam ntau yam, cov khoom siv hlau tho qhov sib cais ntawm qhov zoo thiab qhov tsis zoo ntawm cov electrodes, ua rau luv luv hauv lub roj teeb, ua rau muaj cua sov ntau ua rau lub roj teeb ntes hluav taws. Txij li thaum sib tov ntawm cov hlau hais nyob rau hauv cov txheej txheem ntau lawm yog ib qho kev huam yuaj, nws yog ib qho nyuaj kom tsis txhob muaj qhov no tshwm sim. Yog li ntawd, ib qho kev sim ua kom simulate lub luv luv Circuit Court tshwm sim los ntawm cov hlau hais piercing lub diaphragm los ntawm "yuam kev short circuit test". Yog tias lub roj teeb lithium ion tuaj yeem ua kom ntseeg tau tias tsis muaj hluav taws kub tshwm sim thaum lub sijhawm kuaj, nws tuaj yeem ua kom ntseeg tau tias txawm tias cov roj teeb sib xyaw hauv cov txheej txheem tsim khoom: cell (tshwj tsis yog lub xov tooj ntawm cov khoom siv hluav taws xob tsis yog kua hluav taws xob). Kev sim ua kom puas tsuaj qhia tau tias kev siv cov roj teeb lithium ion muaj kev nyab xeeb siab. Tom qab kev puas tsuaj xws li ntsia thawv nkag, cua sov (200 ℃), luv luv Circuit Court thiab overcharge (600%), kua electrolyte lithium-ion roj teeb yuav xau thiab tawg. Ntxiv nrog rau qhov nce me ntsis hauv qhov kub thiab txias (<20 ° C), lub roj teeb lub xeev tsis muaj lwm yam teeb meem kev nyab xeeb
