▍ Daim ntawv pov thawj PSE yog dab tsi?

PSE (Cov Khoom Siv Kev Nyab Xeeb ntawm Cov Khoom Siv Hluav Taws Xob & Khoom Siv) yog qhov yuav tsum tau ua ntawv pov thawj hauv Nyij Pooj. Nws tseem yog hu ua 'Compliance Inspection' uas nws yog qhov yuav tsum tau ua lag luam nkag mus rau cov khoom siv hluav taws xob. PSE daim ntawv pov thawj yog tsim los ntawm ob ntu: EMC thiab cov khoom ruaj ntseg thiab nws kuj yog ib qho tseem ceeb ntawm Nyiv txoj cai lij choj kev nyab xeeb rau cov khoom siv hluav taws xob.

▍ Daim ntawv pov thawj Standard rau lithium roj teeb

Txhais lus rau METI Ordinance for Technical Requirements (H25.07.01), Appendix 9, Lithium ion secondary batteries

▍ Vim li cas MCM?

● Cov chaw tsim nyog: MCM tau nruab nrog cov chaw tsim nyog uas tuaj yeem ua raws li tag nrho cov qauv ntsuas PSE thiab ua cov kev xeem suav nrog kev yuam kom luv luv luv Circuit Court thiab lwm yam. .

● Kev pab txhawb nqa: MCM muaj ib pab neeg ua haujlwm ntawm 11 tus kws tshaj lij engineers tshwj xeeb hauv PSE cov qauv kev xeem thiab cov kev cai, thiab muaj peev xwm muab cov kev cai PSE tshiab thiab xov xwm rau cov neeg siv khoom raws li qhov tseeb, meej thiab sai.

● Muaj ntau hom kev pabcuam: MCM tuaj yeem tshaj tawm cov ntaub ntawv ua lus Askiv lossis Nyij Pooj kom tau raws li cov neeg xav tau. Txog tam sim no, MCM tau ua tiav ntau dua 5000 PSE cov haujlwm rau cov neeg siv khoom tag nrho.

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.
