▍ 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.

Kev nyab xeeb ntawm lub zog cia system yog ib qho kev txhawj xeeb. Raws li ib qho ntawm cov khoom tseem ceeb ntawm lub zog cia, kev nyab xeeb ntawm lithium-ion roj teeb yog qhov tseem ceeb tshwj xeeb. Raws li kev ntsuas thermal runaway tuaj yeem ntsuas ncaj qha qhov kev pheej hmoo ntawm hluav taws kub tshwm sim hauv lub zog cia, ntau lub teb chaws tau tsim cov kev sim sib xws hauv lawv cov qauv los ntsuas qhov kev pheej hmoo ntawm thermal runaway. Piv txwv li, IEC 62619 tawm los ntawm International Electrotechnical Commission (IEC) qhia txog txoj kev nthuav tawm los ntsuas qhov cuam tshuam ntawm thermal runaway ntawm tes; Suav teb chaws tus qauv GB / T 36276 yuav tsum tau thermal runaway ntsuam xyuas ntawm tes thiab thermal runaway xeem ntawm lub roj teeb module; Lub US Underwriters Laboratories (UL) luam tawm ob tus qauv, UL 1973 thiab UL 9540A, ob qho tib si ntsuas cov teebmeem thermal runaway. UL 9540A yog tsim tshwj xeeb los ntsuas los ntawm plaub theem: cell, module, txee, thiab cua sov propagation ntawm theem installation. Cov txiaj ntsig ntawm thermal runaway test tsis tuaj yeem ntsuas qhov kev nyab xeeb tag nrho ntawm lub roj teeb, tab sis tseem tso cai rau peb kom nkag siab sai sai ntawm thermal runaway ntawm cov hlwb, thiab muab cov kev sib piv rau kev nyab xeeb tsim ntawm cov hlwb nrog cov tshuaj zoo sib xws. Cov pab pawg hauv qab no ntawm kev sim cov ntaub ntawv rau thermal runaway yog rau koj kom nkag siab txog cov yam ntxwv ntawm thermal runaway ntawm txhua theem thiab cov ntaub ntawv hauv cell.
Theem 3 yog theem ntawm electrolyte decomposition (T1 ~ T2). Thaum kub txog 110 ℃, cov electrolyte thiab cov electrode tsis zoo, nrog rau cov electrolyte nws tus kheej yuav tshwm sim cov tshuaj tiv thaiv decomposition, ua kom muaj roj ntau. Cov roj tsis tu ncua ua rau lub siab nyob rau hauv lub cell nce sharply, ncav lub siab nyem tus nqi, thiab lub gas exhausting mechanism qhib (T2). Lub sijhawm no, ntau cov pa roj, electrolytes thiab lwm yam khoom tso tawm, tshem tawm ib feem ntawm cov cua sov, thiab qhov kub thiab txias nce yuav tsis zoo.
