▍ CTUVus & ETL CERTIFICATION yog dab tsi?

OSHA (Occupational Safety and Health Administration), koom nrog US DOL (Department of Labor), xav kom txhua yam khoom siv hauv chaw ua haujlwm yuav tsum tau kuaj thiab ntawv pov thawj los ntawm NRTL ua ntej muag hauv khw. Cov qauv xeem siv tau suav nrog American National Standards Institute (ANSI) cov qauv; American Society for Testing Material (ASTM) cov qauv, Underwriter Laboratory (UL) cov qauv, thiab lub koom haum kev sib nrig sib lees paub cov qauv.

▍OSHA, NRTL, cTUVus, ETL thiab UL cov ntsiab lus txhais thiab kev sib raug zoo

OSHA:Abbreviation of Occupational Safety and Health Administration. Nws yog kev koom tes ntawm US DOL (Department of Labor).

NRTL:Abbreviation of Nationally Recognized Testing Laboratory. Nws yog tus saib xyuas ntawm lab kev lees paub. Txog tam sim no, muaj 18 lub koom haum thib peb uas tau pom zoo los ntawm NRTL, suav nrog TUV, ITS, MET thiab lwm yam.

cTUV:Daim ntawv pov thawj ntawm TUVRh hauv North America.

ETL:Abbreviation of American Electrical Testing Laboratory. Nws tau tsim nyob rau xyoo 1896 los ntawm Albert Einstein, tus neeg tsim khoom Asmeskas.

UL:Cov ntawv luv ntawm Underwriter Laboratories Inc.

▍ Qhov txawv ntawm cTUVus, ETL & UL

▍ Vim li cas MCM?

● Kev txhawb nqa muag los ntawm kev tsim nyog thiab thev naus laus zis:Raws li lub chaw kuaj neeg ua pov thawj ntawm TUVRH thiab ITS hauv North American Certification, MCM muaj peev xwm ua tau txhua yam kev sim thiab muab kev pabcuam zoo dua los ntawm kev sib pauv tshuab ntsej muag.

● Kev txhawb nqa nyuaj los ntawm kev siv tshuab:MCM tau nruab nrog tag nrho cov khoom siv ntsuas rau cov roj teeb ntawm qhov loj-loj, me me thiab cov haujlwm ua tau zoo (xws li lub tsheb fais fab, lub zog cia, thiab cov khoom siv hluav taws xob digital), muaj peev xwm muab tag nrho cov roj teeb kuaj thiab ntawv pov thawj cov kev pabcuam hauv North America, npog cov qauv. UL2580, UL1973, UL2271, UL1642, UL2054 thiab lwm yam.

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 cov yam ntxwv ntawm thermal runaway ntawm txhua theem thiab cov ntaub ntawv hauv cell.Stage 3 yog theem 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.
