▍ Daim ntawv pov thawj PSE yog dab tsi?

PSE (Kev Nyab Xeeb 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 ntawv qhia 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.

Tsis ntev los no International Electrotechnical Commission EE tau pom zoo, tso tawm thiab tshem tawm ntau CTL cov kev daws teeb meem ntawm cov roj teeb, uas feem ntau suav nrog cov roj teeb portable daim ntawv pov thawj tus qauv IEC 62133-2, lub zog cia roj teeb daim ntawv pov thawj tus qauv IEC 62619 thiab IEC 63056. Cov hauv qab no yog cov ntsiab lus tshwj xeeb ntawm kev daws teeb meem:
IEC 62133: 2017, IEC 62133: 2017 +AMD1: 2021: Tshem tawm lub roj teeb 60Vdc txwv qhov yuav tsum tau muaj .Lub Kaum Ob Hlis 2022, CTL tau tshaj tawm qhov kev daws teeb meem uas qhov hluav taws xob ntawm cov khoom siv roj teeb tsis tuaj yeem tshaj 60Vdc. Tsis muaj cov lus qhia meej txog kev txwv voltage hauv IEC 62133-2, tab sis nws hais txog IEC 61960-3 tus qauv.
Yog vim li cas vim li cas qhov kev daws teeb meem no raug tso tseg los ntawm CTL yog tias "qhov kev txwv siab tshaj ntawm 60Vdc yuav txwv qee cov khoom lag luam los ntawm kev ua raws li cov qauv no, xws li cov cuab yeej hluav taws xob, thiab lwm yam." Ib yam li ntawd, nyob rau hauv qhov kev daws teeb meem ib ntus tshaj tawm thaum lub Kaum Ob Hlis xyoo tas los, nws tau npaj siab tias thaum them nyiaj ntawm txoj kev ntawm Tshooj 7.1.2 (yuav tsum tau them nyiaj ntawm qhov kub thiab txias qhov txwv), txawm hais tias nyob rau hauv Daim Ntawv Ntxiv A.4 ntawm tus qauv nws hais. tias thaum lub sij hawm them nyiaj sab saud / qis qis tsis yog 10 ℃ / 45 ℃, qhov kev cia siab them nyiaj kub yuav tsum yog + 5 ℃ thiab qhov kub them qis yuav tsum yog -5 ℃. Txawm li cas los xij, thaum lub sij hawm sim tiag tiag, kev ua haujlwm ntawm +/- 5 ° C tuaj yeem raug tshem tawm thiab kev them nyiaj tuaj yeem ua tiav raws li qhov ntsuas kub ntawm qhov nruab nrab / qis dua.
Qhov kev daws teeb meem no tau dhau los ntawm lub rooj sib tham CTL xyoo no.
Tam sim no cov tuam txhab roj teeb feem ntau yuav BMS los ntawm cov neeg thib peb, uas yuav ua rau cov chaw tsim khoom roj teeb tsis tuaj yeem nkag siab txog cov ncauj lus kom ntxaws BMS. Thaum tus neeg sawv cev kuaj ua qhov kev ntsuam xyuas kev nyab xeeb los ntawm Annex H ntawm IEC 60730-1, cov chaw tsim khoom tsis tuaj yeem muab cov cai ntawm BMS.
