▍ Daim ntawv pov thawj CB yog dab tsi?

IECEE CB yog thawj txoj hauv kev thoob ntiaj teb rau kev sib koom ua ke ntawm cov khoom siv hluav taws xob kev nyab xeeb kev xeem ntawv ceeb toom. NCB (National Certification Body) ncav cuag ntau qhov kev pom zoo, uas ua rau cov tuam txhab tau txais daim ntawv pov thawj hauv tebchaws los ntawm lwm lub teb chaws cov tswv cuab raws li CB cov tswv yim raws li kev hloov pauv ib qho ntawm NCB daim ntawv pov thawj.

CB daim ntawv pov thawj yog ib daim ntawv pov thawj CB raws li daim ntawv tso cai NCB, uas yog qhia rau lwm tus NCB tias cov khoom kuaj kuaj ua raws li cov qauv yuav tsum tau ua.

Raws li hom ntawv tshaj tawm, CB daim ntawv tshaj tawm teev cov kev xav tau los ntawm IEC tus qauv khoom los ntawm cov khoom. CB daim ntawv tshaj tawm tsis yog tsuas yog muab cov txiaj ntsig ntawm txhua qhov kev ntsuas uas xav tau, ntsuas, tshawb xyuas, tshuaj xyuas thiab kev ntsuas nrog qhov tseeb thiab tsis meej, tab sis kuj suav nrog cov duab, daim duab kos duab, duab thiab cov lus piav qhia ntawm cov khoom. Raws li txoj cai ntawm CB scheme, CB daim ntawv tshaj tawm yuav tsis siv mus txog thaum nws nthuav tawm nrog CB daim ntawv pov thawj ua ke.

▍ Vim li cas peb thiaj xav tau CB Certification?

1. Ncaj nraimlylees paubzej or pom zooedlos ntawmtus tswv cuablub teb chaws

Nrog CB daim ntawv pov thawj thiab CB xeem daim ntawv tshaj tawm, koj cov khoom tuaj yeem raug xa tawm mus rau qee lub tebchaws ncaj qha.

1. Hloov mus rau lwm lub tebchaws daim ntawv pov thawj

Daim ntawv pov thawj CB tuaj yeem hloov pauv ncaj qha mus rau daim ntawv pov thawj ntawm nws cov tswvcuab hauv tebchaws, los ntawm kev muab CB daim ntawv pov thawj, daim ntawv pov thawj kev xeem thiab cov ntawv xeem sib txawv (thaum muaj feem xyuam) yam tsis tau rov ua dua qhov kev xeem, uas tuaj yeem txo lub sijhawm ua haujlwm ntawm kev lees paub.

1. Xyuas kom muaj kev nyab xeeb ntawm cov khoom

CB daim ntawv pov thawj kuaj xyuas cov khoom siv tsim nyog thiab pom tau tias muaj kev nyab xeeb thaum siv tsis raug. Cov khoom muaj ntawv pov thawj ua pov thawj qhov txaus siab ntawm qhov yuav tsum tau muaj kev nyab xeeb.

▍ Vim li cas MCM?

● Kev Tsim Nyog:MCM yog thawj daim ntawv tso cai CBTL ntawm IEC 62133 tus qauv tsim nyog los ntawm TUV RH hauv Suav teb av loj.

● Daim ntawv pov thawj thiab kev xeem muaj peev xwm:MCM yog thawj thaj chaw ntawm kev sim thiab ntawv pov thawj thib peb rau IEC62133 tus qauv, thiab tau ua tiav ntau tshaj 7000 roj teeb IEC62133 kev sim thiab CB cov ntaub ntawv rau cov neeg siv khoom thoob ntiaj teb.

● Kev pab txhawb nqa:MCM muaj ntau dua 15 tus kws tshaj lij kws tshaj lij tshwj xeeb hauv kev sim raws li IEC 62133 tus qauv. MCM muab cov neeg siv khoom nrog cov lus qhia dav dav, raug, kaw-voj hom kev txhawb nqa thiab cov kev pabcuam cov ntaub ntawv ua ntej.

Ib tug tshiab version ntawmTIAB SA 1642raug tso tawm. Ib qho ntxiv rau qhov kev ntsuam xyuas hnyav yog ntxiv rau lub hnab ntim. Cov kev cai tshwj xeeb yog: Rau lub hnab ntawm tes nrog lub peev xwm ntau dua 300 mAh, yog tias dhau qhov kev ntsuas hnyav tsis dhau, lawv tuaj yeem raug rau Tshooj 14A round pas nrig extrusion test.Pouch cell tsis muaj rooj plaub nyuaj, uas feem ntau ua rau cell rupture, kais tawg, khib nyiab ya tawm thiab lwm yam kev puas tsuaj loj tshwm sim los ntawm tsis ua hauj lwm nyob rau hauv hnyav kev ntsuam xyuas, thiab ua rau nws tsis yooj yim sua kom paub lub internal luv luv Circuit Court tshwm sim los ntawm tus tsim tsis xws luag los yog txheej txheem defect. Nrog rau kev sib tw qws sib tsoo, qhov ua tau tsis zoo hauv lub xov tooj tuaj yeem kuaj pom yam tsis muaj kev puas tsuaj rau cov qauv ntawm tes. Qhov kev hloov kho tau ua nrog qhov xwm txheej no hauv kev txiav txim siab. Muab tus qauv tso rau ntawm qhov chaw tiaj tus. Muab ib puag ncig steel pas nrig nrog txoj kab uas hla ntawm 25 ± 1mm ​​rau saum cov qauv. Lub ntug ntawm tus pas nrig yuav tsum tau ua raws li sab saum toj ntawm lub xovtooj ntawm tes, nrog rau txoj kab ntsug ntsug perpendicular mus rau lub tab (Daim duab 1). Qhov ntev ntawm tus pas nrig yuav tsum yog tsawg kawg yog 5 hli dav dua txhua ntug ntawm cov qauv kuaj. Rau cov hlwb uas muaj qhov zoo thiab qhov tsis zoo ntawm sab nraud, txhua sab ntawm tab yuav tsum tau sim. Txhua sab ntawm tab yuav tsum tau sim ntawm cov qauv sib txawv.Tom qab ntawd nyem lub zog rau ntawm tus pas nrig puag ncig thiab kaw qhov txav mus rau txoj kab ntsug (daim duab 2). Qhov txav ceev ntawm lub phaj nias yuav tsum tsis txhob siab tshaj 0.1mm / s. Thaum lub deformation ntawm tes mus txog 13 ± 1% ntawm lub thickness ntawm lub cell, los yog lub siab mus txog rau lub zog muaj nyob rau hauv Table 1 (cov xov tooj sib txawv thicknesses sib txawv zog qhov tseem ceeb), nres lub phaj displacement thiab tuav nws rau 30s. Qhov kev xeem xaus.
