▍ ANATEL Homologation yog dab tsi?

ANATEL yog luv luv rau Agencia Nacional de Telecomunicacoes uas yog Brazil tsoomfwv txoj cai tswjfwm kev sib txuas lus cov khoom lag luam rau ob qho tib si yuav tsum tau lees paub thiab yeem daim ntawv pov thawj. Nws cov kev pom zoo thiab kev ua raws cai yog tib yam rau Brazil cov khoom siv hauv tsev thiab txawv teb chaws. Yog tias cov khoom muaj feem xyuam rau cov ntawv pov thawj uas yuav tsum tau ua, cov ntawv xeem thiab daim ntawv tshaj tawm yuav tsum ua raws li cov cai thiab cov cai uas tau thov los ntawm ANATEL. Daim ntawv pov thawj khoom yuav tsum tau tso cai los ntawm ANATEL ua ntej cov khoom lag luam nthuav tawm hauv kev lag luam thiab muab tso rau hauv daim ntawv thov.

▍ Leej twg yog tus lav rau ANATEL Homologation?

Lub koom haum Brazilian tsoomfwv tus qauv, lwm lub koom haum lees paub thiab cov chaw kuaj sim yog ANATEL daim ntawv pov thawj txoj cai rau kev tshuaj xyuas cov txheej txheem tsim khoom, xws li cov txheej txheem tsim khoom, kev yuav khoom, txheej txheem tsim khoom, tom qab kev pabcuam thiab lwm yam txhawm rau txheeb xyuas cov khoom siv lub cev kom ua raws. nrog Brazil tus qauv. Tus neeg tsim khoom yuav tsum muab cov ntaub ntawv thiab cov qauv rau kev sim thiab ntsuas.

▍ Vim li cas MCM?

● MCM muaj 10 xyoo kev paub dhau los thiab cov peev txheej hauv kev sim thiab ntawv pov thawj kev lag luam: cov kev pabcuam zoo, pab pawg ua haujlwm tau zoo, ceev thiab yooj yim daim ntawv pov thawj thiab cov kev daws teeb meem.

● MCM koom tes nrog ntau lub koom haum zoo hauv zos uas tau lees paub los muab ntau yam kev daws teeb meem, kev pabcuam raug thiab yooj yim rau cov neeg siv khoom.

Ib qho tshiab ntawm UL 1642 tau 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 raug kuaj ntawm cov qauv sib txawv.Kev ntsuas qhov tuab (kev ua siab ntev ± 0.1mm) rau cov hlwb yuav tsum tau ua ua ntej kev sim ua raws li Daim Ntawv Ntxiv A ntawm IEC 61960-3 (Cov hlwb thib ob thiab cov roj teeb uas muaj alkaline lossis lwm yam tsis yog- acidic electrolytes - Portable Secondary lithium cells thiab roj teeb - Ntu 3: Prismatic thiab cylindrical lithium ob lub hlwb thiab cov roj teeb) Tom qab nyem nyem nyem rau ntawm tus pas nrig puag ncig thiab qhov txav mus rau txoj kab ntsug tau sau tseg (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. Tsis muaj hluav taws kub lossis tawg ntawm cov qauv.
