Q&A rauGB 31241-2022Kev xeem thiab ntawv pov thawj,
GB 31241-2022,

▍ 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.

Raws li GB 31241-2022 tau tshaj tawm, CCC daim ntawv pov thawj tuaj yeem pib thov txij lub Yim Hli 1st 2023. Muaj kev hloov pauv ib xyoos, uas txhais tau hais tias txij lub Yim Hli 1st 2024, tag nrho cov roj teeb lithium-ion tsis tuaj yeem nkag mus rau hauv Suav lag luam yam tsis muaj CCC daim ntawv pov thawj. Qee cov tuam ntxhab tab tom npaj rau GB 31241-2022 kuaj thiab ntawv pov thawj. Raws li muaj ntau yam kev hloov pauv tsis yog ntawm kev xeem cov ntsiab lus xwb, tab sis kuj yuav tsum muaj ntawm cov ntawv sau thiab cov ntaub ntawv thov, MCM tau txais ntau qhov kev nug txheeb ze. Peb khaws qee qhov tseem ceeb Q&A rau koj qhov kev siv.Qhov kev hloov ntawm daim ntawv lo yuav tsum yog ib qho ntawm cov teeb meem tsom ntsoov rau. Piv nrog rau xyoo 2014 version, tus tshiab ntxiv tias cov ntawv roj teeb yuav tsum tau cim nrog lub zog ntsuas hluav taws xob, ntsuas hluav taws xob, lub Hoobkas tsim khoom thiab hnub tsim khoom (lossis ntau tus naj npawb).Qhov laj thawj tseem ceeb ntawm kev kos lub zog yog vim UN 38.3, nyob rau hauv uas lub zog ntsuas. yuav raug txiav txim siab rau kev nyab xeeb kev thauj mus los. Feem ntau lub zog yog xam los ntawm qhov ntsuas voltage * rated peev. Koj tuaj yeem kos raws li qhov xwm txheej tiag tiag, lossis hloov tus lej. Tab sis nws tsis raug tso cai los ntsuas tus lej. Nws yog vim hais tias nyob rau hauv cov kev cai ntawm kev thauj mus los, cov khoom raug categorized rau hauv txawv theem txaus ntshai los ntawm lub zog, xws li 20Wh thiab 100Wh. Yog tias lub zog daim duab sib npaug, nws yuav ua rau muaj kev phom sij. Piv txwv li Rated voltage: 3.7V, ntsuas peev 4500mAh. Lub zog ntsuas sib npaug sib npaug 3.7V * 4.5Ah = 16.65Wh.Lub zog ntsuas tau tso cai rau daim ntawv lo raws li 16.65Wh, 16.7Wh lossis 17Wh.
Ntxiv hnub tsim khoom yog rau traceability thaum cov khoom nkag mus rau hauv kev ua lag luam. Raws li cov roj teeb lithium-ion yog qhov yuav tsum tau ua rau CCC daim ntawv pov thawj, yuav muaj kev soj ntsuam kev lag luam rau cov khoom no. Thaum muaj cov khoom tsis tsim nyog, lawv yuav tsum tau rov qab. Hnub tsim khoom tuaj yeem pab txhawm rau taug qab ntau qhov kev koom tes. Yog tias cov chaw tsim khoom tsis kos hnub tsim khoom, lossis kos qhov muag tsis pom kev, yuav muaj kev pheej hmoo tias tag nrho koj cov khoom yuav tsum rov qab los.
Tsis muaj tus qauv qhia rau hnub tim. Koj tuaj yeem kos rau xyoo / hli / hnub, lossis xyoo / hli, lossis tsuas yog kos tus lej ntau. Tab sis nyob rau hauv cov spec yuav tsum muaj ib qho kev piav qhia txog cov lej ntau, thiab cov lej ntawd yuav tsum muaj cov ntaub ntawv ntawm hnub tsim khoom. Thov nco ntsoov yog tias koj kos nrog ntau tus lej, ces yuav tsum tsis txhob rov ua dua hauv 10 xyoo.
