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

▍ 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.

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 tuaj tos qee qhov tseem ceeb Q&A rau koj qhov kev siv.Qhov kev hloov ntawm daim ntawv lo yuav tsum yog ib qho teeb meem uas 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, rated peev 4500mAh. Lub zog ntsuas sib npaug 3.7V * 4.5Ah = 16.65Wh.
Lub zog ntsuas tau tso cai sau npe li 16.65Wh, 16.7Wh lossis 17Wh.
