Cov Ntawv Pov Thawj thiab Cov Ntawv Pov Thawj
Cov qauv xeem: GB31241-2014:Lithium ion hlwb thiab cov roj teeb siv hauv cov khoom siv hluav taws xob portable - Cov kev xav tau ntawm kev nyab xeeb
Daim ntawv pov thawj: CQC11-464112-2015:Secondary Battery and Battery Pack Safety Certification Rules for Portable Electronic Devices
Keeb Kwm thiab Hnub Ua Haujlwm
1. GB31241-2014 tau luam tawm rau lub Kaum Ob Hlis 5th, 2014;
2. GB31241-2014 tau raug coj los siv rau lub Yim Hli 1st, 2015.;
3. Thaum Lub Kaum Hli 15th, 2015, Certification and Accreditation Administration tau tshaj tawm ib qho kev daws teeb meem ntawm cov qauv xeem ntxiv GB31241 rau cov khoom tseem ceeb "roj teeb" ntawm cov khoom siv suab thiab video, cov khoom siv thev naus laus zis thiab cov khoom siv hauv xov tooj. Qhov kev daws teeb meem tau teev tseg tias cov roj teeb lithium siv rau hauv cov khoom saum toj no yuav tsum tau sim sim raws li GB31241-2014, lossis tau txais daim ntawv pov thawj cais.
Nco tseg: GB 31241-2014 yog tus qauv tsim nyog hauv tebchaws. Tag nrho cov khoom siv roj teeb lithium muag hauv Suav teb yuav tsum ua raws li tus qauv GB31241. Cov qauv no yuav raug siv rau hauv cov qauv qauv tshiab rau kev soj ntsuam hauv tebchaws, xeev thiab hauv zos.
▍ Scope of Certification
GB31241-2014Lithium ion hlwb thiab cov roj teeb siv hauv cov khoom siv hluav taws xob portable - Cov kev xav tau ntawm kev nyab xeeb
Cov ntaub ntawv pov thawjFeem ntau yog rau cov khoom siv hluav taws xob hauv xov tooj ntawm tes uas tau teem sijhawm tsawg dua 18kg thiab tuaj yeem nqa tau los ntawm cov neeg siv feem ntau. Cov piv txwv tseem ceeb yog raws li hauv qab no. Cov khoom siv hluav taws xob portable uas tau teev tseg hauv qab no tsis suav nrog txhua yam khoom, yog li cov khoom lag luam tsis tau teev tseg tsis tas yuav nyob sab nraud ntawm tus qauv no.
Cov cuab yeej siv tau: Cov roj teeb lithium-ion thiab cov roj teeb uas siv rau hauv cov khoom siv yuav tsum tau ua raws li cov qauv kev cai.
| Electronic khoom qeb | Cov qauv nthuav dav ntawm ntau hom khoom siv hluav taws xob |

▍ Vim li cas MCM?
● Kev lees paub Kev Tsim Nyog: MCM yog CQC qhov chaw kuaj pom muaj ntawv pov thawj thiab CESI kuaj pom zoo. Daim ntawv tshaj tawm xeem tuaj yeem thov ncaj qha rau CQC lossis CESI daim ntawv pov thawj;
● Kev pab txhawb nqa: MCM muaj ntau yam khoom siv kuaj GB31241 thiab tau nruab nrog ntau tshaj 10 tus kws tshaj lij los ua qhov kev tshawb fawb tob txog kev sim tshuab, ntawv pov thawj, kev kuaj xyuas lub Hoobkas thiab lwm cov txheej txheem, uas tuaj yeem muab tau ntau dua thiab kho tau raws li GB 31241 daim ntawv pov thawj cov kev pabcuam thoob ntiaj teb. cov neeg siv khoom.
Cov txheej txheem xeem zoo ib yam ntawm IEC 61960-3: 2017, IEC 62620: 2014 thiab JIS C 8715-1: 2018. Cov kev sib txawv tseem ceeb yog raws li nram no: Kev ntsuas kub sib txawv. IEC 62620: 2014 thiab JIS C 8715-1: 2018 tswj qhov kub ntawm 5 ℃ siab dua li IEC 61960-3: 2017. Qhov ntsuas kub qis dua yuav ua rau nws muaj viscosity ntawm electrolyte, uas yuav ua rau qis zog ntawm ions. Yog li cov tshuaj tiv thaiv yuav qeeb qeeb, thiab Ohm tsis kam thiab polarization kuj yuav loj dua, uas yuav ua rau muaj qhov sib txawv ntawm DCIR nce.SoC txawv. Cov SoC xav tau hauv IEC 62620: 2014 thiab JIS C 8715-1: 2018 yog 50% ± 10%, thaum IEC 61960-3: 2017 yog 100%. Cov xwm txheej ntawm kev them nqi muaj feem cuam tshuam rau DCIR. Feem ntau DCIR cov txiaj ntsig kev xeem yuav tau qis dua nrog nce ntawm SoC. Qhov no muaj feem xyuam rau cov txheej txheem ntawm cov tshuaj tiv thaiv. Nyob rau hauv qis SoC, tus nqi hloov pauv tsis kam Rct yuav siab dua; thiab Rct yuav txo qis nrog nce ntawm SoC, yog li DCIR.Lub sij hawm tso tawm txawv. IEC 62620: 2014 thiab JIS C 8715-1: 2018 yuav tsum muaj lub sijhawm tso tawm ntev dua li IEC 61960-3: 2017. Lub sijhawm ntev mem tes yuav ua rau qis dua ntawm DCIR, thiab nthuav tawm qhov sib txawv ntawm linearity. Yog vim li cas yog tias qhov nce ntawm lub sijhawm mem tes yuav ua rau Rct siab dua thiab ua tau zoo.Txawm hais tias JIS C 8715-1: 2018 hais txog IEC 62620: 2014, lawv muaj cov ntsiab lus sib txawv ntawm cov roj teeb siab. IEC 62620: 2014 txhais tau tias cov roj teeb muaj peev xwm tuaj yeem tso tawm tsis pub tsawg dua 7.0C ntawm tam sim no. Thaum JIS C 8715-1: 2018 txhais cov roj teeb siab siab yog cov tuaj yeem tawm nrog 3.5C.
