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 kuaj xyuas lub tebchaws, lub 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 |
| Portable cov khoom siv hauv chaw ua haujlwm | phau ntawv, pda, thiab lwm yam. |
| Cov khoom siv sib txuas lus txawb | xov tooj ntawm tes, xov tooj cordless, Bluetooth headset, walkie-talkie, thiab lwm yam. |
| Portable audio thiab video khoom | portable TV teeb, portable player, lub koob yees duab, yees duab yees, thiab lwm yam. |
| Lwm yam khoom siv portable | electronic navigator, digital photo frame, game consoles, e-books, thiab lwm yam. |
▍ 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.
Kev ntsuam xyuas quab yuam tawm yog ib yam khoom rau kev kuaj kev nyab xeeb ntawm kev tawm. Feem ntau cov xovtooj ntawm tes yuav raug tso tawm hauv 1 ItA rau 90 min. Daim duab 1 yog ib daim ntawv qhia txog kev tawm dag zog los ntawm ib hom lithium-ion roj teeb ntawm tes. Tsis zoo li cov qauv zoo tagnrho (raws li qhia hauv daim duab 2), qhov voltage thiab tam sim no hloov pauv. Yog li ntawd, peb sim ntsuas tus thawj xibfwb tom qab daim ntawv qhia.
Raws li qhov sib txawv ntawm qhov voltage, peb tuaj yeem cais cov txheej txheem tawm mus rau peb theem. Hauv thawj theem, qhov hluav taws xob poob qis ntawm 3V txog 0.65V. Hauv theem ob, qhov hluav taws xob nyob ib puag ncig 0.65V txog 0.5V. Qhov voltage nres poob, thiab muaj kev hloov pauv. Hauv theem thib peb, qhov hluav taws xob poob rau 0V, thiab tsis muaj qhov hloov pauv. Ntawm no qhov voltage hais txog qhov sib txawv ntawm anode thiab cathode.
Voltage txo nrog kev tso tawm tas li. Qhov no yog vim lub peev xwm ntawm cov ncej tsis zoo mus siab dua thiab cov ncej zoo tau qis dua, thiab li-ion khiav tawm ntawm tus ncej tsis zoo mus rau tus ncej zoo. Raws li qhov kev sim siv 1C tam sim no, qhov hluav taws xob poob sai sai. SEI zaj duab xis tej zaum yuav tawg nyob rau hauv cov txheej txheem no, tsim roj thiab cua sov.
Qhov tsis zoo ntawm tus ncej muaj peev xwm nce mus txog qhov muaj peev xwm tshaj plaws uas yuav ua rau cov ntawv ci tooj liab yaj. Raws li muaj cov pa roj carbon coated, yuav tsum muaj peev xwm ntau dua los ua rau cov ntawv ci tooj liab yaj, vim cu-ion hloov hluav taws xob. Hauv qhov tsis zoo, cov ntawv ci tooj liab yog yaj thiab oxidized rau Cu + thiab tom qab ntawd Cu2 + thiab cov cu-ion nkag mus los ntawm cov yeeb yaj kiab sib cais mus rau tus ncej zoo, nrog Cu2 + redox rau Cu +, thiab tom qab ntawd redox rau tooj liab, tso rau ntawm tus ncej zoo.
