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 |
| 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. |

▍ 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.
Lub 2017 version ntawm lub teb chaws tus txheej txheem Technical Standard rau roj teeb tswj System ntawm Electrochemical Energy Storage Station (GB/T 34131-2017) tau raug kho dua, thiab 2023 version ntawm lub teb chaws tus qauv roj teeb Management System rau hluav taws xob txuag hluav taws xob (GB/T 34131-2023) tau raug tso tawm tsis ntev los no thiab yuav raug coj los siv rau lub Kaum Hlis 1 xyoo no. GB / T 34131 tshiab feem ntau muaj cov kev hloov pauv hauv qab no:
Cov ntaub ntawv tau txais kev ua yuam kev ntau yam thiab lub sijhawm ua piv txwv ntawm tam sim no, qhov hluav taws xob thiab qhov kub thiab txias tau nruj dua;
Cov kev cai thiab kev sim kev sib txuas lus, kev tswj xyuas, kev tiv thaiv kev tiv thaiv kev tiv thaiv, kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob, kev kub siab thiab qis, kev tiv thaiv ntsev- huab cua, hluav taws xob adaptability, electromagnetic compatibility thiab lwm yam ntxiv;
Qhov chaw ua haujlwm kub ntawm BMS yog hloov kho ntawm 0 ~ 45 ℃ to -20 ~ 65 ℃. Qhov siab tshaj plaws tso cai yuam kev ntawm SOE yog hloov kho los ntawm 8% mus rau 5%. Lub sijhawm nruab nrab tsis muaj teeb meem ua haujlwm raug hloov kho los ntawm tsis pub tsawg tshaj 40000h mus rau tsis pub tsawg tshaj 20000h, thiab lub neej ua haujlwm tsis pub tsawg tshaj 10 xyoo;
Cov kev xav tau ntawm cov qauv ntsuas tau raug ntxiv.
Cov kev hloov pauv no yuav ua rau muaj kev hloov pauv tseem ceeb rau BMS cov cuab yeej tsim khoom, tsim qauv engineering, tshuaj xyuas, kev ua haujlwm thiab kev saib xyuas. Cov tuam txhab lag luam tseem ceeb kuj yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus ntawm tus qauv tshiab raws sij hawm thiab npaj ua ntej.
