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.

▍ 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.
Tsis ntev los no, Lub Xeev Kev Tswj Xyuas Kev Tswj Xyuas Kev Lag Luam (Standardization Administration) tau pom zoo rau
tso tawm 106 cov qauv tseem ceeb hauv tebchaws, suav nrog thaj chaw ua liaj ua teb & nyob deb nroog, kev tiv thaiv ib puag ncig ntsuab, kev nyab xeeb rau pej xeem, kev kawm deb thiab lwm yam haujlwm. Ntawm lawv, cov qauv ntsig txog cov roj teeb muaj raws li hauv qab no:
Keeb kwm ntawm GB / T 39086-2020: Nrog rau kev loj hlob sai ntawm Kev Lag Luam Tsheb Tshiab Zog, ntau yam
Cov xwm txheej thiab cov xwm txheej zais cia tshwm sim ib ntus xws li tsheb hluav taws xob haus luam yeeb, hluav taws kub, thiab tawg thiab lwm yam.
Ntxiv rau lub roj teeb nws tus kheej ntawm qhov tsis xws luag hauv kev tsim thiab kev tsim khoom. Ib qho kev kawm ntau dua li "lub hlwb" ntawm lub zog hluav taws xob thiab ua ib qho ntawm peb lub thev naus laus zis thev naus laus zis ntawm kev tswj hwm roj teeb (BMS) zoo sib xws. Tsis tas li ntawd, kev tso tawm thiab kev siv lub teb chaws tus qauv tshiab rau EV them nyiaj tau tso tawm cov kev xav tau tshiab rau kev them cov ntaub ntawv sau cov ntaub ntawv raug thiab kev sib txuas lus teb, uas yuav tsum muaj lub roj teeb tswj kev tswj hwm ntawm lub tsheb kom muaj kev sib txuas nrog kev them nyiaj, tswj kev sib koom tes. tswj cov txheej txheem them nqi, thiab xyuas kom muaj kev nyab xeeb ntawm kev them nyiaj. Yog li ntawd, lub teb chaws tus qauv no tau raug tsim.
Cov ntsiab lus tseem ceeb ntawm tus qauv no suav nrog:
1) Qhia ntau yam kev tshaj lij ntawm BMS raws li cov qauv tshiab uas tau tso tawm hauv lub tebchaws, thiab tswj kom muaj qhov sib xws ntawm tus qauv;
2) Qhia meej txog kev sib txuas lus thiab kev sib cuam tshuam kev ua tau zoo ntawm BMS thiab tsheb;
3) Qhia meej txog kev saib xyuas kev ua haujlwm ntawm BMS hauv kev tswj hwm ntawm tes, xws li kub, voltage
sib npaug, SOC, thiab lwm yam;
4) Qhia meej txog kev nyab xeeb hluav taws xob ua haujlwm uas BMS yuav tsum tau ntsib, xws li kev cuam tshuam hluav taws xob siab, rwb thaiv tsev
kev saib xyuas, thiab lwm yam;
5) Qhia qhov chaw ib puag ncig thiab EMC cov yam ntxwv uas BMS yuav tsum ua raws li;
6) Qhia cov txheej txheem xeem raws li cov kev xav tau saum toj no.
Cov qauv rau cov roj teeb lithium rau lub zog tshiab tsheb tau ua tiav lawm; thiab cov qauv rau
them thiab hloov chaw nres tsheb kev tsim kho thiab R & D ntawm cov roj teeb lithium hloov tshiab yog cov kev taw qhia tom ntej ntawm lub zog tshiab. Ntxiv rau cov roj teeb fais fab, BESS siv hauv kev lag luam: xws li chaw nres tsheb hauv xov tooj,
