▍Kodi CB Certification ndi chiyani?

IECEE CB ndiye njira yoyamba yapadziko lonse lapansi yovomerezera malipoti oyesa chitetezo cha zida zamagetsi.NCB (National Certification Body) ifika pa mgwirizano wamayiko osiyanasiyana, womwe umathandizira opanga kuti apeze ziphaso zadziko kuchokera kumayiko ena omwe ali mamembala pansi pa dongosolo la CB potengera kusamutsa chimodzi mwa ziphaso za NCB.

Satifiketi ya CB ndi chikalata chovomerezeka cha CB choperekedwa ndi NCB yovomerezeka, chomwe ndikudziwitsa NCB ina kuti zitsanzo zomwe zayesedwa zikugwirizana ndi zomwe zikufunika.

Monga mtundu wa lipoti lokhazikika, lipoti la CB limalemba zofunikira kuchokera ku IEC wamba ndi chinthu.Lipoti la CB silimangopereka zotsatira za mayeso onse ofunikira, kuyeza, kutsimikizira, kuyang'anira ndi kuwunika momveka bwino komanso mosadziwika bwino, komanso kuphatikiza zithunzi, chithunzi chozungulira, zithunzi ndi malongosoledwe azinthu.Malinga ndi lamulo la CB scheme, lipoti la CB siligwira ntchito mpaka litapereka satifiketi ya CB palimodzi.

▍Nchifukwa chiyani timafunikira CB Certification?

1. Chindunjilykuzindikirazedi or kuvomerezaedmwamembalamayiko

Ndi satifiketi ya CB ndi lipoti la mayeso a CB, malonda anu amatha kutumizidwa kumayiko ena mwachindunji.

1. Sinthani kumayiko ena ziphaso

Satifiketi ya CB imatha kusinthidwa mwachindunji kukhala satifiketi ya mayiko omwe ali mamembala ake, popereka satifiketi ya CB, lipoti la mayeso ndi lipoti loyesa kusiyana (ngati kuli koyenera) osabwereza mayeso, omwe angafupikitse nthawi yotsogolera yotsimikizira.

1. Onetsetsani Chitetezo cha Zamalonda

Mayeso a certification a CB amawona kugwiritsidwa ntchito moyenera kwa chinthucho komanso chitetezo chodziwikiratu chikagwiritsidwa ntchito molakwika.Chitsimikizo chotsimikizika chimatsimikizira zokhutiritsa zofunikira zachitetezo.

▍Chifukwa chiyani MCM?

● Ziyeneretso:MCM ndiye CBTL yoyamba yovomerezeka ya IEC 62133 yovomerezeka ndi TUV RH ku China.

● Chitsimikizo ndi kuthekera koyesa:MCM ili m'gulu loyamba loyesa ndi kutsimikizira chipani chachitatu pa muyezo wa IEC62133, ndipo yamaliza kuyesa kwa batri 7000 IEC62133 ndi malipoti a CB kwa makasitomala apadziko lonse lapansi.

● Thandizo laukadaulo:MCM ili ndi akatswiri opitilira 15 odziwika bwino pakuyesa malinga ndi muyezo wa IEC 62133.MCM imapatsa makasitomala chithandizo chokwanira, cholondola, chotsekeka chaukadaulo komanso zidziwitso zotsogola.

Chitetezo cha njira yosungiramo mphamvu ndizovuta kwambiri.Monga chimodzi mwazinthu zofunika kwambiri zosungira mphamvu zamagetsi, chitetezo cha batri la lithiamu-ion ndikofunikira kwambiri.Monga kuyesa kwamphamvu kwa kutentha kumatha kuwunika mwachindunji kuopsa kwa moto wopezeka m'makina osungiramo mphamvu, mayiko ambiri apanga njira zoyeserera zofananira pamiyezo yawo kuti awone chiwopsezo cha kuthawa kwamafuta.Mwachitsanzo, IEC 62619 yoperekedwa ndi International Electrotechnical Commission (IEC) imafotokoza njira yofalitsira kuti iwunikire chikoka cha kuthawa kwa cell;Chinese national standard GB/T 36276 amafuna matenthedwe akuthawa kuwunika kwa selo ndi matenthedwe kuthawa mayeso a batire gawo;US Underwriters Laboratories (UL) imasindikiza miyezo iwiri, UL 1973 ndi UL 9540A, zonse zomwe zimayesa kuthawa kwa kutentha.UL 9540A idapangidwa mwapadera kuti iwunike kuchokera pamiyezo inayi: cell, module, cabinet, ndi kufalitsa kutentha pamlingo woika.Zotsatira za mayeso othamangitsidwa ndi kutentha sizingangoyang'ana chitetezo chonse cha batri, komanso kutilola kuti timvetsetse msanga kuthawa kwa maselo, ndikupereka magawo ofanana ndi mapangidwe a chitetezo cha maselo omwe ali ndi chemistry yofanana.Gulu lotsatira la kuyesa kwazomwe mukuthawa ndi kuti mumvetsetse mawonekedwe a kuthawa kwamafuta pagawo lililonse ndi zida zomwe zili muselo.Panthawiyi, kutentha kwa selo ndi 0 ℃ / min (0 ~ T1), selo lokha silimawotcha, ndipo palibe mankhwala omwe ali mkati.Stage 2 ndi kuwonongeka kwa SEI.Ndi kuwonjezeka kwa kutentha, filimu ya SEI imayamba kusungunuka ikafika pafupifupi 90 ℃ (T1).Panthawiyi, selo lidzakhala ndi kutulutsa kutentha pang'ono, ndipo zikhoza kuwoneka kuchokera ku Chithunzi 1 (B) kuti kutentha kwa kutentha kumasinthasintha.Kutentha kukafika 110 ℃, electrolyte ndi electrode negative, komanso electrolyte palokha zidzachitika angapo kuwola anachita, kubala kuchuluka kwa mpweya.Mpweya womwe umatulutsa mosalekeza umapangitsa kuti kukakamiza mkati mwa selo kuchuluke kwambiri, kufika pamtengo wopumira, ndipo makina otulutsa mpweya amatseguka (T2).Panthawi imeneyi, mpweya wambiri, electrolytes ndi zinthu zina zimatulutsidwa, zomwe zimachotsa kutentha, ndipo kutentha kumawonjezeka kumakhala koipa.
