▍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.

Mtundu watsopano waMtengo wa UL1642anamasulidwa.Njira ina yoyesera zolemetsa imawonjezedwa pama cell athumba.Zofunikira zenizeni ndi izi: Kwa selo la thumba lomwe lili ndi mphamvu zoposa 300 mAh, ngati kuyesedwa kolemera sikunapitirire, akhoza kuyesedwa ndi Gawo 14A kuzungulira ndodo extrusion test.Pouch cell ilibe vuto lolimba, lomwe nthawi zambiri limayambitsa kuphulika kwa ma cell, kuthyoka kwa ma tap, zinyalala zomwe zikuwulukira kunja ndi kuwonongeka kwina kwakukulu komwe kumachitika chifukwa cha kulephera pamayeso amphamvu, ndipo zimapangitsa kuti zikhale zosatheka kuzindikira dera lalifupi lamkati lomwe limayambitsidwa ndi vuto la kapangidwe kake kapena kuwonongeka kwa dongosolo.Ndi kuyesa kozungulira ndodo, zolakwika zomwe zingatheke mu cell zitha kudziwika popanda kuwononga ma cell.Kuwunikiridwaku kudapangidwa poganizira izi. Ikani chitsanzo pamalo athyathyathya.Ikani ndodo yozungulira yachitsulo yokhala ndi mainchesi 25 ± 1mm ​​pamwamba pa chitsanzo.Mphepete mwa ndodo iyenera kugwirizanitsidwa ndi pamwamba pa nsonga ya selo, ndi chigawo chokhazikika cha perpendicular to tabu (FIG. 1).Utali wa ndodoyo uyenera kukhala wosachepera 5mm m'lifupi kuposa m'mphepete mwachitsanzo choyesera.Kwa ma cell okhala ndi ma tabo abwino ndi oyipa mbali zotsutsana, mbali iliyonse ya tabu iyenera kuyesedwa.Mbali iliyonse ya tabu iyenera kuyesedwa pazitsanzo zosiyanasiyana. Kenako kufinya kumagwiritsidwa ntchito pa ndodo yozungulira ndipo kusuntha kwa njira yolunjika kumalembedwa (FIG. 2).Kuthamanga kwa mbale yosindikizira sikuyenera kupitirira 0.1mm / s.Pamene mapindikidwe a selo afika 13 ± 1% ya makulidwe a selo, kapena kupanikizika kumafika pa mphamvu yomwe ikuwonetsedwa mu Table 1 (ma cell makulidwe osiyanasiyana amafanana ndi mphamvu zosiyanasiyana), siyani kusuntha kwa mbale ndikuigwira kwa 30s.Mayeso amatha.
