▍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?
- Chindunjilykuzindikirazedi or kuvomerezaedmwamembalamayiko
Ndi satifiketi ya CB ndi lipoti la mayeso a CB, malonda anu amatha kutumizidwa kumayiko ena mwachindunji.
- 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.
- 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.
Kutsatira kuwonjezera mwezi watha wa zimakhudza kwambiri thumba selo, mwezi uno UL 1642 akufuna kuwonjezera chiyeso chofunika boma olimba lithiamu maselo.Batire ya Lithium-sulfure ili ndi mphamvu zapadera (1672mAh/g) ndi kachulukidwe kamphamvu (2600Wh/kg), komwe ndi kuwirikiza ka 5 kuposa batire yachikhalidwe ya lithiamu-ion.Chifukwa chake, batire yolimba ndi imodzi mwamalo otentha kwambiri a batri ya lithiamu.Komabe, kusintha kwakukulu kwa kuchuluka kwa sulfure cathode panthawi ya delithium / lithiamu, vuto la dendrite la lithiamu anode komanso kusowa kwa madulidwe a electrolyte olimba kwalepheretsa malonda a sulfure cathode.Chifukwa chake kwa zaka zambiri, ofufuza akhala akuyesetsa kukonza ma electrolyte ndi mawonekedwe a batri yolimba.UL 1642 imawonjezera malingalirowa ndi cholinga chothana ndi zovuta zomwe zimayambitsidwa ndi mawonekedwe a batri olimba (ndi cell) ndi zoopsa zomwe zingachitike zikagwiritsidwa ntchito.Kupatula apo, maselo okhala ndi ma electrolyte a sulfide amatha kutulutsa mpweya wapoizoni ngati hydrogen sulfide pansi pamikhalidwe yovuta kwambiri.Choncho, kuwonjezera pa mayesero ena achizolowezi, tiyeneranso kuyeza kuchuluka kwa mpweya wapoizoni pambuyo poyesa.Zinthu zoyezetsa zina ndi monga: kuyeza kwa mphamvu, kuzungulira kwachidule, kuchuluka kwachilendo, kutulutsa mokakamiza, kugwedezeka, kuphwanya, kugunda, kugwedezeka, kutentha, kusinthasintha kwa kutentha, kutsika kwapansi, ndege yoyaka, ndi kuyeza kwa mpweya wapoizoni. The standard GB/T 35590, yomwe chimakwirira gwero lamphamvu lamagetsi, sichiphatikizidwe mu chiphaso cha 3C.Chifukwa chachikulu chingakhale chakuti GB/T 35590 imayang'ana kwambiri ntchito ya gwero lamphamvu lamagetsi m'malo mwa chitetezo, ndipo zofunikira zachitetezo zimatchulidwa kwambiri ku GB 4943.1.Ngakhale chiphaso cha 3C ndichokhudza kuwonetsetsa chitetezo chazinthu, chifukwa chake GB 4943.1 imasankhidwa ngati mulingo wotsimikizira pamagwero amagetsi osunthika.
