UL 1642 idawonjezeranso chofunikira choyesa ma cell olimba
Mtengo wa UL1642adawonjezera kufunikira koyeserera kwa ma cell olimba,
Mtengo wa UL1642,
▍Sitifiketi ya SIRIM
Pofuna chitetezo cha anthu ndi katundu, boma la Malaysia limakhazikitsa dongosolo la certification lazinthu ndikuyika zowunikira pazida zamagetsi, zambiri & ma multimedia ndi zida zomangira. Zogulitsa zoyendetsedwa zitha kutumizidwa ku Malaysia pokhapokha mutalandira satifiketi yotsimikizira zazinthu ndikuzilemba.
▍SIRIM QAS
SIRIM QAS, kampani yothandizirana ndi Malaysian Institute of Industry Standards, ndi gawo lokhalo losankhidwa la mabungwe olamulira dziko la Malaysia (KDPNHEP, SKMM, etc.).
Satifiketi yachiwiri ya batire imasankhidwa ndi KDPNHEP (Ministry of Domestic Trade and Consumer Affairs ya ku Malaysia) kuti ndiyo yokhayo yopereka ziphaso. Pakadali pano, opanga, ogulitsa kunja ndi amalonda atha kulembetsa ziphaso ku SIRIM QAS ndikufunsira kuyesa ndi kutsimikizira mabatire achiwiri pansi pa chiphaso chovomerezeka.
▍Sitifiketi ya SIRIM- Battery Yachiwiri
Batire lachiwiri pano liyenera kupatsidwa satifiketi mwakufuna kwake koma likhala likuvomerezedwa posachedwa. Tsiku lenileni lovomerezeka limadalira nthawi yolengezetsa yaku Malaysian. SIRIM QAS yayamba kale kuvomereza zopempha za certification.
Chitsimikizo cha batri yachiwiri: MS IEC 62133:2017 kapena IEC 62133:2012
▍Chifukwa chiyani MCM?
● Anakhazikitsa njira yabwino yosinthira luso ndi njira yosinthira zidziwitso ndi SIRIM QAS yomwe idapatsa katswiri kuti azigwira ntchito ndi mapulojekiti a MCM ndi mafunso okha ndikugawana zambiri zaposachedwa kwambiri za derali.
● SIRIM QAS imazindikira data yoyeserera ya MCM kuti zitsanzo ziyesedwe mu MCM m'malo motumiza ku Malaysia.
● Kupereka chithandizo chamtundu umodzi wotsimikizira za mabatire, ma adapter ndi mafoni aku Malaysia.
Kutsatira kuonjezedwa kwa mwezi watha kwamphamvu kwa cell cell, mwezi unoMtengo wa UL1642akufuna kuwonjezera chiyeso chofunikira cha maselo olimba a lithiamu.Pakali pano, mabatire ambiri olimba amachokera ku mabatire a lithiamu-sulfure. 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 zoyeserera zapadera ndi: kuyeza kwa mphamvu, kufupikitsa, kuchuluka kwachilendo, kutulutsa mokakamiza, kugwedezeka, kugunda, kugunda, kugwedezeka, kutentha, kuzungulira kwa kutentha, kutsika kwapansi, ndege yoyaka moto, ndi kuyeza kwa mpweya wapoizoni.
Muyezo wa GB/T 35590, womwe umakhudza gwero lamagetsi osunthika, sunaphatikizidwe 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.
