UL 1642 idawonjezeranso chofunikira choyesa ma cell olimba
Mtengo wa UL1642adawonjezera kufunikira koyeserera kwa ma cell olimba,
Mtengo wa UL1642,
▍Kodi ANATEL Homologation ndi chiyani?
ANATEL ndichidule cha Agencia Nacional de Telecomunicacoes chomwe ndi boma la Brazil kuti lizipereka ziphaso zovomerezeka komanso zodzifunira. Kuvomereza ndi kutsata njira zake ndizofanana pazogulitsa zapakhomo ndi zakunja ku Brazil. Ngati zogulitsa zikugwira ntchito ku chiphaso chokakamiza, zotsatira zoyesa ndi lipoti ziyenera kugwirizana ndi malamulo ndi malamulo omwe ANATEL adafunsa. Satifiketi yamalonda iyenera kuperekedwa ndi ANATEL poyamba zinthu zisanagawidwe pakutsatsa ndikuyikidwa kuti zigwiritsidwe ntchito.
▍Ndani ali ndi udindo pa ANATEL Homologation?
Mabungwe ovomerezeka aboma la Brazil, mabungwe ena ovomerezeka ndi ma lab oyesa ndi ANATEL certification Authority pakuwunika njira yopangira zinthu, monga njira yopangira zinthu, kugula, kupanga, pambuyo pa ntchito ndi zina zotero kuti zitsimikizire kuti chinthucho chikuyenera kutsatiridwa. ndi Brazil standard. Wopanga adzapereka zikalata ndi zitsanzo zoyesa ndikuwunika.
▍Chifukwa chiyani MCM?
● MCM ili ndi zaka 10 zokumana nazo zambiri komanso zothandizira pakuyesa ndi certification: machitidwe apamwamba kwambiri, gulu laukadaulo lodziwa bwino kwambiri, ziphaso zachangu komanso zosavuta komanso zothetsera zoyezetsa.
● MCM imagwira ntchito ndi mabungwe angapo odziwika bwino mdera lanu omwe amapereka mayankho osiyanasiyana, olondola komanso osavuta kwa makasitomala.
Kutsatira kuwonjezereka kwa mwezi watha kwamphamvu kwa cell ya thumba, 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 pazifukwa zina. 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, kuphwanya, kugunda, kugwedezeka, kutentha, kuzungulira kwa kutentha, kutsika, kutsika kwa ndege, kuyaka kwa ndege, ndi kuyeza kwa mpweya wapoizoni.
