▍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.

Mtundu watsopano wa UL 1642 unatulutsidwa. Njira ina yoyesera yolemetsa 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 choyima cha perpendicular to tabu (FIG. 1). Utali wa ndodo 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.  Kuyeza makulidwe (kulolera ± 0.1mm) kwa maselo kumayenera kuchitidwa asanayesedwe molingana ndi Zowonjezera A za IEC 61960-3 (Maselo achiwiri ndi mabatire omwe ali ndi alkaline kapena ena omwe si- ma electrolyte acidic - Ma cell achiwiri a lithiamu ndi mabatire - Gawo 3: Ma cell a prismatic ndi cylindrical lithium sekondale ndi mabatire)  Kenako kukanikiza kumayikidwa pa ndodo yozungulira ndipo kusamutsidwa kolunjika 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.  Palibe moto kapena kuphulika kwa zitsanzo.
