▍Kodi CTIA CERTIFICATION ndi chiyani?

CTIA, chidule cha Cellular Telecommunications and Internet Association, ndi bungwe lopanda phindu lomwe linakhazikitsidwa mu 1984 ndi cholinga chotsimikizira phindu la ogwira ntchito, opanga ndi ogwiritsa ntchito.CTIA ili ndi onse ogwira ntchito ku US ndi opanga kuchokera ku mawayilesi a m'manja, komanso kuchokera ku ma data opanda zingwe ndi zinthu zopangidwa.Mothandizidwa ndi FCC (Federal Communications Commission) ndi Congress, CTIA imachita gawo lalikulu la ntchito ndi ntchito zomwe zidagwiritsidwa ntchito ndi boma.Mu 1991, CTIA idapanga njira yowunikira zinthu mosakondera, yodziyimira payokha komanso yapakati pamakampani opanda zingwe.Pansi pa dongosololi, zinthu zonse zopanda zingwe zomwe zili mugulu la ogula zidzayesa kutsata ndipo omwe akutsatira miyezo yoyenera adzaloledwa kugwiritsa ntchito chizindikiro cha CTIA ndikugundika mashelefu amsika amsika waku North America.

CATL (CTIA Authorized Testing Laboratory) imayimira ma lab ovomerezeka ndi CTIA kuti ayesedwe ndikuwunikanso.Malipoti oyezetsa ochokera ku CATL onse avomerezedwa ndi CTIA.Pomwe malipoti ena oyezetsa ndi zotsatira zochokera kwa omwe si a CATL sizidziwika kapena kukhala ndi mwayi wopeza CTIA.CATL zovomerezeka ndi CTIA zimasiyanasiyana m'mafakitale ndi certification.CATL yokhayo yomwe ili yoyenerera kuyesedwa ndi kuwunika kwa batri yomwe ili ndi mwayi wopeza satifiketi ya batri kuti igwirizane ndi IEEE1725.

▍CTIA Mayesero a Battery

a) Chofunikira Pachiphaso cha Battery System Kutsata IEEE1725- Imagwira Ntchito ku Ma Battery Systems okhala ndi cell imodzi kapena ma cell angapo olumikizidwa mofanana;

b) Chofunikira Pachiphaso cha Battery System Kutsata IEEE1625- Imagwira Ntchito ku Ma Battery Systems okhala ndi ma cell angapo olumikizidwa mofananira kapena mofananira ndi mndandanda;

Malangizo ofunda: Sankhani pamwamba pa ziphaso zotsimikizika zamabatire omwe amagwiritsidwa ntchito m'mafoni am'manja ndi makompyuta.Osagwiritsa ntchito molakwika IEE1725 pamabatire amafoni am'manja kapena IEEE1625 pamabatire apakompyuta.

▍ Chifukwa chiyani MCM?

●Ukadaulo Wolimba:Kuyambira 2014, MCM yakhala ikupezeka pa msonkhano wa batri pack womwe umachitika ndi CTIA ku US chaka chilichonse, ndipo imatha kupeza zosintha zaposachedwa ndikumvetsetsa malingaliro atsopano okhudza CTIA mwachangu, molondola komanso mwachangu.

●Zoyenereza:MCM ndi CATL yovomerezeka ndi CTIA ndipo ndi woyenerera kuchita njira zonse zokhudzana ndi certification kuphatikiza kuyesa, kufufuza fakitale ndi kukweza malipoti.

Mtundu watsopano wa UL 1642 unatulutsidwa.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.  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 lithiamu sekondale ndi mabatire
