▍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 yovomerezeka ndi CTIA imasiyanasiyana m'mafakitale ndi ma certification. CATL yokhayo yomwe ili yoyenera kuyezetsa kutsata batire ndikuwunika yomwe ili ndi mwayi wopeza satifiketi ya batri kuti igwirizane ndi IEEE1725.

▍CTIA Battery Testing Standards

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.

Kufalikira kwa ma module kumakumana ndi magawo otsatirawa: Kuchulukana kwa kutentha pambuyo pogwiritsa ntchito ma cell matenthedwe, ma cell thermal runaway ndiyeno module thermal runaway. Kuthamanga kwa kutentha kuchokera ku selo limodzi sikukhudza; komabe, pamene kutentha kumafalikira ku maselo ena, kufalitsa kumayambitsa mphamvu ya domino, yomwe imatsogolera kuthawa kwa kutentha kwa gawo lonse, kutulutsa mphamvu zazikulu. Chithunzi 1 chikuwonetsa zotsatira za mayeso othawa kutentha. Gawoli likuyaka moto chifukwa cha kufalitsa kosatsutsika.Kutentha kwa mkati mwa selo kudzakhala kosiyana malinga ndi njira zosiyanasiyana. The coefficient of conductivity kutentha adzakhala apamwamba mu malangizo kufanana ndi mpukutu pachimake cha selo; pomwe mayendedwe omwe ali ofukula ku mpukutuwo amakhala ndi madulidwe otsika. Chifukwa chake kufalikira kwamafuta kuchokera mbali kupita mbali pakati pa ma cell kumakhala mwachangu kuposa momwe zimakhalira kudzera pama tabu kupita ku ma cell. Chifukwa chake kufalitsa kumatha kuwonedwa ngati kufalikira kwa gawo limodzi. Monga ma module a batri amapangidwira kuti azikhala ndi mphamvu zambiri, danga lapakati pa maselo likucheperachepera, zomwe zidzakulitsa kufalikira kwa kutentha. Chifukwa chake, kupondereza kapena kuletsa kufalikira kwa kutentha mu gawoli kudzawonedwa ngati njira yabwino yochepetsera zoopsa.
Titha kuletsa kutha kwa matenthedwe mwachangu kapena mosadukiza.Kupondereza kwamafuta kumagwira makamaka kutengera kasamalidwe ka matenthedwe, monga: 1)Ikani mapaipi ozizira pansi kapena m'mbali zamkati mwa gawo, ndikudzaza ndi madzi ozizira. Kuyenda kwa madzi ozizira kumatha kuchepetsa kufalikira.2)Ikani mipope yozimitsa moto pamwamba pa gawo. Pakakhala kutentha kwamoto, mpweya wotentha kwambiri womwe umatulutsidwa kuchokera ku batri udzayambitsa mipope kuti iwononge zozimitsa kuti zithetsere kufalitsa. Palinso kuthekera kuti kasamalidwe kachitidwe kangathe kugwira ntchito.
