▍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.

Pakalipano, ngozi zambiri zachitetezo cha mabatire a lithiamu-ion zimachitika chifukwa cha kulephera kwa dera lachitetezo, zomwe zimapangitsa kuti batire yotenthetsera kuthawa ndipo imayambitsa moto ndi kuphulika. Chifukwa chake, kuti muzindikire kugwiritsa ntchito motetezeka kwa batire ya lithiamu, kapangidwe kake kachitetezo ndikofunikira kwambiri, ndipo mitundu yonse ya zinthu zomwe zimayambitsa kulephera kwa batire ya lithiamu ziyenera kuganiziridwa. Kuphatikiza pa kupanga, zolephera zimayamba chifukwa cha kusintha kwa zinthu zakunja, monga kuchulukitsa, kutulutsa kwambiri komanso kutentha kwambiri. Ngati magawowa akuyang'aniridwa mu nthawi yeniyeni ndipo njira zodzitetezera zidzatengedwa zikasintha, zochitika za kuthawa kwa kutentha zingathe kupewedwa. Kukonzekera kwa chitetezo cha batri ya lithiamu kumaphatikizapo zinthu zingapo: kusankha kwa maselo, mapangidwe apangidwe ndi mapangidwe a chitetezo cha BMS. Chifukwa cha mankhwala osiyanasiyana, chitetezo chimasiyanasiyana muzinthu zosiyanasiyana za cathode za batri ya lithiamu. Mwachitsanzo, lithiamu iron phosphate imakhala ngati olivine, yomwe imakhala yokhazikika komanso yosavuta kugwa. Lithium cobaltate ndi lithiamu ternary, komabe, ndizomwe zimakhala zosavuta kugwa. Kusankhidwa kwa olekanitsa ndikofunikanso kwambiri, chifukwa ntchito yake ikugwirizana mwachindunji ndi chitetezo cha selo. Chifukwa chake pakusankhidwa kwa ma cell, osati malipoti ozindikira okha komanso momwe wopanga amapangira, zida ndi magawo ake ziyenera kuganiziridwa. Insulation pakati pa selo ndi mpanda; Kusungunula pakati pa mitengo yamtengo ndi mpanda; PCB magetsi katayanitsidwe ndi creepage mtunda, mawaya mamangidwe mkati, grounding kapangidwe, etc.
