▍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.

Pa November 27, 2023, "Buku la UN la Mayesero ndi Zofunikira" (Chiv. 8) linatulutsidwa mwalamulo pa webusaiti ya United States. "Buku la UN la Mayesero ndi Zofunikira" (Chiv. 8) likuvomereza zosinthidwa zomwe zinapangidwa ndi gawo la 11 la United Nations TDG ndi GHS Expert Committee pa "UN Manual of Tests and Criteria" (Chiv. 7) ndi Kusintha kwake 1 . Monga kuyesa kofunikira kwa kayendetsedwe ka chitetezo cha batri, "Buku la UN la Mayesero ndi Zofunikira" (Chiv. 8) yawonjezera gawo latsopano la 38.3.3.2 "Kuyesedwa kwa maselo a sodium ion ndi mabatire", ndipo panthawi imodzimodziyo anawonjezera zolemba zokhazokha zokhudzana ndi . mabatire a sodium-ion mu UN "Recommendation on Transport of Dangerous Goods" (TDG) Rev. 23: UN 3551 ndi UN 3522.
T.1: Kuyerekeza kokwera (selo ndi batri)
Maselo oyesera ndi mabatire adzasungidwa pa kuthamanga kwa 11.6 kPa kapena kuchepera kwa maola asanu ndi limodzi pa kutentha kozungulira (20 ± 5 ℃)
Maselo oyesera ndi mabatire ayenera kusungidwa kwa maola osachepera asanu ndi limodzi pa kutentha kofanana ndi 72 ℃ ndi -40 ℃. Njirayi iyenera kubwerezedwa mpaka magawo 10 onse atha.
Maselo ndi mabatire amatetezedwa mwamphamvu ku nsanja ya makina ogwedezeka, ndi kugwedezeka kwake kukhala mawonekedwe a sinusoidal ndi kusesa kwa logarithmic pakati pa 7 Hz ndi 200 Hz, ndi matalikidwe a 0.8mm, kwa selo ndi batire yaying'ono imanyamula mathamangitsidwe apamwamba kwambiri. 8 gn, ndi batire lalikulu paketi mathamangitsidwe pazipita 2 gn.
