▍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.

【Zomwe zili mu lingaliroli】
Pa Juni 25, 2021, tsamba lovomerezeka la UL lidatulutsa malingaliro aposachedwa osintha mulingo wa UL2054. Kupempha maganizo kutha mpaka pa July 19, 2021. Zotsatirazi ndi zinthu zisanu ndi chimodzi zosinthidwa mu lingaliro ili:
1. Kuphatikizidwa kwa zofunikira zonse pakupanga mawaya ndi ma terminals: kutsekemera kwa mawaya kuyenera kukwaniritsa zofunikira za UL 758;
2. Zosintha zosiyanasiyana pa muyezo: makamaka kuwongolera molakwika, kusinthidwa kwa miyezo yomwe yatchulidwa;
3. Kuwonjezera pa zofunikira zoyesa zomatira: kupukuta mayeso ndi madzi ndi organic solvents;
4. Kuwonjezeka kwa njira zoyendetsera zigawo ndi mabwalo omwe ali ndi ntchito yotetezera yofanana muyeso yamagetsi: Ngati zigawo ziwiri zofanana kapena mabwalo amagwirira ntchito limodzi kuteteza batri, poganizira cholakwika chimodzi, zigawo ziwiri kapena mabwalo ayenera kulakwitsa. nthawi yomweyo.
5. Kulemba mayeso ocheperako operekera mphamvu ngati mwasankha: ngati kuyesa kwamagetsi kocheperako mu Chaputala 13 cha muyezowo kumatsimikiziridwa molingana ndi zomwe wopanga akufuna. Kusintha kwa chiganizo cha 9.11 - kuyesa kwafupipafupi kwakunja: muyezo woyambirira ndi kugwiritsa ntchito 16AWG (1.3mm2) opanda waya wamkuwa; malingaliro kusinthidwa: kukana kunja kwa dera lalifupi kuyenera kukhala 80 ± 20mΩ waya wopanda mkuwa.
