▍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.

Mabatire a Lithium-ion for Power Storage (GB/T 36276-2023) adatulutsidwa kumapeto kwa Disembala 2023 ndipo adzagwiritsidwa ntchito pa Julayi 1, 2024. Ndi chitukuko chofulumira cha msika wosungira mphamvu batire wa lithiamu-ion m'zaka zaposachedwa, ngozi nazonso zakhala zikuchitika pafupipafupi. Malingana ndi izi, poyerekeza ndi mtundu wa 2018, mawonekedwe onse a mtundu watsopanowo amakhalabe osasinthika, koma zofunikira zaumisiri zimakhala zovuta kwambiri, ndipo zofunikira zoyesera ndizowonjezereka.
Maonekedwe a hierarchical of the power storage system ali motere: ma cell amalumikizidwa mu mndandanda ndikufanana kuti apange cell module, ma cell module amalumikizidwa mndandanda ndikufanana kuti apange gulu la cell, masango a cell amalumikizidwa mofanana kuti apange mphamvu ya batri. makina osungira, ndi machitidwe osungira mphamvu za batri amalumikizidwa mofanana kuti apange malo osungira mphamvu za batri. Kuchita ndi chitetezo cha batri ndi mwala wapangodya wa ntchito ya malo osungirako mphamvu. GB/T 36276-2023 imakwirira magawo ofunikira ogwirira ntchito ndi chitetezo cha magwiridwe antchito kuchokera pamlingo wa ma cell, ma module mpaka masango, ndikulongosola momveka bwino zofunikira pamlingo uliwonse wa mabatire.
Nthawi yomweyo, CPSC idaperekanso lamulo lomaliza (88 FR 65296) kuti likhazikitse zofunikira zolembera machenjezo pakuyika kwabatani la cells kapena mabatire a ndalama (kuphatikiza mabatire opakidwa mosiyana ndi zinthu zogula) (kukhazikitsidwa pa Seputembara 21, 2024)
