▍Iyini I-CTIA CERTIFICATION?

I-CTIA, isifinyezo se-Cellular Telecommunications and Internet Association, yinhlangano yomphakathi engenzi nzuzo eyasungulwa ngo-1984 ngenjongo yokuqinisekisa ukuhlomula kwabaqhubi, abakhiqizi nabasebenzisi. I-CTIA iqukethe bonke opharetha base-US nabakhiqizi abavela kumasevisi omsakazo weselula, kanye namasevisi edatha angenantambo nemikhiqizo. Isekelwe yi-FCC (Federal Communications Commission) kanye neCongress, i-CTIA yenza ingxenye enkulu yemisebenzi nemisebenzi eyayisetshenziselwa ukwenziwa uhulumeni. Ngo-1991, i-CTIA yakha uhlelo lokuhlola lomkhiqizo olungachemile, oluzimele nolwendawo eyodwa kanye nesitifiketi somkhakha ongenazintambo. Ngaphansi kwesistimu, yonke imikhiqizo engenantambo esebangeni labathengi izothatha izivivinyo zokuthobela imithetho futhi leyo ethobelana namazinga afanele izovunyelwa ukusebenzisa ukumaka kwe-CTIA nokushayisana kwamashalofu ezitolo emakethe yezokuxhumana yaseNyakatho Melika.

I-CATL (CTIA Authorized Testing Laboratory) imele amalebhu agunyazwe yi-CTIA ukuze ahlolwe futhi abuyekezwe. Imibiko yokuhlola ekhishwe ku-CATL izogunyazwa yonke yi-CTIA. Nakuba eminye imibiko yokuhlola kanye nemiphumela evela ku-non-CATL ngeke ibonwe noma ingakwazi ukufinyelela ku-CTIA. I-CATL egunyazwe yi-CTIA iyahlukahluka ezimbonini nasekutholeni izitifiketi. I-CATL kuphela efanelekela ukuhlolwa nokuhlolwa kokuthobela ibhethri ekwazi ukufinyelela esitifiketini sebhethri ukuze ihambisane ne-IEEE1725.

▍CTIA Amazinga Wokuhlola Ibhethri

a) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobela IEEE1725— Kusebenza Ezinhlelweni Zebhethri ezineseli elilodwa noma amaseli amaningi axhunywe ngokuhambisana;

b) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobelana ne-IEEE1625— Kusebenza Ezinhlelweni Zebhethri ezinamaseli amaningi axhunywe ngokuhambisana noma kokubili ngokuhambisana nochungechunge;

Amathiphu afudumele: Khetha ngenhla kwamazinga wesitifiketi ngokufanelekile kumabhethri asetshenziswa omakhalekhukhwini namakhompyutha. Ungasebenzisi kabi i-IEE1725 kumabhethri kumakhalekhukhwini noma i-IEEE1625 kumabhethri akukhompyutha.

▍Kungani i-MCM?

●Ubuchwepheshe obuqinile:Kusukela ngo-2014, i-MCM ibihambela inkomfa yamaphakethe webhethri ebanjwa yi-CTIA e-US minyaka yonke, futhi iyakwazi ukuthola isibuyekezo sakamuva futhi iqonde amathrendi enqubomgomo emisha mayelana ne-CTIA ngendlela esheshayo, enembayo nesebenzayo.

●Ukufaneleka:I-MCM iyi-CATL egunyazwe yi-CTIA futhi ifaneleka ukwenza zonke izinqubo ezihlobene nesitifiketi okuhlanganisa ukuhlola, ukuhlola kwasefekthri nokulayisha umbiko.

Amabhethri e-Lithium-ion for Power Storage (GB/T 36276-2023) akhishwe ekupheleni kukaDisemba 2023 futhi azosetshenziswa ngoJulayi 1, 2024. Ngokuthuthuka okusheshayo kwemakethe yokugcina amandla ebhethri ye-lithium-ion eminyakeni yamuva, izingozi nazo bezilokhu zenzeka njalo. Ngokusekelwe kulokhu, uma kuqhathaniswa nenguqulo ye-2018, isakhiwo sonke senguqulo entsha sihlala singashintshiwe, kodwa izidingo zobuchwepheshe ziqinile, futhi izidingo zokuhlola ziningi kakhulu.
Isakhiwo se-hierarchical yohlelo lokugcina amandla lumi kanje: amaseli axhunywe ochungechungeni futhi ahambisana ukuze enze imojula yeseli, amamojula amaseli axhunywe ochungechungeni futhi ahambisana ukuze enze iqoqo lamaseli, amaqoqo amaseli axhunywe ngokuhambisana ukuze enze amandla ebhethri. isistimu yokugcina, nezinhlelo zokugcina amandla ebhethri zixhunywe ngokuhambisana ukuze zakhe isiteshi sokugcina amandla ebhethri. Ukusebenza nokuphepha kwesistimu yebhethri kuyisisekelo sokusebenza kwesiteshi sokugcina amandla. I-GB/T 36276-2023 ihlanganisa amapharamitha abalulekile okusebenza nokuphepha kokusebenza kusukela ezingeni lamaseli, amamojula kuya kumaqoqo, futhi icacisa ngokucacile izidingo zeleveli ngayinye yamabhethri.
Ngaso leso sikhathi, i-CPSC iphinde yakhipha umthetho wokugcina ohlukile (88 FR 65296) wokusungula izidingo zokulebula eziyisixwayiso zokupakishwa kwe-inkinobho cells noma amabhethri ohlamvu lwemali (okuhlanganisa amabhethri apakishwe ngokwehlukana nemikhiqizo yabathengi) (kusetshenziswe ngoSepthemba 21, 2024)
