Udaba lweI-UL 1642inguqulo entsha ebuyekeziwe - Ukuhlolwa komthelela omkhulu esikhundleni seseli yesikhwama,
I-UL 1642,

▍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.

Inguqulo entsha yeI-UL 1642wakhululwa. Okunye ukuhlolwa komthelela osindayo kwengezwa kumaseli esikhwama. Izidingo eziqondile yilezi: Kuseli lesikhwama elinomthamo omkhulu kuno-300 mAh, uma kuphumelele ukuhlolwa komthelela osindayo kungazange kuphasiswe, angafakwa ngaphansi kokuhlolwa kwe-extrusion yenduku eyindilinga yeSigaba 14A.Iseli yesikhwama ayinalo ikesi eliqinile, okuvame ukuholela ukuphuka kweseli, ukuphuka kwethepha, udoti endizela ngaphandle kanye nomunye umonakalo omkhulu odalwe ukwehluleka esivivinyweni somthelela osindayo, futhi kwenza kungenzeki ukuhlonza isifunda esifushane sangaphakathi esibangelwe iphutha ledizayini noma iphutha lenqubo. Ngokuhlolwa kwe-round rod crush, amaphutha okungenzeka kuseli angatholwa ngaphandle kokulimaza isakhiwo seseli. Isibuyekezo senziwe ngalesi simo ngokucatshangelwa.Beka isampula endaweni eyisicaba. Beka induku yensimbi eyindilinga enobubanzi obungu-25±1mm ngaphezulu kwesampula. Unqenqema lwenduku kufanele luqondaniswe nonqenqema olungaphezulu lweseli, ne-eksisi eqondile i-perpendicular kuthebhu (FIG. 1). Ubude benduku kufanele okungenani bube ububanzi obungu-5mm kunomkhawulo ngamunye wesampula yokuhlola. Kumaseli anamathebhu amahle noma anegethivu ezinhlangothini ezibhekene, uhlangothi ngalunye lwethebhu ludinga ukuhlolwa. Uhlangothi ngalunye lwethebhu kufanele luhlolwe kumasampula ahlukene.Isilinganiso sogqinsi (ukubekezelela ±0.1mm) samaseli kuzokwenziwa ngaphambi kokuhlolwa ngokuhambisana neSithasiselo A se-IEC 61960-3 (Amaseli esibili namabhethri aqukethe i-alkaline noma okunye okungewona- Ama-electrolyte ane-acidic - Amaseli e-lithium yesibili ephathekayo namabhethri - Ingxenye 3: Amaseli wesibili we-lithium we-Prismatic kanye ne-cylindrical kanye namabhethri)
