▍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 okuhambisanayo 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.

I-YD/T 2344.1-2023 “Iphakethe lebhethri le-lithium iron phosphate yokuxhumana Ingxenye 1: Iphakethe lebhethri elihlanganisiwe” likhishwe ekupheleni kukaDisemba 2023 futhi selisetshenziswe ngo-April 1, 2024. Ngokuthuthukiswa kobuchwepheshe obuhlanganisiwe bebhethri ye-lithium iron phosphate , kunemikhiqizo ehlanganisiwe yebhethri ye-lithium iron phosphate ehlanganisiwe, futhi izimo zokusetshenziswa kwazo ziya ngokuya ziba zibanzi. Izinga lomthamo alikhawulelwe ku-100Ah nangaphansi. Manje sekunemikhiqizo engu-150 Ah kanye ne-200 Ah. Izindinganiso zangempela ngeke zisakwazi ukumboza imikhiqizo enjalo. Ngakho-ke, inguqulo entsha yezinga le-YD/T 2344.1-2023 libuyekeze izidingo zamagama, ibhethri nezindlela zokuhlola iphakethe lebhethri.
Kulokhu umhleli uzokulethela ukuqhathaniswa kwezinguquko ezibalulekile phakathi kwamazinga amadala namasha e-YD/T 2344.1
Okusha:
Lo mbhalo usebenza kuphakethe elihlanganisiwe lebhethri le-lithium iron phosphate elisetshenziswa kusistimu yokuphakela amandla engu-48V DC (eyakhiwa amabhethri angu-16 3.2V axhunywe ochungechungeni, kamuva olubizwa ngokuthi iphakethe lebhethri).
Uma inombolo yochungechunge loxhumano ingu-15 noma ezinye izimo, ungabheka isimo sangempela.
