IntshayeleloyeI-CTIA

I-Cellular Telecommunications Industry Association (CTIA) ineskimu sesiqinisekiso esigubungela iiseli, iibhetri, iiadaptha kunye neenginginya kunye nezinye iimveliso ezisetyenziswa kwiimveliso zonxibelelwano ezingenazingcingo (ezifana neeselfowuni, iilaptops). Phakathi kwazo, isiqinisekiso se-CTIA seeseli singqongqo. Ngaphandle kovavanyo lwentsebenzo yokhuseleko jikelele, i-CTIA ikwagxininisa kuyilo lwesakhiwo seeseli, iinkqubo eziphambili zenkqubo yokuvelisa kunye nolawulo lomgangatho wayo. Nangona isatifikethi se-CTIA singesosinyanzelo, abaqhubi abakhulu be-telecom eMntla Melika bafuna iimveliso zababoneleli babo ukuba baphumelele isatifikethi se-CTIA, ngoko ke isatifikethi se-CTIA sinokuqwalaselwa njengemfuneko yokungena kwimakethi yonxibelelwano yaseMntla Melika.

Imvelaphi yeNkomfa

Umgangatho wesatifikethi se-CTIA ubusoloko ubhekisa kwi-IEEE 1725 kunye ne-IEEE 1625 epapashwe yi-IEEE (Iziko leeNjineli zoMbane kunye nezoMbane). Ngaphambili, i-IEEE 1725 isetyenziswe kwiibhetri ngaphandle koluhlu lwesakhiwo; ngelixa i-IEEE 1625 isetyenziswa kwiibhetri ezinonxibelelwano ezimbini nangaphezulu. Njengoko inkqubo yesatifikethi sebhetri ye-CTIA ibisoloko isebenzisa i-IEEE 1725 njengomgangatho wesalathiso, emva kokukhutshwa koguqulelo olutsha lwe-IEEE 1725-2021 ngo-2021, i-CTIA ikwayile iqela elisebenzayo lokuqalisa inkqubo yokuhlaziya iskimu sesiqinisekiso se-CTIA.

Iqela elisebenzayo lacela kakhulu izimvo kwiilabhoratri, abavelisi beebhetri, abavelisi beeselfowuni, abavelisi abakhoyo, abavelisi beeadaptha, njl.njl. NgoMeyi walo nyaka, intlanganiso yokuqala yoyilo lweCRD (uXwebhu lweeMfuno zeSiqinisekiso) yabanjwa. Ngeli xesha, iqela elikhethekileyo leadaptha lasekwa ukuba lixoxe nge-interface ye-USB kunye neminye imiba ngokwahlukeneyo. Emva kwesiqingatha sonyaka, isemina yokugqibela yabanjwa kule nyanga. Iqinisekisa ukuba isicwangciso esitsha sesatifikethi se-CTIA IEEE 1725 (CRD) siya kukhutshwa ngoDisemba, kunye nexesha lotshintsho leenyanga ezintandathu. Oku kuthetha ukuba isatifikethi seCTIA kufuneka senziwe kusetyenziswa inguqulelo entsha yoxwebhu lweCRD emva kukaJuni 2023. Thina, MCM, njengelungu leCTIA's Test Laboratory (CATL), kunye neCTIA's Battery Working Group, uhlaziyo olucetywayo kwisicwangciso esitsha sovavanyo saza sathatha inxaxheba. kuzo zonke iingxoxo ze-CTIA IEEE1725-2021 CRD. Olu lulandelayo luhlaziyo olubalulekileyo:

Uhlaziyo oluphambili

1. Iimfuno zebhetri/isixokelelwano sepakethe yongezwa, iimveliso kufuneka zihlangabezane nemigangatho nokuba yi-UL 2054 okanye UL 62133-2 okanye i-IEC 62133-2 (ngokutenxa e-US). Kuyaphawuleka ukuba ngaphambili akukho mfuneko yokubonelela ngawo nawaphi na amaxwebhu epakethi.
2. Kuvavanyo lweseli, i-IEEE 1725-2021 icime uvavanyo olufutshane lwesekethe yeseli emva kwe-25 ephezulu kunye nemijikelo yobushushu obuphantsi. Nangona i-CTIA isoloko ibhekisa kumgangatho we-IEEE, ekugqibeleni yagqiba ekubeni ilugcine olu vavanyo. Oku kukuqwalasela ukuba iimeko zovavanyo zinzima, kodwa ngenxa yokuguga, iibhetri ezimbi, uvavanyo olunjalo lunokubona ukusebenza kwezinto ngokukhawuleza. Ikwabonisa ukuzimisela kwe-CTIA ukulawula ngokungqongqo ukhuseleko lweeseli.
3. I-CRD entsha ye-CTIA IEEE 1725 isusa izinto zovavanyo ezinxulumene nohlobo lwe-B ye-USB kwaye iphinde itshintshe umda wovavanyo lokugqithiswa kwezixhobo zokusingathwa ukusuka kwi-9V ukuya kwi-24V ukuhambelana neenkcukacha ze-USB Type C. Oku kukwabonisa ukuba emva kokuphela kwexesha lotshintsho kunyaka ozayo, iiadaptha ze-USB Type B azisayi kuphinda zikwazi ukufaka isicelo sesatifikethi se-CTIA. Oku kukwabonelela kushishino, ngoku olutshintsha kakhulu iadaptha zohlobo lwe-USB kwiiadaptha zohlobo C lwe-USB.
4. Umda wesicelo se-1725 imveliso yandisiwe. Ngokunyuka komthamo webhetri yeselfowuni, umthamo webhetri yeseli enye awunakukwazi ukuhlangabezana nokusetyenziswa kwexesha elide leselfowuni. Ke ngoko, isatifikethi sokuthotyelwa kwe-IEEE 1725 sesatifikethi sebhetri yeselfowuni sikwandisa uluhlu lweeselfowuni kwibhetri.

• Iseli enye (1S1P)
• Iiseli ezininzi ezinxuseneyo (1S nP)
• Iiseli ezi-2 ezihambelanayo ezininzi (2S nP)

Konke oku ngasentla kunokuqinisekiswa phantsi kwe-CTIA IEEE 1725, kunye nolunye ulungelelwaniso lwebhetri kufuneka luhlangabezane neemfuno ze-CTIA IEEE 1625.

Isishwankathelo

Xa kuthelekiswa noguqulelo oludala, entsha ayitshintshi kakhulu kwizinto zokuvavanya, kodwa inguqulelo entsha ibeka phambili inani leemfuno zesatifikethi esitsha, icacisa ububanzi besatifikethi semveliso, njl njl. Kwaye i-adapter isahluko yatshintshwa kakhulu. Injongo yesatifikethi se-adaptha kukuqinisekisa ezona ntlobo zixhaphakileyo zojongano olusetyenziswayo, kwaye i-USB Type C ihambelana kakhulu nezicelo eziphambili. Ngokusekwe koku, i-CTIA isebenzisa Uhlobo C lwe-USB njengolona hlobo lweadaptha kuphela. Okwangoku i-EU kunye ne-South Korea zinoyilo lokudibanisa ujongano lwe-USB, isigqibo se-CTIA esenziwe ukulahla i-USB Type B kwaye sifudukele kwi-USB Type C sikwabeka isiseko se-interface enokwenzeka edibeneyo ye-USB eMntla Melika kwixesha elizayo.

Ukongezelela, ezi zimvo zingasentla kunye nohlaziyo zingumxholo ekuvunyelwene ngawo kwintlanganiso, imimiselo yokugqibela kufuneka ibhekiselele kumgangatho osemthethweni. Okwangoku inguqulelo entsha yalo mgangatho ayikakhutshwa kwaye kulindeleke ukuba ikhutshwe phakathi kuDisemba.
