IsingenisokweI-CTIA

I-Cellular Telecommunications Industry Association (CTIA) inohlelo lwesitifiketi olumboza amaseli, amabhethri, ama-adaptha nabasingathi kanye neminye imikhiqizo esetshenziswa emikhiqizweni yokuxhumana engenantambo (njengamaselula, amakhompyutha aphathekayo). Phakathi kwazo, isitifiketi se-CTIA samaseli siqinile kakhulu. Ngaphandle kokuhlolwa kokusebenza kokuphepha okuvamile, i-CTIA iphinde igxile ekwakhiweni kwesakhiwo samaseli, izinqubo ezibalulekile zenqubo yokukhiqiza nokulawula ikhwalithi yayo. Nakuba isitifiketi se-CTIA singaphoqelekile, opharetha bezokuxhumana abakhulu eNyakatho Melika badinga ukuthi imikhiqizo yabahlinzeki babo iphumelele isitifiketi se-CTIA, ngakho-ke isitifiketi se-CTIA singabhekwa njengemfuneko yokungena emakethe yezokuxhumana yaseNyakatho Melika.

Isendlalelo Senkomfa

Izinga lesitifiketi se-CTIA belilokhu libhekise ku-IEEE 1725 kanye ne-IEEE 1625 eshicilelwe yi-IEEE (Institute of Electrical and Electronics Engineers). Ngaphambilini, i-IEEE 1725 yayisetshenziswa kumabhethri ngaphandle kwesakhiwo sochungechunge; kuyilapho i-IEEE 1625 isetshenziswa kumabhethri anokuxhumana okubili noma ngaphezulu kochungechunge. Njengoba uhlelo lwesitifiketi sebhethri le-CTIA belusebenzisa i-IEEE 1725 njengezinga lokubhekisela, ngemva kokukhishwa kwenguqulo entsha ye-IEEE 1725-2021 ngo-2021, i-CTIA iphinde yakhe iqembu elisebenzayo ukuze liqale uhlelo lokubuyekeza uhlelo lwesitifiketi se-CTIA.

Iqembu elisebenzayo lacela kakhulu imibono kumalabhorethri, abakhiqizi bamabhethri, abakhiqizi bamaselula, abakhiqizi abasingatha ama-adaptha, njll. NgoMeyi walo nyaka, umhlangano wokuqala wohlaka lwe-CRD (Umbhalo Wezimfuneko Zokugunyazwa) wabanjelwa. Phakathi naleso sikhathi, kwamiswa iqembu le-adaptha elikhethekile ukuze lixoxe ngesixhumi esibonakalayo se-USB nezinye izindaba ngokwehlukana. Ngemva kwesikhathi esingaphezu kwesigamu sonyaka, umhlangano wokugcina wenziwa kule nyanga. Iqinisekisa ukuthi uhlelo olusha lwesitifiketi lwe-CTIA IEEE 1725 (CRD) luzokhishwa ngoZibandlela, kanye nesikhathi soshintsho esiyizinyanga eziyisithupha. Lokhu kusho ukuthi ukuqinisekiswa kwe-CTIA kufanele kwenziwe kusetshenziswa inguqulo entsha yombhalo we-CRD ngemva kukaJuni 2023. Thina, i-MCM, njengelungu Le-CTIA's Test Laboratory (CATL), kanye ne-CTIA's Battery Working Group, siphakamise izibuyekezo zohlelo olusha lokuhlola futhi sahlanganyela. kuzo zonke izingxoxo ze-CTIA IEEE1725-2021 CRD. Okulandelayo yizibuyekezo ezibalulekile:

Ukubuyekezwa Okuyinhloko

1. Izimfuneko zesistimu engaphansi yebhethri/yephakethe yengeziwe, imikhiqizo idinga ukuhlangabezana nejwayelekile noma i-UL 2054 noma i-UL 62133-2 noma i-IEC 62133-2 (enokuchezuka kwase-US). Kuyaqapheleka ukuthi ngaphambili asikho isidingo sokuhlinzeka nganoma yimiphi imibhalo yephakethe.
2. Ukuze kuhlolwe iseli, i-IEEE 1725-2021 isuse ukuhlolwa kwesiyingi esifushane seseli ngemva kwemijikelezo yokushisa engu-25 ephezulu nephansi. Nakuba i-CTIA ibihlale ikhuluma ngezinga le-IEEE, ekugcineni inqume ukugcina lolu hlolo. Lokhu okokucabangela ukuthi izimo zokuhlola zinzima, kodwa kwamanye amabhethri amadala, amabi, ukuhlola okunjalo kungathola ukusebenza kwempahla ngokushesha. Iphinde ibonise ukuzimisela kwe-CTIA ukulawula ngokuqinile ukuphepha kwamaseli.
3. I-CRD entsha ye-CTIA IEEE 1725 isusa izinto zokuhlola ezihlobene zohlobo B lwe-USB futhi iphinde iguqule umkhawulo wokuhlola wokugcwala ngokweqile kwamadivayisi abamba usuka ku-9V ukuya ku-24V ukuze athobelane nokucaciswa kohlobo C lwe-USB. Lokhu kuphinda kubonise ukuthi ngemva kokuphela kwenkathi yoshintsho ngonyaka ozayo, ama-adaptha ohlobo lwe-USB lwe-USB ngeke esakwazi ukufaka isicelo sokuthola isitifiketi se-CTIA. Lokhu kuphinde kubhekelele umkhakha, manje osewushintsha kakhulu ama-adaptha ohlobo lwe-USB kuya kuma-adaptha ohlobo C lwe-USB.
4. Ububanzi bokusebenza bomkhiqizo we-1725 bunwetshiwe. Ngokukhula komthamo webhethri leselula, umthamo webhethri yeselula eyodwa ngeke usakwazi ukuhlangabezana nokusetshenziswa isikhathi eside komakhalekhukhwini. Ngakho-ke, isitifiketi sokuthobela i-IEEE 1725 sokuthola isitifiketi sebhethri leselula siphinde sandise ububanzi bokucushwa kweselula ebhethrini.

• Iseli elilodwa (1S1P)
• Amaseli ahambisanayo amaningi (1S nP)
• 2 uchungechunge lwamaseli amaningi ahambisanayo (2S nP)

Konke okungenhla kungagunyazwa ngaphansi kwe-CTIA IEEE 1725, futhi okunye ukulungiselelwa kwebhethri kufanele kuhlangabezane nezimfuneko ze-CTIA IEEE 1625.

Isifinyezo

Uma kuqhathaniswa nenguqulo yakudala, entsha ayishintshi kakhulu ezintweni zokuhlola, kodwa inguqulo entsha ibeka phambili inani lezimfuneko ezintsha zesitifiketi, icacisa ububanzi besitifiketi somkhiqizo, njll. Futhi isahluko se-adaptha sashintshwa kakhulu. Injongo yesitifiketi se-adaptha iwukuqinisekisa izinhlobo zokubonwa ezisetshenziswa kakhulu, futhi Uhlobo C lwe-USB luhambisana kakhulu nezinhlelo zokusebenza ezijwayelekile. Ngokusekelwe kulokhu, i-CTIA isebenzisa i-USB Type C njengokuphela kohlobo lwe-adaptha. Okwamanje i-EU kanye ne-South Korea banokusalungiswa kokuhlanganisa isixhumi esibonakalayo se-USB, isinqumo i-CTIA eyasithatha sokushiya Uhlobo B lwe-USB futhi iye Ohlotsheni C lwe-USB futhi sibeka isisekelo sokusebenzisana kwe-USB okungenzeka kube okuhlangene eNyakatho Melika esikhathini esizayo.

Ukwengeza, ukuphawula okungenhla kanye nezibuyekezo kungukuqukethwe okuvunyelwene ngakho emhlanganweni, imithetho yokugcina kufanele ibhekisele ezingeni elisemthethweni. Njengamanje uhlelo olusha lwaleli zinga alukakhishwa kanti kulindeleke ukuthi lukhishwe maphakathi no-December.
