NhanganyayayeCTIA

Iyo Cellular Telecommunications Industry Association (CTIA) ine certification scheme inovhara maseru, mabhatiri, adapta uye mahosti uye zvimwe zvigadzirwa zvinoshandiswa mumagetsi ekukurukurirana zvigadzirwa (senge mbozhanhare, malaptop). Pakati pavo, CTIA certification yemasero inonyanya kuomarara. Kunze kwekuyedzwa kwekuita kwekuchengetedza kwakawanda, CTIA inotarisawo pane dhizaini yemaseru, iwo akakosha maitiro ekugadzira uye kutonga kwayo kwemhando. Kunyangwe chitupa cheCTIA chisiri chekusungirwa, vakuru venharembozha muNorth America vanoda kuti zvigadzirwa zvevatengesi vavo vapfuure chitupa cheCTIA, saka chitupa cheCTIA chinogona zvakare kutariswa sechinhu chinodiwa chekupinda kumusika wekuNorth America wekutaurirana.

Conference Background

CTIA's certification standard yakagara ichireva IEEE 1725 uye IEEE 1625 yakaburitswa neIEEE (Institute of Electrical and Electronics Engineers). Kare, IEEE 1725 yaishandiswa kumabhatiri asina nhevedzano chimiro; nepo IEEE 1625 ichishandiswa kumabhatiri ane maviri kana anopfuura akatevedzana ekubatanidza. Sezvo CTIA bhatiri setifiketi chirongwa yanga ichishandisa IEEE 1725 seyereferensi chiyero, mushure mekuburitswa kweshanduro nyowani yeIEEE 1725-2021 muna 2021, CTIA yakaumbawo boka rinoshanda kuti ritange chirongwa chekuvandudza CTIA certification scheme.

Boka rinoshanda rakakumbira zvikuru pfungwa kubva kumarabhoritari, vanogadzira mabhatiri, vanogadzira nharembozha, vagadziri vevagadziri, vanogadzira adapta, nezvimwewo. Muna Chivabvu gore rino, musangano wekutanga weCRD (Certification Requirements Document) wakaitwa. Munguva iyi, boka rakasarudzika rakagadzirwa kuti rikurukure USB interface uye dzimwe nyaya zvakasiyana. Pashure peinopfuura hafu yegore, musangano wokupedzisira wakaitwa mwedzi uno. Inosimbisa kuti chirongwa chitsva chetifiketi cheCTIA IEEE 1725 (CRD) chichapihwa muna Zvita, paine nguva yekuchinja yemwedzi mitanhatu. Izvi zvinoreva kuti certification yeCTIA inofanira kuitwa pachishandiswa vhezheni itsva yegwaro reCRD mushure meChikumi 2023. Isu, MCM, senhengo yeCTIA's Test Laboratory (CATL), uye CTIA's Battery Working Group, takaronga kudzokorora chirongwa chitsva chebvunzo uye takatora chikamu. mukati meCTIA IEEE1725-2021 CRD nhaurirano. Izvi zvinotevera zvidzoreso zvakakosha:

Main Revisions

1. Zvinodiwa zvebhatiri / pack subsystem yakawedzerwa, zvigadzirwa zvinoda kusangana neyakajairwa UL 2054 kana UL 62133-2 kana IEC 62133-2 (ine US kutsauka). Zvakakosha kucherechedza kuti kare hapana chikonzero chekupa chero magwaro epakiti.
2. Yeyedzo yesero, IEEE 1725-2021 yakadzima iyo pfupi-yedunhu bvunzo yesero mushure memakumi maviri neshanu epamusoro uye yakaderera tembiricha. Kunyangwe CTIA yagara ichitaura kune iyo IEEE chiyero, yakazofunga kuchengetedza iyi bvunzo. Uku kufunga kuti mamiriro ebvunzo akanyanya kuomarara, asi kune kumwe kuchembera, mabhatiri akashata, bvunzo yakadai inogona kuona kuita kwechinhu nekukurumidza. Inoratidzawo kutsunga kweCTIA kunyatso kudzora kuchengetedzwa kwemasero.
3. Iyo itsva CRD yeCTIA IEEE 1725 inobvisa zvine chekuita nemiyedzo zvinhu zve USB Type B uye zvakare inoshandura muganho wekuedzwa we overvoltage yezvishandiso zvinotambira kubva pa9V kuenda ku24V kuti ienderane neiyo USB Type C yakatarwa. Izvi zvakare zvinoratidza kuti kana nguva yekushandura yapera gore rinouya, maadapter e USB Type B haachakwanisa kunyorera chitupa cheCTIA. Izvi zvinobatawo indasitiri, iyo yave kunyanya kushandura USB Type B adapter kune USB Type C adapter.
4. Iyo chiyero chekushandisa che1725 chigadzirwa chakawedzerwa. Nekuwedzera kwebhatiri renharembozha, huwandu hwebhatiri-sero hahuchakwanise kusangana nekushandiswa kwenguva refu kweserura. Naizvozvo, IEEE 1725 yekutevedzera chitupa chenharembozha bhatiri chitupa inowedzerawo huwandu hwesero masisitimu mubhatiri.

• Sero rimwechete (1S1P)
• Multiple parallel cells (1S nP)
• 2 akatevedzana akawanda-anoenderana maseru (2S nP)

Zvese zviri pamusoro zvinogona kusimbiswa pasi peCTIA IEEE 1725, uye mamwe magadzirirwo ebhatiri anofanirwa kuita zvinodiwa neCTIA IEEE 1625.

Summary

Zvichienzaniswa neshanduro yekare, itsva haishanduki zvakanyanya muzvinhu zvekuedzwa, asi shanduro itsva inoisa mberi nhamba yezvitupa zvitsva zvinodiwa, kujekesa chiyero chechigadzirwa chechigadzirwa, nezvimwewo. Uye chitsauko cheadapter chakagadziridzwa zvakanyanya. Chinangwa chechitupa cheadapta ndechekuona mhando dzemashandisirwo anonyanya kushandiswa, uye USB Type C inonyanya kuenderana nemashandisirwo makuru. Zvichienderana neizvi, CTIA inoshandisa USB Type C seyo yega adapta mhando. Parizvino EU neSouth Korea dzine gwaro rekubatanidza USB interface, danho rakatorwa neCTIA rekusiya USB Type B uye kuenda kuUSB Type C inoisawo hwaro hwekugona kubatana USB interface muNorth America mune ramangwana.

Pamusoro pezvo, zvataurwa pamusoro apa uye kudzokorora ndizvo izvo zvakabvumiranwa pamusangano, iyo yekupedzisira mirau inofanirwa kutaura kune yakarongeka mwero. Parizvino vhezheni iyi itsva haisati yaburitswa uye inotarisirwa kuburitswa pakati paZvita.
