Upravljanje in vmesniki za WPT - Brezžično polnjenje med napravami (D2DWC) za mobilne naprave z brezžično napajalno močjo modula TX/RX (IEC 63254:2022)
Ta standard opredeljuje specifikacijo in nadzorni protokol modula D2DWC za uporabo funkcij brezžičnega napajanja TX in RX s samo eno napravo. Povezani primeri fizične zasnove antene so predstavljeni v dodatku A za izmenjavo informacij. Ta standard predlaga zahteve za vezje modula D2DWC, sestavljeno iz AP D2DWC, D2DWC IC, antenske enote EMT/WPT in enote PMIC. V 5. poglavju »Specifikacije in nadzorni protokol D2DWC« so opredeljeni podatki o registru in sporočilni protokoli za nadzor WPT, da se izvede funkcija WPT TX. V tem standardu se vmesnik in protokol v procesu brezžičnega napajanja mobilne naprave lahko uporabljata v skladu z ustreznim standardom za brezžični prenos energije. Vsak standard za brezžični prenos energije, ki deluje v frekvenčnem območju 100–350 kHz, je mogoče vključiti na področje uporabe tega standarda. Ta standard je mogoče uporabiti za mobilni brezžični prenos energije v mobilnih telefonih in drugih mobilnih napravah, IoT in industriji mikro-senzorjev ter sorodnih področjih uporabe.
