Abstract

La présente invention concerne une norme qui définit l'interface pour le transfert d'énergie électrique sans fil vers de multiples dispositifs (y compris un dispositif) qui nécessitent une charge au sein de quelques mètres. Afin de fournir une WPT pour de multiples dispositifs, des fonctionnalités, une structure de système, des primitives, un format de trame, et des procédures sont définis. Cette norme utilise sélectivement diverses largeurs de bande de fréquence qui varient de la basse fréquence de 50 kHz à la haute fréquence de 15 MHz pour le transfert d'énergie électrique sans fil. Pour la commande de système, des supports de la signalisation par laquelle des données et des signaux de commande peuvent être échangés sont nécessaires. Cette norme peut être appliquée au domaine industriel multimédia pour l'utilisation de batteries telles que des bornes mobiles, des ordinateurs portables, des lecteurs multimédia portables, etc.
