Abstract

L'invention concerne un procédé et un système de multi-charge sans fil. Le procédé de charge sans fil consiste à sélectionner certains dispositifs mobiles situés dans une zone de charge sous forme d'un groupe, et à fournir aux dispositifs mobiles du groupe sélectionné de l'énergie pour la charge sans fil. Par conséquent, comme la charge du groupe peut se faire, des dispositifs mobiles permettant la charge peuvent être chargés sélectivement sur une base individuelle.
