Abstract

L'invention porte sur un système de transmission d'énergie électrique sans fil comprenant une extrémité émettrice (21) et une extrémité réceptrice (22). L'extrémité réceptrice (22) est pourvue d'un interrupteur physique (224) utilisé pour commander l'alimentation électrique d'un circuit de commande (223) de l'extrémité réceptrice (22). Le circuit de commande (223) émet un signal d'activation à un module récepteur sans fil (212) de l'extrémité émettrice (21) par l'intermédiaire d'un module émetteur sans fil (222). Sur la base du signal d'activation, l'extrémité émettrice (21) se réveille pour passer dans un état de travail. Le système de transmission d'énergie électrique sans fil, l'extrémité réceptrice, l'extrémité émettrice et le procédé de réveil pour le système permettent le réveil d'une extrémité émettrice dissimulée et d'une extrémité émettrice embarquée pour la mise en œuvre d'une transmission d'énergie électrique, tout en réduisant en même temps des problèmes de sécurité causés par une fausse manœuvre de l'utilisateur, et sont fortement automatisés.
