Title (EN) WIRELESS ELECTRIC POWER TRANSFER
(FR) TRANSFERT D'ÉNERGIE SANS FIL
Abstract:
(EN) Methods and systems for wireless transmission of power to a battery-operated device include a power receiving apparatus featuring at least one receiving resonator and a housing dimensioned to engage with a battery compartment of a battery-operated device, and a power transmitting apparatus including: a first pair of spaced source resonators, where each source resonator in the first pair features a loop of conducting material surrounding a common first axis; a second pair of spaced source resonators, where each source resonator in the second pair features a loop of conducting material surrounding a common second axis different from the first axis; and a controller coupled to the first and second pairs of source resonators and configured to provide non-radiative wireless power transfer from the power transmitting apparatus to the power receiving apparatus by alternately activating the first and second pairs of source resonators.
(FR) L'invention concerne des procédés et des systèmes destinés à la transmission d'énergie sans fil à un dispositif alimenté par batterie, qui impliquent un appareil récepteur d'énergie comprenant au moins un résonateur de réception et un logement conçu pour entrer en prise avec le compartiment de la batterie d'un dispositif alimenté par batterie, ainsi qu'un appareil transmetteur d'énergie comportant : une première paire de résonateurs sources espacés, chaque résonateur source de cette première paire étant doté d'une boucle de matériau conducteur qui entoure un premier axe commun; une seconde paire de résonateurs sources espacés, chaque résonateur source de cette seconde paire étant muni d'une boucle de matériau conducteur qui entoure un second axe commun différent du premier; et un régulateur couplé à la première et à la seconde paire de résonateurs sources et servant à assurer un transfert d'énergie sans fil non radiatif au départ de l'appareil transmetteur d'énergie et à destination de l'appareil récepteur d'énergie, grâce à l'activation en alternance de la première et de la seconde paire de résonateurs sources.
