Abstract

A wireless energy transfer enabled battery includes a resonator that is positioned asymmetrically in a battery sized enclosure such that when two wirelessly enabled batteries are placed in close proximity the resonators of the two batteries have low coupling.

Claims

1. An assembly of at least two resonator coils comprising:

a first resonator coil configured for wireless energy transfer via oscillating magnetic fields; and

a second resonator coil configured for wireless energy transfer via oscillating magnetic fields,

wherein the assembly is configured such that (i) the first resonator coil is positioned in close proximity to the second resonator coil, and (ii) the first resonator coil is oriented with respect to the second resonator coil in a configuration to achieve weak coupling.
