Abstract
Exemplary methods and systems related to wireless charging are disclosed. In an exemplary embodiment, a plurality of transmit antennas are used, wherein at least one transmit antenna of the plurality of transmit antennas is configured to be oriented in a different plane than at least one other transmit antenna of the plurality of transmit antennas. Furthermore, each transmit antenna of the plurality of transmit antennas is configured for transmitting power within an associated near-field.
Claims34
A wireless charging system, comprising:
- a first loop antenna having a portion defining a first plane, the first loop antenna being coupled to a first surface that is parallel with the first plane;
- and
- a second loop antenna having a portion defining a second plane, the second loop antenna being coupled to a second surface that is parallel with the second plane, the second plane different than the first plane, and the first and second loop antennas configured to simultaneously wirelessly transmit power at a level sufficient to charge or power a first chargeable device and a second chargeable device based on a combination of power transmitted from the first loop antenna and the second loop antenna;
- and
- a controller configured to determine a total amount of power received by a combination of the first chargeable device and the second chargeable device and to adjust power levels of the first and second loop antennas based on the total amount of power received by the combination of the first chargeable device and the second chargeable device from the first loop antenna and the second loop antenna to increase the total amount of power received by the combination of the first chargeable device and the second chargeable device from the combination of power transmitted from the first loop antenna and the second loop antenna.

A wireless charging system, the system comprising:
- a first means for wirelessly transmitting power to charge a first chargeable device and a second chargeable device, the first transmitting means having a portion defining a first plane and the first transmitting means being coupled to a first surface that is parallel with the first plane;
- a second means for wirelessly transmitting power to charge the first chargeable device and the second chargeable device, the second transmitting means having a portion defining a second plane and the second transmitting means being coupled to a second surface that is parallel with the second plane, the second plane different than the first plane, the first and second transmitting means configured to simultaneously wirelessly transmit power at a level sufficient to charge or power the first chargeable device and the second chargeable device based on a combination of power transmitted from the first and second transmitting means;
- means for determining a total amount of power received by a combination of the first chargeable device and the second chargeable device;
- and
- means for adjusting power levels of the first and second transmitting means based on the total amount of power received by the combination of the first chargeable device and the second chargeable device from the first and second transmitting means to increase the total amount of power received by the combination of the first chargeable device and the second chargeable device from the combination of power transmitted from the first and second transmitting means.
2 more elements
A method for wireless power transfer, comprising:
- simultaneously wirelessly transmitting power via a first loop antenna and a second loop antenna at a level sufficient to charge or power a first chargeable device and a second chargeable device based on a combination of power transmitted from the first loop antenna and the second loop antenna, the first loop antenna having a portion defining a first plane and the first loop antenna being coupled to a first surface that is parallel with the first plane, and the second loop antenna having a portion defining a second plane and the second loop antenna being coupled to a second surface that is parallel with the second plane, the second plane different than the first plane;
- determining a total amount of power received by a combination of the first chargeable device and the second chargeable device;
- and
- adjusting power levels of the first and second loop antennas based on the total amount of power received by the combination of the first chargeable device and the second chargeable device from the first loop antenna and the second loop antenna to increase the total amount of power received by the combination of the first chargeable device and the second chargeable device from the combination of the power transmitted from the first loop antenna and the second loop antenna.
