Wireless charging and powering of electronic devices in a vehicle
First Claim
1. A method for wireless power transmission, the method comprising:
- scanning, using a wireless communication component of a transmitter, for available receivers within a vehicle that are authorized to receive wirelessly delivered power from the transmitter;
detecting, by the transmitter, a first receiver and a second receiver of the available receivers within the vehicle based on the scanning;
while continuing to scan for available receivers within the vehicle;
receiving, by a connector of the transmitter, where the connector is coupled to a power source of the vehicle, electrical current from the power source that is used by the transmitter to generate a plurality of power waves;
transmitting, by a plurality of antennas of the transmitter, a first set of the plurality of power waves, such that the first set of the plurality of power waves converge to form a first constructive interference pattern in proximity to a location of the first receiver within the vehicle;
receiving, by the wireless communication component of the transmitter, a charging request from the second receiver within the vehicle, wherein the charging request;
(i) corresponds to a request for wirelessly delivered power from the transmitter, and(ii) is sent by the second receiver when a charge level of the second receiver is less than a minimum level of charge; and
adjusting, by a controller of the transmitter, respective gains and phases of at least a second set of the plurality of power waves, andtransmitting the second set of the plurality of power waves such that the second set of the plurality of power waves converge to form a second constructive interference pattern, distinct from the first constructive interference pattern, in proximity to a location of the second receiver within the vehicle.

Abstract
Configurations and methods of wireless power transmission for charging or powering one or more electronic devices inside a vehicle are disclosed. A transmitter capable of single or multiple pocket-forming may be connected to a car lighter, where this transmitter may include a circuitry module and an antenna array integrated within the transmitter, or operatively connected through a cable. This cable may allow the positioning of the antenna array in different locations inside the vehicle suitable for directing RF waves or pockets of energy towards one or more electronic devices. Transmitter'"'"'s configuration can be accessed by one or more electronic devices through Bluetooth communication in order to set up charging or powering priorities.

13. A method for wireless power transmission, the method comprising:
-
scanning, using a wireless communication component of a transmitter, for available receivers within a vehicle that are authorized to receive wirelessly delivered power from the transmitter; detecting, by the transmitter, a first receiver associated with a first electronic device and a second receiver associated with a second electronic device within the vehicle based on the scanning; while continuing to scan for available receivers within the vehicle; receiving, by a connector of the transmitter, where the connector is coupled to a power source of the vehicle, electrical current from the power source that is used by the transmitter to generate a plurality of power waves; receiving, by the wireless communication component of the transmitter, a first wireless charging request sent from the first electronic device within the vehicle, wherein the first wireless charging request; (i) corresponds to a request for wirelessly delivered power from the transmitter, and (ii) is sent by the first electronic device when a charge level of the first electronic device is less than a minimum level of charge; receiving, by the wireless communication component of the transmitter, a second wireless charging request sent from the second electronic device within the vehicle, wherein the second wireless charging request; (i) corresponds to a request for wirelessly delivered power from the transmitter, and (ii) is sent by the second electronic device when a charge level of the second electronic device is less than a minimum level of charge; determining, by a processor of the transmitter, a charging priority associated with each of the first electronic device and the second electronic device based on the first and second wireless charging requests; transmitting, by a plurality of antennas of the transmitter, a first set of the plurality of power waves such that the first set of the plurality of power waves form a first constructive interference pattern in proximity to a location of the first receiver associated with the first electronic device in response to the processor determining that the first electronic device is associated with a higher charging priority than the second electronic device; and transmitting, by the plurality of antennas of the transmitter, a second set of the plurality of power waves such that the second set of the plurality of power waves is phase-shifted and gain-adjusted to form a second constructive interference pattern, distinct from the first constructive interference pattern, in proximity to a location of the second receiver associated with the second electronic device in response to the processor determining that the second electronic device is associated with a higher charging priority than the first electronic device. - View Dependent Claims (14, 15)
