Abstract
An apparatus and method for transmission of wireless power to a plurality of chargeable devices. The apparatus and method include and provide for a wireless power transmitter including a power transmitting element configured to use a current at a first level to wirelessly transmit power sufficient to provide power to one or more chargeable devices positioned within a charging region. The apparatus and method further include and provide for a controller to detect a subsequent chargeable device positioned within the charging region and to adjust the current from the first level to a default level prior to communication with the subsequent chargeable device.
Claims30
A device for wireless power transfer, the device comprising:
- a power transmitting element configured to use a current at a first level to wirelessly transmit power sufficient to provide power to one or more chargeable devices positioned within a charging region;
- and
- a controller operationally coupled to the power transmitting element and configured to:
- detect a subsequent chargeable device positioned within the charging region;
- and
- adjust the current from the first level to a default level prior to communication with the subsequent chargeable device.
A method for wireless power transfer comprising:
- wirelessly transmitting power from a power transmitting element, using a current at a first level, sufficient to provide power to one or more chargeable devices positioned within a charging region of the power transmitting element;
- detecting a subsequent chargeable device positioned within the charging region;
- and
- adjusting the current from the first level to a default level prior to communication with the subsequent chargeable device.
An apparatus for wireless power transfer, the apparatus comprising:
- means for wirelessly transmitting power, using a current at a first level, sufficient to provide power to one or more chargeable devices positioned within a charging region;
- means for detecting a subsequent chargeable device positioned within the charging region;
- and
- means for adjusting the current from the first level to a default level prior to communication with the subsequent chargeable device.
A non-transitory computer-readable medium including computer-executable instructions thereon, the computer-executable instructions comprising instructions for:
- wirelessly transmitting power from a power transmitting element, using a current at a first level, sufficient to provide power to one or more chargeable devices positioned within a charging region of the power transmitting element;
- detecting a subsequent chargeable device positioned within the charging region;
- and
- adjusting the current from the first level to a default level prior to communication with the subsequent chargeable device.
