Problems solved by technology

However, these systems add cost and complexity to remote devices and wireless power
Also, the long-range capabilities of RF communication systems may result in communication with remote devices that are not present in the vicinity of the wireless power source
For example, if two wireless power supplies both associated with a remote device to be charged are located in the same house and use an RF communication system, there may be communication errors with the remote device during power transfer

[0088] In the third embodiment of the present invention, the wireless power supply and remote device systems and methods are similar to those described herein with respect to wireless power supply 10 and remote device 12, with some exceptions. This third embodiment may employ systems and methods similar to those in the current embodiment, and may further include wireless power supply 10 configured to request remote device 12 to reduce its power consumption. If certain criteria are met: (a) if the maximum power available to wireless power supply 10 is reached, (b) if wireless power supply 10 determines that a foreign object is present in the active magnetic field, (c) if another remote device 12 requests a reduction in the magnetic field An urgent need for power, or (d) if wireless power supply 10 detects an overtemperature condition in itself, wireless power supply 10 may request remote device 12 to reduce its consumption.

[0090] In a fourth embodiment of the present invention, the wireless power supply and remote device systems and methods are similar to those described herein with respect to wireless power supply 10 and remote device 12, with some exceptions. This fourth embodiment may employ systems and methods similar to those in the current embodiment, and may further include a remote device 12 that can change the impedance of its modulating element according to configuration.

[0091] In this embodiment, for example, if a remote device 12 wishes to send a high-priority message, it may employ a separate or additional modulator that causes a modulation large enough to overwhelm the other remote device's 12 modulators, and may decide to Send information at any point without waiting for its allocated time slot. If the remote device 12 has determined that there are multiple powered remote devices 12 and the wireless power supply 10 has been unable to receive communication packets sent by the re...

[0093] In a fifth embodiment of the present invention, the wireless power supply and remote device systems and methods are similar to those described herein with respect to wireless power supply 10 and remote device 12, with some exceptions. In this embodiment, a non-standard device (eg, a remote device 12 capable of receiving and controlling power but not utilizing the current communication embodiment) is detected and powered using a communication protocol supported by the non-standard device.

[0094] Wireless power source 10 may be configured to detect remote devices 12 that are capable of receiving wireless power and communicating, but may not be able to receive communications from wireless power source 10 . The wireless power supply 10 may detect these remote devices 12 using its identification information sent during the communication, or because the communication packet was not received by the wireless power supply 10 during the allocated time slot. In this case, the wi...

Abstract

The present invention relates to wireless power supplies adapted to supply power and communicate with one or more remote devices. The systems and methods of the present invention generally relate to a communication timing system that may ensure information being communicated does not overlap with that of another device, preventing data collisions and information from going undetected. With information being communicated in a way that addresses or avoids potential communication issues in multiple device systems, the wireless power supply may control operation to effectively supply wireless power.

Description

technical field [0001] The present invention relates to wireless power systems, and more particularly to systems and methods for communicating in wireless power systems. Background technique [0002] Many traditional wireless power systems rely on inductive power transfer to transfer power without the use of wires. A typical inductive power transfer system includes an inductive power supply that uses a primary coil (or transmitter) to wirelessly transfer energy in the form of a changing electromagnetic field and a remote device that uses a secondary coil (or receiver) to convert this energy in the electromagnetic field into electrical energy . Recognizing the potential advantages, some researchers have focused on making wireless power systems with adaptive control systems. Adaptive control systems can provide wireless power supplies with the ability to adapt operating parameters over time to maximize efficiency and / or control the amount of power delivered to remote devices...
