Abstract

A system for high powered wireless power delivery and charging includes an electronic device having a wireless charging module. The wireless charging module includes a power management module, the power management module configured and executing instructions to enable and disable the power delivery or charging of the electronic device based on whether a valid charging circuit exists, the power management module additionally configured and executing instructions to prevent a detection of an invalid load.

Claims

an electronic device having a wireless power delivery module, the wireless power delivery module including;

a power management module, the power management module configured and executing instructions to enable and disable power delivery to the electronic device based on whether a valid constellation circuit exists, the power management module additionally configured and executing instructions to prevent a detection of an invalid load.

2. The system of claim 1, wherein the electronic device includes a plurality of contacts, the plurality of contacts creating a circuit for the power delivery when placed on a conductive power pad.

3. The system of claim 2, wherein the wireless power delivery module and the plurality of contacts are part of a case on the electronic device, and the wireless charging module is also in the case.

4. The system of claim 3, wherein the wireless power delivery module includes a constellation that is configured to detect that the valid constellation circuit exists, the constellation in communication with the power management module.

5. The system of claim 4, wherein the wireless power delivery module further includes a bypass-rectifier, the bypass-rectifier in communication with the power management module and configured to charge the electronic device when the valid constellation circuit exists.

6. The system of claim 5, wherein the power management module is configured and executing instructions to periodically turn on the constellation to detect the valid constellation circuit.

7. The system of claim 6, wherein the power management module turns on the bypass-rectifier when the valid constellation circuit is detected and the constellation is on.

8. The system of claim 7, wherein the wireless power delivery module includes a soft-start module, the soft-start module providing a delay for a ramping up of charging voltage for the bypass-rectifier when the valid constellation circuit is first detected.

9. The system of claim 1, wherein the power delivery includes charging a battery of the electronic device.

10. A case for high powered powering of an electronic device, the case comprising:

a case body;

a plurality of contacts on the case body for creating a circuit for charging when placed on a conductive power pad; and

a wireless power delivery module, the wireless power delivery module including;

a power management module, the power management module configured and executing instructions to enable and disable the charging of the electronic device based on whether a valid constellation circuit exists, the power management module additionally configured and executing instructions to prevent a detection of an invalid load;

wherein the wireless power delivery module includes a constellation that is configured to detect that a valid charging circuit exists, and the constellation is in communication with the power management module.

11. The case of claim 10, wherein the wireless power delivery module further includes a bypass-rectifier, the bypass-rectifier in communication with the power management module and configured to provide power to the electronic device when a valid constellation circuit exists.

12. The case of claim 11, wherein the power management module is configured and executing instructions to periodically turn on the constellation to detect the valid constellation circuit.
