Abstract

An operating method includes receiving a power signal from a power providing equipment, transmit a first end power transfer message to the power providing equipment under a condition that the power of the battery is full, so that the power providing equipment stops providing the wireless power signal according to the first end power transfer message; charging the battery by utilizing the wireless power signal under a condition that the power of the battery is not full; and transmitting a second end power transfer message to the power providing equipment under a condition that the battery is fully charged by the charging module, so that the power providing equipment stops providing the wireless power signal according to the second end power transfer message. The first end power transfer message and the second end power transfer message are different.

Claims

1. A mobile device comprises:

a battery;

a wireless power receiver configured for receiving a wireless power signal from a power providing equipment;

a communication transmitter;

a charging module; and

a processor electrically connected with the battery, the wireless power receiver, the communication transmitter, and the charging module, wherein the processor is configured for;

controlling the communication transmitter to transmit a first end power transfer message to the power providing equipment under a condition that the power of the battery is full at a beginning of the wireless power receiver receiving the wireless power signal from the power providing equipment, so that the power providing equipment stops providing the wireless power signal according to the first end power transfer message;

controlling the charging module to charge the battery by utilizing the wireless power signal received from the power providing equipment under a condition that the power of the battery is not full; and

controlling the communication transmitter to transmit a second end power transfer message to the power providing equipment under a condition that the battery is fully charged by the charging module, so that the power providing equipment stops providing the wireless power signal according to the second end power transfer message;

wherein the first end power transfer message and the second end power transfer message are different, so that the power providing equipment determines whether the mobile device is replaced by another mobile device according to the first end power transfer message and the second end power transfer message.

2. The mobile device as claimed in claim 1, wherein formats of the first end power transfer message and the second end power transfer message are different.

3. The mobile device as claimed in claim 1, wherein payloads of the first end power transfer message and the second end power transfer message are different.

4. The mobile device as claimed in claim 1, wherein headers of the first end power transfer message and the second end power transfer message are different.

5. The mobile device as claimed in claim 1, wherein an order of a header and a payload of first end power transfer message is different from an order of a header and a payload of the second end power transfer message.

6. The mobile device as claimed in claim 1, wherein the processor is further configured for:

controlling the communication transmitter to transmit identification information of the mobile device to the power providing equipment under a condition that the battery is not full at the beginning of the wireless power receiver receiving the wireless power signal from the power providing equipment.

7. The mobile device as claimed in claim 5, wherein the processor is further configured for:

controlling the communication transmitter to transmit a control error packet to the power providing equipment periodically after transmitting the identification information of the mobile device.

8. A power providing equipment comprises:

a wireless power transmitter configured for transmitting a wireless power signal to a mobile device;

a communication receiver; and

a processor electrically connected with the wireless power transmitter and the communication receiver, wherein the processor is configured for;

determining whether a first end power transfer message from the mobile device is received, wherein the first end power transfer message indicates a power of a battery of the mobile device is full at a beginning of the wireless power transmitter transmitting the wireless power signal to the mobile device;

controlling the wireless power transmitter to stop transmitting the wireless power signal to the mobile device under a condition that the first end power transfer message is received;

receiving, through the communication receiver, a second end power transfer message from the mobile device under a condition that the battery is fully charged by utilizing the wireless power signal transmitted from the wireless power transmitter;

controlling the wireless power transmitter to stop the power signal corresponding to the second end power transfer message; and

determining whether the mobile device is replaced by another mobile device according to the first end power transfer message and the second end power transfer message;

wherein the first end power transfer message and the second end power transfer message are different.

9. The power providing equipment as claimed in claim 8, wherein formats of the first end power transfer message and the second end power transfer message are different.

10. The power providing equipment as claimed in claim 8, wherein payloads of the second end power transfer message and the first end power transfer message are different.

11. The power providing equipment as claimed in claim 8, wherein headers of the second end power transfer message and the first end power transfer message are different.

12. The power providing equipment as claimed in claim 8, wherein an order of a header and a payload of the second end power transfer message is different from an order of a header and a payload of the first end power transfer message.

13. The power providing equipment as claimed in claim 8, wherein the processor is further configured for:

receiving identification information of the mobile device from the mobile device under a condition that the power of the battery is not full at the beginning of the wireless power transmitter transmitting the wireless power signal to the mobile device.

14. The power providing equipment as claimed in claim 13, wherein the processor is further configured for:

determining whether the mobile device is replaced by another mobile device according to whether the first end power transfer message is received after receiving the identification information of the mobile device from the mobile device.

15. The power providing equipment as claimed in claim 8, wherein the processor is further configured for:

receiving another first end power transfer message from another mobile device after charging the battery of the mobile device; and

determining the mobile device is replaced by the another mobile device according to the another first end power transfer message.

16. An operating method of a mobile device, the operating method comprising:

receiving a power signal from a power providing equipment;

transmit a first end power transfer message to the power providing equipment under a condition that the power of the battery is full at a beginning of receiving the wireless power signal from the power providing equipment, so that the power providing equipment stops providing the wireless power signal according to the first end power transfer message;

charging the battery by utilizing the wireless power signal received from the power providing equipment under a condition that the power of the battery is not full;

transmitting a second end power transfer message to the power providing equipment under a condition that the battery is fully charged by the charging module, so that the power providing equipment stops providing the wireless power signal according to the second end power transfer message; and

determining whether the mobile device is replaced by another mobile device according to the first end power transfer message and the second end power transfer message;

wherein the first end power transfer message and the second end power transfer message are different.
