Testing device for testing wireless power transmitter device and associated method

1. A testing device for testing a wireless power transmitter device having at least one power transmitter coil, wherein the testing device comprises at least one wireless power receiver coil and wherein the testing device is in operative communication with a processing means having an associated memory, wherein the testing device is configured to:

receive a power signal applied by the wireless power transmitter device;

in response to receiving the power signal, transmit a first packet to the wireless power transmitter device, wherein the first packet is a signal strength packet;

transmit a second packet to the wireless power transmitter device when the wireless power transmitter device continues to transmit the power signal to the testing device in response to receiving the signal strength packet,

characterized in that

the processing means is configured to:

determining whether the wireless power transmitter device continues to transmit the power signal to the testing device in response to the signal strength packet;

when the wireless power transmitter device continues to transmit the power signal to the testing device in response to the signal strength packet, store the signal strength packet or store signal strength value(s) of the signal strength packet in the memory; and

when the wireless power transmitter device fails to continue to transmit the power signal to the testing device in response to the signal strength packet;

not save the signal strength value(s) of the signal strength packet in the memory; or

save the strength value(s) of the signal strength packet in the memory with a disregard indicator.

2. The testing device as defined in claim 1 , wherein the second packet is an identification packet.

3. The testing device as defined in claim 1 , wherein the second packet is an end power transfer packet.

4. The testing device as defined in claim 1 , wherein the signal strength packet comprises at least one value.

5. The testing device as defined in claim 1 , wherein the processing means and its associated memory are arranged in the testing device.

6. The testing device as defined in claim 1 , wherein the processing means and its associated memory are arranged in a host device being in communication with the testing device.

7. The testing device as defined in claim 1 , wherein the testing device is a consumer device being configured with a test mode.

8. The testing device as defined in claim 7 , wherein the consumer device is one of a mobile terminal, a tablet computer or a laptop computer.

9. The testing device as defined in claim 2 , wherein the signal strength value is stored in the memory with an indicator indicating power transfer phase when the wireless power transmitter device, in response to said received identification packet, continues to transmit the power signal to the testing device.

10. The testing device as defined in claim 1 , wherein the processing means is further configured to evaluate the stored signal strength packet(s) or value(s) thereof.

11. The testing device as defined in claim 10 , wherein the evaluation of the stored signal strength packet(s) or value(s) thereof relates to providing feedback to the user of the testing device.

12. The testing device as defined in claim 11 , wherein the feedback relates to re-positioning the testing device on the wireless power transmitter device.

13. The testing device as defined in claim 11 , wherein the processing means is further configured to evaluate the stored signal strength packet(s) or value(s) thereof and to transmit a movement signal to a robotic arm instructing said robotic arm to reposition the testing device on the wireless power transmitter device.

14. The testing device as defined in claim 1 , wherein the wireless power transmitter device is in the form of a wireless charger.

15. A method for evaluating testing of a wireless power transmitter device having at least one power transmitter coil, the method comprising:

providing a testing device having at least one wireless power receiver coil;

receiving, from the wireless power transmitter device, a power signal at the testing device,

in response to receiving the power signal, transmitting, by the testing device, a first packet to the wireless power transmitter device, wherein said first packet is a signal strength packet;

transmitting, by the testing device, a second packet to the wireless power transmitter device when the wireless power transmitter device continues to transmit the power signal to the testing device in response to receiving the signal strength packet,

determine whether the wireless power transmitter device continues to transmit the power signal to the testing device in response to said signal strength packet;

when the wireless power transmitter device continues to transmit the power signal to the testing device in response to said signal strength packet, storing the signal strength packet or storing signal strength value(s) thereof in a memory; and

when the wireless power transmitter device fails to continue to transmit the power signal to the testing device in response to said signal strength packet;

not save the signal strength value(s) of the signal strength packet in the memory; or

save the signal strength value(s) of the signal strength packet in the memory with a disregard indicator.

16. A computer readable storage medium encoded with instructions that, when loaded and executed by a processing means, cause the method according to claim 15 to be performed.

17. A computer program product comprising code instructions which, when loaded and executed by a processing means, cause the method according to claim 15 to be performed.
