Based on the comparison result, when at least one terminal of the plurality of terminals has a different voltage value than that of the other at least one terminal, the power receiving device is in a state in which the power receiving device is disposed in a non-aligned upper part of the power transmitting device Power receiving device set to check. 8. The method of claim 7,
The processor is
The power receiver is set to output a guide for arranging the power receiver to be aligned on the top of the power receiver, based on it being determined that the power receiver is not aligned on the top of the power transmitter . A method for measuring a temperature of a power receiving device, the method comprising:
receiving power wirelessly from a power transmitting device;
checking the temperature of each of the plurality of terminals disposed adjacent to the power receiving coil and to which the first and second measurement signal lines are connected; and
and controlling the wirelessly received power based on it being determined that a temperature of at least one of the plurality of terminals exceeds a specified temperature. 12. The method of claim 11,
The first measurement signal line is formed of the same material as the power receiving coil. 12. The method of claim 11,
The second measurement signal line is formed of a material different from that of the first measurement signal line. 12. The method of claim 11,
Each of the plurality of terminals is disposed in an outer region, an inner region, and/or a central region of the power receiving coil. 12. The method of claim 11,
The operation of checking the temperature of each of the plurality of terminals is,
and determining a voltage value of each terminal based on a temperature difference between each of the plurality of terminals to which the first measurement signal line and the second measurement signal line are connected and a terminal of a measurement unit. 16. The method of claim 15,
The operation of checking the temperature of each of the plurality of terminals is,
analyzing a voltage level based on the voltage value of each of the terminals; and
and checking a temperature of each of the plurality of terminals corresponding to the voltage level. 16. The method of claim 15,
The method further comprising the operation of determining whether the power receiving device is in a state in which the power receiving device is arranged in a non-aligned upper portion of the power transmitting device based on the voltage value of each of the terminals. 18. The method of claim 17,
The operation of determining whether the power receiving device is in a state in which the power receiving device is in a non-aligned upper portion of the power transmitting device,
Based on the voltage value of at least one terminal among the voltage values of each of the plurality of terminals exceeding a specified voltage value, the operation of confirming that the power receiving device is in a state in which the power receiving device is unalignedly disposed on the top of the power transmitting device How to include. 18. The method of claim 17,
The operation of determining whether the power receiving device is in a state in which the power receiving device is in a non-aligned upper portion of the power transmitting device,
comparing voltage values of each of the plurality of terminals; and
Based on the comparison result, when at least one terminal of the plurality of terminals has a different voltage value than that of the other at least one terminal, the power receiving device is in a state in which the power receiving device is disposed in a non-aligned upper part of the power transmitting device A method that includes an action to check. 18. The method of claim 17,
The method further includes outputting a guide for arranging the power receiver to be aligned on the top of the power receiver, based on it being determined that the power receiver is not aligned on the top of the power transmitter How to.
