Abstract: A method for controlling a power transmitting device is a method for detecting a metal foreign object by controlling the power transmitting device including a power transmitting coil that outputs power to a power receiving coil and a thermal sensor that measures a surface temperature of the metal foreign object on the power transmitting coil. The method includes causing the power transmitting coil to output the power before the coils are electromagnetically coupled with each other and a mobile object including the power receiving coil overlaps the power transmitting coil, causing the thermal sensor to measure the surface temperature of the metal foreign object, and transmitting, if the measured surface temperature of the metal foreign object is equal to or higher than a threshold, a signal indicating presence of the metal foreign object to another receiving apparatus, other than the power transmitting device, having a function of receiving the signal.

Abstract: A method for controlling a power transmitting device includes moving, if a mobile member holds a metal foreign object, the metal foreign object from a position overlapping a power transmitting coil to a position not overlapping the power transmitting coil by moving the mobile member from the position overlapping the power transmitting coil to a position not overlapping the power transmitting coil before the power transmitting coil begins to transmit power, causing the power transmitting coil to output the power, and moving, if another metal foreign object comes to a position overlapping the power transmitting coil when the mobile member is located at the position not overlapping the power transmitting coil, the other metal foreign object to a position not overlapping the power transmitting coil by returning the mobile member to the position overlapping the power transmitting coil in the state where the mobile member holds the foreign matter.

Abstract: A device including a power transmitting coil for providing electric power; a thermal sensor; and a circuit operative to: before start of transmitting first electric power for charging, cause the power transmitting coil to supply second electric power to a charging space; cause the thermal sensor to detect whether temperature in the charging space increases after the second electric power is transmitted; before start of transmitting the first electric power, determine chargeability based on presence information and foreign object information, the presence information indicating whether a mobile object is present in the charging space, and the foreign object information indicating whether the temperature in the charging space increases, and cause the power transmitting coil to transmit the first electric power in a case the circuit determines chargeable. The second electric power is lower than the first electric power, and the second electric power is supplied before the mobile object is located on the charging space.

Abstract: A power transmitting device includes a power transmitting coil for providing output power to a power receiving coil, a thermal sensor that detects a temperature around the power transmitting coil, and a power transmission control circuit that controls the power transmitting device. The power transmission control circuit causes the power transmitting coil to provide first output power, the power transmitting coil to provide second output power to the power receiving coil for charging a battery connected to the power receiving coil, the thermal sensor to detect the temperature around the power transmitting coil, and, if the detected temperature is equal to or higher than a threshold because of existing a metal foreign object, the power transmitting coil to reduce a level of the output power or stop the output power. The level of the first output power is lower than the level of the second output power
