Power receiving apparatus, power transmitting apparatus, control methods thereof, and a non-transitory computer-readable storage medium

A power transmitting apparatus comprising:

• first transmitting unit configured to wirelessly transmit power to a power receiving apparatus;
• receiving unit configured to receive, from the power receiving apparatus, data to be used for first foreign object detection;
• determination unit configured to determine, based on the data received by the receiving unit, whether to execute second foreign object detection different from the first foreign object detection;
• second transmitting unit configured to transmit, to the power receiving apparatus, a response to the data received by the receiving unit;
• and
• foreign object detection unit configured to execute at least one of the first foreign object detection and the second foreign object detection in accordance with the determination of the determination unit.

A control method of a power receiving apparatus capable of receiving power transmitted from a power transmitting apparatus capable of executing first foreign object detection and second foreign object detection, the method comprising:

• transmitting, to the power transmitting apparatus, data to be used by the power transmitting apparatus to execute the first foreign object detection;
• before the data is transmitted, determining whether a predetermined condition for the power transmitting apparatus to execute the second foreign object detection different from the first foreign object detection is satisfied;
• and
• transmitting, to the power transmitting apparatus, a signal for causing the power transmitting apparatus to execute the second foreign object detection in accordance with the determination.

A control method executed by a power transmitting apparatus capable of transmitting power to a power receiving apparatus, the method comprising:

• receiving, from the power receiving apparatus, data to be used for first foreign object detection;
• determining, based on the received data, whether to execute second foreign object detection different from the first foreign object detection;
• transmitting, to the power receiving apparatus, a response to the received data received;
• and
• executing at least one of the first foreign object detection and the second foreign object detection.

A non-transitory computer-readable storage medium storing a program configured to cause a computer to operate a control method of a power receiving apparatus capable of receiving power transmitted from a power transmitting apparatus capable of executing first foreign object detection and second foreign object detection, the method comprising:

• transmitting, to the power transmitting apparatus, data to be used by the power transmitting apparatus to execute the first foreign object detection;
• before the data is transmitted, determining whether a predetermined condition for the power transmitting apparatus to execute the second foreign object detection different from the first foreign object detection is satisfied;
• and
• transmitting, to the power transmitting apparatus, a signal for causing the power transmitting apparatus to execute the second foreign object detection in accordance with the determination.

A non-transitory computer-readable storage medium storing a program configured to cause a computer to operate a control method of a power transmitting apparatus capable of transmitting power to a power receiving apparatus, the method comprising:

• receiving, from the power receiving apparatus, data to be used for first foreign object detection;
• determining, based on the received data, whether to execute second foreign object detection different from the first foreign object detection;
• transmitting, to the power receiving apparatus, a response to the received data;
• and
• executing at least one of the first foreign object detection and the second foreign object detection.
