Abstract
A power transmitting apparatus that transmits power to a power receiving apparatus executes intermittent wireless transmission of power. The power transmitting apparatus operates according to one of a first power transmitting method including detecting a signal load-modulated by the power receiving apparatus using an ID in response to the transmitted power during the intermittent transmission and a second power transmitting method including transmitting the power having modulated the power according to an ID determined in advance so that the power receiving apparatus detects the ID determined in advance.
Claims13
A power receiving apparatus that receives power from a power transmitting apparatus, the power receiving apparatus comprising:
- a power receiving unit configured to execute, using a first antenna, first wireless power reception, second wireless power reception whose power reception period is longer than a power reception period of the first wireless power reception, and third wireless power reception whose power is larger than the power of the first wireless power reception and the power of the second wireless power reception;
- and
- a communication unit configured to execute, using a second antenna different from the first antenna, communication with a power transmitting apparatus,
- wherein the power receiving unit starts the second wireless power reception after the power receiving unit executes the first wireless power reception, and
- wherein the power receiving unit executes the third wireless power reception based on the communication with the power transmitting apparatus by the communication unit, after the second wireless power reception is started.
A control method for a power receiving apparatus that receives power from a power transmitting apparatus, the method comprising:
- executing, using a first antenna, first wireless power reception, second wireless power reception whose power reception period is longer than a power reception period of the first wireless power reception, and third wireless power reception whose power is larger than the power of the first wireless power reception and the power of the second wireless power reception;
- and
- executing, using a second antenna different from the first antenna, communication with the power transmitting apparatus,
- wherein the second wireless power reception is started after the first power reception is executed, and
- wherein the third wireless power reception is executed based on the communication with the power transmitting apparatus using the second antenna, after the second wireless power reception is started.
A non-transitory computer-readable storage medium storing a program that causes a computer to:
- executing, using a first antenna, first wireless power reception, second wireless power reception whose power reception period is longer than a power reception period of the first wireless power reception, and third wireless power reception whose power is larger than the power of the first wireless power reception and the power of the second wireless power reception;
- and
- executing, using a second antenna different from the first antenna, communication with the power transmitting apparatus,
- wherein the second wireless power reception is started after the first power reception is executed, and
- wherein the third wireless power reception is executed based on the communication with the power transmitting apparatus using the second antenna, after the second wireless power reception is started.
