WIRELESS POWER TRANSMISSION CONTROL METHOD AND DEVICE

Japanese Patent JP2023134685

A

To provide a wireless power transmission control method and a device capable of preventing unnecessary interruption of charging by minimizing foreign object detection errors.SOLUTION: A method includes: a first packet receiving step of receiving a foreign object detection status packet; a first determination step of determining whether a foreign object is present based on the foreign object detection status packet; and a power control step of controlling power based on a determination result of the first determination step. The power control step includes a first power transmission mode in which a first power is transmitted when it is determined that there is a foreign object as a result of the determination in the first determination step, and a second power transmission mode in which a second power is transmitted when it is determined that there is no foreign object as a result of the determination in the first determination step.SELECTED DRAWING: Figure 5
