METHOD AND APPARATUS FOR CONTROLLING WIRELESS POWER TRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18355897 titled 'METHOD AND APPARATUS FOR CONTROLLING WIRELESS POWER TRANSMISSION
Simplified Explanation
This patent application describes a method for transmitting power wirelessly from a transmitter to a receiver. The method includes several phases of determining whether a foreign object is present in the charging area and controlling the power transmission accordingly.
- The method starts with the receiver sending a signal to the transmitter, including information about the presence of a foreign object (FOD) in the charging area.
- Based on the FOD status packet, the transmitter determines whether a foreign object is present in the charging area.
- If a foreign object is detected, the transmitter controls the power transmission in a first power transfer mode.
- If no foreign object is detected, the transmitter controls the power transmission in a second power transfer mode.
- Additionally, the transmitter can use other information, apart from the FOD status packet, to determine the presence of a foreign object in the charging area.
- The power transmission mode is adjusted based on the determination made in the second phase, while considering the power control phase.
Overall, this patent application presents a method for wireless power transmission that takes into account the presence of foreign objects in the charging area and adjusts the power transmission mode accordingly.
Original Abstract Submitted
A method of transmitting power of a wireless power transmitter, including a receiving phase of receiving a signal including an FOD status packet from a wireless power receiver; a first determination phase of determining whether a foreign object is present in a charging area of the wireless power transmitter based on the FOD status packet; a power control phase of controlling power transmission in a first power transfer mode upon determining that the foreign object is present in the charging area in the first determination phase, or controlling power transmission in a second power transfer mode upon determining that the foreign object is not present in the charging area in the first determination phase; and a second determination phase of determining whether the foreign object is present in the charging area based on information other than information included in the FOD status packet, while controlling power transmission in one of the first power transfer mode and the second power transfer mode by the power control phase.
