Title:
AGGREGATED WIRELESS POWER TRANSFER WITH MULTIPLE COILS AND COMMUNICATION CHANNELS
Document Type and Number:
WIPO Patent Application WO/2021/102310
Kind Code:
A8
Abstract:
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for wireless power transmission. A wireless power transmission apparatus may transmit multiple wireless power signals to a wireless power reception apparatus configured to combine the power from the multiple wireless power signals. The wireless power reception apparatus may provide a combined wireless power signal to a load, such as a battery charger or electronic device. In some implementations, each set of primary coil and secondary coil may utilize low power wireless power signals (such as 15 Watts or less) in accordance with a wireless charging standard. By combining power from multiple low power wireless power signals, the wireless power reception apparatus may support higher power requirements of an electronic device. Multiple communication channels may be established between the wireless power transmission apparatus and the wireless power reception apparatus.
