Document Type and Number:
WIPO Patent Application WO/2023/160206
Kind Code:
A9
Abstract:
The present application relates to the technical field of wireless charging. Provided are a charging coil assembly and a wireless charging apparatus. The charging coil assembly comprises: a first charging coil and a second charging coil, wherein the first charging coil and the second charging coil partially overlap, the first charging coil works, the second charging coil does not work, and the charging current in the first charging coil excites a first induced current in the second charging coil; moreover, a first interference current, other than the first induced current, caused by interference is generated in the second charging coil; and the first charging coil and the second charging coil are arranged in opposite directions, and since the second charging coil and the first charging coil are arranged in opposite directions, the direction of the first induction current in the second charging coil is opposite to the direction of the first interference current in the second charging coil. By means of the charging coil assembly, an interference signal in a secondary coil can be reduced, thereby reducing the interference of the interference signal to a power source.
