Description

technical field [0001] The present application relates to the field of wireless charging, in particular to a wireless charging device and a charging method. Background technique [0002] The wireless charging technology of WPC or Qi protocol is based on the near-field magnetic induction method, which induces energy from the primary coil to the secondary coil, so as to achieve the purpose of wireless power transmission. In order to improve the system efficiency of wireless charging, it is usually required that the coils at the transmitting end and the receiving end must be as aligned and as close as possible. Although wireless charging based on the Airfuel protocol does not require perfect alignment, it will lead to a significant drop in charging efficiency. Therefore, whether it is WPC or Airfuel, it is desirable to align the coils as much as possible to improve system efficiency. Wireless charging devices are usually limited by space or coil size, and the degree of freedo...
