Abstract

The invention provides a wireless charging control method and a wireless charging device. The movement of a transmitting coil is controlled according to the change of the currently acquired real-timequality factor value and the inherent quality factor value of the transmitting coil and the change of the previously acquired real-time quality factor value; then, when the currently obtained real-time quality factor value is less than a preset quality factor value, whether the transmission power is higher than the preset efficiency or not is compared; and the movement of the transmitting coil iscontrolled below the preset efficiency, and the transmitting coil is adjusted to the optimal position point. The design of a PCB with a plurality of signal detection coils in the prior art is removedby a detection circuit sharing the wireless charging power, the number of laminated layers of the transmitting coil is reduced, the wireless charging efficiency is improved, and the overall design cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile wireless charging, in particular to a wireless charging control method and a wireless charging device. Background technique [0002] Wireless charging technology has been more and more widely used due to its advantages of non-contact and fast charging. One of the existing wireless charging technologies is non-mobile, and the transmitting coil of the non-mobile wireless charging technology is fixed. When a single transmitting coil is charged, the chargeable area is small. When multiple transmitting coils are used, although the charging area increases, each transmitting coil of the multiple transmitting coils is still fixed, and the chargeable area of ​​each transmitting coil is not large. Change, when large-area charging is required, the more the number of transmitting coils, in order to solve the dead zone of charging, the more stacked layers of transmitting coils are required, at least three layer...
