Abstract

The embodiment of the invention provides electronic equipment, wireless charging equipment and a wireless charging method, and belongs to the technical field of charging. The electronic equipment comprises a receiving coil, a receiving circuit, a first switch module and a first control module. The first control module is used for controlling on-off of at least two first switches in the first switch module according to the parameters relevant to the magnetic coupling strength between the receiving coil and an emitting coil of the wireless charging equipment, so that the number of turns of sub coils of effective working in the receiving coil is adjusted. According to the electronic equipment, the wireless charging equipment and the wireless charging method, the number of the turns of the subcoils of effective working in the receiving coil is adjusted according to the magnetic coupling strength between the emitting coil and the receiving coil, and therefore temperature rising of equipment in the charging process is lowered by adjusting the effective impedance of the coils.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of charging, and in particular, to an electronic device, a wireless charging device, and a wireless charging method. Background technique [0002] With the development of the wireless charging technology, the application of the wireless charging function in the terminal equipment becomes more and more popular. One of the main technical development directions of wireless charging technology currently applied to smart terminal devices is to increase charging power, that is, wireless fast charging technology, which can shorten the charging time of terminal devices, thereby improving the user's charging experience. [0003] However, in the current terminal equipment, the development of wireless fast charging technology is limited due to the unsolved temperature rise of the equipment, and one of the main reasons for the temperature rise during the charging process is the coil. In order ...
