Abstract

The invention provides a wireless charging sending device, a wireless charging system and a charging control method thereof. The sending device comprises an emission coil used for emitting electricity energy of the sending device, an oscillating and frequency-modulating module used for enabling the emission coil to generate LC resonance and modulating the capacitance in the LC resonance so as to change the resonance frequency of the LC resonance, an emission end sampling module used for collecting voltage and currents of the sending device, a first control module used for controlling the resonance frequency of the LC resonance in the oscillating and frequency-modulating module and controlling the charging energy sending process according to the collected voltage and the collected currents of the sending device, the voltage of a receiving device and resonance frequency corresponding to the highest charging efficiency, a first communication module used for wireless communication between the sending device and the receiving device, and a power supply module. The sending device, the charging system and the charging control method can realize the adjustment of the resonance frequency of the LC resonance so as to have the advantage of improving the charging efficiency of the charging system.

Description

technical field [0001] The present invention relates to the field of wireless charging, in particular to a wireless charging sending device, a wireless charging system, and a wireless charging control method thereof. Background technique [0002] At present, the application range of mobile terminals is more and more extensive, with powerful functions and excellent convenience, such as mobile phones, IPADs, and rechargeable 3D glasses, which are rich in entertainment, such as watching TV, surfing the Internet, singing, etc. . In the process of using a mobile terminal, due to the limitation of the battery capacity, the battery power will be used up soon. For example, the battery life of the mobile phone with the Android system, which is currently popular among users, is relatively poor. to recharge, so always bring a spare battery or wired charger with you. Many mobile terminals need to carry wired chargers to charge the battery, and wired chargers are cumbersome because of ...
