Wireless charging system and wireless charging method

Abstract

The present invention provides a wireless charging system. The wireless charging system comprises a transmitting terminal and a receiving terminal. The transmitting terminal comprises a source terminal rectification module, a source terminal DC / DC module, an inversion module, an emission coil, a detection module configured to measure an output voltage of the source terminal DC / DC module, a networkmodule, a server module configured to perform information transfer and a master control module. The receiving terminal comprises a receiving coil, a secondary terminal rectification module, a secondary terminal DC / DC module, a battery and a client module configured to input rate voltage information of the battery; the master control module controls the source terminal DC / DC module according to the rated voltage information, especially, the master control module determines a coupling coefficient when the battery is charged, and when it is determined that the coupling coefficient is changed, the output voltage of the source terminal DC / DC module is regulated to maintain the output voltage of the battery as a rated voltage. The source terminal DC / DC module is controlled to achieve instant regulation of the output voltage of the transmitting terminal in the charging process, and therefore, the problem is solved that the control of the wireless charging technology is not convenient and thecharging efficiency of the wireless charging system is ensured.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless charging system. Background technique [0002] Wireless charging technology is a new technology. Compared with the traditional wired charging method, wireless charging is more convenient and safe, especially because it is not limited by wires, chargers, sockets and other factors, wireless charging technology is very convenient to use. At present, the wireless charging technology adopts open-loop control or manual control, that is, the process is not controlled during charging, and even if it is controlled, the transmitting part is controlled manually, which reduces the convenience of wireless charging. At the same time, the resistance of the load battery will change during the charging process, or the resistance of the load battery will be different for different charging objects, which will reduce the efficiency of wireless charging and cause a serious waste of power ...

AI Technical Summary

Problems solved by technology

At present, the wireless charging technology adopts open-loop control or manual control, that is, the process is not controlled during charging, and even if it is controlled, the transmitting part is controlled manually, which reduces the convenience of wireless charging.

At the same time, the resistance of the load battery will change during the charging process, or the resistance of the load battery will be different for different charging objects, which will reduce the efficiency of wireless charging and cause a serious waste of power resources.

Especially in wireless charging in a dynamic environment, the position of the load battery and the wireless power supply changes, and it is difficult to guarantee the charging efficiency of the wireless system
