Problems solved by technology

So now wireless charging is becoming more and more popular, but in the process of using wireless charging, because wireless charging has lower charging efficiency and charging utilization rate than wired charging, charging the same amount of power will consume more power, and wireless charging The charging efficiency and charging utilization rate of charging are related to the placement of the electric device. The location of the electric device is different, and the overlapping area of ​​the charging coil of the electric device and the charging coil of the wireless charging device is different, which will cause a part of the charging energy to be wasted, and when used It cannot be guaranteed that each placement is the largest overlapping area, so that the charging efficiency and charging utilization rate during the charging process are maximized

Embodiment 1

[0078] This embodiment provides a wireless charging method, including the following content:

[0079] The charging coil of the terminal includes several channels, and the charging coil of the wireless charging device includes several charging channels. In the process of wireless charging between the terminal and the wireless charging device, adjust the channels of the charging coil of the terminal and the channel of the charging coil of the wireless charging device to carry out Loop matching, so that each channel of the charging coil of the terminal matches each channel of the charging coil of the wireless charging device one by one to form different charging methods, and obtain the charging utilization rate of each charging method; according to the charging of each charging method Utilization rate, obtain the maximum charging utilization rate, and adjust the channel of the charging coil of the terminal and the channel of the charging coil of the wireless charging device to the...

Embodiment 2

[0100] This embodiment is basically the same as the above embodiment, the difference is that before the terminal activates the channel T1 of the charging coil, it also includes:

[0101] Divide the charging coil of the wireless charging device into several schemes;

[0102] The wireless charging device activates the full-power coils in each scheme one by one to charge the terminal;

[0103] Obtain the charging utilization rate corresponding to each scheme;

[0104] According to the charging utilization rate of each scheme, the scheme with the maximum charging utilization rate is obtained;

[0105] For the terminal and the wireless charging device, in the scheme with the maximum charging utilization rate, the terminal activates the channel T1 of the charging coil, and then only matches the channel under the scheme with the maximum charging utilization rate, thereby reducing the amount of matching calculations and saving operating resources. For example: as shown in the figure...

Embodiment 3

[0107] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, the terminal adjusts the channel step by step at each preset interval time, and after adjusting to the last stage channel Tm, the preset interval time is set. Adjust the channel to T1, and continue to adjust step by step; every m preset intervals of the wireless charging device, the terminal adjusts the channel step by step, and after adjusting to the last level of channel Sn, the interval n preset intervals end step by step Level adjustment, so that each channel of the wireless charging device and the terminal can also be matched one by one.

Abstract

The invention relates to the technical field of wireless charging, in particular to a wireless charging system, device and method, and the method comprises the steps that: a charging coil of a terminal comprises a plurality of channels, a charging coil of the wireless charging device comprises a plurality of charging channels, and in the wireless charging process of the terminal and the wireless charging device, a channel of a charging coil of the terminal and a channel of a charging coil of the wireless charging device are adjusted, and cyclic matching is performed, so that each channel of the charging coil of the terminal is matched with each channel of the charging coil of the wireless charging device one by one, different charging modes are formed, and a charging utilization rate of each charging mode is obtained; and according to the charging utilization rate of each charging mode, the maximum charging utilization rate is obtained, and the channel of the charging coil of the terminal and the channel of the charging coil of the wireless charging device are adjusted to be the charging mode with the maximum charging utilization rate, and wireless charging is performed. According to the scheme, the maximum charging utilization rate can be automatically found, the charging utilization rate is improved, and charging electric energy waste is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging system, equipment and method. Background technique [0002] Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method for charging mobile phones; high-power wireless charging often uses resonance to transmit energy from the power supply equipment to the power-consuming device, and the device uses the received energy to charge the battery. And at the same time, it is used for its own operation, for example: the charging method of electric vehicles. [0003] Wireless charging uses a magnetic field to transmit energy between the charging device and the power-consuming device, and there is no need for wires to connect the two. Therefore, both the...
