Embodiment 1

[0081] see figure 2 , shows the wireless charging control method in the first embodiment of the present invention, which is applied to the wireless charging module, and the method includes steps S10-S13.

[0082] Step S10, when it is detected that the terminal to be charged is connected, wirelessly charge the terminal to be charged with a first charging current.

[0083] Among them, the terminal to be charged includes electric devices that can perform wireless charging, such as mobile phones, tablet computers, and electronic watches. "Connecting the terminal to be charged" means that the terminal to be charged can start wireless charging. When the terminal is a mobile phone and the wireless charging module adopts the principle of electromagnetic induction, the mobile phone is placed on the placement panel corresponding to the charging area in the wireless charging module and the wireless charging module detects that the mobile phone is placed on the placement panel correspond...

Embodiment 2

[0099] see image 3 , shows the wireless charging control method in the second embodiment of the present invention, which is applied to the wireless charging module, and the method includes steps S20-S26.

[0100] Step S20, when it is detected that the terminal to be charged is connected, wirelessly charge the terminal to be charged by using a first charging current.

[0101] Step S21 , acquiring a current loss value during the wireless charging of the terminal to be charged with the first charging current.

[0102] Step S22, judging whether the current loss value is higher than the preset current loss threshold every preset time; if so, execute step S23.

[0103] Specifically, in actual situations, there may be cases where the vehicle shakes frequently during driving on a certain road section, causing the terminal to be charged to move back and forth between the charging area of ​​the wireless charging module and the edge of the charging area. The value is compared with the...

Embodiment 3

[0116] see Figure 4 , shows the wireless charging control method proposed in the third embodiment of the present invention, which is applied to the wireless charging module, and the method includes steps S30-S39.

[0117] Step S30, when it is detected that the terminal to be charged is connected, wirelessly charge the terminal to be charged by using a first charging current.

[0118] Step S31 , acquiring a current loss value during the wireless charging of the terminal to be charged with the first charging current.

[0119] Step S32, judging whether the current loss value is higher than a preset current loss threshold; if yes, execute step S33.

[0120] Step S33, acquiring location information of the terminal to be charged in the charging area of ​​the wireless charging module;

[0121] Specifically, in actual situations, there are many situations that cause current loss, for example, when the terminal to be charged is at the edge of the charging area of ​​the wireless char...

Abstract

The invention discloses a wireless charging control method, device, readable storage medium and charging equipment. The method is applied to a wireless charging module. The method includes: when detecting that a terminal to be charged is connected, passing a first charging current Perform wireless charging on the terminal to be charged; during the process of charging the terminal to be charged with the first charging current, obtain a current loss value; determine whether the current loss value is higher than a preset current loss threshold ; If so, reduce the first charging current to a second charging current, and wirelessly charge the terminal to be charged through the reduced current; wherein, the second charging current is within the first preset current range . The invention solves the problem in the prior art that the charging of the mobile phone is interrupted due to deviation from the charging area during charging.

Description

technical field [0001] The present invention relates to the technical field of vehicle charging, in particular to a wireless charging control method, device, readable storage medium and charging equipment. Background technique [0002] Wireless charging technology (Wireless charging technology; Wireless charge technology) is derived from wireless power transmission technology. Due to the high safety, convenience, high reliability and timely advantages of wireless charging technology, wireless charging has also received more and more people's favor. [0003] In the prior art, affected by the size of the mobile phone and the interior shape of the vehicle, the mobile phone placement panel of the vehicle wireless charging module has a larger area than the wireless charging coil, and most of the wireless charging coils are placed on the mobile phone placement panel of the wireless charging module When the mobile phone moves to the edge of the panel due to certain factors (such a...
