Embodiment 1

[0033] This embodiment provides a positioning method for wireless charging, such as figure 1 As shown, the method includes:

[0034] 101. Acquire an optimal charging current corresponding to the mobile terminal.

[0035] 102. Obtain the optimal charging current position on the wireless charging board.

[0036] Specifically, firstly, the mobile terminal is moved on any two intersecting straight lines on the wireless charging board, and the positions of the maximum charging current on the two straight lines are obtained respectively, so that the maximum charging current or the position of the optimal charging current can be calculated. Location. Generally, the magnitude of the charging current on the wireless charging board is radiating from the area where the maximum charging current is located. Therefore, as long as you know the position of the maximum charging current in the direction of any two intersecting straight lines on the wireless charging board, use these two The ...

Embodiment 2

[0053] This embodiment provides another positioning method for wireless charging, such as image 3 As shown, the method includes:

[0054] 301. Detect a change in charging current when the mobile terminal moves in a first moving direction of the wireless charging board.

[0055] 302. Prompt the user of the direction of the optimal charging current position in the first moving direction relative to the current mobile terminal location, and / or prompt the user of the optimal charging current position in the first moving direction.

[0056] Specifically, when the maximum charging current in the first moving direction is less than the optimal charging current of the mobile terminal, from the position of the maximum charging current in the first moving direction, in the second direction perpendicular to the first moving direction moving in two moving directions, and detecting the change of the charging current during the moving process in the second moving direction; prompting the ...

Abstract

The embodiment of the invention discloses a positioning method and a positioning device for wireless charging. The positioning method comprises the steps of: firstly, acquiring an optimal chargingcurrent corresponding to a mobile terminal; secondly, acquiring an optimal charging current position on a wireless charging board by the mobile terminal; and finally, prompting the direction of the optimal charging current position relative to a direction of a mobile terminal position and / or the optimal charging current position for a user. The positioning method is suitable for the field of communication systems.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a positioning method and device for wireless charging. Background technique [0002] Currently, charging a mobile terminal through wireless charging is being more and more widely used. However, when different types and models of mobile terminals are designed, the location of the internal wireless charging module (induction coil) is affected by the identification number ID design and structural design differently. Therefore, due to the different positions of the wireless charging module inside the mobile terminal, it is not easy to position the mobile terminal correctly when placed on the wireless charging board (especially for different types of charging boards from different manufacturers), resulting in low charging efficiency of the mobile terminal. Contents of the invention [0003] The invention provides a positioning method and device for wireless charging, which impro...
