Problems solved by technology

However, using the receiving end to detect the temperature usually only checks the battery temperature or the internal temperature of the system. As long as the battery temperature does not exceed the standard, it will always communicate with the sending end. If the ambient temperature is too high at this time, it will be very dangerous and easily cause damage to the sending end. or catch fire

Embodiment 1

[0056] refer to figure 1 , which shows a structural block diagram of a wireless charger embodiment 1 provided by the embodiment of the present invention, which may specifically include a sending end and a receiving end, wherein the sending end may specifically include the following modules:

[0057] A communication module 101, configured to determine whether to communicate with the receiving end;

[0058] A temperature detection module 102, configured to detect the temperature of the sending end when communicating with the receiving end;

[0059] A control module 103, configured to determine whether the temperature of the sending end is greater than a preset threshold;

[0060] A charging module 104, configured to charge the receiving end when the temperature of the sending end is less than or equal to a preset threshold;

[0061] The over-temperature protection module 105 is configured to stop charging the receiving end when the temperature of the sending end is greater tha...

Embodiment 2

[0066] Embodiment 2 of a wireless charger provided by the embodiment of the present invention may specifically include a sending end and a receiving end, wherein the sending end may specifically include the following modules:

[0067] A communication module, configured to determine whether it is connected to the receiving end;

[0068] Specifically, the sending end can detect the placement or departure of the receiving end. When the sending end detects that the receiving end is placed, the sending end further detects whether it is connected to the receiving end. As a preferred example of the embodiment of the present invention, the sending end can use Check whether it is connected to the receiving end in the following way: the sending end sends a ping command to the receiving end, and after receiving the ping command, the receiving end returns its own response command to the sending end, and the sending end checks whether the response command is Comply with the wireless chargi...

Embodiment 3

[0084] Embodiment 3 of a wireless charger also provided by the embodiment of the present invention may specifically include a sending end and a receiving end, wherein the sending end may specifically include the following modules:

[0085] A communication module, configured to determine whether it is connected to the receiving end;

[0086] A temperature detection module is used to detect the temperature of the sending end when communicating with the receiving end;

[0087] A control module, configured to determine whether the temperature of the sending end is greater than a preset threshold; a charging module, configured to charge the receiving end when the temperature of the sending end is less than or equal to a preset threshold;

[0088] An over-temperature protection module, configured to stop charging the receiving end when the temperature of the sending end is greater than a preset threshold.

[0089] The temperature detection module of the embodiment of the present in...

Abstract

The embodiment of the invention provides a method for charging by utilizing a wireless charger and the wireless charger, wherein the wireless charger comprises a transmitting end and a receiving end; the transmitting end comprises a communication module, a temperature detection module, a control module, a charging module and over-temperature protection module; the communication module is used for judging whether the transmitting end communicates with the receiving end or not; the temperature detection module is used for detecting the temperature of the transmitting end after the transmitting end is communicated with the receiving end; the control module is used for judging whether the temperature of the transmitting end is higher than a preset threshold or not; the charging module is used for charging the receiving end when the temperature of the transmitting end is lower than or equal to the preset threshold; and the over-temperature protection module is used for stopping charging the receiving end when the temperature of the transmitting end is higher than the preset threshold. The embodiment of the method and the wireless charger can detect the surface temperature of the transmitting end, so that the wireless charging is enabled to be more reliable and safer.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless charging, and in particular, relate to a charging method using a wireless charger, a wireless charger, and a device. Background technique [0002] With the increasing popularity of battery-powered consumer electronic devices such as portable media players, smartphones, and tablets, wireless charging technology has been attracting attention after several years of promotion and evolution. Wireless charging refers to a device with a battery that obtains power through wireless induction for charging. There are three main principles of wireless charging today, including electromagnetic induction, radio waves, and electromagnetic resonance. At this stage, it is truly commercialized and widely used. The application is the type of electromagnetic induction. [0003] The wireless charging electromagnetic induction system is divided into two parts: the receiving end and the sending end. The re...
