背景技术Background technique
电磁感应式无线充电技术是目前最为常见的无线电力传输方式，通过电磁感应式无线充电装置的发射线圈与诸如手机等移动终端的接收线圈之间的电磁感应产生电流，从而将能量从电磁感应式无线充电装置传输到移动终端，为移动终端充电。Electromagnetic induction wireless charging technology is currently the most common wireless power transmission method. The electromagnetic induction between the transmitting coil of the electromagnetic induction wireless charging device and the receiving coil of mobile terminals such as mobile phones generates current, thereby transferring energy from the electromagnetic induction The wireless charging device transmits to the mobile terminal to charge the mobile terminal.
在现有技术中，电磁感应式无线充电装置包括一个或多个发射线圈以及移动终端支撑板，通常在移动终端被放置到移动终端支撑板上后，启动发射线圈为移动终端充电。In the prior art, an electromagnetic induction wireless charging device includes one or more transmitting coils and a mobile terminal support plate. Usually, after the mobile terminal is placed on the mobile terminal support plate, the transmitting coil is activated to charge the mobile terminal.
然而，在实际充电过程中，由于移动终端仅设置有一个接收线圈，因此，只能从电磁感应式无线充电装置的众多发射线圈中手动选择一个发射线圈为移动终端充电，且仅当接收线圈和发射线圈对准时，才能达到较高的充电效率，例如，将移动终端放置在电磁感应式无线充电装置的预制卡槽或卡座中，其中的预制卡槽或卡座用于确保将接收线圈和电磁感应式无线充电装置的一个发射线圈对准。当用户随手将移动终端放置在包括多个发射线圈的无线充电装置的移动终端支撑板上时，不能确保为移动终端充电的发射线圈是充电效率最高的发射线圈，从而导致充电效率较低和电力浪费。由此可见，现有的电磁感应式无线充电技术存在充电效率较低或充电操作不方便的问题。However, in the actual charging process, since the mobile terminal is only provided with one receiving coil, only one transmitting coil can be manually selected from the numerous transmitting coils of the electromagnetic induction wireless charging device to charge the mobile terminal, and only when the receiving coil and High charging efficiency can only be achieved when the transmitting coil is aligned. For example, the mobile terminal is placed in the prefabricated card slot or socket of the electromagnetic induction wireless charging device, and the prefabricated card slot or socket is used to ensure that the receiving coil and the A transmitting coil of the electromagnetic induction wireless charging device is aligned. When the user places the mobile terminal on the mobile terminal support plate of the wireless charging device including multiple transmitting coils, it cannot be ensured that the transmitting coil charging the mobile terminal is the transmitting coil with the highest charging efficiency, resulting in low charging efficiency and low power consumption. waste. It can be seen that the existing electromagnetic induction wireless charging technology has the problems of low charging efficiency or inconvenient charging operation.

在如图1所示的实现方式的基础上，还可以实现为如图4所示的实现方式。其中，在执行步骤106闭合第一发射线圈对应的开关之后，还可以执行步骤201至204：On the basis of the implementation shown in FIG. 1 , it can also be implemented as the implementation shown in FIG. 4 .

For another example, when the battery power of the mobile terminal is large, for example, the battery power has reached 95%, or the battery temperature is high, or the temperature of the receiving coil rises rapidly, a lower transmission power can be used to charge the mobile terminal.
在如图1所示的实现方式的基础上，还可以实现为如图5所示的实现方式。其中，在执行步骤106闭合第一发射线圈对应的开关之后，还可以执行步骤301：On the basis of the implementation shown in FIG. 1 , it can also be implemented as the implementation shown in FIG. 5 .

其中，闭合第二发射线圈对应的开关，继续为移动终端充电。Wherein, the switch corresponding to the second transmitting coil is closed to continue charging the mobile terminal.
当第一发射线圈的温度较高而不能继续为移动终端充电时，本申请实施例提供的无线充电方法，能够自动选择充电效率低于第一发射线圈，且高于其他发射线圈的第二发射线圈继续为移动终端充电，增强了无线充电的可靠性。When the temperature of the first transmitting coil is too high to continue charging the mobile terminal, the wireless charging method provided in the embodiment of the present application can automatically select the second transmitting coil whose charging efficiency is lower than that of the first transmitting coil and higher than that of other transmitting coils. The coil continues to charge the mobile terminal, enhancing the reliability of wireless charging.
在如图1、4、5和6中的任意一幅图所示的实现方式的基础上，还可以实现为如图7所示的实现方式。其中，在执行步骤106闭合第一发射线圈对应的开关之后，还可以执行步骤401和步骤402：On the basis of the implementation shown in any one of Figures 1, 4, 5 and 6, it can also be implemented as the implementation shown in Figure 7 .

值得说明的是，第三阈值和第四阈值可以由移动终端上电时自动设置，例如可以分别设置为70摄氏度和65摄氏度。当接收线圈的温度大于或等于第三阈值时，为避免移动终端的接收线圈损坏，断开为移动终端充电的发射线圈对应的开关，停止为移动终端充电。当移动终端的电池温度大于或等于第四阈值时，为避免移动终端的电池损坏，也需要断开为移动终端充电的发射线圈对应的开关，停止为移动终端充电。It is worth noting that the third threshold and the fourth threshold can be automatically set when the mobile terminal is powered on, for example, they can be set to 70 degrees Celsius and 65 degrees Celsius, respectively. When the temperature of the receiving coil is greater than or equal to the third threshold, in order to avoid damage to the receiving coil of the mobile terminal, turn off the switch corresponding to the transmitting coil for charging the mobile terminal, and stop charging the mobile terminal.
