Specifically, as shown in fig. 3, the electronic device may include at least one processor, and may perform the following battery heating method:

s301, when the electronic device is connected with the charging device, the at least one processor acquires temperature information.

Triggering conditions for obtaining ambient temperature include, but are not limited to: detecting that the electronic device is connected with a charging device, the voltage of the battery is lower than a threshold value, the charging current of the battery is lower than a threshold value, and/or the electric quantity of the battery is lower than a threshold value, etc.

Under bright screen charged state, the user can operate electronic equipment, and the treater load risees and can let the mainboard generate heat to heat the battery through heat-conducting component, so can not heat the battery this moment.

In the screen-off charging state, the user does not operate the electronic equipment, and the load of the processor is lowest to achieve the purpose of energy conservation, so that the temperature rise of the mainboard is not obvious. If the ambient temperature is too low, the battery cannot be charged or is slowly charged, so that the temperature rise of the battery is not obvious. Optionally, the temperature information is obtained when the electronic device is in a screen-off charging state.

Optionally, a first temperature sensor may be installed in the electronic device, and the first temperature sensor is configured to detect temperature information of the electronic device. When the electronic device is connected with the charging device, the at least one processor can acquire the temperature information of the electronic device through the first temperature sensor.

Optionally, a second temperature sensor may be installed in the charging device, and the second temperature sensor is configured to detect temperature information of the charging device. When the electronic device is connected to the charging device, the electronic device (at least one processor) may communicate with the charging device to obtain temperature information of the charging device.

The charging device described herein may include a wired charging device (e.g., a power adapter), a wireless charging device, and the like. When the wired charging device charges the electronic device through a Universal Serial Bus (USB) interface, the electronic device may receive temperature information of the charging device from the wired charging device through the USB interface. When the wireless charging device supplies power to the wireless charging coil of the electronic device through electromagnetic induction, the electronic device can communicate with the wireless charging device through modes such as electromagnetic induction, Bluetooth (Bluetooth), Near Field Communication (NFC), and the like, so as to acquire temperature information of the wireless charging device.

S302, when the temperature information is lower than a preset threshold value, at least one processor provides a first voltage signal for the wireless charging coil, so that the temperature of the wireless charging coil is increased.

Specifically, when the temperature information of the charging device is lower than a first preset threshold value, or the temperature information of the electronic device is lower than a second preset threshold value, the at least one processor provides a first voltage signal for the wireless charging coil. The temperature information of the charging device corresponds to the external environment temperature information of the electronic device, and whether to heat the battery can be determined according to the external environment temperature information of the electronic device. The temperature information of the electronic device indicates the internal environment temperature information of the electronic device, and whether to heat the battery may be determined based on the internal environment temperature information of the electronic device.

At least one treater can provide first voltage signal for wireless charging coil through battery charging outfit, and control voltage conversion module converts the first voltage signal of wireless charging coil heating into with battery charging outfit's charging voltage conversion promptly, makes wireless charging coil generate heat, heats the battery through heat-conducting component. In this case, the wireless charging coil corresponds to a resistor.

The first voltage signal may be an alternating current or a direct current. For example, the wireless charging coil may induce an alternating current when the battery is charged by the wireless charging device.

The level of the first voltage signal may be less than a preset level, the power of the first voltage signal may be less than a preset power, and the current of the first voltage signal may be less than a preset current. The preset level can refer to the rated level when the battery is charged through the wireless charging coil at normal temperature, the preset power can refer to the rated power when the battery is charged through the wireless charging coil at normal temperature, and the preset current can refer to the rated current when the battery is charged through the wireless charging coil at normal temperature. The reason is that the charging current is low or no charging current when the temperature of the battery is low, if the battery is charged by the wireless charging coil, the wireless charging coil is still charged by adopting a preset level, preset current or preset power, and the generated extra energy cannot be converted into energy storage in the battery to burn out the wireless charging coil.

For example, the first preset threshold or the second preset threshold may be 10 ℃.

In addition, when the temperature information is lower than the preset threshold value, the at least one processor can also control the electronic device to run a preset application program, and when the preset application program is run, the temperature of the at least one processor is increased.

The preset application may refer to: the method comprises the steps that at least one application program is preinstalled in the electronic equipment, and the application programs occupy different processor resources so that the processors generate different heat; alternatively, the preset application may be determined from the power consumption history of the installed software, for example, the preset application may be determined from the installed software according to the order of the average power consumption from high to low in the power consumption history. These preset applications may have no display interface or audio-visual output, making the user imperceptible.

The way to run the preset application includes but is not limited to: turning on a switch for allowing the software to run in the background so that the preset application program can run in the background; the operation sequence of the preset application programs is determined according to different temperature information, for example, the preset application program with large heating value is operated when the value of the temperature information is low, and the preset application program with small heating value is operated when the value of the temperature information is high.

And S303, the heat conducting component transfers the heat of the wireless charging coil to the battery.

The heat conducting component can at least comprise a graphite sheet, a front shell assembly and the like, and is attached to the battery and the wireless charging coil. The heat conducting component is used for conducting heat transfer between the wireless charging coil and the battery, and therefore heat of the wireless charging coil is transferred to the battery.

Optionally, the thermally conductive member may also be attached to the area where the battery and the at least one processor are located. The heat conducting component is also used for transferring heat of the at least one processor to the battery when the temperature of the at least one processor is increased by running a preset application program.

Because at least one treater is located the mainboard, the treater temperature risees and also can let the mainboard temperature rise, because heat-conducting component can also laminate with the mainboard (for example, mainboard and battery all are fixed in before on the shell subassembly, perhaps, the laminating scope of graphite flake extends to the mainboard from the battery), heat-conducting component can laminate with battery and at least one treater place region. The battery can be heated by heat conduction from the main board, the heat conductive member to the battery.

It should be noted that the above two heating methods can be simultaneously adopted to increase the heating speed.

According to the electronic equipment and the battery heating method provided by the embodiment of the application, when the electronic equipment is connected with the charging equipment, at least one processor is used for acquiring temperature information; when the temperature information is lower than a preset threshold value, the at least one processor provides a first voltage signal for the wireless charging coil so as to increase the temperature of the wireless charging coil; the heat conducting component is used for transferring heat of the wireless charging coil to the battery. The battery is heated by utilizing the existing parts in the electronic equipment, so that a user does not need to additionally configure a heating source, the cost is saved, and the user experience is improved.

Optionally, the electronic device may further include a second temperature sensor, where the second temperature sensor is configured to measure temperature information of the battery.

As shown in fig. 4, the battery heating method may further include:

s401, when the temperature information of the battery is larger than or equal to a first battery temperature threshold, at least one processor controls the voltage conversion module to charge the battery through the charging device, and the first voltage signal is stopped being provided for the wireless charging coil.

Optionally, when the temperature information of the battery is greater than or equal to the first battery temperature threshold, the at least one processor stops running the preset application program or stops running a part of the preset application program.

When the temperature information of the battery is greater than or equal to the first battery temperature threshold, the battery activity is improved, the battery can be normally charged, and at the moment, the heating of the battery can be stopped in the above mode.

Optionally, when the temperature information of the battery is greater than or equal to the first battery temperature threshold, the battery activity is increased, and the charging current to the battery may be increased to increase the charging speed. Increasing the charging current to the battery may also be referred to as high current charging, super fast charging, flash charging, fast charging, etc., and the application is not limited.

An exemplary first battery temperature threshold may be 10 ℃.

S402, when the temperature of the battery is larger than or equal to a second battery temperature threshold or the screen is on, the at least one processor controls the voltage conversion module to reduce the charging current of the battery.

The third predetermined threshold is greater than the second predetermined threshold, which may be 30 degrees celsius, for example.

Reducing the charging current to the battery may refer to exiting the high current charging mode and returning to the normal charging mode. The step has the function of preventing the battery from being overheated, so that the electronic equipment is hot, and the use experience of a user is influenced.

Based on the foregoing discussion, in particular, an embodiment of the present application provides an electronic device, including: at least one processor, a thermally conductive member, a wireless charging coil, a battery, a first temperature sensor.
