具体的，如图3所示，电子设备可以包括至少一个处理器，可以执行下述电池加热方法：
S301、当电子设备连接充电设备时，至少一个处理器获取温度信息。
获取环境温度的触发条件包括但不限于：检测到电子设备连接充电设备，电池电压低于阈值，电池的充电电流低于阈值，和/或电池电量低于阈值等。
在亮屏充电状态下，用户会对电子设备进行操作，处理器负荷升高会让主板发热，从而通过导热部件对电池进行加热，所以此时可以不对电池进行加热。
在熄屏充电状态下，用户未对电子设备进行操作，处理器负荷最低以达到节能目的，所以主板升温不明显。如果此时环境温度过低，电池无法充电或充电缓慢，所以电池升温也不明显。可选在电子设备处于熄屏充电状态下获取温度信息。
可选的，电子设备中可以安装有第一温度传感器，第一温度传感器用于检测电子设备的温度信息。当电子设备连接充电设备时，至少一个处理器可以通过第一温度传感器获取电子设备的温度信息。
可选的，充电设备中可以安装有第二温度传感器，第二温度传感器用于检测充电设备的温度信息。当电子设备连接充电设备时，电子设备(至少一个处理器)可以与充电设备通信，获取充电设备的温度信息。
本申请所述的充电设备可以包括有线充电设备(例如电源适配器)和无线充电设备等。在有线充电设备通过通用串行总线(universal serial bus，USB)接口向电子设备充电时，电子设备可以通过USB接口从有线充电设备接收充电设备的温度信息。在无线充电设备通过电磁感应向电子设备的无线充电线圈供电时，电子设备可以通过电磁感应、蓝牙(Bluetooth)、近场通信(near field communication，NFC)等方式与无线充电设备进行通信，获取无线充电设备的温度信息。
S302、当温度信息低于预设阈值时，至少一个处理器为无线充电线圈提供第一电压信号，以使无线充电线圈的温度升高。
具体的，当充电设备的温度信息低于第一预设阈值，或者，电子设备的温度信息低于第二预设阈值时，至少一个处理器为无线充电线圈提供第一电压信号。充电设备的温度信息相当于电子设备的外部环境温度信息，即可以根据电子设备外部环境温度信息来决定是否加热电池。电子设备的温度信息表示电子设备的内部环境温度信息，即可以根据电子设备内部环境温度信息来决定是否加热电池。
至少一个处理器可以通过充电设备为无线充电线圈提供第一电压信号，即控制电压转换模块将充电设备的充电电压转换成为无线充电线圈加热的第一电压信号，使无线充电线圈发热，通过导热部件对电池进行加热。此时，无线充电线圈相当于电阻。
该第一电压信号可能为交流电或直流电。例如，在通过无线充电设备对电池进行充电时，无线充电线圈可以感应产生交流电。
第一电压信号的电平可以小于预设电平，第一电压信号的功率可以小于预设功率，第一电压信号的电流可以小于预设电流。预设电平可以指常温下通过无线充电线圈对电池充电时的额定电平，预设功率可以指常温下通过无线充电线圈对电池充电时的额定功率，预设电流可以指常温下通过无线充电线圈对电池充电时的额定电流。原因在于，电池温度较低时充电电流较小或无充电电流，如果通过无线充电线圈对电池充电时仍采用预设电平、预设电流或预设功率，产生的额外能量不能转换为电池中的储能将烧毁无线充电线圈。
示例性的，第一预设阈值或第二预设阈值可以为10℃。
另外，当温度信息低于预设阈值时，至少一个处理器还可以控制电子设备运行预设应用程序，当运行预设应用程序时，所述至少一个处理器的温度升高。
预设应用程序可以指：电子设备中预安装的至少一个应用程序，各应用程序占用处理器资源不同从而使得处理器发热量不同；或者，可以根据已安装软件的耗电历史记录确定预设应用程序，例如根据耗电历史记录中平均耗电量从高到低的顺序，从已安装软件中确定预设 应用程序。这些预设应用程序可以无显示界面或音视频输出，从而使得用户无感知。
运行预设应用程序的方式包括但不限于：打开“允许软件后台运行”开关，使得预设应用程序可以在后台可以运行；根据不同的温度信息确定预设应用程序的运行顺序，例如在温度信息的值较低时运行发热量大的预设应用程序，在温度信息的值较高时运行发热量小的预设应用程序。
S303、导热部件将无线充电线圈的热量传递给电池。
导热部件至少可以包括石墨片、前壳组件等，导热部件与电池和无线充电线圈贴合。导热部件用于在无线充电线圈与电池之间进行热传递，从而将无线充电线圈的热量传递给电池。
可选的，导热部件还可以与电池和至少一个处理器所在区域贴合。在至少一个处理器通过运行预设应用程序使得自身温度升高时，导热部件还用于将所述至少一个处理器的热量传递给电池。
由于至少一个处理器位于主板上，处理器温度升高也会让主板温度升高，由于导热部件还可以与主板贴合(例如，主板及电池均固定于前壳组件上，或者，石墨片的贴合范围从电池延伸至主板)，导热部件可以与电池和至少一个处理器所在区域贴合。所以可以通过从主板、导热部件至电池之间的热传导来对电池进行加热。
需要说明的是，以上两种加热方式可以同时采用，以提高加热速度。

可选的，电子设备中还可以包括第二温度传感器，第二温度传感器用于测量电池的温度信息。
如图4所示，该电池加热方法还可以包括：
S401、当电池的温度信息大于或等于第一电池温度门限时，至少一个处理器控制电压转换模块通过充电设备向电池充电，停止为无线充电线圈提供第一电压信号。
可选的，当电池的温度信息大于或等于第一电池温度门限时，至少一个处理器停止运行预设应用程序或者停止运行部分所述预设应用程序。
当电池的温度信息大于或等于第一电池温度门限时，电池活性提高，电池可以正常充电，此时可以通过以上方式停止对电池进行加热。
可选的，当电池的温度信息大于或等于第一电池温度门限时，电池活性提高，可以提高对电池的充电电流，以提高充电速度。提高对电池的充电电流也可以称为大电流充电、超级快充、闪充、快充等，本申请不作限定。

S402、当电池的温度大于或等于第二电池温度门限或者亮屏时，至少一个处理器控制电压转换模块降低对电池的充电电流。
