需要说明的是，本申请实施例的主要思想在于：在电子设备中新增一柔性电路板，该柔性电路板可以与电池接触，在充电状态下，在电池的温度低于预设阈值时，可以通过加热该柔性电路板来提高电池的温度，从而提高电池的充电速度，这样，即便在外界温度较低，也可以满足对电子设备进行快速充电和开机等技术需求。
本申请实施例可以适用于移动个人计算机、平板电脑、智能手表、增强现实(Augmented Reality，AR)设备、虚拟现实技术(Virtual Reality，VR)设备、电动汽车、电动自行车、电动牙刷等电子设备中。

图1所示的电子设备，在对电池充电时，可以由外界电源可插拔提供电源，其中，为了对电池进行快速充电，充电接口模块可以通过外接快充头与外界电源连接，外接快充头具体可以为电池提供11V以上的充电电压。
在外界电源提供电源的情况下，充电接口模块可以通过第一电路板对电池充电。其中，在电池温度较低的情况下(比如低于预设阈值)，为了避免因电池的温度较低而出现充电速度慢的问题，充电接口模块可以对加热元件供电，加热元件在供电的情况下，可以对电池加热，以升高电池的温度，进而可以加快充电速度。
这样，由于在电子设备中增加了加热元件，因此，在对电池进行充电时，在电池温度较低的情况下，充电接口模块一方面可以对电池进行充电，另一方面可以为加热元件供电，以对电池迅速加热，从而升高电池的温度，使得电池的充电速度不会因低温而受到影响，进而提高电池的充电速度。

可选地，加热元件可以通过板对板连接器与充电接口模块连接，这样，可以安全迅速地将加热元件加热到所需的温度，从而升高电池的温度，此外， 针对第一电路板而言，第一电路板也可以通过板对板连接器与充电接口模块连接。

本申请实施例还提供了一种基于上述电子设备的充电方法，其中，图8是本申请的一个实施例充电方法的流程示意图。所述方法如下所述。
S802：在通过第一电路板对电池充电的情况下，获取所述电池的温度。
在S802中，在通过第一电路板对电子设备中的电池进行充电时，可以获取电池的温度。
具体地，在将电子设备与外接电源连接时，可以视为对电子设备的电池进行充电，此时，电子设备可以通过图1所示实施例中的温度传感器获取电池的温度。
需要说明的是，在对电池充电时，电子设备内部的加热元件默认处于对的电池的非加热状态，也就是说，S802中，在获取电池的温度时，加热元件 处于非供电状态。
S804：在温度小于预设阈值，且加热元件的加热时长小于第一预设时长的情况下，为所述加热元件供电，所述加热元件加热所述电池。
在S804中，在获取到电池的温度后，可以判断电池的温度是否小于预设阈值(可以根据实际情况设定)，若小于，则可以对加热元件供电，以便加热元件对电池进行加热。
在对电池加热时，可以对加热时长进行计时，并判断电池的温度(加热过程中的温度)是否小于预设阈值，且加热时长是否小于第一预设时长，若温度小于预设阈值，且加热时长小于第一预设时长，则可以继续加热，以便继续升高电池的温度，反之则可以执行S806。
S806：在所述温度大于预设阈值，或所述加热元件的加热时长大于或等于第一预设时长的情况下，停止为所述加热元件供电。
在S806中，在电池的温度被加热到大于预设阈值的情况下，可以停止对加热元件供电，即停止对电池加热，或者，在加热时长大于或等于第一预设时长的情况下，为了防止温度传感器因长时间处于高温状态而失效，也可以停止为加热元件供电。
需要说明的是，在对电池充电的过程中，为了防止加热元件反复启停，从而影响加热元件的使用寿命，在停止为加热元件供电之后，也可以开始计时，在计时时长等于第二预设时长时，可以再次获取电池的温度，基于获取的温度，确定是否对加热元件供电。也就是说，在停止为加热元件供电之后，可以间隔第二预设时长再获取电池的温度，基于再次获取到的温度确定是否需要为加热元件供电。
还需要说明的是，在电池的温度大于或等于预设阈值的情况下，由于不需要为加热元件供电，因此，在这种情况下可以以较大的第一充电电流为电池进行充电，从而可以提升电池的充电速度。此外，由于在电池的温度小于预设阈值的情况下，需要同时为电池充电以及对电池加热，因此，在这种情 况下可以以较小的第二充电电流电流为电池进行充电，其中，第一充电电流大于第二充电电流。
为了更清楚地描述上述电子设备的充电方法，还可以参见图9，图9是本申请的一个实施例充电方法的流程示意图。
S901：在通过第一电路板对电池充电的情况下，获取电池的温度。
需要说明的是，这里的执行S901的前提是加热元件处于非供电状态，即电池处于非加热状态。
其中，在加热元件处于非供电状态时，由于不需要为加热元件供电，即不需要对电池加热，因此，在这种情况下可以以较大的第一充电电流为电池进行充电，从而可以提升电池的充电速度。
S902：判断电池的温度是否小于预设阈值。
若是，则可以执行S903；若否，则可以执行S901。
S903：对加热元件进行供电。
其中，由于在电池的温度小于预设阈值的情况下，需要同时为电池充电以及对电池加热，因此，在这种情况下可以以较小的第二充电电流电流为电池进行充电，第一充电电流大于第二充电电流。
S904：判断电池的温度是否小于预设阈值，且加热时长是否小于第一预设时长。
若是，则可以执行S903；若否，则可以执行S905。
S905：对加热元件停止供电。
S906：判断停止加热时长是否等于第二预设时长。
在对加热元件停止供电之后可以开始计时，并判断计时时长是否等于第二预设时长。
若是，则可以执行S901；若否，则可以继续执行S906。
本申请实施例提供的电子设备包括第一电路板，加热元件和充电接口模块，其中，充电接口模块的输入端可与外界电源可插拔连接，充电接口模块 的输出端与第一电路板的输入端电连接，第一电路板的输出端与电池电连接，第一电路板对电池充电，充电接口模块的输出端与加热元件电连接，加热元件对电池加热。这样，由于在电子设备中增加了加热元件，在电池温度较低时，加热元件可以对电池加热，以升高电池的温度，因此，可以使得电池的充电速度不会因低温而受到影响，进而提高电池的充电速度。
需要说明的是，本申请实施例提供的充电方法，执行主体可以为充电装置，或者该充电装置中的用于执行加载充电方法的充电接口模块。本申请实施例中以充电装置执行加载充电方法为例，说明本申请实施例提供的充电方法。

可选的，本申请实施例还提供一种电子设备，包括处理器1110，存储器1109，存储在存储器1109上并可在所述处理器1110上运行的程序或指令，该程序或指令被处理器1110执行时实现上述充电方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
需要注意的是，本申请实施例中的电子设备包括上述所述的移动电子设备和非移动电子设备。
图11为实现本申请实施例的一种电子设备的硬件结构示意图。
该电子设备1100包括但不限于：射频单元1101、网络模块1102、音频 输出单元1103、输入单元1104、传感器1105、显示单元1106、用户输入单元1107、接口单元1108、存储器1109、以及处理器1110等部件。
本领域技术人员可以理解，电子设备1100还可以包括给各个部件供电的电源(比如电池)，电源可以通过电源管理系统与处理器1110逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。图11中示出的电子设备结构并不构成对电子设备的限定，电子设备可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置，在此不再赘述。
其中，处理器1110，用于在通过所述第一电路板对电池充电的情况下，获取所述电池的温度；在所述温度小于预设阈值，且所述加热元件的加热时长小于第一预设时长的情况下，为所述加热元件供电，所述加热元件加热所述电池；在所述温度大于预设阈值，或所述加热元件的加热时长大于或等于第一预设时长的情况下，停止为所述加热元件供电。
这样，由于在电子设备中增加了加热元件，因此，在对电池进行充电时，在电池温度较低的情况下，充电接口模块一方面可以对电池进行充电，另一方面可以为加热元件供电，以对电池迅速加热，从而升高电池的温度，使得电池的充电速度不会因低温而受到影响，进而提高电池的充电速度。
可选的，处理器1110，还用于若所述温度大于或等于所述预设阈值，则基于第一充电电流对所述电池充电，所述第一充电电流大于第二充电电流，所述第二充电电流为所述加热元件加热所述电池的情况下所述电池的充电电流。
本申请实施例还提供一种可读存储介质，所述可读存储介质上存储有程序或指令，该程序或指令被处理器执行时实现上述充电方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
其中，所述处理器为上述实施例中所述的电子设备中的处理器。所述可读存储介质，包括计算机可读存储介质，如计算机只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁 碟或者光盘等。
本申请实施例另提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行程序或指令，实现上述充电方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。
应理解，本申请实施例提到的芯片还可以称为系统级芯片、系统芯片、芯片系统或片上系统芯片等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本申请各个实施例所述的方法。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上 述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
