具体而言，主电路板1上设有多个充电电路，多个电池2设在主电路板1上，每个电池2与相应的充电电路电连接。多个充电电路分别同时给多个电池2充电，可以减小充电电路的电压，延长电池2的寿命，同时还可以提高充电的速度。另外，多个电池2相比一个电池2与外界接触的面积增加，电池2上的热量可以很快的散去，进一步延长了电池2的寿命。
根据本发明实施例的移动终端100，通过在主电路板1上设置多个电池2和与多个电池2一一对应的多个充电电路，多个充电电路可以分别给多个电池2充电，不但可以提高充电速度，还可以减小充电电路的电压，延长电池2的寿命。另外，多个电池2与外界接触的面积增加，便于电池2的散热，进一步延长电池2的寿命。
在本发明的一些实施例中，如图1所示，主电路板1的上表面上设有凹槽11，多个电池2设在凹槽11内。多个充电电路设在主电路板1的下表面上，主电路板1上设有多个金属过孔，每个电池2通过相应的金属过孔与相应的充电电路电连接。由此，当电池2设在主电路板1上表面的凹槽11内时，一方面，凹槽11可以对电池2起到一定的固定作用，另一方面，金属过孔可以贯通主电路板1的下表面和凹槽11的底壁，减小金属过孔的长度，从而减小电池2的充电路径，降低发热量，延长电池2的寿命。
进一步地，多个充电电路位于凹槽11的正下方。由此，可以进一步地减小金属过孔的长度，从而减小电池2的充电路径，降低发热量，延长电池2的寿命。
可选地，充电电路为快充充电电路。需要说明的是，快充充电电路的充电电流大于2.5安培，充电电压为5V左右。由此可以提高电池2的充电速度，满足用户的使用需求。
在本发明的一些实施例中，如图1所示，多个电池2均匀分布。由此，便于充电电路的 布置，防止多个充电电路之间发生干涉。例如，在图1所示的示例中，主电路板1上设有九个电池2，九个电池2成三行三列的形式排布，由此便于九个充电电路的排布，防止九个充电电路在排布时发生干涉。
在本发明的一些实施例中，移动终端100还包括罩体，罩体与主电路板1限定出安装腔，电池2位于安装腔内。由此，可以将电池2固定在安装腔内，防止电池2与主电路板1脱离而造成电池2与充电电路断开，从而保证电池2充电的可靠性。
进一步地，罩体为一个且与主电路板1限定出一个安装腔，多个电池2均位于安装腔内。由此，可以简化主电路板1的结构及加工工艺，节约生产周期，降低生产成本。当然，本发明不限于此，罩体可以为多个且与主电路板1限定出多个安装腔，电池2位于相应的安装腔内。由此，便于每个电池2的固定。

如图1所示，根据本发明实施例的移动终端100，包括主电路板1和九个并联的电池2。其中主电路板1可以为PCB板。
具体地，主电路板1的上表面设有凹槽11，凹槽11位于主电路板1的中间位置，九个电池2成三行三列的形式设在凹槽11内。主电路板1的下表面设有九个充电电路，其中，充电电路为快充充电电路且位于凹槽11的正下方。需要说明的是，快充充电电路的充电电流大于2.5安培，充电电压为5V左右。由此可以加快充电的速度。九个电池2与九个充电电路一一对应，主电路板1上设有九个金属过孔，每个电池2通过相应的金属过孔与相应的充电电路连接。
由此，不但可以提高充电速度，还可以减小充电电路的电压，延长电池2的寿命。另外，多个电池2与外界接触的面积增加，便于电池2的散热，进一步延长电池2的寿命。
另外，主电路板1的边缘位置处设置有USB连接座3，USB连接座3通过主电路板1与九个充电电路连接，当USB连接座3与外界电源连接时，电流可以通过USB连接座3，到主电路板1，再到主电路板1上的九个充电电路，九个充电电路再通过金属过孔分别与九个电池2连接以为九个电池2充电。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或 多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
