移动终端可以包括充电电路板、主控电路板、电池保护电路板，以下对上述三种电路板进行简单说明。
充电电路板：指设有充电接口的电路板，该充电接口用于与外部充电器连接，该充电接口电路板还可以有其他电路模块，如音频模块、马达模块、天线模块等。
主控电路板：主控电路板又称主板、主机板、系统板、逻辑板、母板、底板等，可以包括充电管理芯片以及放电接口等。
电池保护电路板：电池保护电路板是针对可充电(如锂电池)起保护作用的集成电路板，包括控制IC(Integrated Circuit，集成电路)、MOS开关(Metal-Oxide-Semiconductor，即金属-氧化物-半导体)、电阻及辅助器件NTC(Negative temperature coefficient，即负温度系数)、ID存储器(单线接口存储器，ID为Identification的缩写)以及PCB(Printed Circuit Board，印制电路板)等。在正常充放电情况下，控制IC控制MOS开关导通，使电芯(即去掉电池保护电路板的电池)与外电路导通；当电芯电压或回路电流超过规定值时，控制IC控制MOS开关截止，保护电芯的安全。
此外，移动终端还可以包括：RF(Radio Frequency，射频)电路、存储器、其他输入设备、显示屏、传感器、I/O子系统、处理器、电源管理芯片、摄像头、蓝牙模块、虚拟按键、实体按键等部件，在此不再赘述。

本领域技术人员可以理解，上述移动终端的结构并不构成对电子设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。本领领域技术人员可以理解显示屏属于用户界面(UI，User Interface)，且手机可以包括比图示或者更少的用户界面。
移动终端在工作过程中，电池组件会为以上部件进行供电。
在以下实施例中，电子设备可以以手机为例，随着手机功能日益提高，内部器件复杂度不断提高，对电池的架构和供电能力尤为重要。当然，本申请实施例的电子设备并不限于手机。
手机的充电方式包括大电流充电和小电流充电，对于不同的电池，大电流充电的电流范围、小电流充电的电流范围均不同，例如电池的标准充电电流为0.1C(C指电池的容量)，大电流充电的电流范围为0.3C～0.4C，小电流充电的电流小于0.1C。
图1为一种手机拆掉后盖的结构示意图。
参照图1，手机包括沿图中上下方向依次排列的充电接口电路板01、电池02、电池保护电路板03以及主控电路板04，充电接口电路板01上分别设有充电接口011和 第一连接器012，主控电路板04上设置有第二连接器041和第三连接器042，第一连接器012和第二连接器041通过第一导线05连接；第三连接器042与电池保护电路板03通过第二导线06连接，电池保护电路板03与电池02电连接。本方案在进行大电流充电过程中，电流依次经充电接口011、充电接口电路板01、第一连接器012、第一导线05、第二连接器041、第二连接器041和第三连接器042的连接电路、第三连接器042、第二导线06、电池保护电路板03进入电池02。申请人发现该方案因大电流充电过程需经过主控电路板04上的第二连接器041和第三连接器042，申请人发现在大电流充电过程中，第二连接器041和第三连接器042会产生较大的阻抗，导致手机的大电流充电路径中充电阻抗较大，并且大电流电路产生较多的热量。
为解决上述问题，本申请实施例提供了一种手机的结构设计方案，如图2～3所示。图2为本申请实施例手机的前视图；图3为本申请实施例手机拆掉后盖的结构示意图。
参照图2～3，本申请实施例的手机100包括充电接口电路板1、电池2、电池保护电路板3以及主控电路板4。电池2与电池保护电路板3电连接，充电接口电路板1与主控电路板4电连接。充电接口电路板1、电池2和主控电路板4沿第一方向P依次排列，电池2与电池保护电路板3沿第二方向排列，第二方向与第一方向P垂直，且电池保护电路板3的第一端31与充电接口电路板1电连接，电池保护电路板3的第二端32与主控电路板4电连接。其中，充电接口电路板1上设置有充电接口11(图3中充电接口处的箭头指外部充电器与充电接口的连接方向)，充电接口11用于与外部充电器连接进行充电，主控电路板4包括充电管理芯片(图中未示出)，充电管理芯片用于控制充电过程，例如可根据电池2的电压值选择充电路径。具体地，可选择充电接口电路板1与主控电路板4之间的充电路径，或选择充电接口电路板1与电池保护电路板3之间的充电路径。
本申请实施例提供的手机100，在大电流充电过程中，电流经充电接口电路板1、将电池保护电路板3的第一端31与充电接口电路板1电连接的连接线、电池保护电路板3，最后进入电池2。相较于上述现有技术，由于充电接口电路板1与电池保护电路板3电连接，大电流充电通路不需经过主控电路板4上的连接器，降低了大电流通路中的阻抗，从而降低了手机100充电过程中所产生的热量。
可选地，电池保护电路板3可横向放置，电池保护电路板3可设置于充电接口电路板1沿第二方向的外侧、和/或主控电路板4沿第二方向的外侧，电池2的体积不变，因此，电池2的容量仍较大。
可选地，因原有第一方向P的电池保护电路板3的空间被空出，本申请实施例通过增大电池2沿第一方向P的长度，并将电池2沿第二方向的宽度缩短，从而保证电池的容量基本不变，且电池保护电路板3在第二方向上提供容纳空间，使电池保护电路板3设置于充电接口电路板1与主控电路板4之间，并且电池保护电路板3沿第一方向P的第一端31靠近充电接口电路板1设置，且相应地，电池保护电路板3沿第一方向P的第二端32靠近主控电路板4设置，如图3～4所示，手机100的结构紧凑，体积较小。并且因电池保护电路板3的第一端31靠近充电接口电路板1，使得将电池保护电路板3的第一端31与充电接口电路板1电连接的连接线可采用较短的导线，缩短了大电流充电电路中电路板间连接线的长度，从而进一步降低了大电流通路中的阻抗， 从而降低充电过程中产生的热量；同理，电池保护电路板3的第二端32与主控电路板4之间也可采用较短的导线，使小电流通路中的电路板间连接线也较短。
图4为本申请实施例手机中电池与电池保护电路板沿手机厚度方向设置的结构示意图。
需要说明的是：上述的第二方向可以是手机100的宽度方向(即图3所示的第二方向M)，也可使手机100的厚度方向(即图4所示的第二方向M′)。对于图4所示的结构方案，为了不增加手机的整体厚度，可将电池2设计为异形电池，在电池2上预留电池保护电路板3的安装结构，如该安装结构可为缺口或凹槽。
上述的电池保护电路板3可采用方形、长条状结构等。因通常手机、平板电脑等电子设备中的电池均为长方形，采用长条状结构的电池保护电路板3，并将电池保护电路板3的长度方向与第一方向P平行，如图3所示，电池保护电路板3沿第二方向占用的空间较小，可使手机100的结构紧凑、体积较小。
上述的充电接口电路板1、主控电路板4分别与电池保护电路板3电连接，可将一根导线的两端分别焊接于电池保护电路板3的第一端31与充电接口电路板1，另一根导线的两端分别焊接于电池保护电路板3的第二端32与主控电路板4；也可在设计充电接口电路板1和主控电路板4时，使充电接口电路板1包括第一连接器12，主控电路板4包括第二连接器41，再通过第一导线5将电池保护电路板3的第一端31与第一连接器12连接。相应地，通过第二导线6将电池保护电路板3的第二端32与第二连接器41连接。在流水化组装手机100时，通过第一连接器12和第二连接器41可以快速将电池保护电路板3分别与充电接口电路板1、主控电路板4插接，使得手机100的组装操作较便捷、快速。
需要说明的是：因电池保护电路板3沿第一方向P的第一端31靠近充电接口电路板1设置，第一导线5的长度为10～15mm；相应地，电池保护电路板3沿第一方向P的第二端32靠近主控电路板4设置，第二导线6的长度为10～15mm。
可选地，第一连接器12和第二连接器41均可采用BTB连接器(Board To Board，板对板连接器)，BTB连接器的引脚间距和高度较小，有利于缩小手机100的体积。以第二连接器41为例，将第二连接器41的母座焊接在主控电路板4上，公座焊接在电池保护电路板3的第二端32引出的第二导线6上。
需要说明的是：当电流经充电接口电路板1的充电接口11、充电接口电路板1、主控电路板4中的充电管理芯片、第二连接器41、第二导线6进入电池保护电路板3，最后进入电池2，实现了手机100的小电流充电流程。而当手机100需要放电时，电池2内的电流经电池保护电路板3、电池保护电路板3与主控电路板4之间的第二导线6，最后送入主控电路板4中需要供电的模块。
手机100中第一导线5采用充电连接线，用于实现充电接口电路板1与电池保护电路板3的电连接，以连通手机100的大电流充电电路。可选地，第二导线6包括一条充电连接线和一条放电连接线，或者第二导线6为一条充放电连接线。图3中第二导线6为充放电连接线，手机100中电池保护电路板3与主控电路板4之间的连接线路较简单。
在手机100中电池2、电池保护电路板3、第一导线5以及第二导线6均同时使用， 因此，本申请实施例中电池2、电池保护电路板3、第一导线5以及第二导线6形成整体的装配单元，以缩短手机100的组装流程，提高装配效率。
需要注意的是：电池2与电池保护电路板3的电连接方式为焊接，具体为：将电池2上的金属箔片与电池保护电路板3上的金属箔片通过激光焊接在一起。可选地，第一导线5以及第二导线6与电池保护电路板3的结合方式为：取一根长的FPC排线(Flexible Printed Circuit，柔性电路板)，该FPC排线的长度大于电池保护电路板3沿第一方向P的长度，将该FPC排线的中部沿第一方向P嵌入电池保护电路板3中，且FPC排线的两端延伸至电池保护电路板3的第一端31和第二端32的外侧，以形成第一导线5和第二导线6，制作工艺较简单。
上述充电接口电路板1与主控电路板4的电连接方式为：将一根导线的两端分别与充电接口电路板1、主控电路板4焊接。可选地，还可通过传输组件将充电接口电路板1与主控电路板4电连接，该传输组件包括第三连接器13、第四连接器42以及连接于第三连接器13与第四连接器42的第三导线7，第三连接器13设置于充电接口电路板1上，第四连接器42设置于主控电路板4上，可快速将充电接口电路板1与主控电路板4插接，简化手机100的组装操作，提高生产效率。
其中，第三连接器13和第四连接器42也可采用BTB连接器，便于缩小手机100的体积。
进一步地，本申请实施例手机100的小电流充电通路为：电流经充电接口电路板1的充电接口11、第三连接器13、充电接口电路板1和主控电路板4之间的第三导线7、第四连接器42进入主控电路板4的充电管理芯片，再经第二连接器41、主控电路板4与电池保护电路板3之间的第二导线6进入电池保护电路板3，最后进入电池2。
此外，充电接口电路板1与主控电路板4之间的其他通信也可采用第三导线7，简化手机100中电路板间的连线线路，方便接线。
可选地，本申请实施例中充电接口电路板1包括第一充电支路和第二充电支路，其中，第一充电支路将充电接口11与第一连接器12连接，第二充电支路将充电接口11与第三连接器13连接，在第一充电支路和第二充电支路连接有切换开关，该切换开关与充电管理芯片电连接，且该切换开关可切换第一充电支路和第二充电支路的通断。当充电管理芯片控制切换开关将第一充电支路连通、第二充电支路断开时，手机100采用大电流充电通路进行充电；当充电管理芯片控制切换开关将第二充电支路连通、第一充电支路断开时，手机100采用小电流充电通路进行充电，充电方式灵活，用户可根据不同的使用需要选择合适的充电方式,控制切换大电流充电通路与小电流充电通路的通断较简单。
当将外接电源与充电接口11连通时，即可为手机100进行充电。具体的充电流程为：判断电池内的电压；当电池2内电压小于第一预设值时，进入预充电模式，充电管理芯片通过充电接口电路板1上Sensor Hub/AP(Sensor Hub/Application processor，传感器中心协处理器/应用处理器)控制充电接口电路板1上的单刀双掷开关将第二充电支路接通，电流经第三连接器13、第三导线7、第四连接器42进入充电管理芯片，再经第二连接器41、第二导线6进入电池保护电路板3，最后进入电池2，实现电池的小电流充电；当电池2内的电压达到上述的第一预设值时，进入恒流充电模式，单 刀双掷开关将第一充电支路接通，电流经第一连接器12、第一导线5、电池保护板3后进入电池2，实现电池的大电流充电；当电池2内的电压达到第二预设值时，进入恒压充电模式，Sensor Hub/AP控制单刀双掷开关将第二充电支路接通，再次进行小电流充电，直至充满。在电池不同的电压值下，采用不同的充电方式，可保护电池，延长电池的使用寿命。
可选地，第一导线5、第二导线6和第三导线7可采用导线束，成本低；第一导线5、第二导线6和第三导线7也可采用柔性电路板，柔性电路板具有配线密度高、重量轻、厚度薄的特点，缩小手机100的重量和体积，且使电路板间的接线较简单，有利于手机100的小型化。

本申请实施例提供的电池组件可安装于电子设备内，当电子设备进行大电流充电时，电流经充电接口电路板1、将电池保护电路板3的第一端31与充电接口电路板1电连接的连接线、电池保护电路板3，最后进入电池2。相较于现有技术，由于充电接口电路板1与电池保护电路板3电连接，大电流充电通路不需经过主控电路板4上的连接器，降低了大电流通路中的阻抗，从而降低了电池组件充电过程中产生的热量。
当电池组件安装于电子设备内时，电池保护电路板3可横向放置，电池保护电路板3可位于充电接口电路板1沿第二方向的外侧，和/或主控电路板4沿第二方向的外侧，电池2的体积可保持不变，因此，电池2的容量仍较大。
可选地，当电池组件安装于电子设备内时，因原有第一方向P的电池保护电路板3的空间被空出，上述电池组件通过增大电池2沿第一方向P的长度，并将电池2沿第二方向的宽度缩短，从而保证电池2的容量基本不变，且电池保护电路板3在第二方向上提供容纳空间，电池保护电路板3沿第一方向P的第一端31靠近充电接口电路板1设置，电池保护电路板3沿第一方向P的第二端32靠近主控电路板4设置，电池保护电路板3可位于充电接口电路板1和主控电路板4之间。电池组件的结构紧凑，体积较小。因电池保护电路板3的第一端31靠近充电接口电路板1，使得将电池保护电路板3的第一端31与充电接口电路板1电连接的连接线可采用较短的导线，缩短了大电流充电电路中电路板间连接线的长度，从而进一步降低了大电流通路中的阻抗，从而降低充电过程中所产生的热量；同理，电池保护电路板3的第二端32与主控电路板4之间也可采用较短的导线，使小电流通路中的电路板间连接线也较短。
需要注意的是：上述的第二方向可以是电子设备的宽度方向(即图3所示的第二方向M)，也可使电子设备的厚度方向(即图4所示的第二方向M′)。对于图4所示的电池组件设计方案，将电池2设计为异形电池，在电池2上预留电池保护电路板3的安装结构，如该安装结构可为缺口或凹槽。
上述的电池保护电路板3可采用方形、长条状结构等。因通常手机、平板电脑等 移动电子设备中的电池2均为长方形，采用长条状结构的电池保护电路板3，并将电池保护电路板3的长度方向与第一方向P平行，如图3所示，电池保护电路板3沿第二方向占用的空间较小，可使应用该电池组件的电子设备结构紧凑、体积较小。
上述的充电接口电路板1、主控电路板4分别与电池保护电路板3电连接，可将一根导线的两端分别焊接于电池保护电路板3的第一端31与充电接口电路板1，另一根导线的两端分别焊接于电池保护电路板3的第二端32与主控电路板4。可选地，在设计充电接口电路板1和主控电路板4时，使充电接口电路板1包括第一连接器12，主控电路板4包括第二连接器41，电池组件还包括连接于电池保护电路板3的第一端31的第一导线5，以及连接于电池保护电路板3的第二端32的第二导线6，再通过第一导线5将电池保护电路板3的第一端31与第一连接器12连接。相应地，通过第二导线6将电池保护电路板3的第二端32与第二连接器41连接。在流水化组装电子设备时，通过第一连接器12和第二连接器41可以快速将电池保护电路板3分别与充电接口电路板1、主控电路板4插接，使得电子设备的组装操作较便捷、快速。
需要说明的是：因电池保护电路板3沿第一方向P的第一端31靠近充电接口电路板1设置，第一导线5的长度为10～15mm；相应地，电池保护电路板3沿第一方向P的第二端32靠近主控电路板4设置，第二导线6的长度为10～15mm。
电池组件中第一导线5采用充电连接线，用于实现充电接口电路板1与电池保护电路板3的电连接，以连通应用该电池组件的电子设备的大电流充电电路。可选地，第二导线6包括一条充电连接线和一条放电连接线，或者第二导线6为一条充放电连接线。图3中第二导线6为充放电连接线，电池保护电路板3与主控电路板4之间的连接线路较简单。
在电池组件中的电池2、电池保护电路板3、第一导线5以及第二导线6均同时使用，因此，本申请实施例中电池2、电池保护电路板3、第一导线5以及第二导线6形成整体的装配单元。如此，在将电池组件安装于电子设备内时，可缩短该电子设备的组装流程。
需要说明的是：电池2与电池保护电路板3的电连接方式为焊接，具体为将电池2上的金属箔片与电池保护电路板3上的金属箔片通过激光焊接在一起。
第一导线5和第二导线6可采用导线束，成本低；第一导线5和第二导线6也可采用柔性电路板，柔性电路板具有配线密度高、重量轻、厚度薄的特点，有利于电子设备的小型化。
可选地，第一导线5以及第二导线6与电池保护电路板3的结合方式为：取一根长的FPC排线(Flexible Printed Circuit，柔性电路板)，该FPC排线的长度大于电池保护电路板3沿第一方向P的长度，将该FPC排线的中部沿第一方向P嵌入电池保护电路板3中，且FPC排线的两端延伸至电池保护电路板3的第一端31和第二端32的外侧，以形成第一导线5和第二导线6，制作工艺较简单。
实施例3
本申请实施例包括一种手机，包括充电接口电路板1、电池2、电池保护电路板3和主控电路板4，电池2与电池保护电路板3电连接，充电接口电路板1包括充电接口11，充电接口电路板1、电池2和主控电路板4沿手机的长度方向依次排列，电池 保护电路板3与电池2沿手机的宽度方向排列且电池保护电路板3的长度方向与手机的长度方向一致，充电接口电路板1上对应电池保护电路板3的位置设有第一BTB连接器、对应电池2的位置设有第三BTB连接器，主控电路板4上对应电池保护电路板3的位置设有第二BTB连接器、对应电池2的位置设有第四BTB连接器，第一BTB连接器与电池保护电路板3的第一端31通过第一导线5连接，第二BTB连接器与电池保护电路板3的第二端32通过第二导线6连接，第三BTB连接器与第四BTB连接器通过第三导线7连接，第二BTB连接器和第四BTB连接器分别与主控电路板4上的充电管理芯片电连接。
该手机在进行大电流充电时，电流经充电接口电路板1上的充电接口11、第一BTB连接器、第一导线5进入电池保护电路板3，最后进入电池2。相较于现有技术，大电流充电通路不需经过主控电路板4上的连接器，降低了大电流通路中的阻抗，从而降低了手机充电过程中所产生的热量。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
