在本公开实施例中，充电保护板110和放电保护板120可以为相互独立的两个保护板，它们可以设置在电芯的两侧。充电保护板110上可集成有各种电路，放电保护板120上也可集成有各种电路。

其中，在对所述电池组件进行充电的情况下，充电电流可绕过所述放电保护板120，并经由所述充电保护板110进入所述电芯。
在本公开实施例提供的终端中，终端的电池组件包括电芯、用于充电保护的充电保护板和用于放电保护的放电保护板，所述电芯分别与所述充电保护板和所述放电保护板连接，在对所述电池组件进行充电的情况下，充电电流可绕过所述放电保护板，并经由所述充电保护板进入所述电芯。如此，通过设置两个相互独立的充电保护板和放电保护板，进入终端的充电电流可以只需到达用于充电保护的充电保护板，而无需到达用于放电保护的放电保护板，如此可以缩短充电电流传输的通路，进而可减少通路发热损耗。
在本公开实施例中，在所述电池组件放电的情况下，来自所述电池组件的电流可经过所述放电保护板120流向所述充电保护板110，以对通路中的元件进行供电。
亦参照图1，在本公开实施例中，所述终端还可包括充电接口150、第一电路板160和第二电路板140。所述充电接口150设置在所述第一电路板160上。充电接口150可以为USB接口和Type C接口等，充电器(图未示出) 可以与充电接口150相连接，并在充电器接入外部电源时可以向终端进行充电。在本公开实施例中，第二电路板140可以为终端主板，第一电路板160可以为终端的小板。第一电路板160和第二电路板140可以为相互独立的两个电路板，且它们可以如图1所示分别设置在电芯130的两侧。

在本公开实施例中，充电保护板110可以如图1所示作为单独的部件与第一电路板相连接，也可以与第一电路板160集成在一起，例如充电保护板110作为第一电路板160的一部分集成在所述第一电路板上。同理，放电保护板120可以如图1所示作为单独的部件与第二电路板140相连接，也可以与第二电路板集成在一起，例如放电保护板120作为第二电路板的一部分集成在所述第二电路板上。充电保护板110和/或放电保护板120的这种集成式安装可以充分利用终端内的空间，因而可以提高终端的空间利用率，同时可以保证终端的体积更加紧凑。
在对终端的电池组件进行充电的过程中，充电电流可以经由充电接口150进入，并可经由第一电路板160直接传输至充电保护板110，进而传输至电芯130以给电芯130充电。而在终端的电池组件进行放电的过程中，来自电芯130的电流可依次经过放电保护板120、第二电路板(例如主板)140而送至充电保护板110和第一电路板(例如小板)160。
参照图2，在本公开实施例提供的电池组件中，电芯130可为对称式设计，上下各一对正负极耳。电芯130可以分别与充电保护板110和放电保护板120连接。如此，在对电池组件进行充电时，电流可以通过下方的充电保护板110进入电芯；而在电池组件放电时，电流可以通过上方的放电保护板120流出，给例如第二电路板(例如主板)140上的各个元件供电，当然还可以给第一电路板(例如小板)160上的各个元件供电。
在本公开的一个实施例中，所述充电保护板110可包括第一控制模块和第一控制金属-氧化物半导体场效应晶体管(Metal-Oxide-Semiconductor Field-Effect Transistor,MOSFET)，其中，所述第一控制模块与第一控制MOSFET连接，所述第一控制模块具有充电保护控制功能，所述第一控制MOSFET具有充电通路控制功能。发明实施例通过第一控制模块可以实现充电保护控制功能，例如防止充电过流、过充保护等，通过第一控制MOSFET可以控制充电通路，例如调节通路中某一元件的电压等。第一控制模块和第一控制MOSFET可以相互匹配以更好地实现充电保护电路功能。
相应地，在本公开的另一个实施例中，所述放电保护板120可包括第二控制模块和第二控制MOSFET，其中，所述第二控制模块与所述第二控制MOSFET连接，所述第二控制模块具有放电保护控制功能，所述第二控制MOSFET具有放电通路控制功能。本公开实施例通过第二控制模块可以实现放电保护控制功能，例如防止放电过流、过放保护、短路保护等，通过第二控制MOSFET可以控制放电通路，例如调节通路中某一元件的电压等。第二控制模块和第二控制MOSFET可以相互匹配以更好地实现放电保护电路功能。
在本公开实施例中，所述第二控制模块可具有短路自恢复功能。如果发生放电过流或者短路事件，可以不用通过充电的方式激活放电通路，而可以在短路或者放电过流事件解除之后自动恢复放电通路。
在本公开实施例中，充电保护板110上可设置充电保护电路，放电保护板120上可设置放电保护电路。充电保护电路和放电保护电路可相互分离，互不干扰。下面参照图3-4对本公开实施例提供的放电保护电路和充电保护电路进行进一步阐释。
图3为本公开实施例提供的一种放电保护电路的示意图。参照图3，Rd1、Rd2为电阻，Cd1、Cd2为电容，Rd1、Rd2、Cd1、Cd2均为保护集成电路的外围电路器件。Pd1为保险丝。R_ID1为电池ID识别电阻，ID1为电池ID识别的端口，用于确认电池是否为本厂家所生产的电池，以达到防伪的目的。B+和B-为电芯端正极荷负极，Pd+和Pd-为电池正极和负极。Qd1为控制MOSFET(第二控制MOSFET)。U1为控制模块(第二控制模块)，VDD为连接正极的电压，VSS为连接负极的电压，DO为连接Qd1的管脚，VM为 检测口，例如过流检测口。
Qd1为控制MOSFET(第二控制MOSFET)，用于放电通路控制，如果有放电过流发生，可通过调整(例如拉低)DO管脚关闭放电通路，同时不影响充电通路，而通过放电通路MOSFET的寄生二极管可以续流。
R SNS1为放电保护电路的采样电阻，DHG_M和DHG_P为用于连接到电量计的两个端口，DHG_M和DHG_P通过导线分别连接到R SNS1的两端。
各个部件的连接结构可以如图3所示。需了解的是，在图3所示电路中，U1可去掉充电过流、充电过压功能，以减小面积。Qd1可去掉充电通路控制MOSFET，以减小面积。同时由于只用考虑放电过流能力，走线可以不用像相关技术那样严格控制阻抗，这样可以保护板的宽度更窄。U1可仅做放电功能保护，且可具有短路自恢复功能，这样如果发生放电过流或者短路事件，可以不用通过充电的方式激活，而是在短路或者放电过流事件解除之后自动恢复放电通路。
