目前，为了减少汽油等对环境的污染，电池被广泛应用于车辆、船舶或飞行器等用电装置中，为用电装置提供电力驱动。为了满足用电装置较高的动力需求，一般电池可以包括多个电池单体形成的电池包。
传统的电池包中，电池模块的电压和温度采样线束占用较大空间，导致该电池包的空间利用率较低。
本申请的发明人注意到，传统的电池包的空间利用率较低的原因在于：传统的电池包中，电池管理模块需要通过转接件如转接线束与采样板连接，进而获取电池模块的电压和温 度数据，该转接件占用了电池包的内部空间，进而导致电池包的空间利用率较低。
为了解决传统的电池包的空间利用率较低的问题，本申请的发明人经过深入研究，设计了一种电池模块采样组件，使采样单元直连于电池管理模块单元，省去了转接线束，可提升电池包的空间利用率。
本申请实施例公开的电池模块采样组件和/或电池包可以但不限用于车辆、船舶或飞行器等用电装置中。用电装置可以为但不限于手机、平板、笔记本电脑、电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。其中，电动玩具可以包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等，航天器可以包括飞机、火箭、航天飞机和宇宙飞船等等。可以使用具备本申请公开的电池包等组成该用电装置的电源系统，这样，便于为用电装置提供电力驱动，也可提升电池包的空间利用率。
图1示出了本申请一实施例的一种车辆1的结构示意图，车辆1可以为燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。车辆1的内部设置电池包10。例如，在车辆1的底部或车头或车尾可以设置电池包10。电池包10可以用于车辆1的供电，例如，电池包10可以作为车辆1的操作电源，用于车辆1的电路系统，例如用于车辆1的启动、导航和运行时的工作用电需求。在本申请的另一实施例中，电池包10不仅仅可以作为车辆1的操作电源，还可以作为车辆1的驱动电源，替代或部分替代燃油或天然气为车辆1提供驱动力。
车辆1的内部还可以设置马达20以及控制器30，控制器30用来控制电池包10为马达20的供电，例如，用于车辆1的启动、导航和行驶时的工作用电需求。
图2示出了本申请一实施例中的电池包10的结构示意图。
在一些实施例中，参阅图2、图3及图4，本申请一实施例提供的一种电池模块采样组件，包括采样模块组件以及电池管理模块组件。
采样模块组件包括对应地电性连接于电池模块100的采样单元200，采样单元200包括第一采集端子210。电池管理模块组件包括与采样单元200对应的电池管理模块单元300，电池管理模块单元300具有与第一采集端子210适配的第二采集端子310，以将电池管理模块单元300电性连接于采样单元200。
该电池模块采样组件使用时，可将第一采集端子210与第二采集端子310相配接，使得电池模块100的电池单体110的电压信号和温度信号等可以通过采样单元200、第一采集端子210和第二采集端子310传递至电池管理模块单元300，以实现电池单体110的电压信号和温度信号等信号的有效传递和采集，电池管理模块单元300也可以对电池模块100的电池单体110进行热管理和/或安全性管理等，可以理解，采样单元200直连于电池管理模块单元300，省去了连接于采样单元200和电池管理模块单元300之间的转接线束，可提升电池包10的空间利用率，也能缩短装配工时，提高装配效率。
需要说明的是，对应地电性连接于电池模块100的采样单元200中，以及与采样单元200对应的电池管理模块单元300中的对应可以为一一对应，也可以为一对多地对应、也可以为多对一地对应。
在一些实施例中，请参阅图2及图4，每一电池模块100包括多个电池单体110，第一采集端子210具有多个第一采集端口211，以与电池模块100的多个电池单体110对应地电性连接。
如图2及图4所示，多个第一采集端口211可与多个电池单体110一一对应地电性连接。
那么，电池管理模块单元300可通过采样单元200的第一采集端子210的第一采集端口211获取对应的电池单体110的电压信号和温度信号等信号，更方便进行电压信号和温度信号等信号的有效传递和采集。
在另一些实施例中，第一采集端子210的第一采集端口211可以分别与多个电池单体110电性连接，以采集多个电池单体110的电压信号和温度信号等信号。
在一些实施例中，请参阅图4、图5及图6，采样模块组件包括多个采样单元200，每一采样单元200的第一采集端子210还具有第二采集端口212。任意两个采样单元200中，其中一采样单元200的第一采集端子210的第二采集端口212，和另一采样单元200的第一采集端子210的第二采集端口212彼此电性连接。
也就是说，任意两个采样单元200中，一采样单元200采集的数据可通过另一采样单元200传递至与另一采样单元200相连的电池管理模块单元300。
如此，一个电池管理模块单元300可通过彼此电性连接的两个采集单元200而采集至少两个电池模块100的电池单体110的电压信号和温度信号等信号，拓宽了该电池模块采样组件的应用范围。
在一些实施例中，任意两个采样单元200中，其中一采样单元200的第一采集端子210的第二采集端口212，和另一采样单元200的第一采集端子210的第二采集端口212可通过连接导线彼此电性连接。

如此，其中一第一采集端子210的第二采集端口212和另一第一采集端子210的第二采集端口212借助于第一接头组件241和第二接头组件242彼此电性连接。
可以理解，一个电池管理模块单元300能够采集至少两个电池模块100的电池单体110的电压信号和温度信号等信号。另外，第一接头组件241和第二接头组件242可拆卸地连接，方便拆卸与装配，且便于对电池模块采样组件进行批量生产。
在一些实施例中，请参阅图7及图8，第一接头组件241上设有插槽部，第二接头组件242上设有与插槽部相配合的插接部，以在插接部插设于插槽部时使第二接头组件242和第一接头组件241能够电性连接。

在一些实施例中，请参阅图7及图8，插槽部包括第一插槽2411和第二插槽2412，插接部包括第一插接部2421，以及与第一插接部2421相连的第二插接部2422，其中，第一插接部2421插设于第一插槽2411，第二插接部2422插设于第二插槽2412。
利用第一插接部2421插设于第一插槽2411，且利用第二插接部2422插设于第二插槽2412，使得插接部更牢固地插设于插槽部，提高第一接头组件241和第二接头组件242彼此电性连接的可靠性，也能更好地采集电池单体110的电压信号和温度信号等信号。
在一些实施例中，第一插槽2411和第二插槽2412沿第一方向F 1层叠设置，第一插接部2421沿第二方向F 2插设于第一插槽2411，第二插接部2422沿第二方向F 2插设于第二插槽2412，第一插接部2421沿第三方向F 3的尺寸大于第二插接部2422沿第三方向F 3的尺寸。
可以理解，第二插接部2422连接于第一插接部2421沿第一方向F 1的一侧，可使插接部更牢固地插设于插槽部，提高第一接头组件241和第二接头组件242彼此电性连接的可靠性。
如图7及图8所示，第一方向F 1为上下方向，第二方向F 2为左右方向，第三方向F 3为前后方向，也就是说，上侧的第二插接部2422沿左右方向插设于第二插槽2412，下侧的第一插接部2421沿左右方向插设于第一插槽2411。且第一插接部2421沿前后方向的尺寸大于第二插接部2422沿前后方向的尺寸。
在一些实施例中，第二接头组件242包括位于沿第三方向F 3相对且间隔设置的两个侧边部2413，第二插槽2412形成于两个侧边部2413之间，以使插设于第二插槽2412的第二插接部2422限位于两个侧边部2413之间，可提高第一接头组件241和第二接头组件242彼此电性连接的可靠性。
在一些实施例中，请参阅图4及图6，每一采样单元200的第一采集端子210具有两个第二采集端口212，同一采样单元200的第一采集端子210的两个第二采集端口212分别连接有第一接头组件241和与第一接头组件241相适配的第二接头组件242。
如此，相邻的三个采样单元200中，中间的采样单元200可通过其上的第一接头组件241与相邻的一采样单元200的第一采集端子210的第二采集端口212上的第二接头组件242适配连接，中间的采样单元200还可通过其上的第二接头组件242与相邻的另一采样单元200的第一采集端子210的第二采集端口212上的第一接头组件241适配连接。
既可使相邻的两个采样单元200彼此电性连接，又可提高装配效率。
在一些实施例中，请参阅图5，采样单元200还包括连接组件，每一采样单元200的第一采集端子210被配置为借助连接组件与电池单体110对应地电性连接。
如此，电池管理模块单元300可通过对应的采样单元的第一采集端子210和连接组件获取多个电池单体110的电压信号和温度信号等信号，以进行电压信号和温度信号等信号的有效传递和采集。
在一些实施例中，第一采集端子210的多个第一采集端口211与多个电池单体110一一对应地电性连接。
