如图1所示，本申请公开了一种电池信息采样组件10，包括：电池采样控制单元13，柔性电路板12，柔性电路板12用于采集对应单体电池的信息且柔性电路板12直接连接电池采样控制单元13。
本申请中电池采样控制单元13与柔性电路板12直接连接，无需设置额外线束连接电池采样控制单元13和柔性电路板12，提升了电池模组20或电池包100内部的空间利空率，间接提升了电池模组20或电池包100的能量密度；同时也避免了线束因外因磨损而导致电池采集组件失效的问题。
柔性电路板12为多个，多个柔性电路板12间隔设置且多个柔性电路板12直接连接电池采样控制单元13。
多个柔性电路板12对应采集每个单体电池的电池信息后直接传输给电池采样控制单 元13。
如图2所示，本申请实施例中，柔性电路板12整体呈向上拱起的“拱形桥”结构。通过设置柔性电路板12的“拱形桥”的结构，可以减少电池信息采样组件在电池模组或电池包100内的占用空间。柔性电路板12包括向上拱起的且横截面为半圆型的弯曲部121以及设置于弯曲部121相对两侧的第一连接部122和第二连接部123。柔性电路板12通过第一连接部122与电池采样控制单元13连接，柔性电路板12通过第二连接部123与单体电池连接。
可以理解，柔性电路板12的弯曲部121也可以设置为向下凹陷并弯曲的形状。具体不做太多限制，在本申请基础上依据实际情况做适当的改进变型均应受本申请保护。本申请一实施例中，多个柔性电路板12的弯曲部121间隔设置，多个柔性电路板12的第一连接部122连接为一个整体。多个柔性电路板12的第一连接部122连接为一个整体后再与电池采样控制单元13连接，多个柔性电路板12的第一连接部122连接为一个整体的设计可以提高柔性电路板12与电池采样控制单元13的连接可靠性。
当然，本申请的柔性电路板12的结构不限于此，在另一些实施例中，多个柔性电路板12的第一连接部122也可单独直接与电池采样控制单元13连接。
本申请实施例中，电池采样控制单元13的数量为一个，柔性电路板12的数量为多个。例如，柔性电路板12的数量与单体电池的数量一致，每个柔性电路板12对应采集一个单体电池的电池信息。这样的设置方式可以保证即使一个柔性电路板12存在故障的情况下，不影响电池信息采样组件10对其他单体电池的信息采集。此外，柔性电路板12与单体电池一一对应的连接方式可以保证在部分柔性电路板10失效的情况下，仅需针对失效的柔性电路板10进行更换，针对性强并节省成本。
在另一个具体实施例中，柔性电路板12的数量与单体电池的数量不一致，柔性电路板12的数量少于单体电池的数量，即一个柔性电路板12对应采集多个单体电池的电池信息。例如，一个柔性电路板对应采集两个单体电池的电池信息。柔性电路板与单体电池的对应关系可以依据实际需要进行合理选择。
如图1所示，为实现电池信息采样组件10与单体电池21的快速连接，电池信息采样组件10还包括设置于柔性电路板12并用于与单体电池连接的插接件11。插接件11设置于柔性电路板12的端部，插接件11与单体电池21上的接插座211对插装配以实现电池信息采样组件10与单体电池的装配连接。
现有电池信息采样组件与单体电池通过焊接方式连接，工艺复杂，装配效率低；本申请电池信息采样组件10通过柔性电路板21上设置的插接件11与单体电池快速插接，提升了电池信息采样组件10的装配效率。柔性电路板12通过第二连接部123与插接件11连接。
本申请一实施例中，每个柔性电路板12上对应设置一个插接件11，进而实现一个柔性电路板12对一个单体电池进行信息采集。本申请另一实施例中，每个柔性电路板12上设有多个插接件11，进而实现一个柔性电路板12对多个单体电池进行信息采集。
每个柔性电路板12上设置的插接件11的数量可以为多个，例如两个、三个或其他数 量，具体数量依据实际需要进行合理选择。多个插接件11以固定间距并排设置于一个柔性电路板12的端部。
多个插接件11的排布方式不限于此，还可以根据单体电池的排布方式进行适应性调整以满足插接件11与单体电池的易于实现且牢固的插接关系。
如图1和图3所示，本申请中柔性电路板12与电池采样控制单元13焊接，插接件11与柔性电路板12焊接。柔性电路板12上的铜薄片与插接件11上的针脚通过钎焊的方式进行连接，电池采样控制单元13上引出的针脚与柔性电路板12上的铜薄片通过钎焊方式进行连接。
可以理解，柔性电路板12与电池采样控制单元13的连接方式以及插接件11与柔性电路板12的连接方式不限于此。
本申请电池信息采样组件10还包括设置于插接件11背侧的加强板(附图未示出)。插接件11的背侧为远离单体电池的一侧。柔性电路板12与插接件11焊接后，加强板与柔性电路板12固定连接。插接件11设置于柔性电路板12的一面上，加强板设置于柔性电路板12的另一面上。加强板通过胶粘的方式设置于柔性电路板12的另一面上。加强板与柔性电路板胶粘后，在加强板、插接件11以及柔性电路板12的外围涂覆黏胶，进而保证加强板、插接件11以及柔性电路板12之间更为牢固的连接关系。
本申请一实施例中，电池信息采样组件10包括多个加强板，每个插接件11的背侧设置一个加强板。本申请另一实施例中，电池采样组件包括一个加强板，每个插接件11均与该加强板粘接固定。本申请再一个实施例中，电池采样组件包括多个加强板，每个加强板上固定连接多个插接件11。
本申请实施例中，电池采样控制单元13为BIC板(BIC板即为电池信息采集器)，BIC板上设有定位孔131以及卡接位132。电池信息采样组件10通过电池采样控制单元13上设置的定位孔131使电池支架22与电池信息采样组件10定位装配。卡接位132为凹槽，电池支架22上的卡扣221嵌入卡接位132中卡合进而实现电池信息采样组件10的固定。
本申请实施例中，电池采样控制单元13上的定位孔131为四个。卡接位132为多个并且以固定间隔均匀设置于电池采样控制单元13的上边沿和下边沿。设置于电池采样控制单元13上边沿的卡接位为四个；设置于电池采样控制单元13下边沿的卡接位为四个。卡接位具体数量的设置不限于此，可以根据实际需求进行合理调整。
如图4和图5所示，一种电池模组20，电池模组20包括依次堆叠排序的多个单体电池21，多个单体电池21的端部设有电池支架22，多个单体电池21的端部伸入电池支架22。电池信息采样组件通过插接件11与单体电池21的接插座211插接连接。装配杆23一端插入电池采样控制单元13的定位孔131，另一端伸入电池支架22内，进而实现电池采样控制单元13的定位装配。装配杆23的数量为多个，具体为四个。电池支架22上设有卡扣221，卡扣221嵌入电池采样控制单元13上的卡接位132内，进而实现电池采样控制单元的固定。电池信息采样组件的柔性电路板12之间具有一定间隔，该间隔构成了电池支架22上的卡扣避让位14，电池支架22上的部分卡扣221穿过卡扣避让位14后与电池采样控制单元13 上边沿的卡接位132配合实现卡合功能。待电池信息采样组件10与电池支架22装配后，保护盖(附图未示出)再与电池支架22装配进而实现对电池信息采样组件的保护。
本申请电池信息采样组件10通过柔性电路板12采集内部的各单体电池21的电压、温度等电池参数信息，并将参数信息直接传输至电池采样控制单元13，通过电池采样控制单元13最终将参数信息传输至电池管理系统，实现对单体电池的检测。
如图6所示，一种电池包100，包括：上述实施例中的电池模组20。
根据本申请实施例的电池包100，包括至少一个采用上述电池信息采集组件10的电池模组20，在可以实现电池包100内多个电池模组20的多个单体电池21的信息采集的前提下，电池信息采集组件10的工作稳定性更高，可以提高电池包100的使用安全性，电池信息采集组件10的布置位置更合理、空间占用更合理，可以间接改善电池包100内的空间利用率，提高电池包100的能量密度。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
