下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。当一个元件被认为是“设置于”另一个元件， 它可以是直接设置在另一个元件上或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本申请。本文所使用的术语“或/及”包括一个或多个相关的所列项目的任意的和所有的组合。
本申请实施例提供了一种电池模组，包括电芯组件，所述电芯组件包括多个电芯单元，所述多个电芯单元堆叠设置。所述电池模组进一步包括第一侧板和第二侧板，沿所述多个电芯单元堆叠的方向，所述第一侧板和所述第二侧板分别设置于所述电芯组件的两个侧边并与所述多个电芯单元固定。
上述电池模组通过将第一侧板和第二侧板固定设置于电芯组件的两侧，并且电芯组件的多个电芯直接堆叠设置，取消了现有技术中的电芯支架结构，有效降低了电池模组的装配误差和制造成本。
本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施方式及实施方式中的特征可以相互组合。
请参阅图1和图2，电池模组100包括电芯组件10，所述电芯组件10包括多个堆叠设置的电芯单元11。所述电池模组100进一步包括第一侧板21和第二侧板22，沿所述多个电芯单元11堆叠的方向，所述第一侧板21和所述第二侧板22分别设置于所述电芯组件10的两个侧边并与所述电芯组件10固定。在本申请的实施例中，所述第一侧板21和所述第二侧板22分别设置于所述电芯组件10相对的两个侧边，在其他实施例中，所述第一侧板21可以设置于所述电芯组件10的侧边，所述第二侧板22可以设置于所述电芯组件10的底部，本申请不限定于此。
请继续参阅图3、图4和图5，在本申请的其中一个实施例中，所述第一侧板21的内侧设置收容一个或多个电芯单元11的第一凹槽211，所述第二侧板22的内侧设置收容一个或多个电芯单元11的第二凹槽221。在本申请的实施例中，所述多个电芯单元11与所述多个第一凹槽211或所述第二凹槽221一一对应，在其他实施例中，可以两个或多个电芯单元11设置在一个凹槽内，本申请不限定于此。所述电芯单元11部分收容在所述第一凹槽211和所述第二凹槽221内，有利于降低第一侧板21、第二侧板22和电芯组件10的装配难度，避免电芯组件10沿堆叠方向滑动。在本申请的实施例中，所述电芯单元11第一凹槽211与第二凹槽221的位置对齐，在其他实施例中，所述电芯单元11可以是异形电芯，所述第一凹槽211与所述第二凹槽221与所述电芯单元11匹配即可，凹槽的位置无须相互对齐。电芯单元11的一侧收容于所述第一凹槽211，所述电芯单元11相对的另一侧收容于所述第二凹槽221。所述第一凹槽211和所述第二凹槽221的形状与所述多个电芯单元11的侧面形状匹配，以适配不同类型的电芯单元11。所述电芯单元11包括极耳111，所述极耳111设置于所述第一侧板21和所述第二侧板22之间。
