在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。

本申请中出现的“多个”指的是两个以上(包括两个)。
本申请中，电池单体可以包括锂离子二次电池单体、锂离子一次电池单体、锂硫电池单体、钠锂离子电池单体、钠离子电池单体或镁离子电池单体等，本申请实施例对此并不限定。
本申请的实施例所提到的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池可以包括电池模块。
目前，从市场形势的发展来看，电动车辆成为汽车产业可持续发展的重要组成部分。电池为车辆本体的行驶和车辆本体中的各种电气元件的运行提供能量。电池内部电池单体数量众多，一般都是先构成电池模块后，再进行装配。在电池模块中，电池模块包括电池组、端板和连接件，电池组包括多个堆叠的电池单体，在电池组的两端分别设置端板，两个端板通过连接件连接以将电池单体紧固。然而，传统的端板制造成本较高，因此导致电池的制造成本高。
发明人经过研究发现，导致上述问题的原因在于，电池单体在充放电过程中会发生膨胀，为避免因电池单体膨胀对端板造成破坏，需要端板具有较高的结构强度。因此，传统的端板通常会设置较多的加强结构以提高端板的结构强度，但设置较多的加强结构会提高端板的用料成本和制造成本，进而提高电池的制造成本。
基于以上考虑，为了降低端板的制造成本，同时保证端板的结构强度，发明人经过深入研究，设计了一种端板，该端板包括沿第一方向依次设置的第一连接部、第一横梁和第二连接部，第一横梁沿第二方向延伸，第二方向垂直于第一方向；其中，第一连接部包括沿第三方向相对设置的第一内侧壁和第一外侧壁，第三方向垂直于第一方向和第二方向；第一内侧壁为平面壁，第一内侧壁的面向电池模块的电池单体的一侧和第一横梁的面向电池单体的一侧共面；第一外侧壁为斜面壁，第一外侧壁从第一横梁向远离第一横梁并向靠近第一内侧壁的方向倾斜延伸，第一外侧壁的两端分别连接于第一横梁和第一内侧壁。
在正常使用时，第一方向平行于电池单体的高度方向，第三方向平行于电池单体的厚度方向，即在电池单体的高度方向上，第一连接部、第一横梁和第二连接部自下而上依次设置，在电池模块中，多个电池单体沿第三方向堆叠，端板抵接于电池模块的位于两端的两个电池单体的大面(大面指电池单体在第三方向上的壁面)。
电池单体在充放电过程中会发生膨胀，而电池单体的最大膨胀力一般出现在大面的中部偏下的部分(在第一方向上，大面的中部位置及之下的部分)，即对应于端板的第一横梁和第一连接部之间的部位。为此，通过设置第一横梁和第一外侧壁，提高端板对应于电池单体中部偏下的部分的结构强度，以抵抗电池单体的最大膨胀力对端板的作用力，减轻因电池单体的膨胀对端板造成的形变，防止端板断裂导致紧固失效的情况发生，进而保证电池的安全性；同时，相比于在端板设置较多加强结构以提高端板的结构强度的方案，通过设置第一横梁，和将第一外侧壁设置为斜面壁，并将第一外侧壁的两端分别连接第一横梁和第一内侧壁，可以在不增设其他加强结构的条件下保证端板结构强度，降低端板的制造成本，进而有效地降低电池的制造成本。
