Battery assembly

A battery assembly includes: a battery module stack in which at least one battery module is stacked and formed; a cover portion coupled to one side of the battery module stack; and a substrate portion coupled to an outer surface of the cover portion, where the cover portion includes a cover member coupled to the battery module stack; and a protruding member protruding in an outward direction from the cover member and contacting an inner surface of the substrate portion, the substrate portion including an overlapping region which is a region overlapping with the protruding member when viewed in the outward direction, in which a through hole passing through the overlapping region in the outward direction is formed, and forming a pad region having conductive performance in a region surrounding the through hole in the substrate portion. 一种电池组件，包括：电池模块堆叠，其中堆叠并形成至少一个电池模块；覆盖部，耦接至电池模块堆叠的一侧；以及基板部，耦接至覆盖部的外表面，其中，覆盖部包括覆盖构件，其耦接至电池模块堆叠；以及突出构件，从覆盖构件在向外方向上突出并且与基板部的内表面接触，基板部包括重叠区域，重叠区域是当在向外方向上观察时与突出构件重叠的区域，在重叠区域中形成有在向外方向上穿过重叠
