Abstract: This application relates to the technical field of energy storage devices, and in particular, to a device, a battery pack, and a battery module. The battery module includes a battery cell and an insulation board. The insulation board includes a body portion and a first bulge. The first bulge includes a sidewall and a top wall that close in to form an accommodation cavity. At least a part of an electrode terminal is accommodated in the accommodation cavity, and the top wall covers a part of the electrode terminal, thereby reducing a risk of letting metal particles or other impurities enter a position between the battery cells, where the metal particles are generated during welding. This reduces difficulty of cleaning the battery module, and improves safety and reliability of the battery module.

Abstract: Embodiments of this application provide a battery frame, a battery group, a battery pack, and a method for assembling a battery group. The battery frame according to the embodiments of this application includes at least two frames. The at least two frames are sequentially connected along a first direction. Among the at least two frames, any two adjacent frames are rotatably connected to each other, so that the battery frame is foldable. The foldability of the battery frame according to the embodiments of this application diversifies the battery frame effectively.
