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: This application relates to the technical field of energy storage devices, and in particular, to a box body, a battery pack, and a device. The box body includes a first beam and a second beam. The first beam and the second beam intersect each other, and are connected by a connecting portion, and partition the box body into a plurality of accommodation spaces. The first beam includes a body and a recess. The recess is recessed inward relative to the body. The connecting portion is disposed in the recess. In this way, a joint position between the first beam and the second beam will not protrude from a lateral surface of the first beam, thereby preventing a short circuit of a battery cell caused by puncture of or damage to an insulation film outside the battery cell, and improving safety performance of the battery.
