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.

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: A battery pack is provided. The battery pack includes a first partition piece, a battery row, and a shielding member. The first partition piece is located between two batteries adjacent to each other in a first direction in the battery row. An upper surface of the first partition piece is lower than an upper surface of a top cover. A recess is formed between the battery row and the first partition piece. The shielding member includes a first shielding portion and a second shielding portion. The first shielding portion overlays all explosion-proof valves of the battery row. A passage is disposed between the first shielding portion and the upper surface of the battery row. The passage is configured to guide a fluid to flow along the first direction and is provided with a downward opening. The second shielding portion closes off a part of the opening facing the recess directly.

Abstract: This disclosure relates to a battery pack, including: an upper cover (1) including an upper cover body and an explosion-proof exhaust structure (3), the upper cover body including a top plate (11) in an upper part and a side plate (12), and an opening in a lower part, the explosion-proof exhaust structure (3) being disposed on the side plate (12), and an exhaust duct being provided between the top plate (11) and the explosion- proof exhaust structure (3); and a lower housing (2), where the upper cover (1) is disposed above the lower housing (2), the lower housing (2) is disposed with batteries (5), and each of the batteries is provided with an explosion-proof valve (51). The exhaust structure (3) of the upper cover (1) of the battery pack is disposed on the side plate (12). Hot gas rapidly increased in the battery pack due to thermal runaway is exhausted from a lateral side by the explosion-proof exhaust structure (3) disposed on the side plate (12), thereby effectively reducing safety hazards to a passenger compartment caused by the hot gas exhausted from an upper end of the battery pack. In addition, the battery pack can be manufactured by improving an existing upper cover structure, thereby possessing advantages of cost-efficiency and significant effects.
