Abstract

The invention relates to the field of batteries, and provides a battery module and a battery pack. The battery module comprises a plurality of battery core assemblies, at least one spacing structure and at least one tab bracket, wherein the plurality of battery core assemblies are arranged in an array along the thickness direction, each battery core assembly comprises at least one battery core unit, the spacing structures are arranged between two adjacent battery core assemblies, the end portions of the spacing structure are convexly arranged relative to the end surfaces of the battery core units, the tab bracket is arranged at one ends of the plurality of battery core assemblies, at least one first inserting groove is formed in one side, facing the spacing structure, of the tab bracket, and the first inserting groove is matched with the end portion of the spacing structure in an inserting manner. Based on the structure, when the tab bracket is extruded, the tab bracket extrudes the spacing structure which is matched with the first inserting groove in an inserting manner, but does not directly extrude the battery core assembly, so that the spacing structure can bear a relatively large extrusion force, and the battery core assembly only needs to bear a relatively small extrusion force so as to reduce the extrusion degree of the tab bracket on the battery core assembly.

Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to a battery module and a battery pack. Background technique [0002] A battery module usually includes a plurality of cell assemblies arranged in an array along the thickness direction, a tab support connected to one end of each cell assembly, and an end plate connected to a side of the tab support away from the cell assembly. However, based on the above structure, when the end plate is squeezed, the end plate will be squeezed to the lug bracket, and the rear lug bracket will directly transmit the extrusion force to each cell assembly, causing the cell assembly to be easily damaged. It may even lead to a safety risk in the battery module. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a battery module to solve the technical problem that the tab bracket of the existing battery module is easily directly squeezed to the ba...
