Abstract

The invention relates to batteries and provides a battery pack. The battery pack according to the present invention comprises a casing (1) and at least two cell module blocks (2) arranged in the casing (1), and the cell module blocks (2) It includes at least one battery module (21), a beam (3) is arranged between two adjacent battery module blocks (2), and a support structure (4) is arranged on the beam (3), The size of the support structure (4) can be adjusted along the distance direction between the adjacent battery module blocks (2), so that the side walls on both sides of the support structure (4) can be The side walls of the cell module blocks (2) abut against each other, and the side walls of the cell module blocks (2) located on the outermost side are in the row of the cell module blocks (2). It can be in contact with the casing (1) in the cloth direction. The battery pack can effectively improve the space utilization rate of the battery pack and increase the arrangement of battery cells to increase the energy density.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack. Background technique [0002] As the core power component of electric vehicles, battery packs play a vital role in the handling performance, safety, and service life of electric vehicles. Traditional batteries are arranged directly in the box frame, and end plates are provided on both sides of the batteries to fix the batteries. However, the arrangement of the end plate will increase the space occupied by the battery pack, reduce the number of battery cells arranged in a limited space, and reduce the space utilization rate of the battery pack. Contents of the invention [0003] In view of this, the present invention aims to provide a battery pack, which can effectively improve the space utilization rate of the battery pack and increase the arrangement of battery cells to increase the energy density. [0004] In order to achieve the above object, technical so...
