Abstract

The invention discloses a battery cell module support with high energy density, and relates to the technical field of battery modules, the battery cell module support comprises a conductor bottom plate, a plurality of first battery cells and a plurality of second battery cells, the top surface and the bottom surface of the conductor bottom plate are uniformly provided with a plurality of welding tongue pieces, and the peripheries of the plurality of welding tongue pieces are uniformly provided with a plurality of welding point groups; the plurality of first battery cells are in one-to-one correspondence connection with the welding point groups on the top surface of the conductor bottom plate, and the plurality of second battery cells are in one-to-one correspondence connection with the welding tongue pieces on the bottom surface of the conductor bottom plate. The first battery cells and the welding point groups are connected together, the spare space between the adjacent first battery cells is utilized during installation, the plurality of cylindrical bosses are arranged in the space, the plurality of cylindrical bosses are externally connected to the same circumference, and the circumference is used for positioning and placing the mounting holes of the cylindrical first battery cells. Therefore, a circle of wall thickness material is not needed to form the mounting hole, the space is saved, the volume density of the module is improved, the structure is simple, the size is small, the precision is easy to control, and the assembly difficulty is low.

Description

technical field [0001] The invention belongs to the technical field of battery modules, and in particular relates to a battery module bracket with high energy density. Background technique [0002] In the field of batteries, batteries are a general term, while batteries, modules and battery packs are different stages in battery applications. In the battery, in order to safely and effectively manage hundreds of individual cells, the cells are not randomly placed in the case of the power battery, but placed in an orderly manner according to modules and packages. The smallest unit is the cell, a group of cells can form a module, and several modules can form a battery pack. [0003] Battery cell: The battery cell is the smallest unit of a power battery and also an electrical energy storage unit. It must have a high energy density to store as much electrical energy as possible. In addition, the life of the battery cell is also the most critical factor. The damage of any battery...
