Multi-layer battery module assembly structure

Abstract

The invention relates to a multi-layer battery module assembly structure which comprises a plurality of battery module structures and a water-cooling heat conduction structure, wherein the battery module structures are arranged side by side in an array at intervals; each battery module structure comprises a plurality of first battery cell monomers arranged side by side, module bracket structures which are arranged on two corresponding side edges of each first battery cell monomer and extend along the length direction of the first battery cell monomer, and a module partition plate which covers the plurality of first battery cell monomers and is connected with the two module bracket structures; the plurality of second battery cell monomers cover the module partition plate and are arranged in one-to-one correspondence with the plurality of first battery cell monomers; the water-cooling heat conduction structure comprises a water-cooling plate which is arranged between each first battery cell monomer and each second battery cell monomer and covers the module partition plate, and the water-cooling plate is connected with the module support structure; the space utilization rate of the battery pack can be improved, the structural stability is higher, and the risk of tension crack failure caused by collision and impact of internal parts of the battery pack is avoided.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to a multi-layer battery module assembly structure. Background technique [0002] The battery is the core component of a power vehicle. In terms of the manufacturing cost of a pure electric vehicle, the battery also accounts for the highest proportion. With the vigorous development of passenger electric vehicles, users are paying more attention to their battery life; under the condition of a certain cell energy density , Assemble more cells, the larger the battery capacity, the longer the battery life. [0003] The length and width of different models of passenger electric vehicles currently produced are not very different, and the Z-direction space is rationally used to design a two-layer or multi-layer structure, which can assemble more cells and increase the capacity of the battery. However, due to the limited space in the battery pack, there are many parts inside the batt...

AI Technical Summary

Problems solved by technology

However, due to the limited space in the battery pack, there are many components inside the battery pack. If the internal parts of the battery pack cannot be properly installed, when the battery pack is subjected to a collision impact, the internal components are prone to the risk of cracking and failure, resulting in battery failure. Package failure, and even affect the safety of the vehicle
