Abstract

The invention relates to a battery module structure and a battery module. The battery module structure comprises a casing, an insulated bracing frame and at least two softly packed batteries; the sidewalls of every two adjacent softly packed batteries cling to each other; the insulated bracing frame is provided with tab through grooves in one to one correspondence with positive and negative tabs of the batteries; the top of the insulated bracing frame is provided with positive and negative electrode blocks; each positive tab penetrates the corresponding tab through groove and is then fixed tothe positive electrode block, and each negative tab penetrates the corresponding tab through groove and is then fixed to the negative electrode block; and the bottom of the insulated bracing frame isprovided with a flange towards the top of the casing, the outer side surface of the flange is fit to the inner side surface of the top of the casing, and the flange is in connected to the top of the casing by punching. The battery module comprises a housing and multiple battery module structures arranged therein. The problems that the softly packed batteries are low in assembling efficiency and itis hard to check a live-line fault and maintenance is inconvenient after assembly are solved.

Description

technical field [0001] The invention relates to the technical field of battery structures, in particular to a battery module structure and a battery module group. Background technique [0002] Batteries are widely used in production and life, especially in the automotive industry. Commonly used batteries include lithium batteries, square batteries, soft-pack batteries, etc. Among them, soft-pack batteries are packaged with a layer of polymer film on a liquid ion battery , has the advantages of good safety performance and small internal resistance. Specifically, in the case of potential safety hazards, the pouch battery will only blow up and crack at most, instead of exploding like steel-shell and aluminum-shell batteries; at the same time, currently The minimum internal resistance of domestic pouch battery cells can be less than 35mΩ, which greatly reduces the self-consumption of the battery. Due to the above advantages of pouch batteries, they are used more by people than o...
