Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lithium battery, especially a lithium battery integrated module. BACKGROUND

[0002] The soft package lithium battery is only a liquid lithium ion battery with a polymer shell. In terms of structure, it is packaged with aluminum plastic film. In the case of hidden safety hazards, the soft package battery will at most be inflated and cracked. The existing soft package battery core model is less, which cannot meet the market demand.

[0003] The main factor is that the soft package lithium battery is an irregular module, so how to form a predetermined arrangement and install and fix it is the key to the design.

[0004] For example, Chinese patent CN202322986208.2 uses a heat conducting plate to realize its support, thereby ensuring the installation stability of the soft package lithium battery, but the structure affects the heat dissipation of the adjacent lithium battery to a certain extent, and the soft package lithium battery is soft as a whole, so the positioning area is limited to the position of the upper and lower tabs, so there are certain disadvantages.

[0005] Among them, the soft package lithium battery is preferably applied to a fixed scene, thereby improving its stability, such as energy storage equipment. UTILITY MODEL CONTENTS

[0006] The main purpose of the utility model is to provide a lithium battery integrated module, aiming at improving the existing soft package lithium battery structure, making it convenient to assemble, and at the same time having high stability.

[0009] The groove is provided on the opposite wall surface of the first positioning shell and the second positioning shell, and the groove is used for placing the soft package lithium battery,

[0010] The two frame parts are mutually adhered at the adapter end, and a limiting gap is provided at the position away from the corner end of the frame part;

[0011] The soft package lithium battery is attached to the positioning diaphragm, the positioning diaphragm extends out of the peripheral wall of the soft package lithium battery, and the positioning diaphragm is clamped in the limiting gap;

[0012] The series structure is used for connecting and surrounding the plurality of module individuals to form a main body, and the peripheral wall of the main body is provided with a cover plate.

[0013] In actual design, the soft package lithium battery is first attached to the positioning diaphragm to realize the preliminary positioning of the soft package lithium battery, fix the shape thereof as an individual, and the positioning diaphragm can improve the pulling strength of the lithium battery;

[0014] Meanwhile, the limiting layer of the positioning diaphragm is fixed through the limiting gap, thereby facilitating the limiting of the soft package lithium battery, and meanwhile, the soft package lithium battery is clamped in the groove between the first positioning shell and the second positioning shell, thereby realizing the protection of the soft package lithium battery, and thereby making it a module individual;

[0015] Through the combination of multiple module individuals in a series structure, an integrated module is formed, and the structural stability is good. BRIEF DESCRIPTION OF DRAWINGS

[0044] In the embodiment of the utility model, the corner end of the first positioning shell 11 and the second positioning shell 12 is a separate extension block 51, and the arrangement of the extension block can effectively provide a gap between the upper end and the lower end of the soft package lithium battery and the main body, thereby protecting the positive and negative poles.
