Potting battery pack module and potting method

Abstract

The invention provides a potting battery pack module and a potting method. The potting battery pack module comprises two battery cell supports which have a same structure and are connected in an involution manner. The battery cell supports comprise a first battery cell support and a second battery cell support. The first battery cell support and the second battery cell support are connected in theinvolution manner along a length direction of a battery cell. A convex edge extending towards an inner side is arranged on an edge of each battery cell support. A plurality of battery cell cavities and a plurality of aluminum tube cavities are arranged on the first battery cell support, and the aluminum tube cavities are arranged between the adjacent battery cell cavities. Problems of a complex battery pack packaging process and battery pack thermal runaway prevention are effectively solved. A glue is poured into the module so that the battery cell is fullly contacted except for a positive electrode and a negative electrode, the battery cell is axially wrapped in an insulating glue, and the axial direction of the battery cell is in full contact with the insulating glue to form heat insulation and insulation layers.

Description

technical field [0001] The invention relates to the field of new energy technologies, in particular to a glue-filling battery pack module and a glue-filling method. Background technique [0002] At present, the new energy industry is developing rapidly. As the core of the development of electric vehicles, medical care, energy storage equipment and other industries, the performance of power battery packs has received sufficient attention, especially the safety of battery packs, which has attracted attention in various related fields. enough attention. Reasonable bracket design and glue potting to isolate a single cell can fully reduce the man-hours on the assembly line and provide sufficient safety guarantees. Even if an internal short circuit occurs in a single cell, it will not cause thermal runaway. Therefore, whether the design of the bracket is reasonable and the glue filling method between the bracket and the battery cells have become the focus of the battery pack indu...

AI Technical Summary

Problems solved by technology

[0003] The battery pack modules at this stage are: 1) The battery pack module has no glue filling and no isolated cells; when an internal or external short circuit occurs in the cells, thermal runaway is caused;

[0004] 2) The bracket is relatively heavy and complicated, and the replaceability is not high, which leads to high mold costs and increases the customer's use cost
