Abstract

The invention discloses a soft pack battery module and a manufacturing method thereof. The battery module comprises soft pack battery modules, a heat conduction sheet and front and rear bus bar assemblies, wherein the soft pack battery modules are stacked and connected to form a whole soft pack battery module; the front bus bar assembly and the rear bus bar assembly are connected to the front end and the rear end of the whole soft pack battery module; the bus bars on the front bus bar assembly and the rear bus bar assembly are contacted with leads of corresponding soft pack cathode mixes; the bottom surface of the whole soft pack battery module forms a cooling surface; and the cooling surface is contacted with the heat conduction sheet. Thus, the battery modules are assembled to the whole soft pack battery module, series and parallel connection of different requirements can be realized, and the applicability is strong; the bottom of the whole battery module is provided with the heat conduction sheet, thereby achieving good heat conduction performance; and an embedded molding process is adopted between a heat conduction frame and a plastic piece and between the whole soft pack cathode mix module and the bus bar assemblies, thereby improving the strength of the assembly formed by the heat conduction frame and the plastic piece and achieving better product consistency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric vehicle accessories, in particular to a pouch battery module and a manufacturing method thereof. Background technique [0002] Soft-pack batteries refer to lithium batteries whose shells are made of soft packaging materials (usually aluminum-plastic composite films), which have many advantages such as small size, light weight, high specific energy, high safety, and flexible design. The structure of the soft-packed battery is packaged with aluminum-plastic film, and the positive and negative electrodes of the battery also use the battery tab structure, which is different from the usual plastic-cased and metal-cased batteries. Because the shape of the soft-packed battery is soft, it is not easy to fix, and it is prone to scratches, pits, creases, etc., so multiple soft-packed batteries are fixed to each other and multiple soft-packed power batteries are connected in series and...
