Embodiment Construction

[0020] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0021] A soft-packed battery cell moduleless battery unit, including a long aluminum frame 1, a number of stacked cells 2 are evenly distributed in the aluminum frame 1, and a flexible circuit board 5 (FPC) is connected to the stacked cells 2 ; A cell limiting block 3 is arranged between adjacent stacked cells 2 , and a unit insulating block 4 is arranged in the middle of the cell limiting block 3 .

[0022] A processing technology for a soft-pack battery cell without a module, comprising the following steps:

[0023] Step 1: Aluminum extrusions form a suitable aluminum frame 1;

[0024] Step 2: Glue the soft-packed cells and cushioning materials together and stack them into blocks to make stacked cells 2;

[0025] Step 3: Insert the stacked cell 2 into the aluminum frame 1 by the manipulator;

[0026] Step 4: Weld the cell limit block 3 between...

Abstract

The invention discloses a flexibly packaged battery cell module-free battery unit and a processing technology. The flexibly packaged battery cell module-free battery unit comprises a long-strip-shapedaluminum frame, a plurality of stacked battery cells are uniformly distributed in the aluminum frame, and flexible circuit boards are connected to the stacked battery cells; a battery cell limiting block is arranged between every two adjacent stacked battery cells, and a unit insulating block is arranged in the middle of each battery cell limiting block. According to the invention, the heat transfer path of the module unit can be shortened, and the available space in the Z direction is increased.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a soft-pack battery cell without a module and a processing technology. Background technique [0002] Electric vehicles are the main trend of today's automotive technology development. The battery pack system is the only source of power for electric vehicles. One of the most important components of the battery pack system is the battery module. According to the different packaging forms of the batteries, the batteries are divided into cylindrical batteries, square batteries, and soft-pack batteries. For the integration of pouch cells, the most common method is to first integrate the single cells into a module, and then integrate the module into the battery pack system. [0003] Due to the weak strength of the pouch cell itself, the first step in the integration of the battery system requires adequate protection of the cell. In the second step of battery sys...
