Embodiment Construction

[0038] The invention will be further described below in conjunction with the accompanying drawings, but it is not used to limit the scope of the present invention.

[0039] like Figure 1 to Figure 6 As shown, a high energy density pouch battery module, including battery components and boxes;

[0040] The battery assembly is tightly combined by a plurality of neatly arranged battery cells 8 and the middle frame 9 between the multiple battery cells 8. The battery assembly is compressed and reinforced by a box body, and the box body is provided with two An end plate 6, an insulating plate 7 is arranged between the battery core 8 and the end plate 6; two transverse poles 901 are arranged on the top of the middle frame 9, and one side of the pole 901 has a groove, so The other three sides of the pole 901 are planes, the groove is engaged with the middle frame 9, the side of the pole 901 opposite to the groove is welded with a connection row 4, and the two sides of the pole 901 ar...

Abstract

The invention provides a high-energy-density soft-pack battery module, which comprises a battery module and a box body. The battery module is formed by tightly combined a plurality of cells and a middle frame among the cells, the battery module is pressed and strengthened by the box body, and the cells and the middle frame are connected in series through a connecting row; two transverse pole columns are arranged at the top of the middle frame; the box body is formed by fixedly connecting two end plates and four pressing strips, and an insulating plate is arranged between the battery core and the end plate; the coupling row is connected with the general row at the position of the end plate, and the coupling row is connected with an FPC board. The invention realizes threadless connection, eliminating the risk of easy loosening of threaded joints; the FPC board is used for collecting voltage and temperature, which saves the cost and space of battery module. The performance is stable, safeand reliable. The main components are lightweight designed, which greatly reduces the weight of module and realizes the requirement of high energy density of module. The volume energy density of thewhole battery module system is increased by 15%.

Description

technical field [0001] The invention belongs to the field of soft-pack battery modules, and in particular relates to a high-energy-density soft-pack battery module structure. Background technique [0002] At present, new energy batteries mainly have three structures: square, cylindrical, and soft pack. The module composed of square aluminum shell cells is large in size and heavy in weight. Compared with the battery box with fixed size requirements, the space utilization rate is low, which is not conducive to the expansion of battery pack capacity and the overall design of the system; the module components composed of cylindrical steel shell cells The complex process and the separation of the positive and negative electrodes at both ends are extremely unfavorable to the wiring harness arrangement of the battery system and the overall design of the system, and because the shell material is steel, there is a very large electrical safety hazard (explosion). At the same time, th...
