Problems solved by technology

[0002] The assembly process of the existing soft-pack power battery modules is relatively complicated, and the stacking of cells during assembly may easily cause the tabs of the cells to be eccentric, making it difficult to pass through the tabs, which in turn leads to low efficiency of battery module assembly. At the same time, the existing The heat dissipation effect of the soft-pack power battery module is not good, and the structural strength is not reliable, which will cause the soft-pack power battery module to work at high temperature for a long time, which will easily lead to corresponding failures of the battery, that is, the stability of the electrical performance of the module and the stability of the module. The safety of the vehicle cannot be guaranteed, further affecting the normal driving of the vehicle

Abstract

The invention discloses a battery core stacking module and a soft package battery module, and belongs to the technical field of power batteries. The battery core stacking module comprises a pluralityof battery core stacking assemblies which are stacked in a first direction, wherein each battery core stacking assembly comprises a single battery core, a heat dissipation piece and a rubber frame assembly, the single battery cores are stacked in the first direction, the heat dissipation piece is arranged on the single battery core and is connected with the single battery core to form a combined battery core, the rubber frame assemblies are arranged around the single battery cores in a surrounding manner and are connected with the combined battery cores, and the rubber frame assembly of one battery core stacking assembly is connected with the rubber frame assembly of the other battery core stacking assembly. The battery core stacking module and the soft package battery module are good in installation stability and connection reliability, high in assembly precision and good in heat dissipation performance.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a cell stacking module and a pouch battery module. Background technique [0002] The assembly process of the existing soft-pack power battery modules is relatively complicated, and the stacking of cells during assembly may easily cause the tabs of the cells to be eccentric, making it difficult to pass through the tabs, which in turn leads to low efficiency of battery module assembly. At the same time, the existing The heat dissipation effect of the soft-pack power battery module is not good, and the structural strength is not reliable, which will cause the soft-pack power battery module to work at high temperature for a long time, which will easily lead to corresponding failures of the battery, that is, the stability of the electrical performance of the module and the stability of the module. The safety of the vehicle cannot be guaranteed, further affecting the normal dri...
