AI Technical Summary
In the existing technology, during the stacking and extrusion process of battery modules, it is impossible to ensure that each cell is under pressure, which makes the cells prone to upward displacement in the Z-axis direction, affecting the flatness of the bottom surface of the module.
A modular cell stacking and extrusion device is used, including X-axis and Y-axis guide rail clamps and pressure head assemblies. By adjusting the position and number of guide rail clamps, it is ensured that each cell is pressed down. Springs are used to accommodate differences in cell height and prevent cell displacement.
This ensures that each battery cell is in a depressed state, guarantees the flatness of the module's bottom surface, improves the contact effect between the battery cell and the heating film or adhesive, and enhances the overall vehicle performance.
