[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. They are currently the primary power source for modern digital products such as mobile phones and laptops. In the automotive sector, lithium-ion batteries are also gradually replacing traditional gasoline and diesel engines as one of the power sources for automobiles, and the resulting electric vehicles have become an important product in China's new energy vehicle industry.
[0003] When applied to automobiles, multiple lithium batteries need to be connected in series and parallel to form a battery module. The assembly of the battery module involves stacking and connecting the batteries one by one into plastic components. The plastic components in the assembled battery module, arranged from bottom to top, include a base plate, several intermediate plates, a top plate, and a safety box for explosion-proof protection of the lithium batteries. After multiple layers of lithium batteries are stacked, a top plate and a base plate are installed at the top and bottom respectively. Adjacent layers of lithium batteries are isolated by intermediate plates. Finally, supporting management circuits for protection, monitoring, cooling control, and charge / discharge control are connected, and the entire module is then encapsulated in a protective shell to form the product.
[0004] During the battery module assembly process, lithium batteries need to be compressed and then fitted with steel strips. Existing compression devices have complex structures and are insufficient for compressing the battery from multiple angles. Utility Model Content

[0039] Please continue reading.
