Problems solved by technology

Each existing battery module has four installation points, and the number of existing battery modules in the entire battery assembly is between 15 and 25. The installation of existing battery modules requires 60 to 100 fixing bolts, and the installation workload is large ; At the same time, installation gaps need to be reserved between the existing battery modules, occupying space, resulting in low integration efficiency of the battery assembly

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] see Figure 2 to Figure 11 The shown battery module structure is suitable for various integration methods, including a plurality of rectangular parallelepiped battery modules 4, and the battery module 4 is a first battery module 41 or a second battery module with the same structure. Group 42, characterized by:

[0030] The two ends of the battery module 4 are respectively provided with a concave-convex structure 5, and the concave-convex structure 5 is formed by connecting a convex part and a concave part; The concave-convex structure 5 at one end of the negative electrode of the battery module 4 is misaligned to form a mortise-tenon connection; the positive and negative electrodes of multiple battery modules 4 are connected to form a row of battery packs, and multiple rows of battery packs are connected together through long screws 9 . Constitute a battery mo...

Abstract

The invention relates to a battery module structure applicable to various integration modes, which comprises multiple cuboid-shaped battery modules, wherein each battery module is a first battery module or a second battery module with the same structure. The battery module structure is characterized in that both ends of the single battery are provided with a concave-convex structure, and the concave-convex structure is formed by connecting a convex portion and a concave portion; the concave-convex structure at the positive electrode end of one battery module is correspondingly matched with the concave-convex structure at the negative electrode end of another battery module in a staggered manner to form mortise-tenon connection; the positive electrodes and negative electrodes of the multiple battery modules are connected to form a row of battery packs, and multiple rows of battery packs are connected together by long bolts to form a battery module group. The battery module structure can improve the integration efficiency of a battery assembly, reduce the assembly workload and improve the assembly efficiency, and can further save the integration space.

Description

technical field [0001] The invention relates to a power system of a new energy vehicle, in particular to a battery module structure suitable for various integration modes. Background technique [0002] At present, the existing battery modules 1 used in new energy vehicles are mainly prismatic batteries, see figure 1 , using fixing bolts 2 to directly fix the end of the existing battery module 1 on the battery case 3 . Each existing battery module has four installation points, and the number of existing battery modules in the entire battery assembly is between 15 and 25. The installation of existing battery modules requires 60 to 100 fixing bolts, and the installation workload is large ; At the same time, installation gaps need to be reserved between the existing battery modules, which takes up space, resulting in low integration efficiency of the battery assembly. [0003] CN 205488306U discloses "a power battery module for electric vehicles", which includes a battery inst...
