- the present embodiment it is possible to realize packaging of a secondary battery that is robust and highly versatile by connecting a plurality of battery blocks using a DIN rail. That is, in the battery module as shown in FIG. 1 that does not use a DIN rail, it is usually packaged by being housed in a case according to the shape of the battery module so that the connection between the battery blocks cannot be broken. .
- a battery module having a regular shape as shown in FIGS. 4 (A)-(B) can be easily housed in a case, but a battery module having an irregular shape as shown in FIG. It is hard to store in the case. Therefore, it is necessary to limit the assembly form of the battery block to a regular shape, or to prepare cases adapted to various shapes.
- the former makes it difficult to customize the shape of the battery pack according to the installation space, and the latter increases the cost of the case.
- a plurality of battery blocks can be assembled in an arbitrary shape while ensuring robustness.
- the battery block can be connected in all directions of the X axis, the Y axis, and the Z axis.
- the rigidity of the whole battery module can be improved compared with the case where two battery blocks are individually connected by screwing or the like.
- the guide member is provided in the direction in which the DIN rail passes in the direction parallel to the electrode surface on the long side surface and the short side surface, and provided on the same plane parallel to the electrode surface. It is easy to connect.
- the invention according to the present embodiment may be specified by the items described below.
- the battery block is formed in a rectangular parallelepiped shape, The battery according to item 1, wherein the guide member is provided on at least two adjacent surfaces among four surfaces other than the two opposing surfaces on which the positive electrode external terminal and the negative electrode external terminal of the battery block are respectively arranged. block.
- the guide member is provided in a direction in which the rail passes in a direction parallel to a surface on which the terminal is arranged on each installation surface, and a position where the distance from the surface on which the terminal is arranged is equal on each installation surface Item 3.
- 100 battery block 500a, 500b, 500c, 500d, 500e, 500f battery module, 10a first bracket, 10b second bracket, 10c third bracket, 20a, 20b lid member, 30a, 30b positive external terminal member, 11a first Guide member, 12a 2nd guide member, 13a 3rd guide member, 14a 4th guide member, 15a 1st support member, 16a 2nd support member, 17a 3rd support member, 200, 210 DIN rail, 250 screws, 300 plate Mold mounting member, 310 plate mounting member, 350 screws, 400, 410 L-shaped mounting member, 450 screws.
- the present invention can be used for in-vehicle secondary batteries and power storage systems.
