Embodiment Construction

[0045] "Schematic configuration of a battery module"

[0046] refer to Figure 1 to Figure 3 A battery module according to an embodiment of the present disclosure is described. figure 1 It is six views (front view, right side view, left side view, bottom view, plan view, and rear view) of the battery module 100 . figure 2 is a perspective view of the battery module 100 . image 3 is an exploded perspective view of the battery module 100 . Figure 4 is a perspective view of the battery cell.

[0047]The battery module 100 has end plates 102 and 103 as first and second regulating members. The end plates 102 and 103 are placed in fixed positions (substantially at right angles) near the ends of the bottom plate 101 . The bottom plate 101 is a plate made of metal such as iron. The bottom plate 101 is provided with ribs for increased strength. The circuit board 104 is fixed on the end board 102 . Circuit elements constituting a circuit for controlling the battery module are...

Abstract

The application discloses a battery module, an electronic apparatus, an electric power storage system, an electric power system, and an electric vehicle. A battery module includes a plurality of battery supports each having a face orthogonal to the stacking direction, and a side face, the battery supports each containing a plurality of cells and being made of an insulating material, a coupling part that is located between the face of one battery support and the face of another adjacent battery support, and contracts in the stacking direction upon stacking the battery supports to bring the faces of the battery supports into intimate contact, a group of cells including the battery supports stacked with the coupling part being placed between the battery supports, a base plate, and first and second regulating plates placed facing each other in a standing position on the base plate, the first and second regulating plates sandwiching the group of cells arranged between the first and second regulating plates and stacked with the coupling part being contracted.

Description

technical field [0001] The present disclosure relates to battery modules, electronic devices, power storage systems, power systems, and electric vehicles. Background technique [0002] In the prior art, a lithium ion secondary battery using carbon as an anode, a lithium transition metal composite oxide as a cathode, and a carbonate compound as an electrolytic solution is commonly used. Lithium-ion secondary batteries configured in this way perform better than nickel metal hydride batteries (aqueous batteries) because carbonates are stable to redox and can deliver higher voltages compared to water or other organic solvents. higher energy density and larger capacity. Therefore, lithium ion secondary batteries are widely used as secondary batteries for electric tools, notebook computers (PCs), cellular phones, video cameras, digital cameras, and the like. [0003] In recent years, in addition to the above-mentioned applications, lithium ion secondary batteries have become mor...
