- 1A to 1C the same components as those in FIG. 6 are denoted by the same reference numerals, and description thereof is omitted.
- the assembled battery 1 includes a battery cell 2, an end plate 3, a metal band 4, and a connecting member 5.
- 1A shows a state in which the assembled battery 1 is assembled
- FIG. 1B shows the components excluding the battery cell 2
- FIG. 1C shows the battery cell 2.
- the battery cell 2 gradually expands in the process of repeated charge and discharge during use. This is due to the following reason.
- the battery cell 2 is dried after applying a material as an electrode material to a metal foil, and further wound in a compressed state in the thickness direction and sealed in a cell can together with an electrolytic solution.
- the electrode material expands due to heat generated by the electrode chemical reaction or Joule heat.
- the material that has expanded at the beginning of its life will eventually return to its original state, but the residual stress generated during the compression process during production will be gradually released, and as charging and discharging are repeated, the thickness of the electrode will increase and the thickness of the entire battery cell will increase. It will also increase.
- the electrode thickness continues to increase, the electrode will buckle in due to the compression force from the restraint by the cell can.
- the electrolyte in the gap generated by buckling is vaporized even at room temperature, and as the temperature rises, the volume increases and the thickness of the battery cell increases accordingly.
- FIG. 1C there is an electrode terminal at the upper end of the battery cell 2, and the wound electrode was wound as shown by an arrow 7 around the direction of the long dimension of the rectangular battery.
- the battery cell 2 hardly expands in the axial direction of winding, and the battery cell 2 has a gap above the wound electrode group and the cell can on the upper side where the terminal of the battery cell 2 is located.
- the battery cell 2 expands in the direction of a larger area because it hardly expands even during operation.
- the lithium secondary battery cell expands and becomes wide in use.
- the space in which the battery can be mounted is limited, so parts and structures other than the battery are often placed close to each other. There is concern about interfering with. Therefore, the dimensional change of the assembled battery 1 needs to be kept to a minimum.
- a method for increasing the rigidity of the member by increasing the size of the member constituting the assembled battery 1 or using a material having a high Young's modulus and the expansion of the battery cell 2 to the component member.
- the assembled battery tends to be large and heavy, and it is not preferable for in-vehicle applications that require a reduction in size and weight.
- the assembled battery shown in FIG. 1A has a structure that suppresses the increase in size and weight as much as possible.
- a plurality of battery cells 2 are arranged in series so that the surfaces with large areas face each other.
- the end plate 3 is arranged in a pair at both ends thereof, and connects the two plates with two plates each having a height dimension the same as that of the battery cell 2 and a width dimension smaller than the long side of the long side surface of the battery cell 2.
- the connection member 5 is used.
- the two plates are arranged at both ends of the long side surface of the battery cell 2 arranged at the end, and a bolt fastening portion 6 that is fastened to the base is provided at the end opposite to the end surface of the battery cell 2.
- the two plates and the connecting member 5 are joined together by a method such as welding.
- the surface of the battery cell 2 having a large area at the end has a portion that does not contact the end plate 3 at the center.
- the center of the surface having a large area expands.
- the end plate 3 of the present invention does not come into contact even when the center of the battery cell 2 expands, and the reaction force due to the expansion can be reduced. As a result, the amount of deformation in the long side direction of the entire assembled battery 1 when the battery operates can be smaller than that of a single end plate.
- resin or metal may be used, but it is desirable that the bending elastic modulus is 150 GPa or more.
- the area ratio of the plurality of end plates 3 to the wide surface of the battery cell 2 is desirably 20% or more in total.
- the metal band 4c described later must not interfere with the terminals on the upper part of the battery cell 2, and the end plate 3 needs to have a size that satisfies this.
- the pair of end plates 3 are fastened to each other with a metal band 4.
- the metal band 4 plays a role of suppressing the entire assembled battery 1 from being extended by a reaction force generated by the expansion of the battery cell 2.
- it is required to have a high longitudinal elastic modulus like high-tensile steel.
- the configuration of the metal band 4 is such that two short side surfaces of the assembled battery 1 are connected to each other on the side surface of the metal band 4a and below the side surface of the metal band 4b.
- the top surface of the metal band 4c and the bottom surface of the metal band 4d are each two, that is, the assembled battery 1 as a whole has a total of eight.
- FIG. 2A shows a model used for the analysis, and shows a state where the assembled battery 1 is attached to the base, excluding the battery cell 2.
- the battery pack 1 has a symmetrical shape in the central section in the longitudinal direction and the lateral direction, a quarter of the whole is modeled, and the symmetry plane is a boundary that restrains displacement in a direction perpendicular to the symmetry plane.
- the analysis is equivalent to what is modeled and analyzed as a whole.
- FIG. 2B is a modified view of the end plate 3, the metal band 4, and the connecting member 5 obtained from the analysis.
- the displacement of the end plate 3 is small because the lower side is fixed by bolt fastening, and the displacement is larger than the lower side because there is no such restriction on the upper side.
- the battery cell is installed at least on the top surface of the metal band 4c.
- the upper side of the end plate 3 can also be restrained by any method, for example, by providing a base and fastening it.
- the bottom surface of the metal band 4d has a role of reducing the longitudinal displacement of the assembled battery 1 like the other metal bands 4, and prevents the dropping by supporting the battery cell 2 when the assembled battery 1 is assembled. It also has a function. Regarding this function, the metal band 4b on the lower side of the short side surface can be substituted by making the lower side surface of the metal band 4b L-shaped and supporting it at both ends of the battery cell 2. In this case, if the assembled battery 1 is used by being bolted to some base, the displacement on the lower side of the assembled battery 1 can be made almost zero, so there is no problem even if the bottom surface of the metal band 4d is not provided.
- the end plate 3 may not be divided into two upper and lower sides on both short sides, but may be an integral unit in which the upper and lower sides are coupled as shown in FIGS. 2A to 2B.
- the end plate 3 When it is necessary to suppress the temperature rise of the battery cell 2 during the operation of the battery pack 1, and it is cooled by blowing air through the gaps between the battery cells 2 arranged in series, it is better to divide the battery cell into two upper and lower parts.
- the short side surface does not require a cooling mechanism, and may be a single body.
- the connecting parts are U-shaped parts as shown in FIG.
- the end plate 3 is provided with a connecting member insertion hole 8 into which the connecting part is fitted, and the connecting part is fitted into this part during assembly.
- the jig for assembling the assembled battery 1 is used for positioning the connecting member insertion hole 8 of the end plate shown in FIG. 4, it can be assembled without connecting parts.
- FIG. 5A shows the surface on the opposite side which contact
- FIG. 5C shows the inside of the end plate viewed from the side.
- the end plate 3 is a rectangular parallelepiped, and has a rectangular shape as shown in FIG. 5B when viewed from the inner side surface.
- the end plate 3 is pushed by the reaction force due to the expansion of the battery cell 2, the displacement at the center is the largest.
- the assembled battery of the present invention can also be applied to transportation equipment such as an electric vehicle and a hybrid vehicle, or a storage battery for home use, an emergency storage power source, and the like.
