Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. FIG. 1 is a perspective view showing the entire structure of a battery pack, and FIG. 2 is a perspective view showing the structure of a non-aqueous electrolyte secondary battery. FIG. 3 is a perspective view showing the configuration of the resin frame, and FIG. 4 is a front view and a side view showing the configuration of the side plate.

In this embodiment, as shown in FIG. 1, a battery pack including seven nonaqueous electrolyte secondary batteries 1 will be described. As shown in FIG. 2, each nonaqueous electrolyte secondary battery 1 is not shown inside a housing-shaped battery case 1 a made of a stainless steel plate whose front and rear widths are smaller than the vertical depth and the horizontal length. Two long cylindrical winding type power generating elements are arranged side by side and housed, and the upper end opening of the battery container 1a is closed by a rectangular lid plate 1b made of stainless steel plate. Positive terminal 1c
And a negative electrode terminal 1d protruding therefrom. Further, the battery container 1a of the nonaqueous electrolyte secondary battery 1 is provided with a safety valve 1e on the right side surface. The safety valve 1e is formed by attaching a metal film having a thickness of about 50 μm to a hole opened on a side surface of a battery container 1a made of a stainless steel plate and closing the metal film when the inside of the battery becomes abnormally high pressure. Is to prevent the rupture of the nonaqueous electrolyte secondary battery 1 itself by degassing. However, if such a thin metal foil is exposed by the safety valve 1e, it may be easily damaged only by hitting a sharp object from the outside, and the nonaqueous electrolyte secondary battery 1 may be damaged.
May become unusable. In practice, the nonaqueous electrolyte secondary battery 1 is covered with a thick tubular heat-shrinkable resin (not shown) from above and thermally shrinks the heat-shrinkable resin to cover the periphery. Since the heat-shrinkable resin is made of an extremely thin resin film, when the inside of the battery becomes high pressure and the safety valve 1e is opened, the resin film is also broken by this pressure, so that the operation of the safety valve 1e is not hindered. Absent.

As shown in FIG. 1, each of the non-aqueous electrolyte secondary batteries 1 is a module with both front and rear sides sandwiched between a pair of resin frames 2 and 2. A module is a structural unit of an assembled battery including one nonaqueous electrolyte secondary battery 1 and a pair of resin frames 2 surrounding the same. The assembled battery shown in FIG. 7 are arranged side by side and sandwiched between the side plates 3 and 3 to be integrated. Therefore, in this module, the number of the modules to be arranged and sandwiched can be freely changed, so that an assembled battery including any number of non-aqueous electrolyte secondary batteries 1 can be manufactured.

Each of the resin frames 2 is a frame formed by molding a polybutylene terephthalate (PBT) resin. As shown in FIG. 3, one of the resin frames 2 forming a pair has a concave battery housing portion 2a in which a front half of the nonaqueous electrolyte secondary battery 1 of FIG. A frame body having the same shape as the above-mentioned frame body is rotated by half a turn so that the front-rear direction is reversed, and is arranged on the rear side in FIG. Then, the rear half of the nonaqueous electrolyte secondary battery 1 of FIG. 2 is fitted into the battery housing portion 2a of the other resin frame 2, and the end faces of the pair of resin frames 2 are overlapped. Become a module. When assembling such a module, actually, a buffer material (not shown) is attached to the battery housing portion 2 a of each resin frame 2, particularly near the bottom, and the battery container 1 of the nonaqueous electrolyte secondary battery 1 is
a to be filled. Therefore, when the resin frames 2, 2 forming a pair of modules are sandwiched from both sides in the front-rear direction, the battery housing portions 2 a,
Since the buffer material is pressed and interposed between the battery container 2a and the battery container 1a of the nonaqueous electrolyte secondary battery 1, the nonaqueous electrolyte secondary battery 1 can be housed without looseness, and the external Even when the battery receives a shock or a vibration from the battery, the shock or the like directly applied to the nonaqueous electrolyte secondary battery 1 can be reduced.

As shown in FIG. 3, each of the resin frames 2 has an end face on the front side, that is, a battery housing 2a when a module is formed.
A window 2b is formed on the outer end face facing the outside opposite to the non-aqueous electrolyte secondary battery 1 inside, which is open at most of the portion except the peripheral portion. Further, since the window portion 2b is continuously opened to the front side of the left and right side surfaces, the upper and lower portions of the resin frame 2 are formed of a pair of shielding plates elongated vertically in the rear side of the left and right side surfaces. They are connected only through the parts 2c, 2c. Accordingly, when the resin frames 2 and 2 are paired to form a module with the nonaqueous electrolyte secondary battery 1 interposed therebetween, the shielding plates 2c and 2c of both the resin frames 2 and 2 are adjacent to each other at the center without any gap. This non-aqueous electrolyte secondary battery 1
Will block the center of the left and right sides. In addition, since these shielding plate portions 2c, 2c are disposed slightly outside the left and right sides of the inner side surface of the battery accommodating portion 2a, they are not immediately in front of the left and right side surfaces of the nonaqueous electrolyte secondary battery 1, but are slightly spaced. Will be placed open. Therefore, further to the right of the safety valve 1e formed on the right side surface of the nonaqueous electrolyte secondary battery 1, the shielding plate portion 2 adjacent to the right side of the pair of resin frames 2
Since the safety valves 1c and 2c are arranged with a gap therebetween, even if the safety valve 1e is opened and the electrolyte is ejected together with the high-pressure gas when the battery is abnormal, the safety plate 1c is blocked by the shielding plates 2c and 2c and the surrounding area is wide. It is possible to prevent scattering in the range.

Each of the resin frames 2 has an uneven portion 2d at each of the four corners of the outer end surface. Each uneven portion 2d is
In the case of FIG. 3 which is slightly smaller than the inner side surface of the battery accommodating portion 2a, two elliptical convex portions are protruded from a vertical flat surface located forward, and two elliptical convex portions are alternately formed with the convex portions. Are formed. Further, the left and right uneven portions 2d are formed such that the positions of the convex portions and the concave portions are reversed. Therefore, when the modules are arranged in the front-rear direction and the outer end face of the resin frame 2 on the front side of the module on the rear side and the outer end face of the resin frame 2 on the rear side of the module adjacent to the front side are overlapped back to back, The convex portions of the concave and convex portions 2d of one resin frame 2 are fitted into the concave portions of the concave and convex portions 2d of the other resin frame 2, and these adjacent modules are sandwiched from the front and rear directions, so that the vertical and horizontal directions Can be prevented from shifting from each other. Further, at the time of assembling, by fitting these uneven portions 2d, it becomes possible to position the arranged modules. Further, between adjacent modules, one of the resin frames 2 adheres back-to-back at these uneven portions 2d, so that a gap is generated between the nonaqueous electrolyte secondary batteries 1 and 1 of these modules. Therefore, between adjacent modules, the windows 2 of the resin frames 2
Since the cooling air in the left-right direction can flow between the side surfaces of the non-aqueous electrolyte secondary batteries 1 and 1 through b and 2b, the non-aqueous electrolyte secondary battery 1 of the assembled battery can be reliably cooled. become. If a gap is provided between the widest side surfaces of the nonaqueous electrolyte secondary batteries 1 and 1 as described above, an abnormality detection sensor for detecting swelling of the side surface of the battery container 1a due to a rise in pressure inside the battery. Can be attached, and the safety of the assembled battery can be improved.

The pair of resin frames 2 and 2 are formed in a substantially symmetrical shape in order to use the same component by rotating it half a turn as described above. However, only the concave and convex portions 2d are formed so that the positions of the convex portions and the concave portions are different between the left and right sides, and thus are not exactly left-right symmetric.

In each of the resin frames 2, two through holes 2e are formed below the uneven portions 2d, 2d on the right and left sides of the lower portion and near the center on the left and right above the window portion 2b. . These through holes 2e are provided with through bolts 4 shown in FIG.
The periphery of the resin frame 2 is the same as the width of the resin frame 2 in the front-rear direction so that the through bolts 4 are not exposed except at both ends of the battery pack when the modules are arranged. Covered with. That is, as shown in FIG. 3, the lower two through holes 2e, 2e are formed as holes penetrating the lower frame portion of the battery accommodating portion 2a, and the upper two through holes 2e, 2e are formed. , Is formed in a cylindrical shape on the crosspiece above the battery accommodating portion 2a. Therefore, as shown in FIG. 1, seven modules are arranged in front and rear, four through bolts 4 are passed through the through holes 2e of each resin frame 2, and bolt holes 3d of the side plates 3, 3 arranged at both ends are provided. By screwing nuts to both ends of each through bolt 4 through
Each pair of the resin frames 2 and 2 of the individual modules can be sandwiched and fixed, thereby securely supporting the seven nonaqueous electrolyte secondary batteries 1. Further, in each module, since the through bolts 4 made of stainless steel are not exposed by being covered with the pair of resin frames 2 and 2, reliable insulation can be maintained, and the through bolts 4 can be secured. When nuts are screwed into both ends, each resin frame 2
Can be reliably held.

Each of the resin frames 2 has two through-holes 2e, 2e formed on a cross section above the battery accommodating portion 2a.
Between them, wiring locking portions 2f, 2f are protruded so as to face inward. Non-aqueous electrolyte secondary battery 1 for each module
The terminals 1c and 1d are connected in series between the terminals 1c and 1d of the nonaqueous electrolyte secondary battery 1 of the adjacent module by a connecting rod (not shown) arranged above the resin frame 2.
Further, to these terminals 1c and 1d, wiring to a management device for monitoring charge / discharge voltage and the like is connected. The wiring locking portions 2f, 2f of each resin frame 2 are used to lock the wiring when the wiring is pulled out through the upper part of each resin frame 2 and forward of the battery pack. It can be prevented from spreading above and to the side of the battery and hindering handling.

Each of the resin frames 2 has lid cover locking portions 2g projecting upward from both ends of the bar-shaped portion above the battery accommodating portion 2a. The lid cover locking portions 2g, 2g are disposed horizontally above the bar-shaped portion and are flat in the horizontal direction. The lid cover supporting portions are bent in a hook shape and protrude further above the lid cover supporting portions. It consists of a slide guide part. When such lid cover locking portions 2g, 2g are formed on each of the resin frames 2 of the seven modules of the assembled battery, the lateral edge of the flat lid cover 5 as shown in FIG. And can be slid in the front-rear direction. That is, for example, the left and right side edges of the front end of the lid cover 5 are first placed on the lid cover locking portions 2g, 2g on the uppermost part of the resin frame 2 on the rearmost side of the battery pack, and The lid cover 5 is engaged by being inserted between the sliding guide portion and the left and right side edges are sequentially moved while sliding the lid cover 5 forward.
The upper part of this assembled battery can be covered by engaging with the lid cover locking portions 2g, 2g. However, before attaching the lid cover 5, the work of connecting the connecting rod or connecting the wiring between the terminals 1c and 1d of each non-aqueous electrolyte secondary battery 1 is completed. In addition, these terminals 1c,
The wiring 1d is connected to the wiring locking portion 2 of each resin frame 2 as described above.
If they are locked together at f and 2f, they do not hinder the work of attaching the cover 5. The lid cover 5 is a rectangular flat plate made of resin, but has cutouts at two corners located at both ends on a diagonal line.
From here, the non-aqueous electrolyte secondary batteries 1,1
Terminals 1c and 1d are exposed. The terminals 1c and 1d of the seven non-aqueous electrolyte secondary batteries 1 are
Adjacent components other than those exposed at the notch of the lid cover 5 are connected in series by connecting rods, so that the pair of exposed terminals 1c and 1d serve as positive and negative terminals of the assembled battery. Note that, in the present embodiment, since an assembled battery in which an odd number of the nonaqueous electrolyte secondary batteries 1 are combined is described, the positive and negative terminals of this assembled battery are arranged at both ends on a diagonal line. In the case of an assembled battery in which the non-aqueous electrolyte secondary batteries 1 are combined, they are arranged at both ends of one of the right and left sides.

As shown in FIG. 1, the side plates 3 and 3 are made of a stainless steel plate having substantially the same size as the outer end surface of the resin frame 2, and are arranged at both ends in the front-rear direction in which seven modules are arranged. As shown in FIG. 4, each side plate 3 is made of a convex stainless steel plate having a flat surface arranged vertically, and the reinforcing portion 3a is formed by bending the lower end side and projecting horizontally to the opposite side to the module. Has formed. Ribs 3b, 3b formed by welding a stainless steel plate into an approximately right-angled isosceles triangle and welding two orthogonal sides are joined to both ends between the main body of the side plate 3 and the reinforcing portion 3a. Further, the side plate 3 forms a grip portion 3c by bending the upper end side of the main body having a convex shape and projecting horizontally to the opposite side to the module. As described above, each side plate 3 is not a mere flat stainless steel plate, but has upper and lower ends bent to form a reinforcing portion 3a and a gripping portion 3c, and ribs 3b, 3b are provided between the main body and the reinforcing portion 3a. Because it is joined,
It is possible to hold a heavy non-aqueous electrolyte secondary battery 1 module having seven modules arranged side by side with sufficient strength. In addition, the reinforcing portion 3a of each side plate 3 enhances stability when the assembled battery is installed, and also has a U-shaped notch as shown in FIG. Will be able to

As shown in FIG. 4, the side plates 3, 3 disposed at the front and rear ends of the seven modules are provided at the four ends on both sides near the center of the lower end of the convex main body and the center of the upper end. Bolt holes 3d are formed, and four through bolts 4 are passed through the through holes 2e of the resin frames 2 of the seven modules through these bolt holes 3d, and as shown in FIG. By screwing nuts to both ends of the bolt 4, the seven nonaqueous electrolyte secondary batteries 1 are connected to each pair of the resin frames 2, 2.
And fix it. At this time, the main body of each side plate 3 faces the outer end surface of the resin frame 2 at the outermost end. However, since the tip of the convex portion of the uneven portion 2d abuts, the main body of each side plate 3 is in contact with the opening edge of the through hole 2e. There is a slight gap between them. For this reason,
The bolts 3 of the side plates 3 are previously formed in the through bolts 4.
A washer (not shown) serving as a spacer is fitted on the module side through which the holes d pass, so as to eliminate a gap between the opening edge of the through hole 2 e of the resin frame 2 at the end. Therefore, when nuts are screwed into both ends of the through bolt 4 without the washer, the vicinity of the bolt hole 3d of the side plates 3 and 3 is bent toward the opening edge side of the through hole 2e of the resin frame 2 at the end. And the resin frame 2 can be stably held and fixed. Each of the through bolts 4 may have a bolt head at one end, or may have a nut screwed to one end thereof and fixed thereto by welding or the like. The screw connection can be made only at the other end.

Each of the side plates 3 is provided with a pair of claws 3e, 3e protruding toward the module to be clamped, at the upper portions of both ends of the main body. These claw portions 3e, 3e are formed by bending a plate piece protruding left and right from the main body of the side plate 3 toward the rear or the front, and holding both side surfaces of the upper end portion of the resin frame 2 at the end portion to be clamped. It is designed to be sandwiched from both sides.
The resin frames 2, 2, which form a pair with each module,
By fitting the non-aqueous electrolyte secondary battery 1 into a, the engagement is ensured without shifting in the up, down, left, and right directions, and the resin frames 2, 2 between the modules are also fitted into the recesses by the uneven portions 2d. Thereby, the engagement is ensured without shifting in the vertical and horizontal directions. However, if there are no claws 3e, 3e,
Since the side plate 3 and the resin frame 2 merely overlap,
The engagement becomes unstable. However, since each side plate 3 is provided with the claw portions 3e, 3e, the claw portions 3e, 3e are provided.
By sandwiching the resin frame 2 at least at the outermost end from both the left and right sides, it is possible to reliably engage and to stably fix the assembled battery. Moreover, in the present embodiment, since groove-like depressions are formed on both side surfaces of the resin frame 2 between which the claw portions 3e, 3e are sandwiched, it is possible to securely engage in the vertical direction. .

As shown in FIG. 4, at least one of the side plates 3 is provided with an oblong wiring hole 3f at the lower center of the main body. A management device (not shown) is attached to the end face, and a side plate cover 6 shown in FIG. 1 is attached.
The wiring holes 3f are connected to the terminals 1 of the seven non-aqueous electrolyte secondary batteries 1.
The wires connected to c and 1d and locked by the wire locking portions 2f of the respective resin frames 2 pass through the outside of the upper bar-shaped portion of the resin frame 2 at the outermost end, and are connected to the module from the module side of the main body of the side plate 3 to the module. Are holes that are drawn out to the opposite side, so that terminals 1c and 1d of the management device and each non-aqueous electrolyte secondary battery 1 are formed.
To be able to connect. Therefore, the management device of the assembled battery is connected to the terminals 1 c and 1 of the non-aqueous electrolyte secondary battery 1.
It is not necessary to arrange at the upper end where the connection with d is made, and the space efficiency can be increased by attaching to the side plate 3 at any end in the front-rear direction. The side plate cover 6 is for protecting the management device, and is screwed to the side plate 3. Note that the management device may be attached to both side plates 3 and 3, but if it is attached to one side, the wiring hole 3f may be formed only in this one side plate 3. However, these side plates 3, 3
Since the common device can be formed by making the left-right symmetric shape, the wiring hole 3f may be formed in both side plates 3 even when the management device is attached to only one side plate 3.

The side plates 3 and 3 have a stainless steel plate surface coated with an insulating material. Therefore, by surrounding the periphery of the nonaqueous electrolyte secondary battery 1 together with the insulating resin frame 2, the insulation of the whole battery pack can be improved. In addition, since the material itself is made of a stainless steel plate, it has sufficient rigidity, has high corrosion resistance against an electrolytic solution, moisture and salt, and the like, and can improve the safety of the battery pack.

According to the present embodiment, according to the present embodiment, the claw portions 3e are provided on the side plates 3, 3, so that the module of the nonaqueous electrolyte secondary battery 1 sandwiched between these side plates 3, 3 is surely provided. It becomes possible to support stably.
Further, by forming the wiring hole 3f in at least one of the side plates 3, the wiring can be drawn in and the management device can be attached, so that the space efficiency of the assembled battery can be improved.

In the above-described embodiment, the case where the through-bolt 4 is used for holding and fixing is shown. However, as long as a plurality of modules arranged in the front-back direction are held and fixed from both front and rear sides, such a bolt is used. The holding means is not limited to the shape, and may have any configuration.

In the above embodiment, the case where the resin frame made of resin is used has been described, but the material of the frame is not limited. Further, the nonaqueous electrolyte secondary batteries 1 arranged in the front-rear direction can be directly sandwiched between the side plates 3 and 3 without using these frames. In this case, the battery case 1a and the lid plate 1b of each non-aqueous electrolyte secondary battery 1 are provided with irregularities that fit with the adjacent non-aqueous electrolyte secondary batteries 1, or holes or latches that penetrate the clamping and fixing means. It is preferable to provide a locking portion that engages.

Further, in the above embodiment, the case where the assembled battery is constituted by combining a plurality of the non-aqueous electrolyte secondary batteries 1 has been described, but if the number of the non-aqueous electrolyte secondary batteries 1 is at least one, The present invention can be implemented. Further, in the above embodiment, the assembled battery in which the non-aqueous electrolyte secondary batteries 1 are combined is shown. However, the present invention can be similarly applied to an assembled battery using other types of batteries.

[0034]

As is apparent from the above description, according to the present invention, the batteries and modules of the assembled battery can be stably and reliably supported, and the management device is also attached to the side plate to achieve space efficiency. Can be increased.
