Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembled battery device, and more specifically, it requires a high voltage and a large current and can be used as a power source for electric vehicles, rocket control, and underwater vehicles. The present invention relates to an assembled battery device that can be manufactured and can be reduced in weight.

[0002]

2. Description of the Related Art An assembled battery device used as a power source for an electric vehicle, a rocket controller, and an underwater vehicle has a plurality of prismatic batteries arranged in a storage box. Two
Those described in Japanese Patent No. 20270 and Japanese Utility Model Laid-Open No. 61-62363 are known.

The one described in Japanese Patent Laid-Open No. 61-220270 has a concave and convex portion formed on the inner surface thereof, and a plurality of unit cells are stored in a storage box provided with a spacing plate in contact with the concave and convex portion. With this, vibration resistance and impact resistance are enhanced, and the spacing plate is prevented from rising.

Further, the one disclosed in Japanese Utility Model Laid-Open No. 61-62363 has a plurality of unit cells housed in a storage box provided with a composite spacer on the inner surface, whereby vibration resistance and impact resistance are improved. It is intended to increase the.

[0005]

SUMMARY OF THE INVENTION In the assembled battery device described in each of the above-mentioned publications, a spacer plate and a composite spacer are merely interposed, so that if the vibration resistance and the shock resistance are enhanced, the battery pack is stored. The strength of the box must also be increased, and it is difficult to reduce the weight of the storage box, and there is a problem that the spacing plate and the composite spacer rise up due to vibration, etc. When it is pasted and integrated, the rising can be prevented,
If the storage box is not made thick, there is a problem that the spacing plate and the composite spacer are distorted by the heat, vibration, and shock from the unit cells, and the spacing plate and the composite spacer are separated from the inner surface of the storage box. There is a problem that it is difficult to reduce the weight and the heat dissipation effect is not sufficient.

[0006]

In order to solve the above problems, the present invention provides an assembled battery device in which a plurality of prismatic batteries are arranged in a storage box, wherein the storage box has a plurality of through holes. And a fiber-reinforced synthetic resin layer disposed on the inner surface of the exterior plate, wherein the fiber-reinforced synthetic resin layer is fitted into a through hole of the exterior plate and integrated. is there.

[0007]

According to the present invention, since the through-hole is provided in the exterior plate and the fiber-reinforced synthetic resin layer is fitted and integrated into the through-hole, the strength of the storage box is increased and the weight thereof is reduced. Therefore, it is possible to solve the problem that the fiber-reinforced synthetic resin layer and the exterior plate are separated from each other, thereby improving vibration resistance and impact resistance.

EXAMPLES The present invention will be described below with reference to examples.

FIG. 1 is a perspective view of a storage box used in the assembled battery device of the present invention, and FIG. 2 is a perspective view of the assembled battery device of the present invention in which a plurality of rectangular batteries are arranged in the storage box.

In the storage box 1, as shown in FIG. 1, an exterior plate 10 is bent in a U shape to form both side surfaces and a bottom surface, and through holes 2 are provided in the both side surfaces and / or the bottom surface. A light alloy main body plate 11 and a light alloy end face plate 12 fitted in the front and rear U-shaped portions of the main body plate 11 and partially provided with a through hole 2; A fiber reinforced synthetic resin layer 3 is arranged on the inner surface of the plate 10,
The fiber reinforced synthetic resin layer 3 has through holes 2 in the exterior plate 10.
It is designed to be inserted into and integrated with.

The fiber reinforced synthetic resin layer 3 may be formed by applying an epoxy resin containing glass powder and glass flakes to the inner surface of the exterior plate 10 to enhance the vibration resistance and impact resistance of the storage box 1. For that purpose, it is necessary to make the bending elastic strength of the fiber reinforced synthetic resin layer 3 larger than the bending elastic strength of the exterior plate 10.

The epoxy resin containing glass powder and glass flakes is used as the through hole 2 of the exterior plate 10.
Apply from the outer surface to fill the gap.

A plurality of prismatic batteries 4 are arranged in such a storage box 1 to form an assembled battery device of the present invention as shown in FIG.

The thickness of the fiber reinforced synthetic resin layer 3 can be determined according to the vibration resistance and impact resistance required for the prismatic batteries to be arranged. A plurality of glass cloths impregnated with an epoxy resin are laminated on the surface of 3 to form a glass fiber reinforced resin layer, or a plurality of aromatic polyamide fiber sheets impregnated with an epoxy resin are laminated to form an aromatic polyamide fiber. A reinforced resin layer is formed, a carbon fiber reinforced resin layer is formed by laminating a plurality of carbon fiber sheets impregnated with an epoxy resin, and a rubber layer for cushioning the rectangular battery 4 is reinforced with the glass fiber. It may be provided on the surface of the resin layer or the aromatic polyamide fiber reinforced resin layer.

In the above-mentioned assembled battery device of the present invention, by using the storage box in which the fiber reinforced synthetic resin layer 3 having the strength comparable to metal is inserted into the through hole 2 of the light alloy exterior plate 10, It can be made lightweight and excellent in vibration resistance and impact resistance, can prevent peeling of the fiber reinforced synthetic resin layer 3, and can also enhance the heat radiation effect during large current discharge.
