Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery holder for holding a plurality of sealed batteries collectively. 2. Description of the Related Art A conventional battery holder is disclosed in, for example,
As described in Japanese Patent Application Laid-Open No. 222752, a plurality of cylindrical batteries are arranged so that their peripheral sides are adjacent to each other, the periphery is surrounded by a frame, and both positive and negative electrodes of each cylindrical battery are exposed. With a lid attached. The frame body includes a side wall surrounding the periphery and a number of partition walls protruding inward from the side wall. Each cylindrical battery is inserted and supported between the side walls and the partition walls. Also, a plurality of holes are drilled in the block-shaped frame, and a cylindrical battery is inserted into each hole, or a large hole formed by connecting these holes to each other is drilled. In some cases, cylindrical batteries may be fitted at once. In the lid, an elastic connection plate is appropriately arranged on a surface of the cylindrical battery facing the positive and negative electrodes of the cylindrical battery, so as to connect the cylindrical batteries.
Further, as described in Japanese Utility Model Application Laid-Open No. 2-99561, a plurality of battery cell storage sections formed so as to store a plurality of battery cells as one unit by a case outer wall and a case partition wall. A battery box has been proposed in which a plurality of battery cells are formed and a stay is provided at a central portion of the plurality of battery cells housed in the battery cell storage section, and the plurality of battery cells are tightly fixed to a partition wall. I have. [0003] When a battery is discharged, heat is generated by an internal chemical reaction. In particular, when a large current is taken out, the amount of heat generated increases. In the case of a sealed secondary battery such as a nickel cadmium battery or a nickel hydride battery, heat is generated even during charging. However, when the temperature of the battery becomes high due to these heats, the battery capacity may be reduced or the battery life may be shortened due to self-discharge. Therefore, the temperature at the time of use of the battery is determined to be within a predetermined temperature range such as -10 ° C to 60 ° C during discharge and 0 ° C to 35 ° C during charge in a normal nickel cadmium battery or the like. ing. In the case of a lead-acid battery, 0 ° C to 4 ° C
It is desirable to perform charging and discharging at 0 ° C. However, the conventional battery holder described above is
Since the periphery of the cylindrical battery was surrounded by a frame or case and both ends were covered with a lid to make the inside substantially sealed, the heat generated from the cylindrical battery during discharging or charging was sufficiently transmitted to the outside. There is a problem in that the battery cannot be discharged and the temperature of the cylindrical battery may rise beyond a specified range. Also, if the battery pack is held vertically by the battery holder, a large spatial space is required. Therefore, a plurality of batteries are held by the battery holder to form a battery pack. They may be used side by side in many directions. When connecting the assembled battery to the assembled battery, it is necessary to surely connect the connecting portion connecting one current collecting terminal to the other current collecting terminal so as not to be short-circuited. Further, when connecting these assembled batteries to each other, it is required that the assembled batteries be connected so as to have as little influence as possible on vibration and shaking. In addition, such a problem is not limited to a cylindrical battery, but is common to sealed batteries of other shapes such as a square battery. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to hold both ends of a sealed battery with a support, and to arrange a large number of batteries in a horizontal state. Provided is a battery holder that can be connected while reliably preventing a short circuit when connecting a large number of assembled batteries, is advantageous in terms of space, and can quickly release heat generated from a sealed battery to the outside. It is intended to be. [0006] The invention made to solve the above-mentioned problem is a plate-like support, one of which is sandwiched by one surface of the support by the support. A battery holder comprising a support, provided with a plurality of projecting pieces for supporting one end side of the sealed battery. Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the battery holder of the present invention. This battery holder is made of, for example, a support 2 that holds one of the sealed batteries, and is manufactured by injection molding a flame-retardant and insulating synthetic resin (for example, ABS). When holding the battery, one of the batteries is held by the support 2, and the other is held by a support 2 ′ described later, which is a slightly deformed version of the support 2. FIG. 2A is a perspective view of the battery held by the battery holder according to the present invention, as viewed from the side having terminals.
(B) is a perspective view seen from the side without terminals. As the battery, a sealed secondary battery such as a lead storage battery, a nickel cadmium battery, or a nickel metal hydride battery is used, but is not limited thereto. The cylindrical battery 1 has a lid 11 on the side having terminals.
A positive electrode terminal 1a and a negative electrode terminal 1b are attached to the first terminal. As shown in FIG. 1, the support body 2 often has a columnar shape such as a column.
(The number is not limited) is provided, and the diameter of the cylindrical portion 12 of the cylindrical battery 1 is the same as that of the four protruding pieces 2b (hatched in the figure, the number is not limited, but preferably three or more). A battery housing portion 2a having a diameter or a slightly large diameter is formed. The other support 2 'has a battery housing 2 provided at opposite ends of the support 2 respectively.
A is provided with a protruding piece 2b like the other battery storage section 2a (see FIGS. 3 and 4). Further, the support 2 'may be provided with a groove 3 so as to connect the terminals 1a and 1b of the cylindrical battery 1 as shown in FIG. Terminal 1 of cylindrical battery 1
As for the connection between a and 1b, the terminals 1a and 1b can be bolt-shaped, and a flat connection plate (not shown) can be fixed with a nut (not shown). Alternatively, the cylindrical battery 1 can be connected by embedding a conductor in the support 2 'and fitting the terminals 1a and 1b to the support 2'. In any case, FIG. 5 is an example, and the connection form and method are not limited to the method shown in FIG. Further, in the supports 2 and 2 ', the battery housing 2a
It is also possible to provide a ventilation hole penetrating from the partial surface to the back side. FIG. 3 is a perspective view showing a state where the battery 1 is held by the support 2 and the support 2 '. The support 2 and the support 2 'are arranged so that the surfaces on which the battery housings 2a and 2a are provided face each other. Then, the cylindrical portions of the six cylindrical batteries 1 on the positive and negative electrode sides are
2 ′ is fitted into each battery storage section 2a. FIG. 4 is a front view showing a state in which six batteries 1 are held between the support 2 and the support 2 '. As shown in this figure, six cylindrical batteries 1 are sandwiched between upper and lower supports 2 and 2 ′, and a current collecting terminal 1 of each cylindrical battery 1.
Reference numerals a and 1b are connected one after another by a connection plate (not shown) that extends over a groove 3 provided between the battery housing portions 2a and 2a. In this case, on the back surface side (upward surface side) of the support 2 ′, a flat connecting plate 3 made of a conductor is bridged between the adjacent current collecting terminals 1 a and 1 b to form the bolt-shaped terminals 1 a and 1 b. It is screwed with a nut (not shown). In this way, 6
The battery holder holding the cylindrical batteries 1 comes into contact with the respective supports 2 and 2 ′ on the surface, whereby the air permeability of the cylindrical batteries 1 is improved, and the heat generated from the cylindrical batteries 1 is removed. It can be released quickly to the outside. In addition, the peripheral side facing the outside of the cylindrical battery 1 has upper and lower supports 2, 2.
Since it is exposed to the outside as it is between 2 ′, heat can be released from here as well. Thus, the cylindrical battery 1
Of the cylindrical battery 1 can be suppressed so as not to exceed a predetermined range. In addition to the case of natural convection, the ventilation may be such that ventilation is forcibly performed using a fan or the like, especially when the amount of generated heat is large. In the embodiment of the present invention, a battery holder for holding six cylindrical batteries 1 has been described, but the number of cylindrical batteries 1 is arbitrary. At this time, each support 2
The projecting pieces 2b, the battery storage sections 2a, and the like can be appropriately provided according to the number and arrangement of the cylindrical batteries 1. The shape and height of the protruding piece 2b are matters relating to the design. EXAMPLE A cylindrical lead-acid battery provided with a winding type power generating element was used as a test battery. The positive electrode plate is formed by punching a lead-2% tin alloy sheet having a thickness of 0.6 mm into a current collector having a height of 90 mm and a length of 500 mm provided with openings and current collecting ears. What filled the active material which kneaded with sulfuric acid etc. was used. The negative electrode plate has a height of 90 mm provided with openings and current collecting ears by punching a 0.6 mm thick lead sheet.
A current collector having a length of 500 mm filled with an active material obtained by kneading lead powder and carbon, lignin sulfonic acid and dilute sulfuric acid, or the like was used. The positive / negative electrode plate is a band-shaped liquid-absorbing separator (0.9 mm thick) made of glass fibers of several μm.
To form a power generating element. After inserting this power generating element into a bottomed cylindrical polypropylene battery case, the lid was heat-sealed, the terminal portion was processed, and then the electrolyte was injected and charged. After injecting the electrolyte, the battery case made of polypropylene was further inserted into a bottomed cylindrical metal case to obtain a complete battery. The rating of this complete battery is 10 Ah / 5 hR-2V. [0015] The test battery was assembled by combining six test batteries. The support having no terminals of the tested battery pack was made of ABS (acrylonitrile, butadiene, styrene copolymer) and had the shape shown in FIG. As shown in FIG. 5, the support on the side where the terminals of the cylindrical battery were provided was provided with two holes through which the terminals could pass as shown in FIG. The comparative product is the protruding piece 2b shown in FIG.
, And a support in which the battery accommodating portion 2a is substantially the same as or slightly larger than the outer shape of the battery and is recessed in a concave shape is used. In each of the battery pack according to the present invention and the battery pack to be compared, the four corners of the support were fixed to each other with pillars in order to solidify the support. The number of test batteries was 10 each. The test conditions were a discharge of 1 CA (10 A) up to 1.2 V / cell (7.2 V / 6 cells), and a charge of 9 discharge currents.
0% was first charged at a constant current of 0.3 C (3 A), and then 20% of the discharged electricity was charged at a constant current of 0.05 CA (0.5 A). The life judgment condition is that the discharge duration is 2
The time was set to 0 minutes or less. The test temperature was 40 ° C. in the gas phase. The test results are shown in FIG. FIG. 6 shows the average value of 10 test batteries, the one indicated by the solid line is the product of the present invention, and the one indicated by the dotted line is the comparison product. The life of the comparative product was reached in about 300 cycles. The cause of this life was almost always a short circuit at the bottom of the cylindrical battery. In contrast, the product of the present invention reached its life in about 500 cycles. Most of the life was caused by softening of the active material. The upper part of the cylindrical lead-acid battery provided with the wound power generating element has a pole portion connected from the power generating element to the terminal, and is a portion which is hardly affected by the heat generated by the battery. The support on the side with the terminal was made the same as that of the comparative product, and the support on the side without the terminal was made the product of the present invention, and showed almost the same performance as the product of the present invention. As described in detail above, according to the battery holder of the present invention, a large number of batteries are held by a support and are installed horizontally, for example, a battery for an electric vehicle. It can be installed without taking up large space on the floor. In addition, as an assembled battery holding a plurality of batteries,
A large number of such assembled batteries can be installed in the horizontal direction. Further, in the battery holder of the present invention, heat generated from each cylindrical battery can be released to the outside through the ventilation hole of each support and the side exposed portion between the upper and lower supports, so that natural convection or forced ventilation can be used. , The temperature rise of these cylindrical batteries can be suppressed. Furthermore, when a battery holder holding a cylindrical battery with a pair of supports is laid on the floor, heat can be released to the outside through a concave groove between the support and the floor, so that many cylindrical batteries are densely packed. Even if it is performed, the temperature rise can be reliably suppressed.
