Description

本発明は、集合電池のエンドプレートに関する。   The present invention relates to an end plate of an assembled battery.

従来、この種の集合電池としては、金属製のエンドプレートを用いるものが提案されている（例えば、特許文献１など）。この集合電池では、単電池を複数積層した両積層端に金属製のエンドプレートを配置し、拘束バンドを用いて拘束して電池パックを構成している。   Conventionally, as this type of assembled battery, a battery using a metal end plate has been proposed (for example, Patent Document 1). In this collective battery, a metal end plate is disposed at both stacked ends where a plurality of unit cells are stacked, and is restrained using a restraining band to constitute a battery pack.

特開平１１−１２０９６９号公報JP-A-11-120969

しかしながら、こうした集合電池では、金属の熱伝導率の高さのためにエンドプレート近傍に配置された単電池は、外気の影響を受けやすく、他の単電池との温度の均一化を図るのが困難であった。また、エンドプレートに当接する単電池は、エンドプレートと単電池間に冷却媒体の流路の形成が困難なために、充放電の際に他の単電池より高温になりやすい場合も生じる。さらに、エンドプレートを金属により形成するから重量化してしまう。   However, in such an assembled battery, the unit cell disposed near the end plate is easily affected by the outside air due to the high thermal conductivity of the metal, and the temperature of the unit cell is made uniform with other unit cells. It was difficult. Moreover, since it is difficult to form a flow path for the cooling medium between the end plate and the single cell, the single cell that contacts the end plate may be likely to be hotter than other single cells during charging and discharging. Furthermore, since the end plate is made of metal, the weight is increased.

本発明の集合電池のエンドプレートは、エンドプレート近傍に配置された単電池の外気の影響を少なくすることを目的の一つとする。また、本発明の集合電池のエンドプレートは、当接する単電池の冷却性能を向上させることを目的の一つとする。さらに、本発明の集合電池のエンドプレートは、軽量化を図ることを目的の一つとする。本発明の集合電池のエンドプレートは、単電池の交換などのメンテナンスの容易化を図ることを目的の一つとする。   One object of the end plate of the assembled battery of the present invention is to reduce the influence of the outside air of the unit cells arranged in the vicinity of the end plate. Another object of the end plate of the assembled battery according to the present invention is to improve the cooling performance of the abutting unit cell. Furthermore, the end plate of the battery assembly of the present invention is one of the purposes for reducing the weight. One object of the end plate of the battery assembly of the present invention is to facilitate maintenance such as replacement of a unit cell.

本発明の集合電池のエンドプレートは、上述の目的の少なくとも一部を達成するために以下の手段を採った。   The end plate of the assembled battery of the present invention has taken the following means in order to achieve at least a part of the above-described object.

本発明の集合電池のエンドプレートは、集合電池を構成する際に各単電池を拘束するための少なくとも一つの拘束孔が形成され、剛性の高い材料により形成され前記拘束孔に装着されるカラーを備えるものとすることを要旨とする。   The end plate of the assembled battery according to the present invention is formed with at least one restraining hole for restraining each unit cell when forming the assembled battery, and is formed of a highly rigid material and has a collar attached to the restraining hole. The gist is to provide it.

こうした本発明の集合電池のエンドプレートにおいて、積層された単電池に当接する面に冷却媒体の流路を形成する複数のリブが形成されてなるものとすることもできる。   In the end plate of the assembled battery of the present invention, a plurality of ribs that form flow paths for the cooling medium may be formed on the surface that contacts the stacked unit cells.

こうした本発明の集合電池のエンドプレートにおいて、前記複数のリブは、一方向に平行に略等間隔に配列されてなるものとすることもできる。   In the end plate of the assembled battery according to the present invention, the plurality of ribs may be arranged in parallel with one direction at substantially equal intervals.

これら各態様を含め本発明の集合電池のエンドプレートにおいて、樹脂により形成されてなるものとすることもできる。   In addition to these embodiments, the end plate of the battery assembly of the present invention may be formed of a resin.

上記のように本発明の集合電池のエンドプレートによれば、メンテナンスの容易化を図ることができる。   As described above, according to the end plate of the battery assembly of the present invention, it is possible to facilitate maintenance.

次に、本発明の実施の形態を実施例を用いて説明する。図１は本発明の一実施例である集合電池のエンドプレート２０を当接面２２側から見た斜視図であり、図２は図１の実施例のエンドプレート２０を裏面である非当接面３２側から見た斜視図であり、図３は図１の実施例のエンドプレート２０のＡ−Ａ断面を示す断面図である。   Next, embodiments of the present invention will be described using examples. 1 is a perspective view of an end plate 20 of an assembled battery according to an embodiment of the present invention as viewed from the contact surface 22 side, and FIG. 2 is a non-contact view of the end plate 20 of the embodiment of FIG. 3 is a perspective view seen from the side of the surface 32, and FIG. 3 is a cross-sectional view showing an AA cross section of the end plate 20 of the embodiment of FIG.

実施例のエンドプレート２０は、図３に示すように、複数の単電池１０を複数積層して構成される集合電池５の両積層端に配置され、ガラス繊維などを混在させた樹脂により射出成形により成形されている。図１および図３に示すように、単電池１０の当接面２２の表面には単電池１０に当接させたときに単電池１０間に形成される冷却風の流路１２と同様な冷却風の流路２６を形成する平行に略等間隔に配置された複数のリブ２４が形成されており、図２および図３に示すように、非当接面３２の表面には空気による断熱部３６を形成する十字形状のリブ３４が全面に形成されている。   As shown in FIG. 3, the end plate 20 of the embodiment is disposed at both stacked ends of the assembled battery 5 formed by stacking a plurality of single cells 10 and is injection-molded with a resin mixed with glass fibers or the like. It is molded by. As shown in FIGS. 1 and 3, the surface of the contact surface 22 of the unit cell 10 is cooled in the same manner as the cooling air flow path 12 formed between the unit cells 10 when the unit cell 10 is contacted. A plurality of ribs 24 arranged in parallel at substantially equal intervals to form the air flow path 26 are formed, and as shown in FIGS. Cross-shaped ribs 34 forming 36 are formed on the entire surface.

また、実施例のエンドプレート２０の外周部には、複数の単電池１０により形成された積層体を拘束するための拘束ボルトを通す拘束孔４２ａ〜４２ｆを有するボルト取り付け部４０ａ〜４０ｆが形成されている。図４にボルト取り付け部４０ｂの拡大断面図を示す。図示するように、拘束孔４２ｂには、剛性の高い材料、例えばスチールなどの金属により形成された鍔付きの円管状のカラー５０が装着されており、カラー５０の中空部に挿入された拘束ボルト５２と拘束管５４とにより積層体を拘束できるようになっている。   Moreover, the bolt attachment part 40a-40f which has the restraint holes 42a-42f which let the restraint bolt for restraining the laminated body formed by the several cell 10 is formed in the outer peripheral part of the end plate 20 of an Example. ing. FIG. 4 shows an enlarged cross-sectional view of the bolt mounting portion 40b. As shown in the figure, a constraining bolt 42 inserted into a hollow portion of the collar 50 is fitted with a collar collar 50 with a hook formed of a material having high rigidity, for example, a metal such as steel. The laminated body can be restrained by 52 and the restraining tube 54.

以上説明した実施例のエンドプレート２０によれば、エンドプレート２０を樹脂により形成したので樹脂の断熱作用により、エンドプレート２０の近傍、特に当接して配置される単電池１０の外気の影響を少なくすることができる。また、樹脂は金属に比して軽いから、エンドプレート２０延いては集合電池５の比して軽量化を図ることができる。   According to the end plate 20 of the embodiment described above, since the end plate 20 is formed of resin, the influence of the outside air of the unit cell 10 disposed in the vicinity of the end plate 20, particularly in contact with the end plate 20 is reduced due to the heat insulating action of the resin. can do. Further, since the resin is lighter than the metal, the end plate 20 and the assembled battery 5 can be reduced in weight.

また、実施例のエンドプレート２０によれば、当接面２２に冷却風の流路２６を形成する複数のリブ２４を形成したので、エンドプレート２０に当接する単電池１０の冷却性能を向上させることができる。   Further, according to the end plate 20 of the embodiment, since the plurality of ribs 24 that form the cooling air flow paths 26 are formed on the contact surface 22, the cooling performance of the unit cell 10 that contacts the end plate 20 is improved. be able to.

さらに、実施例のエンドプレート２０によれば、非当接面３２に十字形状のリブ３４を形成したので、空気による断熱部３６の断熱作用によりエンドプレート２０の近傍、特に当接して配置される単電池１０の外気の影響を少なくすることができる。   Further, according to the end plate 20 of the embodiment, since the cross-shaped ribs 34 are formed on the non-contact surface 32, the end plate 20 is disposed in the vicinity of the end plate 20 by the heat insulating action of the heat insulating portion 36 by air. The influence of the outside air of the unit cell 10 can be reduced.

また、実施例のエンドプレート２０によれば、拘束孔４２ａ〜４２ｆに金属製のカラー５０を装着したので、かしめによる拘束が不要となり、単電池１０の交換などのメンテナンスの容易化を図ることができる。   Further, according to the end plate 20 of the embodiment, since the metal collar 50 is attached to the restraining holes 42a to 42f, restraint by caulking is not required, and maintenance such as replacement of the unit cell 10 can be facilitated. it can.

実施例のエンドプレート２０では、非当接面３２に空気による断熱部３６を形成する十字形状のリブ３４を形成したが、十字形状以外の形状、例えば断熱部３６の断面形状が矩形形状以外の多角形形状や円形形状あるいは楕円形形状などとなるようリブ３６を形成するものとしてもよい。また、実施例のエンドプレート２０では、カラー５０を金属により形成したが、拘束に耐えられる強度があれば如何なる材料により形成してもよい。   In the end plate 20 of the embodiment, the cross-shaped rib 34 that forms the heat insulating portion 36 by air is formed on the non-contact surface 32, but the shape other than the cross shape, for example, the cross-sectional shape of the heat insulating portion 36 is other than the rectangular shape. The ribs 36 may be formed so as to have a polygonal shape, a circular shape, an elliptical shape, or the like. Further, in the end plate 20 of the embodiment, the collar 50 is formed of metal, but may be formed of any material as long as it has strength to withstand restraint.

実施例のエンドプレート２０では、当接面２２に冷却風の流路２６を形成する複数のリブ２４を形成すると共に非当接面３２に空気による断熱部３６を形成する十字形状のリブ３４を形成したが、当接面２２に複数のリブ２４を形成しないものとしたり、非当接面３２に十字形状のリブ３４を形成しないものとしてもかまわない。   In the end plate 20 of the embodiment, a plurality of ribs 24 that form cooling air flow paths 26 are formed on the contact surface 22, and a cross-shaped rib 34 that forms a heat insulating portion 36 by air on the non-contact surface 32. Although formed, a plurality of ribs 24 may not be formed on the contact surface 22, or a cross-shaped rib 34 may not be formed on the non-contact surface 32.

実施例のエンドプレート２０では、拘束孔４２ａ〜４２ｆにカラー５０を装着するものとしたが、拘束孔４２ａ〜４２ｆにカラー５０を装着しないものとしても差し支えない。   In the end plate 20 of the embodiment, the collar 50 is attached to the restraining holes 42a to 42f, but the collar 50 may not be attached to the restraining holes 42a to 42f.

実施例のエンドプレート２０では、リブ３４により空気による断熱部３６を形成するものとしたが、図５の変形例のエンドプレート１２０に示すように、リブ１３４と当接したときに閉空間を形成するプレート１３５を配置するものとしてもよい。この閉空間は、空気による断熱効果のより高い断熱部１３６を形成するから、エンドプレート１２０の近傍に配置される単電池１１０の外気の影響をより少なくすることができる。しかも、プレート１３５はリブ１３４と当接して配置されるから、エンドプレート１２０の強度をより向上させることができる。なお、プレート１３５の材料として、特に導電性を有する金属や樹脂を用いれば、単電池１１０からの輻射ノイズを遮断して外部へ与える影響を抑制することができる。   In the end plate 20 of the embodiment, the heat insulating portion 36 by air is formed by the ribs 34. However, as shown in the end plate 120 of the modified example of FIG. It is good also as what arrange | positions the plate 135 to perform. Since this closed space forms a heat insulating part 136 having a higher heat insulating effect by air, the influence of the outside air of the unit cell 110 arranged in the vicinity of the end plate 120 can be further reduced. Moreover, since the plate 135 is disposed in contact with the rib 134, the strength of the end plate 120 can be further improved. In addition, if the metal and resin which have especially electroconductivity are used as a material of the plate 135, the radiation noise from the cell 110 can be interrupted | blocked and the influence given to the exterior can be suppressed.

実施例のエンドプレート２０やその変形例のエンドプレート１２０では、リブ３４により空気による断熱部３６を形成し、またはリブ１３４とプレート１３５とにより空気による断熱部１３６を形成するものとしたが、図６の変形例のエンドプレート２２０に示すように、隣接するリブ２３４間の空間（溝）に保温部材２３７（ゲル状の保温剤など）を充填してエンドプレート２２０の温度を管理するものとしてもよい。このように保温部材２３７によりエンドプレート２２０の温度を適切な状態に管理することで、単電池２１０が外気から受ける影響をより少なくすることができる。なお、リブ２３４の先端部には、保温部材２３７をリブ２３４間の空間内に保持するために、リブ２３４の先端部と当接するようにプレート２３５が配置されている。このプレート２３５は、エンドプレート２２０の強度を向上させたり、導電性を有する金属や樹脂を材料として用いたときに単電池からの輻射ノイズを遮断したりすることができるのは勿論である。また、こうした保温部材２３７に代えて、あるいは保温部材２３７と共にヒータなどを用いてエンドプレート２２０の温度を積極的に管理することも好適である。   In the end plate 20 of the embodiment and the end plate 120 of the modified example, the heat insulating portion 36 is formed by the ribs 34, or the heat insulating portion 136 is formed by the ribs 134 and the plate 135. 6, the temperature of the end plate 220 may be controlled by filling a space (groove) between adjacent ribs 234 with a heat insulating member 237 (gel-like heat insulating agent or the like). Good. In this way, by managing the temperature of the end plate 220 in an appropriate state by the heat retaining member 237, the influence of the unit cell 210 from the outside air can be further reduced. Note that a plate 235 is disposed at the tip of the rib 234 so as to contact the tip of the rib 234 in order to hold the heat retaining member 237 in the space between the ribs 234. Of course, the plate 235 can improve the strength of the end plate 220 and can block radiation noise from the unit cell when a conductive metal or resin is used as a material. It is also preferable to actively manage the temperature of the end plate 220 by using a heater or the like instead of the heat retaining member 237 or together with the heat retaining member 237.

本発明の実施の形態について実施例を用いて説明したが、本発明はこうした実施例に何等限定されるものではなく、本発明の要旨を逸脱しない範囲内において、種々なる形態で実施し得ることは勿論である。   Although the embodiments of the present invention have been described using examples, the present invention is not limited to these examples, and can be implemented in various forms without departing from the spirit of the present invention. Of course.
