Description

本発明は、複数のラミネート電池を接続してなるモジュールを固定保持するためのモジュール用筐体、および複数のモジュールを接続してなる組電池に関する。   The present invention relates to a module housing for fixing and holding a module formed by connecting a plurality of laminated batteries, and an assembled battery formed by connecting a plurality of modules.

ラミネート電池は、電池自体の剛性が低いため、モジュール化する場合、所定の個数のラミネート電池を電気的に接続して構成されたモジュール２１４の全面を覆う箱形状の筐体２００内にモジュール２１４を収納する構成が採用される場合があった（特許文献１および図１参照）。   Since the laminate battery has low rigidity, when the module is made into a module, the module 214 is placed in a box-shaped casing 200 that covers the entire surface of the module 214 configured by electrically connecting a predetermined number of laminate batteries. In some cases, a housing configuration is employed (see Patent Document 1 and FIG. 1).

モジュール化された電池は、複数のモジュール２１４が電気的に接続されて組電池化されて最終的に必要な電圧値を得ることとなるが、複数のモジュール２１４はこれらを収納可能な大型の筐体３００内に収納されて取り扱われる（図２参照）。   The modularized battery is assembled as a result of a plurality of modules 214 being electrically connected to obtain a required voltage value, but the plurality of modules 214 are large-sized housings that can accommodate them. It is stored in the body 300 and handled (see FIG. 2).

特開２００４−１４３１７号公報JP 2004-14317 A

電池を覆う箱形状のモジュール用筐体に収納した場合、単なる平面で囲まれた箱状の筐体では筐体自体の剛性が低くなる。このため、筐体の壁面にリブを設けて剛性を上げる手法が一般に採用されている。一方、電池は発熱するため、冷却風を筐体内に導入する必要があるが、リブが筐体の内壁面に設けられていると、冷却風の流れを阻害してしまい、所望の冷却特性が得られない場合がある。そこで、冷却風の流れを阻害しないようにするべくリブを覆う平滑な板部材をモジュール用筐体の壁面を追加すると、冷却風の流れに対しては好ましくなる。リブ付き壁面をさらに平滑な壁面で覆う構成は、剛性が上がり、かつ冷却風の流れを阻害しない構成とはなるものの、重量が増加してしまうとともにコストもかかる。また、組電池用筐体内の限られたスペースにリブ付き壁面をさらに平滑な壁面で覆う構成のモジュール用筐体を収納した場合、冷却風の流路断面が狭められてしまい、結局、良好な冷却特性を得ることが困難となってしまうことが考えられる。   When housed in a box-shaped module housing that covers the battery, the housing itself has low rigidity in a box-shaped housing surrounded by a simple plane. For this reason, a method of increasing the rigidity by providing ribs on the wall surface of the housing is generally employed. On the other hand, since the battery generates heat, it is necessary to introduce cooling air into the housing. However, if the rib is provided on the inner wall surface of the housing, the flow of the cooling air is obstructed, and the desired cooling characteristics are obtained. It may not be obtained. Therefore, it is preferable for the flow of cooling air to add a smooth plate member covering the ribs so as not to obstruct the flow of cooling air to the wall surface of the module housing. The configuration in which the ribbed wall surface is covered with a smoother wall surface increases the rigidity and does not hinder the flow of cooling air, but increases the weight and costs. In addition, when the module housing having a structure in which the ribbed wall surface is covered with a smoother wall surface in a limited space in the assembled battery housing, the cross-section of the cooling air flow path is narrowed, which is eventually good. It may be difficult to obtain cooling characteristics.

一方、冷却用の流路断面を確保するため、モジュール用筐体を用いずに電池を組電池用筐体に直接搭載する方式は、複数の電池を搭載する際、その取扱いが煩雑となってしまう。   On the other hand, in order to secure the cross section of the flow path for cooling, the method of directly mounting the battery on the assembled battery housing without using the module housing makes the handling complicated when mounting a plurality of batteries. End up.

そこで、本発明は、高剛性、冷却特性良好、かつ軽量な、複数のフィルム外装電気デバイスを収納するモジュール用筐体と、それに保持された複数のフィルム外装電気デバイスを有する組電池とを提供することを目的とする。   Accordingly, the present invention provides a module housing that houses a plurality of film-clad electrical devices that is highly rigid, has good cooling characteristics, and is lightweight, and an assembled battery that has a plurality of film-clad electrical devices held by the module housing. For the purpose.

上記目的を達成するため、本発明のモジュール用筐体は、複数のフィルム外装電気デバイスと複数のフィルム外装電気デバイスを収容するケースとからなるモジュールを収容するモジュール用筐体であって、底面と、底面に立設し、底面と共に冷却路を形成する第１の側面部と、第１の側面部に接続し、モジュールを保持する保持板と、保持板に立設する第２の側面部と、第２の側面部に形成された曲げ部であって、ケースに形成された溝部と係合する曲げ部と、を有している。 To achieve the above object, the module housing of the present invention is a module housing for housing the module comprised of a plurality of film-covered electrical device and a plurality of film case for accommodating the covered electrical device, and a bottom surface A first side surface portion standing on the bottom surface and forming a cooling path with the bottom surface; a holding plate connected to the first side surface portion for holding the module; and a second side surface portion standing on the holding plate; And a bent portion formed on the second side surface portion, the bent portion engaging with the groove portion formed on the case.

本発明の組電池は、本発明のモジュール用筐体と、モジュール用筐体に保持された複数のフィルム外装電気デバイスと、有している。   The assembled battery of the present invention includes the module casing of the present invention and a plurality of film-covered electrical devices held in the module casing.

以上、本発明によれば、高剛性、冷却特性良好、かつ軽量な、複数のフィルム外装電気デバイスを収納するモジュール用筐体と、それに保持された複数のフィルム外装電気デバイスを有する組電池とを提供することことができる。   As described above, according to the present invention, a high-rigidity, good cooling characteristic, and light weight module housing that houses a plurality of film-covered electrical devices, and an assembled battery that has the plurality of film-wrapped electrical devices held therein.

[Configuration of film-clad battery]
FIG. 3 shows an external perspective view of the film-clad battery of this embodiment.

本実施形態のフィルム外装電池１は、不図示の正極側活電極、負極側活電極、および電解液を有する発電要素２と、アルミニウムなどの金属フィルムと熱融着性の樹脂フィルムとを重ね合わせて形成したラミネートフィルム７を熱融着部７ａの４辺で熱融着して密封した構造を有している。   The film-clad battery 1 according to this embodiment includes a power generation element 2 having a positive electrode side active electrode, a negative electrode side active electrode, and an electrolyte solution (not shown), a metal film such as aluminum, and a heat-fusible resin film. The laminate film 7 formed in this way has a structure in which the four sides of the heat-sealed portion 7a are heat-sealed and sealed.

フィルム外装電池１の発電要素２は、不図示のセパレータを介して積層された正極側活電極と負極側活電極とからなる積層型であってもよい。あるいは、発電要素２は、帯状の正極側活電極と負極側活電極とをセパレータを介して重ねこれを捲回した後、扁平状に圧縮することによって正極側活電極と負極側活電極とが交互に積層された構造の捲回型であってもよい。   The power generation element 2 of the film-clad battery 1 may be a laminated type composed of a positive electrode side active electrode and a negative electrode side active electrode that are stacked via a separator (not shown). Alternatively, in the power generation element 2, the belt-like positive electrode side active electrode and the negative electrode side active electrode are stacked via a separator, wound, and then compressed into a flat shape, whereby the positive electrode side active electrode and the negative electrode side active electrode are A wound type having a structure in which layers are alternately stacked may be used.

また、発電要素２としては、正極、負極および電解質を含むものであれば、通常の電池に用いられる任意の発電要素が適用可能である。一般的なリチウムイオン二次電池における発電要素は、リチウム・マンガン複合酸化物、コバルト酸リチウム等の正極活物質をアルミニウム箔などの両面に塗布した正極板と、リチウムをドープ・脱ドープ可能な炭素材料を銅箔などの両面に塗布した負極板とを、セパレータを介して対向させ、それにリチウム塩を含む電解液を含浸させて形成される。発電要素２としては、この他に、ニッケル水素電池、ニッケルカドミウム電池、リチウムメタル一次電池あるいは二次電池、リチウムポリマー電池等、他の種類の化学電池の発電要素が挙げられる。さらに、本発明は、電気二重層キャパシタなどのキャパシタや電解コンデンサなどに例示されるキャパシタ要素のような、電気エネルギを内部に蓄積し化学反応または物理反応でガスが発生しうる電気デバイス要素を外装フィルムで封止した電気デバイスにも適用可能である。   In addition, as the power generation element 2, any power generation element used for a normal battery is applicable as long as it includes a positive electrode, a negative electrode, and an electrolyte. The power generation elements in a typical lithium ion secondary battery include a positive electrode plate in which a positive electrode active material such as lithium-manganese composite oxide and lithium cobaltate is applied on both sides of an aluminum foil, etc., and carbon that can be doped and dedoped with lithium. A negative electrode plate coated with a material on both sides of a copper foil or the like is opposed to each other with a separator interposed between them and impregnated with an electrolytic solution containing a lithium salt. Other examples of the power generation element 2 include power generation elements of other types of chemical batteries such as nickel metal hydride batteries, nickel cadmium batteries, lithium metal primary batteries or secondary batteries, and lithium polymer batteries. Furthermore, the present invention provides an external device that stores electrical energy and generates gas by chemical reaction or physical reaction, such as a capacitor element exemplified by a capacitor such as an electric double layer capacitor and an electrolytic capacitor. The present invention can also be applied to an electric device sealed with a film.

フィルム外装電池１は、短手方向の熱融着部７ａから、正極側活電極に接続された正極用電極端子３および負極側活電極に接続された負極用電極端子４がそれぞれ対向して延出している。正極用電極端子３としてはアルミニウムが多く用いられる。また、負極用電極端子４としては銅またはニッケルがその電気的特性により多く用いられている。以下、正極用電極端子３と負極用電極端子４とをまとめて単に電極と称する場合もある。   In the film-clad battery 1, the positive electrode terminal 3 connected to the positive electrode side active electrode and the negative electrode terminal 4 connected to the negative electrode side active electrode respectively extend from the heat-sealing portion 7a in the short direction. I'm out. As the positive electrode terminal 3, aluminum is often used. Further, copper or nickel is often used as the negative electrode terminal 4 due to its electrical characteristics. Hereinafter, the positive electrode terminal 3 and the negative electrode terminal 4 may be collectively referred to as electrodes.

複数のフィルム外装電池１は、図４に示すセルケース１０に収納された状態で積層されてモジュール化される。   The plurality of film-clad batteries 1 are stacked and modularized in a state of being housed in the cell case 10 shown in FIG.

フィルム外装電池１の周囲を囲むセルケース１０は、フィルム外装電池１の熱融着部７ａを挟持する。セルケース１０の形状は枠状であり、発電要素２に対応した箇所に開口１５が形成されている。セルケース１０の短手方向には溝１１が形成されている。セルケースを積層してモジュール１４とすることで各溝１１は、積層方向に延びた位置決めスリット１２を形成する。この位置決めスリット１２は、後述するモジュール用筐体２０の曲げ端４１を差し込むためのものである。また、セルケース１０の長手面１０ａ側には発電要素２を冷却するための冷却風を通風させるための開口部１６が形成されている。   A cell case 10 surrounding the film-covered battery 1 sandwiches the heat-sealing portion 7a of the film-covered battery 1. The cell case 10 has a frame shape, and an opening 15 is formed at a location corresponding to the power generation element 2. Grooves 11 are formed in the short direction of the cell case 10. By stacking the cell cases into the module 14, each groove 11 forms a positioning slit 12 extending in the stacking direction. The positioning slit 12 is for inserting a bent end 41 of the module housing 20 described later. In addition, an opening 16 for allowing cooling air to cool the power generation element 2 is formed on the longitudinal surface 10 a side of the cell case 10.

［モジュール用筐体］
図５Ａに、本実施形態のモジュール用筐体をモジュールに取り付けた状態の斜視図を、図５Ｂに、モジュールに対するモジュール用筐体の組み付け方法を示す。なお、図５においては、セルケース１０およびフィルム外装電池１は簡略化されて示されている。 [Module housing]
FIG. 5A shows a perspective view of the module housing of this embodiment attached to the module, and FIG. 5B shows a method of assembling the module housing to the module. In FIG. 5, the cell case 10 and the film-clad battery 1 are shown in a simplified manner.

モジュール用筐体２０は、モジュール１４を支持する支持部４０と、モジュール１４を冷却する冷却風を流すクーリングダクト３０とを有する。   The module housing 20 includes a support portion 40 that supports the module 14 and a cooling duct 30 that flows cooling air that cools the module 14.

支持部４０は、セルケース１０の長手方向の両端部を保持する保持面４２と、保持面４２の一端から立ち上がった側面４３と、側面４３の端部を折り曲げた曲げ端４１と、モジュール用筐体２０に組みつけられたモジュール１４を突き当てて固定する突当部４４と、突当部４４と対向する側からモジュール１４を固定するＬ字形状の固定金具４５とを有する。   The support portion 40 includes a holding surface 42 that holds both ends of the cell case 10 in the longitudinal direction, a side surface 43 that rises from one end of the holding surface 42, a bent end 41 that is a bent end portion of the side surface 43, and a module housing. The abutting portion 44 abuts and fixes the module 14 assembled to the body 20, and an L-shaped fixing bracket 45 that fixes the module 14 from the side facing the abutting portion 44.

保持面４２、側面４３および曲げ端４１は、突当部４４の両側に対向するように形成されており、固定金具４５が組みつけられることで枠形状となる。すなわち、本実施形態においては、支持部４０は、２つの保持面４２と、３つの側面４３および固定金具４５を含む側面部分とからなる枠形状となっている。   The holding surface 42, the side surface 43, and the bent end 41 are formed so as to face both sides of the abutting portion 44, and have a frame shape when the fixing bracket 45 is assembled. That is, in the present embodiment, the support portion 40 has a frame shape including two holding surfaces 42 and side portions including the three side surfaces 43 and the fixing bracket 45.

クーリングダクト３０は支持部４０の下部に一体的に設けられている。クーリングダクト３０は、支持部４０の各保持面４２の他端から下方に連続的に延びたダクト側面３１と、各ダクト側面３１を繋ぐダクト底面３２と、突当部４４の下方に設けられたダクト端面３３と、ダクト端面３３に対向する側に形成された開口部３４とを有する。各ダクト側面３１間の幅は、支持部４０の側面４３間の幅より保持面４２の分だけ狭くなっている。クーリングダクト３０におけるダクト側面部は２つのダクト側面３１と１つのダクト端面３３とを含むものとなる。なお、支持部４０の突当部４４とクーリングダクト３０のダクト端面３３は連続した一枚の板として構成されてもよいが、突当部４４とダクト端面３３との間に保持面４２が形成された階段形状とし、剛性を高めた形状としてもよい。   The cooling duct 30 is integrally provided at the lower portion of the support portion 40. The cooling duct 30 is provided below a duct side surface 31 that continuously extends downward from the other end of each holding surface 42 of the support portion 40, a duct bottom surface 32 that connects each duct side surface 31, and a lower portion 44. It has a duct end surface 33 and an opening 34 formed on the side facing the duct end surface 33. The width between the duct side surfaces 31 is narrower by the holding surface 42 than the width between the side surfaces 43 of the support portion 40. The duct side surface portion in the cooling duct 30 includes two duct side surfaces 31 and one duct end surface 33. The abutting portion 44 of the support portion 40 and the duct end surface 33 of the cooling duct 30 may be configured as a single continuous plate, but a holding surface 42 is formed between the abutting portion 44 and the duct end surface 33. It is good also as the shape which was made the step shape made, and the shape which raised rigidity.

モジュール用筐体２０は、ダクト底面３２に対向する側に開口部を有し、また、クーリングダクト３０に冷却風を導入するための開口部３４が形成されている。しかしながら、本実施形態のモジュール用筐体２０は、側面４３、保持面４２およびダクト側面３１を折り曲げてなる断面形状を有すること、各側面４３は突当部４４により互いに繋げられ、各ダクト側面３１はダクト底面３２およびダクト端面３３で互いに繋げられていることで高い剛性を有する。すなわち、クーリングダクト３０は、冷却風を通風させる機能の他、支持部４０の剛性を高めるための剛性部材として機能している。さらに、モジュール用筐体２０は、補強部材としても機能する固定金具４５を取り付けた状態で枠形状となるため、高い剛性を有する。なお、モジュール用筐体２０は、その各隅部等に補強部材を追加する、端部を折り曲げ加工する等により、さらに剛性を高めることも可能である。   The module housing 20 has an opening on the side facing the duct bottom surface 32, and an opening 34 for introducing cooling air into the cooling duct 30 is formed. However, the module housing 20 of the present embodiment has a cross-sectional shape formed by bending the side surface 43, the holding surface 42, and the duct side surface 31, and the side surfaces 43 are connected to each other by the abutting portion 44. Are connected to each other at the duct bottom surface 32 and the duct end surface 33 and have high rigidity. That is, the cooling duct 30 functions as a rigid member for increasing the rigidity of the support portion 40 in addition to the function of passing cooling air. Furthermore, the module housing 20 has a high rigidity because it has a frame shape with the fixing bracket 45 that also functions as a reinforcing member attached. The module housing 20 can be further enhanced in rigidity by adding a reinforcing member to each corner or the like, or bending the end.

次に、モジュール１４のモジュール用筐体２０への組み付けについて説明する。   Next, assembly of the module 14 to the module housing 20 will be described.

図５Ｂに示すように、モジュール１４を、モジュール用筐体２０の開口部３４が形成された側から矢印Ａ方向に位置決めスリット１２を曲げ端４１にあわせるようにして差し込む。   As shown in FIG. 5B, the module 14 is inserted so that the positioning slit 12 is aligned with the bending end 41 in the direction of arrow A from the side where the opening 34 of the module housing 20 is formed.

モジュール用筐体２０に差し込まれたモジュール１４を、第１のモジュール端面１４ａが突当部４４に突き当たるまで、支持部４０の保持面４２上を、セルケース１０の長手面１０ａを滑り込ませる。   The long surface 10 a of the cell case 10 is slid on the holding surface 42 of the support portion 40 until the first module end surface 14 a abuts against the abutting portion 44.

突当部４４に第１のモジュール端面１４ａに突き当てた状態で、開口部３４側、すなわち、突当部４４の反対側から固定金具４５を第２のモジュール端面１４ｂへと矢印ａ方向に押し当てる。最後に、保持面４２に形成されたネジ穴４２ａと固定金具４５に形成されたネジ穴４５ａとを位置合わせし、ネジを螺入することでモジュール１４をモジュール用筐体２０へと固定する。なお、位置決めスリット１２に曲げ端４１が差し込まれていることで図５Ａ中、矢印Ｂ方向にモジュール１４が抜けることはない。   With the abutting portion 44 abutting against the first module end surface 14a, the fixing bracket 45 is pushed toward the second module end surface 14b in the direction of arrow a from the opening 34 side, that is, the opposite side of the abutting portion 44. Hit it. Finally, the screw hole 42a formed in the holding surface 42 and the screw hole 45a formed in the fixing bracket 45 are aligned, and the module 14 is fixed to the module housing 20 by screwing the screw. Note that the module 14 does not come out in the direction of arrow B in FIG. 5A because the bending end 41 is inserted into the positioning slit 12.

モジュール１４は、その長手面１０ａ側が、枠形状で、かつクーリングダクト３０を剛性部材として共用しているモジュール用筐体２０によって固定保持される。すなわち、モジュール用筐体２０はモジュール１４を全体的に覆う構成となっていないため、全体を覆う構成のモジュールケースと比較して軽量化が図られている。また、本実施形態のモジュール用筐体２０は上述したように剛性を高めるために枠形状としているので、モジュール１４をしっかりと固定保持することができる。   The module 14 is fixedly held by a module housing 20 having a frame shape on the longitudinal surface 10a side and sharing the cooling duct 30 as a rigid member. That is, since the module housing 20 is not configured to cover the module 14 as a whole, the module casing 20 is lighter than a module case configured to cover the entire module. In addition, since the module housing 20 of the present embodiment has a frame shape in order to increase rigidity as described above, the module 14 can be firmly fixed and held.

以上、本実施形態のモジュール用筐体２０は、モジュール１４を保持する枠形状の支持部４０にフィルム外装電池１を冷却するためのクーリングダクト３０を一体的に設けた構成となっているため、クーリングダクト３０を冷却風の流路としてのみならず剛性部材として機能させることができる。これにより、クーリングダクトと支持部とが一体的でなく別々に設けられた構成に比べて高剛性とすることができる。また、クーリングダクト３０自体の剛性も支持部４０が一体的に設けられていることで高められている。すなわち、本実施形態のモジュール用筐体２０は、リブ等をダクト壁面に設ける必要がないので、ダクトの流路断面を狭めることもなく、ダクト内の冷却風の流れをリブが阻害するといったこともない。よって、本実施形態のモジュール用筐体２０は、ダクト内壁にリブを備えて剛性を高めた構成のものに比べて冷却特性を向上させることができる。さらに、本実施形態のモジュール用筐体２０は、リブが不要であることから、このリブを覆う整流板を設ける必要もないので軽量となる。さらに、支持部４０は枠形状であり、モジュール１４全体を覆う箱形状ではないため、箱形状のものに比べて軽量化が図られている。   As described above, the module housing 20 of the present embodiment has a configuration in which the cooling duct 30 for cooling the film-clad battery 1 is integrally provided on the frame-shaped support portion 40 that holds the module 14. The cooling duct 30 can function not only as a cooling air flow path but also as a rigid member. Thereby, it can be set as high rigidity compared with the structure with which the cooling duct and the support part were not integrated, and were provided separately. In addition, the rigidity of the cooling duct 30 itself is enhanced by the support portion 40 being integrally provided. That is, the module housing 20 of the present embodiment does not require a rib or the like to be provided on the duct wall surface, so that the rib blocks the flow of cooling air in the duct without narrowing the cross section of the duct. Nor. Therefore, the module housing 20 of the present embodiment can improve the cooling characteristics as compared with the configuration in which the rib is provided on the inner wall of the duct and the rigidity is increased. Furthermore, since the module housing 20 of the present embodiment does not require a rib, there is no need to provide a rectifying plate that covers the rib, and thus the weight is light. Furthermore, since the support portion 40 has a frame shape and is not a box shape that covers the entire module 14, the weight is reduced compared to the box shape.

［組電池化および組電池の冷却方法］
次に、複数のモジュール１４を接続して構成する組電池化および組電池の冷却方法について図６を用いて説明する。 [Method of battery assembly and battery cooling]
Next, an assembled battery configured by connecting a plurality of modules 14 and a method for cooling the assembled battery will be described with reference to FIG.

図６には２つのモジュール１４を接続して組電池化した例を示している。図中左側のモジュール１４はセルケース１０を省略して示しており、図中右側のモジュール１４についてはセルケースから延出した電極を隣接したフィルム外装電池１の電極とが接続された様子を示している。   FIG. 6 shows an example in which two modules 14 are connected to form an assembled battery. The module 14 on the left side in the figure shows the cell case 10 omitted, and the module 14 on the right side in the figure shows a state in which the electrodes extending from the cell case are connected to the electrodes of the film-clad battery 1 adjacent to each other. ing.

まず、モジュール用筐体２０に取り付けられたモジュール１４を並べてモジュール用筐体２０同士を接合する。なお、モジュール用筐体２０同士の接合の詳細については後述する。   First, the modules 14 attached to the module housing 20 are arranged and the module housings 20 are joined to each other. Details of the joining of the module casings 20 will be described later.

接合されたモジュール用筐体２０の周辺、すなわち、各隅部および中央部に接合ロッド５０の一端を取り付ける。上部クーリングダクト６０を接合ロッド５０の他端に取り付ける。これにより、組電池化された各モジュール用筐体２０の下側をモジュール用筐体２０で覆い、上側を上部クーリングダクト６０で覆った組電池筐体が構成される。なお、接合ロッド５０による上部クーリングダクト６０とモジュール用筐体２０との接合は接合ロッド５０の両端部にネジ穴を設けておき、このネジ穴を用いてネジにより上部クーリングダクト６０およびモジュール用筐体２０にネジ留めしてもよい。   One end of the joining rod 50 is attached to the periphery of the joined module case 20, that is, each corner and center. The upper cooling duct 60 is attached to the other end of the joining rod 50. As a result, an assembled battery case is formed in which the lower side of each module case 20 formed into an assembled battery is covered with the module case 20 and the upper side is covered with the upper cooling duct 60. For joining the upper cooling duct 60 and the module housing 20 by the joining rod 50, screw holes are provided at both ends of the joining rod 50, and the upper cooling duct 60 and the module housing are screwed by using the screw holes. It may be screwed to the body 20.

冷却風用の冷却路は、クーリングダクト３０、セルケース１０間の開口部１６、隣接する発電要素２、上部クーリングダクト６０で構成される。冷却風は開口部３４から導入され、クーリングダクト３０内を流れて図６中矢印Ｃで示すようにセルケース１０間の開口部１６へと流れ込む。セルケース１０間の開口部１６から流れ込んだ冷却風はフィルム外装電池１の発電要素２部分を冷却しながらセルケース１０の反対側の開口部１６から矢印Ｄで示すように上部クーリングダクト６０内へと流れ出る。上部クーリングダクト６０内を流れた冷却風は上部クーリングダクト６０の端部に設けられた排出部６１より排出される。以上の構成により、冷却風は最も発熱する発電要素２の部分を効率よく冷却することができる。   The cooling path for cooling air includes a cooling duct 30, an opening 16 between the cell cases 10, an adjacent power generation element 2, and an upper cooling duct 60. The cooling air is introduced from the opening 34, flows through the cooling duct 30, and flows into the opening 16 between the cell cases 10 as indicated by an arrow C in FIG. The cooling air flowing from the opening 16 between the cell cases 10 cools the power generation element 2 portion of the film-clad battery 1 and enters the upper cooling duct 60 from the opening 16 on the opposite side of the cell case 10 as indicated by an arrow D. And flows out. Cooling air that has flowed through the upper cooling duct 60 is discharged from a discharge portion 61 provided at an end of the upper cooling duct 60. With the above configuration, the cooling air can efficiently cool the portion of the power generating element 2 that generates the most heat.

このように、モジュール用筐体２０と上部クーリングダクト６０とを接合ロッド５０で接合し、かつセルケース１０間の開口部１６を用いた構成は、モジュール１４全体を覆うことなく冷却路を構成することができる。この構成の組電池ケースは、軽量かつ冷却特性が良好となる。   As described above, the configuration in which the module housing 20 and the upper cooling duct 60 are joined by the joining rod 50 and the opening 16 between the cell cases 10 is used constitutes a cooling path without covering the entire module 14. be able to. The assembled battery case having this configuration is lightweight and has good cooling characteristics.

（第２の実施形態）
上述した実施形態ではモジュール用筐体２０は各モジュール１４毎に用意され、上部クーリングダクト６０は２つのモジュール１４に対して１つ用意する構成例を示した。これに対して本実施形態では、図７および図８に示すように、１つのモジュールに対してモジュール用筐体と上部クーリングダクトとをそれぞれ１つずつ用意する構成例について説明する。 (Second Embodiment)
In the above-described embodiment, the module casing 20 is prepared for each module 14, and one upper cooling duct 60 is prepared for the two modules 14. On the other hand, in this embodiment, as shown in FIGS. 7 and 8, a configuration example in which one module housing and one upper cooling duct are prepared for each module will be described.

本実施形態のモジュール用筐体１２０もモジュール１４を支持する支持部１４０と、剛性部材としても機能するクーリングダクト１３０とを有する点で第１の実施形態のモジュール用筐体２０と基本的には同様の構成である。しかし、第１の実施形態のモジュール用筐体２０は、保持面４２に沿ってモジュール１４を滑り込ませて最後に固定金具４５で固定する方式であったのに対し、本実施形態は、第１の実施形態の固定金具４５に相当する部分がすでに側面１４３のひとつとして支持部１４０に設けられている点で異なる。よって、モジュール用筐体１２０へのモジュール１４の取り付けはモジュール用筐体１２０の上方に向けて開口されている挿入口１２１から図中矢印Ｅ方向へ挿入することとなる。   The module housing 120 of the present embodiment is basically the same as the module housing 20 of the first embodiment in that the module housing 120 has a support portion 140 that supports the module 14 and a cooling duct 130 that also functions as a rigid member. It is the same composition. However, the module housing 20 of the first embodiment is a system in which the module 14 is slid along the holding surface 42 and is finally fixed by the fixing bracket 45, whereas this embodiment is the first A difference is that a portion corresponding to the fixing bracket 45 of the embodiment is already provided on the support portion 140 as one of the side surfaces 143. Therefore, the module 14 is attached to the module housing 120 through the insertion port 121 opened upward from the module housing 120 in the direction of arrow E in the figure.

また、第１の実施形態は、２つのモジュール１４のそれぞれの下部にモジュール用筐体２０に取り付け、これら２つのモジュール１４に対して１つの上部クーリングダクト６０を被せる構成とした。一方、本実施形態は、１つのモジュール１４の下部に１つのモジュール用筐体１２０を取り付け、このモジュール１４に、下部に取り付けたモジュール用筐体１２０と同一形状のモジュール用筐体１２０を１つ被せる構成としている。すなわち、本実施形態は、同形状のモジュール用筐体１２０でモジュール１４を挟み込み、これら二つのモジュール用筐体１２０の各隅部を接合ロッド５０で接合している。   In the first embodiment, the module module 20 is attached to the lower part of each of the two modules 14, and one upper cooling duct 60 is covered with the two modules 14. On the other hand, in the present embodiment, one module housing 120 is attached to the lower part of one module 14, and one module housing 120 having the same shape as the module housing 120 attached to the lower part is attached to the module 14. The structure is covered. That is, in this embodiment, the module 14 is sandwiched between the module casings 120 having the same shape, and the corners of the two module casings 120 are joined by the joining rods 50.

このような構成であるため本実施形態は、各モジュール１４毎に冷却路を形成することができるとともに、モジュール１４が上下方向から剛性の高められたモジュール用筐体１２０でしっかりと固定されているため、モジュール１４毎の取扱いが容易となる。   With this configuration, in the present embodiment, a cooling path can be formed for each module 14, and the module 14 is firmly fixed by a module housing 120 with increased rigidity from the vertical direction. Therefore, handling for each module 14 becomes easy.

また、本実施形態は、２つのモジュール用筐体１２０が同一形状の部品であるため、コスト面で有利である。   Further, this embodiment is advantageous in terms of cost because the two module housings 120 are parts having the same shape.

また、本実施形態のモジュール用筐体１２０も第１の実施形態のモジュール用筐体２０と同様に、高剛性、軽量、かつ良好な冷却特性を有する。   The module housing 120 of the present embodiment also has high rigidity, light weight, and good cooling characteristics, like the module housing 20 of the first embodiment.

［モジュール用筐体同士の接合］
次に、モジュール用筐体同士の接合について図９Ａおよび図９Ｂを用いて説明する。なお、説明に用いる符号は第１の実施形態で用いた符号を用いる。 [Bonding module housings]
Next, joining of module housings will be described with reference to FIGS. 9A and 9B. In addition, the code | symbol used for description uses the code | symbol used in 1st Embodiment.

図９Ａでは２つのモジュール用筐体２０ａ、２０ｂが接合されている。モジュール用筐体２０ｂにはダクト端面３０が設けられているが、モジュール用筐体２０ａはダクト端面３０が設けられておらず開口している。すなわち、モジュール用筐体２０ａは開口部３４と、これに対面する側にも開口が形成されている。このような構成であるため、モジュール用筐体２０ａ、２０ｂが接合されることでモジュール用筐体２０ａのクーリングダクト３０とモジュール用筐体２０ｂのクーリングダクト３０とが連通することとなる。   In FIG. 9A, two module cases 20a and 20b are joined. The module casing 20b is provided with a duct end face 30, but the module casing 20a is not provided with the duct end face 30 and is open. That is, the module casing 20a has an opening 34 and an opening formed on the side facing the opening 34. Because of such a configuration, the module casings 20a and 20b are joined, so that the cooling duct 30 of the module casing 20a and the cooling duct 30 of the module casing 20b communicate with each other.

これらモジュール用筐体２０ｂの開口部３４、およびモジュール用筐体２０ａの開口部３４に対面する側の開口にはそれぞれ接合フランジ２０ｃが形成されている。図９Ａ中、Ａで示す部分を拡大した図である図９Ｂを参照すると、モジュール用筐体２０ａ、２０ｂを互いに接合は、接合フランジ２０ｃどうしを対面させ、ネジ、あるいはリベットによりなされている。   A joint flange 20c is formed in each of the opening 34 of the module housing 20b and the opening facing the opening 34 of the module housing 20a. Referring to FIG. 9B, which is an enlarged view of the portion indicated by A in FIG. 9A, the module housings 20a and 20b are joined to each other by screws or rivets with the joining flanges 20c facing each other.

さらに、モジュール１４を搭載したモジュール用筐体２０ａ、２０ｂをカバー７０にて覆う場合、カバー７０とモジュール用筐体２０ａ、２０ｂとをネジ、あるいはリベットにより接合する。すなわち、カバー７０の下端部には複数の接合穴７１が形成されており、また、モジュール用筐体２０ａ、２０ｂの側面４３にもカバー７０の接合穴７１に対応する位置に接合穴４３ａが形成されており、これらを位置あわせした後、ネジ、あるいはリベットを貫通させてカバー７０とモジュール用筐体２０ａ、２０ｂとを接合する。   Further, when the module casings 20a and 20b on which the module 14 is mounted are covered with the cover 70, the cover 70 and the module casings 20a and 20b are joined by screws or rivets. That is, a plurality of joint holes 71 are formed in the lower end portion of the cover 70, and the joint holes 43a are also formed on the side surfaces 43 of the module housings 20a and 20b at positions corresponding to the joint holes 71 of the cover 70. After these are aligned, the cover 70 and the module housings 20a and 20b are joined by passing through screws or rivets.

以上のように、モジュール用筐体２０ａ、２０ｂ同士直接接合するのみならず、カバー７０によっても両者を接合することでより確実な接合がなされる。   As described above, not only the module casings 20a and 20b are directly bonded to each other, but also by the cover 70, the two are bonded more reliably.

なお、カバー７０を用いない場合は、上部クーリングダクト６０をカバー７０の代わりに用いる。   If the cover 70 is not used, the upper cooling duct 60 is used instead of the cover 70.

上部クーリングダクト６０の両側端部には複数の接合穴６０ｂが形成されたフランジ６０ａが設けられている。また、モジュール用筐体２０ａ、２０ｂにも接合穴６０ｂに対応する穴を設けておく（不図示）。上部クーリングダクト６０の接合穴６０ｂとモジュール用筐体２０ａ、２０ｂの穴との間を接合ロッド５０で接合することで、モジュール用筐体２０ａ、２０ｂの両者の結合をより確実なものとすることができる。   Flange 60a formed with a plurality of joint holes 60b is provided at both end portions of upper cooling duct 60. Also, holes corresponding to the joint holes 60b are provided in the module housings 20a and 20b (not shown). By joining the joint hole 60b of the upper cooling duct 60 and the holes of the module housings 20a and 20b with the joint rod 50, the coupling of both of the module housings 20a and 20b is made more reliable. Can do.
