Description

本発明は、単電池セルが複数列置されてなる電池モジュールを複数有する組電池に関し、特に隣り合う電池モジュールどうしの間に、冷却媒体を流通させる冷却通路を有するスペーサが介在する組電池装置に関するものである。   The present invention relates to an assembled battery having a plurality of battery modules in which a plurality of unit cells are arranged, and particularly to an assembled battery device in which a spacer having a cooling passage for circulating a cooling medium is interposed between adjacent battery modules. Is.

従来の組電池装置は、単電池セルどうしの間にスペーサを介在させ、隣接する単電池セルの最も広い側面どうしがスペーサを介して互いに対向するように交互に複数個列設し、両端に拘束板を配置して拘束ロッドなどによって列設方向に拘束することが行われている。また、単電池の劣化の原因となっている単電池セル間における温度差を抑えるため、冷却通路の入口側から出口側に向かうにつれて、冷却媒体とスペーサとの接触面積を大きくする形態とされている（特許文献１）。しかし、単電池セル間のスペーサの形状が複雑となり、且つ冷却通路の入口側・出口側に注意して各スペーサを単電池セルに組付けしなければならない。
特開２００６−０７３４６１号公報 In the conventional battery pack apparatus, a spacer is interposed between the unit cells, and a plurality of rows are alternately arranged so that the widest side surfaces of adjacent unit cells face each other with the spacer interposed therebetween, and restrained at both ends. A plate is arranged and restrained in a row direction by a restraining rod or the like. In addition, in order to suppress the temperature difference between the single battery cells causing the deterioration of the single battery, the contact area between the cooling medium and the spacer is increased from the inlet side to the outlet side of the cooling passage. (Patent Document 1). However, the shape of the spacers between the unit cells becomes complicated, and each spacer must be assembled to the unit cells while paying attention to the inlet side and the outlet side of the cooling passage.
JP 2006-077341 A

解決しようとする問題点は、各単電池セル間のスペーサの形状が複雑となり、且つ冷却通路の入口・出口を注意して各スペーサを単電池セルに組付けしなければならない点である。   The problem to be solved is that the shape of the spacers between the single battery cells is complicated, and the spacers must be assembled to the single battery cells while paying attention to the inlet / outlet of the cooling passage.

本発明は、直方体形状をなす単電池セルと、電気絶縁性のスペーサと、板状の熱伝導部材とが、この順序で互いに密着して列設されてなり、上記列設方向の両端から加圧拘束されてなる組電池装置であって、上記単電池セルと上記スペーサとの間には、冷却媒体が流れる冷却通路が形成され、上記熱伝導部材は、上記電池セルの最も広い側面に密着する密着表面とを備え、上記熱伝導部材は、弾性材料で構成されて加圧拘束されることにより、並列配置された複数の上記単電池セルを橋渡しして、密着していることを特徴とする。 好適な手段として、上記スペーサは上記単電池セル方向に突出したリブを備え、上記冷却通路は上記スペーサと上記単電池セルとの間に形成された空間である構成をとることができる。
In the present invention, a unit cell having a rectangular parallelepiped shape, an electrically insulating spacer, and a plate-like heat conducting member are arranged in close contact with each other in this order, and are added from both ends in the arrangement direction. A battery pack device that is pressure-constrained, wherein a cooling passage through which a cooling medium flows is formed between the single battery cell and the spacer, and the heat conducting member is in close contact with the widest side surface of the battery cell. The heat conducting member is made of an elastic material and is pressure-constrained, thereby bridging the plurality of unit cells arranged in parallel to be in close contact with each other. To do. As a preferable means, the spacer may include a rib protruding in the direction of the unit cell, and the cooling passage may be a space formed between the spacer and the unit cell.

本発明の組電池装置は、熱伝導部材で各単電池セル間の熱移動を行える為、単電池セル毎の温度差が発生しにくくなり、単電池セルの劣化を抑え且つ単電池セルへのスペーサの組付けが容易にできる。
また、冷却通路に寄与するリブは、スペーサと樹脂で一体に射出成形した為、附形及び成形が容易にできる。 Since the assembled battery device of the present invention can perform heat transfer between each single battery cell with the heat conducting member, a temperature difference between the single battery cells is less likely to occur, suppressing deterioration of the single battery cell and The spacer can be easily assembled.
Further, since the rib contributing to the cooling passage is integrally injection-molded with the spacer and the resin, it can be easily shaped and molded.

単電池セルの劣化を抑え且つ方向を問わずスペーサを単電池セルに組付けする目的を、簡易な構成で実現した。   The purpose of suppressing the deterioration of the unit cell and assembling the spacer to the unit cell regardless of the direction is realized with a simple configuration.

図１に、本実施例に係る組電池装置の分解斜視図を示す。この組電池装置では、直方体形状をなす単電池セル１と、板状に形成された熱伝導部材３と、電気絶縁性樹脂製のスペーサ２とからなる。単電池セル１は並列に２個配置されている。また、単電池セル１、スペーサ２、熱伝導部材３とが、この順序で互いに密着して複数個列設されている。そして両端には樹脂製の拘束プレート４が配置され、図示しない拘束ロッドによって単電池セル１とスペーサ２とが互いに密着するように加圧された状態で拘束されている。その状態で、図２に示すように全体が電気絶縁性樹脂製のケーシング５に収納されている。   FIG. 1 is an exploded perspective view of the assembled battery device according to the present embodiment. This assembled battery device includes a single battery cell 1 having a rectangular parallelepiped shape, a heat conductive member 3 formed in a plate shape, and a spacer 2 made of an electrically insulating resin. Two unit cells 1 are arranged in parallel. A plurality of unit cells 1, spacers 2, and heat conducting members 3 are arranged in close contact with each other in this order. Resin constraining plates 4 are disposed at both ends, and are constrained in a state in which the unit cells 1 and the spacers 2 are pressed against each other by a constraining rod (not shown). In this state, as shown in FIG. 2, the whole is housed in a casing 5 made of an electrically insulating resin.

単電池セル１はリチウムイオン二次電池であり、極板、セパレータ、電解液などの電池要素がアルミニウム製の筐体１０に収納されている。筐体１０の上部には、正極及び負極の一対の電極１１が突出している。また筐体１０は６個の側面をもち、最も広い側面１２どうしが互いに対向するように列設されている。   The unit cell 1 is a lithium ion secondary battery, and battery elements such as an electrode plate, a separator, and an electrolytic solution are housed in an aluminum casing 10. A pair of positive and negative electrodes 11 protrude from the upper portion of the housing 10. The housing 10 has six side surfaces, and the widest side surfaces 12 are arranged in a row so as to face each other.

スペーサ２はＰＰ（ポリプロピレン樹脂）から形成され、図２に示すように、上板２０と下板２１とが縦板２２で連結された断面略エ字形状に形成されている。縦板２２の一方の側面には、リブ２３が側面長手方向へ形成され、上板２０には単電池セル１の電極１１との干渉を避けるための切り欠き２５が形成されている。   The spacer 2 is made of PP (polypropylene resin), and has a substantially E-shaped cross section in which an upper plate 20 and a lower plate 21 are connected by a vertical plate 22 as shown in FIG. A rib 23 is formed on one side surface of the vertical plate 22 in the longitudinal direction of the side surface, and a cutout 25 for avoiding interference with the electrode 11 of the unit cell 1 is formed on the upper plate 20.

熱伝導部材３は、アスカーＣ硬度が４５、熱伝導率が５Ｗ／ｍ・Ｋのシリコーンゴムから形成されている。この熱伝導部材３は板状をなし、最も広い表面が密着表面３１を構成している。   The heat conductive member 3 is made of silicone rubber having an Asker C hardness of 45 and a heat conductivity of 5 W / m · K. The heat conducting member 3 has a plate shape, and the widest surface forms the contact surface 31.

そして、図２に示すように拘束状態において、単電池セル１は一方の側面１２Ａがスペーサ２のリブ２３に隣接し、他方の側面１２Ｂが熱伝導部材３の密着表面３１に密着した状態になっている。このようにスペーサ２にリブ２３が形成されている為、単電池セル１とスペーサ２との間に高さ１〜２ｍｍの冷却通路２４が形成される。この冷却通路２４は、エアコンの風などの冷却媒体が流通する通路として利用される。また、熱伝導部材３は並列配置された複数の単電池セル１を橋渡しするように密着している。   As shown in FIG. 2, in the constrained state, the single battery cell 1 is in a state where one side surface 12 </ b> A is adjacent to the rib 23 of the spacer 2 and the other side surface 12 </ b> B is in close contact with the contact surface 31 of the heat conducting member 3. ing. Since the ribs 23 are thus formed in the spacer 2, a cooling passage 24 having a height of 1 to 2 mm is formed between the single battery cell 1 and the spacer 2. The cooling passage 24 is used as a passage through which a cooling medium such as air from an air conditioner flows. Further, the heat conducting member 3 is in close contact so as to bridge the plurality of single cells 1 arranged in parallel.

ケーシング５とスペーサ２との間には隙間５１が形成され、電極１１との干渉が回避されている。この隙間５１にはエアコンの風（冷却媒体）が流通するように構成されている。   A gap 51 is formed between the casing 5 and the spacer 2 to avoid interference with the electrode 11. The air gap (cooling medium) of the air conditioner flows through the gap 51.

このような本実施例の組電池装置によれば、ケーシング内に導入された冷却媒体が、隙間５１及び冷却通路２４を矢印Ｗ方向へ流通することで、単電池セル１を冷却することができる（図１）。この時、入口側単電池セル１Ａは、出口側単電池セル１Ｂに比べ、冷却されやすいが、熱伝導部材３によって複数の単電池セル１は橋渡しされている為、冷却されにくい出口側単電池セル１Ｂの熱が熱伝導部材３を介して入口側単電池セル１Ａに熱移動し（矢印Ｃ方向へ熱移動し）、各単電池セル間の温度差を小さくすることできる。従って、電池の劣化を抑えることができる。また各単電池セル１の温度差は冷却通路２４の形状に依存しない為、スペーサ２は、冷却通路２４の入口側・出口側の形状を異なる形状にしなくても良く簡易な形状で成形でき、また方向を問わずスペーサ２を単電池セル１に組付けすることも可能である。さらに、スペーサ２から単電池セル１方向へ突出したリブ２３は、樹脂で一体に射出成形したので、附形及び成形が簡単にできる。   According to such an assembled battery device of the present embodiment, the cooling medium introduced into the casing flows through the gap 51 and the cooling passage 24 in the arrow W direction, so that the single battery cell 1 can be cooled. (FIG. 1). At this time, the inlet side single battery cell 1A is more easily cooled than the outlet side single battery cell 1B. However, since the plurality of single battery cells 1 are bridged by the heat conducting member 3, the outlet side single battery is difficult to be cooled. The heat of the cell 1B is transferred to the inlet side single battery cell 1A via the heat conducting member 3 (heat transferred in the direction of arrow C), and the temperature difference between the single battery cells can be reduced. Therefore, deterioration of the battery can be suppressed. In addition, since the temperature difference of each battery cell 1 does not depend on the shape of the cooling passage 24, the spacer 2 can be formed in a simple shape without having to make the shapes of the inlet side and the outlet side of the cooling passage 24 different, It is also possible to assemble the spacer 2 to the single battery cell 1 regardless of the direction. Furthermore, since the rib 23 protruding from the spacer 2 toward the single battery cell 1 is integrally injection-molded with resin, it can be easily shaped and molded.

熱伝導部材３は、弾性材料（シリコーンゴム）で構成されている為、加圧拘束する場合、ゴムが弾性圧縮されるので、単電池セル１の筐体１０やスペーサ２の寸法バラツキを吸収できる。また、単電池セル１が熱膨張しても吸収することもできる。さらに、熱伝導部材３の密着表面３１が単電池セル１の表面に追従して弾性変形するので、確実な密着が得られる。   Since the heat conducting member 3 is made of an elastic material (silicone rubber), when the pressure is restricted, the rubber is elastically compressed, so that the dimensional variation of the casing 10 and the spacer 2 of the unit cell 1 can be absorbed. . Moreover, even if the unit cell 1 is thermally expanded, it can be absorbed. Furthermore, since the close contact surface 31 of the heat conducting member 3 elastically deforms following the surface of the single battery cell 1, reliable contact is obtained.

なお、この発明は上記実施例に限られるものではなく、その要旨を逸脱しない種々の態様において実施することが可能である。例えば、本実施例では冷却通路２４を形成する為に、スペーサ２にリブ２３を形成しているが、スペーサ２にリブを設けず、単電池セル１の筐体１０からリブを突設させ、冷却通路２４を形成しても良い。   In addition, this invention is not restricted to the said Example, It is possible to implement in the various aspect which does not deviate from the summary. For example, in this embodiment, the ribs 23 are formed on the spacer 2 in order to form the cooling passage 24. However, the ribs are not provided on the spacer 2, and the ribs are protruded from the casing 10 of the unit cell 1, A cooling passage 24 may be formed.

また、熱伝導部材３は、熱伝導性と電気絶縁性とを有するシリコーンゴムからなるマトリックスと、マトリックス中に含まれ、繊維の長さ方向の熱伝導率が約６０Ｗ／ｍＫの超高分子量ポリエチレン繊維からなる繊維部材とから板状に形成されているものを用いても良い。繊維部材としては他に、窒化ホウ素等が好適に用いることができる。繊維部材の長さ方向を矢印Ｃ方向と一致するように熱伝導部材３を成形すれば、矢印Ｃ方向への熱移動が速やかに行われる為、各単電池セル間の温度差を発生させにくく、より電池の劣化を抑えることができる。   The heat conducting member 3 includes a matrix made of silicone rubber having thermal conductivity and electrical insulation, and an ultrahigh molecular weight polyethylene that is contained in the matrix and has a thermal conductivity of about 60 W / mK in the fiber length direction. You may use what is formed in plate shape from the fiber member which consists of fibers. In addition, boron nitride or the like can be suitably used as the fiber member. If the heat conducting member 3 is formed so that the length direction of the fiber member coincides with the direction of the arrow C, heat transfer in the direction of the arrow C is performed quickly, so that it is difficult to generate a temperature difference between the battery cells. Thus, deterioration of the battery can be further suppressed.
