Description

本発明は、底板と上板との間に複数の蓄電池を収納する蓄電池収納箱に関する。   The present invention relates to a storage battery storage box that stores a plurality of storage batteries between a bottom plate and an upper plate.

近年、地球環境問題への関心が高まりクリーンエネルギーの導入が進められ、より高エネルギー密度、高エネルギー容量の電力貯蔵用蓄電池やスマートグリッド用蓄電池の開発が求められている。これらの用途で使用される蓄電池は、複数の単電池を直列又は並列接続することが行われ、組電池として使用される。
この種の組電池には、底板と上板との間に複数の蓄電池を横並びに収納する蓄電池収納箱を多段で備えるものがあり、蓄電池の電槽にリブを設け、リブの間を通風口にして放熱を促す構成が提案されている（例えば、特許文献１参照）。 In recent years, interest in global environmental issues has increased and the introduction of clean energy has been promoted, and the development of storage batteries for power storage and smart grids with higher energy density and higher energy capacity has been demanded. A storage battery used in these applications is used as an assembled battery by connecting a plurality of single cells in series or in parallel.
In this type of battery pack, there is a battery pack storage box that stores a plurality of storage batteries side by side between a bottom plate and an upper plate, and a rib is provided in the battery case of the storage battery. Thus, a configuration that promotes heat dissipation has been proposed (see, for example, Patent Document 1).

特開２０１０−２７７８４７号公報JP 2010-277847 A

しかし、電槽にリブを設ける構造は、通風口の大きさが小さく、放熱が十分でない場合や放熱量に偏りが生じるおそれがあり、また、電槽の構造をリブ付きに変更しなければならない、という制約がある。また、従来の構成は、蓄電池毎の放熱ムラが生じ、蓄電池毎の温度に偏りが生じ易く、組電池全体の平均温度を下げられたとしても各蓄電池の状態に差が生じるため、特定の蓄電池の劣化が進みやすくなり、組電池としては短寿命になっていた。
本発明は、上述した事情を鑑みてなされたものであり、放熱性の向上と各蓄電池の均熱化とを可能にした蓄電池収納箱を提供することにある。 However, the structure in which the rib is provided in the battery case has a small size of the ventilation opening, and there is a possibility that the heat dissipation is not sufficient or the heat dissipation amount may be biased, and the structure of the battery case must be changed to a rib type. There is a restriction that. In addition, the conventional configuration causes uneven heat dissipation for each storage battery, and the temperature for each storage battery tends to be biased. Even if the average temperature of the entire assembled battery is lowered, a difference occurs in the state of each storage battery. Deterioration of the battery becomes easy to progress, and the battery life is short.
The present invention has been made in view of the above-described circumstances, and it is an object of the present invention to provide a storage battery storage box capable of improving heat dissipation and equalizing each storage battery.

上述した課題を解決するため、本発明は、底板と上板との間に複数の蓄電池を収納する蓄電池収納箱において、前記蓄電池の収納空間を左右に仕切る複数の中仕切り板を備え、前記底板と前記上板と前記中仕切り板の少なくともいずれかに、予め定めた前記蓄電池間に通気路を形成する開口部を設け、残りの前記蓄電池間への通気は遮断することを特徴とする。この構成によれば、放熱性を向上させるとともに、予め定めた蓄電池が他の蓄電池よりも温度が高い場合にその温度の偏りを抑えることができる。これにより、放熱性の向上と各蓄電池の均熱化が可能になる。   In order to solve the above-described problems, the present invention provides a storage battery storage box for storing a plurality of storage batteries between a bottom plate and an upper plate, and includes a plurality of partition plates for partitioning the storage space of the storage batteries in the left and right directions, In addition, at least one of the upper plate and the partition plate is provided with an opening for forming a ventilation path between the predetermined storage batteries, and ventilation between the remaining storage batteries is blocked. According to this structure, while improving heat dissipation, when the temperature of the predetermined storage battery is higher than another storage battery, the bias | inclination of the temperature can be suppressed. Thereby, the improvement of heat dissipation and the equalization | homogenization of each storage battery are attained.

また、本発明は、前記予め定めた前記蓄電池間に配置される前記中仕切り板は、上下に開放する空洞部を有し、前記底板及び前記上板の少なくともいずれかは、前記空洞部に連通するスリットを有することを特徴とする。この構成によれば、空洞部及びスリットにより、上下方向の通気を促し、効率よく放熱することができる。   Further, according to the present invention, the partition plate disposed between the predetermined storage batteries has a hollow portion that opens up and down, and at least one of the bottom plate and the upper plate communicates with the hollow portion. It has the slit to do. According to this configuration, the hollow portion and the slit can facilitate the ventilation in the vertical direction and efficiently radiate heat.

また、本発明は、前記予め定めた前記蓄電池間に配置される前記中仕切り板は、前後に開放する空洞部を有することを特徴とする。この構成によれば、前後方向の通気によっても放熱することができる。
また、本発明は、前記蓄電池を前方から押さえるとともに前記中仕切り板の前面を覆う押さえ板を有し、前記押さえ板は前記中仕切り板の前記空洞部と連通するスリットを有することを特徴とする。この構成によれば、簡易に前後方向への通気を行うことができる。 Further, the present invention is characterized in that the partition plate arranged between the predetermined storage batteries has a hollow portion that opens front and rear. According to this configuration, heat can be radiated also by ventilation in the front-rear direction.
Further, the present invention has a pressing plate that presses the storage battery from the front and covers the front surface of the partition plate, and the pressing plate has a slit that communicates with the hollow portion of the partition plate. . According to this configuration, ventilation in the front-rear direction can be performed easily.

また、本発明は、前記底板と前記上板と前記中仕切り板の少なくともいずれかにより、前記残りの前記蓄電池間への通気を遮断することを特徴とする。この構成によれば、蓄電池収納箱が有する構成を用いて、通気を遮断することができ、部品点数の増大を回避することもできる。
また、本発明は、左右両端に位置する前記蓄電池とその隣の前記蓄電池との間の通気が遮断されることを特徴とする。この構成によれば、側方の外部空間に放熱し易い蓄電池の著しい温度低下を抑制することができ、他の蓄電池との均熱化を図り易くなる。
また、本発明は、最も下に位置する前記蓄電池間の通気が遮断されることを特徴とする。この構成によれば、下方の外部空間に放熱し易い蓄電池の著しい温度低下を抑制することができ、他の蓄電池との均熱化を図り易くなる。 Further, the present invention is characterized in that ventilation between the remaining storage batteries is blocked by at least one of the bottom plate, the upper plate, and the partition plate. According to this configuration, it is possible to block ventilation by using the configuration of the storage battery storage box, and it is possible to avoid an increase in the number of components.
Further, the present invention is characterized in that ventilation between the storage battery located at both left and right ends and the adjacent storage battery is blocked.

以下、図面を参照して本発明の一実施の形態について説明する。
図１は、実施形態に係る蓄電池収納箱を備える組電池（蓄電池システム）を示す図である。
組電池１０は、非常用電源や自家発電装置の起動等、災害時のバックアップに用いられる産業用の組電池であり、複数の蓄電池（単電池に相当）１１を横並びで収納する複数の蓄電池収納箱２２を備えている。これら蓄電池収納箱２２は、多段に積み上げられ、上下段に隣接する前記蓄電池収納箱２２の下段の上部のフレーム２６と上段の下部のフレーム２７との４隅が、ボルト及びナットからなる連結部材（不図示）で各々連結されている。
本実施形態では、蓄電池収納箱２２を４段とし、各蓄電池収納箱２２に６個の蓄電池１１を収納し、これによって２４個の蓄電池１１を収納する組電池１０を構成している。但し、この構成に限らず、蓄電池収納箱２２の段数や収納数は適宜に変更可能である。また、各蓄電池収納箱２２は同じ構成である。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Drawing 1 is a figure showing an assembled battery (storage battery system) provided with a storage battery storage box concerning an embodiment.
The assembled battery 10 is an industrial assembled battery used for backup in the event of a disaster such as an emergency power supply or a private power generator, and stores a plurality of storage batteries (corresponding to single cells) 11 side by side. A box 22 is provided. These storage battery storage boxes 22 are stacked in multiple stages, and four corners of the lower upper frame 26 and the upper lower frame 27 adjacent to the upper and lower storage battery boxes 22 are connecting members (bolts and nuts). (Not shown).
In the present embodiment, the storage battery storage boxes 22 are arranged in four stages, and six storage batteries 11 are stored in each storage battery storage box 22, thereby configuring the assembled battery 10 storing 24 storage batteries 11. However, it is not limited to this configuration, and the number of stages and the number of stored storage battery storage boxes 22 can be changed as appropriate. Moreover, each storage battery storage box 22 is the same structure.

図２は、蓄電池収納箱２２を正面から見た図であり、図３は上方から見た図である。
蓄電池収納箱２２は、底板２３と、底板２３の上方に間隔を空けて配置される上板２４と、底板２３と上板２４の左右端部間をつなぐ左右一対の側板２５と、後板３０とを備え、前面が開口する前面開口収納部２２Ａ（図２）を有する箱形状に形成されている。この蓄電池収納箱２２を構成する各板２３〜２５は、鉄やステンレス鋼等の金属板で製作されている。
蓄電池１１は、非常用電源等に用いられる制御弁式蓄電池であり、電極や電解液を収容する直方体形状の電槽１２と、この電槽１２の前部を構成する電槽蓋１３とを備えている。電槽１２はリブを備えない構造に形成されている。また、電槽蓋１３には、正極端子１５Ａ、負極端子１５Ｂ及び制御弁１５Ｃが取り付けられている。なお、以下の説明において、正極端子１５Ａ、負極端子１５Ｂを特に区別する必要が無い場合は端子１５と表記する。 2 is a view of the storage battery storage box 22 as seen from the front, and FIG. 3 is a view as seen from above.
The storage battery storage box 22 includes a bottom plate 23, a top plate 24 disposed above the bottom plate 23 with a space therebetween, a pair of left and right side plates 25 connecting the left and right ends of the bottom plate 23 and the top plate 24, and a rear plate 30. And is formed in a box shape having a front opening storage portion 22A (FIG. 2) whose front surface is open. Each plate 23-25 which comprises this storage battery storage box 22 is manufactured with metal plates, such as iron and stainless steel.
The storage battery 11 is a control valve storage battery used for an emergency power source or the like, and includes a rectangular parallelepiped battery case 12 that accommodates electrodes and an electrolyte solution, and a battery case lid 13 that constitutes a front portion of the battery case 12. ing. The battery case 12 is formed in a structure without ribs. The battery case lid 13 is provided with a positive terminal 15A, a negative terminal 15B, and a control valve 15C. In the following description, the positive electrode terminal 15A and the negative electrode terminal 15B are denoted as the terminal 15 when it is not necessary to distinguish between them.

この蓄電池１１は、蓄電池収納箱２２に装填されて、端子１５等が取り付けられた電槽蓋１３を、蓄電池収納箱２２の前方に向け、且つ、蓄電池収納箱２２よりも前方に出た状態とされる。このようにして蓄電池１１を装填した後、蓄電池収納箱２２の前部に押さえ板（止め金具とも称する）３１が固定される。
図２に示すように、各押さえ板３１は、上下一対の締結部材３２によって蓄電池収納箱２２の底板２３と上板２４とに固定され、各蓄電池１１を前方から押さえ、通常の使用時において蓄電池収納箱２２から蓄電池１１が抜け落ちないようにしている。この押さえ板３１により、地震や転倒により蓄電池１１が抜け落ちるのを防止することが可能になる。このようにして単一の蓄電池収納箱２２に複数の蓄電池１１を装填し、押さえ板３１で固定したものを「ユニット型蓄電池」という。 The storage battery 11 is loaded in the storage battery storage box 22, and the battery case lid 13 to which the terminals 15 and the like are attached faces the front of the storage battery storage box 22 and protrudes forward from the storage battery storage box 22. Is done. After loading the storage battery 11 in this way, a holding plate (also referred to as a stopper) 31 is fixed to the front portion of the storage battery storage box 22.
As shown in FIG. 2, each holding plate 31 is fixed to the bottom plate 23 and the upper plate 24 of the storage battery storage box 22 by a pair of upper and lower fastening members 32, holds each storage battery 11 from the front, and the storage battery in normal use. The storage battery 11 is prevented from falling off from the storage box 22. The holding plate 31 can prevent the storage battery 11 from falling off due to an earthquake or a fall. A battery in which a plurality of storage batteries 11 are loaded in a single storage battery storage box 22 and fixed by a pressing plate 31 is referred to as a “unit storage battery”.

組電池１０の使用時には、各蓄電池１１の端子１５同士が、導体である接続板３３（図１参照）によって電気的に接続した状態とされる。接続板３３は、隣接する蓄電池１１の端子１５同士を接続することによって、必要個数の蓄電池１１を直列或いは並列に接続し、必要電圧や必要容量を確保した「組電池」に構成している。
なお、図１では、接続板３３を銅板で形成し、蓄電池１１を直列に接続した場合を示している。接続板３３は、銅板に限らず、他の金属板や配線といった他の導体を用いることも可能である。 When the assembled battery 10 is used, the terminals 15 of the storage batteries 11 are electrically connected by a connection plate 33 (see FIG. 1) that is a conductor. The connection plate 33 is configured as an “assembled battery” in which a necessary number of storage batteries 11 are connected in series or in parallel by connecting terminals 15 of adjacent storage batteries 11 to ensure necessary voltage and necessary capacity.
In addition, in FIG. 1, the connection board 33 is formed with a copper plate, and the case where the storage battery 11 is connected in series is shown. The connection plate 33 is not limited to a copper plate, and other conductors such as other metal plates and wirings can also be used.

図１〜図３に示すように、蓄電池収納箱２２には、蓄電池１１の収納空間を左右に仕切る仕切り板である複数の中仕切り板４１が設けられている。図１〜図３に示す例では、蓄電池１１と中仕切り板４１とが交互に配置され、蓄電池１１が６個の場合は、中仕切り板４１が５個設けられている。
図１〜図３に示すように、中仕切り板４１は、内部に空洞部Ｓを有し、この空洞部Ｓが底板２３及び上板２４に設けたスリット５１、５２（５２については後述する図参照）と連通することによって、左右の蓄電池１１間に通気路５５を形成する。この通気路５５により左右の蓄電池１１からの熱を効率よく外部に放出することができる。 As shown in FIGS. 1 to 3, the storage battery storage box 22 is provided with a plurality of partition plates 41, which are partition plates that partition the storage space of the storage battery 11 to the left and right. In the example shown in FIGS. 1-3, the storage battery 11 and the partition plate 41 are arrange | positioned alternately, and when the storage battery 11 is six, the five partition plates 41 are provided.
As shown in FIGS. 1 to 3, the partition plate 41 has a hollow portion S therein, and slits 51 and 52 (52 are described later in detail) provided in the bottom plate 23 and the upper plate 24. The air passage 55 is formed between the left and right storage batteries 11. The air passage 55 can efficiently release heat from the left and right storage batteries 11 to the outside.

図４は、中仕切り板４１の斜視図を示している。中仕切り板４１は、左右一対の側板４２と、これら側板４２同士を所定距離だけ左右に離して連結する複数の連結体４３とを有する。
左右の側板４２は、同形状であり、左右の蓄電池１１の側面（蓄電池１１同士が対向する面に相当）と同形状の矩形板形状に形成される。
連結体４３は、左右の側板４２を、その間に空洞部Ｓを空けて連結するとともに、空洞部Ｓを上下及び前後に開放させる。より具体的には、連結体４３は、左右の側板４２の対向する４隅同士を独立して連結する梁となるように左右方向に延びる細板形状に形成され、左右の側板４２間の上下に開口部ＫＡ、ＫＢを形成するとともに、前後に開口部ＫＣ、ＫＤを形成する。 FIG. 4 shows a perspective view of the partition plate 41. The middle partition plate 41 includes a pair of left and right side plates 42 and a plurality of connecting bodies 43 that connect the side plates 42 to each other at a predetermined distance.
The left and right side plates 42 have the same shape, and are formed in a rectangular plate shape that is the same shape as the side surfaces of the left and right storage batteries 11 (corresponding to the surfaces where the storage batteries 11 face each other).
The connecting body 43 connects the left and right side plates 42 with a cavity S therebetween, and opens the cavity S up and down and front and rear. More specifically, the connecting body 43 is formed in a thin plate shape that extends in the left-right direction so as to be a beam that independently connects the four opposing corners of the left and right side plates 42, and the upper and lower sides between the left and right side plates 42. The openings KA and KB are formed at the front and the openings KC and KD are formed in the front and rear.

上記の中仕切り板４１は、熱伝導性が高い材料で形成すれば良く、蓄電池収納箱２２と同じ金属板でも良いし、銅、アルミニウム合金、マグネシウム合金等の様々な金属材や樹脂等を用いることが可能である。また、中仕切り板４１を、押出成形法やダイキャスト成形法、ブロー成形法等を用いて成形しても良い。
中仕切り板４１を蓄電池収納箱２２に配置した場合には、図３に示すように、中仕切り板４１の上下の開口部ＫＡ、ＫＢが、底板２３及び上板２４に設けたスリット５１、５２に連通する。これにより、上下に空気が流通自在な通気路５５が形成され、左右の蓄電池１１からの熱を上方に放出することができる。 The partition plate 41 may be formed of a material having high thermal conductivity, may be the same metal plate as the storage battery storage box 22, and uses various metal materials such as copper, aluminum alloy, magnesium alloy, resin, and the like. It is possible. Moreover, you may shape | mold the partition plate 41 using the extrusion molding method, the die-cast molding method, the blow molding method, etc.
When the middle partition plate 41 is disposed in the storage battery storage box 22, the upper and lower openings KA and KB of the middle partition plate 41 are slits 51 and 52 provided in the bottom plate 23 and the upper plate 24 as shown in FIG. 3. Communicate with. Thereby, the ventilation path 55 which can distribute | circulate air up and down is formed, and the heat | fever from the storage battery 11 on either side can be discharge | released upwards.

また、図２に示すように、中仕切り板４１の前方の開口部ＫＣは、押さえ板３１に設けられたスリット３１Ａに連通する。これによって、左右の蓄電池１１からの熱を前方にも放出することができる。ここで、蓄電池１１は、端子１５等が取り付けられた電槽蓋１３側に電流密度が高くなりやすいので、前側の方が後側よりも温度が高くなり易い。本構成では、中仕切り板４１が前方に熱を放出可能に形成されるので、蓄電池１１の前側と後側の温度差を低減することができ、蓄電池１１自体の温度の均等化（均熱化）を図ることができる。
なお、蓄電池収納箱２２は、前面が開口し後面が閉じた形状であるため、中仕切り板４１を蓄電池収納箱２２に装填した場合には、蓄電池１１の後側の熱が放熱しにくく、これによっても蓄電池１１の冷却及び前後温度の均熱化に有利である。但し、より放熱を促したい場合等には、中仕切り板４１を装填する部分の蓄電池収納箱２２の後面を開口させる、といった各種の変更を行ってもよい。 Further, as shown in FIG. 2, the opening KC in front of the partition plate 41 communicates with a slit 31 </ b> A provided in the pressing plate 31. Thereby, the heat from the left and right storage batteries 11 can be released forward. Here, since the storage battery 11 tends to have a high current density on the battery case lid 13 side to which the terminals 15 and the like are attached, the temperature on the front side tends to be higher than that on the rear side. In this configuration, since the partition plate 41 is formed so as to be able to release heat forward, the temperature difference between the front side and the rear side of the storage battery 11 can be reduced, and the temperature of the storage battery 11 itself can be equalized (temperature equalization). ).
In addition, since the storage battery storage box 22 has a shape in which the front surface is opened and the rear surface is closed, when the partition plate 41 is loaded in the storage battery storage box 22, the heat on the rear side of the storage battery 11 is difficult to dissipate. This is advantageous for cooling the storage battery 11 and soaking the front and rear temperatures. However, when it is desired to further radiate heat, various changes such as opening the rear surface of the storage battery storage box 22 where the partition plate 41 is loaded may be performed.

この中仕切り板４１の前後長（＝側板の前後長）ＬＡ（図４参照）は、蓄電池収納箱２２の奥行き（前後長）Ｌ１（図３参照）と略同じ長さに形成されており、中仕切り板４１の高さＨＡ（＝側板４２の高さ）は、蓄電池収納箱２２の底板２３と上板２４との離間距離Ｈ１（図２参照）と略同じ長さに形成されている。これによって、中仕切り板４１は蓄電池収納箱２２の底板２３と上板２４との間に挟まれた状態で立設し、蓄電池収納箱２２の内部空間（前面開口収納部２２Ａ）を左右に仕切る。また、中仕切り板４１は、蓄電池収納箱２２の前面開口収納部２２Ａから前後に出し入れ自在であり、且つ、底板２３や上板２４に沿って左右にスライド自在である。
従って、中仕切り板４１の位置を、蓄電池１１の左右位置に合わせて容易に調整することができ、図１〜図３に示すように、蓄電池１１との間に隙間が空かないように中仕切り板４１を容易に配置することができる。この配置により、中仕切り板４１の左右の側板４２が、左右（両隣り）の蓄電池１１の側面に密着し、蓄電池１１の熱が側板４２を介して空洞部Ｓ内に放出される。 The front-rear length (= front-rear length of the side plate) LA (see FIG. 4) of the partition plate 41 is formed to be substantially the same as the depth (front-rear length) L1 (see FIG. 3) of the storage battery storage box 22. The height HA (= the height of the side plate 42) of the middle partition plate 41 is formed to be substantially the same as the distance H1 (see FIG. 2) between the bottom plate 23 and the upper plate 24 of the storage battery storage box 22. Thus, the intermediate partition plate 41 is erected in a state of being sandwiched between the bottom plate 23 and the upper plate 24 of the storage battery storage box 22, and partitions the internal space (front opening storage portion 22A) of the storage battery storage box 22 to the left and right. . Further, the partition plate 41 can be inserted into and removed from the front opening storage portion 22 </ b> A of the storage battery storage box 22, and can be slid left and right along the bottom plate 23 and the upper plate 24.
Therefore, the position of the partition plate 41 can be easily adjusted according to the left and right positions of the storage battery 11, and the partition is arranged so that there is no gap between the storage battery 11 as shown in FIGS. 1 to 3. The plate 41 can be easily arranged. With this arrangement, the left and right side plates 42 of the partition plate 41 are in close contact with the side surfaces of the left and right (both adjacent) storage batteries 11, and the heat of the storage battery 11 is released into the cavity S via the side plates 42.

また、底板２３に設けられるスリット５１は、図３に示すように、前後方向に長い長方形の孔形状であって、その幅（左右長）ＷＳが、中仕切り板４１の上下の空洞部Ｓの幅ＷＡ以下であり、かつ、その前後長ＬＳが、中仕切り板４１の前後長ＬＡ以下である形状に形成されている。このため、中仕切り板４１の位置が左右や前後に多少ずれたとしても、各スリット５１を、各中仕切り板４１の上下に開放する空洞部Ｓに連通させることができる。なお、上板２４に設けられるスリット５２についても、上記スリット５１と同様である。   Further, as shown in FIG. 3, the slit 51 provided in the bottom plate 23 has a rectangular hole shape that is long in the front-rear direction, and has a width (horizontal length) WS of the upper and lower cavities S of the partition plate 41. The width WA is equal to or smaller than that, and the front-rear length LS is formed in a shape equal to or smaller than the front-rear length LA of the partition plate 41. For this reason, even if the position of the partition plate 41 is slightly shifted from side to side or front and back, each slit 51 can be communicated with the cavity S that opens up and down of each partition plate 41. The slit 52 provided on the upper plate 24 is the same as the slit 51 described above.

また、蓄電池収納箱２２を多段に重ねた場合には、図１に示すように、上下の蓄電池収納箱２２間に左右に連続して外気に連通する空間部が形成される。このため、空洞部Ｓ内の通気によって、上下の蓄電池収納箱２２間からも外気が吸い上げられる。これによって、上下の蓄電池収納箱２２間の熱は、空洞部Ｓを経由して効率良く排出することが可能になり、蓄電池１１の放熱効果を向上させることができる。
さらに、本実施形態では、放熱性の向上に加え、蓄電池１１毎の温度の偏り（放熱ムラ）を低減するために、所定の蓄電池１１間だけに上記通気路５５を形成して放熱を促し、残りの蓄電池１１間には上下及び／又は前後への通気路５５を形成しないようにして放熱ムラを抑制するようにしている。以下、具体的な実施例を説明する。なお、実施例は以下のものに限定されるものではない。 Further, when the storage battery storage boxes 22 are stacked in multiple stages, as shown in FIG. 1, a space portion is formed between the upper and lower storage battery storage boxes 22 so as to be continuously communicated with the left and right. For this reason, the outside air is sucked up between the upper and lower storage battery storage boxes 22 by the ventilation in the cavity S. Thereby, the heat between the upper and lower storage battery storage boxes 22 can be efficiently discharged via the cavity S, and the heat dissipation effect of the storage battery 11 can be improved.
Furthermore, in this embodiment, in addition to improving heat dissipation, in order to reduce temperature deviation (heat dissipation unevenness) for each storage battery 11, the air passage 55 is formed only between the predetermined storage batteries 11 to promote heat dissipation, The upper and lower and / or front and rear air passages 55 are not formed between the remaining storage batteries 11 so as to suppress uneven heat dissipation. Hereinafter, specific examples will be described. In addition, an Example is not limited to the following.

Furthermore, in 1st Example, between the storage battery 11 (it shows by 11c in FIG. 5) located in the right-and-left both ends of the lowest step, and the storage battery 11 (it shows by 11d in FIG. 5) adjacent to the storage battery 11c. The ventilation in the front-rear direction is restricted, and the ventilation in the vertical direction between the remaining storage batteries 11 (including the storage batteries 11a and 11b) is allowed.

図６は、最上段に相当する１段目から３段目の蓄電池収納箱２２を模式的に示した図であり、図６（Ａ）は上方から見た図、図６（Ｂ）は前方から見た図、図６（Ｃ）は下方から見た図である。なお、図６には、説明の便宜上、蓄電池１１、１１ａ、１１ｂの位置を符号だけで示している。
図６（Ａ）に示すように、蓄電池収納箱２２の上板２４には、蓄電池１１ａ、１１ｂを除く蓄電池１１間だけにスリット５１が形成され、蓄電池１１ａ、１１ｂ間は閉塞される。
また、図６（Ｃ）に示すように、蓄電池収納箱２２の底板２３についても、蓄電池１１ａ、１１ｂを除く蓄電池１１間だけにスリット５２が形成され、蓄電池１１ａ、１１ｂ間は閉塞される。 FIG. 6 is a diagram schematically showing the first to third storage battery storage boxes 22 corresponding to the uppermost stage. FIG. 6 (A) is a top view, and FIG. 6 (B) is a front view. FIG. 6C is a view seen from below. In addition, in FIG. 6, the position of the storage batteries 11, 11a, and 11b is shown only with the code | symbol for convenience of explanation.
As shown in FIG. 6A, the upper plate 24 of the storage battery storage box 22 is formed with a slit 51 only between the storage batteries 11 excluding the storage batteries 11a and 11b, and is closed between the storage batteries 11a and 11b.
As shown in FIG. 6C, the bottom plate 23 of the storage battery storage box 22 is also formed with a slit 52 only between the storage batteries 11 excluding the storage batteries 11a and 11b, and is closed between the storage batteries 11a and 11b.

この構成により、蓄電池１１ａ、１１ｂ間では、中仕切り板４１の空洞部Ｓは上下のいずれにも開放せず、蓄電池１１ａ、１１ｂ間の上下方向の通気が規制される。
一方、図６（Ｂ）に示すように、押さえ板３１については、全てスリット３１Ａが設けられる。これにより、横並びの全ての蓄電池１１、１１ａ、１１ｂ間では、中仕切り板４１の空洞部Ｓが前方に開放し、前方への通気は許容される。 With this configuration, between the storage batteries 11a and 11b, the hollow portion S of the partition plate 41 is not opened to the upper and lower sides, and the vertical ventilation between the storage batteries 11a and 11b is restricted.
On the other hand, as shown in FIG. 6B, all the presser plates 31 are provided with slits 31A. Thereby, between all the storage batteries 11, 11a, 11b arranged side by side, the cavity S of the partition plate 41 opens forward, and forward ventilation is allowed.

本構成によれば、一般に、左右両端側の蓄電池１１ほど外空間へ放熱し易いので、左右両端側の蓄電池１１ａ、１１ｂ間の上下方向の通気を規制することにより、蓄電池１１ａ、１１ｂの放熱を抑えることができる。これにより、隣の蓄電池１１との温度差を抑えることができ、左右に隣り合う蓄電池１１の均熱化を図り易くなる。
また、前方への通気は許容されるので、蓄電池１１前後の温度の偏りを抑えることができ、蓄電池１１単体の均熱化を図り易くなる。 In general, according to this configuration, the storage battery 11 on both the left and right ends is easier to radiate heat to the outer space. Therefore, by restricting the ventilation in the vertical direction between the storage batteries 11a and 11b on the left and right ends, the heat dissipation of the storage batteries 11a and 11b is performed. Can be suppressed. Thereby, the temperature difference with the adjacent storage battery 11 can be suppressed, and it becomes easy to attain equalization of the storage battery 11 adjacent to right and left.
In addition, since ventilation to the front is allowed, it is possible to suppress a temperature deviation before and after the storage battery 11, and it is easy to equalize the temperature of the storage battery 11 alone.

図７は、最下段の蓄電池収納箱２２を模式的に示した図であり、図７（Ａ）は上方から見た図、図７（Ｂ）は前方から見た図、図７（Ｃ）は下方から見た図である。
図７に示すように、最下段の蓄電池収納箱２２は、図６に示した構成に加え、更に、左右両端側の蓄電池１１ｃ、１１ｃ間の押さえ板３１（図６中、符号３１Ｘで示す）にはスリット３１Ａを形成していない構成である。
この構成によれば、最下段の蓄電池収納箱２２については、蓄電池１１ｃ、１１ｄの放熱を更に抑制することができる。図５に示すように、蓄電池１１ｃ、１１ｄは、左右外側に加えて下方にも放熱し易い位置にあるため、一般に温度低下が著しい。このため、蓄電池１１ｃ、１１ｄの放熱を更に抑制することにより、上段の蓄電池１１（１１ａ、１１ｂを含む）との温度差を低減し、均熱化を図り易くなる。 7 is a diagram schematically showing the lowermost storage battery storage box 22, FIG. 7 (A) is a view from above, FIG. 7 (B) is a view from the front, FIG. 7 (C). Is a view from below.
As shown in FIG. 7, the storage battery storage box 22 in the lowermost stage is further provided with a holding plate 31 between the storage batteries 11c and 11c on the left and right ends (indicated by reference numeral 31X in FIG. 6) in addition to the configuration shown in FIG. In this configuration, the slit 31A is not formed.
According to this structure, about the storage battery storage box 22 of the lowest stage, the thermal radiation of the storage batteries 11c and 11d can further be suppressed. As shown in FIG. 5, since the storage batteries 11c and 11d are in a position where heat is easily radiated downward in addition to the left and right outer sides, the temperature drop is generally remarkable. For this reason, by further suppressing the heat radiation of the storage batteries 11c and 11d, the temperature difference from the upper storage battery 11 (including 11a and 11b) is reduced, and it becomes easy to achieve soaking.

この構成によれば、蓄電池１１間の通気を促して放熱性を向上しつつ、左右両端側及び下段側の蓄電池１１ａ〜１１ｄの放熱を抑制し、各蓄電池１１の均熱化を図り易くなる。
しかも、本構成では、底板２３や上板２４や押さえ板３１のスリット５１、５２、３１Ａの有無により、所定の蓄電池１１ａ〜１１ｄの放熱を抑制するので、中仕切り板４１を全て共通にすることができる。この中仕切り板４１は、開口部ＫＡ〜ＫＤを有しない構成と比べて軽量であるため、組電池１０の軽量化に有利である。 According to this configuration, while promoting the ventilation between the storage batteries 11 to improve the heat dissipation, the heat dissipation of the storage batteries 11a to 11d on the left and right ends and the lower side is suppressed, and it becomes easy to equalize the temperature of each storage battery 11.
In addition, in this configuration, the heat release of the predetermined storage batteries 11a to 11d is suppressed depending on the presence or absence of the slits 51, 52, and 31A of the bottom plate 23, the upper plate 24, and the pressing plate 31, so that all the partition plates 41 are made common. Can do. Since the partition plate 41 is lighter than the configuration without the openings KA to KD, it is advantageous for reducing the weight of the battery pack 10.

なお、本実施例では、底板２３や上板２４や押さえ板３１のスリット５１、５２、３１Ａの有無により、所定の蓄電池１１ａ〜１１ｄの放熱を抑制する場合を説明したが、中仕切り板４１の開口部ＫＡ〜ＫＤを適宜に閉塞した構造にすることによって、上記の通気を規制するように構成しても良い。この場合、底板２３や上板２４や押さえ板３１は全て共通にしても良いし、上記と同様のままでも良い。   In addition, although the present Example demonstrated the case where the heat release of the predetermined storage batteries 11a-11d was suppressed by the presence or absence of the slits 51, 52, and 31A of the bottom plate 23, the upper plate 24, and the pressing plate 31, the partition plate 41 You may comprise so that said ventilation | gas_flowing may be controlled by making it the structure which obstruct | occluded opening part KA-KD suitably. In this case, the bottom plate 23, the upper plate 24, and the pressing plate 31 may all be common or may be the same as described above.

つまり、第２実施例の最下段は、第１実施例の最下段の蓄電池収納箱２２に対し、更に、底板２３や上板２４のスリット５１、５２を無くした構造とされる。 (Second embodiment)

That is, the lowermost stage of the second embodiment has a structure in which the bottom plate 23 and the slits 51 and 52 of the upper plate 24 are further eliminated from the lowermost storage battery storage box 22 of the first embodiment.

この構成によれば、最下段の全ての蓄電池１１（蓄電池１１ｃ、１１ｄを含む）の放熱を抑えつつ、残りの蓄電池１１の放熱性を向上することができる。この第２実施例は、最下段の蓄電池１１と上段の蓄電池１１との温度差が大きく、且つ、蓄電池１１ｃ、１１ｄの温度上昇が抑えられる環境の場合に、例えば、最下段の蓄電池１１下方の空間の温度が比較的低く、下方ほど温度低下が著しい設置環境の場合に、放熱性の向上と各蓄電池１１の均熱化を図り易くなる。
なお、第２実施例においても、最下段の中仕切り板４１の開口部ＫＡ〜ＫＤを適宜に閉塞した構造にすることによって、上記の通気を規制するように構成しても良い。 According to this configuration, the heat dissipation of the remaining storage batteries 11 can be improved while suppressing the heat dissipation of all the storage batteries 11 (including the storage batteries 11c and 11d) at the lowest stage. In the second embodiment, in the case where the temperature difference between the lower storage battery 11 and the upper storage battery 11 is large and the temperature rise of the storage batteries 11c and 11d is suppressed, for example, the lower storage battery 11 is located below the lower storage battery 11. In an installation environment in which the temperature of the space is relatively low and the temperature lowers significantly in the lower part, it is easy to improve heat dissipation and equalize the temperature of each storage battery 11.
In the second embodiment, the above-described ventilation may be restricted by appropriately closing the openings KA to KD of the lowermost partition plate 41.

FIG. 12 is a diagram schematically showing the assembled battery 10 according to the tenth example from the front.
In the tenth embodiment, only ventilation from below between all the storage batteries 11 (including the storage batteries 11c and 11d) at the lowermost stage is restricted, and ventilation of the remaining storage batteries 11 in the vertical and front-rear directions is permitted.
According to this configuration, since the air in the lower space of the lowermost storage batteries 11, 11c, 11d does not enter between the storage batteries 11, only the influence of the air temperature in the lower space is mainly suppressed. Thereby, with respect to the ninth embodiment, it is possible to finely adjust the heat radiation of the lowermost storage batteries 11, 11 c, 11 d, etc., and to improve heat dissipation and equalize the temperature of each storage battery 11 according to the installation environment.

Just do it.

以上説明したように、本実施の蓄電池収納箱２２は、蓄電池１１の収納空間を左右に仕切る複数の中仕切り板４１を備え、底板２３と上板２４と中仕切り板４１の少なくともいずれかに、予め定めた蓄電池１１間に通気路５５を形成する開口部（スリット５１、５２、ＫＡ〜ＫＤ）を設け、残りの蓄電池１１間への通気は遮断するので、予め定めた蓄電池１１の放熱性を向上し、残りの蓄電池１１の放熱を抑制することができる。このため、ファン等の強制冷却装置を使用しなくても放熱性を向上させることができ、且つ、予め定めた蓄電池１１が他の蓄電池１１よりも温度が高い場合にその温度の偏りを抑えることができる。従って、放熱性の向上と各蓄電池１１の均熱化とが可能になる。
また、ファン等の冷却装置を使用しないため、コスト低減に有利である。 As described above, the storage battery storage box 22 of the present embodiment includes a plurality of partition plates 41 that partition the storage space of the storage battery 11 to the left and right, and at least one of the bottom plate 23, the upper plate 24, and the partition plate 41, Since openings (slits 51, 52, KA to KD) for forming the air passage 55 between the predetermined storage batteries 11 are provided and ventilation between the remaining storage batteries 11 is blocked, the heat dissipation of the predetermined storage battery 11 is improved. The heat dissipation of the remaining storage battery 11 can be suppressed. For this reason, even if it does not use forced cooling devices, such as a fan, heat dissipation can be improved, and when the predetermined storage battery 11 is higher in temperature than the other storage battery 11, the bias of the temperature is suppressed. Can do. Therefore, it is possible to improve the heat dissipation and to equalize each storage battery 11.
Moreover, since a cooling device such as a fan is not used, it is advantageous for cost reduction.

また、前記予め定めた蓄電池１１間に配置される中仕切り板４１は、前後に開放する空洞部Ｓを有するので、前後方向の通気によっても放熱することができる。この前後方向の通気により、蓄電池１１の放熱性を向上したり、蓄電池１１自体の温度の均等化（均熱化）を図ったりすることができる。 The partition plate 41 disposed between the predetermined storage batteries 11 has a cavity S that opens up and down, and at least one of the bottom plate 23 and the upper plate 24 has slits 51 and 52 that communicate with the cavity S. Therefore, the hollow portion S and the slits 51 and 52 can promote ventilation in the vertical direction and efficiently dissipate heat.
Moreover, since the partition plate 41 arrange | positioned between the said predetermined storage batteries 11 has the cavity part S open | released to the front and back, it can also radiate | emit heat also by ventilation in the front-back direction. By this ventilation in the front-rear direction, the heat dissipation of the storage battery 11 can be improved, or the temperature of the storage battery 11 itself can be equalized (soaking).

また、蓄電池１１を前方から押さえるとともに中仕切り板４１の前面を覆う押さえ板３１を有し、押さえ板３１は中仕切り板４１の空洞部Ｓと連通するスリット３１Ａを有するので、簡易に前後方向への通気を行うことができる。また、従来の、スリット３１Ａを有しない押さえ板を用いることにより、簡易に前後方向への通気を遮断できる。

Can be ventilated. Further, by using a conventional pressing plate that does not have the slit 31A, ventilation in the front-rear direction can be easily blocked.
Further, since the ventilation between the remaining storage batteries 11 is blocked by at least one of the bottom plate 23, the upper plate 24, and the partition plate 41 of the storage battery storage box 22, the ventilation can be blocked with a simple configuration. Moreover, since the structure which the storage battery storage box 22 has is used, the increase in a number of parts is avoided and it is advantageous also for cost reduction.

また、左右両端に位置する蓄電池１１ａ、１１ｃとその隣の蓄電池１１ｂ、１１ｄとの間の通気が遮断されるので、側方の外部空間に放熱し易い蓄電池１１ａ〜１１ｂの著しい温度低下を抑制することができ、他の蓄電池１１との均熱化を図り易くなる。
また、最も下に位置する蓄電池１１（１１ｃ、１１ｄを含む）間の通気が遮断されるので、下方の外部空間に放熱し易い蓄電池１１の著しい温度低下を抑制することができ、他の蓄電池１１との均熱化を図り易くなる。 Moreover, since the ventilation | gas_flowing between the storage batteries 11a and 11c located in both right and left ends and the adjacent storage batteries 11b and 11d is interrupted | blocked, the remarkable temperature fall of the storage batteries 11a-11b which are easy to radiate | emit heat to a side external space is suppressed. It becomes easy to achieve soaking with other storage batteries 11.
In addition, since the ventilation between the storage batteries 11 (including 11c and 11d) located at the bottom is blocked, it is possible to suppress a significant temperature drop of the storage battery 11 that easily radiates heat to the lower external space. It becomes easy to achieve soaking.
