ところで、電池パックにおいては、二次電池の劣化を抑制するために、二次電池を効率よく温度調節することが望まれている。
本発明の目的は、二次電池が収容されるケースを利用して流路を区画しつつ、二次電池を効率よく温度調節することができる電池パックを提供することにある。
By the way, in a battery pack, in order to suppress deterioration of a secondary battery, it is desired to adjust the temperature of the secondary battery efficiently.
An object of the present invention is to provide a battery pack capable of efficiently adjusting the temperature of a secondary battery while partitioning a flow path using a case in which the secondary battery is accommodated.

上記課題を解決するため、請求項1に記載の発明は、ケースと、端子が突設された端子面を有し、該端子面を含む側面が前記ケースの内面から離間した態様で前記ケースに収容された二次電池と、前記二次電池の側面と、該側面と対向する前記ケースの内面との間に区画された流路と、前記二次電池と隣り合うとともに、前記流路と連通する温調用流路と、を備え、熱媒体が前記温調用流路を流通することで前記二次電池の温度調節が行われる電池パックであって、前記二次電池の前記側面と前記ケースの内面との間であり、かつ、前記流路から前記端子に至る経路上には、前記端子に前記熱媒体が供給されることを抑制する抑制部材が設けられることを要旨とする。   In order to solve the above problems, the invention according to claim 1 includes a case and a terminal surface on which a terminal protrudes, and the side surface including the terminal surface is separated from the inner surface of the case. A secondary battery housed therein, a side surface of the secondary battery, a flow path defined between the inner surface of the case facing the side surface, and adjacent to the secondary battery, and in communication with the flow path A temperature control flow path, and a temperature of the secondary battery is adjusted by circulating a heat medium through the temperature control flow path, wherein the side surface of the secondary battery and the case The gist is that a suppression member that suppresses the supply of the heat medium to the terminal is provided on a path between the inner surface and the flow path to the terminal.

これによれば、流路を流通する熱媒体は、抑制部材に抑制されて端子に供給されにくい。すなわち、抑制部材により端子面とケースの内面の間の領域に熱媒体が供給されることが抑制されている。このため、流路を流れる熱媒体が、温調用流路以外の領域に流入しにくく、結果として、温調用流路に熱媒体が流入しやすくなり、温調用流路を流通する熱媒体の流量は、抑制部材を設けない場合に比べて増加する。したがって、二次電池が収容されるケースを利用して流路を区画しつつ、二次電池を効率よく温度調節効率することができる。   According to this, the heat medium which distribute | circulates a flow path is suppressed by the suppression member, and is hard to be supplied to a terminal. That is, the suppression member prevents the heat medium from being supplied to the region between the terminal surface and the inner surface of the case. For this reason, it is difficult for the heat medium flowing through the flow path to flow into the region other than the temperature control flow path, and as a result, the heat medium easily flows into the temperature control flow path, and the flow rate of the heat medium flowing through the temperature control flow path Increases compared to the case where no suppression member is provided. Therefore, the temperature of the secondary battery can be efficiently controlled while partitioning the flow path using the case in which the secondary battery is accommodated.

また、前記抑制部材は、前記端子面と前記ケースの内面との間に設けられた絶縁性熱伝導部材であってもよい。
これによれば、端子で発した熱は、絶縁性熱伝導部材を介して放熱される。二次電池が発熱するときには、端子の温度が高くなる。このため、端子の発した熱を絶縁性熱伝導部材で放熱することで、二次電池を効率よく冷却することができる。
Further, the suppressing member may be an insulating heat conductive member provided between the terminal surface and the inner surface of the case.
According to this, the heat generated at the terminal is dissipated through the insulating heat conducting member. When the secondary battery generates heat, the temperature of the terminal increases. For this reason, a secondary battery can be efficiently cooled by radiating the heat | fever which the terminal emitted with the insulating heat conductive member.

本発明によれば、二次電池が収容されるケースを利用して流路を区画しつつ、二次電池を効率よく温度調節することができる。   ADVANTAGE OF THE INVENTION According to this invention, a secondary battery can be temperature-controlled efficiently, dividing a flow path using the case in which a secondary battery is accommodated.

図3に示すように、電池モジュール21,22は、二次電池としての角型電池23と、角型電池23の厚み方向に隣り合うスペーサ24を交互に並設して構成されている。スペーサ24は、隣り合う角型電池23の間隔を維持するとともに、角型電池23に隣り合うように熱媒体が流通する温調用流路25を区画している。角型電池23は、底板12に載置される面と反対側の端子面23a(高さ方向一面)に端子26(正極端子及び負極端子)が突設されている。端子面23aと、天板15の基部16の内面とは、離間しており、端子面23aと基部16との間には、領域Aが区画されている。   As shown in FIG. 3, the battery modules 21 and 22 are configured by alternately arranging prismatic batteries 23 as secondary batteries and spacers 24 adjacent in the thickness direction of the prismatic batteries 23. The spacer 24 maintains a gap between the adjacent square batteries 23, and defines a temperature adjustment flow path 25 through which the heat medium flows so as to be adjacent to the square batteries 23. The square battery 23 has a terminal 26 (a positive electrode terminal and a negative electrode terminal) protruding from a terminal surface 23 a (one surface in the height direction) opposite to the surface placed on the bottom plate 12. The terminal surface 23 a and the inner surface of the base portion 16 of the top plate 15 are separated from each other, and a region A is defined between the terminal surface 23 a and the base portion 16.

図2に示すように、第1の電池モジュール21における角型電池23の幅方向(角型電池23の厚み方向及び高さ方向に直交する方向)一面(側面)と、角型電池23の幅方向一面と対向する第1の区画板17の面との間には、流路としての流入路31が形成されている。この流入路31は、温調用流路25に熱媒体を流入させる。また、角型電池23の幅方向他面(側面)と、角型電池23の幅方向他面と対向する第2の区画板18の面との間には、流路としての流出路32が形成されている。この流出路32には、温調用流路25を流通した後の熱媒体が排出される。   As shown in FIG. 2, the width direction of the rectangular battery 23 in the first battery module 21 (the direction perpendicular to the thickness direction and the height direction of the rectangular battery 23) and the width of the rectangular battery 23 are as follows. An inflow path 31 as a flow path is formed between the one surface in the direction and the surface of the first partition plate 17 facing the surface. The inflow path 31 allows the heat medium to flow into the temperature adjustment path 25. In addition, an outflow path 32 as a flow path is provided between the other side surface (side surface) in the width direction of the prismatic battery 23 and the surface of the second partition plate 18 facing the other side surface in the width direction of the prismatic battery 23. Is formed. The heat medium after flowing through the temperature adjustment channel 25 is discharged to the outflow channel 32.

第2の電池モジュール22における角型電池23の幅方向他面と、角型電池23の幅方向他面と対向する第3の区画板19の面との間にも、流入路31が形成されている。また、第2の電池モジュール22における角型電池23の幅方向一面と、角型電池23の幅方向一面と対向する第2の区画板18の面との間にも流出路32が形成されている。   An inflow path 31 is also formed between the other surface in the width direction of the square battery 23 in the second battery module 22 and the surface of the third partition plate 19 facing the other surface in the width direction of the square battery 23. ing. In addition, an outflow path 32 is also formed between one surface in the width direction of the square battery 23 in the second battery module 22 and the surface of the second partition plate 18 facing the one surface in the width direction of the square battery 23. Yes.

各電池モジュール21,22における角型電池23の端子面23aと、天板15の基部16との間(角型電池23の側面とケース11の内面との間)に形成された領域Aには、絶縁性熱伝導部材としての、熱伝導シート33が設けられている。   In a region A formed between the terminal surface 23a of the prismatic battery 23 and the base 16 of the top plate 15 (between the side surface of the prismatic battery 23 and the inner surface of the case 11) in each of the battery modules 21 and 22. A heat conductive sheet 33 is provided as an insulating heat conductive member.

図1及び図2に示すように、熱伝導シート33は、矩形状をなしており、その短手方向の長さは、角型電池23の幅方向の長さと同一となっており、長手方向の長さは、角型電池23の並設方向一端に位置する角型電池23から、角型電池23の並設方向他端に位置する角型電池23までの長さと同一となっている。また、熱伝導シート33の厚みは、端子面23aから、天板15の基部16の内面までの長さ、すなわち、領域Aの高さと同一となっている。   As shown in FIGS. 1 and 2, the heat conductive sheet 33 has a rectangular shape, and the length in the short direction is the same as the length in the width direction of the prismatic battery 23, and the longitudinal direction. Is the same as the length from the prismatic battery 23 located at one end of the prismatic battery 23 in the juxtaposed direction to the prismatic battery 23 located at the other end of the prismatic battery 23 in the juxtaposed direction. Moreover, the thickness of the heat conductive sheet 33 is the same as the length from the terminal surface 23 a to the inner surface of the base portion 16 of the top plate 15, that is, the height of the region A.

熱伝導シート33は、絶縁性を有し、かつ、熱伝導率の高い材料から形成されている。そして、領域Aは、熱伝導シート33によって占められている。詳細にいえば、熱伝導シート33は、端子面23aの全面を覆うように設けられており、領域Aの全てが熱伝導シート33によって占められている。熱伝導シート33が領域Aの全てを占めることで、流入路31から端子26に至る経路上及び流出路32から端子26に至る経路上にも熱伝導シート33が設けられている。端子26は熱伝導シート33に入り込んでいる。そして、領域Aを介した流入路31と、流出路32との連通が熱伝導シート33によって防止されている。したがって、熱伝導シート33は、角型電池23の端子26に熱媒体が供給されることを抑制する抑制部材として機能している。本実施形態では、熱伝導シート33は、端子面23a及び基部16の内面に接しており、端子面23aと基部16は熱伝導シート33を介して熱的に結合されている。   The heat conductive sheet 33 is made of a material having insulating properties and high heat conductivity. The region A is occupied by the heat conductive sheet 33. Specifically, the heat conductive sheet 33 is provided so as to cover the entire surface of the terminal surface 23 a, and the entire region A is occupied by the heat conductive sheet 33. Since the heat conductive sheet 33 occupies the entire region A, the heat conductive sheet 33 is also provided on the path from the inflow path 31 to the terminal 26 and on the path from the outflow path 32 to the terminal 26. The terminal 26 enters the heat conductive sheet 33. Then, the communication between the inflow path 31 and the outflow path 32 through the region A is prevented by the heat conductive sheet 33. Therefore, the heat conductive sheet 33 functions as a suppressing member that suppresses the supply of the heat medium to the terminal 26 of the square battery 23. In the present embodiment, the heat conductive sheet 33 is in contact with the terminal surface 23 a and the inner surface of the base portion 16, and the terminal surface 23 a and the base portion 16 are thermally coupled via the heat conductive sheet 33.

以下、本実施形態の電池モジュール21の作用について説明する。
角型電池23の温度調節を行うときには、流入路31に温度調節装置(図示せず)によって加熱又は冷却された熱媒体が供給される。流入路31に供給された熱媒体は、各温調用流路25に流入し、角型電池23の温度調節を行う。このとき、領域Aを介した流入路31と、流出路32との連通が熱伝導シート33によって防止されているため、流入路31を流通する熱媒体は、領域Aに流入しない。また、角型電池23が発熱するとき(放電時及び充電時)には、端子26の温度が高くなる。端子26で発した熱は、熱伝導シート33を伝わり、天板15に放熱される。
Hereinafter, the operation of the battery module 21 of the present embodiment will be described.
When the temperature of the prismatic battery 23 is adjusted, a heat medium heated or cooled by a temperature adjusting device (not shown) is supplied to the inflow path 31. The heat medium supplied to the inflow path 31 flows into each temperature adjustment flow path 25 and adjusts the temperature of the prismatic battery 23. At this time, since the communication between the inflow path 31 and the outflow path 32 through the region A is prevented by the heat conductive sheet 33, the heat medium flowing through the inflow channel 31 does not flow into the region A. Further, when the prismatic battery 23 generates heat (during discharging and charging), the temperature of the terminal 26 increases. The heat generated at the terminal 26 is transmitted through the heat conductive sheet 33 and is radiated to the top plate 15.

したがって、上記実施形態によれば、以下のような効果を得ることができる。
(1)角型電池23の端子面23aと、天板15の基部16の内面との間には、熱伝導シート33が設けられており、端子面23aと基部16の内面の間の領域Aに熱媒体が供給されることが抑制され、熱伝導シート33によって端子26に熱媒体が供給されることが抑制されている。このため、ケース11内では、流入路31及び流出路32を除いた温調用流路25以外の領域に熱媒体が流入しにくく、結果として、温調用流路25に熱媒体が流入しやすくなり、温調用流路25を流通する熱媒体の流量は、熱伝導シート33を設けない場合に比べて増加する。したがって、ケース11を利用して流入路31及び流出路32を区画しつつ、角型電池23を効率よく温度調節効率することができる。
Therefore, according to the above embodiment, the following effects can be obtained.
(1) A heat conductive sheet 33 is provided between the terminal surface 23 a of the square battery 23 and the inner surface of the base portion 16 of the top plate 15, and a region A between the terminal surface 23 a and the inner surface of the base portion 16. The supply of the heat medium to the terminal 26 is suppressed by the heat conductive sheet 33. For this reason, in the case 11, it is difficult for the heat medium to flow into a region other than the temperature adjustment flow path 25 excluding the inflow path 31 and the outflow path 32, and as a result, the heat medium easily flows into the temperature adjustment flow path 25. The flow rate of the heat medium flowing through the temperature adjustment flow path 25 increases as compared with the case where the heat conductive sheet 33 is not provided. Therefore, the temperature of the prismatic battery 23 can be efficiently controlled while partitioning the inflow path 31 and the outflow path 32 using the case 11.

(2)抑制部材として熱伝導シート33を用いている。このため、端子26で発した熱は、熱伝導シート33を介して天板15に放熱される。角型電池23が発熱するときには、端子26の温度が高くなる。このため、端子26の温度を熱伝導シート33で放熱することで、角型電池23を効率よく冷却することができる。   (2) The heat conductive sheet 33 is used as the suppressing member. For this reason, the heat generated at the terminal 26 is radiated to the top plate 15 via the heat conductive sheet 33. When the prismatic battery 23 generates heat, the temperature of the terminal 26 increases. For this reason, the rectangular battery 23 can be efficiently cooled by radiating the temperature of the terminal 26 with the heat conductive sheet 33.

(3)ケース11の一部を構成する天板15を利用して流入路31及び流出路32を区画している。このため、流入路31及び流出路32を区画するための部材を別途設ける必要がなく、部品点数が削減される。   (3) The inflow path 31 and the outflow path 32 are partitioned using the top plate 15 that constitutes a part of the case 11. For this reason, it is not necessary to separately provide a member for partitioning the inflow path 31 and the outflow path 32, and the number of parts is reduced.

なお、上記実施形態は、以下のように変更してもよい。
○ 実施形態において、抑制部材として、絶縁性熱伝導部材以外を用いてもよい。例えば、図4に示すように、端子面23aと天板15の基部16の間に区画された領域Aに、角型電池23の並設方向全体に延びる一対の板状部材41,42を設けてもよい。一対の板状部材41,42は、各角型電池23の両端子26を外側から挟むように設けられている。板状部材41は、流入路31から端子26に至る経路上に設けられている。板状部材42は、流出路32から端子26に至る経路上に設けられている。
In addition, you may change the said embodiment as follows.
In embodiment, you may use other than an insulating heat conductive member as a suppression member. For example, as shown in FIG. 4, a pair of plate-like members 41, 42 extending in the entire parallel direction of the prismatic batteries 23 is provided in a region A defined between the terminal surface 23 a and the base 16 of the top plate 15. May be. The pair of plate-like members 41 and 42 are provided so as to sandwich both terminals 26 of each square battery 23 from the outside. The plate-like member 41 is provided on a path from the inflow path 31 to the terminal 26. The plate member 42 is provided on a path from the outflow path 32 to the terminal 26.
