本発明に係る組電池１は、複数の単電池を電気的に接続して１つのパッケージとした電池モジュール２を、複数電気的に接続して構成されるものである。   The assembled battery 1 according to the present invention is configured by electrically connecting a plurality of battery modules 2 in which a plurality of single cells are electrically connected to form one package.

第１本実施形態に係る組電池１は、図１〜３に示すように、複数の電池モジュール２と、これらの電池モジュール２が固定される第１固縛部材３と、第１固縛部材３と共に電池モジュール２を挟んで挟持する第２固縛部材４と、固縛部材３，４の外側を覆う２枚のラミネート部材５Ａ，５Ｂと、を有している。   As shown in FIGS. 1 to 3, the assembled battery 1 according to the first embodiment includes a plurality of battery modules 2, a first securing member 3 to which these battery modules 2 are fixed, and a first securing member. 3, a second securing member 4 sandwiching the battery module 2 with the two, and two laminate members 5 </ b> A and 5 </ b> B covering the outside of the securing members 3 and 4.

第１固縛部材３は矩形の板形状の部材であり、例えば８つの電池モジュール２が設置されるが、電池モジュール２の数は限定されない。第１固縛部材３には、端部に複数の固縛用ブラケット７が形成されており、車両の車体に固定できる構造となっている。   The first securing member 3 is a rectangular plate-shaped member, and for example, eight battery modules 2 are installed, but the number of battery modules 2 is not limited. The first lashing member 3 is formed with a plurality of lashing brackets 7 at the end, and can be fixed to the vehicle body of the vehicle.

第１固縛部材３には、それぞれの電池モジュール２が個別に固定されてバスバー８により電気的に接続され、電気的に接続される最終端には、図４に示すように電極端子９が設けられている。また、バスバー８の一部には、電気的に遮断されたセーフティープラグ１０が設けられている。このセーフティープラグ１０をセーフティーバー１１に差し込みまたは取り外すことにより、電気的に接続し、または遮断することができる。   Each battery module 2 is individually fixed to the first tying member 3 and is electrically connected by a bus bar 8, and an electrode terminal 9 is provided at the final end of the electrical connection as shown in FIG. 4. Is provided. A part of the bus bar 8 is provided with a safety plug 10 that is electrically cut off. By inserting or removing the safety plug 10 into or from the safety bar 11, it can be electrically connected or disconnected.

第２固縛部材４は矩形の板形状の部材であり、固縛用ボルト１２が収まる固縛用ボルト受け１３が形成されている（図２参照）。第１固縛部材３と第２固縛部材４の間には、固縛用ボルト受け１３を囲うように筒形状の固縛用スペーサ１４が配置され、固縛用ボルト受け１３に収まる固縛用ボルト１２が、第１固縛部材３に溶接等により固定された固縛用ナット１５と螺合する。これにより、第１固縛部材３と第２固縛部材４とが締結されるとともに電池モジュール２が挟持される。また、スペーサ１４が設けられることにより、電池モジュール２に過度の荷重が掛かることを防止できる。また、固縛用ボルト１２が固縛用ボルト受け１３に収まる構造であるため、第２固縛部材４の外側表面に突出部が形成されず、ラミネート部材に損傷を与えることなくラミネート部材により覆うことができる。   The second lashing member 4 is a rectangular plate-shaped member, and is formed with a lashing bolt receiver 13 in which the lashing bolt 12 is accommodated (see FIG. 2). Between the first lashing member 3 and the second lashing member 4, a cylindrical lashing spacer 14 is disposed so as to surround the lashing bolt receiver 13, and the lashing that fits in the lashing bolt receiver 13 The bolt 12 is screwed into a lashing nut 15 fixed to the first lashing member 3 by welding or the like. Thereby, the 1st securing member 3 and the 2nd securing member 4 are fastened, and the battery module 2 is clamped. Further, by providing the spacer 14, it is possible to prevent an excessive load from being applied to the battery module 2. In addition, since the lashing bolt 12 is configured to fit in the lashing bolt receiver 13, no protruding portion is formed on the outer surface of the second lashing member 4, and the laminate member is covered without damaging the laminate member. be able to.

なお、スペーサ１４は筒形状でなくてもよく、固縛用ボルト１２の近傍に柱状の部材を設けたり、または隣接する固縛用ボルト１２の間に亘って伸延する部材を設けてもよい。   The spacer 14 may not be cylindrical, and a columnar member may be provided in the vicinity of the lashing bolt 12 or a member extending between the adjacent lashing bolts 12 may be provided.

また、固縛用ボルト受け１３ではなく、図５に示すように、テーパ形状の穴部およびボルト１２’を設けてもよい。   Further, instead of the securing bolt receiver 13, a tapered hole and a bolt 12 'may be provided as shown in FIG.

第１固縛部材３および第２固縛部材４に挟まれる電池モジュール２と固縛部材３，４との間は、接着剤や両面テープにより固定される。また、固縛部材３，４と電池モジュール２との間の摩擦力により保持してもよい。   The battery module 2 sandwiched between the first lashing member 3 and the second lashing member 4 and the lashing members 3 and 4 are fixed by an adhesive or a double-sided tape. Moreover, you may hold | maintain with the frictional force between the securing members 3 and 4 and the battery module 2. FIG.

ラミネート部材５は、アルミ薄膜の両面に樹脂の層が形成された部材である。第１固縛部材３および第２固縛部材４に挟持された電池モジュール２は、この２枚のラミネート部材５Ａ，５Ｂにより挟まれ、２枚のラミネート部材５Ａ，５Ｂの端部同士を熱融着することにより密封される。この際、電極端子９、セーフティープラグ１０および固縛用ブラケット７が外部に導出されて密封される。   The laminate member 5 is a member in which a resin layer is formed on both surfaces of an aluminum thin film. The battery module 2 sandwiched between the first securing member 3 and the second securing member 4 is sandwiched between the two laminate members 5A and 5B, and the ends of the two laminate members 5A and 5B are heat-fused. Sealed by wearing. At this time, the electrode terminal 9, the safety plug 10, and the securing bracket 7 are led out and sealed.

また、ラミネート部材の一部には切欠き１５が形成される（図１参照）。この切欠き１５は、電池に不具合が生じ、密封されたラミネート部材５の内部の圧力が上昇した際に、破れて内部のガスを外部に放出するための安全弁の役割を果たす。この切欠き５は、本発明に係る組電池１を車体に設置した際に、車外に導出されるダクトに連結されることが好ましい。   Further, a notch 15 is formed in a part of the laminate member (see FIG. 1). The notch 15 functions as a safety valve for breaking the battery and releasing the internal gas to the outside when a malfunction occurs in the battery and the internal pressure of the sealed laminate member 5 rises. This notch 5 is preferably connected to a duct led out of the vehicle when the assembled battery 1 according to the present invention is installed on the vehicle body.

また、安全弁として、所定の圧力で開通する弁や、所定の圧力で破壊されるラプチャディスクをラミネート部材５に設けることもできる。   Further, as the safety valve, the laminate member 5 can be provided with a valve that opens at a predetermined pressure or a rupture disk that is destroyed at a predetermined pressure.

第１固縛部材３および第２固縛部材４は、軽量で熱伝導性の高いアルミ、導電性がなく短絡を防止できるアルマイト処理されたアルミ、耐食性に優れたステンレス、または鉄等の種々の部材により作製することができるが、車体側に固定される第１固縛部材３の熱伝導性が第２固縛部材４よりも高いことが好ましい。   The first lashing member 3 and the second lashing member 4 are made of various materials such as aluminum which is lightweight and has high thermal conductivity, aluminum which has no conductivity and which can prevent short circuit, stainless steel which is excellent in corrosion resistance, or iron. Although it can produce with a member, it is preferable that the heat conductivity of the 1st securing member 3 fixed to the vehicle body side is higher than the 2nd securing member 4. FIG.

例えば、第１固縛部材３をアルミ、第２固縛部材４を鉄とすることにより、第１固縛部材３側から電池により発生する熱を放熱することができ、車内側となる第２固縛部材４からの放熱を防止することができる。これにより、車内に組電池１を設置しても車内の組電池１による温度上昇を防止することができる。   For example, when the first lashing member 3 is made of aluminum and the second lashing member 4 is made of iron, the heat generated by the battery from the first lashing member 3 side can be radiated, and the second inside the vehicle. Heat dissipation from the lashing member 4 can be prevented. Thereby, even if it installs the assembled battery 1 in a vehicle, the temperature rise by the assembled battery 1 in a vehicle can be prevented.

また、例えば第２固縛部材４の形状を板形状ではなく貫通孔が設けられたフレーム形状とすることにより、第２固縛部材４の熱伝導性を低下させ、第１固縛部材３側から放熱させることもできる。   Further, for example, the shape of the second lashing member 4 is not a plate shape but a frame shape in which a through hole is provided, so that the thermal conductivity of the second lashing member 4 is reduced and the first lashing member 3 side is reduced. It is possible to dissipate heat.

上述のように構成された組電池１は、図７に示すように、固縛用ブラケット７により、車内やトランクルームのフロアカーペットとフロアパネルの間に固定される。この際、第１固縛部材３側がフロアパネル側となり、第２固縛部材４側が室内側となる。   As shown in FIG. 7, the assembled battery 1 configured as described above is fixed between a floor carpet and a floor panel in a vehicle or a trunk room by a securing bracket 7. At this time, the first lashing member 3 side is the floor panel side, and the second lashing member 4 side is the indoor side.

本実施形態に係る組電池１は、ラミネート部材５により全体が覆われて防水構造となっているため、車内やトランクルームのように水が浸入しやすい場所にも設置できる。   Since the assembled battery 1 according to this embodiment is entirely covered with the laminate member 5 and has a waterproof structure, it can be installed in a place where water can easily enter, such as in a car or a trunk room.

また、部材の隙間等を密封する場合と比較して、ラミネート部材５を用いて全体を纏めて密封することができるため、容易に密封構造を実現でき、またコストを削減できる。   Moreover, since the whole can be sealed together using the laminate member 5, compared with the case where the gaps between the members and the like are sealed, the sealing structure can be easily realized and the cost can be reduced.

また、電池モジュール２が固縛部材３，４に個別に固定されているため放熱面積が広く、冷却空気を強制的に送る冷却システムが不要となり、小型化、軽量化およびコストの削減が可能となる。   In addition, since the battery module 2 is individually fixed to the lashing members 3 and 4, the heat radiation area is wide, and a cooling system for forcibly sending cooling air is not required, which can be reduced in size, weight, and cost. Become.

また、セーフティープラグ１０が設けられているため、取り付け等の作業時に電流を遮断でき、安全に作業をすることができる。   Further, since the safety plug 10 is provided, the current can be cut off during work such as attachment, and the work can be performed safely.

また、電池モジュール２が固縛部材３，４に個別に固定されているため、組電池１が薄型で構成され、図６に示す従来の組電池２０のように車両のフロアパネルの形状に大きな変更をさせずに、搭載することができる（図７参照）。   Further, since the battery module 2 is individually fixed to the lashing members 3 and 4, the assembled battery 1 is configured to be thin, and the shape of the vehicle floor panel is large as in the conventional assembled battery 20 shown in FIG. It can be mounted without changing (see FIG. 7).

また、第１固縛部材３と第２固縛部材４の間にスペーサ１４が設けられているため、例えば組電池１を車内に設置した際に乗員が踏んでもその荷重をスペーサ１４で受けることができ、電池モジュール２を保護することができる。   Moreover, since the spacer 14 is provided between the 1st lashing member 3 and the 2nd lashing member 4, even if a passenger | crew steps on, for example, when installing the assembled battery 1 in a vehicle, the load is received by the spacer 14. The battery module 2 can be protected.

＜第２実施形態＞
図８は第２実施形態に係る組電池の断面図である。なお、第１実施形態と同一の構造を有する部材には同一の符号を付し、説明を省略する。 Second Embodiment
FIG. 8 is a cross-sectional view of the assembled battery according to the second embodiment. In addition, the same code | symbol is attached | subjected to the member which has the same structure as 1st Embodiment, and description is abbreviate | omitted.

第２の実施形態は、図８に示すように、固縛部材３，４とラミネート部材５の間に断熱材１６が設けられることのみが第１実施形態と異なる。   As shown in FIG. 8, the second embodiment differs from the first embodiment only in that a heat insulating material 16 is provided between the securing members 3, 4 and the laminate member 5.

第２実施形態では、第１固縛部材３とラミネート部材５Ｂの間、および第２固縛部材４とラミネート部材５Ａの間に断熱材１６が設けられる。断熱材１６の材料は、例えばプラスチック等を用いることができる。   In the second embodiment, a heat insulating material 16 is provided between the first lashing member 3 and the laminate member 5B and between the second lashing member 4 and the laminate member 5A. As the material of the heat insulating material 16, for example, plastic can be used.

なお、断熱材１６は、第１固縛部材３とラミネート部材５Ａの間のみ、または第２固縛部材４とラミネート部材５Ｂの間のみとすることもでき、組電池１’を設置する条件に応じて放熱の方向を任意に設定できる。   The heat insulating material 16 can be provided only between the first lashing member 3 and the laminate member 5A or only between the second lashing member 4 and the laminate member 5B. Accordingly, the direction of heat dissipation can be set arbitrarily.

第１固縛部材３側と第２固縛部材４側の両側に断熱材１６を設ける場合や、第２固縛部材４側のみに断熱材１６を設ける場合には、室内側への放熱を防止できるため、例えば電池からの熱が漏れて車両の空調に影響を及ぼす場所に設置する場合に効果的である。   When the heat insulating material 16 is provided on both sides of the first lashing member 3 side and the second lashing member 4 side, or when the heat insulating material 16 is provided only on the second lashing member 4 side, heat radiation to the indoor side is performed. For example, it is effective when installed in a place where the heat from the battery leaks and affects the air conditioning of the vehicle.

また、空調に影響を与えないトランクルームでは、第１固縛部材３側にのみ断熱材１６を設けることにより、トランクルームに放熱させることもできる。   Further, in the trunk room that does not affect the air conditioning, heat can be radiated to the trunk room by providing the heat insulating material 16 only on the first tying member 3 side.

＜第３実施形態＞

第３実施形態は、図９に示すように、電極端子９、セーフティープラグ１０および固縛用ブラケット７がラミネート部材５の一側のみから導出されている。このような構造とすることにより、電極端子９、セーフティープラグ１０および固縛用ブラケット７が導出される側のみが開いた袋状のラミネート部材を用いて密封することができ、熱融着する部位が少なくなるため、密封構造を容易かつ確実に実現できる。   In the third embodiment, as shown in FIG. 9, the electrode terminal 9, the safety plug 10, and the securing bracket 7 are led out from only one side of the laminate member 5. By adopting such a structure, the electrode terminal 9, the safety plug 10 and the securing bracket 7 can be sealed using a bag-like laminate member that is open only on the side where the lead-out bracket 7 is led out. Therefore, the sealing structure can be realized easily and reliably.

なお、本発明は上述した実施の形態に限定されるものではなく、特許請求の範囲の範囲内で種々改変することができる。例えば、車両の床下やトランクルーム以外の場所に設置することもでき、また車両以外の用途にも使用することができる。   The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims. For example, it can also be installed in places other than the floor of a vehicle or a trunk room, and can also be used for purposes other than vehicles.
