本発明は、ケースに複数の電池を内蔵する電源装置に関し、とくに車両用に最適な電源装置に関する。   The present invention relates to a power supply device including a plurality of batteries in a case, and more particularly to a power supply device optimal for a vehicle.

ケースに複数の電池を収納する電源装置は、自動車を走行させるモーターの駆動に使用される。この電源装置は、多数の電池を直列に接続して出力電圧を高くしている。駆動モーターの出力を大きくするためである。この種の電源装置は、大電流で充放電するときに、電池の温度が高くなる。電池は温度が高くなると、電気的な性能が低下することに加えて、劣化が甚だしく、寿命が短くなる。この弊害を避けるために、電池に冷却用の空気を強制送風して冷却する技術が開発されている。（特許文献１ないし４参照）
特開平３−１５５０５８号公報 特開２００１−６０４６５号公報 実開昭６０−１８７４５６号公報 特開平８−２５５６３７号公報 A power supply device that houses a plurality of batteries in a case is used to drive a motor that drives an automobile. In this power supply device, a large number of batteries are connected in series to increase the output voltage. This is to increase the output of the drive motor. When this type of power supply device is charged and discharged with a large current, the temperature of the battery increases. As the temperature of the battery increases, the electrical performance decreases and, in addition, the battery deteriorates significantly and its life is shortened. In order to avoid this harmful effect, a technique for cooling the battery by forcibly blowing cooling air has been developed. (See Patent Documents 1 to 4)
Japanese Patent Laid-Open No. 3-1555058 JP 2001-60465 A Japanese Utility Model Publication No. 60-187456 JP-A-8-255637

これ等の公報に記載される電源装置は、強制送風する空気で電池を冷却する。しかしながら、これ等の公報に記載されるように、電池に空気を強制送風して冷却すると、空気に含まれるホコリ、湿気、塩分等が電池を劣化させて寿命を短くする。とくに、金属部分に錆が発生して寿命が短くなる。ホコリや湿気を含む空気が強制送風されると、電池の表面にホコリが付着し、付着したホコリに湿気が結露して湿潤状態となって金属部分、たとえば電極部分等を腐食させる。さらに、空気に塩分が含まれると、湿潤な部分に塩分が含まれて、金属部分に腐食が加速される。   The power supply device described in these publications cools the battery with forced air. However, as described in these publications, when air is forcedly blown into the battery and cooled, dust, moisture, salt, and the like contained in the air deteriorate the battery and shorten its life. In particular, the rust is generated in the metal part and the life is shortened. When air containing dust or moisture is forcibly blown, dust adheres to the surface of the battery, moisture condenses on the attached dust and becomes wet, and corrodes metal parts such as electrode parts. Further, when salt is contained in the air, salt is contained in the wet portion, and corrosion of the metal portion is accelerated.

本発明は、このような欠点を解決することを目的に開発されたものである。本発明の重要な目的は、電池を強制的に冷却しながら、冷却空気によって電池寿命が短くなるのを有効に防止できる電源装置を提供することにある。   The present invention has been developed for the purpose of solving such drawbacks. An important object of the present invention is to provide a power supply apparatus that can effectively prevent a battery life from being shortened by cooling air while forcibly cooling the battery.

本発明の電源装置は、電池１に冷却用放熱フィン７を連結して、この冷却用放熱フィン７を冷却室５に表出し、冷却用放熱フィン７を冷却室５の冷却媒体で冷却して電池１を冷却することができる。   In the power supply device of the present invention, the cooling radiating fin 7 is connected to the battery 1, the cooling radiating fin 7 is exposed to the cooling chamber 5, and the cooling radiating fin 7 is cooled by the cooling medium in the cooling chamber 5. The battery 1 can be cooled.

本発明の電源装置は、冷却室５に冷却空気を強制送風して電池１を冷却することができる。また、本発明の電源装置は、冷却室５に冷却液を循環させて電池１を冷却することができる。さらにまた、本発明の電源装置は、冷却室５に絶縁油を充填し、この絶縁油を冷却して電池１を冷却することができる。   The power supply device of the present invention can cool the battery 1 by forcibly blowing cooling air into the cooling chamber 5. In addition, the power supply device of the present invention can cool the battery 1 by circulating a coolant in the cooling chamber 5. Furthermore, the power supply device of the present invention can cool the battery 1 by filling the cooling chamber 5 with insulating oil and cooling the insulating oil.

本発明の請求項７の電源装置は、複数の電池１を、上端を接続端子１５とする垂直姿勢で、一部をケース２に収納している。ケース２は、下方を開口する独立閉鎖室１２を有している。電源装置は、電池１の上部をケース２の独立閉鎖室１２に挿入して、独立閉鎖室１２の開口部を電池１で閉塞して、独立閉鎖室１２を密閉構造としている。さらに、電源装置は、この独立閉鎖室１２に電池１の上部を挿入して、電池１上部の接続端子部１Ａを独立閉鎖室１２に配設しており、電池１の下部を独立閉鎖室１２の外部に配置して冷却する。   The power supply device according to claim 7 of the present invention houses a plurality of batteries 1 in a case 2 in a vertical posture with the upper ends as connection terminals 15. The case 2 has an independent closed chamber 12 that opens downward. In the power supply device, the upper part of the battery 1 is inserted into the independent closed chamber 12 of the case 2, the opening of the independent closed chamber 12 is closed with the battery 1, and the independent closed chamber 12 has a sealed structure. Further, the power supply device inserts the upper part of the battery 1 into the independent closed chamber 12, and the connection terminal portion 1 </ b> A of the upper part of the battery 1 is disposed in the independent closed chamber 12. Place outside and cool.

さらに、本発明の電源装置は、独立閉鎖室１２に隣接して、冷却空気の排気ダクト２６を設けると共に、独立閉鎖室１２と排気ダクト２６の間に排気弁２８を設けて、電池１の安全弁が開弁して排出されるガスを排気弁２８から排気ダクト２６に排出することができる。   Further, the power supply apparatus of the present invention is provided with an exhaust duct 26 for cooling air adjacent to the independent closed chamber 12 and an exhaust valve 28 between the independent closed chamber 12 and the exhaust duct 26, so that the safety valve of the battery 1 is provided. Can be discharged from the exhaust valve 28 to the exhaust duct 26.

本発明の電源装置は、電池を強制的に冷却しながら、冷却空気によって電池寿命が短くなるのを有効に防止できる特徴がある。それは、本発明の請求項１の電源装置が、ケースを非通気性の区画壁でもって、電池を収納する電池室と電池を冷却する冷却室とに区画し、冷却室を冷却媒体で冷却して、電池室の電池を冷却するようにしており、また、本発明の請求項７の電源装置が、電池の上部をケースの独立閉鎖室に挿入して独立閉鎖室の開口部を電池で閉塞して密閉構造とし、電池上部の接続端子部を独立閉鎖室に配設して、電池の下部を独立閉鎖室の外部に配置して冷却するようにしているからである。これらの構造の電源装置は、従来の装置のように、電池に強制送風して冷却する必要がないために、電池を冷却するために強制送風する空気に含まれるホコリ、湿気、塩分等が電池を劣化させて寿命を短くすることがなく、とくに、空気に含まれる水分や塩分で金属部分に錆が発生して寿命が短くなるのを極めて有効に防止でき、これによって電池寿命を著しく長くできる特徴がある。   The power supply device of the present invention has a feature that can effectively prevent the battery life from being shortened by the cooling air while forcibly cooling the battery.

This is because the connection terminal portion at the top of the battery is disposed in the independent closed chamber and the lower portion of the battery is disposed outside the independent closed chamber for cooling. Since the power supply device of these structures does not need to be forcedly cooled by cooling the battery unlike conventional devices, dust, moisture, salt, etc. contained in the air forcedly blown to cool the battery are batteries. In particular, it can effectively prevent the life of metal parts from being rusted due to moisture and salt contained in the air and shortening the service life, thereby significantly extending the battery life. There are features.

以下、本発明の実施例を図面に基づいて説明する。ただし、以下に示す実施例は、本発明の技術思想を具体化するための電源装置を例示するものであって、本発明は電源装置を以下のものに特定しない。   Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below exemplify a power supply device for embodying the technical idea of the present invention, and the present invention does not specify the power supply device as follows.

さらに、この明細書は、特許請求の範囲を理解しやすいように、実施例に示される部材に対応する番号を、「特許請求の範囲」および「課題を解決するための手段の欄」に示される部材に付記している。ただ、特許請求の範囲に示される部材を、実施例の部材に特定するものでは決してない。   Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

図１ないし図８に示す電源装置は、複数の電池１をケース２に収納している。電池１はリチウムイオン二次電池である。ただ、本発明の電源装置は、電池をリチウムイオン二次電池には特定しない。電池には、ニッケル水素電池やニッケルカドミウム電池等の充電できる全ての電池を使用できる。   The power supply apparatus shown in FIGS. 1 to 8 has a plurality of batteries 1 housed in a case 2. The battery 1 is a lithium ion secondary battery. However, the power supply device of the present invention does not specify a battery as a lithium ion secondary battery. As the battery, any rechargeable battery such as a nickel metal hydride battery or a nickel cadmium battery can be used.

図１と図２のケース２は、非通気性の区画壁３でもって、複数の電池１を収納している密閉構造の電池室４と、この電池室４の電池１を冷却する冷却室５とに区画している。区画壁３は、ケース２の底部に水平に設けられて、この上に電池１を立てる姿勢で並べている。区画壁３の上に設けている電池室４に配置される電池１は、冷却室５に熱伝導状態で配置している。図２の区画壁３は、電池１を挿入する貫通孔６を開口している。貫通孔６は、冷却用放熱フィン７で閉塞している。冷却用放熱フィン７は、上面に電池１を連結している。冷却用放熱フィン７は、電池１を熱伝導状態で冷却室５に連結する。   A case 2 in FIGS. 1 and 2 has a non-breathable partition wall 3, a battery chamber 4 having a sealed structure that houses a plurality of batteries 1, and a cooling chamber 5 that cools the batteries 1 in the battery chamber 4. It is divided into and. The partition walls 3 are provided horizontally at the bottom of the case 2 and are arranged in a posture in which the battery 1 is erected thereon. The battery 1 disposed in the battery chamber 4 provided on the partition wall 3 is disposed in the cooling chamber 5 in a thermally conductive state. The partition wall 3 in FIG. 2 opens a through hole 6 into which the battery 1 is inserted. The through hole 6 is closed with cooling heat radiation fins 7. The cooling heat radiating fin 7 connects the battery 1 to the upper surface. The cooling fins 7 connect the battery 1 to the cooling chamber 5 in a thermally conductive state.

冷却用放熱フィン７と電池１との間には、絶縁シート８を配設して、冷却用放熱フィン７と電池１とを絶縁している。絶縁シート８は、熱伝導に優れた耐熱性のあるシート、たとえばマイカ等の薄いシートである。絶縁シート８の両面には熱伝導に優れた接着剤を塗布し、この接着剤で電池１の底面に絶縁シート８を介して冷却用放熱フィン７を接続している。接着剤は、絶縁シート８の両面を電池１と冷却用放熱フィン７に広い面積で密着させて、電池１の熱を、絶縁シート８を介して冷却用放熱フィン７に効率よく伝導する。   An insulating sheet 8 is disposed between the cooling radiating fins 7 and the battery 1 to insulate the cooling radiating fins 7 from the battery 1. The insulating sheet 8 is a heat-resistant sheet excellent in heat conduction, for example, a thin sheet such as mica. An adhesive having excellent heat conduction is applied to both surfaces of the insulating sheet 8, and the cooling heat radiation fins 7 are connected to the bottom surface of the battery 1 via the insulating sheet 8 with this adhesive. The adhesive causes both surfaces of the insulating sheet 8 to be in close contact with the battery 1 and the cooling radiating fin 7 over a wide area, and efficiently conducts heat of the battery 1 to the cooling radiating fin 7 via the insulating sheet 8.

冷却用放熱フィン７は、アルミニウム等の熱伝導に優れた金属である。冷却用放熱フィン７は、区画壁３の貫通孔６に挿入できるように、外形を貫通孔６の内形よりもわずかに小さくして、上端には外周に突出する鍔７Ａを設けている。鍔７Ａの外形は、区画壁３に設けている貫通孔６よりも大きく、これを貫通孔６の上面に係止して、冷却用放熱フィン７を区画壁３から下方に抜けないように連結し、また、貫通孔６を鍔７Ａで閉塞して、電池室４を密閉構造としている。冷却用放熱フィン７の下部で冷却室５に配設される部分は、フィン形状として効率よく冷却できるようにしている。   The cooling radiating fins 7 are a metal having excellent heat conduction, such as aluminum. The cooling radiating fin 7 has an outer shape slightly smaller than the inner shape of the through-hole 6 so that it can be inserted into the through-hole 6 of the partition wall 3, and is provided with a flange 7 </ b> A projecting to the outer periphery at the upper end. The outer shape of the flange 7 </ b> A is larger than the through hole 6 provided in the partition wall 3, and this is locked to the upper surface of the through hole 6 so that the cooling radiating fins 7 are connected so as not to fall downward from the partition wall 3. Moreover, the through-hole 6 is closed with a flange 7A, and the battery chamber 4 has a sealed structure. The portion disposed in the cooling chamber 5 below the cooling fins 7 for cooling is efficiently cooled as a fin shape.

以上の電源装置は、区画壁３と冷却用放熱フィン７とを別部品として製作している。この電源装置は、たとえば区画壁３をプラスチックで成形し、冷却用放熱フィン７を熱伝導に優れたアルミニウム等の金属で製作して、電池１の熱を効率よく冷却室５に伝導しながら、隣接する電池１を絶縁状態に配置できる。   In the power supply device described above, the partition wall 3 and the cooling radiating fins 7 are manufactured as separate parts. In this power supply device, for example, the partition wall 3 is formed of plastic, the cooling fins 7 are made of a metal such as aluminum having excellent heat conduction, and the heat of the battery 1 is efficiently conducted to the cooling chamber 5. Adjacent batteries 1 can be placed in an insulated state.

ただ、区画壁と冷却用放熱フィンとは、アルミニウム等の金属で一体構造とすることができる。この構造は、電池と区画壁の上面との間に絶縁シートを設ける。絶縁シートは、熱伝導の優れた接着剤を介して区画壁と電池の底面とに接着される。この構造は、絶縁シートを介して電池が区画壁の上面に絶縁状態で固定される。区画壁と冷却用放熱フィンとを一体構造とするケースは、電池室を理想的な状態で密閉構造としながら、電池の熱を冷却室に効率よく伝導できる。また、隣接する電池が、区画壁で熱結合されるので、電池の温度むらを少なくすることもできる。   However, the partition wall and the cooling heat radiating fin can be made into an integral structure with a metal such as aluminum. In this structure, an insulating sheet is provided between the battery and the upper surface of the partition wall. The insulating sheet is bonded to the partition wall and the bottom surface of the battery via an adhesive having excellent heat conduction. In this structure, the battery is fixed to the upper surface of the partition wall in an insulated state via an insulating sheet. The case in which the partition wall and the cooling heat dissipating fins are integrated with each other can efficiently conduct the heat of the battery to the cooling chamber while the battery chamber has an ideally sealed structure. Moreover, since adjacent batteries are thermally coupled at the partition wall, the temperature unevenness of the batteries can be reduced.

冷却室５は、冷却媒体で冷却されて、電池室４に配置している電池１を冷却する。図１の電源装置は、電池１に連結している冷却用放熱フィン７を冷却室５に表出し、この冷却用放熱フィン７を冷却室５の冷却媒体で冷却して、電池１を効率よく冷却する。図１の装置は、冷却室５に冷却媒体として、冷却用の空気をファン９で強制送風する。また、冷却室に絶縁油を充填し、この絶縁油で冷却用放熱フィンを冷却して、電池を冷却することもできる。空気や絶縁油を介して冷却室５の冷却用放熱フィン７を冷却する電源装置は、電池１を絶縁シート８を介することなく、プラスチック等の絶縁材の区画壁３に固定している金属製の冷却用放熱フィン７に固定できる。冷却室５で冷却用放熱フィン７を絶縁状態で冷却できるからである。   The cooling chamber 5 is cooled by the cooling medium and cools the battery 1 disposed in the battery chamber 4. The power supply device of FIG. 1 exposes the cooling radiating fins 7 connected to the battery 1 to the cooling chamber 5, and cools the cooling radiating fins 7 with the cooling medium in the cooling chamber 5, so that the battery 1 can be efficiently used. Cooling. The apparatus shown in FIG. 1 forcibly blows cooling air into the cooling chamber 5 as a cooling medium using a fan 9. Alternatively, the battery can be cooled by filling the cooling chamber with insulating oil, and cooling the cooling fins with this insulating oil. The power supply device that cools the cooling fins 7 of the cooling chamber 5 through air or insulating oil is made of metal that fixes the battery 1 to the partition wall 3 of an insulating material such as plastic without using the insulating sheet 8. It can fix to the cooling fin 7 for cooling. This is because the cooling fins 7 can be cooled in an insulated state in the cooling chamber 5.

また、冷却媒体として冷却液を使用し、冷却液を冷却室５に循環させて電池１を冷却することもできる。この電源装置は、冷却液で冷却用放熱フィン７を冷却して電池１を冷却する。冷却媒体を冷却液とする電源装置は、電池１に冷却用放熱フィン７を連結することなく、図３に示すように、冷却液で区画壁３の下面を冷却し、区画壁３で電池１を冷却することができる。冷却液が効率よく区画壁３を冷却できるからである。また、冷却室５に、区画壁３の下面に接するように冷却液循環パイプ１０を配設し、この冷却液循環パイプ１０で区画壁３を下面から冷却し、区画壁３の上面に固定している電池１を冷却することもできる。冷却液循環パイプ１０は、冷却液の冷却循環装置１１に連結されて、冷却液が循環される。   Further, the battery 1 can be cooled by using a cooling liquid as a cooling medium and circulating the cooling liquid to the cooling chamber 5. This power supply apparatus cools the battery 1 by cooling the cooling fins 7 with the coolant. As shown in FIG. 3, the power supply apparatus using the cooling medium as the cooling liquid cools the lower surface of the partition wall 3 with the coolant without connecting the cooling fins 7 to the battery 1. Can be cooled. This is because the cooling liquid can cool the partition wall 3 efficiently. Further, a coolant circulation pipe 10 is disposed in the cooling chamber 5 so as to contact the lower surface of the partition wall 3, and the partition wall 3 is cooled from the lower surface by the coolant circulation pipe 10 and fixed to the upper surface of the partition wall 3. The battery 1 can be cooled. The coolant circulation pipe 10 is connected to a coolant circulation device 11 for circulating coolant so that the coolant is circulated.

図４ないし図８に示す電源装置は、複数の電池１を、上端を接続端子１５とする垂直姿勢で直径方向に並べて、上端部をケース２に収納している。ケース２は、プラスチック等の絶縁材で成形されて、下方を開口する独立閉鎖室１２を設けている。独立閉鎖室１２は、各々の電池１の上部を挿入するように、電池１の個数と同じ数を設けている。図の電池１は円筒型電池１であるから、独立閉鎖室１２の下方の開口部は円形としている。電池を角型電池とする電源装置は、独立閉鎖室の開口部を角形とする。   In the power supply device shown in FIGS. 4 to 8, a plurality of batteries 1 are arranged in the diameter direction in a vertical posture with the upper ends as connection terminals 15, and the upper ends are housed in the case 2. The case 2 is formed of an insulating material such as plastic and is provided with an independent closed chamber 12 that opens downward. The number of independent closed chambers 12 is the same as the number of batteries 1 so that the upper part of each battery 1 is inserted. Since the battery 1 in the figure is a cylindrical battery 1, the opening below the independent closed chamber 12 is circular. In a power supply device using a square battery as a battery, the opening of the independent closed chamber is square.

ケース２は、独立閉鎖室１２の天板２ａに、ガスの放出弁に併用されるグロメット１３を設けている。さらに、グロメット１３は、電池１の接続端子１５に接続している電圧検出用のリード線１４や電池１の温度を検出する温度センサーに接続しているリード線を密閉状態で挿通させている。グロメット１３は外周溝１３Ａを有する。外周溝１３Ａには、天板２ａに設けた貫通孔２ｂの内周縁を密着状態で入れて、グロメット１３で貫通孔２ｂを密閉状態に閉塞している。グロメット１３は、電池１の上端部に設けた安全弁（図示せず）が開弁して、独立閉鎖室１２の圧力が高くなると、天板２ａの貫通孔２ｂから外れ、あるいはずれて、電池１から排出されるガスを独立閉鎖室１２の外部に排出させる排気弁２８に併用される。   In the case 2, a grommet 13 that is used in combination with a gas release valve is provided on the top plate 2 a of the independent closed chamber 12. Further, the grommet 13 has a lead wire 14 for voltage detection connected to the connection terminal 15 of the battery 1 and a lead wire connected to a temperature sensor for detecting the temperature of the battery 1 inserted in a sealed state. The grommet 13 has an outer peripheral groove 13A. The inner peripheral edge of the through hole 2b provided in the top plate 2a is put in close contact with the outer peripheral groove 13A, and the through hole 2b is closed in a sealed state with the grommet 13. When the safety valve (not shown) provided at the upper end of the battery 1 is opened and the pressure in the independent closed chamber 12 is increased, the grommet 13 is disengaged or displaced from the through hole 2b of the top plate 2a. It is used together with the exhaust valve 28 for exhausting the gas discharged from the outside to the outside of the independent closed chamber 12.

電池１は、上部をケース２の独立閉鎖室１２に挿入している。独立閉鎖室１２は、挿入されるを電池１で開口部を閉塞して、密閉構造となる。独立閉鎖室１２の開口部は、内形を円筒型電池１の外形にほぼ等しくして、電池１で開口部を閉塞できるようにしている。電池１は、独立閉鎖室１２に上部を挿入して、上部に設けている接続端子部１Ａを独立閉鎖室１２に配設する。   The upper part of the battery 1 is inserted into the independent closed chamber 12 of the case 2. The independent closed chamber 12 is inserted to close the opening with the battery 1 and has a sealed structure. The opening of the independent closed chamber 12 has an inner shape substantially equal to the outer shape of the cylindrical battery 1 so that the battery 1 can close the opening. In the battery 1, the upper portion is inserted into the independent closed chamber 12, and the connection terminal portion 1 </ b> A provided at the upper portion is disposed in the independent closed chamber 12.

図の電源装置は、隣接する電池１をバスバー２０で直列に接続している。電池１は、バスバー２０を連結する接続端子１５を封口板１６に設けている。さらに、図の電源装置は、隣接する電池１を絶縁するために、電池１を絶縁カバー１７で被覆している。互いに直列に接続される電池１は、隣接する電池１の外装缶１８との間に電位差ができる。また、図に示すように、電池１を複数列に配列すると、各列間の電池１の外装缶１８に大きな電位差ができる。このため、電池１の外装缶１８は、互いに絶縁して配置する必要がある。図７の電池１は、上端部を円筒状の絶縁カバー１７で絶縁している。絶縁カバー１７は、電池１の端部を挿入できるキャップ状にプラスチック等の絶縁材を成形したもの、あるいは、電池１の端部を挿入するプラスチックチューブ、あるいは電池１の端部を挿入して収縮させる熱収縮チューブ等である。   In the illustrated power supply apparatus, adjacent batteries 1 are connected in series by a bus bar 20. In the battery 1, connection terminals 15 that connect the bus bars 20 are provided on the sealing plate 16. Further, in the illustrated power supply apparatus, the battery 1 is covered with an insulating cover 17 in order to insulate the adjacent batteries 1. The batteries 1 connected in series with each other have a potential difference between the adjacent cans 18 of the batteries 1. Further, as shown in the figure, when the batteries 1 are arranged in a plurality of rows, a large potential difference is generated in the outer can 18 of the battery 1 between the rows. For this reason, the outer can 18 of the battery 1 needs to be insulated from each other. In the battery 1 of FIG. 7, the upper end portion is insulated by a cylindrical insulating cover 17. The insulating cover 17 is formed by molding an insulating material such as plastic into a cap shape into which the end of the battery 1 can be inserted, or a plastic tube into which the end of the battery 1 is inserted, or the end of the battery 1 is inserted to contract. A heat shrinkable tube or the like.

電池１を直列に接続するバスバー２０は、金属板を全体の形状がＬ字状となるように折曲加工したものである。Ｌ字状のバスバー２０は、一端を接続端子１５に、他端を外装缶１８に接続して、電池１を直列に接続する。図７のバスバー２０は、電池１の上端部の接続端子１５に接続される上端連結部２１と、この上端連結部２１を連結している電池１に隣接して配置される電池１の外装缶１８に接続される外装缶連結部２２とからなる。バスバー２０は、上端連結部２１と外装缶連結部２２を互いに直交するように連結する形状として、全体をＬ字状としている。   The bus bar 20 for connecting the batteries 1 in series is obtained by bending a metal plate so that the entire shape is L-shaped. The L-shaped bus bar 20 has one end connected to the connection terminal 15 and the other end connected to the outer can 18 to connect the batteries 1 in series. The bus bar 20 in FIG. 7 includes an upper end connecting portion 21 connected to the connection terminal 15 at the upper end portion of the battery 1 and an outer can of the battery 1 disposed adjacent to the battery 1 connecting the upper end connecting portion 21. 18 and an outer can connecting portion 22 connected to 18. The bus bar 20 has an L shape as a whole so that the upper end connecting portion 21 and the outer can connecting portion 22 are connected so as to be orthogonal to each other.

バスバー２０の外装缶連結部２２は、２分岐された分岐アーム２２Ａである。分岐アーム２２Ａは、隣接する円筒型電池１の谷間に配置されて、隣接する電池１の間に挟着される位置に配置されない。この構造は、電池１の間に、分岐アーム２２Ａを配置する隙間を設ける必要がない。隣接する電池１を互いに接近して配置してできる谷間のスペースに分岐アーム２２Ａを配置するからである。   The outer can connecting portion 22 of the bus bar 20 is a bifurcated branch arm 22A. The branch arm 22 </ b> A is disposed between the valleys of the adjacent cylindrical batteries 1, and is not disposed at a position sandwiched between the adjacent batteries 1. In this structure, there is no need to provide a gap for arranging the branch arm 22 </ b> A between the batteries 1. This is because the branch arm 22A is arranged in a space formed by arranging adjacent batteries 1 close to each other.

さらに、図７のバスバー２０は、２本の分岐アーム２２Ａの上端をＬ字状に折曲して、折曲端を上端連結部２１に連結する形状としている。このバスバー２０は、弾性変形できる金属板で製作して、耐振性を向上できる。バスバー２０が弾性変形して振動を吸収するからである。弾性変形できるバスバー２０は、たとえば、鉄や鉄合金の表面を、銅、ニッケル、クローム等のメッキをした金属板を使用する。ただし、バスバーには、銅や銅合金を使用し、さらにその表面をメッキして、電気抵抗を小さくすることもできる。   Furthermore, the bus bar 20 of FIG. 7 is configured such that the upper ends of the two branch arms 22A are bent in an L shape and the bent ends are connected to the upper end connecting portion 21. The bus bar 20 can be made of a metal plate that can be elastically deformed to improve vibration resistance. This is because the bus bar 20 is elastically deformed and absorbs vibration. As the bus bar 20 that can be elastically deformed, for example, a metal plate in which the surface of iron or an iron alloy is plated with copper, nickel, chrome, or the like is used. However, the bus bar can be made of copper or a copper alloy, and the surface thereof can be further plated to reduce the electric resistance.

バスバー２０は、抵抗溶接であるスポット溶接で外装缶１８に連結される。図７のバスバー２０は、上端連結部２１の下端部に、外装缶１８の表面に抵抗溶接する接続片２３を設けている。接続片２３は、所定の幅と長さを有し、かつ外装缶１８の表面に沿う形状に湾曲されている。この接続片２３は、分岐アーム２２Ａの内側からＶ字状に折曲されて、外装缶１８の表面に沿うようにしている。このバスバー２０は、接続片２３をスポット溶接して、外装缶１８に接続される。   The bus bar 20 is connected to the outer can 18 by spot welding which is resistance welding. In the bus bar 20 of FIG. 7, a connection piece 23 that is resistance-welded to the surface of the outer can 18 is provided at the lower end portion of the upper end connecting portion 21. The connection piece 23 has a predetermined width and length and is curved into a shape along the surface of the outer can 18. The connecting piece 23 is bent in a V shape from the inside of the branch arm 22 </ b> A so as to be along the surface of the outer can 18. The bus bar 20 is connected to the outer can 18 by spot welding the connection piece 23.

上端連結部２１は、電池１の封口板１６に設けている接続端子１５に連結される。図の上端連結部２１は、接続端子１５のボルト１５Ａの貫通孔２１Ａを設けている。この上端連結部１２は、貫通孔２１Ａにボルト１５Ａを挿通し、ボルトにナット１９を締め付けて、接続端子１５に接続される。この構造は、図７に示すように、分岐アーム２２Ａを電池１に連結し、この電池１を、上端連結部２１の貫通孔２１Ａにボルト１５Ａを挿通して並べ、ボルト１５Ａにナット１９を締め付けて、電池１を特定の配列に固定できる。バスバー２０の一端をボルトとナット１９で電池１に連結している電源装置は、ナット１９を外して電池１を分離できる。このため、メンテナンスのときに、特定の電池１を交換できる。また、簡単に能率よく組み立てできる特徴もある。ただ、バスバーの上端連結部は、抵抗溶接やレーザー溶接等の方法で溶着して封口板に連結することができる。上端連結部が溶着される電池は、接続端子を設けることなく、封口板に直接に溶着することもできる。   The upper end connecting portion 21 is connected to the connection terminal 15 provided on the sealing plate 16 of the battery 1. The upper end connecting portion 21 in the figure is provided with a through hole 21 </ b> A of the bolt 15 </ b> A of the connection terminal 15. The upper end connecting portion 12 is connected to the connection terminal 15 by inserting a bolt 15 </ b> A through the through-hole 21 </ b> A and fastening a nut 19 to the bolt. As shown in FIG. 7, this structure connects the branch arm 22A to the battery 1, arranges the battery 1 by inserting the bolt 15A through the through hole 21A of the upper end connecting portion 21, and tightens the nut 19 to the bolt 15A. Thus, the battery 1 can be fixed in a specific arrangement. The power supply device in which one end of the bus bar 20 is connected to the battery 1 with a bolt and a nut 19 can remove the nut 19 to separate the battery 1. For this reason, the specific battery 1 can be replaced at the time of maintenance. There is also a feature that allows easy and efficient assembly. However, the upper end connecting portion of the bus bar can be welded and connected to the sealing plate by a method such as resistance welding or laser welding. The battery to which the upper end connecting portion is welded can be directly welded to the sealing plate without providing the connection terminal.

バスバー２０で連結された電池１が、ケース２の独立閉鎖室１２に挿入される。図７に示すケース２は、各列の電池１間に配設される中間ケース２Ｂと、この中間ケース２Ｂの両側に連結される一対の側面ケース２Ａとに分割している。この構造のケース２は、中間ケース２Ｂの両側に電池１を配列する状態で、中間ケース２Ｂの両側に側面ケース２Ａを連結して、電池１の上端を独立閉鎖室１２に挿入する状態とする。中間ケース２Ｂの両側に側面ケース２Ａを連結する状態で、各々の電池１の上部を挿入する独立閉鎖室１２を形成するように、中間ケース２Ｂと側面ケース２Ａの内面には、仕切壁２４を一体的に成形して設けている。仕切壁２４は、ケース２の内部に、下方を開口している独立閉鎖室１２を区画して設ける形状に成形している。さらに、仕切壁２４で成形される独立閉鎖室１２に、電池１の上端を挿入して、独立閉鎖室１２の下端開口部を電池１で閉塞して、独立閉鎖室１２を密閉構造とするようにしている。したがって、仕切壁２４は、下端縁を電池１の外周面に密着し、あるいは電池に被着している絶縁シートに密着する形状としている。   The battery 1 connected by the bus bar 20 is inserted into the independent closed chamber 12 of the case 2. The case 2 shown in FIG. 7 is divided into an intermediate case 2B disposed between the batteries 1 in each row, and a pair of side surface cases 2A connected to both sides of the intermediate case 2B. In the case 2 having this structure, the battery 1 is arranged on both sides of the intermediate case 2B, the side case 2A is connected to both sides of the intermediate case 2B, and the upper end of the battery 1 is inserted into the independent closed chamber 12. . In a state where the side case 2A is connected to both sides of the intermediate case 2B, a partition wall 24 is formed on the inner surface of the intermediate case 2B and the side case 2A so as to form an independent closed chamber 12 into which the upper part of each battery 1 is inserted. It is formed integrally. The partition wall 24 is formed in a shape in which the independent closed chamber 12 that opens downward is partitioned and provided inside the case 2. Further, the upper end of the battery 1 is inserted into the independent closed chamber 12 formed by the partition wall 24, and the lower end opening of the independent closed chamber 12 is closed by the battery 1, so that the independent closed chamber 12 has a sealed structure. I have to. Accordingly, the partition wall 24 has a shape in which the lower end edge is in close contact with the outer peripheral surface of the battery 1 or in close contact with the insulating sheet attached to the battery.

上部を独立閉鎖室１２に挿入する電池１は、下部を独立閉鎖室１２の外部に配置する。独立閉鎖室１２の外部に配置される電池１の下部が冷却される。図８の電源装置は、框体２５にケース２と電池１を配置して、電池１の下部を強制冷却する。この図の電源装置は、框体２５とケース２との間に排気ダクト２６と吸気ダクト２７を設けている。吸気ダクト２７は電池１の下方に設けている。排気ダクト２６は電池１の側方と上方に設けている。吸気ダクト２７は冷却空気の送風器（図示せず）に連結される。送風器が吸気ダクト２７に供給する冷却空気は、電池１の間の隙間に強制送風されて、電池１を冷却する。電池１の隙間を通過した空気は、電池１の側方に設けている排気ダクト２６を通過し、さらに、電池１の上方に設けている排気ダクト２６を通過して框体２５の外部に排気される。   The battery 1 in which the upper part is inserted into the independent closed chamber 12 is arranged with the lower part outside the independent closed chamber 12. The lower part of the battery 1 arranged outside the independent closed chamber 12 is cooled. In the power supply device of FIG. 8, the case 2 and the battery 1 are disposed in the housing 25 and the lower part of the battery 1 is forcibly cooled. In the power supply device of this figure, an exhaust duct 26 and an intake duct 27 are provided between the housing 25 and the case 2. The intake duct 27 is provided below the battery 1. The exhaust duct 26 is provided on the side and upper side of the battery 1. The intake duct 27 is connected to a cooling air blower (not shown). Cooling air supplied to the intake duct 27 by the blower is forcedly blown into the gap between the batteries 1 to cool the battery 1. The air that has passed through the gap of the battery 1 passes through the exhaust duct 26 provided on the side of the battery 1, passes through the exhaust duct 26 provided above the battery 1, and exhausts to the outside of the housing 25. Is done.

この電源装置は、框体２５でもって、ケース２の天板２ａの上方に、ケース２の独立閉鎖室１２に隣接して、冷却空気の排気ダクト２６を設けている。独立閉鎖室１２と排気ダクト２６の間の天板２ａは、排気弁２８に併用されるグロメット１３を設けている。この構造の電源装置は、電池１の安全弁が開弁すると、電池１から独立閉鎖室１２にガスが排出される。この状態になると、独立閉鎖室１２の圧力が高くなって、排気弁２８が開弁する。排気弁２８に併用されるグロメット１３は、天板２ａの貫通孔２ｂから外れ、あるいはずれてガスを通過させる状態となる。この状態になると、独立閉鎖室１２からガスが排気ダクト２６に排出される。排気ダクト２６は、電池１を冷却する空気を強制送風しているので、独立閉鎖室１２から排出されるガスは、冷却空気で強制的に框体２５の外部に吹き出される。このため、電池１から排出されるガスをスムーズに框体２５の外部に排気できる。   This power supply device is provided with a cooling air exhaust duct 26 adjacent to the independent closed chamber 12 of the case 2 above the top plate 2 a of the case 2 with the casing 25. The top plate 2 a between the independent closed chamber 12 and the exhaust duct 26 is provided with a grommet 13 that is used together with the exhaust valve 28. In the power supply device having this structure, when the safety valve of the battery 1 is opened, gas is discharged from the battery 1 to the independent closed chamber 12. If it will be in this state, the pressure of the independent closed chamber 12 will become high, and the exhaust valve 28 will open. The grommet 13 used in combination with the exhaust valve 28 is in a state in which the gas passes through the through hole 2b of the top plate 2a or is displaced or displaced. In this state, gas is discharged from the independent closed chamber 12 to the exhaust duct 26. Since the exhaust duct 26 forcibly blows air for cooling the battery 1, the gas discharged from the independent closed chamber 12 is forcibly blown out of the housing 25 by the cooling air. For this reason, the gas discharged from the battery 1 can be smoothly exhausted to the outside of the housing 25.
