Specifically, each second connection portion 42 is composed of a connector 421 that can be connected to the first connection portion 22, and a wire harness 422 that is connected to the connector 421. That is, each of the first connection portion 22 and the plurality of second connection portions 42 is connected by connector fitting. The wire harness 422 is housed inside the control unit housing 40 and allows the connector 421 to be pulled out from the mounting surface 41.

第１位置決め突起４３および第２位置決め突起４４の各々は、取付面４１に直交する方向に沿って取付面４１から離れる方向に延びている。言い換えると、第１位置決め突起４３および第２位置決め突起４４の各々は、蓄電池モジュール２に制御ユニット３を取り付けた状態で取付面４１から蓄電池モジュール２の被取付面２１に向かって延びるように構成されている。各第１位置決め突起４３は、取付面４１の長手方向において、第２接続部４２よりも取付面４１の交点Ｐ２の近くに配置されている。各第２位置決め突起４４は、取付面４１の長手方向において、第２接続部４２よりも取付面４１の交点Ｐ２から離れて配置されている。つまり、各位置決め突起４４は、取付面４１の第１位置決め突起４３よりも外側に設けられている。 Each of the first positioning protrusion 43 and the second positioning protrusion 44 extends in a direction away from the mounting surface 41 along a direction orthogonal to the mounting surface 41.

Each of the first positioning protrusions 43 is arranged closer to the intersection P2 of the mounting surface 41 than the second connecting portion 42 in the longitudinal direction of the mounting surface 41. Each of the second positioning protrusions 44 is arranged in the longitudinal direction of the mounting surface 41 at a distance from the intersection P2 of the mounting surface 41 with respect to the second connecting portion 42. That is, each positioning protrusion 44 is provided outside the first positioning protrusion 43 of the mounting surface 41.

各第１位置決め突起４３は、取付面４１に直交する方向から見た平面視における面積が第２位置決め突起４４よりも大きくなるように構成されている。一例として、各第１位置決め突起４３は、取付面４１に直交する方向から見た平面視において略矩形状を有し、各第２位置決め突起４４は、略円柱形状を有している。また、各第１位置決め突起４３は、図５に示すように、取付面４１から離れるに従って先細りになるテーパー形状を有している。詳しくは、各第１位置決め突起４３は、略角錐台形状を有し、取付面４１に略平行な先端面４５と、取付面４１と先端面４５とに接続された傾斜面４６とで構成されている。つまり、先端面４５の中心を通り取付面４１に直交する方向に沿って延びる直線を直線Ｌ３とすると、傾斜面４６は、直線Ｌ３に沿って先端面４５から取付面４１に向かうに従って、直線Ｌ３から離れるように傾斜している。 Each of the first positioning protrusions 43 is configured so that the area in a plan view seen from a direction orthogonal to the mounting surface 41 is larger than that of the second positioning protrusion 44. As an example, each of the first positioning protrusions 43 has a substantially rectangular shape in a plan view viewed from a direction orthogonal to the mounting surface 41, and each second positioning protrusion 44 has a substantially cylindrical shape. Further, as shown in FIG. 5, each first positioning projection 43 has a tapered shape that tapers as the distance from the mounting surface 41 increases. Specifically, each of the first positioning protrusions 43 has a substantially pyramidal trapezoidal shape, and is composed of a tip surface 45 substantially parallel to the mounting surface 41 and an inclined surface 46 connected to the mounting surface 41 and the tip surface 45. ing. That is, assuming that the straight line L3 extends along the direction perpendicular to the mounting surface 41 through the center of the tip surface 45, the inclined surface 46 is the straight line L3 as it goes from the tip surface 45 to the mounting surface 41 along the straight line L3. It is tilted away from.

蓄電池ユニット１によれば、次のような効果を発揮できる。 According to the storage battery unit 1, the following effects can be exhibited.

蓄電池ユニット１が、分離可能な複数のユニットで構成されている。詳しくは、蓄電池ユニット１が、内部に蓄電池１０がそれぞれ収容され、相互に分離可能に一体化されている複数の蓄電池モジュール２と、複数の蓄電池モジュール２の各々に接続されて蓄電池１０を制御する制御ユニット３とを備える。このような構成により、複数のユニット、例えば、複数の蓄電池モジュール２および制御ユニット３を分割して運搬することができるので、運搬し易い蓄電池ユニット１を実現できる。 The storage battery unit 1 is composed of a plurality of separable units. Specifically, the storage battery unit 1 controls the storage battery 10 by being connected to each of a plurality of storage battery modules 2 in which the storage batteries 10 are housed and integrated so as to be separable from each other, and each of the plurality of storage battery modules 2. It includes a control unit 3. With such a configuration, a plurality of units, for example, a plurality of storage battery modules 2 and a control unit 3 can be divided and transported, so that the storage battery unit 1 that is easy to transport can be realized.

各蓄電池モジュール２の被取付面２１が、第１接続部２２を有し、制御ユニット３の取付面４１が、複数の蓄電池モジュール２の各々における第１接続部２２にそれぞれ接続可能な複数の第２接続部４２を有している。第１接続部２２および複数の第２接続部４２の各々がコネクタ嵌合により接続されている。また、複数の第２接続部４２の各々が、取付面４１から引き出し可能に構成されている。このような構成により、蓄電池モジュール２および制御ユニット３を容易に接続することができる。その結果、運搬し易く組み立て易い蓄電池ユニット１を実現できる。なお、運搬時における蓄電池ユニットを軽量化するため、特許文献１の蓄電池ユニットにおいて、筐体と蓄電池モジュールとを個別に運搬することも考えられる。この場合、通常、筐体を設置場所に設置した後、蓄電池モジュールが筐体に収納されるが、配線等の施工に時間を要するという問題が生じる場合がある。本開示の蓄電池ユニット１では、制御ユニット２３と複数の蓄電池モジュール２の各々とが第１接続部２２および第２接続部４２により接続されているので、配線を少なくすることができ、このような問題を回避することができる。 The mounted surface 21 of each storage battery module 2 has a first connecting portion 22, and the mounting surface 41 of the control unit 3 can be connected to the first connecting portion 22 of each of the plurality of storage battery modules 2. It has two connecting portions 42. Each of the first connecting portion 22 and the plurality of second connecting portions 42 is connected by connector fitting. Further, each of the plurality of second connecting portions 42 is configured to be able to be pulled out from the mounting surface 41. With such a configuration, the storage battery module 2 and the control unit 3 can be easily connected. As a result, the storage battery unit 1 that is easy to carry and assemble can be realized. In order to reduce the weight of the storage battery unit during transportation, it is conceivable to separately transport the housing and the storage battery module in the storage battery unit of Patent Document 1. In this case, the storage battery module is usually housed in the housing after the housing is installed at the installation location, but there may be a problem that it takes time to construct wiring and the like. In the storage battery unit 1 of the present disclosure, since the control unit 23 and each of the plurality of storage battery modules 2 are connected by the first connection portion 22 and the second connection portion 42, wiring can be reduced. You can avoid the problem.

制御ユニット３の取付面４１が、取付面４１から被取付面２１に向かって延びる第１位置決め突起４３を有し、各蓄電池モジュール２の被取付面２１が、被取付面２１に取付面４１が取り付けられた状態で第１位置決め突起４３を収容する第１位置決め凹部２３を有する。このような構成により、蓄電池モジュール２および制御ユニット３を位置決めすることができる。その結果、運搬し易く組み立て易い蓄電池ユニット１を実現できる。 The mounting surface 41 of the control unit 3 has a first positioning projection 43 extending from the mounting surface 41 toward the mounted surface 21, and the mounted surface 21 of each storage battery module 2 has a mounting surface 41 on the mounted surface 21. It has a first positioning recess 23 that accommodates the first positioning protrusion 43 in the attached state.

With such a configuration, the storage battery module 2 and the control unit 3 can be positioned more accurately. As a result, the storage battery unit 1 that is easy to carry and assemble can be realized.

第１位置決め突起４３は、取付面４１に直交する方向から見た平面視における面積が第２位置決め突起４４よりも大きい。このような構成により、第１位置決め突起４３および第１位置決め凹部２３で、蓄電池モジュール２および制御ユニット３の荒い位置決めを行った後に、第２位置決め突起４４および第２位置決め凹部２４で、蓄電池モジュール２および制御ユニット３のより細かい位置決めを行うことができる。その結果、運搬し易く組み立て易い蓄電池ユニット１を実現できる。 The area of the first positioning protrusion 43 in a plan view seen from a direction orthogonal to the mounting surface 41 is larger than that of the second positioning protrusion 44. With such a configuration, after the storage battery module 2 and the control unit 3 are roughly positioned by the first positioning protrusion 43 and the first positioning recess 23, the storage battery module 2 is formed by the second positioning protrusion 44 and the second positioning recess 24. And finer positioning of the control unit 3 can be performed. As a result, the storage battery unit 1 that is easy to carry and assemble can be realized.

第１位置決め突起４３は、取付面４１から離れるに従って先細りになるテーパー形状を有している。このような構成により、第１位置決め突起４３の第１位置決め凹部２３への収容を容易にすることができる。その結果、運搬し易く組み立て易い蓄電池ユニット１を実現できる。 The first positioning projection 43 has a tapered shape that tapers as the distance from the mounting surface 41 increases. With such a configuration, the first positioning protrusion 43 can be easily accommodated in the first positioning recess 23.
