DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An example of the present disclosure will be described below with reference to the accompanying drawings. In the following description, terms indicating specific directions or positions (e.g., terms including "upper", "lower", "right" and "left") are used as necessary, but the use of these terms is for the purpose of facilitating understanding of the present disclosure with reference to the drawings, and the meanings of these terms do not limit the technical scope of the present disclosure. In addition, the following description is essentially merely illustrative, and is not intended to limit the present disclosure, its application, or its uses. Furthermore, the drawings are schematic, and the ratios of the dimensions do not necessarily correspond to the real ones.

[0013] As shown in Fig. 1, a storage battery unit 1 according to an embodiment of the present disclosure includes a plurality of storage battery modules 2 as an example of a plurality of units, and a control unit 3 connected to each of the plurality of storage battery modules 2. In this embodiment, the storage battery unit 1 further includes a base 4 for integrally fixing each of the storage battery modules 2 to an installation location. As shown in Fig. 2, each of the plurality of storage battery modules 2, the control unit 3, and the base 4 constituting the storage battery unit 1 is configured to be separable independently of one another.

[0014] As shown in Fig. 1, for example, each storage battery module 2 has a storage battery 10 and a storage battery unit housing 20 in which the storage battery 10 is accommodated, and the storage battery modules 2 are integrated and separable from each other. As shown in Fig. 3, the storage battery 10 is composed of a plurality of cells. Each storage battery unit housing 20 has a substantially rectangular parallelepiped shape and has a substantially rectangular mounting surface 21 on which the control unit 3 is mounted.

[0015] 3, the mounting surface 21 has a first connecting portion 22, a first positioning recess 23, and a second positioning recess 24. In this embodiment, two first connecting portions 22, two first positioning recesses 23, and two second positioning recesses 24 are provided, and are disposed substantially symmetrically with respect to a center P1 of the mounting surface 21 in the longitudinal direction.

[0016] Each of the first connecting portions 22 is disposed at both ends in the longitudinal direction of the mounting surface 21. Each of the first positioning recesses 23 is configured to be able to accommodate a first positioning protrusion 43 described later, and is disposed closer to the center P1 of the mounting surface 21 in the longitudinal direction of the mounting surface 21 than the first connecting portions 22. Each of the second positioning recesses 24 is configured to be able to accommodate a second positioning protrusion 44 described later, and is disposed farther from the center P1 of the mounting surface 21 in the longitudinal direction of the mounting surface 21 than the first connecting portions 22.

[0017] 1, the control unit 3 has, as an example, a control device 30 that controls the storage batteries 10 of each storage battery module 2, and a control unit housing 40 that accommodates the control device 30. As shown in FIG. 4, the control unit housing 40 has a substantially rectangular parallelepiped shape and has a mounting surface 41 that is attached to the mounting surface 21 of each of the multiple storage battery modules 2.

[0018] 4, the mounting surface 41 has a second connecting portion 42, a first positioning protrusion 43, and a second positioning protrusion 44. In this embodiment, four second connecting portions 42, four first positioning protrusions 43, and four second positioning protrusions 44 are provided, and are disposed substantially symmetrically with respect to an intersection P2 of a center line L1 extending in the longitudinal direction of the mounting surface 41 and a center line L2 extending in the lateral direction of the mounting surface 41.

[0019] Each second connection portion 42 is configured to be connectable to the first connection portion 22 of the storage battery module 2. Two second connection portions 42 are disposed on each end of the mounting surface 41 in the longitudinal direction thereof, and are disposed so as to face the first connection portions 22 when the control unit 3 is attached to the storage battery module 2.

[0020] 5, each second connection portion 42 is configured to be able to be pulled out from the mounting surface 41. More specifically, each second connection portion 42 is configured with a connector 421 connectable to the first connection portion 22, and a wire harness 422 connected to the connector 421. That is, the first connection portion 22 and each of the multiple second connection portions 42 are connected by connector fitting. The wire harness 422 is accommodated inside the control unit housing 40, and enables the connector 421 to be pulled out from the mounting surface 41.

[0021] Each of the first positioning protrusions 43 and the second positioning protrusions 44 extends in a direction perpendicular to the mounting surface 41 and away from the mounting surface 41. In other words, each of the first positioning protrusions 43 and the second positioning protrusions 44 is configured to extend from the mounting surface 41 toward the mounting surface 21 of the storage battery module 2 in a state in which the control unit 3 is mounted on the storage battery module 2. Each of the first positioning protrusions 43 is disposed closer to the intersection P2 of the mounting surface 41 than the second connection portion 42 in the longitudinal direction of the mounting surface 41. Each of the second positioning protrusions 44 is disposed farther from the intersection P2 of the mounting surface 41 than the second connection portion 42 in the longitudinal direction of the mounting surface 41. In other words, each of the positioning protrusions 44 is provided on the outer side of the first positioning protrusions 43 of the mounting surface 41.

[0022] Each of the first positioning projections 43 is configured so that the area in a plan view seen from a direction perpendicular to the mounting surface 41 is larger than that of the second positioning projection 44. As an example, each of the first positioning projections 43 has a substantially rectangular shape in a plan view seen from a direction perpendicular to the mounting surface 41, and each of the second positioning projections 44 has a substantially cylindrical shape. Also, as shown in FIG. 5, each of the first positioning projections 43 has a tapered shape that tapers away from the mounting surface 41. In detail, each of the first positioning projections 43 has a substantially truncated pyramid shape and is composed of a tip surface 45 that is substantially parallel to the mounting surface 41, and an inclined surface 46 connected to the mounting surface 41 and the tip surface 45. In other words, if a straight line that passes through the center of the tip surface 45 and extends in a direction perpendicular to the mounting surface 41 is defined as a straight line L3, the inclined surface 46 is inclined away from the straight line L3 as it moves from the tip surface 45 to the mounting surface 41 along the straight line L3.

[0023] The storage battery unit 1 can provide the following effects.

[0024] The storage battery unit 1 is composed of a plurality of separable units. More specifically, the storage battery unit 1 includes a plurality of storage battery modules 2 each housing a storage battery 10 and integrally configured to be separable from one another, and a control unit 3 connected to each of the plurality of storage battery modules 2 and controlling the storage batteries 10. With this configuration, the plurality of units, for example the plurality of storage battery modules 2 and the control unit 3, can be separated for transportation, thereby realizing an easily transportable storage battery unit 1.

[0025] The mounting surface 21 of each storage battery module 2 has a first connection portion 22, and the mounting surface 41 of the control unit 3 has a plurality of second connection portions 42 that can be respectively connected to the first connection portions 22 of each of the plurality of storage battery modules 2. The first connection portion 22 and each of the plurality of second connection portions 42 are connected by connector fitting. Also, each of the plurality of second connection 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, a storage battery unit 1 that is easy to transport and easy to assemble can be realized. In addition, in order to reduce the weight of the storage battery unit during transportation, it is also possible to transport the housing and the storage battery module separately in the storage battery unit of Patent Document 1. In this case, the storage battery module is usually stored in the housing after the housing is installed at the installation location, but there may be a problem that it takes time to install wiring, etc. In the storage battery unit 1 of the present disclosure, the control unit 23 and each of the multiple storage battery modules 2 are connected by the first connection portion 22 and the second connection portion 42, thereby reducing the amount of wiring and avoiding such problems.

[0026] The mounting surface 41 of the control unit 3 has a first positioning protrusion 43 extending from the mounting surface 41 toward the mounting surface 21, and the mounting surface 21 of each storage battery module 2 has a first positioning recess 23 that receives the first positioning protrusion 43 when the mounting surface 41 is attached to the mounting surface 21. With this configuration, it is possible to position the storage battery module 2 and the control unit 3. As a result, it is possible to realize a storage battery unit 1 that is easy to transport and assemble.

[0027] The mounting surface 41 of the control unit 3 has a second positioning protrusion 44 that is provided outside the first positioning protrusion 43 of the mounting surface 41 and extends from the mounting surface 41 toward the mounting surface 21, and the mounting surface 21 of each storage battery module 2 has a second positioning recess 24 that receives the second positioning protrusion 44 when the mounting surface 41 is attached to the mounting surface 21. This configuration makes it possible to more accurately position the storage battery module 2 and the control unit 3. As a result, a storage battery unit 1 that is easy to transport and assemble can be realized.

[0028] The first positioning protrusion 43 has a larger area in a plan view seen from a direction perpendicular to the mounting surface 41 than the second positioning protrusion 44. With this configuration, the storage battery module 2 and the control unit 3 can be roughly positioned by the first positioning protrusion 43 and the first positioning recess 23, and then the storage battery module 2 and the control unit 3 can be more precisely positioned by the second positioning protrusion 44 and the second positioning recess 24. As a result, a storage battery unit 1 that is easy to transport and assemble can be realized.

[0029] The first positioning protrusion 43 has a tapered shape that tapers away from the mounting surface 41. This configuration makes it easy to accommodate the first positioning protrusion 43 in the first positioning recess 23. As a result, it is possible to realize a storage battery unit 1 that is easy to transport and assemble.

[0030] The storage battery unit 1 can also be configured as follows.

[0031] The storage battery unit 1 of the present disclosure is not limited to the above embodiment, and may have any configuration including a plurality of storage battery modules each containing a storage battery and integrated so as to be separable from one another, and a control unit connected to each of the plurality of storage battery modules to control the storage batteries. For example, any one, any two or all of the first connecting portion 22, the second connecting portion 42, the first positioning protrusion 43, the first positioning recess 23, the second positioning protrusion 44 and the second positioning recess 24 may be omitted.

[0032] The first positioning protrusion 43 may be provided on the mounting surface 21 of the storage battery module 2, and the first positioning recess 23 may be provided on the mounting surface 41 of the control unit 3. Similarly, the second positioning protrusion 44 may be provided on the mounting surface 21 of the storage battery module 2, and the second positioning recess 24 may be provided on the mounting surface 41 of the control unit 3. Furthermore, the first positioning protrusion 43 and the second positioning recess 24 may be provided on the mounting surface 21 of the storage battery module 2, and the second positioning protrusion 44 and the first positioning recess 23 may be provided on the mounting surface 41 of the control unit 3, or conversely, the first positioning protrusion 43 and the second positioning recess 24 may be provided on the mounting surface 41 of the control unit 3, and the second positioning protrusion 44 and the first positioning recess 23 may be provided on the mounting surface 41 of the storage battery module 2.

[0033] The area of ​​the first positioning protrusion 43 in a plan view from a direction perpendicular to the mounting surface 41 is not limited to being larger than that of the second positioning protrusion 44, and may be the same as or smaller than that of the second positioning protrusion 44. The first positioning protrusion 43 is not limited to being substantially pyramidal, and may be configured in any shape. Similarly, the second positioning protrusion 44 is not limited to being substantially cylindrical, and may be configured in any shape.

[0034] As shown in Fig. 6 and Fig. 7, the storage battery unit 1 can constitute a part of a storage battery device 100. The storage battery device 100 in Fig. 6 includes the storage battery unit 1 and a wall-hanging stand 50 that is attached to the storage battery unit 1 and enables the storage battery unit 1 to be hung on a wall 110 without touching the floor. The storage battery device 100 in Fig. 7 also includes the storage battery unit 1 and a fixing bracket 60 that is attached to the storage battery unit 1 and enables the storage battery unit 1 to be fixed to the wall 110 in a state in which it is installed on the floor 120. With this configuration, the storage battery unit 1 can be used to realize a storage battery device 100 that is easy to transport and easy to install on a wall or floor.

[0035] 6, the stand 50 is composed of a plate-shaped main body 51 attached to the wall 110, and a flange 52 provided at the lower vertical end of the main body 51 and to which the base 4 of the storage battery unit 1 is attached. The stand 50 does not have any braces or beam members connected to the main body 51 and the flange 52 to reinforce the stand. This makes it easy to install and maintain the storage battery device 100 without compromising its appearance.

[0036] As shown in FIG. 8, the fixing bracket 60 is disposed between the control unit 3 and the wall 110, and is composed of an L-shaped bracket 61, a wall fixing plate 62, and a cover plate 63. The L-shaped bracket 61 is attached to the control unit 3 of the storage battery unit 1. The wall fixing plate 62 is fixed to the wall 110, and the L-shaped bracket 61 is attached to it. The wall fixing plate 62 allows the storage battery unit 1 to be repeatedly attached to and detached from the wall 110. As a result, the maintenance of the storage battery unit 1 after installation can be improved. The cover plate 63 closes the gap between the storage battery unit 1 and the wall 110 when the storage battery unit 1 is installed. The cover plate 63 can prevent the fixing bracket 60 from impairing the appearance of the storage battery device 100.
