DETAILED DESCRIPTION OF THE INVENTION

[0010] (1) A manufacturing method for an energy storage facility according to one aspect of the present invention is a manufacturing method for an energy storage facility including an electrical panel that houses at least one of an energy storage element and a power converter, and a base member that is arranged in a first direction below the electrical panel, the method including: arranging a plurality of base members in a second direction that intersects the first direction, the base members having external dimensions larger than the external dimensions of the electrical panel in the second direction; and fixing the electrical panel onto each base member, thereby fixing the plurality of electrical panels to the plurality of base members, wherein the arranging includes arranging the plurality of base members in contact with each other in the second direction, and the fixing includes fixing the plurality of electrical panels at a predetermined interval in the second direction.

[0011] According to a manufacturing method for an energy storage facility according to one aspect of the present invention, a plurality of base members, each having an outer dimension larger than that of an electrical panel in the second direction, are arranged in contact with each other in the second direction, and the plurality of electrical panels are fixed to the plurality of base members at a predetermined interval in the second direction. In this way, even if the installation surface of the electrical panels is distorted, uneven, or tilted, or the electrical panels have large dimensional errors, by installing the plurality of electrical panels at a predetermined interval, problems such as interference between the electrical panels can be prevented. This facilitates installation of the electrical panels, thereby improving the work efficiency of the electrical panel installation work. In particular, by fixing the electrical panels on base members having an outer dimension larger than that of the electrical panels in the second direction, the plurality of electrical panels can be easily installed at a predetermined interval in the second direction. By dividing the base members for fixing the plurality of electrical panels into multiple members, the size of each base member can be reduced, thereby enabling inexpensive production of the base members and facilitating transportation and installation of the base members. By arranging the plurality of base members in contact with each other in the second direction, the spacing between the plurality of electrical panels can be prevented from becoming too large. By installing multiple electrical panels at intervals, they can be installed individually, which contributes to shortening the construction period. This also improves the work efficiency of electrical panel installation work.

[0012] (2) In the manufacturing method of the storage battery equipment described in (1) above, the fixing may include fixing the two electrical panels side by side on one of the plurality of base members.

[0013] According to the manufacturing method for the energy storage equipment described in (2) above, by arranging and fixing two electrical panels on one base member, the number of base members can be reduced compared to placing a base member for each electrical panel. This reduces the assembly tolerance that occurs when arranging base members. By arranging and fixing two electrical panels on one base member, the two electrical panels can be installed in desired positions, such as by placing them with a gap between them.

[0014] (3) In the manufacturing method of the energy storage equipment described in (2) above, the fixing may involve fixing the two electrical panels side by side on the single base member so that the back faces of the two electrical panels face each other.

[0015] According to the manufacturing method for the energy storage equipment described in (3) above, two electrical panels are arranged and fixed on one base member with their backs facing each other. In other words, two rows of electrical panels can be installed side by side with their backs facing each other using one base member. This makes it possible to omit the placement of a base member when installing the second row of electrical panels.

[0016] (4) The manufacturing method of the energy storage equipment described in any one of (1) to (3) above may further include arranging any one of the plurality of base members at a distance from another base member in a third direction intersecting the first direction and the second direction.

[0017] According to the manufacturing method of the energy storage equipment described in (4) above, by arranging the base members so as to be spaced apart in the third direction, the dimensional tolerance of the base members in the third direction can be absorbed by the spaces between the base members, thereby making it possible to align the front faces of the base members lined up in the second direction.

[0018] (5) The manufacturing method for the storage equipment described in any one of (1) to (3) above may further include arranging one of the plurality of base members in contact with another base member in a third direction intersecting the first direction and the second direction.

[0019] According to the manufacturing method for the electricity storage facility described in (5) above, by arranging the base members in contact with each other in the third direction, it is possible to prevent the gap between the electrical panels in the third direction from becoming too large.

[0020] (6) In the method for manufacturing an electric storage facility according to any one of (1) to (5) above, each base member may have a frame shape in a plan view.

[0021] According to the method for manufacturing the electricity storage facility described in (6) above, the base member has a frame shape, which makes it possible to reduce the weight of the base member and the amount of material used.

[0022] (7) In the manufacturing method of the storage facility described in any one of (1) to (6) above, the fixing may include fixing the electrical panel onto each base member using a positioning portion provided on each base member.

[0023] According to the manufacturing method for the electricity storage facility described in (7) above, the electrical board can be easily fixed onto the base member by fixing the electrical board using the positioning portion of the base member.

[0024] (8) One aspect of the present invention provides a power storage facility comprising an electrical panel that houses at least one of a power storage element and a power converter, and a base member that is arranged in a first direction below the electrical panel, the power storage facility comprising a plurality of the base members that are arranged in a second direction that intersects the first direction, and a plurality of the electrical panels that are fixed to the plurality of base members, each electrical panel being fixed onto each of the base members, the base members having external dimensions in the second direction that are larger than the external dimensions of the electrical panels, the plurality of base members being arranged in contact with each other in the second direction, and the plurality of electrical panels being arranged at predetermined intervals in the second direction.

[0025] According to one aspect of the present invention, a plurality of base members, each having an outer dimension larger than that of an electrical panel in the second direction, are arranged in contact with each other in the second direction, and the plurality of electrical panels are fixed to the plurality of base members at predetermined intervals in the second direction. In this manner, even if the installation surface of the electrical panel is distorted, uneven, or tilted, or the electrical panel has a large dimensional error, the plurality of electrical panels are installed at predetermined intervals when the electrical panel is fixed to the base member, thereby preventing problems such as interference between the electrical panels. This allows the electrical panel to be easily installed, thereby improving the work efficiency of the electrical panel installation work. In particular, since the electrical panel is fixed to a base member having an outer dimension larger than that of the electrical panel in the second direction, the plurality of electrical panels can be easily installed at predetermined intervals in the second direction when the electrical panel is fixed to the base member. By dividing the base member to which the plurality of electrical panels are fixed into multiple parts, the size of each base member can be reduced, thereby reducing the cost of manufacturing the base member and facilitating its transportation and installation. By arranging the multiple base members in contact with each other in the second direction, it is possible to prevent the spacing between the multiple electrical panels from becoming too large. By installing the multiple electrical panels with a space between them, the multiple electrical panels can be installed individually, which also contributes to shortening the construction period. For these reasons, the energy storage facility can also improve the work efficiency of the electrical panel installation work.

[0026] (9) The storage equipment described in (8) above may further include another base member arranged in contact with any one of the plurality of base members in a third direction intersecting the first direction and the second direction.

[0027] According to the electricity storage facility described in (9) above, the base members are arranged in contact with each other in the third direction, which makes it possible to prevent the gap between the electrical panels in the third direction from becoming too large.

[0028] Hereinafter, a method for manufacturing a power storage facility and a power storage facility according to an embodiment of the present invention (including its modified examples) will be described with reference to the drawings. The embodiments described below all show comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, manufacturing processes, and the order of manufacturing processes shown in the following embodiments are examples and are not intended to limit the present invention. In each drawing, dimensions and the like are not strictly illustrated. In each drawing, the same reference numerals are used to designate identical or similar components.

[0029] In the following description and drawings, the width direction of the electrical panel housing, or the direction in which the two side panels of the housing face each other, is defined as the X-axis direction. The direction in which the front or back of the electrical panel faces, the depth direction of the electrical panel housing, or the direction in which the front and rear panels of the housing face each other, is defined as the Y-axis direction. The arrangement direction of the electrical panel and the base member, the arrangement direction of the electrical panel and the air conditioning unit, the height direction of the electrical panel housing, the direction in which the top and bottom panels of the housing face each other, and the vertical direction or up-down direction are defined as the Z-axis direction. The X-axis, Y-axis, and Z-axis directions intersect each other (orthogonal in this embodiment).

[0030] In the following description, the positive X-axis direction refers to the direction of the X-axis arrow, and the negative X-axis direction refers to the direction opposite to the positive X-axis direction. Simply referring to the X-axis direction refers to both or either of the positive X-axis direction and the negative X-axis direction. The same applies to the Y-axis and Z-axis directions. Hereinafter, the Z-axis direction or the negative Z-axis direction will also be referred to as the first direction, the X-axis direction will also be referred to as the second direction, and the Y-axis direction will also be referred to as the third direction. Expressions indicating relative directions or orientations, such as parallel and perpendicular, also include cases where the directions or orientations are not strictly the same. Two directions being parallel (or perpendicular) not only means that the two directions are completely parallel (or perpendicular), but also means that the directions are substantially parallel (or perpendicular), i.e., there is a difference of, for example, a few percent. In the following description, the term "insulation" means "electrical insulation." The volume resistivity of an insulating material is 1×10 6 Ωm or more is preferable, and 1×107 Ωm or more is preferable, and 1×10 10 More preferably, it is Ωm or more.

[0031] (Embodiment) [1 General description of the energy storage facility 1] First, an overall description will be given of the energy storage facility 1 manufactured by the manufacturing method for the energy storage facility 1 according to the present embodiment. FIG. 1 is a perspective view showing the configuration of the energy storage facility 1 according to the present embodiment. FIG. 2 is a perspective view showing the configuration of four electrical panels 100, four air conditioners 200, and a base member 500 provided in the energy storage facility 1 according to the present embodiment. In FIG. 2, the front panel 113 is removed from the housing 110 of one of the electrical panels 100 (101), and the internal configuration of the housing 110 is shown by solid lines and dashed lines, as well as the base member 500 (a part of the base member 510 and the base member 520) to which the four electrical panels 100 are fixed. In FIG. 2, a positioning portion 521 provided on the base member 520, which will be described later, is not shown. FIG. 3 is a perspective view showing the configuration of the energy storage device 120 provided in the electrical panel 100 according to the present embodiment. In FIG. 3, the internal configuration of the housing 121 of the energy storage device 120 is shown by dashed lines, with the exterior body 121 of the energy storage device 120 being seen through.

[0032] The power storage facility 1 is a facility that charges and discharges electricity and supplies it to an external power load. The power storage facility 1 is a stationary battery used for business or home purposes, and is used for power storage or power supply purposes. In this embodiment, the power storage facility 1 is outdoor-spec facility that is installed outdoors (can be installed outdoors), and has dustproof and waterproof properties to the extent necessary for outdoor installation. The power storage facility 1 is installed in a large mobile object such as a ship or a railway vehicle for an electric railway, and can also be used as a battery for the large mobile object. Examples of the above-mentioned railway vehicle for an electric railway include electric trains, monorails, linear motor cars, and hybrid trains equipped with both a diesel engine and an electric motor.

[0033] 1, the power storage facility 1 includes an electrical panel 100, an air conditioner 200 arranged above the electrical panel 100, an electrical panel 300, an air conditioner 400 arranged above the electrical panel 300, and a base member 500 arranged below the electrical panels 100 and 300. Specifically, the power storage facility 1 includes a plurality of electrical panels 100, a plurality of air conditioners 200 arranged above the plurality of electrical panels 100 (positive direction of the Z axis), one electrical panel 300, and a plurality of air conditioners 400 arranged above the single electrical panel 300 (positive direction of the Z axis). The power storage facility 1 further includes a plurality of base members 510 and one base member 520 arranged below the plurality of electrical panels 100 (negative direction of the Z axis (first direction)), and one base member 530 arranged below the single electrical panel 300 (negative direction of the Z axis (first direction)). The configuration and arrangement of the base member 500 (510 to 530) will be described in detail later.

[0034] In this embodiment, ten electrical panels 100 are arranged in five sets of two electrical panels 100 arranged in the Y-axis direction in the X-axis direction, and one electrical panel 300 is located in the positive direction of the X-axis. These electrical panels 100 and 300 are arranged adjacent to each other in the X-axis direction or the Y-axis direction. "Adjacent to each other in the X-axis direction" refers to a state in which the panels are arranged relatively close to each other in the X-axis direction, and includes cases in which the panels are in contact with each other in the X-axis direction and cases in which the panels are close but not in contact with each other in the X-axis direction. The same applies to cases in which the panels are arranged adjacent to each other in the Y-axis direction. In this embodiment, the multiple electrical panels 100 and 300 are arranged at predetermined intervals in the X-axis direction and the Y-axis direction. Details will be described later. In each electrical panel 100, one air conditioner 200 is arranged above one electrical panel 100. Four air conditioners 400 are arranged above the electrical panel 300, so that two sets of two air conditioners 400 arranged in the Y-axis direction are arranged in the X-axis direction.

[0035] In this embodiment, the electrical panel 100 is a power storage panel that houses power storage elements. The electrical panel 300 is a power conversion panel that houses a power converter. Electric power received from the outside is converted by the electrical panel 300 and then supplied to the electrical panel 100, where it is charged. Electric power discharged by the electrical panel 100 is converted by the electrical panel 300 and then supplied to the outside.

[0036] Hereinafter, these multiple electrical panels 100 (storage panels) and electrical panels 300 (power conversion panels) will also be collectively referred to as electrical panels 10. The multiple air conditioners 200 and multiple air conditioners 400 will also be collectively referred to as air conditioners 20. In other words, the electrical panel 10 includes multiple electrical panels 100 (storage panels) and one electrical panel 300 (power conversion panel). The air conditioner 20 includes multiple air conditioners 200 and multiple air conditioners 400. The numbers of electrical panels 100, electrical panels 300, air conditioners 200, and air conditioners 400 are not particularly limited.

[0037] [1.1 Description of Electrical Panels 100 and 300] Next, the configurations of the electrical panels 100 and 300 will be described in detail. First, the configuration of the electrical panel 100 will be described, and then the configuration of the electrical panel 300 will be described, focusing on the parts that differ from the electrical panel 100. Since the multiple electrical panels 100 provided in the power storage facility 1 (electrical panel 10) all have the same configuration, the configuration of one electrical panel 100 will be described in detail below.

[0038] The electrical panel 100 is a device that can charge electricity from an external source and discharge electricity to an external source, and has a rectangular parallelepiped shape. The electrical panel 100 is a stationary storage panel (battery panel) that stores various types of electricity, such as power from a commercial power system, power generated by generators, wind power, or solar power, and regenerative power from railway systems, and supplies stable power to external equipment. As described above, the electrical panel 100 is an outdoor-spec facility that is installed outdoors (can be installed outdoors) and has the dustproof and waterproof properties required for outdoor installation. Specifically, the electrical panel 100 has an IP2X, IP3X, IP4X, IP5X, or IP6X dustproof rating and an IPX3, IPX4, IPX5, IPX6, IPX7, or IPX8 waterproof rating according to the protection rating (IP code) defined by the IEC (International Electrotechnical Commission) standards.

[0039] As shown in FIG. 2, the electrical panel 100 includes a housing 110 and a plurality of power storage devices 120 arranged inside the housing 110. In addition to these components, the electrical panel 100 also includes electric wires and the like that connect the plurality of power storage devices 120 to one another, but these are not shown in the drawings and will not be described in detail. In this embodiment, within the housing 110, a plurality of (six) power storage devices 120 are arranged in the X-axis direction and are arranged in multiple tiers in the Z-axis direction. The number of power storage devices 120 arranged in the X-axis direction and the number of tiers arranged in the Z-axis direction are not particularly limited. The plurality of power storage devices 120 may all be connected in series, may be connected in a combination of series and parallel, or may all be connected in parallel.

[0040] The housing 110 is a rectangular parallelepiped (box-shaped) container (shelf, rack). The housing 110 has a sealed structure. The term "sealed structure" refers to a sealed structure that provides dustproof and waterproof properties as described above, but allows for small gaps. The interior space of the housing 110 is divided into multiple sections, and multiple power storage devices 120 are housed within the divided sections. The housing 110 is made of metal such as stainless steel, aluminum, aluminum alloy, iron, or plated steel. The housing 110 may be made of a material other than metal (such as resin), but is preferably made of a material that is strong, heat-resistant, and flame-retardant. The housing 110 includes side panels 111 and 112, a front panel 113, a rear panel 114, a bottom panel 115, a top panel 116, a first shelf 117, and a second shelf 118.

[0041] The side plates 111 and 112, the front plate 113, the rear plate 114, the bottom plate 115, and the top plate 116 are flat, rectangular wall portions that cover all six sides of the housing 110. Specifically, the side plate 111 is a wall of the housing 110 facing in the negative direction on the X axis, and the side plate 112 is a wall of the housing 110 facing in the positive direction on the X axis. The front plate 113 is a wall of the housing 110 facing in the negative direction on the Y axis. The front plate 113 is a cover member (door) that can be opened and closed (opened and closed freely) to close an opening on the surface (front face) of the housing 110 facing in the negative direction on the Y axis. The rear plate 114 is a wall of the housing 110 facing in the positive direction on the Y axis. The bottom plate 115 is a wall of the housing 110 facing in the negative direction on the Z axis. The top plate 116 is a wall of the housing 110 facing in the positive direction on the Z axis.

[0042] Through holes are formed in the lower parts of the side plates 111 and 112. As shown in FIG. 2 , of the four electrical boards 100, the electrical board 100 located in the positive direction of the X axis and the negative direction of the Y axis is also referred to as electrical board 101, and the electrical board 100 located in the negative direction of the X axis and the negative direction of the Y axis is also referred to as electrical board 102. The electrical boards 101 and 102 are adjacent to each other in the X axis direction. In this case, in the housing 110 provided for the electrical board 101, a through hole 111a is formed in the lower part of the side plate 111, and a through hole 112a is formed in the lower part of the side plate 112. In the housing 110 provided for the electrical board 102, a through hole 112b is formed in the lower part of the side plate 112 (the through hole in the lower part of the side plate 111 is not shown in the drawing).

[0043] As a result, through-hole 111a of electrical panel 101 and through-hole 112b of electrical panel 102 are arranged opposite each other, and through-holes 111a and 112b are configured so that through-holes 111a and 112b are penetrated by through-hole members 30, which are wiring or piping. The through-holes 30 include at least one of main circuit wiring, signal lines, grounding lines, commercial AC wiring, control power lines, cooling piping, heating piping, and fire extinguishing piping. The through-holes 111a and 112b are sealed by a cover 40 that covers the periphery of the through-hole member 30, thereby maintaining the above-mentioned dustproof and waterproof properties. The same applies to other through-holes such as through-hole 112a.

[0044] A vent (not shown) through which the air conditioner 200 takes in and exhausts air is formed in the top plate 116 at a position facing the air conditioner 200. The air conditioner 200, which is disposed above the top plate 116, circulates air in the internal space of the electrical panel 100 via the vent. That is, the air conditioner 200 exhausts temperature-adjusted air into the internal space of the electrical panel 100, circulates the air in the internal space of the electrical panel 100, and then takes it into the air conditioner 200. The vent is sealed between the air conditioner 200 and the vent, thereby maintaining the above-mentioned dustproofness and waterproofness.

[0045] The first shelf 117 and the second shelf 118 are walls that divide the space inside the housing 110. Each power storage device 120 is disposed inside the housing 110 by being supported by the first shelf 117 and the second shelf 118 within the space divided by the first shelf 117 and the second shelf 118. A plurality of power storage devices 120 are arranged in the X-axis direction on the first shelf 117, and a plurality of power storage devices 120 are arranged in the X-axis direction on the second shelf 118. A space in the negative Z-axis direction of the first shelf 117 where no power storage devices 120 are disposed is formed, and an electric unit (electrical component) that controls all of the power storage devices 120 is disposed therein. In this embodiment, the first shelf 117 and the second shelf 118 are flat, rectangular wall portions. An opening (not shown) is formed in the second shelf 118, and air circulating in the interior space of the electrical panel 100 can pass through the opening. No openings are formed in the first shelf 117, and the air circulating in the internal space of the electrical panel 100 cannot pass through the space in the negative Z-axis direction of the first shelf 117. The shapes of the first shelf 117 and the second shelf 118 are not particularly limited, and they may be narrow plate-like or rod-like members such as beams.

[0046] Next, the configuration of the energy storage device 120 will be described in detail. The energy storage device 120 is a battery module (battery assembly) having a substantially rectangular parallelepiped shape that is elongated in the Y-axis direction. The longitudinal direction of the energy storage device 120 is the Y-axis direction. As shown in FIG. 3, the energy storage device 120 includes an exterior body 121, a plurality of energy storage elements 122, and a substrate unit 123. In this embodiment, the plurality of energy storage elements 122 are arranged side by side in the Y-axis direction, but the arrangement direction and the number of the energy storage elements 122 are not particularly limited, and only one energy storage element 122 may be arranged. In addition to these components, the energy storage device 120 also includes bus bars and the like that connect terminals of the plurality of energy storage elements 122 to each other, but these are not shown in the drawings and detailed description will also be omitted. The energy storage device 120 may also include a pair of external terminals (positive and negative) for connecting to the outside, spacers arranged between the energy storage elements 122, restraining members (end plates, side plates, etc.) for restraining the energy storage elements 122, a bus bar frame for positioning the bus bar, etc., but these are not shown or described here.

[0047] The exterior body 121 is a box-shaped (rectangular parallelepiped) container (module case) that is elongated in the Y-axis direction and that constitutes the outer shell of the power storage device 120. The exterior body 121 houses the multiple energy storage elements 122, fixes the multiple energy storage elements 122 in predetermined positions, and protects them from impacts and the like. The exterior body 121 is formed from an insulating material such as resin, and prevents the energy storage elements 122 from coming into contact with external metal members and the like. The exterior body 121 may be formed from a conductive material such as metal, as long as the insulating properties of the energy storage elements 122 are maintained.

[0048] The energy storage element 122 is a secondary battery (single cell) that can charge and discharge electricity, and more specifically, is a non-aqueous electrolyte secondary battery such as a lithium ion secondary battery. In this embodiment, the energy storage element 122 has a flattened rectangular parallelepiped (square) shape, but the shape of the energy storage element 122 is not limited to a rectangular parallelepiped shape and may be a polygonal prism shape other than a rectangular parallelepiped, a cylindrical shape, an elongated cylindrical shape, an elliptical cylindrical shape, or the like. The energy storage element 122 may be a secondary battery other than a non-aqueous electrolyte secondary battery, or may be a capacitor. The energy storage element 122 may be a primary battery. The energy storage element 122 may be a battery using a solid electrolyte. The energy storage element 122 may be a pouch-type energy storage element.

[0049] The board unit 123 is a device that can monitor the states of the energy storage elements 122, such as the charge state and discharge state, and control the energy storage elements 122. The board unit 123 has electrical equipment such as a circuit board (CMU: Cell Management Unit) inside. In this embodiment, the board unit 123 is a flat rectangular member that is attached to the end of the exterior body 121 on the negative Y-axis direction, and is thereby disposed at the end of the energy storage device 120 on the negative Y-axis direction.

[0050] Next, a detailed description will be given of the configuration of the electrical panel 300. The electrical panel 300 is a stationary power conversion panel (PCS panel, power conditioner) that has a housing similar to the electrical panel 100 and has a power converter and copper bars (not shown) inside the housing.

[0051] The housing of the electrical panel 300, like the housing 110 of the electrical panel 100, has six flat, rectangular walls: two side panels, a front panel, a rear panel, a bottom panel, and a top panel. Of the two side panels of the housing of the electrical panel 300, the side panel facing the electrical panel 100 has a through-hole (not shown) formed in the lower part, like the side panels 111 and 112 of the housing 110 of the electrical panel 100. The top panel of the housing of the electrical panel 300 has a vent hole (not shown) formed therein for the air conditioner 400 to take in and exhaust, like the top panel 116 of the housing 110 of the electrical panel 100. As such, the housing of the electrical panel 300 has a similar configuration to the housing 110 of the electrical panel 100, and therefore a detailed description thereof will be omitted.

[0052] The power converter and copper bars included in the electrical panel 300 may be any known power converter and copper bar. The power converter is electrically connected to the power storage device 120 included in the electrical panel 100 and converts power to or from the electrical panel 100. The power converter converts AC power to DC power (AC-DC conversion), converts DC power to AC power (DC-AC conversion), or converts voltage or frequency to a different value (DC-DC conversion, AC-AC conversion). In this embodiment, the power converter converts power to the electrical panel 100 from AC power to DC power and adjusts the voltage of the power, and converts power from the electrical panel 100 from DC power to AC power and adjusts the voltage of the power. The electrical panel 300 may also include electrical equipment (electrical components) such as a breaker.

[0053] 1.2 Description of Air Conditioners 200 and 400 Next, the configurations of the air conditioners 200 and 400 will be described in detail. First, the configuration of the air conditioner 200 will be described, and then the configuration of the air conditioner 400 will be described, focusing on the differences from the air conditioner 200. The multiple air conditioners 200 included in the power storage facility 1 (air conditioners 20) all have the same configuration, and the multiple air conditioners 400 all have the same configuration.

[0054] The air conditioner 200 is a device having at least one of a cooling function and a heating function. In this embodiment, the air conditioner 200 has both a cooling function and a heating function, and performs cooling or heating by switching between cooling operation and heating operation. From the viewpoint of cost reduction, the air conditioner 200 may be equipped with an air conditioner (cooler) dedicated to cooling and a heater separate from the air conditioner. In this case, the air conditioner 200 may stop the exhaust fan when the heater is in use. In this embodiment, the air conditioner 200 is a heat exchange type air conditioner.

[0055] 2, the air conditioner 200 is disposed above the top plate 116 of the housing 110 of the electrical panel 100. The air conditioner 200 circulates air in the internal space of the electrical panel 100 through vent holes (not shown) formed in the top plate 116. In this embodiment, the air conditioner 200 is disposed above the top plate 116 while in contact with (resting on) the top plate 116. The air conditioner 200 may also be disposed above the top plate 116 while being spaced apart from the top plate 116, for example, by disposing another member between the air conditioner 200 and the top plate 116.

[0056] During cooling, the air conditioner 200 exhausts cooled air into the interior of the electrical panel 100, uses the air to cool the power storage device 120 located in the internal space of the electrical panel 100, and then draws heated air into the air conditioner 200. During heating, the air conditioner 200 exhausts heated air into the interior of the electrical panel 100, uses the air to heat the internal space of the electrical panel 100, and then draws cooled air into the air conditioner 200. The air conditioner 200 cools or heats the power storage device 120 (particularly the power storage element 122; the same applies below) inside the electrical panel 100 by cooling or heating the internal space of the electrical panel 100. In cold regions, the air conditioner 200 heats the power storage device 120 inside the electrical panel 100 by heating, and when the temperature of the power storage device 120 becomes high, cools the power storage device 120 by cooling.

[0057] The air conditioner 200 has a configuration in which the indoor unit and outdoor unit of a heat exchange type air conditioner are integrated into the same case. For this reason, the air conditioner 200 is provided with an external air intake vent 220 and an external exhaust vent 230 that communicate with the ambient air around the electrical panel 100. The external air intake vent 220 is an opening for drawing in external air around the electrical panel 100, and the external exhaust vent 230 is an opening for exhausting air to the ambient air around the electrical panel 100. A hood or the like may be provided on the external air intake vent 220 or the external exhaust vent 230 to prevent snow accumulation or snow blowing from the side.

[0058] Like the air conditioner 200, the air conditioner 400 has both cooling and heating functions. The air conditioner 400 is disposed above the top plate of the electrical panel 300. The air conditioner 400 circulates air in the interior space of the electrical panel 300 through vents (not shown) formed in the top plate of the electrical panel 300. The air conditioner 400 cools or heats the interior space of the electrical panel 300, thereby cooling or heating the power converters and other components inside the electrical panel 300. The air conditioner 400 may be configured to have only a cooling function if it is not necessary to heat the power converters and other components inside the electrical panel 300. Like the air conditioner 200, the air conditioner 400 has an external air intake vent 420 and an external air exhaust vent 430 that communicate with the air surrounding the electrical panel 300 (see FIG. 1). The configurations of the external intake port 420 and the external exhaust port 430 provided in the air conditioner 400 are similar to the external intake port 220 and the external exhaust port 230 provided in the air conditioner 200, and therefore detailed description thereof will be omitted.

[0059] [2. Description of base member 500 (510 to 530)] Next, the configuration of the base members 500 (510 to 530) and their positional relationship with the electrical panels 100 and 300 will be described in detail. FIG. 4 is a plan view showing the configuration of the base members 500 (510 to 530) included in the energy storage facility 1 according to this embodiment in a separated state. FIG. 4 is a view of the multiple base members 500 (510 to 530) shown in FIG. 1 separated and viewed from the positive direction of the Z axis. FIG. 5 is a plan view showing the configuration of the base members 500 (510 to 530) included in the energy storage facility 1 according to this embodiment in an assembled state. FIG. 5 is a view of the multiple base members 500 (510 to 530) shown in FIG. 1 assembled and viewed from the positive direction of the Z axis. FIG. 6 is a plan view showing the positional relationship between the base members 500 (510 to 530) according to this embodiment and the electrical panels 100 and 300. Fig. 6 is a view from the positive direction of the Z axis showing the state in which the electrical panels 100 and 300 are installed on the base members 510 to 530 shown in Fig. 1. For ease of explanation, the air conditioners 200 and 400 are not shown in Fig. 6.

[0060] [2.1 Description of the configuration of the base member 500 (510 to 530)] The base member 500 is a member that is flattened in the Z-axis direction and has a rectangular shape when viewed from the Z-axis direction. As shown in Fig. 4, the energy storage facility 1 includes, as the base member 500, four base members 510, one base member 520, and one base member 530. Specifically, the energy storage facility 1 includes four base members 510, each of which has two base members 510 aligned in the Y-axis direction and arranged in two sets in the X-axis direction, one base member 520 located in the positive direction of the X-axis, and one base member 530 located in the positive direction of the X-axis.

[0061] The base member 510 is a rectangular member parallel to the XY plane extending in the X-axis direction when viewed from the Z-axis direction. The base member 510 in the positive Y-axis direction has a shape obtained by rotating the base member 510 in the negative Y-axis direction by 180° about the Z-axis. Each base member 510 has two openings 510a, which are rectangular through-holes, aligned in the X-axis direction. This gives the base member 510 a frame-like shape in plan view (when viewed from the Z-axis direction). In other words, the base member 510 has a shape such that a beam extending in the Y-axis direction is provided in the center of a rectangular ring-shaped outer frame surrounding the periphery in the X-axis direction. The number, shape, size, etc. of the openings 510a formed in the base member 510 are not particularly limited, and the base member 510 may have any frame shape. The base member 510 may include multiple members (such as H-beams) and may be formed by combining and joining the multiple members.

[0062] The base member 510 includes positioning portions 511 and 512 for positioning the electrical board 100 on the base member 510. In this embodiment, the positioning portion 511 is a protrusion (positioning pin) that is disposed in the center of the base member 510 in the X-axis direction and protrudes in the positive direction of the Z-axis. Two positioning portions 511 that are aligned in the Y-axis direction are disposed between the two openings 510a. The positioning portion 512 is a protrusion that is disposed at the end of the base member 510 in the X-axis direction and protrudes in the positive direction of the Z-axis. On the base member 510 facing the negative Y-axis direction, two positioning portions 512 that are aligned in the Y-axis direction are disposed at the end of the base member 510 in the positive X-axis direction. On the base member 510 facing the positive Y-axis direction, two positioning portions 512 that are aligned in the Y-axis direction are disposed at the end of the base member 510 in the negative X-axis direction. As a result, the positioning portions 511 and 512 restrict movement of the electrical board 100 in the X-axis direction relative to the base member 510. There are no particular limitations on the number, shape, size, and arrangement positions of the positioning portions 511 and 512. In this embodiment, the positioning portions 511 and 512 are arranged on the outer side of the base member 510 in the Y axis direction, but they may also be arranged in the center of the base member 510 in the Y axis direction or on the inner side in the Y axis direction. The positioning portions 511 and 512 may be portions that are integrated with the base member 510, or may be members that are separate from the base member 510.

[0063] The base member 520 is a rectangular member parallel to the XY plane when viewed from the Z-axis direction. The base member 520 has three openings 520a, which are rectangular through-holes aligned in the Y-axis direction. This gives the base member 520 a frame-like shape when viewed from the plan view (when viewed from the Z-axis direction). In other words, the base member 520 has a shape in which two beams extending in the X-axis direction are provided at the center in the Y-axis direction of a rectangular ring-shaped outer frame surrounding the outer periphery. The number, shape, size, etc. of the openings 520a formed in the base member 520 are not particularly limited, and the base member 520 may be a member of any frame shape. The base member 520 may include a plurality of members (such as H-beams) and may be formed by combining and joining the plurality of members.

[0064] The base member 520 includes positioning portions 521 and 522 for positioning the electrical board 100 on the base member 520. In this embodiment, the positioning portion 521 is a protrusion (positioning pin) that protrudes in the positive direction of the Z axis and is disposed at the end of the base member 520 in the positive direction of the X axis of the end in the negative direction of the Y axis. Two positioning portions 521 are disposed at the end of the base member 520 in the positive direction of the X axis of the end in the negative direction of the Y axis, aligned in the Y axis direction. The positioning portion 522 is a protrusion that protrudes in the positive direction of the Z axis and is disposed at the end of the base member 520 in the negative direction of the X axis of the end in the positive direction of the Y axis. Two positioning portions 522 are disposed at the end of the base member 520 in the negative direction of the X axis of the end in the positive direction of the Y axis of the base member 520, aligned in the Y axis direction. As a result, the positioning portions 521 and 522 limit movement of the electrical board 100 in the X axis direction relative to the base member 520. The number, shape, size, and arrangement position of the positioning portions 521 and 522 are not particularly limited. The positioning portion 521 may be disposed at the end of the base member 520 in the negative X-axis direction, and the positioning portion 522 may be disposed at the end of the base member 520 in the positive X-axis direction. The positioning portions 521 and 522 may be integral with the base member 520, or may be separate members from the base member 520.

[0065] The base member 530 is a rectangular member parallel to the XY plane when viewed from the Z-axis direction. The base member 530 has three openings 530a, which are rectangular through-holes aligned in the Y-axis direction. This gives the base member 530 a frame-like shape when viewed from the plan view (when viewed from the Z-axis direction). In other words, the base member 530 has a shape in which two beams extending in the X-axis direction are provided in the center of a rectangular ring-shaped outer frame surrounding the periphery in the Y-axis direction. The number, shape, size, etc. of the openings 530a formed in the base member 530 are not particularly limited, and the base member 530 may be a member of any frame shape. The base member 530 may include a plurality of members (such as H-beams) and may be formed by combining and joining the plurality of members.

[0066] The base member 530 includes positioning portions 531 and 532 for positioning the electrical board 300 on the base member 530. In this embodiment, the positioning portion 531 is a protrusion (positioning pin) that protrudes in the positive direction of the Z axis and is disposed at the end of the base member 530 in the negative X-axis direction at the end of the base member 530 in the negative Y-axis direction. Two positioning portions 531 are disposed at the end of the base member 530 in the negative X-axis direction at the end of the base member 530 in the negative Y-axis direction, aligned in the Y-axis direction. The positioning portion 532 is a protrusion that protrudes in the positive Z-axis direction and is disposed at the end of the base member 530 in the negative X-axis direction at the end of the base member 530 in the positive Y-axis direction. Two positioning portions 532 are disposed at the end of the base member 530 in the negative X-axis direction, aligned in the Y-axis direction. As a result, the positioning portions 531 and 532 limit movement of the electrical board 300 in the X-axis direction relative to the base member 530. The number, shape, size, and arrangement position of the positioning portions 531 and 532 are not particularly limited. The positioning portion 531 may be disposed at the end of the base member 530 in the positive direction of the X axis, and the positioning portion 532 may be disposed at the end of the base member 530 in the positive direction of the X axis. The positioning portions 531 and 532 may be integral with the base member 530, or may be separate members from the base member 530.

[0067] The length of base member 510 in the Y-axis direction is shorter than half the length of base member 520 in the Y-axis direction and shorter than half the length of base member 530 in the Y-axis direction. In other words, the outer dimensions of base member 510 in the Y-axis direction are smaller than half the outer dimensions of base member 520 and smaller than half the outer dimensions of base member 530. The length of base member 520 in the Y-axis direction is the same as the length of base member 530 in the Y-axis direction. In other words, the outer dimensions of base member 520 in the Y-axis direction are the same as the outer dimensions of base member 530.

[0068] In this configuration, as shown in FIG. 5, two base members 510 aligned in the X-axis direction are arranged in contact with each other in the X-axis direction. Two base members 510 and a base member 520 aligned in the positive direction of the X-axis are arranged in contact with each other in the X-axis direction. A base member 520 and a base member 530 are arranged in contact with each other in the X-axis direction. That is, the energy storage facility 1 includes a plurality of base members 500 (510 to 530) aligned in the X-axis direction (a second direction intersecting with the first direction), and these plurality of base members 500 (510 to 530) are arranged in contact with each other in the X-axis direction (the second direction). Two base members 510 aligned in the Y-axis direction are arranged spaced apart from each other in the Y-axis direction. That is, one base member (base member 510) among the plurality of base members 500 (510 to 530) is arranged spaced apart from the other base members (other base members 510) in the Y-axis direction (a third direction intersecting with the first and second directions).

[0069] The base members 510, 520, and 530 in the negative Y-axis direction are arranged so that their edge in the negative Y-axis direction is at the same position in the Y-axis direction (arranged in a straight line along the X-axis direction). In other words, the base members 510, 520, and 530 in the negative Y-axis direction have the end faces (front faces) in the negative Y-axis direction aligned in the Y-axis direction. The base members 510, 520, and 530 in the positive Y-axis direction have the end edges in the positive Y-axis direction aligned in the Y-axis direction (arranged in a straight line along the X-axis direction). In other words, the base members 510, 520, and 530 in the positive Y-axis direction have the end faces in the positive Y-axis direction aligned in the Y-axis direction.

[0070] [2.2 Explanation of the positional relationship between the base member 500 and the electrical panels 100 and 300] As shown in FIG. 6 , electrical boards 100 are fixed on base members 510 and 520, and an electrical board 300 is fixed on base member 530. Specifically, two electrical boards 100 lined up in the X-axis direction are fixed on one base member 510. The two electrical boards 100 are positioned in the X-axis direction by positioning portions 511 and 512 of the base member 510, restricting their movement in the X-axis direction. Two electrical boards 100 lined up in the Y-axis direction are fixed on one base member 520. The two electrical boards 100 are positioned in the X-axis direction by positioning portions 521 and 522 of the base member 520, restricting their movement in the X-axis direction. In this way, the two electrical boards 100 are fixed side by side on one base member 510 of the multiple base members 500. The two electrical boards 100 are fixed side by side on one base member 520 of the multiple base members 500. One electrical board 300 is fixed onto one base member 530. The movement of the one electrical board 300 in the X-axis direction is restricted by positioning portions 531 and 532 of the base member 530, and the electrical board 300 is positioned in the X-axis direction.

[0071] In this embodiment, the electrical panel 100 is fixed to the base member 510 by bolting or the like, but the fixing means is not particularly limited and may be fixed by welding, crimping, a fitting structure, an engagement (hooking) structure, or the like. In this embodiment, the base member 510 is provided with a fixing portion (not shown) for the electrical panel 100. Specifically, a nut is welded to the base member 510. A through hole (not shown) is also provided on the bottom surface of the electrical panel 100 as a fixing portion, and the base member 510 and the electrical panel 100 are fixed by fastening the fixing portion of the base member 510 to the fixing portion of the electrical panel 100 with a bolt. This also determines the position of the electrical panel 100 on the base member 510. In this way, the electrical panel 100 is positioned by the fixing portion, but positioning can be made even easier by the positioning portions 511 and 512. The same applies to the fixing of the electrical panel 100 to the base member 520 and the fixing of the electrical panel 300 to the base member 530.

[0072] The length of the base member 510 in the X-axis direction is longer than the length of the two electrical boards 100 in the X-axis direction (twice the length of one electrical board 100 in the X-axis direction). In other words, the outer dimension of the base member 510 in the X-axis direction (second direction) is larger than the outer dimension of the electrical board 100. Specifically, the outer dimension of the base member 510 in the X-axis direction is more than twice the outer dimension of the electrical board 100. As a result, the base member 510 protrudes from the electrical board 100 on both sides in the X-axis direction. The length of the base member 520 in the X-axis direction is longer than the length of the electrical board 100 in the X-axis direction. In other words, the outer dimension of the base member 520 in the X-axis direction (second direction) is larger than the outer dimension of the electrical board 100. As a result, the base member 520 protrudes from the electrical board 100 on both sides in the X-axis direction. The length of the base member 530 in the X-axis direction is longer than the length of the electrical board 300 in the X-axis direction. That is, the outer dimensions of the base member 530 in the X-axis direction (second direction) are larger than the outer dimensions of the electrical panel 300. As a result, the base member 530 protrudes from the electrical panel 300 on both sides in the X-axis direction.

[0073] In this configuration, two electrical boards 100 are fixed on the base member 510 at a predetermined interval (distance S1 in FIG. 6) in the X-axis direction (second direction). Of two base members 510 adjacent to each other in the X-axis direction, the electrical board 100 in the positive X-axis direction on the base member 510 in the negative X-axis direction and the electrical board 100 in the negative X-axis direction on the base member 510 in the positive X-axis direction are fixed at a predetermined interval (distance S2 in FIG. 6) in the X-axis direction (second direction). The electrical board 100 in the positive X-axis direction on the base member 510 adjacent to the base member 520 and the electrical board 100 on the base member 520 are fixed at a predetermined interval (distance S3 in FIG. 6) in the X-axis direction (second direction). The electrical board 100 on the base member 520 and the electrical board 300 on the base member 530 are fixed at a predetermined interval (distance S4 in FIG. 6) in the X-axis direction (second direction). As a result, all of the multiple electrical boards 100 and 300 lined up in the X-axis direction are arranged at predetermined intervals in the X-axis direction.

[0074] The "predetermined interval" mentioned above is an interval of any size, and is determined appropriately by the user. The same applies to the "predetermined interval" hereinafter. In this embodiment, all of the intervals S1 to S4 are set to be the same size. The intervals S1 to S4 are preferably gaps between 20 mm and 300 mm, and more preferably gaps between 50 mm and 200 mm. Any of the intervals S1 to S4 may be gaps of different sizes.

[0075] In two base members 510 adjacent to each other in the Y-axis direction, the electrical board 100 on one base member 510 and the electrical board 100 on the other base member 510 are fixed at a predetermined distance in the Y-axis direction (distance S5 in FIG. 6 ). In this embodiment, the two electrical boards 100 are fixed side by side on the two base members 510 so that the rear panels 114 of the housings 110 of the two electrical boards 100 (back surfaces) face each other. Two electrical boards 100 are fixed on the base member 520 at a predetermined distance in the Y-axis direction (distance S5 in FIG. 6 ). The distance S5 between the two electrical boards 100 on the base member 520 may be different from the distance S5 between the other two electrical boards 100. In other words, the two electrical boards 100 are fixed side by side on one base member 520 so that the rear panels 114 of the two electrical boards 100 (back surfaces) face each other. As a result, all of the electrical panels 100 aligned in the Y-axis direction are arranged at predetermined intervals in the Y-axis direction.

[0076] The interval S5 may be the same as or different from the intervals S1 to S4. The interval S5 is preferably a gap of 50 mm or more and 600 mm or less, and more preferably 50 mm or more and 200 mm or less. The interval between any two electrical panels 100 aligned in the Y-axis direction may be a gap of a different size from the interval S5.

[0077] In this way, the spacing S1 is the spacing between two electrical boards 100 lined up in the X-axis direction and arranged on one base member 500 (510). The spacing between the two electrical boards 100 is determined with relatively high precision by the above-mentioned fixing portions and positioning portions. The spacings S2, S3, and S4 are the spacing between two electrical boards 100 lined up in the X-axis direction, set by contacting two base members 500 lined up in the X-axis direction. In this case, too, the spacing between the two electrical boards 100 is determined with relatively high precision by the above-mentioned fixing portions and positioning portions. The spacing S5 between two electrical boards 100 on the base member 520 is the spacing between two electrical boards 100 lined up in the Y-axis direction and arranged on one base member 500 (520). In this case, the spacing between the two electrical boards 100 is determined with relatively high precision by the above-mentioned fixing portions. The other spacing S5 is the spacing between two electrical panels 100 aligned in the Y-axis direction when there is a spacing between two base members 500 (510) aligned in the Y-axis direction. In this case, the spacing between the two electrical panels 100 is not determined with high precision, so the dimensional tolerance is set relatively large.

[0078] With this configuration, the edges of the multiple electrical boards 100 lined up in the X-axis direction are positioned at the same position in the Y-axis direction (aligned in a straight line along the X-axis direction). In other words, the positions of the front panels 113 (front surfaces) of the housings 110 in the Y-axis direction are aligned for the multiple electrical boards 100 lined up in the X-axis direction. In this embodiment, the positions of the rear panels 114 (rear surfaces) of the housings 110 in the Y-axis direction are also aligned for the multiple electrical boards 100 lined up in the X-axis direction. The positions of the front panels 113 (front surfaces) of the electrical boards 100 and the front panels (front surfaces) of the electrical boards 300 in the Y-axis direction are also aligned.

[0079] As long as the electrical panels 100 and 300 can be arranged as described above, the lengths of the base members 510 to 530 in the Y-axis direction are not particularly limited, but in this embodiment, they are as follows. The length of the base member 510 in the Y-axis direction is the same as the length of the electrical panel 100 in the Y-axis direction. In other words, the outer dimensions of the base member 510 in the Y-axis direction are the same as the outer dimensions of the electrical panel 100. The length of the base member 520 in the Y-axis direction is longer than the lengths of the two electrical panels 100 in the Y-axis direction (twice the length of one electrical panel 100 in the Y-axis direction). In other words, the outer dimensions of the base member 520 in the Y-axis direction are larger than the outer dimensions of the electrical panel 100. Specifically, the outer dimensions of the base member 520 in the Y-axis direction are more than twice the outer dimensions of the electrical panel 100. The length of the base member 530 in the Y-axis direction is the same as the length of the electrical panel 300 in the Y-axis direction. In other words, the base member 530 has the same external dimensions as the electrical panel 300 in the Y-axis direction.

[0080] [3. Description of the manufacturing method of the energy storage device 1] Next, a method for manufacturing the power storage facility 1 in this embodiment will be described. Specifically, among the methods for manufacturing the power storage facility 1, a step of arranging a plurality of base members 500 and fixing a plurality of electrical panels 100, 300 on the plurality of base members 500 will be described in detail.

[0081] First, as shown in Fig. 4, base members 500 (510 to 530) whose outer dimensions in the X-axis direction (second direction intersecting the first direction) are larger than the outer dimensions of the electrical panels 100, 300 are prepared (hereinafter also referred to as the "preparation step"). In other words, the manufacturing method of the energy storage equipment 1 includes this "preparation" (preparation step). The specific sizes of the base members 500 (510 to 530) are as described above.

[0082] Next, as shown in Fig. 5, a plurality of base members 500 (510 to 530) are arranged side by side in the X-axis direction (second direction) (hereinafter also referred to as the "arranging step"). That is, the manufacturing method of the energy storage equipment 1 includes this "arranging (side by side)" (arranging step). In this "arranging (side by side)" (arranging step), the plurality of base members 500 (510 to 530) are arranged in contact with each other in the X-axis direction (second direction).

[0083] 5, one of the plurality of base members 500 is spaced apart from the other base members 500 in the Y-axis direction (a third direction intersecting the first and second directions) (hereinafter also referred to as a "spaced apart step"). That is, the manufacturing method of the energy storage equipment 1 further includes this "spaced apart" (spaced apart step). In this "spaced apart" (spaced apart step), the plurality of base members 510 are spaced apart from each other in the Y-axis direction.

[0084] Next, as shown in FIG. 6 , the electrical boards 100, 300 are fixed onto each base member 500, thereby fixing the multiple electrical boards 100, 300 to the multiple base members 500 (hereinafter also referred to as the "fixing process"). In other words, the manufacturing method of the energy storage facility 1 further includes this "fixing" (fixing process). In this "fixing" (fixing process), at least one electrical board 100 or 300 is fixed onto each base member 500. In this "fixing" (fixing process), the multiple electrical boards 100, 300 are fixed at predetermined intervals in the X-axis direction (second direction). In the "fixing" (fixing process), the multiple electrical boards 100 are also fixed at predetermined intervals in the Y-axis direction. The "predetermined intervals" are as described above.

[0085] In the "fixing" (fixing process), two electrical boards 100 are fixed side by side on one of the multiple base members 500. In the "fixing" (fixing process), the two electrical boards 100 are fixed side by side on one base member 500 so that the back faces of the two electrical boards 100 face each other. Specifically, the two electrical boards 100 are fixed side by side on one base member 510 in the X-axis direction. The two electrical boards 100 are fixed side by side on one base member 520 in the Y-axis direction. In this case, the two electrical boards 100 are fixed side by side on one base member 520 so that the rear panels 114 (back faces) of the two electrical boards 100 face each other.

[0086] In the "fixing" (fixing process), the electrical boards 100, 300 are fixed onto each base member 500 using the positioning portions provided on each base member 500. Specifically, the electrical board 100 is positioned on the base member 510 by contacting the electrical board 100 in the X-axis direction with the positioning portions 511 and 512 provided on the base member 510, and the electrical board 100 is fixed onto the base member 510. The same applies to the fixing of the electrical board 100 using the positioning portions 521 and 522 of the base member 520, and the fixing of the electrical board 300 using the positioning portions 531 and 532 of the base member 530.

[0087] [4. Explanation of effects] As described above, according to the manufacturing method of the energy storage facility 1 according to the embodiment of the present invention, a plurality of base members 500 having outer dimensions in the X-axis direction (second direction) larger than the outer dimensions of the electrical panels 100, 300 are arranged in contact with each other in the X-axis direction (second direction). A plurality of electrical panels 100, 300 are fixed to the plurality of base members 500 at predetermined intervals in the X-axis direction (second direction). Even if the installation surface of the electrical panels 100, 300 is distorted, uneven, or tilted, or if the dimensional error of the electrical panels 100, 300 is large, installing the plurality of electrical panels 100, 300 at predetermined intervals can prevent problems such as interference between the electrical panels 100, 300. This allows the electrical panels 100, 300 to be easily installed, thereby improving the work efficiency of the installation work of the electrical panels 100, 300. In particular, by fixing the electrical panels 100, 300 to a base member 500 whose outer dimensions in the X-axis direction (second direction) are larger than those of the electrical panels 100, 300, multiple electrical panels 100, 300 can be easily installed at a predetermined interval in the X-axis direction (second direction). By dividing the base member 500 that fixes multiple electrical panels 100, 300 into multiple parts, the size of each base member 500 can be reduced, making it possible to manufacture the base member 500 inexpensively and facilitating transportation and installation of the base member 500. By arranging multiple base members 500 in contact with each other in the X-axis direction (second direction), it is possible to prevent the intervals between the multiple electrical panels 100, 300 from becoming too large. Installing multiple electrical panels 100, 300 at intervals allows the multiple electrical panels 100, 300 to be installed individually, which also contributes to shortening the construction period. These factors also improve the work efficiency of the installation work of the electrical panels 100, 300.

[0088] Specifically, the following applies. When installing an electrical panel outdoors, the concrete, H-beam, steel plate, or other surface on which the electrical panel is installed may be uneven, making it necessary to place a base member below the electrical panel to align the level (height, gradient, etc.). Placing a base member also serves as a water-proofing measure for the electrical panel. Conventionally, to save space, electrical panels have typically been installed on a base member so that they are in contact with each other along the X-axis. However, in this case, if the installation surface of the electrical panel is distorted, uneven, or tilted, or if the electrical panel has large dimensional errors, the electrical panels may interfere with each other, making installation difficult. In other words, conventionally, electrical panels have typically been installed in contact with each other to save space, and there has been no thought of intentionally installing electrical panels at a distance from each other. However, in this case, installing electrical panels at a predetermined distance from each other may result in reduced work efficiency. Even in the past, electrical panels have sometimes been intentionally installed at a large distance from each other to ensure wiring and other installation space or work space, but this required a large amount of space. In this case, the base members 500 are also arranged spaced apart. In this embodiment, the base members 500 are arranged in contact with each other, and the electrical panels 100, etc. are installed on the base members 500 with a predetermined distance between them. In other words, in this embodiment, although the base members 500 are arranged in contact with each other, it is important that the electrical panels 100 on the base members 500 are installed with a distance between them. This prevents problems such as interference between the electrical panels 100, etc., even if the installation surface of the electrical panels 100 is distorted, and the electrical panels 100, 300 can be easily installed. Therefore, the work efficiency in the installation work of the electrical panels 100, 300 can be improved. Space savings can also be achieved compared to conventional methods.

[0089] By placing the electrical panels 100 at a predetermined distance from each other, the following effects can be achieved. When placing the cover 40 between the electrical panels 100, the gap between the electrical panels 100 can be controlled, making it easier to place the cover 40 between the electrical panels 100. In other words, since the base members 500 are placed in contact with each other (since no space is included), the dimensions of the gap are determined by the base members 500. The fixed positions of the base members 500 and the electrical panels 100 are also determined by the fixing portions and positioning portions described above, so the gap between the electrical panels 100 is also precisely determined. Therefore, the cover 40 can be easily placed between the electrical panels 100, and the cover 40 can be installed while maintaining a sealed structure without any gaps. Therefore, it is easier to place the penetration member 30 between the electrical panels 100. Having gaps between the electrical panels 100 makes it easier to insert and remove the electrical panels 100 when repairing or replacing them, facilitating the repair or replacement work of the electrical panels 100. If the electrical panel 100 or the like has a sealed structure, heat tends to build up inside the electrical panel 100 or the like, but even in this case, the heat can be dissipated through gaps between the electrical panels 100 or the like.

[0090] According to the manufacturing method of the energy storage facility 1, by fixing two electrical panels 100 side by side on one base member 500, it is possible to reduce the number of base members 500 compared to disposing a base member 500 for each electrical panel 100. This makes it possible to reduce assembly tolerances that arise when the base members 500 are juxtaposed. By fixing two electrical panels 100 side by side on one base member 500, the two electrical panels 100 can be installed in desired positions, such as by being spaced apart.

[0091] According to the manufacturing method of the energy storage facility 1, two electrical panels 100 are fixed side by side on one base member 500 with their back surfaces facing each other. In other words, two rows of electrical panels 100 can be installed side by side with their back surfaces facing each other using one base member 500. This makes it possible to omit the placement of the base member 500 when installing the second row of electrical panels 100.

[0092] According to the manufacturing method of the energy storage equipment 1, by arranging the base members 500 at intervals in the Y-axis direction (third direction), dimensional tolerances of the base members 500 in the Y-axis direction (third direction) can be absorbed by the spaces between the base members 500. If the base members 500 are arranged in contact with each other in the Y-axis direction, the front faces of the base members 500 aligned in the X-axis direction may not be aligned in the Y-axis direction due to dimensional tolerances of the base members 500, etc. If the front faces of the base members 500 aligned in the X-axis direction are not aligned, the front faces of the electrical boards 100 aligned in the X-axis direction may not be aligned. For this reason, the base members 500 are arranged at intervals in the Y-axis direction. This allows dimensional tolerances of the base members 500 in the Y-axis direction to be absorbed, so that the front faces (end faces in the Y-axis direction) of the base members 500 aligned in the X-axis direction (second direction) can be aligned. By arranging the base members 500 at intervals in the Y-axis direction, multiple electrical boards 100 can be easily installed at predetermined intervals in the Y-axis direction. As a result, even if the installation surface of the electrical board 100 is distorted, uneven, or tilted, or if the dimensional error of the electrical board 100 is large, by installing multiple electrical boards 100 at predetermined intervals in the Y-axis direction, it is possible to prevent problems such as interference between electrical boards 100 lined up in the Y-axis direction. By dividing the base member 500 that fixes multiple electrical boards 100 into multiple parts in the Y-axis direction, the size of each base member 500 can be reduced, making it possible to manufacture the base member 500 inexpensively and also facilitating transportation and installation of the base member 500. As a result, electrical boards 100 lined up in the Y-axis direction can be easily installed, thereby improving work efficiency in the installation work of the electrical boards 100.

[0093] According to the manufacturing method of the energy storage facility 1, the base member 500 has a frame shape, which can reduce the weight of the base member 500 and the amount of material used. The frame shape of the base member 500 creates a space inside the base member 500, which can allow wiring to pass through the space and can improve the heat dissipation of the electrical panels 100, 300.

[0094] According to the manufacturing method of the energy storage facility 1, the electrical panels 100, 300 can be easily fixed on the base member 500 by fixing the electrical panels 100, 300 using the positioning parts of the base member 500. Since the fixing positions of the electrical panels 100, 300 can be adjusted using the positioning parts of the base member 500, the spacing between the electrical panels 100, etc. can be easily fine-tuned.

[0095] According to the energy storage facility 1 of the embodiment of the present invention, multiple base members 500, each having an outer dimension in the X-axis direction (second direction) larger than that of the electrical panels 100, 300, are arranged in contact with each other in the X-axis direction (second direction). The multiple electrical panels 100, 300 are fixed to the multiple base members 500 at predetermined intervals in the X-axis direction (second direction). In this way, even if the installation surface of the electrical panels 100, 300 is distorted, uneven, or tilted, or the dimensional error of the electrical panels 100, 300 is large, installing the multiple electrical panels 100, 300 at predetermined intervals can prevent problems such as interference between the electrical panels 100. This allows the energy storage facility 1 to easily install the electrical panels 100, 300, thereby improving the work efficiency of the installation work of the electrical panels 100, 300. In particular, by fixing the electrical boards 100, 300 to the base member 500, whose outer dimensions in the X-axis direction (second direction) are larger than those of the electrical boards 100, 300, when fixing the electrical boards 100, 300 to the base member 500, the electrical boards 100, 300 can be easily installed at a predetermined interval in the X-axis direction (second direction). By dividing the base member 500 to which the electrical boards 100, 300 are fixed into multiple parts, the size of each base member 500 can be reduced, making it possible to manufacture the base member 500 inexpensively and facilitating transportation and installation of the base member 500. By arranging the multiple base members 500 in contact with each other in the X-axis direction (second direction), it is possible to prevent the intervals between the multiple electrical boards 100, 300 from becoming too large. By installing the multiple electrical boards 100, 300 at intervals, the multiple electrical boards 100, 300 can be installed individually, which also contributes to shortening the construction period. For these reasons, the electricity storage facility 1 can improve the work efficiency in the installation of the electrical panels 100, 300.

[0096] [5. Explanation of Variations] Although the manufacturing method of the energy storage facility 1 and the energy storage facility 1 according to the embodiment of the present invention have been described above, the present invention is not limited to this embodiment. The embodiment disclosed herein is an example in all respects, and the scope of the present invention includes all modifications within the meaning and scope of the claims.

[0097] (Variation 1) In the above embodiment, two electrical panels 100 are fixed side by side on one base member 500 (510 or 520), but only one electrical panel 100 may be placed on one base member 500. Fig. 7 is a plan view showing the configuration of a base member 500 (540) provided in an energy storage facility 2 according to a first modification of the present embodiment, and its positional relationship with the electrical panel 100. Fig. 7 is a view corresponding to a part of Fig. 6.

[0098] As shown in FIG. 7 , the energy storage facility 2 in this modification includes a base member 540 as the base member 500. The base member 540 has a configuration in which the base member 510 in the above embodiment is divided into two in the X-axis direction, or a configuration in which the base member 520 in the above embodiment is divided into two in the Y-axis direction. As a result, only one electrical board 100 is placed on the base member 540. Each base member 540 includes a positioning portion 541 that positions the electrical board 100 on the base member 540. The positioning portion 541 has a configuration similar to the positioning portions 511 and 512 included in the base member 510 in the above embodiment, and therefore a detailed description thereof will be omitted.

[0099] The base member 540 has an outer dimension larger than that of the electrical board 100 in the X-axis direction (second direction). The multiple base members 540 are arranged in contact with each other in the X-axis direction (second direction). Two electrical boards 100 on two base members 540 adjacent to each other in the X-axis direction are fixed with a predetermined distance (distance S6 in FIG. 7) between them in the X-axis direction (second direction). The distance S6 in this modified example is the distance between two electrical boards 100 lined up in the X-axis direction, which is set by contacting two base members 500 (540) lined up in the X-axis direction. The above-mentioned fixing portion and positioning portion 541 determine the distance between the two electrical boards 100 with relatively high precision.

[0100] Two base members 540 aligned in the Y-axis direction are spaced apart in the Y-axis direction. Two electrical boards 100 on two base members 540 adjacent to each other in the Y-axis direction are fixed at a predetermined distance in the Y-axis direction (distance S5 in FIG. 7). The distance S5 in this modification is the distance between two electrical boards 100 aligned in the Y-axis direction when there is a distance between two base members 500 (510) aligned in the Y-axis direction. In this case, the distance between the two electrical boards 100 is not determined accurately, so the dimensional tolerance is set relatively large. The two electrical boards 100 are aligned and fixed on the two base members 540 so that the rear panels 114 (back faces) of the two electrical boards 100 face each other. As a result, all of the multiple electrical boards 100 aligned in the X-axis direction and the Y-axis direction are arranged at predetermined distances in the X-axis direction and the Y-axis direction.

[0101] The spacing S6 in this modified example may be the same size as the spacings S1 to S4 in the above embodiment, or may be a spacing of a different size. The spacing between any two electrical boards 100 lined up in the X-axis direction may be a spacing of a different size from spacing S6. The spacing between any two electrical boards 100 lined up in the Y-axis direction may be a spacing of a different size from spacing S5. The shape of the base member 540 is not particularly limited, but in this modified example, the base member 540 is frame-shaped in a plan view (as viewed from the Z-axis direction). The other configurations of this modified example are the same as those of the above embodiment, so description thereof will be omitted.

[0102] This modification can also achieve the same effects as the above embodiment. In particular, in this modification, by dividing the base member 500 into a plurality of parts, the size of each base member 540 can be reduced, which makes it possible to manufacture the base member 540 at lower cost and makes it easier to transport and install the base member 540.

[0103] (Variation 2) In the above-described embodiment and modified example 1, the base members 500 arranged in the Y-axis direction are arranged at a distance from each other, but they may be arranged in contact with each other. Fig. 8 is a plan view showing the configuration of the base member 500 (550) included in the power storage facility 3 according to modified example 2 of the present embodiment, and its positional relationship with the electrical panel 100. Fig. 8 is a view corresponding to a part of Fig. 6 or Fig. 7.

[0104] As shown in Fig. 8, the power storage equipment 3 in this modification includes a base member 550 as the base member 500. The base member 550 is obtained by extending the base member 540 in the above-described modification 1 inward in the Y-axis direction so that adjacent base members 550 in the Y-axis direction come into contact with each other. Each base member 550 includes a positioning portion 551 that positions the electrical panel 100 on the base member 550. The positioning portion 551 has a configuration similar to the positioning portion 541 included in the base member 540 in the above-described modification 1, and therefore a detailed description thereof will be omitted.

[0105] The base member 550 has larger external dimensions in the X-axis direction and the Y-axis direction than the electrical panel 100. The multiple base members 550 are arranged in contact with each other in the X-axis direction and the Y-axis direction. Two electrical panels 100 on two base members 550 adjacent to each other in the X-axis direction are fixed with a predetermined distance (distance S6 in FIG. 8) in the X-axis direction. The distance S6 in this modification is the same as the distance S6 in the first modification.

[0106] Two electrical boards 100 on two base members 550 adjacent in the Y-axis direction are fixed at a predetermined distance in the Y-axis direction (distance S5a in FIG. 8 ). The distance S5a in this modification is the distance between two electrical boards 100 aligned in the Y-axis direction, set by contacting two base members 500 (550) aligned in the Y-axis direction. The above-mentioned fixing portion determines the distance between the two electrical boards 100 with relatively high precision. The distance S5a in this modification may be different from the distance S5 in the above embodiment or other modifications. The two electrical boards 100 are fixed side by side on the two base members 550 so that the rear panels 114 (back faces) of the two electrical boards 100 face each other. As a result, all of the multiple electrical boards 100 aligned in the X-axis direction and the Y-axis direction are arranged at predetermined distances in the X-axis direction and the Y-axis direction.

[0107] The spacing S6 in this modification may be the same as or different from the spacings S1 to S4 in the above embodiment. The spacing between any two electrical panels 100 aligned in the X-axis direction may be different from the spacing S6. The spacing between any two electrical panels 100 aligned in the Y-axis direction may be different from the spacing S5a. The shape of the base member 550 is not particularly limited, but in this modification, the base member 550 is frame-shaped in a plan view (when viewed from the Z-axis direction).

[0108] As described above, in this modification, the power storage equipment 3 further includes another base member 550 that is arranged in contact with one of the plurality of base members 550 in the Y-axis direction (third direction). The method for manufacturing the power storage equipment 3 further includes arranging one of the plurality of base members 550 and the other base member 550 in contact with each other in the Y-axis direction (third direction). The other configuration of this modification is the same as that of the above-described embodiment, and therefore description thereof will be omitted.

[0109] This modification can also achieve the same effects as the above-described embodiment and modification 1. In particular, in this modification, by arranging the base members 550 in contact with each other in the Y-axis direction (third direction), it is possible to prevent the gap between the electrical panels 100 in the Y-axis direction (third direction) from becoming too large. In this modification, the two base members 510 aligned in the Y-axis direction in the above-described embodiment may be arranged in contact with each other.

[0110] (Variation 3) In the above-described embodiment and modified examples 1 and 2, the base members 500 arranged in the X-axis direction are arranged in contact with each other, but they may also be arranged spaced apart. Fig. 9 is a plan view showing the configuration of a base member 500 (550) included in an energy storage facility 4 according to modified example 3 of the present embodiment, and its positional relationship with the electrical panel 100. Fig. 9 is a view corresponding to Fig. 8.

[0111] As shown in FIG. 9 , in the energy storage facility 4 of this modification, the base members 550 of the second modification are spaced apart in the X-axis direction. As a result, two electrical panels 100 on two adjacent base members 550 in the X-axis direction are fixed at a predetermined distance in the X-axis direction (distance S7 in FIG. 9 ). The distance S7 in this modification is the distance between two electrical panels 100 aligned in the X-axis direction when there is a distance between two base members 500 (550) aligned in the X-axis direction. In this case, the distance between the two electrical panels 100 is not precisely determined, so the dimensional tolerance is set relatively large. The distance S7 in this modification is larger than the distances S1 to S4 in the embodiment described above, but may be the same as or smaller than the distances S1 to S4. The distance between any two electrical panels 100 aligned in the X-axis direction may be different from the distance S7. The other configuration of this modification is similar to that of the second modification, and therefore a description thereof will be omitted.

[0112] Thus, in this modified example, the Y-axis direction is an example of the second direction, and the X-axis direction is an example of the third direction. That is, in this modified example, multiple base members 550 whose outer dimensions in the Y-axis direction (second direction) are larger than the outer dimensions of the electrical panel 100 are arranged in contact with each other in the Y-axis direction (second direction). Multiple electrical panel 100s are fixed to the multiple base members 550 at predetermined intervals in the Y-axis direction (second direction). The base members 500 are arranged at a distance in the X-axis direction (third direction).

[0113] This modification can also achieve the same effects as those of the above-described embodiment and modification 2. In particular, in this modification, by arranging the base members 550 at intervals in the X-axis direction, the dimensional tolerance of the base members 550 in the X-axis direction can be absorbed by the spaces between the base members 550. In this modification, in the effects described in the above-described embodiment, the X-axis direction (second direction) can be rephrased as the Y-axis direction (second direction), and the Y-axis direction (third direction) can be rephrased as the X-axis direction (third direction). In this modification, the four base members 510 in the above-described embodiment may be configured such that two base members 510 aligned in the Y-axis direction are in contact with each other and two base members 510 aligned in the X-axis direction are spaced apart.

[0114] (Variation 4) In the above embodiment, only one base member 520 is arranged, but multiple base members 520 may be arranged. Fig. 10 is a plan view showing the configuration of a base member 500 (520) included in an electricity storage facility 5 according to a fourth modification of the present embodiment, and the positional relationship with the electrical panel 100. Fig. 10 is a view corresponding to a part of Fig. 6 or Fig. 8.

[0115] As shown in FIG. 10 , the power storage equipment 5 of this modification includes a plurality of base members 520 arranged in the X-axis direction as the base member 500. It can also be said that the power storage equipment 5 has a configuration in which two base members 550 arranged in the Y-axis direction, which are included in the power storage equipment 3 of the second modification, are integrated. The plurality of base members 520 are arranged in contact with each other in the X-axis direction. Two electrical boards 100 on two base members 520 adjacent to each other in the X-axis direction are fixed with a predetermined distance (distance S8 in FIG. 10 ) in the X-axis direction. The distance S8 in this modification is the distance between the two electrical boards 100 arranged in the X-axis direction, which is set by bringing the two base members 500 (520) arranged in the X-axis direction into contact with each other. The distance between the two electrical boards 100 is determined with relatively high precision by the fixing portion and the positioning portion 521. The distance S8 in this modification may be the same as or different from the distances S1 to S4 in the above embodiment. The distance between any two electrical panels 100 arranged in the X-axis direction may be different from the distance S8. The other configurations of this modified example are the same as those of the above embodiment, and therefore will not be described.

[0116] This modification can also achieve the same effects as the above embodiment. In particular, in this modification, by arranging base members 520 in the X-axis direction, it is not necessary to place base member 510 as in the above embodiment, and therefore the configuration of power storage equipment 5 can be simplified.

After the plurality of base members 500 are arranged in contact with each other and an electrical panel 100 or the like is installed on the base members 500, gaps may be formed between the plurality of base members 500.

[0120] In the above embodiment, electrical panels 100 are installed on all base members 500, but if the number of electrical panels 100 is odd, for example, electrical panels 100 may not be installed on any of the base members 500. In this case, only one electrical panel 100 may be installed on any of the base members 510 or 520, such as the base member 510 located at a corner. In the case of the above modification 1, any of the base members 540 and electrical panels 100, such as the base member 540 and electrical panel 100 located at a corner, may not be installed.

[0121] In the above embodiment, all of the base members 500 have a frame shape in a plan view, but there are no particular limitations on the shape of the base members 500. Some or all of the base members 500 may have an L-shape, C-shape, U-shape, H-shape, T-shape, etc. in a plan view, or may be a plate-like member.

[0122] In the above embodiment, the positioning portions 511 and 512 of the base member 510 are protrusions (positioning pins) that limit movement of the electrical board 100 in the X-axis direction relative to the base member 510, but this is not limited to this. The positioning portions 511 and 512 may not be protrusions, but may be recesses, or markings such as letters, symbols, or coloring. The positioning portions 511 and 512 may be portions that limit movement of the electrical board 100 in the Y-axis direction relative to the base member 510. The same applies to the positioning portions 521 and 522 of the base member 520 and the positioning portions 531 and 532 of the base member 530.

[0123] In the above embodiment, all of the base members 500 are provided with positioning portions, but some or all of the base members 500 may not be provided with positioning portions.

[0124] In the above embodiment, all of the base members 500 and all of the electrical panels 100 and 300 have the above configuration, but this is not limited to this. Any of the base members 500 may not have the above configuration. Any of the multiple electrical panels 100 and 300 may not have the above configuration.
