Summary of the Invention
Problems to be Solved by the Invention
[0004] In recent years, technologies for adjacent installation of large-scale power storage equipment to solar power plants, factories, etc. have attracted attention. As such power storage equipment, for example, a power storage equipment including a plurality of power storage units, a power collection unit that aggregates the power input and output of the plurality of power storage units, and a control unit that controls the operation of the power storage equipment has been devised.
[0005] As a method for realizing the control unit of the power storage equipment as described above, a configuration in which various control devices are housed in a box-shaped housing can be considered. In such a configuration, since there is a possibility that a voltage is applied to the inner wall surface of the housing, control devices with low withstand voltage need to be housed in the housing via insulating members.
[0006] However, when insulating members are provided for each control device with low withstand voltage, the number of parts increases, and thus it is assumed that a problem of increased manufacturing cost occurs. Patent Document 1 does not disclose a technique capable of solving such a problem.
[0007] This disclosure was made to solve these problems and aims to provide a control unit that can suppress manufacturing costs. [Means for solving the problem]
[0008] The control unit according to this disclosure comprises control equipment for an energy storage system, a housing for housing the control equipment, and a panel on which a plurality of control equipment are arranged on the main surface. The panel is fixed to the inner side surface or inner bottom surface of the housing via an insulating member. [Effects of the Invention]
[0009] This disclosure makes it possible to provide a control unit that can reduce manufacturing costs. [Brief explanation of the drawing]
[0010] [Figure 1] This is a block diagram showing the configuration of the energy storage equipment according to the first embodiment. [Figure 2] This is a schematic perspective view showing the structure of the control unit according to the first embodiment. [Figure 3] This is a flowchart showing a method for manufacturing a control unit according to the first embodiment. [Modes for carrying out the invention]
[0011] <First Embodiment> (Control unit configuration) The first embodiment of this disclosure will be described in detail below with reference to the drawings. First, the configuration of the control unit according to this embodiment will be described in detail.
[0012] Figure 1 is a block diagram showing the configuration of an energy storage system according to the first embodiment. More specifically, Figure 1 is a block diagram showing the configuration of an energy storage system in which the control unit according to this embodiment is introduced.
[0013] The power storage device 1000 is a device adjacent to large facilities such as power plants, substations, factories, etc. The power storage device 1000 is configured to charge the surplus power of the adjacent large facility and discharge the charged power as needed.
[0014] For example, when the adjacent large facility is a power plant, the power storage device 1000 charges the surplus power generation. And when the required power supply amount exceeds the power generation amount of the power plant, the power storage device 1000 discharges the charged power.
[0015] As shown in FIG. 1, the power storage device 1000 according to the present embodiment includes a control unit 1, a power collection unit 2, and a plurality of power storage units 3. In FIG. 1, only one power storage unit 3 is shown, but actually the power storage device 1000 includes two or more power storage units 3.
[0016] The power storage unit 3 is a device configured by housing a power storage module in a casing. The power storage unit 3 is connected to the power collection unit 2. The power storage unit 3 executes charge and discharge based on the control from the control unit 1.
[0017] The power collection unit 2 is a device connected to a plurality of power storage units 3, aggregates the power discharged from the power storage units 3, and outputs it to the outside. Also, when power is supplied from the outside, the power collection unit 2 supplies the supplied power to the plurality of power storage units 3.
[0018] The control unit 1 is a device that controls the operations of the power collection unit 2 and the power storage units 3. The control unit 1 executes, for example, control of the charge and discharge amounts of the power storage units 3, state management of the power collection unit 2 and the power storage units 3, communication with the outside, interruption of power supply in an emergency, etc.
[0019] FIG. 2 is a schematic perspective view showing the structure of the control unit according to the first embodiment. More specifically, FIG. 2 is a schematic perspective view showing a part of the internal structure of the control unit 1. As shown in FIG. 2, the control unit 1 includes a control device 11, a housing 12, a panel 13, an insulating member 14, and a clamp 15.
[0020] The control device 11 is a control device of the power storage facility 1000, and executes the control processing of the above-described power collection unit 2 and power storage unit 3. The control device 11 is disposed on the main surface of the panel 13 described later, and is housed in the housing 12 together with the panel 13.
[0021] In FIG. 2, only the control device 11 disposed on the panel 13 is shown, but the control unit 1 may include control devices disposed at positions other than on the panel 13. For example, the control unit 1 may include a control device disposed on the floor surface of the housing 12. That is, in the control unit 1 according to the present embodiment, it is not necessary to dispose all the control devices on the panel 13, and at least some of the control devices may be disposed on the panel 13.
[0022] The control device 11 disposed on the panel 13 is a control device having low withstand voltage, and may be, for example, at least one of a cutoff device, a power supply device, a communication device, a control board, a noise filter, a leakage detector, a switch, and a terminal block.
[0023] The housing 12 is a structure that houses the control device 11. The housing 12 according to the present embodiment is a box-shaped or hut-shaped structure. The panel 13 is fixed to the inner side surface or the inner bottom surface of the housing 12 via the insulating member 14.
[0024] The panel 13 is a plate-like member on which the control device 11 is disposed on the main surface. The shape of the panel 13 can be appropriately set and is not particularly limited, but in the present embodiment, it is rectangular. The panel 13 is fixed to the inner side surface or the inner bottom surface of the housing 12 via the insulating member 14. The insulating member 14 is, for example, insulating grease, and connects the housing 12 and the panel 13 while electrically insulating them.
[0025] In other words, in the control unit 1 according to this embodiment, the control device 11 is fixed to the housing 12 via the panel 13 and the insulating member 14. With this configuration, the control unit 1 according to this embodiment can be fixed to the housing 12 while electrically insulating the control devices 11 without providing insulating members for each of the control devices 11. In other words, the control unit 1 according to this embodiment can fix the control device 11 to the housing 12 while suppressing the number of parts, and as a result, manufacturing costs are reduced.
[0026] Furthermore, the panel 13 according to this embodiment includes a clamp 15 for bundling wiring housed inside the housing 12. The clamp 15 may, for example, grip wiring extending from a control device 11 located on the panel 13.
[0027] (Manufacturing method for control units) Next, the manufacturing method of the control unit according to this embodiment will be described in detail. Figure X is a flowchart showing the manufacturing method of the control unit according to the first embodiment.
[0028] In the manufacturing method of the control unit according to this embodiment, first, the control device 11 of the energy storage equipment 1000 is fixed onto the panel 13 (step ST1). In step ST1, the control device 11 may be fixed to the panel 13 by mechanical fastening, such as screw fastening. Next, the panel 13 on which the control equipment 11 is placed is fixed to the inner side or inner bottom surface of the housing 12 via an insulating member 14 (step ST2).
[0029] The control unit according to this embodiment can be manufactured through the process described above. In the manufacturing method of the control unit according to this embodiment, process ST1 and process ST2 may be performed at different locations. For example, in the manufacturing method of the control unit according to this embodiment, process ST1 may be performed at the manufacturing plant and process ST2 may be performed at the installation site of the energy storage equipment 1000. With this configuration, the manufacturing method of the control unit according to this embodiment can reduce the amount of work that needs to be performed at the installation site.
[0030] As described above, in the control unit 1 according to this embodiment, the control equipment 11 is placed on the main surface of the panel 13, and the panel 13 is fixed to the housing 12 via an insulating member 14. With this configuration, the control unit 1 according to this embodiment can fix the control devices 11 to the housing 12 without providing insulating members for each of the control devices 11. As a result, the control unit 1 according to this embodiment can reduce manufacturing costs.
[0031] Although the present invention has been described above in reference to the embodiments described above, the present invention is not limited to the configuration of the embodiments described above, and of course includes various modifications, alterations, and combinations that can be made by a person skilled in the art within the scope of the claims of the present patent application.
