[0003] [Patent Document 1] Patent Publication No. 2021-68670 Summary of the Invention [Problem to be solved by the invention]

[0004] From the viewpoint of user convenience, it is desirable to place the main unit in various locations, including outdoors. However, depending on the location and time of day of installation of the main unit, there is a concern that the operating noise of each fan and air conditioner may become a noise.

[0005] An object of the present invention is to solve the above-mentioned problems. [Means for solving the problem]

[0006] A first aspect of the present invention is a temperature control device that adjusts the temperature of a temperature control target, the temperature control device having a control unit that controls the temperature control device, and the control unit controls the temperature control device based on an upper limit value of the noise volume of a main device in which the temperature control device is installed and which is the temperature control target, which is dissipated from the main device to the outside of the main device, or an upper limit value of the operating amount of the temperature control device or the main device corresponding to the upper limit value of the noise volume of the main device.

[0007] A second aspect of the present invention is an electric power device in which the temperature adjustment device is installed and the temperature is adjusted by the temperature adjustment device.

[0008] A third aspect of the present invention is a control method for a temperature control device that adjusts the temperature of a temperature control target, the control method including a first step of setting an upper limit value for the noise volume of a main device that is dissipated from a main device in which the temperature control device is installed to the outside of the main device, or an upper limit value for the operating volume of the temperature control device or the main device corresponding to the upper limit value of the noise volume of the main device, and a second step of controlling the temperature control device based on the upper limit value of the noise volume of the main device or the upper limit value of the operating volume of the temperature control device or the main device.

[0009] A fourth aspect of the present invention is a program for causing a computer to execute the above-mentioned control method.

[0011] According to the present invention, an upper limit value for the noise volume of the main unit that is dissipated from the main unit in which the temperature control device is installed to the outside of the main unit, or an upper limit value for the operation volume of the temperature control device or the main unit corresponding to the upper limit value for the noise volume of the main unit is set. As a result, even if the noise suppression method for each part of the main unit is not known, the noise volume of the main unit can be suppressed to below the upper limit value of the noise volume by controlling the temperature control device based on the upper limit value of the noise volume of the main unit or the upper limit value for the operation volume of the temperature control device or the main unit. As a result, the noise of the main unit can be easily and reliably suppressed regardless of the installation location and time of day of the main unit. [Brief description of the drawings]

[Diagram 3] FIG. 3 is a circuit diagram of a power device including a temperature regulator. [Figure 4] FIG. 4 is a diagram showing an example of the table of FIG. [Diagram 5] FIG. 5 is a flowchart showing a method for controlling the temperature adjustment device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] FIG. 1 is a front view of a power device 10 (main device) according to this embodiment.

[0014] The power device 10 is installed, for example, outdoors. The power device 10 has a housing 22. The housing 22 is rectangular in shape. The housing 22 has a plurality of slots 28. Each of the plurality of slots 28 opens to a front face 30 of the housing 22. A battery 32 (power storage unit) is detachably attached to the plurality of slots 28. A user can attach and detach the battery 32 to and from the plurality of slots 28.

[0015] It is sufficient that at least one battery 32 is attached to the housing 22. When the housing 22 is capable of attaching multiple batteries 32, it is sufficient that at least one of the multiple batteries 32 is detachable from the housing 22. It is more preferable that the battery 32 is detachable from the housing 22 without using a separate work tool or the like. That is, the battery 32 is configured to be detachable from the housing 22 without using a work tool or the like. In addition, "attaching to and detaching from the housing 22 (power device 10)" includes a case where the battery 32 is attached to the housing 22 and a case where the battery 32 is detached from the housing 22. In the following description, a case where multiple batteries 32 are detachable from the housing 22 will be described.

[0016] Therefore, the battery 32 is a mobile battery that is detachable from the housing 22. The shape of the battery 32 is a substantially rectangular parallelepiped. The battery 32 is a mobile battery that is chargeable and dischargeable. The battery 32 is preferably, for example, a detachable lithium-ion battery pack.

[0017] An operation panel 34 is provided on the front surface 30 of the housing 22 above the multiple slots 28. The operation panel 34 is, for example, a touch panel. The operation panel 34 can display various information such as the remaining capacity of the battery 32. A user can operate the operation panel 34 to input various instructions.

[0018] An air intake 35 is provided on the front surface 30 of the housing 22 above the multiple slots 28. The air intake 35 takes in outside air into the housing 22.

[0019] The housing 22 is provided with four slots 28 in the vertical direction. In addition, the housing 22 is provided with three slots 28 in the horizontal direction. Therefore, the housing 22 is provided with a total of 12 slots 28. Note that in this embodiment, batteries 32 do not necessarily need to be installed in all of the 12 slots 28. FIG. 1 illustrates a case in which batteries 32 are installed in all of the 12 slots 28.

[0020] FIG. 2 is a cross-sectional view of the housing 22.

[0021] The interior of the housing 22 is divided into two chambers by a horizontally extending partition plate 36. Within the interior of the housing 22, the chamber above the partition plate 36 is a first chamber 38 (space). The chamber below the partition plate 36 is a second chamber 40. An opening / closing door 46 is provided at the rear of the housing 22. When a user opens the opening / closing door 46, the first chamber 38 and the second chamber 40 are exposed to the outside. An exhaust port 47 is formed in a portion of the opening / closing door 46 facing the first chamber 38.

[0022] An inverter 50 (electrically operated unit), a DC / DC converter 52 (electrically operated unit), a control box 54, and a fan 55 (air generating unit, first temperature adjustment unit) are arranged in the first chamber 38. When the fan 55 is driven, an airflow is generated inside the first chamber 38. That is, air (outside air) is taken into the first chamber 38 from the outside of the housing 22 through the air intake 35. The taken-in air flows from the front to the rear inside the first chamber 38, as shown by the arrows. The air flowing rearward is exhausted from the fan 55 to the outside of the housing 22 through the exhaust port 47.

[0023] A plurality of slots 28 are arranged in the second chamber 40. Each of the plurality of slots 28 extends from the front surface 30 of the housing 22 toward the rear, inclining obliquely downward. A fan 56 (air generating section, second temperature control section), a DC / DC converter 58, and a slot side board 60 are arranged at the rear of each of the plurality of slots 28. The fan 56 generates an airflow inside the slot 28, thereby promoting the flow of air inside and outside the slot 28. When the fan 56 is driven, air is taken into the slot 28 through the fan 56, as shown by the arrow. The taken-in air flows forward from the rear of the slot 28. The air flowing forward is exhausted to the outside of the housing 22 from the opening of the slot 28.

[0024] The multiple DC / DC converters 58 may be arranged together in the first chamber 38. In this case, the multiple DC / DC converters 58 are arranged, for example, near the intake port 35 in the first chamber 38. In addition, both the multiple DC / DC converters 58 and the multiple slot-side boards 60 may be arranged in the first chamber 38.

[0025] A frame 62 is disposed between the partition plate 36 and the bottom plate 44 of the housing 22. The frame 62 extends in the vertical direction. The frame 62 fixes the plurality of slots 28 inside the second chamber 40.

[0026] A cooler 57 (heat exchange unit) is provided in a portion of the opening and closing door 46 facing the second chamber 40. The cooler 57 has a case 59, two fans 61 and 63, and a heat exchanger 64.

[0027] The case 59 is provided so as to sandwich the opening / closing door 46. The interior of the case 59 is divided into two internal spaces (an internal space 51 on the second chamber 40 side and an internal space 53 on the outside of the housing 22) by the opening / closing door 46. Two fans 61, 63 and a heat exchanger 64 are housed inside the case 59. The heat exchanger 64 is attached to the opening / closing door 46. The heat exchanger 64 extends in the vertical direction. The fan 61 is disposed in the internal space 51 on the second chamber 40 side of the case 59. The fan 61 is disposed below the heat exchanger 64. The fan 63 is disposed in the internal space 53 on the outside of the housing 22 of the case 59. The fan 63 is disposed above the heat exchanger 64.

[0028] An intake port 65 and an exhaust port 67 are formed in the portion of the case 59 that corresponds to the second chamber 40. The intake port 65 and the exhaust port 67 are formed at a distance in the vertical direction. The intake port 65 is formed in the case 59 so as to face the upper portion of the heat exchanger 64. The exhaust port 67 is formed in the case 59 so as to face the fan 61.

[0029] An air intake port 69 and an exhaust port 71 are formed in a portion of the case 59 that is outside the housing 22. The air intake port 69 and the exhaust port 71 are formed with a gap between them in the vertical direction. The air intake port 69 is formed in the case 59 so as to face the lower part of the heat exchanger 64. The exhaust port 71 is formed in the case 59 so as to face the fan 63.

[0030] When the fan 61 is driven, air in the second chamber 40 is drawn into the internal space 51 through the air intake 65. The air drawn into the internal space 51 flows downward along the heat exchanger 64 as shown by the arrows. The air that flows downward is exhausted to the second chamber 40 through the air exhaust 67.

[0031] When the fan 63 is driven, air outside the housing 22 (outside air) is taken into the internal space 53 through the air intake 69. The air taken into the internal space 53 flows upward along the heat exchanger 64 as shown by the arrow. The air flowing upward is exhausted to the outside of the case 59 through the exhaust port 71.

[0032] The heat exchanger 64 includes a compressor (not shown). The heat exchanger 64 exchanges heat between the air flowing through the internal space 51 (air taken in from the second chamber 40) and the air flowing through the internal space 53 (outside air). In the second chamber 40, the batteries 32, the DC / DC converters 58, and the slot-side boards 60 operate to generate heat, so that the air in the second chamber 40 becomes relatively hot. The heat exchanger 64 absorbs heat from the air taken in from the second chamber 40 to the internal space 51. The heat exchanger 64 transfers the absorbed heat to the air (outside air) flowing through the internal space 53. This cools the air flowing through the internal space 51. The cooled air is exhausted to the second chamber 40 through the exhaust port 67, so that the temperature in the second chamber 40 is adjusted.

[0033] 3 is a circuit configuration diagram of the power device 10. The power device 10 includes an inverter 50, a DC / DC converter 52, a control box 54, an operation panel 34, a speaker 66, a plurality of slots 28, and a temperature sensor 80. As described above, each of the plurality of slots 28 is provided with a fan 56, a DC / DC converter 58, and a slot-side board 60. The control box 54 includes a housing control board 68 (control unit) and a communication unit 74. The housing control board 68 includes a memory 76 (storage medium). The memory 76 stores a table 78, which will be described later.

[0034] The inverter 50 is electrically connected to the outside of the housing 22 (for example, an external power system) via an external connection unit 81 such as a connector. A power supply unit 83 for supplying power to the cooler 57 is connected to the inverter 50. The power supply unit 83 drives the cooler 57 (fans 61, 63, heat exchanger 64) by supplying power to the cooler 57. The multiple DC / DC converters 52, 58 and the power supply unit 83 are electrically connected in parallel to the inverter 50. The portion from the external connection unit 81 to the multiple DC / DC converters 52, 58 and the cooler 57 is a relatively high-voltage circuit portion (high-voltage circuit 82). In FIG. 3, the wiring of the high-voltage circuit 82 is shown by a thick line.

[0035] In the high voltage circuit 82, AC power flows through a portion from the external connection unit 81 to the inverter 50. That is, when power (external power) is supplied from outside the housing 22, relatively high voltage AC power is supplied to the inverter 50 via the external connection unit 81. The inverter 50 converts the AC power into relatively high voltage DC power. The converted DC power is supplied to the multiple DC / DC converters 52, 58 and the power supply unit 83. The multiple DC / DC converters 52, 58 convert the relatively high voltage DC voltage into a low voltage DC voltage.

[0036] The battery 32 has a connector 84. The slot 28 has a connector 86 (internal connection portion) that can be fitted into the connector 84 of the battery 32. When the battery 32 is attached to the slot 28, the connector 84 of the battery 32 and the connector 86 of the slot 28 are connected. When the battery 32 is attached to each of the multiple slots 28, each of the multiple DC / DC converters 58 can output the converted low-voltage direct current voltage to the battery 32. As a result, the battery 32 receives a supply of external power and stores (charges) electricity.

[0037] When power is output from the housing 22 to the outside, the DC / DC converter 58 provided in each of the multiple slots 28 converts the DC voltage of the battery 32 (battery voltage) into a relatively high DC voltage. The inverter 50 converts the DC power supplied from the multiple DC / DC converters 58 into AC power. The converted AC power is output to the outside via the external connection unit 81.

[0038] The DC / DC converter 52 converts a relatively high DC voltage into a low DC voltage. The DC / DC converter 52 supplies the converted low DC voltage to the multiple slot side boards 60 and the control box 54. Each of the multiple slot side boards 60 is driven by receiving the voltage supplied from the DC / DC converter 52.

[0039] The sections from the multiple DC / DC converters 58 to the battery 32 and the sections from the DC / DC converter 52 to the control box 54, the multiple slot-side boards 60, and the multiple fans 56 constitute a low-voltage circuit 88. The low-voltage circuit 88 is a relatively low-voltage circuit portion inside the housing 22. Note that in FIG. 3, the wiring of the low-voltage circuit 88 is shown by thin lines.

[0040] In the following description, the power device 10 is a charger that charges the battery 32 with power. In this embodiment, the power device 10 can function as a power feeder that outputs the power of the battery 32 to the outside.

[0041] In the control box 54 , the housing control board 68 is driven by a DC voltage supplied from the DC / DC converter 52 .

[0042] The housing control board 68 is an ECU (electronic control unit) mounted on the housing 22. The housing control board 68 is a computer that may include a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). In other words, the housing control board 68 may be composed of processing circuitry. The housing control board 68 realizes various functions by reading and executing programs stored in the memory 76.

[0043] At least a part of the housing control board 68 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). At least a part of the housing control board 68 may be configured by an electronic circuit including discrete devices.

[0044] The memory 76 may be composed of a volatile memory (not shown) and a non-volatile memory (not shown). The volatile memory may be, for example, a random access memory (RAM). The volatile memory is used as a working memory of the processor, and temporarily stores data and the like required for processing or calculation. The non-volatile memory may be, for example, a read only memory (ROM) or a flash memory. The non-volatile memory is used as a storage memory, and stores programs, tables, maps, and the like. At least a part of the memory 76 may be provided in the processor, integrated circuit, and the like described above.

[0045] The housing control board 68 controls each unit arranged inside the housing 22. Specifically, the housing control board 68 transmits and receives signals to the multiple slot side boards 60. The housing control board 68 supplies control signals to the inverter 50, the DC / DC converter 52, the fan 55, the multiple slot side boards 60, and the power supply unit 83. The housing control board 68 also acquires the detection result of the temperature sensor 80. The housing control board 68 can transmit and receive signals or information to and from the outside of the housing 22 via the communication unit 74. The housing control board 68 can output sound to the outside of the housing 22 via the speaker 66. The housing control board 68 receives the result of an operation of the operation panel 34 by the user.

[0046] Each of the multiple slot-side boards 60 controls the DC / DC converter 58 and the fan 56 based on a control signal from the housing control board 68. When the fan 56 is driven, an airflow is generated inside the slot 28, so that the temperature of the battery 32 attached to the slot 28 can be adjusted to a desired temperature.

[0047] Further, each of the multiple slot-side boards 60 acquires information about the battery 32 from the battery 32. The slot-side board 60 outputs the acquired information about the battery 32 to the housing control board 68. The housing control board 68 can store the input information about the battery 32 in the memory 76.

[0048] The fan 55 is driven based on a control signal from the housing control board 68 to circulate air inside the first chamber 38. This allows the temperature inside the first chamber 38 to be adjusted.

[0049] The power supply unit 83 supplies power to the cooler 57 based on a control signal from the housing control board 68. The cooler 57 is driven by receiving the power supply from the power supply unit 83. The temperature in the second chamber 40 is adjusted by driving the cooler 57.

[0050] The temperature sensor 80 sequentially detects the temperature of the inverter 50 or the DC / DC converter 52 arranged in the first chamber 38. Alternatively, the temperature sensor 80 sequentially detects the temperature of the first chamber 38. For this reason, the temperature sensor 80 is arranged, for example, near the air intake 35 in the first chamber 38 (see FIG. 2). The temperature sensor 80 sequentially outputs the detection results to the housing control board 68.

[0051] It is sufficient that the temperature sensor 80 is able to detect the temperature of the inverter 50 or the DC / DC converter 52, or the temperature of the first chamber 38. Therefore, the temperature sensor 80 may be installed inside the first chamber 38. Alternatively, the temperature sensor 80 may be disposed at a position (near the) air intake 35 on the front surface 30 of the housing 22. In this case, the temperature sensor 80 detects the temperature outside the housing 22 (outside air temperature). However, since outside air is introduced into the first chamber 38 via the air intake 35, it is also possible to substitute the outside air temperature detected by the temperature sensor 80 for the temperature of the first chamber 38.

[0052] The fan 55, the multiple fans 56, the cooler 57, the multiple slot side boards 60, the housing control board 68, the temperature sensor 80, and the power supply unit 83 constitute a temperature adjustment device 90 for adjusting the temperature of the power device 10 (the temperature inside the housing 22). That is, the power device 10 is provided with the temperature adjustment device 90.

[0053] As shown in Fig. 1, the power device 10 is installed at an arbitrary installation location. The arbitrary installation location is, for example, outdoors. From the viewpoint of user convenience, it is desirable to place the power device 10 in various locations including outdoors. However, depending on the location where the power device 10 is installed (hereinafter also referred to as the installation location of the power device 10) and the time of day, the operating sounds of the power device 10 and the temperature adjustment device 90 may become noise.

[0054] In the electric power device 10, components that can be noise sources are the fan 55, the multiple fans 56, and the cooler 57. That is, when the fan 55 is driven, the operating sound of the fan 55 becomes noise that is radiated outside the electric power device 10. Also, when the multiple fans 56 are driven, the operating sounds of the multiple fans 56 become noise that is radiated outside the electric power device 10. Furthermore, when the cooler 57 is operating, the operating sounds of the fans 61 and 63 of the cooler 57 and the operating sound of the compressor that constitutes the heat exchanger 64 become noise that is radiated outside the electric power device 10.

[0055] Furthermore, the inverter 50, the DC / DC converter 52, the multiple DC / DC converters 58, and the power supply unit 83 each have a self-cooling fan (not shown). When these fans are driven, they generate operating noise. If these operating noises are dissipated to the outside of the power device 10, they become noise. Therefore, these fans also become noise sources. However, these fans cannot be directly controlled by the housing control board 68. The housing control board 68 controls the inverter 50, the DC / DC converter 52, the multiple DC / DC converters 58, and the power supply unit 83, thereby controlling the driving of each fan.

[0056] Depending on the location where the power device 10 is installed (the point where the power device 10 is installed, the area where the power device 10 is installed), laws and regulations may prescribe an upper limit for noise (noise regulation value). Furthermore, laws and regulations may prescribe noise regulation values ​​according to the time or time period during which various noise sources including the power device 10 are in operation. Therefore, it is preferable to appropriately set the operation of the power device 10 taking into account the noise regulation value. Even if the power device 10 is not subject to laws and regulations, it is preferable to appropriately set the operation of the power device 10 taking into account the environment or situation of the location where the power device 10 is installed.

[0057] In this embodiment, a table 78 is stored in the memory 76. The table 78 stores a target value (upper noise limit value) of the upper limit of the noise amount of the power device 10 corresponding to the noise regulation value, and upper limits of the operation amounts of the fan 55, the multiple fans 56, and the cooler 57 according to the upper noise limit value.

[0058] 4 is a diagram showing the specific contents of table 78. Five types of upper noise limit values ​​(65 dB or more, 60 dB, 55 dB, 50 dB, and 45 dB) are set in table 78. The upper noise limit value may be any noise value that is equal to or lower than the noise regulation value. Therefore, the noise regulation value may be set as the upper noise limit value.

[0059] Table 78 defines upper limits for the operation rates of fan 55, multiple fans 56, and cooler 57 for each upper noise limit value. As shown in Fig. 4, in table 78, the lower the upper noise limit value, the lower the upper limit values ​​for the operation rates of fan 55, multiple fans 56, and cooler 57 are set (the upper limit values ​​are restricted).

[0060] Specifically, for each of the multiple fans 56, an upper limit of the operation amount corresponding to the upper noise limit value is set as a target duty value. When the upper noise limit value is 65 dB or more and 60 dB, the target duty value is set to 100% for each of the multiple fans 56. When the upper noise limit value is 55 dB or less (55 dB, 50 dB, and 45 dB or less), the target duty value is set to 60% for each of the multiple fans 56. In other words, if the upper noise limit value is large, a relatively large noise is allowed, so the duty of each of the multiple fans 56 may be large. If the upper noise limit value is small, it is necessary to reduce noise, so the duty of each of the multiple fans 56 must be reduced.

[0061] For the cooler 57, the upper limit of the operation amount according to the upper noise limit value is determined by turning the cooler 57 on (duty: 100%) or off (duty: 0%). When the upper noise limit value is 65 dB or more, 60 dB, and 55 dB, the cooler 57 is turned on. When the upper noise limit value is 50 dB or less (50 dB or less and 45 dB or less), the cooler 57 is turned off. In other words, if the upper noise limit value is large, a relatively large noise is tolerated, so the cooler 57 may be turned on. If the upper noise limit value is small, the noise needs to be reduced, so the cooler 57 is turned off.

[0062] The chargeable battery number is the number of batteries 32 that can be charged in the power device 10. That is, the chargeable battery number is the number of batteries 32 to be charged among the multiple batteries 32 installed in the multiple slots 28. Therefore, when a fully charged battery 32 is installed in a slot 28, the battery 32 is not counted as one of the chargeable batteries.

[0063] When charging the battery 32 installed in the slot 28, the DC / DC converter 58 operates, and the fan built into the DC / DC converter 58 becomes a noise source. Furthermore, when the battery 32 installed in the slot 28 is charged, the battery 32 generates heat due to charging. The fan 56 provided in the slot 28 cools the battery 32 by blowing air into the slot 28. Therefore, the fan 56 also becomes a noise source.

[0064] In particular, when multiple DC / DC converters 58 are arranged in the first chamber 38, the operating noise of the fans of the DC / DC converters 58 is dissipated to the outside through the intake port 35 and the exhaust port 47, becoming noise. In this case, the noise of the fans of the multiple DC / DC converters 58 is relatively larger than the noise of the multiple fans 56 and cannot be ignored.

[0065] Therefore, the number of chargeable batteries is the number of DC / DC converters 58 or the number of fans 56 corresponding to the batteries 32 to be charged. Therefore, the number of chargeable batteries is the number of DC / DC converters 58 that operate when charging the batteries 32. Alternatively, the number of chargeable batteries is the number of fans 56 that operate when charging the batteries 32.

[0066] It should be noted that the DC / DC converter 58 and fan 56 of the slot 28 in which a fully charged battery 32 is installed are not driven because the battery 32 is fully charged. Also, the DC / DC converter 58 and fan 56 of the slot 28 in which no battery 32 is installed do not need to be driven because no battery 32 is installed in the slot 28. Therefore, these DC / DC converters 58 and fans 56 are not the DC / DC converters 58 and fans 56 corresponding to the batteries 32 counted in the number of chargeable batteries.

[0067] In table 78, the number of chargeable batteries is set to a predetermined number of upper limits according to the noise upper limit value. When the noise upper limit value is 65 dB or more, 60 dB, 55 dB, and 50 dB, the number of chargeable batteries is set to 12. When the noise upper limit value is 45 dB or less, the number of chargeable batteries is set to 6. In other words, if the noise upper limit value is large, relatively large noises are tolerated for the multiple DC / DC converters 58 and the multiple fans 56, so the number of chargeable batteries may be large. If the noise upper limit value is small, the noises of the multiple DC / DC converters 58 and the multiple fans 56 need to be reduced, so the number of chargeable batteries is reduced.

[0068] For the fan 55, an upper limit of the operation amount according to the upper noise limit value is set by a target duty value. If the upper noise limit value is large, a relatively large noise is tolerated, so the target duty value of the fan 55 is set large. If the upper noise limit value is small, noise needs to be reduced, so the target duty value of the fan 55 is set small.

[0069] As for the fan 55, the target value of the duty, which is the upper limit of the operation amount according to the noise upper limit value, is changed according to the temperature of the inverter 50 or the DC / DC converter 52 arranged in the first chamber 38, or the temperature of the first chamber 38. Specifically, the higher the temperature, the lower the target value of the duty of the fan 55 is set (the target value is limited). That is, as described above, each of the inverter 50, the DC / DC converter 52, and the power supply unit 83 has a built-in fan. The housing control board 68 can control each fan independently by controlling the inverter 50, the DC / DC converter 52, and the power supply unit 83. In this case, when the above temperature becomes relatively high, the rotation speed (noise value) of each fan increases. Therefore, unless the target value of the duty of the fan 55 is reduced, the noise cannot be suppressed below the noise upper limit value.

[0070] The housing control board 68 acquires information such as the location where the power device 10 is installed and the current time from the outside via the communication unit 74. In addition, the housing control board 68 acquires the temperature of the inverter 50 or the DC / DC converter 52, or the temperature of the first chamber 38 from the temperature sensor 80.

[0071] The housing control board 68 sets a noise upper limit value based on the acquired information such as the installation location of the power device 10 and the current time. The housing control board 68 references the table 78 and sets target values ​​of the duties of the multiple fans 56 according to the noise upper limit value. The housing control board 68 also references the table 78 and determines whether to turn on or off the cooler 57 according to the noise upper limit value. The housing control board 68 also references the table 78 and sets the number of batteries that can be charged according to the noise upper limit value. The housing control board 68 also references the table 78 and sets a target value of the duty of the fan 55 according to the noise upper limit value and the temperature detected by the temperature sensor 80.

[0072] The housing control board 68 controls the fan 55, the multiple fans 56, and the power supply unit 83 (cooler 57) in accordance with the determined (set) contents.

[0073] The electric power device 10 according to this embodiment is configured as described above. Next, the operation of the electric power device 10 will be described with reference to the flowchart in Fig. 5. Here, the case where the housing control board 68 (see Fig. 3) controls the temperature adjustment device 90 based on the upper noise limit value, etc. will be mainly described.

[0074] In step S1, the housing control board 68 acquires information such as the installation location of the power device 10 and the current time from the outside via the communication unit 74. The housing control board 68 also acquires the detection result of the temperature sensor 80 (for example, the temperature of the first chamber 38).

[0075] In step S2 (first step), the housing control board 68 sets an upper noise limit value based on the information such as the installation location of the power device 10 and the current time acquired in step S1.

[0076] In step S3 (first step), the housing control board 68 sets target values ​​for the duties of the multiple fans 56 according to the upper noise limit value with reference to the table 78. The housing control board 68 also sets target values ​​for the duties of the fans 55 according to the upper noise limit value and the temperature with reference to the table 78.

[0077] In step S4 (first step), the housing control board 68 refers to the table 78 and determines whether to turn on or off the cooler according to the upper noise limit value.

[0078] In step S5 (first step), the housing control board 68 refers to the table 78 and sets the number of chargeable batteries according to the upper noise limit value.

[0079] In step S6 (second step), the housing control board 68 controls the fan 55, the multiple fans 56, and the power supply unit 83 (cooler 57) in accordance with the contents determined or set in steps S3 to S5.

[0080] In step S7, the housing control board 68 determines whether or not to repeat the processes of steps S1 to S6.

[0081] When controlling the temperature adjustment device 90 based on the upper noise limit value or the like (step S7: YES), the housing control board 68 returns to step S1 and repeats steps S1 to S6.

[0082] When the operation of the power device 10 including the temperature adjustment device 90 is to be stopped (step S7: NO), the housing control board 68 proceeds to step S8. In step S8, the housing control board 68 stops the operation of the power device 10 including the temperature adjustment device 90. Specifically, the housing control board 68 stops the operation of the fan 55, the multiple fans 56, and the power supply unit 83, thereby stopping the operation of the temperature adjustment device 90. In addition, the housing control board 68 stops the operation of the inverter 50, the DC / DC converter 52, and the multiple DC / DC converters 58, thereby stopping the operation of the power device 10.

[0083] In this embodiment, the information on the point where the electric power device 10 is installed or the place where the electric power device 10 is installed may be input by operating the operation panel 34 when the electric power device 10 is installed. Alternatively, the information may be acquired from outside the electric power device 10 via the communication unit 74. Furthermore, the electric power device 10 may be equipped with a location information acquisition device such as a GPS, and the electric power device 10 itself may acquire information on the point where the electric power device 10 is installed or the place where the electric power device 10 is installed. In this case, the electric power device 10 automatically acquires the information, which saves the user time. Furthermore, the noise upper limit value may be determined by an external computer based on the information on the installation place of the electric power device 10 and the current time, and the determined noise upper limit value may be acquired via the communication unit 74.

[0084] In addition, in the present embodiment, the case where the power device 10 is a charger has been described. Even in the case where the power device 10 is a power feeder, the above description is applicable.

[0085] This embodiment has the following advantages.

[0086] 2 to 5, an upper limit value (upper noise limit value) of the amount of noise of the power device 10 dissipated from the power device 10 (main device) in which the temperature adjustment device 90 is installed to the outside of the power device 10, or an upper limit value of the operation amount of the temperature adjustment device 90 or the power device 10 corresponding to the upper noise limit value is set. As a result, even if the noise suppression method for each part of the power device 10 is not known, the noise amount of the power device 10 can be suppressed to or below the upper noise limit value by controlling the temperature adjustment device 90 based on the upper noise limit value or the upper limit value of the operation amount of the temperature adjustment device 90 or the power device 10. As a result, the noise of the power device 10 can be easily and reliably suppressed regardless of the installation location and time of the power device 10.

[0087] The noise upper limit is determined based on the location or area where the power device 10 is installed. This allows the noise regulation value for that location or area, as determined by laws and regulations, to be determined as the noise upper limit. As a result, the noise of the power device 10 can be appropriately suppressed.

[0088] The upper noise limit value is determined based on the time or time period when the temperature adjustment device 90 operates. This allows the noise regulation value for that time or time period, as determined by laws and regulations, to be set as the upper noise limit value. As a result, the noise of the power device 10 can be appropriately suppressed. In addition, the upper noise limit value can be changed as appropriate for environments in which noise regulation values ​​differ depending on the time or time period, making it easy to use.

[0089] 2 and 3, fan 55 and multiple fans 56 (air-generating section) promote the flow of air inside and outside housing 22. As a result, when battery 32 (power storage section), inverter 50, and DC / DC converter 52 (electrically operating section) housed inside housing 22 are operating and generating heat, the temperature inside housing 22 including battery 32, inverter 50, and DC / DC converter 52 can be appropriately adjusted.

[0090] 4, the upper limit of the operation amount of the temperature adjustment device 90 is the target value (upper limit airflow rate) of the duty of the fans 55, 56. That is, when the fans 55, 56 are operated, the operating sound of the fans 55, 56 becomes noise that is dissipated to the outside from the power device 10. Therefore, by controlling the temperature adjustment device 90 based on the target value (upper limit airflow rate) of the duty of the fans 55, 56, it is possible to suppress the noise of the power device 10 while regulating the temperature inside the housing 22.

[0091] As shown in FIGS. 2 and 3, the temperature adjustment device 90 includes a cooler 57 (heat exchange unit), so that the temperature inside the housing 22 can be adjusted easily and effectively.

[0092] 4, the upper limit of the operation amount of the temperature adjustment device 90 is the on / off (upper limit heat exchange amount) of the cooler 57. That is, when the cooler 57 operates, the operating sound of the cooler 57 becomes noise that is dissipated to the outside from the power device 10. Therefore, by controlling the temperature adjustment device 90 based on whether the cooler 57 is on or off, it is possible to suppress the noise of the power device 10 while adjusting the temperature inside the housing 22.

[0093] As shown in FIGS. 2 and 3, the temperature adjustment device 90 is installed in the power device 10, so that the temperatures of the battery 32, the inverter 50, and the DC / DC converter 52 can be appropriately adjusted.

[0094] 2 and 3, a fan 55 (first temperature adjustment unit) adjusts the temperatures of the inverter 50 and the DC / DC converter 52, and multiple fans 56 (second temperature adjustment unit) adjust the temperatures of the multiple batteries 32. This makes it possible to appropriately and efficiently adjust the temperature of the power device 10 including the battery 32, the inverter 50, and the DC / DC converter 52.

[0095] 2 to 4, the target value (upper limit temperature adjustment amount) of the duty of the fan 55 is changed based on the temperatures of the inverter 50 and the DC / DC converter 52, or the temperature of the first chamber 38 (space) in which the inverter 50 and the DC / DC converter 52 are arranged. That is, when the fan 55 operates, the operating sound of the fan 55 becomes noise that is dissipated from the power device 10 to the outside. Therefore, by controlling the temperature adjustment device 90 based on the changed target value of the duty, it is possible to suppress the noise of the power device 10 while adjusting the temperatures of the inverter 50 and the DC / DC converter 52, or the temperature of the first chamber 38.

[0096] 2 to 4, the upper limit of the operation amount of temperature adjustment device 90 is the target value of the duty of each of fans 55, 56. Thus, by controlling each of fans 55, 56 based on the target value, it is possible to precisely adjust the temperatures of battery 32, inverter 50, and DC / DC converter 52.

[0097] 4, when the upper noise limit value of the power device 10 is equal to or lower than the first noise threshold value, the operation of the fan 55 is restricted. Thus, by setting the first noise threshold value to the upper noise limit value, it is possible to reduce the noise level of the power device 10 to equal to or lower than the upper noise limit value.

[0098] When the noise upper limit value of the power device 10 is equal to or lower than the second noise threshold value, the operation of the fan 56 is restricted. Thus, by setting the second noise threshold value to the noise upper limit value, it is possible to reduce the noise level of the power device 10 to equal to or lower than the noise upper limit value.

[0099] Noise from the power device 10 upper limit When the value is equal to or less than the third noise threshold, only the fan 56 corresponding to the battery 32 capable of inputting and outputting power is operated. Therefore, the operation of the fan 56 corresponding to the battery 32 not capable of inputting and outputting power (for example, a fully charged battery 32) is restricted. Thus, by setting the third noise threshold to the upper noise limit value, it is possible to reduce the noise volume of the power device 10 to the upper noise limit value or less.

[0100] In addition to the above disclosure, the following notes are also disclosed.

[0101] (Appendix 1) A temperature control device (90) that adjusts the temperature of a temperature control target (10), the temperature control device includes a control unit (68) that controls the temperature control device, and the control unit controls the temperature control device based on an upper limit value of the noise level of a main device (10) in which the temperature control device is installed and that is the temperature control target, which is dissipated from the main device to the outside of the main device, or an upper limit value of the operating amount of the temperature control device or the main device corresponding to the upper limit value of the noise level of the main device.

[0102] According to this configuration, an upper limit value for the noise volume of the main unit that is dissipated from the main unit in which the temperature control device is installed to the outside of the main unit, or an upper limit value for the operation volume of the temperature control device or the main unit corresponding to the upper limit value for the noise volume of the main unit is set. As a result, even if the noise suppression method for each part of the main unit is not known, the noise volume of the main unit can be suppressed to below the upper limit value of the noise volume by controlling the temperature control device based on the upper limit value of the noise volume of the main unit or the upper limit value for the operation volume of the temperature control device or the main unit. As a result, the noise of the main unit can be easily and reliably suppressed regardless of the installation location and time of day of the main unit.

[0103] (Appendix 2) In the temperature adjustment device described in Supplementary Note 1, the upper limit value of the noise amount may be determined based on a location or area where the main device is installed.

[0104] According to this configuration, the upper limit of the noise level is determined based on the location or area where the main unit is installed. This makes it possible to determine the upper limit of the noise level in accordance with the noise regulation value for that location or area set by laws and regulations, etc. As a result, the noise of the main unit can be appropriately suppressed.

[0105] (Appendix 3) In the temperature adjustment device according to Supplementary Note 1 or 2, the upper limit of the noise amount may be determined based on a time or a time period during which the temperature adjustment device operates.

[0106] According to this configuration, the upper noise limit is set based on the time or time period when the temperature control device is operating. This allows the upper noise limit to be set in accordance with the noise regulation value for that time or time period set by laws and regulations. As a result, the noise of the main device can be appropriately suppressed. In addition, the upper noise limit can be changed as appropriate for environments where the noise regulation value differs depending on the time or time period, making it easy to use.

[0107] (Appendix 4) In the temperature control device described in any one of Appendices 1 to 3, the main device is an electric power device (10) having a housing (22) and an electrically operated unit (50, 52) housed inside the housing, and the temperature control device may further include air-generating units (55, 56) that promote the flow of air inside and outside the housing.

[0108] According to this configuration, the airflow generating section promotes the flow of air inside and outside the housing, so that when the electrically operated unit housed inside the housing is operating and generating heat, the temperature inside the housing including the electrically operated unit can be appropriately adjusted.

[0109] (Appendix 5) In the temperature adjustment device described in Appendix 4, the control unit controls the temperature adjustment device based on an upper limit value of the operating amount of the temperature adjustment device, and the upper limit value of the operating amount may be an upper limit airflow amount of the air generation section.

[0110] According to this configuration, the upper limit of the operating amount of the temperature adjustment device is the upper limit airflow rate of the airflow generating section. In other words, when the airflow generating section is operated, the operating sound of the airflow generating section becomes noise that is dissipated from the main unit to the outside. Therefore, by controlling the temperature adjustment device based on the upper limit airflow rate of the airflow generating section, it is possible to adjust the temperature inside the housing while suppressing the noise of the main unit.

[0111] (Appendix 6) In the temperature adjustment device according to appendix 4 or 5, the temperature adjustment device may further include a heat exchanger (57).

[0112] According to this configuration, since the temperature adjustment device includes a heat exchanger, the temperature inside the housing can be easily and effectively adjusted.

[0113] (Appendix 7) In the temperature adjustment device described in Appendix 6, the control unit controls the temperature adjustment device based on an upper limit value of the operating amount of the temperature adjustment device, and the upper limit value of the operating amount may be an upper limit heat exchange amount of the heat exchanger.

[0114] According to this configuration, the upper limit of the operating amount of the temperature adjustment device is the upper limit heat exchange amount of the heat exchanger. That is, when the heat exchanger is operated, the operating sound of the heat exchanger becomes noise that is dissipated from the main device to the outside. Therefore, by controlling the temperature adjustment device based on the upper limit heat exchange amount of the heat exchanger, it is possible to adjust the temperature inside the housing while suppressing the noise of the main device.

[0115] (Appendix 8) In the temperature adjustment device described in any one of Appendices 1 to 7, the main device may be an electric power device having an electric operation unit (50, 52) therein, and the electric power device may have an external connection unit (81) electrically connected to the electric operation unit and to which an external power source is connected, and an internal connection unit (86) electrically connected to the electric operation unit and to which an internal power storage unit (32) is connected.

[0116] According to this configuration, since the temperature adjustment device is provided in the power device, the temperatures of the electrically operated portion and the power storage portion can be appropriately adjusted.

[0117] (Appendix 9) In the temperature adjustment device described in Supplementary Note 8, the temperature adjustment device may further include a first temperature adjustment unit (55) that adjusts the temperature of the electrical operation unit, and a second temperature adjustment unit (56) that adjusts the temperature of the power storage unit.

[0118] According to this configuration, the first temperature adjustment unit adjusts the temperature of the electric operation unit, and the second temperature adjustment unit adjusts the temperature of the power storage unit, thereby making it possible to appropriately and efficiently adjust the temperatures of the electric power device including the electric operation unit and the power storage unit.

[0119] (Appendix 10) In the temperature control device described in Appendix 9, the control unit controls the temperature control device based on an upper limit value of the operating amount of the temperature control device, and the upper limit temperature control amount of the first temperature control unit, which is the upper limit value of the operating amount, may be changed based on the temperature of the electrical operation unit or the temperature of the space in which the electrical operation unit is placed.

[0120] According to this configuration, the upper limit temperature adjustment amount of the first temperature adjustment unit is changed based on the temperature of the electric operation unit or the temperature of the space in which the electric operation unit is placed. That is, when the first temperature adjustment unit operates, the operating sound of the first temperature adjustment unit becomes noise that is dissipated from the main unit to the outside. Therefore, by controlling the temperature adjustment device based on the changed upper limit temperature adjustment amount of the first temperature adjustment unit, it is possible to suppress the noise of the main unit while adjusting the temperature of the electric operation unit or the space.

[0121] (Appendix 11) In the temperature adjustment device described in Supplementary Note 9 or 10, the upper limit value of the operating amount of the temperature adjustment device may be a target value of a duty for the control unit to control each of the first temperature adjustment unit and the second temperature adjustment unit.

[0122] According to this configuration, the upper limit of the operation amount of the temperature adjustment device is the target value of the duty of each of the first temperature adjustment unit and the second temperature adjustment unit, and by controlling each of the first temperature adjustment unit and the second temperature adjustment unit based on the target value, the temperatures of the electric operation unit and the power storage unit can be adjusted with high accuracy.

[0123] (Appendix 12) In the temperature adjustment device according to any one of Supplementary Notes 9 to 11, the control unit may limit the operation of the first temperature adjustment unit when the upper limit value of the noise amount is equal to or lower than a first noise threshold value.

[0124] According to this configuration, when the upper limit value of the noise level of the power device is equal to or lower than the first noise threshold, the operation of the first temperature adjustment unit is restricted. As a result, by setting the first noise threshold to the noise regulation value, it is possible to reduce the noise level of the main device to or lower than the noise regulation value.

[0125] (Appendix 13) In the temperature adjustment device according to any one of Supplementary Notes 9 to 12, the control unit may limit the operation of the second temperature adjustment unit when the upper limit value of the noise amount is equal to or lower than a second noise threshold value.

[0126] According to this configuration, when the upper limit value of the noise level of the power device is equal to or lower than the second noise threshold, the operation of the second temperature adjustment unit is restricted. As a result, by setting the second noise threshold to the noise regulation value, it is possible to reduce the noise level of the main device to or lower than the noise regulation value.

[0127] (Appendix 14) In the temperature control device described in any one of Appendices 9 to 13, the power device has a plurality of the power storage units, and the temperature control device further includes a plurality of the second temperature control units that adjust the temperatures of the plurality of power storage units, and when the upper limit value of the noise level is equal to or lower than a third noise threshold, the control unit may operate only a second temperature control unit among the plurality of second temperature control units that corresponds to a power storage unit that is capable of inputting and outputting power.

[0128] According to this configuration, when the upper limit value of the noise level of the power device is equal to or lower than the third noise threshold, only the second temperature adjustment unit corresponding to the power storage unit capable of inputting and outputting power is operated. Therefore, the operation of the second temperature adjustment unit corresponding to the power storage unit that is not capable of inputting and outputting power (for example, a fully charged power storage unit) is restricted. As a result, by setting the third noise threshold to the noise regulation value, it is possible to reduce the noise level of the main device to or lower than the noise regulation value.

[0129] (Appendix 15) An electric power device comprising a temperature adjustment device according to any one of claims 1 to 14, the temperature of which is adjusted by the temperature adjustment device.

[0130] According to this configuration, an upper limit value of the noise amount of the electric power device that is dissipated from the electric power device in which the temperature adjustment device is installed to the outside of the electric power device, or an upper limit value of the operation amount of the temperature adjustment device or the electric power device corresponding to the upper limit value of the noise amount is set. As a result, even if the noise suppression method for each part of the electric power device is not known, the noise amount of the electric power device can be suppressed to or below the upper limit value by controlling the temperature adjustment device based on the upper limit value of the noise amount or the upper limit value of the operation amount of the temperature adjustment device or the electric power device. As a result, the noise of the electric power device can be easily and reliably suppressed regardless of the installation location and time of the electric power device.

[0131] (Appendix 16) A control method for a temperature adjustment device that adjusts the temperature of a temperature-adjusted object, the control method including a first step (S2-S5) of setting an upper limit value for the noise level of a main device that is dissipated from a main device in which the temperature adjustment device is installed to the outside of the main device, or an upper limit value for the operating amount of the temperature adjustment device or the main device corresponding to the upper limit value of the noise level of the main device, and a second step (S6) of controlling the temperature adjustment device based on the upper limit value of the noise level of the main device, or the upper limit value of the operating amount of the temperature adjustment device or the main device.

[0132] According to this method, an upper limit value for the noise volume of the main unit that is dissipated from the main unit in which the temperature control device is installed to the outside of the main unit, or an upper limit value for the operation volume of the temperature control device or the main unit corresponding to the upper limit value for the noise volume of the main unit, is set. As a result, even if the noise suppression method for each part of the main unit is not known, the noise volume of the main unit can be suppressed to below the upper limit value of the noise volume by controlling the temperature control device based on the upper limit value of the noise volume of the main unit or the upper limit value for the operation volume of the temperature control device or the main unit. As a result, the noise of the main unit can be easily and reliably suppressed regardless of the installation location and time of day of the main unit.
