Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, it is desirable to suppress an increase in the product size of a power supply device installed indoors. However, in a power supply device including a management device, the product size increases by the size of the management device. Therefore, there is still room for improvement in suppressing an increase in the product size of the power supply device. An object of the present invention is to suppress an increase in the product size of a power supply device including a power storage module and a management device.

[0008] [Summary of this invention] [1] The power supply device according to the present disclosure comprises a plurality of energy storage modules, a management device for managing the energy storage modules, and a rectangular parallelepiped housing in which the energy storage modules and the management device are housed, the housing comprising a battery housing chamber in which the energy storage modules are housed, and a management device housing chamber provided on one side in the left-right direction relative to the battery housing chamber, in which the management device is housed.

[0009] In the power supply unit with the above configuration, the housing has a control device housing on one side in the left-right direction of the battery housing where the energy storage module is housed, and a control device housing on the other side. As a result, the battery housing and the control device housing are arranged side by side in the left-right direction within the housing, which suppresses the increase in the height dimension of the housing compared to, for example, the case where the control device housing is located above the battery housing, and consequently suppresses the increase in the product size of the power supply unit.

[0010] [2] The power supply device described in [1] above, wherein the housing comprises a partition member extending in the vertical direction and dividing the inside of the housing into a battery housing and a plurality of control device housings, and an upper partition member provided above the partition member and having ventilation holes that open in the vertical direction, and the partition member may have heat dissipation grooves that open in the left-right direction on the control device housing side and extend in the vertical direction to the ventilation holes.

[0011] In the above configuration, the partition members that divide the inside of the enclosure into a battery compartment and multiple control device compartments are equipped with heat dissipation grooves, and these heat dissipation grooves extend to ventilation holes in the upper partition member provided at the top of the partition members. As a result, heat dissipated from the control devices can be released to the outside of the control device compartments through the ventilation holes via the heat dissipation grooves, making it difficult for heat to accumulate inside the control device compartments. Consequently, the adverse effects of heat on the control devices housed inside the enclosure can be suppressed.

[0012] [3] The power supply device according to [2] above, wherein the housing is provided with a plurality of management device accommodation chambers arranged vertically, the housing includes a plurality of shelf plate members that partition the interior of the housing into the plurality of management device accommodation chambers, and the plurality of shelf plate members may be provided with heat dissipation holes penetrating in the vertical direction. In the above configuration, since the heat dissipation holes are provided in the shelf plate members that partition the interior of the housing into the plurality of management device accommodation chambers, the heat in each management device accommodation chamber can be released to the outside of the management device accommodation chamber through the ventilation holes of the upper partition member through these heat dissipation holes. As a result, even in a configuration where the housing includes a plurality of management device accommodation chambers arranged vertically, heat is less likely to accumulate in each management device accommodation chamber, and the adverse effect of heat on the management devices housed in the housing can be suppressed.

[0013] [4] The power supply device according to [3] above, wherein the shelf plate member includes a support plate portion and a guide portion that stands upright from the support plate portion and guides the insertion of the management device into the management device accommodation chamber. In the support plate portion, with the guide portion as a reference, on one side in the left-right direction, the management device is arranged, and on the other side in the left-right direction, a heat dissipation hole may be provided. In the above configuration, by inserting the management device into the management device accommodation chamber along the guide portion, the management device can be arranged at a position avoiding the heat dissipation hole in the support plate portion. As a result, during the assembly or maintenance of the power supply device, the operator can arrange the management device at an appropriate position avoiding the heat dissipation hole without looking into the interior of the management device accommodation chamber.

[0014] [5] The power supply device according to any one of [1] to [4] above, further comprising a power control device arranged outside the housing and connected to the management device via wiring, and the housing may include a wiring accommodation chamber below the management device accommodation chamber for drawing out the wiring connected to the management device. In the above configuration, by drawing out the wiring connecting the management device and the power control device to the wiring accommodation chamber below the management device accommodation chamber, the routing of the wiring in the housing can be facilitated.

[0015] [Embodiment] The power supply device according to this embodiment will be described by taking a UPS (abbreviation for Uninterruptible Power System) as an example. The UPS1 shown in FIGS. 1 and 2 is a device assumed to be installed indoors and is connected between a system power supply (not shown) and a load. Normally, the UPS1 supplies power to the load by controlling the power supplied from the system power supply in a constant manner. On the other hand, the UPS1 can supply power from the power storage module 31 (shown in FIG. 2) to the load during a power outage. In this embodiment, the system power supply is an AC power supply that outputs AC power, and the load is a device driven by AC power.

[0016] In the following description, in the state where the UPS1 is viewed from the front side, the left - right direction is the left - right direction X, the up - down direction is the up - down direction Y, and the front - back direction is the front - back direction Z. The front - back direction Z is also the depth direction of the UPS1.

[0017] As shown in FIG. 1, the UPS1 includes an input / output board 2, a power supply board 3, and a battery board 4. The input / output board 2 houses an input / output unit 10, and the power supply board 3 houses a power control unit 20. The battery board 4 houses a plurality of power storage modules 31 (an example of a power storage module), a management device 40, and a protection unit 37. The input / output board 2, the power supply board 3, and the battery board 4 are arranged side by side in this order in the left - right direction X. In other words, the power supply board 3 is arranged next to the battery board 4.

[0018] First, the electrical configuration of UPS1 will be explained using Figure 2. The input / output unit 10 housed in the input / output panel 2 is a device that inputs, outputs, and interrupts power from the power supply. It is connected to the grid power supply via the main input terminal 11 and to the load via the main output terminal 12. The main input terminal 11 is a terminal into which AC power from the grid power supply is input, and the main output terminal 12 is an output terminal that outputs AC power to the load. The main input terminal 11 is connected to the first conductive path 13, and the main output terminal 12 is connected to the second conductive path 15. A power control unit 20 is connected between the first conductive path 13 and the second conductive path 15 via a terminal. Electromagnetic switches 13A and 15A are provided on the first conductive path 13 and the second conductive path 15, respectively.

[0019] A maintenance bypass path 17 is connected to the first conductive path 13 and the second conductive path 15. One end of the maintenance bypass path 17 is connected to the position between the main input terminal 11 and the electromagnetic switch 13A in the first conductive path 13, and the other end is connected to the position between the electromagnetic switch 15A and the main output terminal 12 in the second conductive path 15. An electromagnetic switch 17A is provided in the maintenance bypass path 17.

[0020] In the input / output unit 10 with the above configuration, the conductive path between the grid power supply and the load can be switched between a path via the power control unit 20 and a path that does not go through the power control unit 20. Specifically, by closing both electromagnetic switches 13A and 15A and opening electromagnetic switch 17A, the main input terminal 11 and the main output terminal 12 are connected by a path that includes the first conductive path 13, the power control unit 20, and the second conductive path 15. On the other hand, by opening both electromagnetic switches 13A and 15A and closing electromagnetic switch 17A, the main input terminal 11 and the main output terminal 12 are connected by a path that includes only the maintenance bypass path 17 without going through the power control unit 20.

[0021] The power control unit 20 housed in the power distribution panel 3 is a device that controls and outputs power input via the input / output unit 10 or power from the battery panel 4. The power control unit 20 mainly comprises a third conductive path 23, a fourth conductive path 24, a fifth conductive path 25, a rectifier 26, and an inverter 27. Electromagnetic switches 23A, 24A, and 25A are provided for each conductive path 23, 24, and 25, respectively. The input side of the third conductive path 23 is connected to the input / output unit 10 via a terminal, and its output side is connected to the rectifier 26. The rectifier 26 is a circuit that converts AC voltage to DC voltage, and its output side is connected to the input side of the inverter 27 via the fourth conductive path 24. The inverter 27 is a circuit that converts DC voltage to AC voltage, and its output side is connected to the fifth conductive path 25.

[0022] The fourth conductive path 24 is branched via an electromagnetic switch 24A, and the branched end is connected to the battery panel 4. The power control unit 20 may also include a bypass line that outputs the power input from the input / output unit 10 without passing through the third, fourth, and fifth conductive paths 23, 24, and 25.

[0023] In the power control unit 20 with the above configuration, by closing both electromagnetic switches 23A and 25A and opening electromagnetic switch 24A, the AC voltage supplied via the input / output unit 10 can be converted to a DC voltage by the rectifier 26, and then converted back to an AC voltage by the inverter 27. The AC voltage converted by the inverter 27 is supplied to the second conductive path 15 of the input / output unit 10 via the transformer 25B of the fifth conductive path 25. On the other hand, the power control unit 20 can open electromagnetic switch 23A and close both electromagnetic switches 24A and 25A, so that the DC voltage supplied from the battery panel 4 can be converted to an AC voltage by the inverter 27, and then supplied to the second conductive path 15 of the input / output unit 10 via the transformer 25B.

[0024] (Regarding the battery panel) Next, the configuration of the battery panel 4 will be described. The battery panel 4 comprises a plurality of energy storage modules 31, a management device 40 that manages each energy storage module 31, and a housing (shown in Figure 3) that houses each energy storage module 31 and the management device 40.

[0025] The energy storage module 31 mainly comprises a plurality of energy storage cells 32 and a battery monitoring board 33. The plurality of energy storage cells 32 are connected in series between positive and negative terminals (not shown) to form a single battery pack. Each energy storage cell 32 is, for example, a lithium-ion battery cell, and its shape may be a prismatic cell, a cylindrical cell, or a laminated cell. The battery monitoring board 33 measures the voltage from each energy storage cell 32 and communicates the measurement results to the management device 40.

[0026] Multiple energy storage modules 31 are connected by wiring (not shown) to form multiple groups (banks). In this embodiment, eight energy storage modules 31 are connected in series to form one bank. Note that the multiple energy storage modules 31 constituting each bank may be connected in parallel as well as in series. The number of energy storage modules 31 constituting each bank can be arbitrarily selected. Furthermore, when the energy storage modules 31 constituting each bank are connected in parallel, a domain is formed. That is, the multiple energy storage modules 31 are structured hierarchically in terms of banks and domains that aggregate these banks.

[0027] Each energy storage module 31 constituting a bank is connected to a power line 36 via a protection unit 37. The power line 36 is connected to the power control unit 20, which has already been described, via terminals. The protection unit 37 is equipped with an electromagnetic switch, and its open / closed state is controlled by the management device 40A, which allows switching between supplying power from each bank to the power line 36.

[0028] Each bank and domain is equipped with a management device 40 for managing the energy storage modules 31. The management device 40 is a device that includes a CPU, ROM, RAM, and a communication unit. In the following, when distinguishing between the management devices 40 provided in the banks and the management devices 40 provided in the domains, the former will be referred to as management devices 40A and 40B, and the latter as management device 40C.

[0029] The management devices 40A and 40B installed in the bank can communicate with the battery monitoring board 33 built into each energy storage module 31 in the bank via serial communication over a communication line, using a communication unit. The management devices 40A and 40B acquire status data of the energy storage cells inside the energy storage module 31. The management devices 40A and 40B also acquire temperature data measured in the energy storage module 31 and current data measured separately for each bank. In addition to the above, the management devices 40A and 40B may also perform management processing such as detecting abnormalities in the communication status.

[0030] The management device 40C located in the domain can communicate with the management devices 40A and 40B located in the bank via a communication bus. The communication bus is, for example, a CAN (Controller Area Network) bus. In addition, the communication bus may be a LAN cable or an ECHONET / ECHONETLite (registered trademark) compatible communication medium. The management device 40C aggregates the status data acquired by the management devices 40A and 40B and transmits the aggregated status data to an external device via a communication device (not shown). The communication device may be a network card type device (network interface card) or another type of device.

[0031] Figure 4 shows the external appearance of the control device 40. The control device 40 comprises a metal housing 41. The housing 41 comprises a rectangular base portion 44 having a mounting surface to which the circuit board portion 43 is attached, and a pair of side wall portions 45 extending from opposite sides of the base portion 44. The housing 41 has a housing chamber capable of accommodating the circuit board portion 43, and the front ends of the side wall portions 45 are open. A front plate 42 is attached to the front side of the housing 41. The front plate 42 has a number of connectors connected to the circuit board portion 43. As already described, the circuit board portion 43 can acquire status data of the energy storage cells 32 from the battery monitoring board 33 and current data measured by the current sensor, and transmit this information through the connectors on the front plate 42.

[0032] The control devices 40A and 40B can, for example, shut off the power supply from the bank by opening the electromagnetic contactor of the protection unit 37 if the current flowing through the bank, as detected by the current sensor, shows an abnormal value. In addition, the control devices 40A and 40B may be configured to open the electromagnetic contactor of the protection unit 37 if the status data shows an abnormal value.

[0033] As shown in Figures 3 and 5, the battery panel 4 comprises a housing 50 which includes a battery housing 70 for housing the energy storage module 31, a management device housing 71 for housing multiple management devices 40, and a protection unit housing 72 for housing the protection unit 37. The housing 50 is a cabinet type with an openable / closable door (not shown) on the front side, and is constructed by fixing multiple metal members with bolts and welding.

[0034] As shown in Figure 6, the housing 50 is provided with a frame 51 below it that supports the battery panel 4. The frame 51 is a rectangular member in plan view. Four columnar members 52 are fixed to each of the four corners of the frame 51 with their long sides facing the vertical direction Y. Below the columnar members 52, four lower frame members 53 are fixed, connecting each columnar member 52 in the left-right direction X and the front-back direction Z. Above the columnar members 52, four upper frame members 54 are fixed, connecting each columnar member 52 in the left-right direction X and the front-back direction Z. A rectangular ceiling member 55 is fixed to the top of the columnar members 52 in plan view. The ceiling member 55 has multiple ventilation holes 56 formed, for example, by punching, which allow heat from inside the housing 50 to escape.

[0035] In the housing 50, below the ceiling member 55, an upper partition member 62 is provided that separates the protective unit housing chamber 72 from the battery housing chamber 70 and the control device housing chamber 71 within the housing 50. As shown in Figure 7, the upper partition member 62 is rectangular in plan view and is fixed between four columnar members 52 by bolts or the like, with its thickness direction oriented in the vertical direction Y. In this embodiment, the protective units 37 corresponding to each bank are installed on the front side inside the protective unit housing chamber 72. This allows workers to easily access the protective units 37 when they open the opening / closing door.

[0036] In the upper partition member 62, ventilation holes 63 and 64 are formed on the right and rear sides. The ventilation hole 63 is also a hole that communicates with the control device housing chamber 71 in the vertical direction Y.

[0037] As shown in Figure 6, in the housing 50, below the upper partition member 62, a partition member 80 is provided that divides the inside of the housing 50 into a battery storage compartment 70 and a control device storage compartment 71. The partition member 80 is a roughly rectangular plate and is fixed between the upper partition member 62 and the base 51 with its thickness direction oriented in the left-right direction X. The length dimension of the partition member 80 in the front-rear direction Z is approximately the same as the length dimension of the base 51 in the front-rear direction Z, and it divides the inside of the housing 50 into left and right spaces (i.e., the battery storage compartment 70 and the control device storage compartment 71) across the front-rear direction Z. The detailed configuration of the partition member 80 will be described later.

[0038] In the housing 50, a first shelf member 60 is provided to the left of the partition member 80 in the left-right direction X, which partitions the inside of the housing 50 into multiple battery housing compartments 70. In this embodiment, eight first shelf members 60 are fixed to the housing 50 in an orderly manner in the vertical direction Y, thereby forming eight battery housing compartments 70 arranged in the vertical direction Y.

[0039] As shown in Figure 8, the first shelf member 60 is a substantially rectangular plate material, fixed between the columnar members 52 with its thickness direction oriented in the vertical direction Y. Two energy storage modules 31A and 31B are housed side by side in the left-right direction X in one battery housing chamber 70. A partition projection 61 is provided on the upper surface of the first shelf member 60, extending in the front-back direction Z from the center in the left-right direction X. In this embodiment, energy storage module 31A is housed to the left of the partition projection 61 in the battery housing chamber 70, and energy storage module 31B is housed to the right of the partition projection 61. By arranging the energy storage modules 31A and 31B, which constitute different banks, to the left and right of the partition projection 61 in the battery housing chamber 70, eight vertically aligned energy storage modules 31A and 31B that constitute the same bank can be arranged together on one side in the left-right direction X. This makes it possible to suppress an increase in the wiring length for conductive paths such as busbars that connect each energy storage module 31.

[0040] As shown in Figure 6, in the housing 50, a second shelf member 90 is provided to the right of the partition member 80 in the left-right direction X, partitioning the inside of the housing 50 into multiple control device housing compartments 71. The control device housing compartment 71 is a space whose dimensions in the left-right direction X are shorter than those of the battery housing compartment 70. As shown in Figure 3, the control device 40 is housed in the control device housing compartment 71 with the open side of the housing 41 facing the partition member 80 in the left-right direction X. Since the dimensions of the control device housing compartment 71 in the left-right direction X are shorter than those of the battery housing compartment 70, an increase in the width dimension of the UPS1 can be suppressed. In this embodiment, three second shelf members 90 are fixed in the housing 50 in a vertical direction Y, thereby forming three vertically aligned control device housing compartments 71.

[0041] The second shelf member 90 is a plate that is roughly rectangular in shape when viewed from above, and is fixed between the columnar member 52 and the partition member 80 with its thickness direction oriented in the vertical direction Y. As shown in Figure 3, of the three control device housing rooms 71, the bank control device 40A is housed in the highest control device housing room 71A. The bank control device 40B is housed in the intermediate control device housing room 71B. The domain control device 40C is housed in the lowest control device housing room 71C.

[0042] As shown in Figure 6, in the housing 50, below the control device housing chamber 71, there is a wiring housing chamber 73 through which the wiring from each control device 40A to 40C is routed. In this embodiment, each control device 40A to 40C is connected to the power control unit 20 via wiring and receives drive power from the power control unit 20. Therefore, the wiring from the power control unit 20 is drawn into the housing 50 through an outlet hole provided in the side wall of the housing 50. The drawn-in wiring is then routed within the wiring housing chamber 73 before being connected to each control device 40A to 40C. This allows the wiring connected to each control device 40A to 40C to be arranged within the wiring housing chamber 73 located below before being connected to each control device 40A to 40C.

[0043] (Regarding the control device housing room) Next, the partition member 80 and the second shelf member 90 forming the control device housing 71 will be described in detail using Figures 9, 10, and 11. Note that Figure 10 shows the state in which the control devices 40A to 40C are not attached to the housing 50. Figure 11 shows the state in which only the control device 40A is not attached to the housing 50.

[0044] As shown in Figures 10 and 11, the partition member 80 has two convex portions 82 that protrude convexly from the surface 81 facing the control device housing room 71 and extend in the vertical direction Y. The convex portions 82 also support the upper partition member 62, which is provided above the partition member 80, from below. The two convex portions 82 are located at a predetermined distance apart in the front-rear direction Z on the surface 81 side, and a heat dissipation groove 83 extending in the vertical direction Y is formed between the two convex portions 82.

[0045] As shown in Figure 9, the second shelf member 90 includes a support plate portion 91 that supports the control device 40 from below, and a first guide portion 92 and a second guide portion 93 that guide the insertion of the control device 40 into the control device housing chamber 71. The support plate portion 91 is a substantially rectangular portion in plan view. The first guide portion 92 is a portion that extends upward from the support plate portion 91 and extends in the front-rear direction Z. The second guide portion 93 is to the right of the first guide portion 92 in the left-right direction X, and extends upward from the support plate portion 91 and extends in the front-rear direction Z. The height of the first guide portion 92 from the support plate portion 91 is lower than that of the second guide portion 93. In the support plate portion 91, the area enclosed by the first guide portion 92 and the second guide portion 93 is the area where the control device 40 is placed.

[0046] The second shelf member 90 has heat dissipation holes 94 formed on the side opposite to the area where the control device 40 is positioned, with reference to the first guide portion 92, in the left-right direction X. In this embodiment, the first guide portion 92 is formed by cutting and raising a part of the support plate portion 91, and the holes formed by cutting and raising the first guide portion 92 are the heat dissipation holes 94.

[0047] In the second shelf member 90 of the above configuration, when assembling or maintaining the battery panel 4, the control device 40 can be inserted from the front side of the control device housing chamber 71 along the first and second guide sections 92 and 93, thereby positioning the control device 40 in an appropriate location that avoids the heat dissipation holes 94 in the support plate section 91. This prevents the heat dissipation holes 94 from being blocked by the control device 40.

[0048] As shown in Figure 8, the side surface of the second shelf member 90 is fixed inside the housing 50 in contact with the convex portion 82, and a heat dissipation groove 83 extending in the vertical direction Y is located between the second shelf member 90 and the partition member 80. Therefore, the three control device housing chambers 71A to 71C are connected in the vertical direction Y via the heat dissipation groove 83. Furthermore, the upper end of the heat dissipation groove 83 extends to the ventilation hole 63 (shown in Figure 7) of the upper partition member 62 provided on the upper part of the partition member 80, so that the heat flowing through the heat dissipation groove 83 can be discharged to the outside of the control device housing chamber 71 through the ventilation hole 63.

[0049] The control device 40 housed in the control device housing 71 has its open side (shown in Figure 4) facing the heat dissipation grooves 83 and heat dissipation holes 94 in the left-right direction X. Also, the height of the first guide portion 92 is lower than that of the second guide portion 93. Therefore, heat from the circuit board portion 43 of the control device 40 tends to accumulate towards the heat dissipation grooves 83 and heat dissipation holes 94, thereby enhancing the heat dissipation effect of the control device housing 71. Heat from the control device housing 71B and 71C flows upward through the heat dissipation grooves 83 and heat dissipation holes 94, reaching the control device housing 71A. The heat that reaches the control device housing 71A then flows into the protective unit housing 72 through the ventilation holes 63 of the upper partition member 62 and is dissipated to the outside of the housing 50 through the ventilation holes 56 of the ceiling member 55.

[0050] Furthermore, when an operator performs maintenance work on the battery panel 4, they open an unillustrated door to access the energy storage module 31, the control device 40, and the protection unit 27 housed in the housing 50. At this time, since the front sides of the battery housing 70, the control device housing 71, and the protection unit housing 72 are open in the housing 50, the operator can access the devices housed in each housing 70, 71, and 72 from the front side of the housing 50. As a result, work efficiency during maintenance is improved.

[0051] (Effects of the present invention) The present invention, as described above, can achieve the following effects. The housing 50 of the battery panel 4 is provided with a battery housing 70 in which the energy storage module 31 is housed, and a management device housing 71 in which the management device 40 is housed, on one side in the left-right direction X relative to the battery housing 70. As a result, compared to, for example, the case in which the management device housing 71 is placed above the battery housing 70, an increase in the height dimension of the housing 50 can be suppressed.

[0052] The partition member 80 that divides the inside of the housing 50 into a battery compartment 70 and a control device compartment 71 is equipped with a heat dissipation groove 83. As a result, heat from the control device 40 can be released to the outside of the control device compartment 71 through the heat dissipation groove 83 and the ventilation holes 63 of the upper partition member 62. This makes it less likely for heat to accumulate inside the control device compartment 71, and the adverse effects of heat on the control device 40 housed inside the housing 50 can be suppressed.

[0053] Since the second shelf member 90 that partitions the inside of the housing 50 into multiple control device housing compartments 71 is provided with heat dissipation holes 94, heat inside each control device housing compartment can be released to the outside of the control device housing compartment 71 through these heat dissipation holes 94 and the ventilation holes 63 of the upper partition member 62. As a result, even in a configuration in which the housing 50 has multiple control device housing compartments 71 arranged in the vertical direction, heat is less likely to accumulate inside each control device housing compartment 71, and the adverse effects of heat on the control devices 40 housed inside the housing 50 can be suppressed.

[0054] The second shelf member 90 is equipped with a first guide portion 92 that guides the insertion of the control device 40 into the control device housing chamber 71. The control device 40 is positioned on one side in the left-right direction X relative to the first guide portion 92, and a heat dissipation hole 94 is formed on the other side in the left-right direction. In the above configuration, by inserting the control device 40 into the control device housing chamber 71 along the first guide portion 92, the control device 40 can be positioned in the support plate portion 91 while avoiding the heat dissipation hole 94. As a result, the worker can position the control device 40 in the control device housing chamber 71 in the correct position while avoiding the heat dissipation hole 94 without having to look inside the control device housing chamber 71.

[0055] The wiring connecting the control device 40 and the power panel 3 (power control device) is routed to a wiring storage room 73 located below the control device storage room 72, making it easier to route the wiring within the enclosure 50.

[0056] (Other embodiments) The present invention is not limited to the embodiments described above, and for example, the following embodiments are also included within the technical scope of the present invention. In the above embodiment, the UPS1 was composed of an input / output panel 2, a power supply panel 3, and a battery panel 4. However, the input / output panel 2 and the power supply panel 3 may be integrated, and the input / output unit 10 may be housed in the power supply panel 3.

[0057] In the above embodiment, the power control unit 20 converted the AC voltage to a DC voltage using a rectifier 26, and then converted it back to an AC voltage using an inverter 27 for output. Alternatively, if the UPS1 is connected to a grid power supply that provides DC power, the power control unit 20 may be configured to boost or step down the DC voltage from the power supply using a converter, and then convert it back to an AC voltage using an inverter 27 for output.

[0058] In the above embodiment, the multiple energy storage modules 31 constitute two banks. Alternatively, the multiple energy storage modules 31 may constitute only one bank. In this case, the UPS 1 may have only one control device 40, and the housing 50 may have one control device housing 71 next to the battery housing 70. In addition, if the multiple energy storage modules 31 constitute three or more banks, the UPS 1 may have four control devices 40. In this case, the housing 50 may have four control device housings 71 arranged vertically in the Y direction next to the battery housing 70.

[0059] In the above embodiment, the power supply device was described using UPS1 as an example. The power supply device may be any device comprising an energy storage module 31 and a management device 40, and may be, for example, an ESS (abbreviation for Energy Storage System).
