[Power storage system]
FIG. 1 is a diagram showing a configuration of a power storage system according to an embodiment of the present invention.

  Referring to FIG. 1, power storage system 401 includes a power generation device 511, a power conditioner 512, a load 513, a BMS (Battery Management System) 501, and a power supply device 101. The power conditioner 512 includes a converter circuit 531, an inverter circuit 533, and a bidirectional converter circuit 534. Power supply device 101 includes storage batteries B11 to B14, B21 to B24, B31 to B34, and B41 to B44. Hereinafter, each of the storage batteries B11 to B14, B21 to B24, B31 to B34, and B41 to B44 is also referred to as a storage battery B.

  In FIG. 1, one power generation device 511 is representatively shown, but a plurality of power generation devices 511 may be provided. In FIG. 1, one power supply device 101 is representatively shown, but a plurality of power supply devices 101 may be provided. In FIG. 1, one load 513 is representatively shown, but a plurality of loads 513 may be provided.

  The power storage system 401 is used, for example, as a buffer for energy output from solar power generation or the like in which generated power fluctuates, and for power failure countermeasures, and is installed at a business office or the like.

  More specifically, power generation device 511 in power storage system 401 includes a solar cell module 514, for example. The solar cell module 514 is constituted by a plurality of sets of solar cell panels, for example. For example, when each set of solar cell panels receives sunlight, it converts the energy of the received sunlight into DC power, and outputs the converted DC power to the power conditioner 512. The power generation device 511 may be another device capable of power generation such as a wind power generation device.

  The power conditioner 512 converts the electric power received from the power generation device 511 and outputs the converted electric power to the load 513 and the BMS 501.

  More specifically, the converter circuit 531 in the power conditioner 512 is connected between the power generation device 511, the inverter circuit 533, and the bidirectional converter circuit 534. Converter circuit 531 boosts the DC power received from power generation device 511, that is, the DC voltage, and outputs the boosted voltage to inverter circuit 533 and bidirectional converter circuit 534.

  Inverter circuit 533 is connected between converter circuit 531 and load 513. Inverter circuit 533 generates an AC voltage from the DC voltage received from converter circuit 531, and outputs the generated AC voltage to load 513.

  The load 513 is, for example, a communication device or a monitoring camera, and operates with an AC voltage received from the inverter circuit 533.

  Bidirectional converter circuit 534 is connected between converter circuit 531 and BMS 501. The bidirectional converter circuit 534 monitors, for example, the voltage and temperature of each storage battery B in the power supply device 101, and performs charge / discharge control of each storage battery B based on the monitoring result.

  More specifically, in the case where each storage battery B is discharged, bidirectional converter circuit 534 charges each storage battery B when the voltage of each storage battery B drops to the return voltage value. At this time, bidirectional converter circuit 534 generates a DC voltage that can charge each storage battery B by boosting or stepping down the DC voltage received from converter circuit 531, and outputs the DC voltage to power supply apparatus 101 via BMS 501. .

  Bidirectional converter circuit 534 discharges each storage battery B when the voltage of each storage battery B rises to the upper limit voltage value when charging each storage battery B. At this time, bidirectional converter circuit 534 boosts or steps down the DC voltage received from power supply device 101 via BMS 501 and outputs the boosted voltage to inverter circuit 533. Bidirectional converter circuit 534 changes the return voltage value and the upper limit voltage value according to the temperature of each storage battery B, for example.

  The BMS 501 is connected between the bidirectional converter circuit 534 and the power supply device 101. The BMS 501 monitors the voltage and temperature of each storage battery B in the power supply apparatus 101, and detects an abnormality of each storage battery B based on the monitoring result.

  Specifically, the BMS 501 switches between electrical connection and non-connection between the bidirectional converter circuit 534 and the power supply apparatus 101 using a relay. For example, when abnormality occurs in storage battery B11, BMS 501 electrically disconnects bidirectional converter circuit 534 and storage battery B11. As a result, the storage battery B11 exhibiting abnormality can be electrically disconnected from the power storage system 401.

  The storage battery B in the power supply device 101 is charged and discharged according to the control of the bidirectional converter circuit 534. Specifically, the storage battery B is, for example, a lithium ion secondary battery or a lead storage battery. The weight of the storage battery B is about 10 to 100 kilograms.

  Storage battery B has an anode and a cathode. Specifically, the storage batteries B11 to B14, B21 to B24, B31 to B34, B41 to B44 are respectively anodes TP11 to TP14, TP21 to TP24, TP31 to TP34, TP41 to TP44, and cathodes TM11 to TM14, TM21 to TM24. , TM31 to TM34, TM41 to TM44.

  Hereinafter, each of the anodes TP11 to TP14, TP21 to TP24, TP31 to TP34, and TP41 to TP44 is also referred to as an anode TP. Each of the cathodes TM11 to TM14, TM21 to TM24, TM31 to TM34, and TM41 to TM44 is also referred to as a cathode TM.

  Each storage battery B charges the DC power received from the bidirectional converter circuit 534 in the power conditioner 512 according to the voltage between the anode TP and the cathode TM of each storage battery B, and the energy stored by itself is stored in the DC power. To the bidirectional converter circuit 534.

[Problems in power supply]
FIG. 2 is a diagram showing a configuration of a comparative example of the power supply device according to the embodiment of the present invention.

  Referring to FIG. 2, a power supply device 901 that is a comparative example of power supply device 101 includes casing 902, doors 904FW and 904FE (not shown), doors 904RW and 904RE, shelves 925S0 to 925S5, and storage batteries B911 to B914 and B921. -B924, B931-B934, B941-B944. Hereinafter, the doors 904FW, 904FE, 904RW, and 904RE are also referred to as doors 904. Each of the shelves 925S0 to 925S5 is also referred to as a shelf 925. Each of storage batteries B911-B914, B921-B924, B931-B934, B941-B944 is also referred to as storage battery B900.

  On the shelves 925S1, 925S2, 925S3, and 925S4, storage batteries B911 to B914, B921 to B924, B931 to B934, and B941 to B944 are placed, respectively. Casing 902 includes drainers 903F and 903R.

  FIG. 2 shows a state where the front doors 904FE and 904FW are removed from the casing 902.

  Since the power supply device 901 including the heavy storage battery B900 is very heavy, it is installed on a foundation F905 made of concrete, for example.

  For example, when a worker replaces the storage battery B900, the replacement work of the storage battery B900 can be easily performed by using a hand lifter and performing replacement work by a plurality of workers.

  However, as shown in FIG. 2, for example, when the power supply device 901 is installed on the foundation F905, the leg 953 of the hand lifter 951 interferes with the foundation F905 even if the hand lifter 951 is approached from the front side of the power supply device 901. It is difficult to reach the tip of the fork portion 952 to the vicinity of the storage battery B900. In addition, the fork portion 952 may be further extended, but the hand lifter 951 may be out of balance and fall down.

  For example, when there is no foundation F905, the storage battery B900 can be easily replaced using the hand lifter 951. However, when the power supply device 901 is installed in a high place such as the rooftop and the top of a building, in a narrow place, or in an inconvenient place, the hand lifter 951 is brought into the place where the power supply device 901 is installed for replacement of the storage battery B900. Is difficult. In this case, the replacement of the storage battery B900 is performed manually by an operator. And it is recommended that the storage battery B900 placed on the shelf 925 be taken out by a plurality of workers.

  FIG. 3 is a sectional view showing a comparative example of the power supply device according to the embodiment of the present invention as seen from above.

  FIG. 3 shows a state where the front doors 904 FW and 904 FE are attached to the casing 902. The worker WM1 takes out the storage batteries B911 to B914 from the opening of the casing 902, for example, when replacing the storage batteries B911 to B914 placed on the shelf 925S1 from the front side of the power supply device 901.

  The width of the opening of the casing 902 is defined by, for example, the doors 904FW and 904FE. When the width of the opening of the casing 902 is, for example, not more than twice the shoulder width of the worker WM1, it is difficult for a plurality of workers to replace the storage battery.

  FIG. 4 is a cross-sectional view showing an enlarged cross-sectional view of the periphery of the door mounting portion when the door is fully closed in the comparative example of the power supply device according to the embodiment of the present invention.

  Referring to FIG. 4, main body hinge 907FE is fixed to drainer 903F in casing 902. Further, a door side hinge 906FE is fixed to the front door 904FE. The main body side hinge 907FE and the door side hinge 906FE can be rotated relative to each other about the axis R909FE.

  A packing 908FE is attached to the door 904FE. The packing 908FE seals between the door 904FE and the drainer 903F when the door 904FE is fully closed.

  FIG. 5 is a cross-sectional view showing an enlarged cross-sectional view of the vicinity of the door mounting portion when the door is fully opened in the comparative example of the power supply device according to the embodiment of the present invention.

  Referring to FIG. 5, door 904FE in the fully closed state shown in FIG. 4 is in a fully open state as shown in FIG. 5 by rotating by angle α about axis R909FE as a rotation axis. However, as shown in a region Rg1 in FIG. 5, the door 904FE interferes with the drainer 903F or the main body hinge 907FE, so that the opening angle α of the door 904FE is limited. Specifically, the angle α does not exceed 135 degrees, for example. Note that the opening angle of the doors 904FW, 904RW, and 904RE is also limited in the same manner as the opening angle α of the door 904FE.

  Referring to FIG. 3 again, since the opening angle α of the doors 904FW and 904FE is limited, the width between the front side of the doors 904FW and 904FE, that is, the opposite end of the rotating shaft is limited to the width Wr or less. For this reason, it becomes difficult for a plurality of workers to perform storage battery replacement work in the space between the doors 904FW and 904FE. In particular, when the bottom area of the casing 902 is small, the space between the doors 904FW and 904FE is more limited, so that it becomes more difficult for a plurality of workers to replace the storage battery.

  For this reason, since the operator has to lift the storage battery B, which is a heavy object, by one person, the replacement work of the storage battery becomes difficult. Moreover, the storage battery which can be used may be restrict | limited by weight.

  On the other hand, in the storage device according to the embodiment of the present invention, the above problem is solved by the following configuration and method.

As a result, the storage batteries B31 to B34 can be accommodated on the top surface of the shelf 121S3.

  The distance between the upper surface of the shelf 121S4 and the lower surfaces of the general-purpose plates 201F3 and 201R3 is made larger than the heights of the storage batteries B41 to B44, for example, by adjusting the height positions of the cross plates 224E3 and 224W3 or the cross plates 224E4 and 224W4. As a result, the storage batteries B41 to B44 can be accommodated on the top surface of the shelf 121S4.

  For example, the take-out space for taking out the storage battery B placed on the shelf 121 to the outside of the casing 102 is defined by the opening 301 and the shelf 121 of the casing 102.

  Specifically, as shown in FIG. 7, the take-out space 311U1 is defined by the openings 301F and 301R of the casing 102 and the shelves 121S0 and 121S1. In the storage device 161 shown in FIGS. 6 to 8, the take-out space 311U1 is entirely closed by the cover panels 131F1 and 131R1.

[Composition of shelf]
FIG. 9 is a perspective view of the shelf according to the embodiment of the present invention as viewed from the right side when the storage battery is placed.
FIG. 10 is a plan view of the shelf according to the embodiment of the present invention as viewed from above when the storage battery is placed.
FIG. 11: is a front view at the time of storage battery mounting of the shelf which concerns on embodiment of this invention.

  9 to 11 representatively show the shelf 121S1 with the cover panels 131F1 and 131R1 fully opened. The shelves 121S2 to 121S4 are the same as the shelves 121S1 shown in FIGS.

  The shelf 121S1 and the cover panel 131F1 are connected by cover panel hinges 135FW1 and 135FE1. Cover panel hinges 135FW1 and 135FE1 have shafts 135FW1R and 135FE1R, respectively.

  Similarly, the shelf 121S1 and the cover panel 131R1 are connected by cover panel hinges 135RW1 and 135RE1. Cover panel hinges 135RW1 and 135RE1 have shafts 135RW1R and 135RE1R, respectively.

  As shown in FIG. 7, the cover panels 131F1 and 131R1 completely close the extraction space 311U1 in the fully closed state. The cover panel 131F1 extends in the direction from the take-out space 311U1 to the outside of the storage device 161 as shown in FIG. 9 by rotating approximately 90 degrees from the fully closed state with the shafts 135FW1R and 135FE1R as rotation axes. The fully open state is such that the upper surface of the shelf 121S1 and the upper surface of the cover panel 131F1 form substantially the same plane. Hereinafter, the upper surface of the shelf 121 is also referred to as a placement surface 122. Further, the upper and lower surfaces of the cover panel 131 in the fully opened state are also referred to as a work surface 136 and a non-work surface, respectively. Cover panel 131F1 opens take-out space 311U1 in the fully opened state.

  Similarly, the cover panel 131R1 rotates approximately 90 degrees from the fully closed state about the shafts 135RW1R and 135RE1R as the rotation axis, thereby moving the cover panel 131R1 from the take-out space 311U1 to the outside of the storage device 161 as shown in FIG. It extends | stretches and it will be in the state at the time of full opening in which the mounting surface 122 in shelf 121S1 and the work surface 136 in cover panel 131R1 form a substantially identical plane. Cover panel 131R1 opens take-out space 311U1 in the fully opened state.

  The stay 151 is provided corresponding to the cover panel 131 and the shelf 121. Specifically, stays 151FW1 and 151FE1 are provided on cover panel 131F1 and shelf 121S1. The stays 151RW1 and 151RE1 are provided on the cover panel 131R1 and the shelf 121S1.

  More specifically, stays 151FW1 and 151FE1 have a first end fixed to cover panel 131F1 and a second end fixed to shelf 121S1. The stays 151RW1 and 151RE1 have a first end fixed to the cover panel 131R1 and a second end fixed to the shelf 121S1.

  Stays 151FW1, 151FE1, and 151RW1 and 151RE1 hold the cover panel 131F1 and 131R1 in a fully opened state, respectively. Further, the stays 151FW1, 151FE1, and 151RW1, 151RE1 are each bent to facilitate the transition from the fully opened state to the fully closed state of the cover panels 131F1 and 131R1.

  The cover panel 131, the stay 151, and the cover panel hinge 135 have at least a load resistance sufficient to support the weight of the storage battery B. Thereby, the storage battery B can be stably placed on the work surface 136 of the cover panel 131 when the cover panel 131 is fully opened.

  The first ends of the stays 151FW1 and 151FE1 are fixed to, for example, the work surface 136 of the cover panel 131F1 in the vicinity of the left end portion and the vicinity of the right end portion of the cover panel 131F1. Further, the second ends of stays 151FW1 and 151FE1 are fixed, for example, in the vicinity of the left front end portion and in the vicinity of the right front end portion of shelf 121S1, respectively.

  Further, the first ends of the stays 151RW1 and 151RE1 are fixed to, for example, the work surface 136 of the cover panel 131R1, in the vicinity of the left end portion and in the vicinity of the right end portion of the cover panel 131R1. Further, the second ends of the stays 151RW1 and 151RE1 are fixed, for example, in the vicinity of the left rear end portion and in the vicinity of the right rear end portion of the shelf 121S1, respectively.

  The distance between the first end of the stay 151FW1 and the first end of the stay 151FE1 and the distance between the second end of the stay 151FW1 and the second end of the stay 151FE1 are, for example, that of the storage batteries B13 and B14 placed on the shelf 121S1. Greater than the sum of the left and right lengths.

  With such a configuration, when the cover panel 131F1 is fully opened, the storage device 161 when the storage batteries B13 and B14 are moved on the plane formed by the placement surface 122 of the shelf 121S1 and the work surface 136 of the cover panel 131F1. Workability on the front side can be improved.

  Similarly, the distance between the first end of stay 151RW1 and the first end of stay 151RE1 and the distance between the second end of stay 151RW1 and the second end of stay 151RE1 are, for example, storage battery B11 placed on shelf 121S1. , B12 is greater than the sum of the left and right lengths.

  With such a configuration, when the cover panel 131R1 is fully opened, the storage device 161 when the storage batteries B11 and B12 are moved on a plane formed by the placement surface 122 of the shelf 121S1 and the work surface 136 of the cover panel 131R1. The workability on the rear side can be improved.

  For example, it is not preferable that the friction coefficient of the mounting surface 122 for fixing the storage battery B in the shelf 121 is too low. On the other hand, the friction coefficient of work surface 136 for moving storage battery B in cover panel 131 is preferably low. Therefore, in the storage device 161, for example, a member whose friction coefficient of a part or all of the work surface 136 of the cover panel 131 is smaller than the friction coefficient of the mounting surface 122 on which the storage battery B is mounted on the shelf 121 is used. It is done.

  Further, for example, a member is used in which the insulating property of a part or all of the work surface 136 of the cover panel 131 is higher than the insulating property of the mounting surface 122 in the shelf 121.

  Specifically, for example, resin materials 132F1 to 132F4 and 132R1 to 132R4 having a small coefficient of friction and a high specific resistance are attached to substantially the entire surface of the work surface 136 of the cover panels 131F1 to 131F4 and 131R1 to 131R4. . Hereinafter, each of the resin materials 132F1 to 132F4, 132R1 to 132R4 is also referred to as a resin material 132. The resin material 132 is a resin having sliding properties and insulating properties such as acrylic or polycarbonate.

  As described above, the configuration using the resin material 132 having a low friction coefficient allows the storage battery B, which is a heavy object, to slide on the resin material 132 when the cover panel 131 is fully opened. Thereby, the storage battery B can be easily moved on the resin material 132, without using special apparatuses, such as a trolley | bogie which mounts a storage battery.

  Moreover, since the insulation using the resin material 132 which is an insulator can be further ensured, the occurrence of a short circuit and electric shock can be suppressed. Specifically, for example, in a state in which the take-out space 311 is closed, the resin material 132 that is an insulator is disposed in the vicinity of the anode TP and the cathode TM of the storage battery B. Therefore, the storage battery B falls down due to vibration due to an earthquake or the like. Even in this case, occurrence of a short circuit and electric shock can be suppressed.

  In addition, for example, in the state where the take-out space 311 is opened, even when the conductive portion mistakenly contacts the work surface 136 when removing the connection cable from the anode TP or the cathode TM of the storage battery B, the occurrence of a short circuit and electric shock may occur. Can be suppressed.

  Note that the resin material 132 may be attached to a part of the work surface 136 of the cover panel 131. Specifically, the part of the work surface 136 may be an area where the storage battery B can move on the resin material 132.

  Further, for example, the stay 151 and the cover panel hinge 135 that are drive units are fixed to the shelf 121 and the cover panel 131 before the storage device 161 is shipped from the factory as a product, for example.

  With such a configuration, the drive unit, the shelf 121, and the cover panel 131 can be integrated before shipping as a product, so that the assembling property when the storage device 161 is installed in the field is improved, and the shelf 121 is provided. The versatility can be improved.

  In the storage device 161 according to the embodiment of the present invention, the cover panel 131 is configured such that the lower side thereof is connected to the shelf 121 and extends toward the outside of the storage device 161. However, the present invention is not limited thereto. is not. For example, the cover panel 131 may be configured such that the upper side thereof is connected to the shelf 121 and extends outward of the storage device 161.

  That is, the cover panel 131 forms substantially the same plane as the placement surface 122 of the upper shelf 121 among the shelves 121 that define the take-out space 311 to be closed in a state where the take-out space 311 is opened. In this case, the storage battery B included in the take-out space 311 where the cover panel 131 opens and closes is different from the storage battery B to be moved onto the work surface 136 of the cover panel 131.

  6 to 8 again, service plug 141 is provided corresponding to shelf 121 on which storage battery B is placed, for example. The service plug main body 142 and the service plug grip 143 in the service plug 141 are detachable, for example. The service plug 141 forms a part of an electrical connection path between the storage battery B placed on the corresponding shelf 121 and another storage battery B or BMS 501, for example.

  The service plug main body 142 is fixed to the general-purpose plate 201 fixed to the corresponding shelf 121 so that the service plug main body 142 can be engaged with the corresponding service plug grip 143, for example.

  Then, the service plug main body 142 is engaged with the corresponding service plug grip 143 while sandwiching a part of the cover panel 131 between the corresponding service plug grip 143 and the service plug main body 142, for example. Limit or fix the displacement.

  Specifically, the service plug bodies 142 of the service plugs 141FW1 and 141FE1 are fixed to the general-purpose plate 201F0 fixed to the front surface of the shelf 121S0 so as to be able to engage with the corresponding service plug grips 143, respectively.

  The service plug main body 142 of the service plugs 141FW1 and 141FE1 fixes the cover panel 131F1 by engaging with the corresponding service plug grips 143 while sandwiching the notches 133FW1 and 133FE1 in the cover panel 131F1, respectively. At this time, the take-out space 311U1 is closed by the cover panel 131F1.

  Similarly, the service plug bodies 142 of the service plugs 141RW1 and 141RE1 are fixed to a general-purpose plate 201R0 fixed to the rear surface of the shelf 121S0 so as to be able to engage with the corresponding service plug grips 143, respectively.

  The service plug bodies 142 of the service plugs 141RW1 and 141RE1 fix the cover panel 131R1 by engaging with the corresponding service plug grips 143 while sandwiching the notches 133RW1 and 133RE1 in the cover panel 131R1, respectively. At this time, the take-out space 311U1 is closed by the cover panel 131R1.

  That is, for example, when the service plug main body 142 of the service plug 141 engages with the corresponding service plug grip 143 with the notch 133 interposed therebetween, the service plug 141 closes the take-out space 311 with the corresponding cover panel 131. In this state, the displacement of the cover panel 131 is limited.

  For example, in the service plug 141, the engagement between the service plug main body 142 and the corresponding service plug grip 143 is released, and the service plug grip 143 is removed from the service plug main body 142, thereby fixing the cover fixed by the engagement. The panel 131 becomes movable.

  Specifically, the service plug main body 142 and the corresponding service plug grip 143 in the service plugs 141FW1 and 141FE1 are respectively disengaged, and the corresponding service plug grip 143 is removed to fix the service plug main body 142 and the corresponding service plug grip 143. The covered cover panel 131F1 becomes movable.

  Similarly, the service plug main body 142 and the corresponding service plug grip 143 in the service plugs 141RW1 and 141RE1 are respectively disengaged, and the corresponding service plug grip 143 is removed, thereby being fixed by the engagement. The cover panel 131R1 becomes movable.

  That is, for example, by disengaging the service plug main body 142 and the service plug grip 143 in the service plug 141, the service plug 141 releases the displacement of the corresponding cover panel 131, and the corresponding cover panel 131 The extraction space 311 can be opened.

  The service plug main body 142 in the service plugs 141FW2-141FW4, 141FE2-141FE4 is similar to the service plug main body 142 in the service plugs 141FW1, 141FE1, respectively, so that it can be engaged with the corresponding service plug grip 143, respectively. It is fixed to 201F4.

  In addition, the service plug main body 142 in the service plugs 141RW2 to 141RW4 and 141RE2 to 141RE4 can be engaged with the corresponding service plug grip 143 in the same manner as the service plug main body 142 in the service plugs 141RW1 and 141RE1, respectively. It is fixed to 201R2 to 201R4.

  In addition to the service plug 141, the cover panel 131 may be fixed to the general-purpose plate 201 using a fixing member such as a screw. Thereby, the cover panel 131 can be more reliably fixed to the general-purpose board 201.

Storage batteries B41 to B44 and service plugs 141RW4, 141RE4, 141FE4, and 141FW4 constitute a series unit BS4.

  More specifically, the service plugs 141RW1, 141RW2, 141RW3, and 141RW4 are respectively connected to the first end T1 connected to the first end, the second end, the third end, and the fourth end of the BMS 501, and the storage batteries B11, B21, A second end T2 connected to the anodes TP11, TP21, TP31, TP41 in B31, B41, a third end T3 connected to the cathodes TM11, TM21, TM31, TM41 in the storage batteries B11, B21, B31, B41, and And four ends T4.

  The service plugs 141RE1, 141RE2, 141RE3, 141RE4 are respectively connected to the first end T1 connected to the fourth end of the service plugs 141RW1, 141RW2, 141RW3, 141RW4, and the anodes TP12, TP22, It has the 2nd end T2 connected to TP32, TP42, the 3rd end T3 connected to cathode TM12, TM22, TM32, TM42 in storage battery B12, B22, B32, B42, and the 4th end T4.

  The service plugs 141FE1, 141FE2, 141FE3, and 141FE4 are respectively connected to the first end T1 connected to the fourth end of the service plugs 141RE1, 141RE2, 141RE3, and 141RE4, and the anodes TP13 and TP23 in the storage batteries B13, B23, B33, and B43. It has a second end T2 connected to TP33, TP43, a third end T3 connected to the cathodes TM13, TM23, TM33, TM43 in the storage batteries B13, B23, B33, B43, and a fourth end T4.

  The service plugs 141FW1, 141FW2, 141FW3, and 141FW4 are respectively connected to the first end T1 connected to the fourth end of the service plugs 141FE1, 141FE2, 141FE3, and 141FE4, and the anodes TP14 and TP24 in the storage batteries B14, B24, B34, and B44.

And four ends T4.

  That is, in the storage device 161, four series units BS1, BS2, BS3, BS4 are connected in parallel. Hereinafter, the serial units BS1, BS2, BS3, BS4 are also referred to as serial units BS.

  Further, in the service plug 141, when the service plug main body 142 and the service plug grip 143 are engaged, an electrical connection path between the storage batteries B placed on the corresponding shelf 121 and between the storage batteries B and the BMS 501. A part of is formed.

  On the other hand, in the service plug 141, in the state where the engagement of the service plug main body 142 and the service plug grip 143 is released, the electrical connection between the storage batteries B placed on the corresponding shelf 121 and between the storage batteries B and BMS501. Connection is not formed.

  For example, when a plurality of storage batteries B are connected in series, a high voltage is generated. Therefore, there is a possibility of an electric shock when an operator performs replacement work of the storage battery B.

  On the other hand, in the power supply device 101 according to the embodiment of the present invention, when the worker WM2 performs, for example, the replacement work of the storage battery B24, the service plug grip 143 in the service plugs 141FW2 and 141FE2 as shown in FIG. To remove the cover panel 131F2.

  Then, the worker WM2 extends the cover panel 131F2 toward the outside of the power supply apparatus 101, and moves the storage battery B24 from the placement surface 122 of the shelf 121S2 to the work surface 136 of the cover panel 131F2.

  That is, when the worker WM2 performs the replacement work of the storage battery B24, since the electrical connection between the storage battery B24 to be replaced and the other storage battery B or BMS 501 is disconnected, the worker WM2 It is possible to avoid an electric shock.

  Further, the storage battery B can be replaced without the operator WM2 operating the service plug 141 by providing the service plug 141 at a position where the operator WM2 can easily operate the service plug 141, specifically, the front and rear surfaces of the shelf 121. It is possible to avoid starting work.

  Further, in the service plug 141, the service plug 141 and the service plug grip 143 are engaged with each other while sandwiching the notch 133 of the cover panel 121, so that the service plug 141 can be installed at a lower cost than a service plug for an automobile, for example. Can be produced.

  In addition, although the power supply device 101 which concerns on embodiment of this invention was set as the structure containing serial unit BS1, BS2, BS3, BS4, it is not limited to this. The power supply apparatus 101 may be configured to include, for example, three or less or five or more series units BS.

  Moreover, although serial unit BS1, BS2, BS3, BS4 in the power supply device 101 which concerns on embodiment of this invention was set as the structure containing the four storage batteries B, respectively, it is not limited to this. Each series unit may be configured to include, for example, three or less or five or more storage batteries B.

  Moreover, although serial unit BS1, BS2, BS3, BS4 in the power supply device 101 which concerns on embodiment of this invention was set as the structure by which each serial unit is connected in parallel, it is not limited to this. A part or all of each series unit may be connected in series, for example.

  Further, the service plug 141 may include a fuse. Accordingly, it is possible to prevent the overcurrent from continuously flowing in the connection cable and to accommodate the fuse in a compact manner.

[Cover panel size]
FIG. 15 is a cross-sectional view of the power supply device according to the embodiment of the present invention as seen from above when the front door is opened.

  Referring to FIG. 15, double-open door 104 is attached to casing 102 in power supply device 101. The power supply device 101 may be provided with a single door.

  The opening / closing angle β of the door 104 is obtained, for example, by an angle formed by the opened door 104 and the extending direction S of the cover panel 131. The opening / closing angle β may be obtained, for example, by an angle formed by the opened door 104 and the front-rear direction of the side plate 222E or 222W.

  For example, the direction in which the opening / closing angle β is zero is the extending direction S or the front-rear direction of the side plate 222E or 222W. Further, the direction in which the door 104 that closes the opening 301 is opened is the increasing direction of the opening / closing angle β. That is, the opening / closing angle β when the door 104 closes the opening 301 is, for example, minus 90 degrees.

  Specifically, in FIG. 15, when the front door 104FW rotates clockwise, the opening / closing angle βFW increases. When the front door 104FW closes the opening 301F, the opening / closing angle βFW is approximately minus 90 degrees.

  In FIG. 15, when the front door 104FE rotates counterclockwise, the opening / closing angle βFE increases. When the front door 104FE closes the opening 301F, the opening / closing angle βFW is approximately minus 90 degrees.

  Further, since the doors 104FW and 104FE have interference with the drainer 103F, for example, the open / close angles βFW and βFE do not exceed substantially plus 90 degrees even in the fully opened state.

  For example, the opening / closing angles βFW and βFE are approximately plus 45 degrees when the doors 104FW and 104FE are fully opened, respectively. For example, the opening / closing angles βFW and βFE may be approximately plus 30 degrees when the doors 104FW and 104FE are fully opened, respectively. That is, the sizes of the open / close angles βFW and βFE are limited to be acute angles.

  For example, the workers WM2 and WM3 open the doors 104FW and 104FE, then extend the cover panel 131F1 toward the outside of the power supply apparatus 101, and place the storage battery B14 placed on the shelf 121S1 on the work surface 136 of the cover panel 131F1. Move to.

  The workers WM2 and WM3 move the storage battery B14 to the vicinity of the end on the side opposite to the side connected to the shelf 121 of the cover panel 131F1, and then take out the storage battery B14.

  For example, when the size of the cover panel 131F1 is large enough to allow the storage battery B14 to be placed, the workers WM2 and WM3 can secure a sufficient space for replacing the storage battery B14. Storage battery B14 can be easily taken out. When the hand lifter 951 can be used, the tip of the fork portion 952 can reach the vicinity of the storage battery B14, so that the storage battery B14 can be taken out more easily.

  Further, for example, when the cover panel 131 is in a fully open state, the length L from the outer end of the opening 301 to the end opposite to the side connected to the shelf 121 of the cover panel 131 is the door. When it is longer than half of the width WD of 104, the workers WM2 and WM3 can secure a sufficient space for exchanging the storage battery B14, and can easily take out the storage battery B14. When the hand lifter 951 can be used, the tip of the fork portion 952 can reach the vicinity of the storage battery B14, so that the storage battery B14 can be taken out more easily.

  In addition, for example, when the length L is longer than the width WD, the workers WM2 and WM3 can sufficiently secure a space for performing the replacement work of the storage battery B14, thereby increasing the efficiency of the replacement work of the storage battery B14. be able to. When the hand lifter 951 can be used, the tip of the fork portion 952 can reach the vicinity of the storage battery B14, so that the storage battery B14 can be taken out more easily.

  In the storage device according to the embodiment of the present invention, the storage device 161 is configured to include the six shelves 121 of the shelves 121S0 to 121S5, but is not limited thereto. The storage device 161 may be configured to include, for example, 5 or less or 7 or more shelves 121. For example, when the number of shelves 121 is one, the service plug 141 may be provided on a 19-inch general-purpose plate that can be directly fixed to the column 111 instead of the upper shelf 121.

[How to replace storage battery B]
FIG. 16 is a flowchart defining a method for replacing a storage battery in the power supply device according to the embodiment of the present invention.

  Referring to FIG. 16, first, worker WM2 opens door 104 of power supply apparatus 101 (step S102).

  Next, worker WM2 removes service plug grip 143 in service plug 141 (step S104).

  Next, the worker WM2 opens the take-out space 311 by operating the cover panel 131 from which the displacement restriction by the service plug 141 is released (step S106).

  Next, the worker WM2 removes the connection cables connected to the anode TP and the cathode TM of the storage battery B in the opened extraction space 311 (step S108).

  Next, the workers WM2 and WM3 release the fixing of the storage battery B to the shelf 121 and move the storage battery B placed on the shelf 121 onto the work surface 136 of the cover panel 131 (step S110).

  Next, the workers WM2 and WM3 take out the storage battery B on the work surface 136 from the power supply device 101 (step S112).

  By the way, when the replacement operation of the storage battery is performed in the cubicle type storage battery panel described in Patent Document 1, for example, the worker performs operations such as taking out the stored storage battery and installing the replacement storage battery. In general, since the storage battery is heavy, the replacement work may be difficult depending on the size and installation location of the cubicle type storage battery panel.

  For example, when the width of the cubicle type storage battery panel is narrow, a sufficient space for the operator to perform the replacement work of the storage battery cannot be secured, and the replacement work of the storage battery becomes difficult.

  On the other hand, in the storage device according to the embodiment of the present invention, the storage device 161 stores the storage battery B. The shelf 121 can be loaded with the storage battery B. The casing 102 accommodates the shelf 121 and is formed with an opening 301 that defines, together with the shelf 121, an extraction space 311 in which the storage battery B placed on the shelf 121 can be extracted to the outside. The cover panel 131 can close part or all of the take-out space 311 of the storage battery B placed on the shelf 121. The cover panel 131 extends in the direction S from the take-out space 311 to the outside of the storage device 161 in a state in which the take-out space 311 is opened, and forms substantially the same plane as the placement surface 122 of the shelf 121.

  With such a configuration, the placement surface 122 of the shelf 121 can be substantially expanded to the outside of the storage device 161 using the cover panel 131, so that the storage battery B placed on the shelf 121 is stored without being lifted. It can be moved to the outside of the device 161.

  Thereby, even if it is a case where the width | variety of the accommodating apparatus 161 is narrow, since the space for an operator to replace the storage battery B can be ensured, the replacement work of the storage battery B can be performed easily.

  Further, for example, by closing part or all of the take-out space 311 with the cover panel 131 except during the replacement work of the storage battery B, it is possible to reduce the chance that the operator will inadvertently contact the storage battery B. .

  In addition, for example, by using a general-purpose cubicle and a 19-inch rack as the casing 102 and the shelf 121, a general-purpose storage device 161 is produced instead of producing a dedicated storage device according to the type of the storage battery B. Therefore, it is possible to reduce the production cost of the storage device 161 at the time of small lot multi-product production.

  In addition, for example, when a plurality of storage batteries B are connected in series, a high voltage is generated, so that there is a possibility of an electric shock when an operator performs replacement work of the storage battery B.

  On the other hand, in the storage device according to the embodiment of the present invention, the service plug 141 can limit the displacement of the cover panel 131, and the storage battery B placed on the shelf 121 and another storage battery B or BMS 501 Forming part of the electrical connection path. In a state where the service plug 141 restricts the displacement of the cover panel 131, a connection path including the service plug 141 is formed, and the cover panel 131 closes the take-out space 311. In the state where the service plug 141 releases the restriction of the cover panel 131, the connection path is not formed, and the cover panel 131 can open the take-out space 311.

  As described above, when the service plug 141 releases the restriction on the cover panel 131, the connection path is cut and the removal space 311 can be opened by the cover panel 131, so that the removal space 311 is opened. The electrical connection path between the storage battery B placed on the shelf 121 and another storage battery B or BMS 501 can be cut off.

  As a result, when the operator performs replacement work of the storage battery B, the electrical connection path can be reliably cut off and no high voltage is generated. Can be avoided.

  Further, in a state where the service plug 141 restricts the displacement of the cover panel 131, the connection path is conducted and the take-out space 311 is closed by the cover panel 131. Therefore, in a state where a high voltage is generated, Opportunities for the operator to inadvertently contact the anode TP, the cathode TM, etc. of the storage battery B can be reduced. Thereby, it can avoid that an operator is electrocuted by a high voltage.

  Moreover, in the storage device according to the embodiment of the present invention, the door 104 is attached to the casing 102 and can close the opening 301 of the casing 102. The opening of the door 104 is limited so that the angle β formed by the opened door 104 and the extending direction S of the cover panel 131 is an acute angle.

  As described above, the angle β formed by the opened door 104 and the extending direction S of the cover panel 131 is limited to be an acute angle, thereby limiting the work space for the operator to perform the replacement work of the storage battery B. Even in such a case, the placement surface of the shelf 121 can be substantially expanded to the outside of the storage device 161 in a state where the take-out space 311 is opened, so that the work space can be substantially expanded.

  Further, in the storage device according to the embodiment of the present invention, the friction coefficient of a part or all of the work surface 136 of the cover panel 131 that forms substantially the same plane as the placement surface 122 in a state where the take-out space 311 is opened is It is smaller than the friction coefficient of the mounting surface 122.

  With such a configuration, the heavy storage battery B can be slid on the work surface 136 in a state where the take-out space 311 is opened. Thereby, since the storage battery B can be easily moved on the work surface 136, the efficiency of the replacement work of the storage battery B can be improved.

  Further, in the storage device according to the embodiment of the present invention, the insulation of a part or all of the work surface 136 of the cover panel 131 that forms substantially the same plane as the placement surface 122 in a state where the extraction space 311 is opened is It is higher than the insulating property of the mounting surface 122.

  With such a configuration, in the state where the storage battery B is on the mounting surface 122 or the work surface 136 of the cover panel 131, the insulation between the anode TP and the cathode TM of the storage battery B can be made more reliable. And the occurrence of electric shock can be suppressed.

  Moreover, in the storage device according to the embodiment of the present invention, the size of the cover panel 131 is a size that allows the storage battery B to be placed in a state where the take-out space 311 is opened.

  With such a configuration, since the storage battery B can be moved from the end of the shelf 121 to the outside of the storage device 161 by the size of the storage battery B, the operator can replace the storage battery B from the outside of the storage device 161. A sufficient space can be ensured, and the storage battery B can be easily taken out.

  In the storage device according to the embodiment of the present invention, the stay 151 and the cover panel hinge 135 displace the cover panel 131 so that the cover panel 131 can open and close the extraction space 311. The stay 151 and the cover panel hinge 135 are attached to the shelf 121 and the cover panel 131.

  With such a configuration, the stay 151 and the cover panel hinge 135 and the shelf 121 and the cover panel 131 can be integrated before the storage device 161 is shipped as a product, so that the storage device 161 can be installed on site. Assembling property can be improved and versatility of the shelf 121 can be improved.

  In the storage device according to the embodiment of the present invention, it is recommended that a plurality of people take out the storage battery B placed on the shelf 121.

  Thus, even when it is recommended that a plurality of people take out the storage battery B placed on the shelf 121, the placement surface of the shelf 121 is substantially stored in the state where the removal space 311 is opened. 161 can be spread to the outside of 161, for example, the workers WM2 and WM3 can easily replace the storage battery B.

  In the storage device according to the embodiment of the present invention, the cover panel 131 is connected to the front side and the rear side of the storage device 161 in each shelf 121. However, the present invention is not limited to this. In each shelf 121, for example, the cover panel 131 may be connected to either the front side or the rear side. For example, when an opening is formed in at least one of the right side plate 222E and the left side 222W, in each shelf 121, the cover panel 131 is provided on at least one of the right side and the left side in addition to the front side and the rear side. The structure connected may be sufficient.

  In the storage device according to the embodiment of the present invention, the cover panel 131 is configured to close the entire take-out space 311, but is not limited thereto. The cover panel 131 may be configured to close a part of the take-out space 311, for example.

  In the storage device according to the embodiment of the present invention, in the state where the take-out space 311 is opened, the end of the cover panel 131 opposite to the side connected to the shelf 121 is the end face on the outside of the opening 301. Although the configuration is more outward, the present invention is not limited to this. For example, when the shelf 121 is in the back of the casing 102, the cover panel 131 has an end on the opposite side to the side connected to the shelf 121 of the cover panel 131 even when the take-out space 311 is opened. The outer end surface of the casing 102, more specifically, the outer end surface of the drainer 103 may be accommodated inside.

  Further, in the storage device according to the embodiment of the present invention, the storage battery B included in the take-out space 311 where the cover panel 131 that restricts the displacement of the service plug 141 opens and closes, and the service plug 141 is electrically connected and disconnected. Although it was set as the structure used as the object storage battery B, it is not limited to this. For example, the storage battery B included in the take-out space 311 where the cover panel 131 that restricts the displacement of the service plug 141 opens and closes and the storage battery B that the service plug 141 is an object of electrical connection and disconnection may be different. .

  Specifically, for example, when the storage battery B included in the take-out space 311 where the cover panel 131 opens and closes as described above and the storage battery B to be moved onto the work surface 136 of the cover panel 131 are different, the service plug 141 The storage battery B to be electrically connected and disconnected may be the storage battery B included in the take-out space 311 where the cover panel 131 whose displacement is limited by the service plug 141 is opened or closed. The storage battery B to be moved onto the work surface 136 may be used.

  In the storage device according to the embodiment of the present invention, when the cover panel 131 is closed, the length from the upper end to the lower end of the cover panel 131 is shorter than the interval between the shelves 121. However, the present invention is not limited to this. The length from the upper end to the lower end of the cover panel 131 may be longer than the interval between the shelves 121, for example. In this case, when the cover panels 131 of the upper and lower shelves 121 are closed, the cover panels 131 are partially overlapped.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
