Therefore, the chance that an operator will contact a high voltage terminal can be reduced.

  Further, since the length of the cable between the shelves can be adjusted to the length corresponding to the interval between the shelves, the specifications of the cable between the shelves can be unified. Thereby, the manufacturing cost of the cable between shelves and the man-hour of wiring work can be reduced.

  (3) Preferably, a plurality of storage batteries can be placed on the shelf, and the battery connection cable is for electrically connecting between the storage batteries corresponding to the same shelf or the storage battery and another circuit. In-shelf cables are included.

  With such a configuration, the wiring of the in-shelf cable in the shelf can be changed to a wiring according to the spatial arrangement of the shelf and the storage battery. Thereby, between storage batteries corresponding to the same shelf, or a storage battery and another circuit can be efficiently wired using the cable in a shelf.

  In addition, for example, when the cable attachment portion has a role other than the purpose of attaching the battery connection cable to the shelf, the number of parts attached to the periphery of the shelf can be reduced, and the space around the shelf can be reduced. It can be used effectively.

  (6) Preferably, the storage device further includes a storage battery fixing portion that can be fixed by sandwiching the storage battery placed on the shelf and can change the size of the storage battery to be fixed by being displaced.

  Thereby, for example, when designing storage devices having different specifications with respect to electrical connection, it is possible to share a mechanism design other than electrical connection. And the storage apparatus from which the specification of electrical connection differs can be designed by changing the connection of the cable in a shelf and the cable between shelves. Therefore, design cost and manufacturing cost can be reduced.

Thereby, the specification of a shelf can be unified.

  In addition, strength for placing a heavy storage battery is required, and instead of processing or manufacturing a heavy shelf, it is only necessary to process or manufacture a low-strength and lightweight panel. Thus, the manufacturing cost can be reduced and the workability can be improved.

[Power storage system]
FIG. 1 is a diagram showing a configuration of a power storage system according to the first 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 is charged with DC power received from the bidirectional converter circuit 534 in the power conditioner 512 via the charging / discharging cable 135 according to the voltage between the anode TP and the cathode TM of each storage battery B. The energy stored in the storage battery B is discharged as DC power to the bidirectional converter circuit 534 via the charge / discharge cable 135.

Thereby, since the length of the battery connection cable 132M1b can be shortened, the impedance of the battery connection cable 132M1b can be lowered to reduce the power loss, and the manufacturing cost can be lowered.

[Battery connection cable impedance]
As shown in FIG. 6, each shelf 121 is configured with, for example, the same type of electric wires and has substantially the same length, and specifically, battery connection cables 131, 133, 134, 145, and 146. Is attached. Therefore, the impedance of the path formed by the in-shelf cable from the terminal T13 in the inter-shelf terminal block 161 to the terminal T12 in the inter-shelf terminal block 161 via the storage battery B is substantially the same for each shelf 121.

  As shown in FIG. 3, between the shelves 121, for example, an inter-shelf cable configured with the same kind of electric wires and having substantially the same length is attached. Accordingly, the impedance between the terminal T23 in the inter-shelf terminal block 161C1 and the terminal T23 in the inter-shelf terminal block 161C2, and the impedance between the terminal T22 in the inter-shelf terminal block 161C1 and the terminal T22 in the inter-shelf terminal block 161C2 are substantially the same. .

  The impedance between the terminal T23 in the inter-shelf terminal block 161C and the terminal T23 in the inter-shelf terminal block 161C3, and the impedance between the terminal T22 in the inter-shelf terminal block 161C2 and the terminal T22 in the inter-shelf terminal block 161C3 are substantially the same.

  The impedance between the terminal T23 in the inter-shelf terminal block 161C3 and the terminal T23 in the inter-shelf terminal block 161C4, and the impedance between the terminal T22 in the inter-shelf terminal block 161C3 and the terminal T22 in the inter-shelf terminal block 161C4 are substantially the same.

  In addition, the impedance between the terminals T23 and T13 and between the terminals T12 and T22 in each of the inter-shelf terminal blocks 161C1 to 161C4 is small enough to be ignored.

  Therefore, the impedance of each path formed by the battery connection cable from the device terminal block 162 which is a connection portion between the power supply device 101 and the BMS 501 to the device terminal block 162 via the storage battery B placed on each shelf 121 is substantially equal. The same.

  More specifically, the impedance of each path formed by the battery connection cable from the terminal T31 in the device terminal block 162 to the terminal T32 in the device terminal block 162 via each of the series units BS1 to BS4 is substantially the same.

  Thereby, when charging or discharging the storage battery B in the series units BS <b> 1 to BS <b> 4, substantially the same voltage can be applied to or output from any storage battery B, so that the life of the storage battery B can be extended. .

[Method for Manufacturing Power Supply Device]
FIG. 10 is a flowchart defining the method for manufacturing the power supply device according to the first embodiment of the present invention.

  Referring to FIG. 10, first, the manufacturer attaches battery connection cables including in-shelf cables and inter-shelf cables to shelves 121 in a factory, for example (step S102).

  Next, the manufacturer fixes the shelf 121 to which the battery connection cable is attached to the 19-inch rack fixed to the casing 102 (step S104).

  Next, the manufacturer ships the storage device 151 and the storage battery B in a state where the storage battery B is not placed on the shelf 121 (step S106).

  Next, the manufacturer installs the storage device 151 in the office or the like in a state where the storage battery B is not placed on the shelf 121 (step S108).

  Next, the manufacturer places the storage battery B on the shelf 121 in the storage device 151 (step S110).

  Next, the manufacturer connects the battery connection cable attached to the shelf 121 to the storage battery B placed on the shelf 121 (step S112).

  In step S102 and step S104, the storage device 151 is manufactured. In steps S106 and S108, the storage device 151 is installed. In steps S110 and S112, the storage battery 151 is stored in the storage device 151, and the power supply apparatus 101 is installed by connecting the storage battery B.

  Further, when the storage battery 151 that is a heavy object is transported in the state where the storage battery B is placed on the shelf 121, the storage device 151 is required to have a considerable strength. In the above method, in step S106, after the storage device 151 in a state where the storage battery B is not placed on the shelf 121 is shipped, the storage battery B is placed on the shelf 121 in the storage device 151, thereby achieving a considerable strength. There is no need to manufacture the storage device 151 with increased strength, and the storage device 151 can be reduced in weight and cost.

  In addition, in said step S102, the cable in a shelf and the cable between shelves were attached to the shelf 121, However, It is not limited to this. Since the intra-shelf cable and the inter-shelf cable are detachable from the shelf 121, the cable is shipped in step S106 with either one of the intra-shelf cable or the inter-shelf cable attached to the shelf 121 in step S102. Also good. Then, in the site where the storage device 151 is installed, an intra-shelf cable or an inter-shelf cable that was not attached before shipment may be attached to the shelf 121.

  The storage device 151 may be shipped in a state in which a part of the shelf 121, a part of the cable in the shelf, or a part of the cable between the shelves is removed from the storage device 151.

  The in-shelf cable in the storage device 151 is configured to be connected to the storage battery B placed on the shelf 121 one step below the shelf 121 to which the in-shelf cable is attached. It is not a thing. For example, the in-shelf cable may be configured to be connected to the storage battery B placed on the shelf 121 to which the in-shelf cable is attached.

  By the way, in the storage battery storage cubicle described in Patent Document 1, since the terminals of a plurality of storage batteries are arranged on the same surface, it is difficult to grasp which storage battery terminals should be connected to each other. For this reason, an operator may make an incorrect connection when connecting the terminals of the storage battery.

  In addition, for example, when the storage batteries in the storage box are electrically connected in series, when the worker electrically connects the storage boxes, the worker comes into contact with a high-voltage terminal and receives an electric shock. There is a case.

  On the other hand, in the storage device according to the first embodiment of the present invention, the storage device 151 is the storage device 151 of the storage battery B, on which the storage battery B can be placed, and the storage battery B can be stored. A plurality of shelves 121 provided at intervals are provided, and battery connection cables 131, 132, 133, 134, 145, and 146 for electrically connecting the storage battery B and another storage battery B or BMS 501 are provided. The battery connection cables 131, 132, 133, 134, 145, and 146 are attached to the shelf 121 in a state where the storage battery B is not placed on the shelf 121.

  With such a configuration, after the storage device 151 is installed, the storage battery B is placed on the shelf 121, and the battery connection cables 131, 132, 133, 134, 145 attached to the shelf 121 during the manufacturing process of the storage device 151. , 146 and storage battery B are connected to complete the connection work, so that the connection work can be simplified and the storage battery can be connected correctly.

  In addition, since the connection work between the battery connection cables 131, 132, 133, 134, 145, and 146 can be completed before the storage battery B is placed on the shelf 121, the operator can come into contact with a high voltage terminal. Can reduce the chances. Thereby, a storage battery can be connected correctly and it can avoid that an operator gets an electric shock by a high voltage.

  Further, when the storage battery 151 that is a heavy object is transported in the state where the storage battery B is placed on the shelf 121, the storage device 151 is required to have a considerable strength. In the above configuration, after the storage device 151 in a state where the storage battery B is not placed on the shelf 121 is installed, the storage battery B is placed on the shelf 121 in the storage device 151, thereby increasing the strength to a considerable strength. It is not necessary to manufacture the device 151, and the storage device 151 can be reduced in weight and cost.

  Further, for example, by using a general-purpose cubicle and a 19-inch rack as the casing 102 and the shelf 121, respectively, a general-purpose storage device 151 is produced instead of 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 151 at the time of producing a small lot and a variety of products.

  Moreover, in the storage apparatus which concerns on the 1st Embodiment of this invention, the cable between shelves for electrically connecting the storage battery B and the storage battery B mounted in the other shelf 121 is connected to the battery connection cable 132. Is included.

  With such a configuration, for example, when the storage batteries B are connected in series, terminals that can generate a high voltage are connected to each other using the inter-shelf cable before the storage battery B is placed on the shelf 121. Therefore, the opportunity for the operator to come into contact with a high voltage terminal can be reduced.

  Moreover, since the length of the cable between shelves can be equalized with the length according to the space | interval of the shelf 121, the specification of the cable between shelves can be unified. Thereby, the manufacturing cost of the cable between shelves and the man-hour of wiring work can be reduced.

  Further, in the storage device according to the first embodiment of the present invention, the shelf 121 can be loaded with a plurality of storage batteries B, and the storage device 151 is between the storage batteries B corresponding to the same shelf 121 or the storage battery B and others. Battery connection cables 131, 133, 134, 145, and 146, which are in-shelf cables for electrically connecting these circuits.

  With such a configuration, the wiring of the intra-shelf cable in the shelf 121 can be changed to a wiring according to the spatial arrangement of the shelf 121 and the storage battery B. Thereby, between the storage batteries B corresponding to the same shelf 121, or the storage battery B and another circuit can be efficiently wired using the cable in a shelf.

  Further, for example, when the shelf 121 to which the in-shelf cable is attached is made common, the specifications of the in-shelf cable can be unified, thereby reducing the manufacturing cost of the in-shelf cable and the man-hours of the wiring work. Can do.

  In the storage device according to the first embodiment of the present invention, the inter-shelf terminal block 161, the wire clip 163, the connector base 141, the connector insertion portion 142, and the relay terminal block 144 have the storage battery B on the shelf 121. The battery is fixed to the shelf 121 in a state where it is not placed, and the battery connection cable is attached to the shelf 121.

  As described above, the shelf 121 and the battery connection cable are fixed to the shelf 121 using the inter-shelf terminal block 161, the wire clip 163, the connector base portion 141, the connector insertion portion 142, and the relay terminal block 144, for example, battery connection Even when the wiring of the cable is changed, the specification can be changed by changing the arrangement of the inter-shelf terminal block 161, the wire clip 163, the connector base portion 141, the connector insertion portion 142, or the relay terminal block 144. It can respond flexibly to this.

  In addition, for example, the inter-shelf terminal block 161, the connector base 141, the connector insertion portion 142, and the relay terminal block 144 have a role other than the purpose of attaching the battery connection cable to the shelf 121. The number of parts attached to the rack can be reduced, and the space around the shelf 121 can be effectively utilized.

  Moreover, in the storage device according to the first embodiment of the present invention, the shelf 121 can be loaded with a plurality of storage batteries B, and the battery connection cables 131, 132, 133, 134, 145, and 146 have the same shelf. The battery connection cables 131, 133, 134, 145, and 146, which are in-shelf cables for electrically connecting the storage batteries B corresponding to 121 or between the storage batteries B and other circuits, and the storage batteries B and the other shelves 121 An inter-shelf cable for electrically connecting the storage battery B to be placed is included. The in-shelf cable is provided to electrically connect a plurality of storage batteries B placed on the shelf 121 in series. The inter-shelf cable is provided to electrically connect the storage battery B placed on the shelf 121 and the storage battery B placed on the other shelf 121 in parallel.

  With such a configuration, since the electrical connection between the storage batteries B placed on different shelves 121 can be associated with the spatial arrangement of these shelves 121, each storage battery B in the storage device 151 can be associated with each other. It is possible to intuitively determine the set of storage batteries B placed on each shelf 121 as one unit without considering the electrical connection in units of individual storage batteries B.

  Thereby, for example, when designing storage devices 151 having different specifications for electrical connection, mechanism design other than electrical connection can be made common. And the storage apparatus 151 from which the specification of an electrical connection differs can be designed by changing the connection of the cable in a shelf and the cable between shelves. Therefore, design cost and manufacturing cost can be reduced.

  Moreover, in the storage device according to the first embodiment of the present invention, the shelf 121 can be loaded with a plurality of storage batteries B. Battery connection cables 131, 132, 133, 134, 145, and 146 are battery connection cables that are in-shelf cables for electrically connecting the storage batteries B corresponding to the same shelf 121 or between the storage batteries B and other circuits. 131, 133, 134, 145, 146 are included. For the connection target of the in-shelf cable, the storage battery B placed on the shelf 121 to which the in-shelf cable is attached, or the storage battery B to be placed on the shelf 121 one step below the shelf 121 to which the in-shelf cable is attached. Is included.

  With such a configuration, wiring of the storage battery B using the in-shelf cable can be easily performed based on the spatial arrangement of the shelf 121 and the storage battery B.

  Further, since the storage battery B to be connected to the in-shelf cable is located near the shelf 121 to which the in-shelf cable is attached, the in-shelf cable can be shortened. Thereby, while reducing the impedance of the cable in a shelf and reducing a power loss, manufacturing cost can be reduced.

  In the storage device according to the first embodiment of the present invention, the connector base 141, the relay terminal block 144, the terminal designation label 171 and the shelf 121 are connected to the battery connection cables 131, 132, 133, 134, 145, 146. It has the identifier which shows the terminal of the storage battery B used as a connection destination.

  With such a configuration, in the connection work, the operator can easily recognize the terminal of the storage battery B to which the battery connection cables 131, 132, 133, 134, 145, and 146 are connected. The connection can be made more correctly.

  Moreover, in the storage device according to the first embodiment of the present invention, the connector base 141, the connector plug 142, and the relay terminal block 144 are connected to the terminals of the storage battery B at the ends of the battery connection cables 145, 146. The opposite end of the part is connected. The connector base 141, the connector insertion part 142, and the relay terminal block 144 are provided at positions corresponding to the positions of the terminals of the storage battery B.

  With such a configuration, in the connection work, the operator can easily determine the storage battery B to be connected to the battery connection cables 145 and 146.

  Moreover, in the storage device according to the first embodiment of the present invention, the panel 201 with connector and the panel 201m with terminal block are detachable from the shelf 121, and are connected to the battery connection cables 131, 133, 145, 146. The connected connector base 141, connector insertion part 142, and relay terminal block 144 are attached.

  With such a configuration, for example, even when the type and arrangement of the storage battery B placed on the shelf 121 are changed, it is possible to cope by separately manufacturing the panel 201 with a connector and the panel 201m with a terminal block. Therefore, the same shelf 121 can be used as it is. Thereby, the specification of the shelf 121 can be unified.

  In addition, the strength of the storage battery B, which is a heavy object, is required, and instead of processing or manufacturing the shelf 121, which is a heavy object, the panel 201 with a connector and the terminal block that are low in strength and light in weight are required. Since the attached panel 201m may be processed or manufactured, the manufacturing cost can be reduced and workability can be improved.

  In the storage device according to the first embodiment of the present invention, the power supply device 101 is mounted on each shelf 121 from the terminal T31 in the device terminal block 162 that is a connection portion with the BMS 501 that is an external circuit of the power supply device 101. The impedance of each path by the battery connection cable to the terminal T32 in the device terminal block 162 via the storage battery B to be placed is substantially the same.

  With such a configuration, for example, when charging or discharging the storage battery B placed on each shelf 121, substantially the same voltage can be applied to or output from any storage battery B. Therefore, the storage battery B Can extend the lifespan.

  In the storage device according to the first embodiment of the present invention, the battery connection cable is configured to use the terminal block and the connector for connecting the terminals of the cable. However, the present invention is not limited to this. The terminals of the cable may be electrically and physically connected by a method such as fitting, crimping, and bonding.

  Further, in the storage device according to the first embodiment of the present invention, the in-shelf cable and the BMS 501 are configured to be electrically connected via the device terminal block 162 which is a connection portion.

<Second Embodiment>
The present embodiment relates to a storage device including a shelf to which a fuse is fixed as compared with the storage device according to the first embodiment. The contents other than those described below are the same as those of the storage device according to the first embodiment.

[Composition of shelf]
FIG. 11: is the bottom view which looked at the shelf based on the 2nd Embodiment of this invention from the lower side.
FIG. 12 is a perspective view of the shelf shown in FIG. 11 viewed from the right side when the storage battery is placed.

  A shelf 121S0 is representatively shown in FIGS. The shelf 121S1 (not shown) and the shelf 121S2 to 121S5 (not shown) are the same as the shelf 121S0 shown in FIGS.

  Referring to FIG. 11, storage device 151 has battery connection cables 131Pf1 and 131Pg1 and fuses instead of battery connection cable 131Pb1 and connector-equipped panel 201F0 for shelf 121S0, as compared with the storage device according to the first embodiment. A panel 201fF0 is provided, and a fuse 143F1 is further provided. In addition, the storage device 151 is different from the storage device according to the first embodiment in that the battery connection cables 131Pf2 to 131Pf4 are used instead of the battery connection cables 131Pb2 to 131Pb4 and the panels 201F1 to 201F3 with connectors for the shelves 121S1 to 121S3. , 131Pg2 to 131Pg4 and panels 201fF1 to 201fF3 with fuses, and further, fuses 143F2 to 143F4.

  Hereinafter, each of the battery connection cables 131Pa1 to 131Pa4, 131Pc1 to 131Pc4, 131Pd1 to 131Pd4, 131Pe1 to 131Pe4, 131Pf1 to 131Pf4, 131Pg1 to 131Pg4 is also referred to as a battery connection cable 136. Each of the panels 201fF0 to 201fF3 with a fuse is also referred to as a panel 201f with a fuse. Each of fuses 143F1 to 143F4 is also referred to as fuse 143.

  Battery connection cables 136 and 145 are provided to electrically connect storage battery B and another circuit, for example. Specifically, the battery connection cables 136 and 145 are in-shelf cables, and are provided, for example, to electrically connect the storage batteries B corresponding to the same shelf 121 or the storage battery B and another circuit. Other circuits include, for example, the storage battery B, the connector base 141, the connector insertion part 142, the inter-shelf terminal block 161, and the fuse 143.

[Installation of shelf cables and fuses on the shelf]
For example, fuse-equipped panels 201fF0 to 201fF3 are detachably fixed to the shelves 121S0 to 121S3, respectively. Specifically, as shown in part in FIG. 12, the front surfaces of the shelves 121S0, 121S1, 121S2, and 121S3 are fused with panel fixing screws 202F01 to 202F04, 202F11 to 202F14, 202F21 to 202F24, and 202F31 to 202F34, respectively. Panels 201fF0, 201fF1, 201fF2, and 201fF3 are fixed to be removable.

  In the storage device 151 in a state where the storage battery B is not placed on the shelf 121, the fuse 143 is fixed to the shelf 121 via a panel 201f with a fuse, for example.

  Specifically, the fuse 143 is detachably fixed to the panel 201 with a connector by, for example, bolts and nuts. For example, the fuse 143 is fixed to the approximate center of the panel 201f with a fuse.

  In the storage device 151 in a state where the storage battery B is not placed on the shelf 121, the battery connection cable 136 is attached to the shelf 121, for example. Specifically, the fuse 143 attaches the battery connection cable 136 to the panel 201f with a fuse, for example. More specifically, as shown in FIG. 11, in the shelf 121S0, the battery connection cable 131Pf1 is connected to the first end connected to the second pole of the connector base 141FW1, and the first of the fuses 143 is detachable using, for example, screws.

  The battery connection cable 131Pg1 has a first end connected to the second end of the fuse 143 so as to be detachable using, for example, screws, and a second end connected to the first pole of the connector base 141FE1.

  The fuse 143 conducts between the first end and the second end when a current smaller than the rating flows between the first end and the second end. Further, the fuse 143 is blown when a current exceeding the rating flows between the first end and the second end. Thereby, since the first end and the second end are electrically disconnected, the battery connection cable, the storage battery B, and the like can be protected from a current exceeding the rating.

  In the storage device according to the second embodiment of the present invention, the fuse 143 is configured to be fixed to the shelf 121 via the panel 201f with a fuse. However, the present invention is not limited to this. For example, the fuse 143 may be configured to be directly fixed to the shelf 121.

  Moreover, although the fuse 143 according to the second embodiment of the present invention is configured to be connected to the connector base 141 via the battery connection cable 136, the present invention is not limited to this. For example, the fuse 143 may be configured to be connected to the relay terminal block 144 via the battery connection cable 133. Moreover, the structure connected to the battery connection cable 134 may be sufficient as the fuse 143, for example.

  In addition, the fuse 143 according to the second embodiment of the present invention is configured to be attached to the approximate center of the panel 201f with a fuse. However, the present invention is not limited to this. The fuse 143 may be attached to another position of the panel 201f with a fuse.

[Electrical connection of fuse and battery connection cable]
FIG. 13 is a diagram illustrating an example of electrical connection of the storage battery according to the second embodiment of the present invention.

  Referring to FIG. 13, in storage device 151, for example, fuse 143 is connected in series with storage battery B in series unit BS in the state where the cable in the shelf, the cable between shelves, storage battery B, and the connection portion are electrically connected. Is done.

  Specifically, in the electrical connection of the storage battery B shown in FIG. 13, the storage batteries B13, B23, B33, B43 and the storage batteries B14, B24, B34, B44 are compared with the electrical connection of the storage battery B shown in FIG. The fuses 143F1, 143F2, 143F3, and 143F4 are respectively connected between them.

  More specifically, the second ends of fuses 143F1, 143F2, 143F3, and 143F4 are electrically connected to cathodes TM13, TM23, TM33, and TM43 in storage batteries B13, B23, B33, and B43, respectively.

  First ends of fuses 143F1, 143F2, 143F3, and 143F4 are electrically connected to anodes TP14, TP24, TP34, and TP44 in storage batteries B14, B24, B34, and B44, respectively.

  The fuses 143F1, 143F2, 143F3, 143F4 according to the second embodiment of the present invention are connected between the storage batteries B13, B23, B33, B43 and the storage batteries B14, B24, B34, B44, respectively. Although there is, it is not limited to this. For example, the fuse 143 may be connected in series with a circuit connected to the in-shelf cable.

  In the storage device 151 according to the second embodiment of the present invention, one fuse 143 is connected to each shelf 121. However, the present invention is not limited to this. For example, the storage device 151 may have a configuration in which a plurality of fuses 143 are connected to each shelf 121.

  Since other configurations and operations are the same as those of the storage device according to the first embodiment, detailed description thereof will not be repeated here.

  For example, in a power supply device, fuses may be installed together in one place. In this case, since it is necessary to wire the battery connection cable to the place where the fuse is installed, the battery connection cable becomes long and the wiring of the battery connection cable may be complicated.

  On the other hand, in the storage device according to the second embodiment of the present invention, the fuse 143 is fixed to the shelf 121 in a state where the storage battery B is not placed on the shelf 121, and corresponds to the same shelf 121. Connected between.

  With such a configuration, the fuse installation work at the site where the storage device 151 is installed can be made unnecessary, and the number of man-hours at the site can be reduced.

  Further, since the fuse 143 can be fixed at an appropriate position corresponding to the circuit to which the fuse 143 is connected, for example, a shorter battery connection cable than a case where a plurality of fuses 143 are installed in one place. It is possible to perform simple wiring using the circuit, and it is possible to easily recognize the correspondence between the fuse 143 and the circuit.

  In addition, since the fuse 143 is blown when a current exceeding the rating flows, the battery connection cable and the circuit can be protected from the current exceeding the rating.

  Moreover, in the storage device according to the second embodiment of the present invention, the panel 201f with fuse is detachable from the shelf 121, and includes a connector base 141 connected to the battery connection cables 136 and 145, and a connector plug-in. The part 142 and the fuse 143 are attached.

  With such a configuration, for example, even when the type and arrangement of the storage batteries B placed on the shelf 121 are changed, it is possible to cope by separately manufacturing the panel 201f with a fuse. Can be used as is. Thereby, the specification of the shelf 121 can be unified.

  Further, strength for placing the heavy storage battery B is required, and instead of processing or manufacturing the heavy load shelf 121, a required low strength and lightweight panel 201f with a fuse is processed or Since it only has to be manufactured, the manufacturing cost can be reduced and the workability can be improved.

  Next, another embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

<Third Embodiment>
The present embodiment relates to a storage device that has an improved function of fixing a storage battery placed on a shelf as compared with the storage device according to the first embodiment. The contents other than those described below are the same as those of the storage device according to the first embodiment.

FIG. 14: is the perspective view which looked at an example of the shelf which concerns on the 3rd Embodiment of this invention from the left side surface side at the time of storage battery mounting.
FIG. 15 is a plan view of the shelf shown in FIG. 14 as viewed from above.
FIG. 16 is a bottom view of the shelf shown in FIG. 14 as viewed from below.

  FIG. 14 representatively shows two storage batteries B placed on the shelf 125S1. 14 to 16, the shelf 125S1 is shown, but the shelves 125S2 to 125S4 are the same as the shelf 125S1.

  Referring to FIG. 15, the storage device 151 includes a shelf (storage battery fixing unit) 125S1 instead of the shelf 121S1 and the fixing belts 165FW1, 165RW1, 165FE1, 165RE1, as compared with the storage device according to the first embodiment. In addition, battery fixing members (storage battery fixing portions) 231J11 to 231J14 and position fixing members (storage battery fixing portions) 241F11 to 241F14, 241C11 to 241C14, 241R11 to 241R14 are provided.

  Compared to the storage device according to the first embodiment, the storage device 151 includes a shelf (storage battery fixing unit) instead of the shelves 121S2 to 121S4 and the fixing belts 165FW2 to 165FW4, 165RW2 to 165RW4, 165FE2 to 165FE4, 165RE2 to 165RE4. ) 125S2 to 125S4, battery fixing members (storage battery fixing portions) 231J21 to 231J24, 231J31 to 231J34, 231J41 to 231J44, position fixing members (storage battery fixing portions) 241F21 to 241F24, 241F31 to 241F34, 241F41 to 241F44, 241C21 to 241C24, 241C31 to 241C34, 241C41 to 241C44, 241R21 to 241R24, 241R31 to 241R34, 241R41 to 241R4 Provided with a door.

  Guide holes 126F1 to 126F4, 126C1 to 126C4, and 126R1 to 126R4 are formed in the shelves 125S1 to 125S4, respectively.

  Hereinafter, each of the battery fixing members 231J11 to 231J14, 231J21 to 231J24, 231J31 to 231J34, and 231J41 to 231J44 is also referred to as a battery fixing member 231. Position fixing member 241F11 to 241F14, 241F21 to 241F24, 241F31 to 241F34, 241F41 to 241F44, 241C11 to 241C14, 241C21 to 241C24, 241C31 to 241C34, 241C41 to 241R241, 241R141, 241R14, 241R14, 241R14, 241R14 Each of these is also referred to as a position fixing member 241. Each of the guide holes 126F1 to 126F4 is also referred to as a guide hole 126F. Each of the guide holes 126C1 to 126C4 is also referred to as a guide hole 126C. Each of the guide holes 126R1 to 126R4 is also referred to as a guide hole 126R.

  14 to 16, in order to facilitate understanding of the structure of the shelf 125, the battery fixing member 231 and the position fixing member 241, and the positions of the guide holes 126F, 126C, 126R, the inter-shelf terminal block 161, the battery connection The cables 131 and 145, the connector insertion part 142, the wire clip 163, the crossing plate 224, and a part of the storage battery B placed on the shelf are not shown.

  For example, the connectors-attached panels 201F1 and 212R1 are detachably fixed to the shelf 125S1. More specifically, the connector-attached panel 201F1 is detachably fixed to the front surface of the shelf 125S1 by panel fixing screws 202F11 to 202F14. A panel 201R1 with a connector is detachably fixed to the rear surface of the shelf 125S1 by panel fixing screws 202R11 to 202R14.

  For example, the position fixing member 241 fixes the battery fixing member 231 to the shelf 125 so as to be displaceable. Specifically, the position fixing member 241 is, for example, a bolt with a washer. For example, the position fixing member 241 is configured to fix the battery by screwing the bolt of the position fixing member 241 with the battery fixing member 231 in a state where the shelf 125 is sandwiched between the washer of the position fixing member 241 and the battery fixing member 231. The member 231 is fixed to the shelf 125.

  On the front side and the rear side of the shelf 125, the guide holes 126F and 126R are long holes that are long in the left-right direction. The guide hole 126C is formed between the guide holes 126F and 126R in the shelf 125 and is a long hole that is long in the left-right direction.

  Specifically, the length of the guide holes 126F and 126R in the left-right direction is longer than the length corresponding to twice the length of one side of the storage battery B, for example. The length in the left-right direction of the guide hole 126C is longer than the length in the left-right direction of the guide holes 126F, 126R, for example.

  The width of the guide holes 126F and 126R in the front-rear direction is, for example, wider than the outer diameter of the bolt of the position fixing member 241 and narrower than the length of one side of the washer of the position fixing member 241. The width in the front-rear direction of the guide hole 126C is, for example, wider than the width in the front-rear direction of the guide holes 126F and 126R and narrower than the length of one side of the washer of the position fixing member 241.

  The battery fixing member 231 has, for example, an L-shaped cross section, and its length is longer than the length between the guide holes 126F and 126R and shorter than the length of the shelf 125 in the front-rear direction. The battery fixing member 231 includes, for example, a shelf contact surface 242 that is a surface for contacting the shelf 125 and a battery contact surface 243 that is a surface for contacting the storage battery B. The width of the shelf contact surface 242 is narrower than the width of the battery contact surface 243, for example.

  In the shelf contact surface 242, for example, a first screw hole, a second screw hole, and a third screw hole for screwing the position fixing member 241 are formed. The distance between the first screw hole and the second screw hole is substantially the same as the distance between the guide holes 126F and 126C, for example. The distance between the second screw hole and the third screw hole is substantially the same as the distance between the guide holes 126C and 126R, for example.

  For example, in the battery fixing member 231, the battery fixing member 231 can be displaced in the left-right direction by loosening the screwing with the position fixing members 241 in the first screw hole, the second screw hole, and the third screw hole. .

  Further, in the battery fixing member 231, the battery fixing member 231 is fixed by tightening the screwing with each position fixing member 241 in the first screw hole, the second screw hole, and the third screw hole.

  For example, the battery fixing member 231 fixes the storage battery B by sandwiching the storage battery B placed on the shelf 125 together with the other battery fixing members 231.

  Specifically, as shown in FIG. 14, the battery fixing members 231J11 and 231J12 are fixed to the shelf 125S1 so as to sandwich the storage batteries B14 placed on the shelf 125S1 together. Thereby, storage battery B14 is fixed to shelf 125S1.

  The battery fixing members 231J13 and 231J14 are fixed to the shelf 125S1 so that the storage batteries B13 placed on the shelf 125S1 are sandwiched together. Thereby, storage battery B13 is fixed to shelf 125S1.

  For example, in a state where the storage battery B11 (not shown) is placed on the shelf 125S1 together with the storage battery B14 between the storage battery B14 and the left rear end of the shelf 125S1, the battery fixing members 231J11 and 231J12 are placed on the shelf 125S1. It fixes to shelf 125S1 so that B14 and B11 may be pinched | interposed jointly. Thereby, storage battery B14, B11 is fixed to shelf 125S1.

  Further, in a state where the storage battery B12 (not shown) is placed on the shelf 125S1 together with the storage battery B13 between the storage battery B13 and the right rear end of the shelf 125S1, the battery fixing members 231J13 and 231J14 are placed on the shelf 125S1. B13 and B12 are fixed to the shelf 125S1 so as to be sandwiched together. Thereby, storage battery B13, B12 is fixed to shelf 125S1.

  For example, the battery fixing member 231 can change the size of the storage battery B to be fixed by being displaced. Specifically, since the battery fixing member 231 can be displaced in the left-right direction, for example, by displacing the battery fixing member 231 according to the size of the storage battery B, the storage battery B is replaced with another battery fixing member 231. It fixes to the shelf 125 so that it may pinch together.

  Since other configurations and operations are the same as those of the storage device according to the first embodiment, detailed description thereof will not be repeated here.

  As described above, in the storage device according to the third embodiment of the present invention, the battery fixing member 231, the position fixing member 241, and the shelf 125 are fixed by sandwiching the storage battery B placed on the shelf 125. By displacing, the size of the storage battery B to be fixed can be changed.

  With such a configuration, for example, even when the type and shape of the storage battery B placed on the shelf 125 is changed due to a specification change, and the size of the storage battery B to be fixed changes, different sizes are used using the same shelf 125. The storage battery B can be fixed. Thereby, since the specification of the shelf 125 can be unified, the cost for responding to the specification change of the storage battery B can be reduced.

  In the storage device 151 according to the third embodiment of the present invention, the battery fixing member 231 is configured to be displaceable in the left-right direction of the shelf 121. However, the present invention is not limited to this. For example, in the shelf 125S1 shown in FIG. 14, the battery fixing member 231 and the guide holes 126F, 126C, and 126R are arranged to be rotated 90 degrees so that the battery fixing member 231 can be displaced in the front-rear direction of the shelf 121. May be.

  In the storage device 151 according to the third embodiment of the present invention, all the battery fixing members 231 are configured to be displaceable. However, the present invention is not limited to this. For example, the structure which cannot displace some battery fixing members 231 may be sufficient. Specifically, for example, in FIG. 14, if at least one of the battery fixing members 231J11, 231J12 is displaceable, the battery fixing member 231J11, 231J12 fixes the storage battery B14 by sandwiching the storage battery B14 together. The size of the storage battery B14 to be fixed can be changed.

  Further, in the storage device 151 according to the third embodiment of the present invention, the battery fixing member 231 is configured to fix the storage battery placed on the shelf 125 to which the battery fixing member 231 is fixed. However, the present invention is not limited to this. The battery fixing member 231 may have a configuration in which, for example, a storage battery placed on the shelf 125 below the shelf 125 to which the battery fixing member 231 is fixed is fixed. Specifically, for example, by fixing the battery fixing member 231 to the lower surface instead of the upper surface of the shelf 125, the storage battery B placed on the shelf 125 one step below can be fixed to the shelf 125.

  Next, another embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  The terminal T23 in the intershelf terminal block 161C2 is electrically connected to the terminal T13 in the intershelf terminal block 161C1 through the battery connection cable 132P12. The terminal T23 in the inter-shelf terminal block 161C4 is electrically connected to the terminal T13 in the inter-shelf terminal block 161C3 through the battery connection cable 132P34. Terminals T23 and T13 in each of the inter-shelf terminal blocks 161C1 and 161C3 are electrically connected.

  The anodes TP11 and TP31 in the storage batteries B11 and B31 are electrically connected to terminals T13 in the inter-shelf terminal blocks 161C1 and 161C3, respectively. Cathodes TM11 and TM31 in storage batteries B11 and B31 are electrically connected to anodes TP12 and TP32 in storage batteries B12 and B32, respectively. Cathodes TM12 and TM32 in storage batteries B12 and B32 are electrically connected to anodes TP13 and TP33 in storage batteries B13 and B33, respectively. Cathodes TM13 and TM33 in storage batteries B13 and B33 are electrically connected to anodes TP14 and TP34 in storage batteries B14 and B34, respectively.

  Cathodes TM14 and TM34 in storage batteries B14 and B34 are electrically connected to terminals T12 in inter-shelf terminal blocks 161C1 and 161C3, respectively. Terminals T12 and T22 in each of the inter-shelf terminal blocks 161C1 and 161C3 are electrically connected.

  The terminal T22 in the inter-shelf terminal block 161C1 is electrically connected to the terminal T22 in the inter-shelf terminal block 161C2 through the battery connection cable 132M12. The terminal T22 in the intershelf terminal block 161C3 is electrically connected to the terminal T22 in the intershelf terminal block 161C4 via the battery connection cable 132M34. Terminals T22 and T12 in each of the inter-shelf terminal blocks 161C2 and 161C4 are electrically connected.

  The terminals T12 and T11 in the inter-shelf terminal block 161C2 are electrically connected by, for example, wiring. The terminals T12 and T11 in the inter-shelf terminal block 161C4 are electrically connected by, for example, wiring. Terminals T11 and T21 in each of the inter-shelf terminal blocks 161C2 and 161C4 are electrically connected.

  The terminal T21 in the intershelf terminal block 161C2 is electrically connected to the terminal T21 in the intershelf terminal block 161C4 via the battery connection cable 132M24.

  The terminal T21 in the inter-shelf terminal block 161C2 is electrically connected to the terminal T32 in the device terminal block 162 via the battery connection cable 132M2b.

  In the power supply device 101 according to the fourth embodiment of the present invention, the battery connection cable 132M2b is configured to be connected to the terminal T21 in the inter-shelf terminal block 161C2 and the terminal T32 in the device terminal block 162. However, the present invention is not limited to this. For example, the battery connection cable 132M2b may be configured to be connected to the terminal T21 in the inter-shelf terminal block 161C4 located closest to the device terminal block 162 instead of the terminal T21 in the inter-shelf terminal block 161C2. Thereby, since the length of the battery connection cable 132M2b can be shortened, the impedance of the battery connection cable 132M2b can be lowered to reduce the power loss, and the manufacturing cost can be lowered.

[Battery connection cable impedance]
As described above, the impedance of the path formed by the intra-shelf cable from the inter-shelf terminal T in the inter-shelf terminal block 161 to the other inter-shelf terminal T in the inter-shelf terminal block 161 via the storage battery B is The shelf 121 is substantially the same.

  Between the shelves 121, for example, a battery connection cable 137 made of the same kind of electric wires and having substantially the same length is attached. For example, as shown in FIG. 17, between the terminal T24 in the inter-shelf terminal block 161C2 and the terminal T24 in the inter-shelf terminal block 161C4, and between the terminal T21 in the inter-shelf terminal block 161C2 and the terminal T21 in the inter-shelf terminal block 161C4 The impedance is substantially the same.

  For example, when the interval between the shelves 121S0 and 121S1 and the interval between the shelves 121S2 and 121S3 are substantially the same, the battery connection cables 132P12, 132M12, 132P34, and 132M34 are configured by, for example, the same type of electric wires and have a length corresponding to the interval. Have That is, the impedance between the first end and the second end of the battery connection cable 132P12, the impedance between the first end and the second end of the battery connection cable 132M12, and between the first end and the second end of the battery connection cable 132P34 The impedance and the impedance between the first end and the second end of the battery connection cable 132M34 are substantially the same.

  Therefore, in the above case, the impedance between the terminal T23 in the inter-shelf terminal block 161C1 and the terminal T23 in the inter-shelf terminal block 161C2, and the impedance between the terminal T23 in the inter-shelf terminal block 161C3 and the terminal T23 in the inter-shelf terminal block 161C4 are It becomes almost the same.

  The impedance between the terminal T22 in the inter-shelf terminal block 161C1 and the terminal T22 in the inter-shelf terminal block 161C2 and the impedance between the terminal T22 in the inter-shelf terminal block 161C3 and the terminal T22 in the inter-shelf terminal block 161C4 are substantially the same. .

  Further, the impedance between terminals T11 and T21, between terminals T12 and T22, between terminals T13 and T23, and between T14 and T24 in the inter-shelf terminal blocks 161C1 to 161C4 is small enough to be ignored. Further, in the inter-shelf terminal blocks 161C2 and 161C4, the impedance between the terminals T11 and T12 electrically connected by the wiring is small enough to be ignored, for example.

  Accordingly, each of the cables formed between the shelf terminal cable and the shelf-to-shelf cable from the device terminal block 162 which is a connection portion between the power supply device 101 and the BMS 501 to the device terminal block 162 via the storage battery B placed on the two shelves 121. The impedance of the path is substantially the same.

  More specifically, the impedance of the path formed by the battery connection cable from the terminal T31 in the device terminal block 162 to the terminal T32 in the device terminal block 162 via the series units BS2 and BS1, and the terminal T31 in the device terminal block 162 Through the series units BS4, BS3 to the terminal T32 in the device terminal block 162, the impedance of the path formed by the battery connection cable is substantially the same.

  Thereby, when charging or discharging the storage battery B in the series units BS <b> 1 to BS <b> 4, substantially the same voltage can be applied to or output from any storage battery B, so that the life of the storage battery B can be extended. .

  Since other configurations and operations are the same as those of the storage device according to the first embodiment, detailed description thereof will not be repeated here.

  As described above, in the storage device according to the fourth embodiment of the present invention, the shelf 121 can mount a plurality of storage batteries B, and the battery connection cables 131, 137, and 145 correspond to the same shelf 121. The battery connection cables 131 and 145 as in-shelf cables for electrically connecting the storage batteries B or between the storage batteries B and other circuits, and the storage batteries B and the storage batteries B placed on the other shelves 121. A shelf-to-shelf cable is included. The in-shelf cable is provided to electrically connect a plurality of storage batteries B placed on the shelf 121 in series. The inter-shelf cable is provided to electrically connect the storage battery B placed on the shelf 121 and the storage battery B placed on the other shelf 121 in series or in parallel.

  With such a configuration, since the electrical connection between the storage batteries B placed on different shelves 121 can be associated with the spatial arrangement of these shelves 121, each storage battery B in the storage device 151 can be associated with each other. It is possible to intuitively determine the set of storage batteries B placed on each shelf 121 as one unit without considering the electrical connection in units of individual storage batteries B.

  Thereby, for example, when designing storage devices 151 having different specifications for electrical connection, mechanism design other than electrical connection can be made common. And the storage apparatus 151 from which the specification of an electrical connection differs can be designed by changing the connection of the cable in a shelf and the cable between shelves. Therefore, design cost and manufacturing cost can be reduced.

  In the storage device according to the fourth embodiment of the present invention, the power supply device 101 is mounted on each shelf 121 from the terminal T31 in the device terminal block 162 that is a connection portion with the BMS 501 that is an external circuit of the power supply device 101. The impedance of each path by the battery connection cable to the terminal T32 in the device terminal block 162 via the storage battery B to be placed is substantially the same.

  With such a configuration, for example, when charging or discharging the storage battery B placed on each shelf 121, substantially the same voltage can be applied to or output from any storage battery B. Therefore, the storage battery B Can extend the lifespan.

  It should be noted that some or all of the components of each device according to the first to fourth embodiments of the present invention can be arbitrarily combined.

  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.
