Further, as will be described later, the electric power of each storage battery 40 can be directly supplied to the load, but the electric power may be interchanged with other storage batteries 40 via the main control panel 44. For example, the surplus power of the battery of the plug-in hybrid vehicle P (see FIG. 1) is supplied to the storage battery 40 connected to the cable, the storage battery 40 is charged, and then the charged power is supplied via the main control version 44. You may make it accommodate in the other storage battery 40. FIG.
FIG. 3 shows an enlarged cross-sectional view of the storage battery 40 accommodated in the partition wall 48 that partitions the washroom 30 and the Japanese-style room 26. As shown in this drawing, the partition wall 48 is configured by fastening a finishing material 62 on both surfaces of a base material 60 composed of a horizontal beam 58 and a vertical beam (not shown). A rectangular opening 64 is formed on the upper edge side of the horizontal rail 58 of one finishing material 62.

A sub-control panel 70 as a (second) control means is disposed on the front surface of the storage battery 40. The sub-control panel 70 includes a capacitor 72, a switching element 74 that converts direct current to alternating current, and a switching unit 76 that switches between a power supply path by discharge from the capacitor 72 and a power supply path from commercial power. The sub control panel 70 is connected to the storage battery 40 (wiring is omitted), and the electric power stored in the storage battery 40 is stored in the capacitor 72. The sub-control panel 70 is also connected to the main control panel 44, and when a discharge signal from the main control panel 44 is input to the sub-control panel 70, the capacitor 72 included in the sub-control panel 70 is discharged by a predetermined amount. It is like that. The sub-control panel 70 also serves as an outlet, and is provided with an insertion port 80 for a plug 78. Since the sub control panel 70 also serves as an outlet, the sub control panel 70 is held in a state of being fitted into the opening 64.
In the above configuration, in the sub-control panel 70 of the storage battery 40 disposed in the inner garage 18, by connecting the power plug of the plug-in hybrid vehicle P to the insertion port 80 of the sub-control panel 70, Excess power may be charged in the storage battery 40 corresponding to the sub control panel 70.
A louver 82 is disposed on the front surface of the sub-control panel 70. The louver 82 plays a role of preventing the storage battery 40 from being overheated by encouraging heat dissipation of the storage battery 40 and circulating indoor air to the storage battery 40 side. As shown in FIGS. 3 and 4, a rectangular opening 84 for inserting a plug 78 is formed at the center of the louver 82, and the opening of the sub control panel 70 is inserted into the opening 84. 80 comes to face. In the present embodiment, the louver 82 is detachably locked to the peripheral edge of the opening 64 by an elastically deformable engagement claw or the like, but may be detachably attached to the sub-control panel 70. Further, a hinge may be provided on the lower edge or side edge of the louver 82, and the louver 82 may be attached to be rotatable around the hinge.
As shown in FIG. 4, an operation panel 86 is disposed below the louver 82. The operation panel 86 is provided with a display unit 88 that displays the storage amount (remaining amount) of the storage battery 40 and operation buttons 90A to 90C. When the operation button 90A is pressed, the switching unit 76 of the sub control panel 70 switches from the power supply path due to the discharge of the capacitor 72 to the power supply path from the commercial power, and when the operation button 90B is pressed, the switching unit 76 supplies the power from the commercial power. The path is switched to a power feeding path by discharging the capacitor 72. Further, when the operation button 90C is pressed, the manual operation is released, and the switching unit 76 is returned to the initial state where the power feeding path is formed by discharging the capacitor 72.
The operation panel 86 disposed in the inner garage 18 is supplied with the surplus power of the battery of the plug-in hybrid vehicle P or the like to the storage battery 40 after the power plug of the plug-in hybrid vehicle P is inserted into the insertion port 80. A switch 90D (illustrated by a two-dot chain line in FIG. 4) may be provided.
FIG. 5 shows a block diagram of a power storage system 92 configured as described above. As shown in this figure, the solar cell panel 20 and the commercial power system 94 are connected to the storage battery 40 via the switching unit 96. The main control panel 44 is connected to the switching unit 76 so as to switch between an external power supply system that stores power generated by the solar battery panel 20 in the storage battery 40 and a commercial power system that receives midnight power in the storage battery 40. It has become.
Further, the main control panel 44 is connected to the sub control panel 70 and the storage amount detection means 97. The storage amount detection means 97 is disposed in each storage battery 40, detects the current storage amount stored in the storage battery 40 (or the remaining amount) and outputs it to the main control panel 44. As the charged amount detection means 97, for example, a charge amount and a discharge amount may be detected using a current sensor and obtained from the integrated value, or another configuration may be used.
Further, the main control panel 44 is connected to a monitor 98. As shown in FIG. 6, the monitor 98 displays the storage amount detected by the storage amount detection means 97 on a screen (display unit) for each location where the storage battery 40 is installed.
As described above, when the surplus power stored in the plug-in hybrid vehicle P is interchanged, the monitor 98 displays how much surplus power is present, as indicated by the two-dot chain line in FIG. A display unit 95 is preferably provided. However, normally, information on the storage amount is obtained from the plug-in hybrid vehicle P based on the information of the power line communication from the plug-in hybrid vehicle P.
The main control panel 44 stores a priority order for charging the storage battery 40 installed indoors in the house 10. As an example, this priority order is determined so that the priority order is higher in order of the required capacity of the storage battery 40. Further, in principle, when the current capacity of the storage battery 40 becomes less than the reference value (predetermined value), the storage battery 40 is preferentially charged. Note that the priority order when charging the storage battery 40 can be arbitrarily changed by operating an operation panel (not shown) provided on the main control panel 44 or by operating the screen of the monitor 98.
The storage battery 40 and the sub-control panel 70 described above can be expanded in the future when the reform or family structure changes.
In the present embodiment, a small lithium ion storage battery (lithium battery) is used as the storage battery 40. However, other storage batteries such as a lead storage battery and a nickel hydride storage battery may be used in addition to the lithium ion storage battery.
First, the overall operation of the power storage system 92 applied in the house 10 according to the present embodiment will be described with reference to FIG.
FIG. 7 shows a system diagram of the power storage system 92 according to the present embodiment. As shown in the figure, the switching unit 96 is switched to the external power receiving path by the main control panel 44 so as to be charged with electric power obtained by solar power generation in the daytime. Thereby, the storage battery 40 is charged by the external power supply system using the solar battery panel 20. Further, the switching unit 96 is switched to the commercial power receiving path by the main control panel 44 in order to use late-night power at night. Thereby, the storage battery 40 is charged by the commercial power system 94 using midnight power.
The storage capacity of the storage battery 40 is set differently depending on the size of the load for each location where the storage battery 40 is installed. That is, some storage batteries 40 have a large storage capacity, some storage batteries 40 have a medium storage capacity, and some storage batteries 40 have a small storage capacity. Incidentally, in the inner garage 18 and the washroom 30, a storage battery 40 having a large storage capacity is installed. In addition, a storage battery 40 having a small storage capacity is installed in the storage space 36 or the Japanese-style room 26. There are two ways of changing the storage capacity of the storage battery 40, one is a method of connecting the required number of storage batteries 40 of the same capacity to increase the storage capacity by an integral multiple, and the other is required. This is a method of preparing and installing in advance a storage battery 40 that can cover a single storage capacity. In the former case, since it is not necessary to prepare in advance a plurality of types of storage batteries 40 having different storage capacities, the connection work can be abolished, and the cost can be reduced accordingly. In the latter case, the necessary storage capacity is covered by the single storage battery 40, so that the installation space can be reduced compared to the case where the storage battery 40 is connected to increase the capacity. Which one to select is determined in consideration of the size and cost of the storage battery housing 66 that can be secured.
The electric power stored in the storage battery 40 is stored in the capacitor 72 of the sub-control panel 70, and the plug 78 (see FIG. 3) of the home appliance 99 (see FIG. 3) or the natural refrigerant heat pump water heater 22 (see FIG. 2) is connected to the outlet. By being inserted into the insertion port 80 of the sub-control panel 70 that also serves as a power source, the switching element 74 converts it into an alternating current of a predetermined frequency and supplies power.
The storage amount (remaining amount) of each storage battery 40 is detected by the storage amount detection means 97 and output to the main control panel 44. The main control panel 44 centrally manages the storage state of each storage battery 40 from the current storage amount (remaining amount) detected by the storage amount detection means 97. Further, the detection result of the charged amount detection means 97 is displayed on the monitor 98 so that it can be easily visually confirmed.
In addition, when managing the storage state of each storage battery 40 with the main control panel 44, the priority order for charging the storage battery 40 is determined in advance as described above, and the storage battery 40 is charged with a higher priority. . In other words, in the case of daytime charging, the main control panel 44 causes the switching unit 96 to select the external power receiving path, but the power obtained by solar power generation is from the solar panel 20 installed in the house 10. It is influenced by the number and performance and is generally limited. In addition, the electric power obtained by solar power generation depends on the weather. Therefore, in order to charge the storage battery 40 efficiently and effectively, it can be said that it is appropriate to charge in order from the one with the highest priority. Therefore, for example, “the storage battery 40 installed in the inner garage 18 → the storage battery 40 installed in the washroom 30 → the storage battery 40 installed in the bathroom 28 → the storage battery 40 installed in the toilet 32 → the storage battery installed in the Japanese room 26” The order of “40 → the storage battery 40 installed at the entrance 24 → the storage battery 40 installed in the storage space 36” is determined in advance, and power is stored in this order. When the power generated by solar power is insufficient, the main control panel 44 switches the switching unit 96 to the commercial power receiving path so that the power is received from the commercial power system 94.
Furthermore, since the amount of electricity stored in each storage battery 40 can be confirmed on the display unit 88 of the operation panel 86 disposed below the louver 82, when using the home appliance 99 that consumes power extremely, It can be switched manually. Specifically, when the operation button 90A is pressed, the switching unit 76 switches to the indoor wiring side that transmits commercial power, and alternating current flows. Thereby, the user's side can avoid the performance fall of the storage battery 40 by sudden electric power use.
Next, control during charging will be described using the flowchart shown in FIG.
First, in step 100, the priority order is confirmed. In the initial state, the priority is set in the above example. However, when a priority change operation is performed by a direct operation or a remote operation on the main control panel 44 or the monitor 98, the priority order is updated.
Next, the routine proceeds to step 102 where it is determined whether or not the external power generation amount is sufficient. This external power generation amount refers to solar power generation by the solar battery panel 20, and when sufficient solar radiation is obtained on a clear day, it is determined that a power generation amount equal to or greater than a predetermined value set in advance is obtained. Affirmed. If the determination in step 102 is affirmative, the process proceeds to step 104, and charging of the storage battery 40 is started through the external power receiving path. That is, the switching unit 96 is selected as the external power receiving path.
On the other hand, if a sufficient amount of power generation cannot be obtained due to rain or the like, the result in Step 102 is negative and the process proceeds to Step 106, where the switching unit 96 is switched to change the power receiving path from the external power receiving path to the commercial power receiving path. Is done. Thereafter, the process proceeds to step 108, and power storage in the storage battery 40 is started through the commercial power receiving path.
Next, the routine proceeds to step 110, where the storage amount of each storage battery 40 is calculated. Next, the routine proceeds to step 112, where it is determined whether or not there is a storage amount that is a calculation result less than a reference value. If the determination in step 112 is affirmative, the process proceeds to step 114, and interrupt charging is performed. That is, the storage battery 40 having a value less than the reference value is forcibly rapidly charged regardless of the priority order. As a result, the storage battery 40 is prevented from being out of charge. If interrupt charging is performed in step 114, the process returns to step 100.
On the other hand, if the result in Step 112 is negative, it means that all the storage batteries 40 have an amount of stored electricity that is equal to or greater than their respective reference values, so that the process returns to Step 100.
The above-described control at the time of charging is an example, and changes are appropriately made as necessary. For example, the reference value of the storage amount of the storage battery 40 may be uniformly defined as 30% of full charge for all the storage batteries 40, or may be weighted according to the priority order. For example, for a storage battery 40 in a location where a large amount of power storage is required, such as the inner garage 18 and the washroom 30, the power storage amount multiplied by 1.5 as a safety factor (that is, 45%) The storage battery 40, which may have a small capacity, may be regulated in such a manner that the storage capacity is multiplied by 1.0 as a safety factor (ie, remains 30%).
The above is the contents of the overall operation of the power storage system 92 according to the present embodiment and the control at the time of charging. The operations and effects corresponding to the invention according to each claim will be described below.
In this embodiment, since the storage battery accommodating part 66 and the storage battery 40 are distributed and arranged in a plurality of locations in the house 10, when the power is required, the storage battery 40 closest to the required location. Power can be supplied from. Therefore, it is easier to take out the electric power stored in the storage battery 40 as compared with the case where the storage battery housing part and the storage battery are installed only in one place of the house. As a result, according to the present embodiment, it is possible to easily take out the electric power corresponding to the load from various places in the room.
Moreover, in this embodiment, each storage battery 40 can be selectively stored from either an external power supply system using solar power generation or a commercial power system using midnight power. It is possible to store electricity in the storage battery 40 or store in the storage battery 40 power generated by daytime solar power generation. For this reason, according to this embodiment, the storage battery 40 can be charged at low cost.
Furthermore, in the present embodiment, the storage amount (remaining amount) of the storage batteries 40 distributed in various places is displayed on the monitor 98 at a time, so that the storage amount of each storage battery 40 can be instantly confirmed by looking at the monitor 98 display. can do. Therefore, according to the present embodiment, the storage amount of each storage battery 40 can be easily monitored.
Moreover, in this embodiment, since the priority at the time of charging the storage battery 40 is determined in advance and the main control panel 44 is charged in order from the highest priority, the amount of photovoltaic power generation is small. In such a case, the battery 40 is charged from a higher priority. Therefore, it is possible to prevent a situation in which the remaining amount is insufficient while the storage batteries 40 such as the inner garage 18, the washroom 30, and the bathroom 28 are relatively unknown. As a result, according to the present embodiment, the power supplied from the storage battery 40 can be controlled according to the importance.
Furthermore, in this embodiment, when the storage amount of any of the storage batteries 40 becomes less than the reference value by the main control panel 44, the storage battery 40 is charged with the highest priority regardless of the priority order. Even if the rank is lower, the stored amount (remaining amount) does not become zero. As a result, according to the present embodiment, it is possible to stably maintain the storage state of the storage battery network including the storage batteries 40 arranged in a distributed manner.
Moreover, in this embodiment, although the load to be used is different for each location where the storage battery 40 is installed and the required power is different, the storage amount of the storage battery 40 is set according to each required power. It does not happen that the storage amount of the storage battery 40 is insufficient with respect to the load used at the storage battery installation location. For this reason, according to this embodiment, the electric power requested | required for every storage battery installation location can be supplied.
Furthermore, in this embodiment, the storage battery 40 is comprised by the 1 or several storage battery, and when the above is implement | achieved with 1 storage battery, there exists a capacity | capacitance more than the electric power requested | required for each storage battery installation location. A storage battery is used. On the other hand, when the above is realized with a plurality of storage batteries, the storage batteries having the same capacity are connected or used so that the capacity is equal to or greater than the power required for each storage battery installation location. Used in combination. Whether to configure with one storage battery or to connect a plurality of storage batteries may be selected in accordance with factors such as the specifications of the storage battery and the size of the storage battery housing. For this reason, according to the present embodiment, the system can be constructed taking into account the specifications of the storage battery, the size of the storage battery housing portion, and the like, and can be applied to various planning houses.
Moreover, in this embodiment, since some storage batteries 40 are arrange | positioned in the inner garage 18, it can charge directly from the inner garage 18 with respect to the vehicle which needs charging, such as the plug-in hybrid vehicle P. it can. For this reason, according to the present embodiment, the storage batteries 40 including the inner garage 18 can be distributed and power supply according to the load can be performed easily and quickly from the inner garage 18. Furthermore, since the storage battery 40 is disposed in the inner garage 18 and charging from the storage battery 40 to the plug-in hybrid vehicle P is enabled, surplus power can be accommodated from the plug-in hybrid vehicle P as described above to another storage battery 40. It is also possible to do.
Furthermore, in this embodiment, the storage battery housing 66 is provided with a sub-control panel 70 that functions as an outlet, and a home appliance 99 or a natural refrigerant heat pump water heater is directly connected to the insertion port 80 of the sub-control panel 70. Since it is possible, the wiring of the sub control panel 70 becomes unnecessary as compared with the case where the sub control panel 70 is provided at a location different from the storage battery housing portion 66. For this reason, it is not necessary to secure a wiring routing route, and the degree of freedom in planning increases accordingly. In addition, since wiring work is not necessary, work in the building can be reduced. As a result, according to the present embodiment, the degree of freedom in planning can be increased, and the work period can be shortened by reducing the work in the building site.
In the embodiment described above, the storage batteries 40 are distributed and arranged at a plurality of locations inside the house 10, but this is not a limitation, and the storage batteries may be distributed at a plurality of locations inside and outside the house. For example, in this embodiment, the inner garage 18 is provided on the first floor portion 12 of the house 10, but when the garage is installed outdoors in the house, one or more storage batteries are arranged in the garage. May be.
Moreover, in embodiment mentioned above, although this invention was applied with respect to the house 10, you may apply this invention not only to this but buildings, such as unit buildings other than a house.
Furthermore, in the embodiment described above, the solar cell panel 20 has been mainly described as an example of the external power supply system. However, as described above, the external power supply system includes plug-in hybrid vehicles P, electric vehicles, fuel cell vehicles, and the like. The surplus power of other vehicles is also included. The surplus power of the vehicle is stored in the garage when the vehicle enters the garage, so that the storage battery (including the replacement battery installed in the building for replacing the battery of the electric vehicle itself) is also supplied to the vehicle. Since it can be accommodated, it can be used as an external power source.
