  Below, the structure of the electric power supply system 1 which concerns on 1st embodiment of this invention is demonstrated using FIG.

  The power supply system 1 according to the present embodiment is provided in, for example, a house 2. The power supply system 1 is for supplying power from a power supply source such as the commercial power source S and the power storage device 10 to the load of the house 2. In the present embodiment, the power supply system 1 uses power from a power supply source (such as the power storage device 10) other than the commercial power source S during the power failure when the power from the commercial power source S is interrupted. The load can be supplied to a highly important load (an important load 50 described later).

  In the power supply system 1, the load on the house 2 is divided into a general load 40 and an important load 50 in advance. The important load 50 is a load having a higher importance than the general load 40. More specifically, the important load 50 is a power outlet to which a device that needs to be supplied with power compared to the general load 40 in the event of a power failure, the device itself, or the like. 3 (hereinafter simply referred to as “living 3” for convenience), ceiling lighting 55 of the living room 3 and the like. Thus, in this embodiment, the important load 50 is concentrated on the living room 3 of the house 2.

  In addition, the electric power from the photovoltaic power generation unit 20 is output to the electric box 81 side (indoor side) described later via the power storage device 10. Therefore, for the sake of convenience, the power from the power storage device 10 includes the power from the solar power generation unit 20 unless otherwise specified.

  The distribution board 30 distributes electric power as appropriate. The distribution board 30 includes a leakage breaker, a wiring breaker, a control unit, and the like (not shown). Distribution board 30 is connected to commercial power source S via first electric circuit L1. In addition, distribution board 30 is connected to power storage device 10 (more specifically, normal-time output unit 11 of power storage device 10) via second electrical path L2. An electric box 81 that connects the outdoor side and the indoor side of the second electric circuit L2 is provided in the middle of the second electric circuit L2.

  The general load 40 is a power outlet, the device itself, or the like to which a device that is less required to supply power than the important load 50 is connected during the power failure. Specifically, the general load 40 includes, for example, a power outlet in the hallway of the house 2 and a ceiling lighting in the bedroom (not shown). The general load 40 is connected to the distribution board 30 via the third electric circuit L3.

  The important load 50 is a power outlet, the device itself, or the like to which a device that needs to be supplied with electric power is compared with the general load 40 during a power failure among the loads of the house 2.

In addition, between the distribution board 30 and the important load 50 in the 4th electric circuit L4, the switch part 70 mentioned later is provided. Hereinafter, in the fourth electric circuit L4, the upstream side (distribution panel 30 side) of the switching unit 70 is referred to as “upstream fourth electric circuit L4a”, and the downstream side of the switching unit 70 (important load 50 side). This is referred to as “downstream fourth electric path L4b”. A wiring unit 82 is provided in the middle of the downstream fourth electric path L4b, and the downstream side of the downstream fourth electric path L4b is appropriately branched.

  In the present embodiment, as shown in FIG. 1, as the important load 50, the information box outlet 51, the refrigerator outlet 52, the TV outlet 53, the outdoor outlet 54, the ceiling lighting 55, and the notifying outlet 56 are provided. Is provided.

  The information box outlet 51 is a power outlet provided in an information box 51a (information distribution board) having a plurality of hubs and the like.

The outdoor outlet 54 is a power outlet to which the gas water heater 54a is connected. The outdoor outlet 54 is provided on the outer wall of the house 2, that is, outdoors.

  Moreover, the outlet 56 with a notification unit is a power outlet that does not have a particular purpose (connected device). The outlet 56 with a notification unit is provided in the living room 3. Note that a detailed description of the configuration of the notification unit outlet 56 will be given later.

  The notification unit 60 notifies that the outlet 56 with a notification unit is in a usable (powered) state during a power failure. The alerting | reporting part 60 is connected with the switching part 70 mentioned later via the 5th electric circuit L5. The notification unit 60 is configured by an ultra-thin LED illumination having a square frame shape when viewed from the front (see FIG. 5), and can emit light when electric power is supplied. The notification unit 60 is provided integrally with the outlet 56 with a notification unit in the living room 3. As will be described later, the notification unit 60 is configured to emit light when power is supplied at the time of a power failure, and performs notification by the light emission. Note that the notification unit 60 is configured not to emit light because electric power is not supplied during normal operation.

  The switching unit 70 is a switch that switches a power supply source of power supplied to the important load 50 during a power failure and during a normal time (the power from the commercial power source S is not cut off). Switching unit 70 is provided among distribution board 30, important load 50, and power storage device 10. Specifically, the switching unit 70 is connected to the distribution board 30 via the upstream fourth electric path L4a. The switching unit 70 is connected to the important load 50 via the downstream fourth electric path L4b. In addition, switching unit 70 is connected to power storage device 10 (more specifically, output unit 12 at the time of power failure of power storage device 10) via sixth electric circuit L6. In the middle of the sixth electric circuit L6, an electric box 81 that connects the outdoor side and the indoor side of the sixth electric circuit L6 is provided.

  Hereinafter, the configuration of the switching unit 70 will be described in detail with reference to FIGS. 1 and 2.

  In the switching unit 70, the end (contact) of the downstream fourth electric circuit L4b is the end (contact) of the upstream fourth electric circuit L4a or the end (contact) of the sixth electric circuit L6 depending on whether or not a power failure occurs. It is connected to either one of these.

  Specifically, as shown in FIGS. 1 and 2 (a), at the normal time, the end of the downstream fourth electrical path L4b is connected to the end of the upstream fourth electrical path L4a. Thus, the important load 50 is connected to the commercial power source S through the upstream fourth electric circuit L4a and the first electric circuit L1, and the power storage device 10 (more details) through the upstream fourth electric circuit L4a and the second electric circuit L2. Are connected to the normal output unit 11) of the power storage device 10.

  Moreover, as shown in FIG.2 (b), at the time of a power failure, the edge part of the downstream 4th electric circuit L4b is connected with the edge part of the 6th electric circuit L6. In this way, the important load 50 is connected to the power storage device 10 (more specifically, the power failure time output unit 12 of the power storage device 10) via the upstream fourth electric circuit L4a and the sixth electric circuit L6.

  In the switching unit 70, the fifth electric circuit L5 is connected to the upstream side (distribution panel 30 side) of the end (contact point) of the sixth electric circuit L6.

  In the present embodiment, switching in the switching unit 70 is manually performed at the time of a power failure.

  Hereinafter, a power supply mode in a normal time will be described with reference to FIG.

  In normal times, as described above, the important load 50 is connected to the commercial power source S via the upstream fourth electric circuit L4a and the first electric circuit L1, and via the upstream fourth electric circuit L4a and the second electric circuit L2. Connected to the power storage device 10 (more specifically, the normal-time output unit 11 of the power storage device 10). Therefore, as shown in FIG. 3, power from the commercial power source S or the normal output unit 11 of the power storage device 10 as a power supply source is supplied to the important load 50 via the distribution board 30. Further, the power from the commercial power source S or the normal output unit 11 of the power storage device 10 is supplied to the general load 40 via the distribution board 30 as a power supply source.

  Below, the supply aspect of the electric power at the time of a power failure is demonstrated using FIG.

  In the event of a power failure, as described above, the important load 50 is connected to the power storage device 10 (more specifically, the power failure time output unit 12 of the power storage device 10) via the downstream fourth electric circuit L4b and the sixth electric circuit L6. The Therefore, as shown in FIG. 4, at the time of a power failure, the power storage device 10 is disconnected from the commercial power source S, and power from the power failure device output unit 12 of the power storage device 10 serves as a power supply source via the distribution board 30. First, it is supplied to the important load 50. In addition, since no power is supplied to the distribution board 30, no power is supplied to the general load 40.

  In addition, when the power from the output unit 12 at the time of the power failure of the power storage device 10 can be supplied to the important load 50 without the distribution board 30 as a power supply source at the time of the power failure, the output from the output unit 12 at the time of the power failure Electric power is supplied to the alerting | reporting part 60 via the 5th electric circuit L5.

  As described above, in the power supply system 1, the power from the power storage device 10 can be supplied only to the important load 50 having a high degree of importance among the loads of the house 2 during a power failure. As a result, the power from the power storage device 10 (more specifically, the photovoltaic power generation unit 20) is effectively used, and equipment that needs to be supplied with power compared to the general load 40 is as long as possible in the event of a power failure. Can be used throughout.

  Moreover, according to switching of the switch part 70, electric power can be supplied to the alerting | reporting part 60 only at the time of a power failure. Thus, when the power from the output unit 12 at the time of a power failure of the power storage device 10 is supplied via the sixth electric circuit L6 and the fifth electric circuit L5, the notification unit 60 can emit light by the supplied electric power. Thus, the alerting | reporting part 60 can alert | report that the outlet socket 56 with an alerting | reporting part is a usable state at the time of a power failure by light-emitting only at the time of a power failure.

  Hereinafter, the configuration of the notification unit provided outlet 56 will be described in detail with reference to FIGS. 5 and 6.

  As described above, the notification unit 60 is integrally provided in the outlet 56 with the notification unit. Therefore, in the following description, it is assumed that the notifying unit-equipped outlet 56 includes the notifying unit 60 (assuming that the notifying unit 60 is a part of the notifying unit-provided outlet 56). 5 and 6, the vertical direction and the front-rear direction are defined according to the arrows shown in the drawings. Further, the forward direction refers to the indoor side with reference to the inner wall of the living room 3.

  As shown in FIG. 5, the outlet 56 with a notification unit mainly includes an outlet unit 110, a notification unit 60, a mounting frame 120, and a cover plate 130.

  The outlet unit 110 has two insertion ports. The two insertion openings are arranged vertically spaced from each other. The outlet 110 is provided with a mounting bracket 111. The outlet side 110 is connected to the downstream fourth electric path L4b.

  As described above, the notification unit 60 is a square frame-shaped ultra-thin LED illumination having a center opened in a front view. The notification unit 60 is disposed in front of the outlet unit 110 (inside the room). The notification unit 60 is connected to the fifth electric circuit L5.

  The attachment frame 120 is for attaching the outlet 110 to the attachment bracket 111. The attachment frame 120 is disposed in front of the notification unit 60. The mounting frame 120 is formed in a square frame shape having an opening at the center in front view.

  The cover plate 130 is for covering the mounting frame 120. The cover plate 130 is disposed in front of the mounting frame 120. The cover plate 130 is formed in a square frame shape having an opening at the center when viewed from the front. Further, the outline of the cover plate 130 is formed larger than the notification unit 60 in a front view.

  In this way, when the outlet part 110, the notification part 60, the mounting frame 120 and the cover plate 130 are fixed to each other, as shown in FIG. It is formed. In the outlet 56 with the notification unit, the notification unit 60 is integrally provided, but the notification unit 60 is not visually recognized in front view. That is, since the notification unit 60 is concealed inside the outlet 56 with a notification unit, the outlet 56 with a notification unit has the same appearance as a general power outlet. Since the outlet section 110 is connected to the downstream side fourth electric circuit L4b, the notifying outlet 56 with the notification section can be used regardless of whether or not a power failure occurs (regardless of whether it is normal or during a power failure).

  Moreover, since the alerting | reporting part 60 is connected with the 5th electric circuit L5, the electric power from the output part 12 at the time of a power failure of the electrical storage apparatus 10 is supplied at the time of a power failure. Thus, at the time of a power failure, as shown in FIG. 6 (b), the notification unit 60 emits light to notify that the outlet 56 with the notification unit is in a usable state. Here, the outlet 56 with a notification unit has the same appearance as a general power outlet as described above. In this way, the outlet 56 with a notification unit is indistinguishable from the appearance of a general power outlet, and the design is impaired (that is, another power outlet in the living room 3 (a power source without the notification unit 60 provided). It is possible to suppress the conspicuousness due to the different appearance from the outlet).

As described above, in the power supply system 1 according to the present embodiment,
A distribution board 30 for distributing power from the commercial power source S;
An important load 50 (first load) including an outlet 56 with a notification unit connected to the distribution board 30;
A power output device (power storage device 10 and solar power generation unit 20) having a power outage output unit 12 capable of outputting power during a power outage other than normal time;
Provided between the distribution board 30, the important load 50 (first load), and the power failure output unit 12, and connect the distribution board 30 and the important load 50 (first load) during normal operation. And a switching unit 70 that switches to connect the output unit 12 and the important load 50 (first load) at the time of a power failure,
A notification unit 60 connected between the switching unit 70 and the power failure output unit 12 and performing a predetermined notification operation when power is supplied;
It comprises.

  With such a configuration, when the power from the commercial power source S is supplied to the important load 50 in the normal time, the power is not supplied to the notification unit 60, and the power from the output unit 12 at the time of the power outage of the power output device is at the time of a power outage. When the important load 50 is supplied, power can be supplied to the notification unit 60. That is, in the power supply system 1, whether the state in which the outlet 56 with a notification unit that can be used regardless of whether it is normal or during a power failure is usable (powered) is due to the power from the commercial power source S at the normal time, or a power failure. It can be determined whether the power is from a power source other than the commercial power source S at the time.

  Moreover, it can be easily recognized by the notification performed by the notification unit 60 that the outlet 56 with the notification unit can be used (powered) during a power failure.

In the power supply system 1,
The power output device has a normal-time output unit 11 that can output power at normal time,
The normal time output unit 11 is connected to the distribution board 30.

  With such a configuration, not only the power from the commercial power source S but also the power outlet from the power output device (the power storage device 10 and the solar power generation unit 20) that can be used at the time of a power failure is used. 56 can be set in a power-feedable state.

In the power supply system 1,
The power output device includes a power storage device 10 (storage battery) and a solar power generation unit 20 (a power generation unit capable of generating power using natural energy).

  With such a configuration, the notification unit 60 can perform notification using the power from the power storage device 10 and the solar power generation unit 20 (which supplies power to the notification-unit-equipped outlet 56) during a power failure.

In the power supply system 1,
The notification unit 60 is provided integrally with the outlet 56 with the notification unit.

  With such a configuration, the notification unit 60 is provided integrally with the outlet 56 with the notification unit, so that the distance between the power outlet to be notified and the notification unit 60 can be eliminated (closed). The space can be made compact.

  In addition, since the distance between the power outlet to be notified and the notification unit 60 can be eliminated (closed), the notification target by the notification unit 60 can be clarified. In particular, in the present embodiment, notification by the notification unit 60 is performed by light emission of the notification unit 60. That is, the notification unit 60 does not display a specific message such as “a power outage but this outlet is usable”, but only emits light, but the notification unit outlet 56 can be used. It can be easily recognized that it is in a state.

  Moreover, if the outlet 56 with a notification unit is constructed, the power outlet and the notification unit 60 to be notified are constructed at the same time (since it is not necessary to construct them separately), so that workability is improved. Can do.

In the power supply system 1,
The notification unit 60 is formed so as to be capable of emitting light by power feeding, and is concealed inside the outlet 56 with the notification unit.

  With such a configuration, the notification unit outlet 56 is indistinguishable from a general power outlet, so that the design is impaired (that is, for example, a power outlet in which no other notification unit 60 is provided). It can be suppressed that it becomes noticeable due to the difference in appearance.

In the power supply system 1,
A general load 40 (second load) different from the important load 50 (first load) is connected to the distribution board.

  With such a configuration, when there are a plurality of different types of loads, the notification unit 60 can notify one type of load.

  Moreover, in the power supply system 1, since the notification by the notification unit 60 is performed by light emission, the notification unit 60 can also be used as emergency lighting during a power failure.

In addition, the outlet 56 with a notification unit is an embodiment of a power outlet.
The important load 50 is an embodiment of the first load.
The general load 40 is an embodiment of the second load.

  Although the first embodiment has been described above, the present invention is not limited to the above-described configuration, and various modifications can be made within the scope of the invention described in the claims.

  For example, although the power supply system 1 according to the present embodiment is provided in the house 2, it is not limited to this, and may be provided in an office building, a hospital, or the like.

  Further, the distribution of the important load 50 and the general load 40 is not limited to that according to the present embodiment.

  In the present embodiment, the power storage device 10 and the solar power generation unit 20 are provided as emergency power supply sources. However, the present invention is not limited to this, and either the power storage device 10 or the solar power generation unit 20 is provided. Only one may be provided. In addition, the solar power generation unit 20 is connected to the second electric circuit L2 and the sixth electric circuit L6 through the power storage device 10, but is connected to the second electric circuit L2 and the like through the hybrid power conditioner or the like (without the power storage device 10). It may be connected to the electric circuit L2 and the sixth electric circuit L6.

  Moreover, in this embodiment, although the alerting | reporting by the alerting | reporting part 60 was performed by light emission, it is not limited to this. For example, the notification unit 60 may include a display unit to display a specific message such as “There is a power outage but this outlet is usable”.

  Moreover, in this embodiment, although the alerting | reporting part 60 was provided integrally with the outlet socket 56 with an alerting | reporting part, it is not limited to this. The notification unit 60 may be provided separately from the outlet 56 with a notification unit.

  Moreover, the alerting | reporting part 60 can also be used as what alert | reports the usable state of another member instead of a power outlet. For example, if the notification unit 60 is provided on the illumination switch plate of the ceiling illumination 55, it can be notified that the ceiling illumination 55 can be used by operating the illumination switch plate during a power failure.

  Further, in the present embodiment, in the outlet 56 with a notification unit, the notification unit 60 is interposed between the outlet unit 110 and the mounting frame 120, but the present invention is not limited to this, and any arbitrary Can be placed in place. Moreover, although the alerting | reporting part 60 was concealed inside the outlet socket 56 with an alerting | reporting part, it may be exposed outside from the cover plate 130 of the outlet socket 56 with an alerting | reporting part by front view, for example.

  Moreover, in this embodiment, although it was set as the structure which uses sunlight as natural energy in the solar power generation part 20, the natural energy to be used may be hydraulic power, a wind force, tidal power etc., for example.

  Further, the configuration of the switching unit 70 is not limited to that according to the present embodiment. For example, in the present embodiment, the switching in the switching unit 70 is manually performed at the time of a power failure, but may be automatically performed by detecting the power failure. A specific description will be given below.

  FIGS. 7A and 7B are diagrams illustrating the configuration of the switching unit 270 according to another embodiment.

  The switching unit 270 includes a normal relay 271 and a power failure relay 272. The normal relay 271 switches the connection state between the end of the downstream fourth electrical path L4b and the end of the upstream fourth electrical path L4a. The power failure relay 272 switches the connection state between the end of the downstream fourth electric circuit L4b and the end of the sixth electric circuit L6.

  The normal relay 271 and the power failure relay 272 are operated exclusively with each other. That is, when the normal relay 271 is turned on (connected state), the power failure relay 272 is turned off (released from the connected state). Further, when the normal relay 271 is turned off (release of the connected state), the power failure relay 272 is turned on (connected state).

  Specifically, in the normal state, as shown in FIG. 7A, the normal relay 271 is turned on (connected state) and the power failure relay 272 is turned off (released from the connected state). In the event of a power failure, as shown in FIG. 7B, when the normal relay 271 is turned off (release of the connection state), the power failure relay 272 is turned on (connection state).

  The operations of the normal relay 271 and the power failure relay 272 are controlled by a control device (not shown).

  In the switching unit 270 configured as described above, similarly to the switching unit 70 as described above, the power supply source of the power supplied to the important load 50 can be switched between a power failure and a normal time. Switching in the unit 70 can be automatically performed at the time of a power failure. The switching in the switching unit 70 may be performed by the switching unit 270 by itself according to the power from the commercial power source S.

  Below, the structure of the electric power supply system 301 which concerns on 2nd embodiment of this invention is demonstrated using FIG.8 and FIG.9.

  In addition, below, about the apparatus comprised similarly to the electric power supply system 1 which concerns on 1st embodiment, the code | symbol same as 1st embodiment is attached | subjected and the description is abbreviate | omitted.

  The power supply system 301 according to the second embodiment is different from the power supply system 1 according to the first embodiment in the configuration of the outlet 356 with a notification unit. Therefore, the outlet 356 with a notification unit according to the second embodiment will be described below.

  The outlet 356 with a notification unit according to the second embodiment relates to the first embodiment in that a notification unit 360, a power supply module 370, a communication unit 380, and a light emission control unit 390 are integrally provided instead of the notification unit 60. It is different from the outlet 356 with a notification unit.

  The notification unit 360 is configured by an LED light emitting element. The notification unit 360 is appropriately mounted over the entire printed circuit board formed in a square frame shape when viewed from the front. The notification unit 360 can operate in a plurality of light emission modes having different colors and light emission patterns by being controlled by a light emission control unit 390 described later. Specifically, the notification unit 360 can light up in blue, yellow, and red, or blink in red.

  The power supply module 370 converts power from the output unit 12 at the time of a power failure as appropriate. The power supply module 370 can operate the notification unit 360 by supplying the converted power to the notification unit 360.

  Communication unit 380 communicates with power storage device 10. Communication unit 380 is configured to be able to communicate with power storage device 10 using a wireless LAN or the like. The communication unit 380 communicates with the power storage device 10 to generate power (generated power value) of the solar power generation unit 20, the remaining amount of the power storage device 10, the state of the power storage device 10 (charge / discharge state), the power storage device 10 discharge power (discharge power value) and charge power (charge power value) of the power storage device 10 can be acquired. In addition, in 2nd embodiment, the electrical storage apparatus 10 is comprised so that acquisition of the generated electric power (value of generated electric power) from the solar power generation part 20 is possible. In addition, the communication unit 380 can transmit the generated power acquired from the power storage device 10 to the light emission control unit 390 by transmitting a signal to the light emission control unit 390.

  The light emission control unit 390 controls the light emission mode of the notification unit 360. The light emission control unit 390 includes an arithmetic processing unit, a storage unit, and the like. The light emission control unit 390 stores a program and various information in the storage unit, and controls the light emission mode of the notification unit 360 by reading and processing the program and various information by the arithmetic processing unit. it can.

  Hereinafter, the process of controlling the light emission mode of the notification unit 360 by the light emission control unit 390 will be described in detail with reference to FIG.

  The process of controlling the light emission mode shown in FIG. 10 is performed by causing the notification unit 360 to emit light in a mode corresponding to the remaining power available from the power storage device 10 and the solar power generation unit 20 in the event of a power failure. This is for informing whether or not to refrain from use. In the present embodiment, the surplus power is power necessary to maintain power supply to the important load 50. When the important load 50 and the power failure output unit 12 are connected during a power failure (see FIG. 4), the light emission control unit 390 starts a process of controlling the light emission mode. When the processing is started, the light emission control unit 390 transmits the generated power of the solar power generation unit 20 from the power storage device 10 through the communication unit 380, the remaining amount of the power storage device 10, the state of the power storage device 10, the power storage device 10 The discharge power and the charge power of the power storage device 10 are acquired.

  In step S110, the light emission control unit 390 determines whether the generated power of the solar power generation unit 20 is greater than 0W. The light emission control part 390 transfers to step S120, when the generated electric power of the solar power generation part 20 is larger than 0W (step S110: Yes). On the other hand, the light emission control part 390 transfers to step S160, when the electric power generation of the solar power generation part 20 is 0 W or less (step S110: No).

In step S120, the light emission control unit 390 determines whether the supply available time H is longer than 1.0 hour. The supply possible time H is a time indicating how much power consumption of the important load 50 can be covered by the power storage device 10 alone. When calculating the supplyable time H, the light emission control unit 390 first calculates the current supply power K (power consumption of the important load 50) using the following equation (1).
K = G + C−D (1)
In the formula (1), G is the generated power of the solar power generation unit 20, C is the discharge power of the power storage device 10, and D is the charging power of the power storage device 10 (the power storage device 10 is charged from the solar power generation unit 20). Power).

In step S120, the light emission control unit 390 that has calculated the current supply power K calculates the supply available time H using the following equation (2).
H = Q ÷ K (2)
In the formula (2), Q represents the remaining amount of the power storage device 10.

  In step S120, the light emission control unit 390 that has calculated the supplyable time H shifts to step S130 when the supplyable time H is greater than 1.0 hour (step S120: Yes). On the other hand, the light emission control part 390 transfers to step S150, when the supply possible time H is 1.0 hour or less (step S120: No).

  In step S <b> 130, the light emission control unit 390 confirms the state of the power storage device 10. When the power storage device 10 is in a charged state or a standby state (step S130: charge or standby), the light emission control unit 390 proceeds to step S140. On the other hand, when the power storage device 10 is in a discharged state (step S130: discharge), the light emission control unit 390 proceeds to step S150.

  In step S140, the light emission control unit 390 lights the notification unit 360 in blue. In the light emission control unit 390, the photovoltaic power generation unit 20 is in a power generation state (step S110: Yes), and the remaining amount of the power storage device 10 is greater than or equal to the power consumption of the important load 50 (step S120: Yes). When the remaining amount of the device 10 is not reduced (step S130: charge or standby), the process proceeds to step S140. In this case, since the electric power of the power storage device 10 and the photovoltaic power generation unit 20 is surplus, stable power supply to the important load 50 can be expected even when the outlet 356 with the notification unit is used.

  For this reason, the light emission control part 390 judges that there is sufficient power when it transfers to step S140, and makes the alerting | reporting part 360 light blue. Thereby, the light emission control part 390 alert | reports that it is not necessary to refrain from using the socket 356 with an alerting | reporting part. When the process of step S140 ends, the light emission control unit 390 ends the light emission mode control process.

  In step S120, the light emission control unit 390 lights the notification unit 360 in yellow when the supplyable time H is 1.0 hour or less in step S120 and in step S150 which is shifted when it is determined that the battery is in the discharge state in step S130.

  The light emission control unit 390 generates power when the solar power generation unit 20 generates power (step S110: Yes), but the remaining amount of the power storage device 10 is small with respect to the power consumption of the important load 50 (step S120: No). The process proceeds from step S120 to step S150. In this case, when the photovoltaic power generation unit 20 cannot generate power and covers the power of the important load 50 with the power storage device 10 alone (for example, at night), the power supply to the important load 50 is interrupted in a short time. There is a possibility that. For this reason, when it transfers to step S150 from step S120, it is desirable to charge the electrical storage apparatus 10 with the electric power of the photovoltaic power generation part 20. FIG. Therefore, in this case, it is desirable to refrain from using the outlet 356 with a notification unit if possible.

  Further, the light emission control unit 390 generates power while the solar power generation unit 20 generates power and the remaining amount of the power storage device 10 is greater than or equal to the power consumption of the important load 50 (step S110: Yes, step S120: Yes). When the device 10 is discharged (step S130: discharge state), the process proceeds from step S130 to step S150. In this case, since the power storage device 10 is discharged without being able to cover the power consumption of the important load 50 only by the power from the solar power generation unit 20, if the outlet 356 with the notification unit is used, the discharge power of the power storage device 10 is reduced. This increases, and the remaining amount of the power storage device 10 tends to decrease. Therefore, also in this case, it is desirable to refrain from using the outlet 356 with a notification unit if possible.

  Thus, the light emission control part 390 transfers to step S150, when there is not a sufficient margin in electric power. When the process proceeds to step S150, the light emission control unit 390 determines that there is not enough remaining power, and turns on the notification unit 360 in yellow (controls the light emission mode different from that in step S140). Accordingly, the light emission control unit 390 notifies that it is better to refrain from using the outlet 356 with a notification unit if possible. When the process of step S150 ends, the light emission control unit 390 ends the light emission mode control process.

  In step S160, which is shifted when the generated power of the photovoltaic power generation unit 20 is 0 W or less in step S110, the light emission control unit 390 determines whether or not the supplyable time H is longer than 2.0 hours in the same manner as in step S120. Judging. In step S160, since the photovoltaic power generation unit 20 is not generating power, the remaining amount of the power storage device 10 is exhausted in a shorter time than when the process proceeds to step S120 (power supply to the important load 50 is interrupted). Is assumed. Therefore, in step S160, the time (2.0 hours) compared with the supply available time H is made longer than that in step S120 (1.0 hours). The light emission control part 390 transfers to step S170, when the supply possible time H is larger than 2.0 hours (step S160: Yes). On the other hand, the light emission control part 390 transfers to step S190, when the supply possible time H is 2.0 hours or less (step S160: No).

  In step S170, the light emission control unit 390 checks whether or not the current time is a time zone between 17:00 and 6 o'clock. If the current time is not a time zone between 17:00 and 6 o'clock, that is, if it is a time zone during which sunlight is radiated in the morning, daytime or the like (step S170: No), The process proceeds to S150. On the other hand, if the current time is a time zone between 17:00 and 6 o'clock, that is, if it is a time zone during which sunlight such as night is not irradiated (step S170: Yes), the light emission control unit 390 performs step. The process proceeds to S180.

  Although the photovoltaic power generation unit 20 is not in the power generation state (step S110: No), the light emission control unit 390 has a certain remaining amount of the power storage device 10 with respect to the power consumption of the important load 50 (step S160: Yes). When the solar power generation unit 20 can be expected to generate power during the daytime or the like (step S170: No), the process proceeds to step S150. In such a step S150, the photovoltaic power generation unit 20 is in a state where power generation is temporarily stopped due to deterioration of sunshine conditions such as deterioration of weather or a solar panel being a shadow of a building. Therefore, when the process proceeds to step S150, the power consumption of the important load 50 is covered by the power storage device 10 having a remaining amount equal to or greater than a certain amount until the deterioration of the sunshine condition is improved (temporarily). Therefore, in this case, until the deterioration of the sunshine condition is improved and the power generation of the solar power generation unit 20 is resumed, the discharge power of the power storage device 10 is suppressed from increasing without using the outlet 356 with the notification unit. It is desirable. Therefore, the light emission control unit 390 lights the notification unit 360 in yellow and notifies that it is better to refrain from using the outlet 356 with the notification unit.

  In step S180, where the current time is a time zone from 17:00 to 6:00 in step S170, the light emission control unit 390 turns on the notification unit 360 in red. The light emission control unit 390, when the remaining amount of the power storage device 10 is greater than or equal to the power consumption of the important load 50 (step S160: Yes), but is not expected to generate power from the solar power generation unit 20 at night (step S160). (S110: No, step S170: Yes), the process proceeds to step S180. In this case, since it is necessary to cover the power of the important load 50 with the power storage device 10 alone until the sun rises (for a while), it is desirable that there is not much power and the use of the outlet 356 with a notification unit is avoided.

  For this reason, the light emission control part 390 judges that there is not much remaining power when it transfers to step S180, and makes the alerting | reporting part 360 light red (it controls to the light emission aspect different from step S140 * S150). This notifies that it is better to refrain from using the outlet 356 with the notification unit. When the process of step S180 ends, the light emission control unit 390 ends the light emission mode control process.

  In step S190, which shifts to the case where the supply available time H is 2.0 hours or less in step S160, the light emission control unit 390 causes the notification unit 360 to blink red. If the photovoltaic power generation unit 20 is not in the power generation state (step S110: No) and the remaining amount of the power storage device 10 is less than the power consumption of the important load 50 (step S160: No), the light emission control unit 390 is performed in step S190. Migrate to In this case, since the power storage device 10 with a small remaining amount covers the power consumption of the important load 50, there is no margin in power, and there is a possibility that the power supply to the important load 50 will be interrupted soon. For this reason, it is desirable to refrain from using the outlet 356 with a notification unit as much as possible, and to use power only to maintain the operation of the minimum necessary equipment (such as the refrigerator 52a) even during a power failure.

  For this reason, the light emission control part 390 judges that there is no remaining power when it transfers to step S190, and blinks the alerting | reporting part 360 in red (it controls to the light emission aspect different from step S140 * S150 * S180). This notifies that it is better to refrain from using the outlet 356 with the notification unit as much as possible. When the process of step S190 ends, the light emission control unit 390 ends the light emission mode control process.

  The process of controlling the light emission mode configured as described above is continuously performed unconditionally after the end, or triggered by a predetermined condition (for example, when a predetermined time has elapsed since the process ended) To) again. Note that the process of controlling the light emission mode is not necessarily performed a plurality of times, and may be performed only once during a power failure.

  By controlling the light emission mode of the notification unit 360 as described above, the light emission control unit 390 can notify whether the use of the outlet 356 with the notification unit should be refrained in the event of a power failure (step). S140, S150, S180, S190). According to this, it can be appropriately determined whether or not the use of the outlet 356 with the notification unit should be refrained. Specifically, for example, the light emission control unit 390 turns on the notification unit 360 in blue when there is a margin in power (step S140), and recognizes that it is not necessary to refrain from using the outlet 356 with the notification unit. be able to. Thereby, since a favorite apparatus can be used at the time of a power failure, the convenience can be improved. Moreover, the light emission control part 390 can alert | report the use of the outlet 356 with an alerting | reporting part as much as possible by blinking the alerting | reporting part 360 in red, when there is not enough power (step S190). Thereby, it can suppress that the power consumption of the important load 50 increases by use of the outlet socket 356 with an alerting | reporting part, and can suppress that the electric power supply to the important load 50 stops in a short time.

  Moreover, the light emission control part 390 can grasp | ascertain how much electric power can be supplied to the important load 50 by the electrical storage apparatus 10 single-piece | unit by calculating the supply possible time H by step S120 * S160. By changing the light emission mode of the notification unit 360 in consideration of such a supplyable time H, it is possible to appropriately notify whether or not the use of the outlet 356 with the notification unit should be refrained during a power failure.

  Moreover, the light emission control part 390 performs the present supply by the arithmetic processing (the said Formula (1)) using the information (The generated electric power G of the solar power generation part 20, etc.) acquired from the electrical storage apparatus 10 in step S120 * S160. Electric power K is calculated. According to this, it is not necessary to provide a sensor for detecting the power consumption of the important load 50 in order to acquire the current supply power K. Further, the current power supply K can be acquired using the function of the power storage device 10 that can operate even during a power failure. For this reason, the current supply power K can be easily acquired.

  Moreover, the light emission control part 390 changes the step which transfers according to whether the solar power generation part 20 is generating electric power in step S110, and considers the electric power generation state of the solar power generation part 20, and the alerting | reporting part 360. The light emission mode can be changed. Further, by considering the power generation state of the photovoltaic power generation unit 20 and changing the time to be compared with the supply available time H (steps S120 and S160), the light emission mode is more appropriately controlled in consideration of the supply available time H. be able to. Accordingly, it is possible to appropriately notify whether or not the use of the outlet 356 with the notification unit should be refrained during a power failure.

  Moreover, the light emission control part 390 can change the light emission mode of the alerting | reporting part 360 in consideration of the fluctuation | variation of the residual amount of the electrical storage apparatus 10 by changing the step which transfers in step S130 according to the state of the electrical storage apparatus 10. FIG. it can. Accordingly, it is possible to appropriately notify whether or not the use of the outlet 356 with the notification unit should be refrained during a power failure.

As described above, in the power supply system 301 according to the second embodiment,

Can be notified. In the present embodiment, by changing the light emission mode according to the supplyable time H calculated using the remaining amount Q of the power storage device 10 (storage battery) in steps S120 and S160, the power storage device 10 (storage battery) The light emission mode is indirectly controlled according to the remaining amount.

The light emission control unit 390 (control unit) calculates a supplyable time H based on the remaining amount Q of the power storage device 10 (storage battery) and the current supply power K. Is.

  With such a configuration, when the notification unit 360 is controlled, it is possible to grasp how much power can be supplied to the important load 50 by the power storage device 10 alone, so the use of the outlet 356 with the notification unit during a power failure It is possible to appropriately notify whether or not to refrain.

  Moreover, in this embodiment, although the light emission control part 390 was provided integrally with the outlet socket 356 with an alerting | reporting part, it is not limited to this. The light emission control unit 390 may be provided separately from the outlet 356 with a notification unit.

  Further, in the present embodiment, the light emission control unit 390 operates the notification unit 360 in four light emission modes, but the number of light emission modes controlled by the light emission control unit 390 is limited to this as long as it is two or more. It is not a thing. In addition, the light emission control part 390 can simplify the content to alert | report by operating the alerting | reporting part 360 by 2-4 light emission modes, and recognizes whether the use of the outlet 356 with an alerting | reporting part should be refrained. It can be made easy.

  The means for acquiring the current supply power K is not limited to the present embodiment. For example, the current supply power K can be obtained by acquiring a detection result from a sensor that detects the power consumption of the important load 50. The power K may be acquired.

  Further, the method for calculating the current supply power K is not limited to the present embodiment (the above formula (1)). For example, the current supply power is excluded by excluding the power consumption at the outlet 356 with the notification unit. K may be calculated.

  Moreover, if the time slot | zone compared with the present | current time in step S170 is a time slot | zone which can judge whether the solar power generation part 20 can generate | occur | produce electric power, it is between 17:00 to 6:00 like this embodiment. It is not limited to the time zone. In addition, the time zone to be compared with the current time in step S170 does not necessarily have to be a static value (fixed value), for example, a dynamic value that varies depending on the sunrise time and sunset time according to the current date. (Variable value).

  Moreover, although the light emission control part 390 shall acquire the electric power generation etc. of the solar power generation part 20 from the electrical storage apparatus 10, it is not limited to this, Devices (for example, solar power generation part) other than the electrical storage apparatus 10 20) or the like, the generated power of the solar power generation unit 20 may be acquired.

  In addition, as long as the communication unit 380 can communicate with the power storage device 10 and a light emission control unit 390 described later, the communication unit is not limited to the wireless LAN, and for example, a wired LAN can be used.
