The present invention relates to a power supply structure and a power supply system.

Patent Document 1 below discloses a power supply system that can supply power from an on-board battery to a building in an emergency by connecting the vehicle and the building with a power line. The power supply system in Patent Document 1 below is also configured to stop supplying power to the building when the remaining capacity of the on-board battery falls below a predetermined value.

JP 2009-278776 A

However, when power is supplied from an on-board battery to a building, the amount of power that can be supplied is limited, so power may only be supplied to some of the electrical loads in the building (electrical appliances such as home appliances and lighting fixtures). In this case, the residents of the building can only use some of the electrical loads, which significantly reduces convenience in an emergency.

The present invention takes into consideration the above facts and aims to provide a power supply structure and a power supply system that can supply power to a building from an external power source other than a commercial power source, and that can ensure convenience even in emergencies.

The power supply structure according to the first aspect includes an external power supply connection unit provided in a building to which an external power supply other than a commercial power supply is connected, a power supply path switching unit to which an emergency power supply path from the external power supply connection unit and a normal power supply path from a commercial power supply are connected and which is configured to be able to switch between the emergency power supply path and the normal power supply path, a plurality of indoor wirings that respectively connect the power supply path switching unit to a plurality of electrical loads in the building, and a power supply target switching unit that switches the indoor wirings to which power is supplied from the emergency power supply path.

In the power supply structure according to the first aspect, an external power supply connection unit is provided in the building, and an external power supply other than the commercial power supply is connected to this external power supply connection unit. In addition, an emergency power supply path from the external power supply connection unit and a normal power supply path from the commercial power supply are connected to the power supply path switching unit. Here, the power supply path switching unit is configured to be able to switch between the emergency power supply path and the normal power supply path. As a result, in the event of a power outage due to a disaster or the like and power cannot be supplied to the building from the normal power supply path, the power supply path switching unit can switch the power supply path to the emergency power supply path, thereby making it possible to supply power from the external power supply to the building.

In addition, in the power supply structure, the power supply path switching unit and multiple electrical loads in the building are each connected by indoor wiring, and the power supply target switching unit is configured to be able to switch the indoor wiring that supplies power from the emergency power supply path. This makes it possible to use a wide range of electrical appliances by switching the power supply destination, even if the amount of power that can be supplied is limited.

The power supply structure according to the second aspect is the first aspect, in which the external power supply connection portion is configured to be electrically connectable to an accessory outlet of the vehicle.

In the power supply structure according to the second aspect, power can be supplied from the accessory outlet of the vehicle to the building. This means that even a hybrid vehicle (HV) that does not have a charging port can supply power to the building if it has an accessory outlet.

The power supply structure according to the third aspect is provided with a power supply destination display unit that displays the room or the electrical load to which power can be supplied by the power supply target switching unit in the first or second aspect.

In the power supply structure according to the third aspect, the power supply destination display unit displays the rooms or electrical loads to which power can be supplied, so the user can know the available electrical loads simply by looking at the power supply destination display unit.

The power supply structure according to the fourth aspect is any one of the first to third aspects, in which the power supply target switching unit switches the power supply target for each room divided within the building.

In the power supply structure according to the fourth aspect, the power supply target can be switched for each room in the building, so that, for example, the living room can be the power supply target area during the day and the bedroom can be the power supply target area at night.

The power supply system according to the fifth aspect includes a power supply structure according to any one of the first to third aspects, and a control unit that electrically controls the switching by the power supply target switching unit, and the control unit switches the power supply target switching unit so that power can be supplied to the electrical load in the room specified by the user.

In the power supply structure according to the fifth aspect, the power supply target switching unit can switch the rooms to which power can be supplied (power supply target areas) in response to a signal from the control unit. This eliminates the need for the user to manually switch the power supply target areas.

In the power supply structure according to the sixth aspect, in the fifth aspect, the control unit includes a power supply target acquisition unit that acquires the names of the electrical loads stored in advance, and switches the power supply target switching unit so that power can be supplied to the electrical load corresponding to the name selected by the user as the power supply target.

In the power supply structure according to the sixth aspect, for example, if the name of an electrical appliance is stored for each electrical load, the user can simply select the name of the electrical appliance they wish to use and the power supply path can be switched so that power is supplied to that electrical appliance.

The power supply structure according to the seventh aspect is the fifth aspect, which includes a human presence sensor that detects a person in a building, and the control unit switches the power supply target switching unit so that power can be supplied to the electrical load in a room in which a person is detected based on a signal from the human presence sensor.

In the power supply structure according to the seventh aspect, the user can use electrical equipment in the room in which he or she is present without having to switch the power supply area himself or herself.

As described above, the power supply structure and power supply system of the present invention can ensure convenience even in emergencies.

First Embodiment
A power supply system 10 including a power supply structure according to a first embodiment will be described with reference to the drawings.

As shown in FIG. 1, the building 12 to which the power supply system 10 of this embodiment is applied is, for example, a modular building assembled using multiple building units, and is configured to include a building body 14 and a roof 16.

The building body 14 is composed of a first floor and a second floor, and in this embodiment, as an example, the first floor is a living/dining/kitchen 14A (hereinafter referred to as "LDK 14A").

The second floor of the main building 14 includes a bedroom 14B and a study 14C. Although not shown, the main building 14 also includes a toilet, bathroom, and other facilities necessary for daily life.

Here, the building body 14 is provided with an external power supply connection section 18 to which an external power supply other than a commercial power supply is connected. The external power supply connection section 18 is provided on the outer wall of the building body 14, and in this embodiment, as an example, the external power supply connection section 18 is configured by a waterproof flange inlet.

One end of a cable 20 is connected to the external power supply connection portion 18. The other end of the cable 20 is connected to a vehicle V as an external power supply. The vehicle V is a hybrid vehicle (HV) that is driven by an engine and a motor, and is equipped with a battery as a storage battery.

Here, an AC 100V accessory outlet is provided inside the vehicle V, and the other end of the cable 20 is connected to the accessory outlet. Then, with the building 12 and the vehicle V connected by the cable 20, the vehicle V is operated under specified conditions, such as in an emergency, to supply power from the vehicle V to the building 12. Even when the vehicle V is supplying power to the building 12, power is generated by starting the engine of the vehicle V, and the generated power is supplied to the battery of the vehicle V. In this way, it is configured to be possible to supply power to the building 12 for a long period of time.

Note that vehicle V is not limited to a hybrid vehicle, and may be any vehicle capable of supplying power to building 12, other than a hybrid vehicle. For example, vehicle V may be an electric vehicle (EV) or a fuel cell vehicle (FCV).

The external power source is not limited to the vehicle V, but may be a generator or the like.

One end of the first power line 22A is connected to the external power supply connection unit 18, and the other end of the first power line 22A is connected to the power supply target switching unit 24. Details of the power supply target switching unit 24 will be described later.

One end of the second power line 22B and one end of the third power line 22C are connected to the power supply target switching unit 24. The other end of the second power line 22B is connected to the LDK switching unit 30, which serves as a power supply path switching unit. The other end of the third power line 22C is connected to the bedroom switching unit 32, which serves as a power supply path switching unit.

Meanwhile, a distribution board 26 is provided in the building body 14. A power transmission line 28 is connected to the distribution board 26, and commercial power (grid power) is supplied to the building 12 from a commercial power source (not shown) via this power transmission line 28.

One end of the fourth power line 22D and one end of the fifth power line 22E are connected to the distribution board 26. The other end of the fourth power line 22D is connected to the LDK switching unit 30. The other end of the fifth power line 22E is connected to the bedroom switching unit 32.

As described above, the LDK switching unit 30 is connected to an emergency power supply path from the vehicle V via the first power line 22A and the second power line 22B. In addition, the LDK switching unit 30 is connected to a normal power supply path from a commercial power source via the fourth power line 22D. On the other hand, the bedroom switching unit 32 is connected to an emergency power supply path from the vehicle V via the first power line 22A and the third power line 22C. In addition, the bedroom switching unit 32 is connected to a normal power supply path from a commercial power source via the fifth power line 22E.

Here, the LDK switching unit 30 is connected to an LDK unit cable 34 as indoor wiring, and the LDK unit cable 34 is wired to each electrical load in the LDK 14A. As an example, FIG. 1 shows a state in which the LDK unit cable 34 is wired to a television 40, lighting fixture 42, outlet 44, refrigerator 46, and induction heater 48.

The LDK switching unit 30 is also configured to be able to switch between an emergency power supply path and a normal power supply path. Specifically, the LDK switching unit 30 is equipped with a switch, and is able to switch between an "emergency state" in which the power supply target switching unit 24 and the LDK unit cable 34 are connected to supply power from the emergency power supply path, and a "normal state" in which the distribution board 26 and the LDK unit cable 34 are connected to supply power from the normal power supply path.

The bedroom switching unit 32 is connected to a bedroom unit cable 36 as indoor wiring, and the bedroom unit cable 36 is wired to each electrical load in the bedroom 14B. As an example, FIG. 1 shows the state where the cable is wired to a lighting fixture 50 and an outlet 52.

The bedroom switching unit 32 is also configured to be able to switch between an emergency power supply path and a normal power supply path. Specifically, the bedroom switching unit 32 is equipped with a switch and is able to switch between an "emergency state" in which the power supply target switching unit 24 and the bedroom unit cable 36 are connected to supply power from the emergency power supply path, and a "normal state" in which the distribution board 26 and the bedroom unit cable 36 are connected to supply power from the normal power supply path.

The LDK switching unit 30 and the bedroom switching unit 32 are configured to switch at the same time. Therefore, if the supply of power from the commercial power source is stopped during a power outage, both the LDK switching unit 30 and the bedroom switching unit 32 can be switched from the "normal state" to the "emergency state" to supply power from the vehicle V to the building 12 via the emergency power supply path.

For ease of explanation, FIG. 1 only illustrates the wiring for the living room, dining room, and kitchen 14A and bedroom 14B. However, the study 14C is also similarly wired so that the emergency power supply path and normal power supply path can be switched, and a study switching unit (not shown) is provided.

(Power supply target switching unit 24)
Next, the power supply target switching unit 24 in this embodiment will be described in detail. The power supply target switching unit 24 in this embodiment is connected to the LDK switching unit 30 and the bedroom switching unit 32. Although not shown, the power supply target switching unit 24 is also connected to a study switching unit that serves as a power supply path to the study 14C.

Here, the power supply target switching unit 24 is equipped with a switch, and is configured to be able to switch the power supply destination of the power supplied from the vehicle V via the first power line 22A between the living/dining/kitchen area switching unit 30, the bedroom switching unit 32, and the study switching unit. In other words, the power supply target switching unit 24 is configured to be able to switch the power supply destination to which power is supplied from the emergency power supply path for each room separated within the building 12.

In addition, in the initial state, the power supply target switching unit 24 sets the position of the switch so that the LDK 14A in which the refrigerator 46 is installed is the power supply destination. Here, in this embodiment, the switching of the switch in the power supply target switching unit 24 is electrically controlled by the control unit 60 (see FIG. 3) constituting the power supply system 10.

(Hardware configuration of power supply system 10)
3, the control unit 60 constituting the power supply system 10 of the present embodiment is configured to include a CPU (Central Processing Unit: processor) 62, a ROM (Read Only Memory) 64, a RAM (Random Access Memory) 66, a storage 68, a communication interface 70, and an input/output interface 72. Each component is connected to each other via a bus 74 so as to be able to communicate with each other.

The CPU 62 is a central processing unit that executes various programs and controls each part. That is, the CPU 62 reads out a program from the ROM 64 or storage 68, and executes the program using the RAM 66 as a working area. The CPU 62 controls each of the above components and performs various calculation processes according to the program recorded in the ROM 64 or storage 68.

The ROM 64 stores various programs and various data. The RAM 66 temporarily stores programs or data as a working area. The storage 68 is a non-temporary recording medium configured with an HDD (Hard Disk Drive) or SSD (Solid State Drive) that stores various programs including an operating system and various data. In this embodiment, the ROM 64 or the storage 68 stores a program for executing the power supply target cut-off process, etc.

The communication interface 70 is an interface through which the control unit 60 communicates with external devices via the network N, and uses standards such as 5G, LTE, Wi-Fi (registered trademark), and Ethernet (registered trademark). In this embodiment, the communication interface 70 enables the control unit 60 to communicate with a mobile terminal 89 that serves as a power supply destination display unit. The mobile terminal 89 is, for example, a smartphone carried by a user of the building 12, and by starting a specific application from this mobile terminal 89, the electrical loads to which power can be supplied are displayed.

The input/output interface 72 is connected to a display device 76 as a power supply destination display unit, an input device 78, a power supply target switching unit 24, an LDK switching unit 30, and a bedroom switching unit 32. The display device 76 is configured to include, for example, a monitor installed inside the building 12, and displays the electrical loads that can be supplied with power.

The input device 78 is a device that allows the user to input information to the control unit 60, and is configured to include, for example, a touch panel unit mounted on a monitor installed in the room. That is, in this embodiment, a touch panel monitor is provided in the room of the building 12, and this monitor has the functions of the display device 76 and the input device 78.

The power supply target switching unit 24, the living room/dining room/kitchen area switching unit 30, and the bedroom switching unit 32 are each configured so that the switching switch is switched by a signal from the control unit 60.

(Functional configuration of power supply system 10)
The power supply system 10 uses the above hardware resources to realize various functions. The functional configuration realized by the power supply system 10 will be described with reference to FIG.

As shown in FIG. 4, the power supply system 10 is configured to include, as functional components, an external power source connection confirmation unit 80, a route switching unit 81, an instruction receiving unit 82, a power supply target area switching unit 83, and a display control unit 84. Each functional component is realized by the CPU 62 reading and executing a program stored in the ROM 64 or storage 68.

The external power supply connection confirmation unit 80 confirms that an external power supply has been connected. Specifically, sensors that detect that the cable 20 has been connected are provided in the external power supply connection unit 18 in FIG. 1, and the external power supply connection unit 18 confirms that an external power supply has been connected based on signals from the sensors.

The route switching unit 81 switches between the emergency power supply path and the normal power supply path. Specifically, the route switching unit 81 switches the switches of the LDK switching unit 30 and the bedroom switching unit 32 from the "normal state" to the "emergency state." Similarly, in the event of a power outage, the route switching unit 81 switches the switch of the study switching unit from the "normal state" to the "emergency state."

Here, the path switching unit 81 may automatically switch each changeover switch from the "normal state" to the "emergency state" when a power outage is detected. Also, the path switching unit 81 may automatically switch each changeover switch from the "normal state" to the "emergency state" when the external power connection confirmation unit 80 confirms that an external power source is connected. As an example in this embodiment, when a power outage is detected and/or when an external power source is connected to the external power connection unit 18, the path switching unit 81 switches each changeover switch from the "normal state" to the "emergency state".

The instruction receiving unit 82 receives instructions from a user. Specifically, the instruction receiving unit 82 receives an instruction to switch the power supply target area from the user via the input device 78 or the mobile terminal 89.

The power supply target area switching unit 83 switches the power supply target area for each room divided within the building 12. Specifically, the power supply target area switching unit 83 switches the switch of the power supply target switching unit 24 in response to a user instruction received by the instruction receiving unit 82. This switches the power supplied from the vehicle V via the first power line 22A to flow to the power supply target area specified by the user.

The display control unit 84 performs various displays on the display device 76 and the mobile terminal 89, which are the power supply destination display units. For example, the display control unit 84 displays the power supply target area to which power can be supplied on the display device 76 and the mobile terminal 89. Below, a display example in which the power supply target area is displayed on the mobile terminal 89 is described.

As shown in FIG. 2, the display area of the mobile terminal 89 displays an icon M1 corresponding to the living/dining/kitchen area 14A, an icon M2 corresponding to the study 14C, and an icon M3 corresponding to the bedroom 14B. The display in FIG. 2 may be configured to be displayed, for example, by starting a specific application on the mobile terminal 89. In addition, text providing guidance on selecting a power supply destination may be displayed.

In the state shown in FIG. 2, the display control unit 84 functions to display the icon M1 in a manner different from the display manner of the icons M2 and M3. In this embodiment, the selected icon M1 is displayed inverted. By changing the display manner in this way, it is shown that the LDK 14A corresponding to the icon M1 is a target area for power supply.

In addition, in the state shown in FIG. 2, if the user selects (touches) icon M3 corresponding to bedroom 14B, the inverted display of icon M1 is cancelled and icon M3 is displayed inverted. Furthermore, an instruction to switch bedroom 14B to the power supply target area is received by instruction receiving unit 82, and the power supply target area switching unit 83 switches the switch of power supply target switching unit 24 from LDK switching unit 30 to bedroom switching unit 32. This makes it possible to use the lighting fixture 50 and outlet 52 in bedroom 14B.

(Action)
Next, the operation of this embodiment will be described.

(Example of power supply target switching process)
5 is a flowchart showing an example of the flow of the power supply target switching process by the power supply system 10. This power supply target switching process is executed by the CPU 62 reading a program from the ROM 64 or the storage 68, deploying it in the RAM 66, and executing it. Note that the power supply target switching process described below is executed in a state in which the supply of commercial power is stopped due to a power outage.

5, in step S102, the CPU 62 determines whether an external power source is connected to the external power source connection unit 18. In this embodiment, the CPU 62 determines whether a vehicle V is connected to the external power source connection unit 18. The CPU 62 acquires signals from sensors that detect that the cable 20 is connected, using the function of the external power source connection confirmation unit 80. If the external power source connection confirmation unit 80 confirms that the cable 20 is connected to the vehicle V, the CPU 62 proceeds to processing in step S104. On the other hand, if the external power source connection confirmation unit 80 does not confirm that the cable 20 is connected to the vehicle V, that is, if the sensors do not detect the connection between the vehicle V and the cable 20, the CPU 62 ends the power supply target switching process.

The CPU 62 checks the power supply path in step S104. Specifically, the CPU 62 acquires signals from the LDK switching unit 30, the bedroom switching unit 32, and the study switching unit. In this embodiment, in the event of a power outage or when the vehicle V is connected to the external power supply connection unit 18, each changeover switch is automatically switched to the "emergency state" by the path switching unit 81. Therefore, the CPU 62 checks in step S104 that each changeover switch is switched to the "emergency state."

Next, in step S106, the CPU 62 checks whether or not power supply is possible. Specifically, the CPU 62 determines whether or not the switches of the LDK switching unit 30, the bedroom switching unit 32, and the study switching unit are switched to the "emergency state" and whether or not the accessory outlet of the vehicle V is ON.

If the changeover switches are in the "emergency state" in step S106 and the accessory outlet of the vehicle V is ON, the CPU 62 determines that power supply is possible and proceeds to processing in step S108.

On the other hand, if some of the switches are in the "normal state" in step S106 or if the accessory outlet is OFF, the CPU 62 determines that power supply is not possible and proceeds to step S110. The CPU 62 displays a message on the display device 76 and the mobile terminal 89 in step S110. For example, if the switch of the LDK switching unit 30 is in the "normal state," the CPU 62 uses the function of the display control unit 84 to display a message on the display device 76 and the mobile terminal 89 urging the user to check the LDK switching unit 30. Also, for example, if the accessory outlet of the vehicle V is OFF, the CPU 62 uses the function of the display control unit 84 to display a message on the display device 76 and the mobile terminal 89 urging the user to turn on the accessory outlet.

When the CPU 62 moves from step S106 to step S108, it displays the power supply target area on the display device 76 and the mobile terminal 89. In the initial state, the changeover switch is set to a position such that power is supplied to the LDK 14A, so the display on the mobile terminal 89 is as shown in FIG. 2.

Next, in step S112, the CPU 62 determines whether or not an instruction to switch the power supply target area has been received. Specifically, when the CPU 62 receives an instruction to switch the power supply target area from the user via the input device 78 or the mobile terminal 89 through the function of the instruction receiving unit 82, it determines that a switching instruction has been received and proceeds to the process of step S114. On the other hand, when a switching instruction has not been received from the user, the CPU 62 returns to step S108.

In step S114, the CPU 62 switches the power supply target area and changes the display on the display device 76 and the mobile terminal 89. Specifically, the CPU 62 uses the function of the power supply target area switching unit 83 to switch the switch of the power supply target switching unit 24 in response to the user's instruction received in step S112. In addition, the CPU 62 displays the switched power supply target area on the display device 76 and the mobile terminal 89 in step S114. Then, the power supply target switching process ends.

As described above, in this embodiment, the LDK switching unit 30 and the bedroom switching unit 32 are configured to be able to switch between the emergency power supply path and the normal power supply path. This allows power to be supplied to the building 12 from an external power source such as a vehicle V via the emergency power supply path even in the event of a power outage and the building being unable to be supplied with power from the normal power supply path.

In addition, in this embodiment, the power supply target switching unit 24 is configured to be able to switch the power supply destination to which power is supplied from the emergency power supply path. As a result, even if the amount of power that can be supplied from an external power source is limited, a wide range of electrical appliances can be used by switching the power supply destination. As a result, convenience can be ensured even in an emergency.

In particular, in this embodiment, the power supply target area is switched by a signal from the control unit 60, eliminating the need for the user to manually switch the power supply target area.

Furthermore, in this embodiment, the vehicle V is configured to be able to supply power to the building 12 from an accessory outlet. This allows even a hybrid vehicle (HV) that does not have a charging port to supply power to the building 12.

Furthermore, in this embodiment, the rooms to which power can be supplied are displayed on the display device 76 and the mobile terminal 89, so that the user can ascertain the available electrical load simply by looking at the display device 76 or the mobile terminal 89.

In addition, in this embodiment, the power supply target can be switched for each room in the building 12, so that, for example, a room such as the living/dining/kitchen area 14A can be the power supply target area during the day, and a room such as the bedroom 14B can be the power supply target area at night.

(Modification)
Next, a modification of the power supply structure according to the first embodiment will be described with reference to Fig. 6. In this modification, the wiring for supplying power is partially different.

As shown in FIG. 6, in this modified example, one end of the first power line 23A is connected to the external power supply connection portion 18, and the other end of the first power line 23A is connected to a vehicle connection device 85. The vehicle connection device 85 has built-in sensors that detect the connection of a vehicle V.

One end of the second power line 23B is connected to the vehicle connection device 85, and the other end of the second power line 23B is connected to the power supply path switching unit 86. This power supply path switching unit 86 is connected to the distribution board 26 via the third power line 23C, and is configured to be able to switch between the emergency power supply path and the normal power supply path by a changeover switch.

One end of the fourth power line 23D is connected to the terminal on the emergency power supply path side of the power supply path switching unit 86, and the other end of the fourth power line 23D is connected to the power supply target switching unit 88. Here, the power supply target switching unit 88 has a changeover switch and is configured to be able to switch the power supply target area to which power is supplied from the emergency power supply path. As an example, the power supply target switching unit 88 of this modified example can switch between a path toward the LDK unit cable 34 and a path toward the bedroom unit cable 36.

On the other hand, one end of the fifth power line 23E is connected to the terminal on the normal power supply path side of the power supply path switching unit 86, and the other end of the fifth power line 23E is connected to the LDK unit cable 34 and the bedroom unit cable 36.

As this modified example is configured as described above, the changeover switch of the power supply path switching unit 86 is normally set to the normal power supply path. In this state, the terminal on the third power line 23C side that connects the distribution board 26 and the terminal on the fifth power line 23E side are electrically connected.

In addition, in the event of an emergency, the changeover switch of the power supply path switching unit 86 is automatically or manually switched to the emergency power supply path, electrically connecting the terminal on the second power line 23B side connecting the vehicle connection device 85 to the fourth power line 23D extending to the power supply target switching unit 88 (the state shown in FIG. 6).

Then, when the emergency power supply path is selected, the power supply target area can be switched by switching the power supply target switching unit 88. In this manner, in this modified example, the number of power supply target switching units 88 can be reduced compared to the above embodiment.

Second Embodiment
Next, a power supply system 90 including a power supply structure according to a second embodiment will be described with reference to the drawings. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted as appropriate.

The overall configuration and hardware configuration of the power supply system 90 in this embodiment are the same as those of the first embodiment shown in Figures 1 and 3. Here, in the power supply system 90 of this embodiment, a changeover switch (not shown) is provided in the LDK unit cable 34 and the bedroom unit cable 36 in Figure 1. And, it differs from the first embodiment in that the changeover switch provided in the LDK unit cable 34 can switch the power supply target from among the individual electrical loads in the LDK 14A (television 40, lighting fixture 42, outlet 44, refrigerator 46, and induction heater 48). Similarly, the changeover switch provided in the bedroom unit cable 36 can switch the power supply target from among the individual electrical loads in the bedroom 14B (lighting fixture 50 and outlet 52).

(Functional configuration of power supply system 90)
The power supply system 90 realizes various functions using the hardware resources shown in Fig. 3. The functional configuration realized by the power supply system 90 will be described with reference to Fig. 4.

As shown in FIG. 7, the power supply system 90 is configured to include, as functional components, an external power supply connection confirmation unit 80, a path switching unit 81, an instruction receiving unit 82, a power supply target acquisition unit 91, a power supply target device switching unit 92, and a display control unit 84. Each functional component is realized by the CPU 62 reading and executing a program stored in the ROM 64 or storage 68.

The power supply target acquisition unit 91 acquires the names of each of the pre-stored electrical loads. For example, a user may register in advance a combination of an indoor outlet identification number and an electrical load connected to the outlet, and the combination is stored in the storage 68 or the like. The power supply target acquisition unit 91 acquires data from the storage 68 or the like, and acquires information on the electrical load connected to each outlet. Furthermore, based on the combination acquired by the power supply target acquisition unit 91, the display control unit 84 displays on the display device 76 and the mobile terminal 89.

In the example display shown in FIG. 8, some of the devices registered as electrical loads are displayed. Here, icon M4 corresponding to refrigerator 46, icon M5 corresponding to television 40, icon M6 corresponding to lighting fixture 42, and icon M7 corresponding to induction heater 48 are displayed as electrical devices in LDK 14A.

The power supply target device switching unit 92 in FIG. 7 switches the changeover switch in response to the user's instruction received by the instruction receiving unit 82, thereby allowing the power supplied from the vehicle V to flow to the power supply target device specified by the user.

For example, in the display example of FIG. 8, the refrigerator 46 and the lighting fixture 42 are specified as the power supply destinations. In this case, the power supply target device switching unit 92 sets the changeover switch of the power supply target switching unit 24 to the LDK switching unit 30 side. The power supply target device switching unit 92 also switches the changeover switch provided on the LDK unit cable 34 so that power is supplied to the refrigerator 46 and the lighting fixture 42. In this way, in this embodiment, it is possible to supply power to the electrical loads corresponding to the names selected by the user as the power supply destinations.

(Action)
Next, the operation of this embodiment will be described.

In the power supply system 90 of this embodiment, for example, if the name of an electrical appliance is stored for each electrical load, the user can simply select the name of the electrical appliance they want to use to switch the power supply path so that power is supplied to the electrical appliance. Other operations are the same as those of the first embodiment.

The power supply systems 10 and 90 according to the first and second embodiments have been described above, but it goes without saying that the present invention can be embodied in various forms without departing from the spirit and scope of the present invention. For example, in the above first embodiment, a configuration in which the power supply target area is switched in response to a user's instruction has been described, but the present invention is not limited to this, and a configuration in which the power supply target area is switched by detecting the user's position may also be adopted.

For example, a human presence sensor using an infrared sensor or the like may be used to detect the position of a user, and the power supply target switching unit may be switched so that power can be supplied to the electrical load in the room where a person is detected based on a signal from the human presence sensor. Also, instead of an infrared sensor, a human presence sensor may be used that detects people through image recognition using a camera or the like. In such a configuration, wiring may be arranged so that power is preferentially supplied from an external power source to the human presence sensor, regardless of the position of the changeover switch.

The power supply target switching unit may also be switched according to the time period or situation registered in advance by the user. For example, the power supply target switching unit may be configured to automatically switch so that the power supply target area is the living room or a room with poor light during the day, and the power supply target area is the bedroom at night.

Furthermore, the system may be configured to supply power to some electrical loads on a priority basis. For example, in the case of a long-term power outage, there is a risk that food inside refrigerator 46 may spoil, so the system may be configured to supply power to refrigerator 46 regardless of the power supply area.

Furthermore, in the second embodiment, the electrical loads that can be selected by the user may be displayed on the mobile terminal 89 or the like. For example, if power can be supplied up to 1500 W and the total power required for the electrical loads already selected by the user is close to 1500 W, only the electrical loads that can be used within a range not exceeding 1500 W may be displayed.

In addition, the processing that the CPU 62 executes by reading the software (program) in the above embodiment may be executed by various processors other than the CPU. Examples of processors in this case include PLDs (Programmable Logic Devices) such as FPGAs (Field-Programmable Gate Arrays) whose circuit configuration can be changed after manufacture, and dedicated electrical circuits such as ASICs (Application Specific Integrated Circuits), which are processors having a circuit configuration designed specifically to execute specific processing. The above processing may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, and a combination of a CPU and an FPGA). The hardware structure of these various processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor elements.

In addition, in the above embodiment, the storage 68 is the recording unit, but this is not limited to this. For example, the recording unit may be a non-transitory recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory. In this case, various programs may be stored in these recording media.
