Description

[Technical Field]

[0001] The present disclosure relates to an electric vehicle power supply control system, program, and method. [Background technology]

[0002] Efforts have been made to resolve the problems that arise when charging large-capacity storage batteries in electric vehicles such as electric vehicles (hereinafter referred to as "EVs") and plug-in hybrid vehicles (PHVs) using commercial power sources in the home (see Patent Document 1). Patent Document 1 discloses a distribution board device that gives top priority to current consumption required in the home, thereby avoiding the inconvenience of turning off electrical appliances that are normally used when charging the PHV / EV, and that can charge the PHV / EV with the maximum current within the remaining allowable current. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-125091 Summary of the Invention [Problem to be solved by the invention]

[0004] The distribution board device disclosed in Patent Document 1 determines whether the current consumption value is less than the allowable current value. If the current consumption value exceeds the allowable current value, the electromagnetic switch for the PHV / EV is opened, preventing the PHV / EV from charging and allowing power to be supplied to the home. If the current consumption value does not exceed the allowable current value, the electromagnetic switch is closed and the PHV / EV is charged at a current value Ic, which is the allowable current value Ib minus the current consumption value Ia. However, the controller 16 included in the distribution board device of Patent Document 1 merely determines whether the current consumption value Ia is less than the allowable current value Ib and controls whether or not to supply the current value Ic by opening and closing the electromagnetic switch 61. This does not allow for precise control of the current value Ic for charging electric vehicles such as PHVs / EVs. Furthermore, the controller 16 is configured to receive the output of the branch breakers for all loads (such as home appliances) and control the current supply to each load. However, using the controller 16 to supply current to loads such as home appliances would result in a complex structure and potentially high implementation costs. Furthermore, in recent years, charging via a power supply device dedicated to charging electric vehicles has become common, and there is a demand for a system that can precisely control the maximum supply power according to the power consumption within the target space while being compatible with such electric vehicle power supply devices.

[0005] Therefore, the present disclosure aims to provide an electric vehicle power supply control system, program, and method that can precisely set the maximum supply power in accordance with the power consumption and power generation within a target space using a control device or an electric vehicle power supply device, by providing a control device that transmits information for setting the maximum supply power in an electric vehicle power supply device that supplies power to an electric vehicle. [Means for solving the problem]

[0006] The electric vehicle power supply control system according to one aspect of the present invention is an electric vehicle power supply control system including a control device that transmits information for setting the maximum supply power in an electric vehicle power supply device that supplies power to an electric vehicle. The control device includes at least one of a target space power measurement unit that measures the target space consumption power supplied to a target space load, which is a load that consumes power in a target space, or a generated power measurement unit that measures the target space generated power generated by a power generation device included in the target space, and target space consumption power information indicating the target space consumption power, or target space generated power information indicating the target space generated power, or calculated power information calculated based on at least one of the target space consumption power or the target space generated power, or maximum supply power information indicating the maximum supply power, and a supply power control unit that transmits at least one of them to the electric vehicle power supply device.

Effect of the Invention

[0007] According to one aspect of the present invention, by providing a control device that transmits information for setting the maximum supply power in an electric vehicle power supply device that supplies power to an electric vehicle in particular, it is possible to provide an electric vehicle power supply control system, program, and method capable of finely setting the maximum supply power according to the consumption power and generated power in the target space by the control device and the electric vehicle power supply device.

[0011] <Configuration of the electric vehicle power supply control system 1 in the present invention> For example, FIG. 1 is a diagram showing a configuration example of an electric vehicle power supply control system 1 according to Embodiment 1. The electric vehicle power supply control system 1 in the present invention includes a control device 11, an electric vehicle power supply device 21, and an electric vehicle side power storage system 41.

[0012] The electric vehicle power supply control system 1 in the present invention includes a control device 11 that transmits information for setting the maximum supply power in the electric vehicle power supply device 21 that supplies power to the electric vehicle. The control device 11 includes a target space power measurement unit 113 that measures target space power consumption information indicating the target space power consumption supplied to a target space load 31 that is a load consuming power in the target space, or at least any one of a power generation power measurement unit 116 that measures the target space power generation generated by a power generation device provided in the target space, and (1) target space power consumption information indicating the target space power consumption, or (2) target space power generation information indicating the power generation power generated by a power generation device provided in the target space, or (3) calculated power information calculated based on at least any one of the target space power consumption and the target space power generation, (4) a supply power control unit 115 that transmits at least any one of maximum supply power information indicating the maximum supply power to the electric vehicle power supply device 21.

[0013] The electric vehicle power supply control system 1 of the present invention can be considered as a program as follows.

[0015] The electric vehicle power supply control system 1 of the present invention can be considered as a control method as follows.

[0016] A method for controlling an electric vehicle power supply control system (1) including a control device (11) that transmits information for setting a maximum supply power in an electric vehicle power supply device (21) that supplies power to an electric vehicle, the method comprising: a step by the control device (11) of measuring, by the control device (11), at least one of a step of measuring target space power consumption supplied to a target space load (31) that is a load that consumes power in the target space, or a step of measuring target space generated power generated by a power generation device provided in the target space; and a step of transmitting, to the electric vehicle power supply device (21), at least one of target space power consumption information indicating the target space power consumption, target space generated power information indicating the power generated by a power generation device provided in the target space, calculated power information calculated based on at least one of the target space power consumption or the target space generated power, and maximum supply power information indicating the maximum supply power.

[0018] <Embodiment 1>

[0019] <Configuration of the electric vehicle power supply control system 1 in Embodiment 1> FIG. 1 is a diagram showing a configuration example of the electric vehicle power supply control system 1 according to the first embodiment. The electric vehicle power supply control system 1 in the first embodiment includes a control device 11, an electric vehicle power supply device 21, and an electric vehicle side power storage system 41.

[0020] As shown in FIG. 1, the commercial power line E is attached to the utility pole EP by a mounting component (not shown). However, the commercial power line E may be buried underground without being attached to the utility pole EP. Commercial power flows through the commercial power line E.

[0021] One end of the power cable EC is connected to the commercial power line E so that commercial power can be energized. The other end of the power cable EC is connected to the power meter EM. The power meter EM is an electrical instrument that integrates and measures the power obtained through the power cable EC.

[0022] One end of the first power cable EC1 is connected to the power meter EM. A part of the first wiring W1 is drawn into the house HU and connected to the distribution board DB.

[0023] FIG. 2 is a diagram showing an example of the distribution board DB according to the first embodiment. The distribution board DB includes a main breaker MB, a leakage breaker ELB, and a branch breaker BB.

[0024] The main breaker MB is an incoming device and a protection device for commercial power. The main breaker MB detects the current throughout the target space and shuts off the circuit in case of an abnormality. The main breaker MB includes a power receiving section and a power supply section. The power receiving section may be a power receiving terminal. The power supply section may be a power supply terminal. The main breaker MB may be read as a service breaker. Commercial power is the electrical power supplied from a power plant to consumers (ordinary households and factories). The commercial power supplies in Japan are AC with voltages of 100V (mainly single-phase) and 200V (single-phase / three-phase).

[0025] The earth leakage breaker ELB is a device that shuts off the circuit when detecting earth leakage to prevent disasters. The earth leakage breaker ELB includes a power receiving section and a power supply section. The power receiving section may be a power receiving terminal. The power supply section may be a power supply terminal. The earth leakage breaker may be read as an earth leakage breaker or an ELCB (Earth Leakage Circuit Breaker).

[0026] The branch breaker BB is a device that shuts off only the circuit when electricity exceeding the capacity flows through a circuit (branch circuit) that carries electricity from a distribution board to each room or socket, preventing the electricity supply to the whole house from stopping. The branch breaker BB includes a power receiving section and a power supply section. The power receiving section may be a power receiving terminal. The power supply section may be a power supply terminal. The branch breaker BB may be read as a wiring cut-off safety breaker.

[0027] As shown in Figure 2, the other end of the first wiring W1 is connected to the power receiving section of the main breaker MB so that commercial power can be energized. Commercial power is composed of two wires, the 0V wire 0EL and the +100V wire +EL described later, or two wires, the 0V wire 0EL and the -100V wire -EL described later, for receiving about 100V. In addition to this case, it may be composed of two wires, the +100V wire +EL and the -100V wire -EL, for receiving 200V, or it may be composed of three wires, the +100V wire +EL, the -100V wire -EL, and the 0V wire 0EL, for receiving 100V or 200V. Note that the other wirings may have the same configuration.

[0028] The second wiring W2 has one end connected to the power supply section of the main breaker MB and the other end connected to the power receiving section of the earth leakage breaker ELB so that power can be energized.

[0029] The third wiring W3 has one end connected to the power supply section of the earth leakage breaker ELB and the other end connected to the power receiving section of the branch breaker BB so that power can be energized.

[0030] Two or more branch breakers BB form a branch breaker group BBG. Therefore, the third wiring W3 is connected to the power receiving sections of all the branch breakers BB included in the branch breaker group BBG (for the sake of simplification of the figure, in Fig. 2 etc., it is shown as being connected to one branch breaker BB).

[0031] The fourth wiring W4 has one end connected to the power supply section of the branch breaker BB so that power can be energized. Also, the fourth wiring W4 has a branch point SP at the other end. Two or more branch wirings SW have one end connected to the branch point SP of the fourth wiring W4 so that power can be energized, and all or part of the other ends are connected to the load 31 in the target space so that power can be supplied. The load 31 in the target space is a load that consumes the power in the target space, such as household appliances such as a TV, an air conditioner, a water heater, a lighting fixture, and a cooking appliance, and various things are included.

[0032] As shown in Fig. 1, two or more fourth wirings W4 form a fourth wiring group W4G (only one of the fourth wirings W4 from each branch breaker BB is shown for the sake of simplification, but this is not the case). Therefore, the fourth wiring group W4G includes two or more fourth wirings W4. When the first current sensor CS1 is provided in the fourth wiring group W4G, the first current sensor CS1 is connected to all the fourth wirings W4 included in the fourth wiring group W4G.

[0033] The first current sensor CS1 is a sensor that measures the current flowing through the wiring. The first current sensor CS1 may be composed of, for example, one or more clamp current measurement sensors. The first current sensor CS1 includes an information output unit for transmitting current data. The information output unit may be an information output terminal. Note that, although only the configuration in which the current sensor CS is connected to the wiring to be measured, such as the third wiring W3, is schematically shown in the figure, it may be a configuration in which it is connected to the wiring indicating the reference power (which may be 0V) for measuring the current (more specifically, for example, a configuration in which the reference power wiring is clamped). Also, the wiring to be measured is not limited to the third wiring W3 as described later, and may be any wiring such as, for example, the first wiring W1, the second wiring W2, the fourth wiring group W4G, the fifth wiring W5, and the seventh wiring W7 (that is, for the wiring for the load 31 in the target space, the wiring for the control device 11, and the wiring for the power supply device 21 for the electric vehicle, all or some of them may be provided with a common current sensor, or each may be provided with a current sensor). Note that, although a configuration in which the first current sensor CS1 (and the first voltage sensor VS1) is built in the distribution board DB is illustrated in FIG. 3, it is not limited to this, and each sensor may be provided on the wiring to be measured outside the distribution board DB.

[0034] One end of the fifth wiring W5 is connected to the seventh wiring W7 (or the power supply unit of the breaker EVB for the power supply device 21 for the electric vehicle) so that power can be energized, and the other end is connected to the power supply power receiving unit 111 of the control device 11. Also, not limited to this, the fifth wiring W5 may be, for example, a configuration in which one end is connected to any one or more of the fourth wirings W4 in the fourth wiring group W4G, and the other end is connected to the power supply power receiving unit 111 of the control device 11.

[0035] As shown in FIG. 2, one end of the sixth wiring W6 is connected to the third wiring W3 so that power can be energized, and the other end is connected to the power receiving part of the breaker EVB for the electric vehicle power supply device 21. Note that the connection configuration is not limited to this. For example, one end of the sixth wiring W6 may be connected in parallel with the third wiring W3 to the leakage breaker ELB. In this case, a configuration in which the first current sensor CS1 and the first voltage sensor VS1 are provided respectively may be adopted, or a configuration in which only the third wiring W3 is provided if only the power consumption of the load 31 in the target space is to be grasped.

[0036] One end of the seventh wiring W7 is connected to the power supply part of the breaker EVB for the electric vehicle power supply device 21 so that power can be energized, and the other end is connected to the power supply power receiving part 211 of the electric vehicle power supply device 21.

[0037] One end of the first communication cable CC1 is connected to the target space power measurement part 113 of the control device 11 so that current data can be transmitted from the first current sensor CS1 to the control device 11, and the other end is connected to the information output part of the first current sensor CS1.

[0038] The first current sensor CS1 transmits, as power data (which may also be called current data; since the voltage is generally approximately constant (e.g., 100V or 200V), it is also referred to as power data. The same applies hereinafter), at least any one of the current in the second wiring W2, the current in the third wiring W3, or the total current flowing through all the fourth wirings W4, the fifth wirings W5, and the seventh wiring W7 to the target space power measurement unit 113 of the control device 11 via the first communication cable CC1 (in the illustrated configuration, the first current sensor CS1 is connected to the third wiring W3). The current in the second wiring W2, the current in the third wiring W3, or the total current flowing through all the fourth wirings W4, the fifth wirings W5, and the seventh wiring W7 is all the current supplied to the load 31 in the target space connected to the branch wiring SW branched from all the fourth wirings W4, the current supplied from the fifth wiring W5 to the control device 11, and the current supplied from the seventh wiring W7 to the electric vehicle power supply device 21. Therefore, the first current sensor CS1 transmits, as power data, at least any one of the current in the second wiring W2, the current in the third wiring W3, or the total current supplied to the load 31 in the target space connected to the branch wiring SW branched from the fourth wiring W4 to the target space power measurement unit 113 of the control device 11 via the first communication cable CC1.

[0039] Furthermore, a first voltage sensor VS1 may be connected to any of the first to eighth wires W, such as the second wire W2, the third wire W3, or the fourth wire W4. However, the first voltage sensor VS1 is not an essential component of the electric vehicle power supply control system 1. Alternatively, the first voltage sensor VS1 may be built into the control device 11 and connected to the fifth wire W5. When the first voltage sensor VS1 is connected to the second wire W2, the third wire W3, or the fourth wire W4, the electric vehicle power supply control system 1 further includes a second communication cable CC2. One end of the second communication cable CC2 is connected to the target space power measurement unit 113 of the control device 11, and the other end is connected to the voltage data transmission unit of the first voltage sensor VS1, so that voltage data can be transmitted from the first voltage sensor VS1 to the target space power measurement unit 113 of the control device 11. The first voltage sensor VS1 generates voltage data of the measured voltage and transmits it from the voltage data transmitter to the target space power measuring unit 113 of the control device 11 via the second communication cable CC2. Note that although the voltage sensor VS is also shown in the figure simply as being connected to the wiring of the measurement target, such as the fourth wiring group W4G, it may be connected to a wiring indicating a reference power (which may be 0 V) in addition to the wiring of the measurement target, or may be connected to these two wires when the measurement target is paired with a positive wiring and a negative wiring.

[0040] A first voltage sensor VS1 is connected to any one of the first to eighth wirings W, such as the second wiring W2, the third wiring W3, the fourth wiring W4, or the fifth wiring W5, and when the target space power measurement unit 113 of the control device 11 receives voltage data from the voltage data transmission unit of the first voltage sensor VS1, the control device 11 can recognize the voltage of the power flowing through the second wiring W2, the third wiring W3, or the fourth wiring W4.

[0041] The eighth wiring W8 has one end connected to the electric vehicle power supply unit 212 of the electric vehicle power supply device 21 so that electric power can be passed through, and the other end connected to the supply power receiving unit 411 of the electric vehicle side power storage system 41 of the electric vehicle.

[0042] FIG. 3 is a diagram showing an example of a distribution board DB incorporating the control device 11 as a modification of the first embodiment. That is, the control device 11 may be sized to be incorporated in the distribution board DB and may be incorporated in the distribution board DB. When the control device 11 is incorporated in the distribution board DB, the fifth wiring W5 may also be incorporated in the distribution board DB, and a part of the first communication cable CC4 may also be incorporated in the distribution board DB. Since other points are the same as those described in the first embodiment above, they are omitted.

[0043] FIG. 4 is a diagram showing an example of the electric wire EL in the wiring W according to the present embodiment. The voltage of the 0V wire 0EL is about 0V. The voltage of the +100V wire +EL is about +100V. The voltage of the -100V wire -EL is about -100V.

[0044] The first wiring W1 to the eighth wiring W8 can be composed of any of two wires of the 0V wire 0EL and the +100V wire +EL, two wires of the 0V wire 0EL and the -100V wire -EL, two wires of the +100V wire +EL and the -100V wire -EL, and three wires of the 0V wire 0EL, the +100V wire +EL, and the -100V wire -EL. Note that not all the wirings W need to have the same configuration of the electric wire EL. The upstream wiring W such as the first wiring W1 has the above three-wire configuration, and the seventh wiring W7 and the eighth wiring W8 may have any of the above two-wire configurations (particularly, the two-wire configuration of the +100V wire +EL and the -100V wire -EL). Also, a separate ground wire may be provided. For example, it may be drawn from the first wiring W1, or a ground rod (earthing rod) may be provided on the side of the electric vehicle power supply device 21 to wire the ground wire. In particular, the eighth wiring W8 may include a ground wire, a communication wire, and a connection confirmation wire in addition to the power supply wire, and may be configured to transmit and receive information such as the maximum supply power information by the communication wire. <Configuration of Control Device 11>

[0045] FIG. 5 is a diagram showing an example of the electric vehicle power supply control system 1 according to the present embodiment. As described above, the electric vehicle power supply control system 1 includes the control device 11, the electric vehicle power supply device 21, and the electric vehicle side power storage system 41.

[0046] As described above, the control device 11 includes a power supply power receiving unit 111, an allowable power storage unit 112, a target space power measurement unit 113, a power difference setting unit 114, a supply power control unit 115, and an information processing unit 119.

[0047] The power supply power receiving unit 111 receives the power supply power necessary for the operation of the control device 11. The power supply power may be received, for example, from any of the wirings W (any of the third wiring W3 to the seventh wiring W7 or a dedicated wiring W (not shown)) under the leakage circuit breaker ELB, or from a dedicated battery (not shown), a dedicated power generation device (such as sunlight), a power generation device described later, etc., and is not limited thereto.

[0048] The allowable power storage unit 112 stores allowable power information indicating the allowable power, which is the upper limit of the consumable power, in the target space that receives commercial power from the commercial power system.

[0049] Power is Power = Voltage × Current and is calculated. The unit of power is W, the unit of voltage is V, and the unit of current is A.

[0050] Since the commercial power received by each target space is generally a fixed value of about 100V or about 200V, the allowable power storage unit 112 may store only the value (A) of the allowable current for the allowable power. However, the allowable power storage unit 112 may store both the value (V) of the voltage of the commercial power and the value (A) of the allowable current, or may store the value (W) of the allowable power.

[0051] The allowable power storage unit 112 may store allowable power information in advance, or may store the allowable power information indicated by a physical switch for setting the allowable power provided in the control device 11, or may store the allowable power information by receiving the allowable power information via the information processing unit 119 described later. The allowable power information stored in the allowable power storage unit 112 may be, for example, 30 (A) as the breaker capacity, or may be a value lower than the breaker capacity by a predetermined value. Further, when the allowable power storage unit 112 stores both the value (V) of the commercial power voltage and the value (A) of the allowable current, for example, the value of the commercial power may be 100 (V) or 200 (V), and the allowable current value may be 30 (A) or the like.

[0052] The information processing unit 119 is a functional unit that manages information processing such as reception or transmission of predetermined information in the control device 11, reading of information from a predetermined storage unit, and storage in a predetermined storage unit. The information processing unit 119 receives an input of allowable power information to be stored in the allowable power storage unit 112. The information processing unit 119 receives an input of allowable power information to be stored in the allowable power storage unit 112 regardless of whether the allowable power is stored in the allowable power storage unit 112 in advance or not. When new allowable power information is input to the information processing unit 119 while the allowable power storage unit 112 stores the allowable power information, the allowable power storage unit 112 deletes the stored allowable power information or associates storage time information (for example, information on the stored date or date and time information) so that the latest allowable power information can be grasped, and stores the new allowable power information received by the information processing unit 119. When the allowable power storage unit 112 does not store the allowable power information, when the allowable power information is input, the allowable power storage unit 112 stores the allowable power information received by the information processing unit 119.

[0053] The information processing unit 119 may receive the allowable power information via an input / output port. Examples of the input / output port include RS-232, RS485, RS422, USB (Universal Serial Bus), i.LINK, FireWire, PS / 2 connector, VGA terminal, DVI port, and the like.

[0054] When the input / output port of the information processing unit 119 and a terminal device (for example, a mobile terminal device such as a personal computer or a smartphone) or a server is connected by a communication cable, the personal computer or the server may transmit the allowable power information to the information processing unit 119.

[0055] Further, the information processing unit 119 may receive the allowable power via the wireless receiving device included in the control device 11. In this case, the allowable power information may be transmitted by wireless communication from a personal computer, server, smartphone, or mobile phone via a predetermined wireless network. The wireless network may be a short-range communication interface such as Bluetooth (registered trademark) and BLE (Bluetooth Low Energy) or Wi-Fi. As a more specific example, a predetermined application (for example, it may be a dedicated application or a browser application for using a web service) may be launched on a terminal such as a smartphone, and the allowable power input by an input operation on the application may be transmitted as the allowable power information. Transmissions of various information from the terminal may be transmitted by directly communicating from the terminal with the control device 11 or the electric vehicle power supply device 21 via a network, and / or may be once transmitted from the terminal to a server via a network and then transmitted from the server to the control device 11 or the electric vehicle power supply device 21 via a network.

[0056] The allowable power storage unit 112 stores allowable power information in advance. When the allowable power information stored in the allowable power storage unit 112 cannot be changed, the control device 11 does not necessarily have a function of receiving the allowable power information in the information processing unit 119.

[0057] The target space power measurement unit 113 measures the target space power consumption supplied to the target space load 31, which is a load that consumes power in the target space. The target space power measurement unit 113 receives power data transmitted by the first current sensor CS1 as the target space power consumption. Alternatively, or in addition, the target space power measurement unit 113 receives power data (voltage data) transmitted by the first voltage sensor VS1 as the target space power consumption. Note that the above-mentioned "receiving power data as the target space power consumption" may include, for example, calculating power based on the power data (current data) transmitted by the first current sensor CS1 and reference voltage data, or based on the voltage data transmitted by the first voltage sensor VS1 and reference current data, or based on the power data (current data) transmitted by the first current sensor CS1 and the voltage data transmitted by the first voltage sensor VS1, and determining the power as the target space power consumption. In addition, when each sensor is connected to the second wiring W2 or the third wiring W3, the power consumption of the control device 11 and the power consumption of the electric vehicle power supply device 21 may also be included as the target space power consumption.

[0058] The power difference setting unit 114 sets the power difference, which is the difference between the above-mentioned allowable power and the power consumption of the target space, as power difference information.

[0059] The supply power control unit 115 transmits at least one of the above-mentioned target space power consumption information indicating the target space power consumption and the maximum supply power information indicating the maximum supply power to the electric vehicle power supply device.

[0060] Here, the information transmitted by supply power control unit 115 may differ depending on whether control unit 11 has a function for calculating the maximum supply power. That is, first, if control unit 11 has a function for calculating the maximum supply power, supply power control unit 115 generates maximum supply power information indicating the maximum supply power that can be supplied by electric vehicle power supply device 21, for example, based on the power difference described above. Note that the maximum supply power information indicating the maximum supply power may be, for example, information indicating a duty ratio corresponding to the maximum supply power when the supply power described below is adjusted by setting a duty ratio.

[0061] The power supply control unit 115 may set all of the power values of the power difference as the maximum supply power.

[0062] Alternatively, when the power supply control unit 115 sets all of the power values of the power difference as the maximum supply power, if the electric vehicle power supply device 21 supplies the maximum supply power to the electric vehicle and the target space power consumption suddenly increases, the target space power consumption may exceed the allowable power. Therefore, a margin power difference obtained by further subtracting a margin power from the power difference may be set as the maximum supply power.

[0063] Alternatively, the power supply control unit 115 may set the power value of the maximum supply power by multiplying the power value of the power difference by a coefficient that is 0 or more and 1 or less.

[0064] In addition, when the power supply control unit 115 sets the power obtained by multiplying the power value of the power difference by a coefficient that is 0 or more and 1 or less as the maximum supply power, the power supply control unit 115 may change the coefficient according to the ratio of the power value of the power difference to the power value of the allowable power. That is, when the power value of the power difference is large with respect to the power value of the allowable power, the power supply control unit 115 may increase the coefficient, and when the power value of the power difference is small with respect to the power value of the allowable power, the power supply control unit 115 may decrease the coefficient. In this way, when the power value of the power difference is large with respect to the power value of the allowable power, by increasing the coefficient, the maximum supply power that can be supplied by the electric vehicle power supply device 21 can be increased, and the supply power supplied to the electric vehicle side power storage system 41 provided in the electric vehicle can be set large. Also, when the power value of the power difference is small with respect to the power value of the allowable power, by decreasing the coefficient, the maximum supply power can be decreased, and the possibility that power is not supplied from the main breaker MB to the load 31 in the target space due to the target space power consumption exceeding the allowable power can be reduced.

[0065] When the power supply control unit 115 changes the coefficient according to the power value of the power difference with respect to the power value of the allowable power, for example, as shown in Table 1, the coefficient may be changed. TIFF2025112186000002.tif Table 1 of 30108

[0066] Therefore, by setting the maximum supply power such that the maximum supply power is equal to or less than the power difference (i.e., less than or equal to the power difference), the supply power control unit 115 can set the maximum supply power so as not to exceed the allowable power.

[0067] Note that the margin power difference obtained by subtracting the power multiplied by the coefficient or the margin power is also referred to as "calculated power".

[0068] In addition, the above coefficients and margin power may be arbitrarily set by a user (such as a user or a constructor). More specifically, the user may start a predetermined application (for example, it may be a dedicated application or a browser application for using a web service) on a terminal such as a smartphone, and transmit the coefficients or margin power input by an input operation on the application to the control device 11 or the electric vehicle power supply device 21 as coefficient information or margin power information via a network. Further, the coefficients or margin power may be repeatedly set according to a predetermined schedule. That is, the coefficients or margin power may be set by the user for each predetermined time unit of a day (for example, 0.5-hour unit, 1-hour unit, etc.) or for each period unit (for example, units preset in the system such as day of the week unit, week unit, month unit, morning / noon / evening, etc.). After the user's setting, the coefficients or margin power as set may be configured to be set in the corresponding time zone or period zone (day of the week, week, month, etc.). Alternatively, a configuration may be provided in which two or more settings with different coefficient or margin power settings are prepared in advance on the system and can be selected according to user operations (for example, select from a first setting with a coefficient of 1 or a margin power of 0 in the night time zone and a second setting with a coefficient less than 1 or a margin power greater than 0 in other time zones). Furthermore, instead of the coefficients and margin power, the user may be able to directly set the maximum supply power. As described above, the transmission of various information from the terminal may be transmitted by directly communicating from the terminal with the control device 11 or the electric vehicle power supply device 21 via a network, and / or may be transmitted from the terminal to the server via a network once and then transmitted from the server to the control device 11 or the electric vehicle power supply device 21 via a network.

[0069] Next, when the control device 11 does not have a function of calculating the maximum supply power and the electric vehicle power supply device 21 has a function of calculating the maximum supply power, the supply power control unit 115 transmits, for example, target space power consumption information used for calculating the maximum supply power to the electric vehicle power supply device 21 via, for example, the fourth communication cable CC4. On the other hand, the electric vehicle power supply device 21 may include, as a functional unit, a part of the functions of the above-described supply power control unit 115 (for example, the supply power control unit 213 in FIG. 6), and may set the maximum supply power in the same manner as the supply power control unit 115 based on the target space power consumption information received from the control device 11. At this time, the allowable power storage unit 112 and the power difference setting unit 114 may be provided in the electric vehicle power supply device 21, or the allowable power information and the power difference information may be transmitted to the electric vehicle power supply device 21.

[0070] Therefore, by setting the maximum supply power such that the maximum supply power of the electric vehicle power supply device 21 is equal to or less than the power difference (that is, not exceeding the power difference), the electric vehicle power supply device 21 can set the maximum supply power so as not to exceed the allowable power.

[0071] <Configuration of Electric Vehicle Power Supply Device 21> As shown in FIG. 5, the electric vehicle power supply device 21 includes a power supply power receiving unit 211 that receives power supply power and an electric vehicle power supply unit 212 that supplies supply power to the electric vehicle side power storage system 41. It is desirable that the electric vehicle power supply device 21 complies with a predetermined standard such as SAE J1772 and IEC 61851 / 62196.

[0072] The electric vehicle power supply unit 212 supplies supply power (which can also be said to be charging power because it is mainly charging power) to the on-vehicle side power storage system 41 of the electric vehicle as described above. The supply power is controlled in the on-vehicle side power storage system 41 based on the maximum supply power information for the received power. However, not limited to this, the supply power may be controlled based on the maximum supply power information and the electric vehicle related information (for example, information on the mounted storage battery (current stored amount, temperature, voltage, etc.) and information on the state of the electric vehicle (temperature, operating devices, etc.)) in the electric vehicle power supply unit 212, or may be controlled based on the supply power instruction information received from the on-vehicle side power storage system 41. The supply power instruction information can be, for example, information indicating the supply power during a predetermined period. More specifically, for example, in a configuration where power supply with a predetermined duty ratio is performed from the electric vehicle power supply device 21, the supply power instruction information can be instruction information specifying the duty ratio.

[0073] The information processing unit 219 is a functional unit that manages information processing such as reception or transmission of predetermined information in the electric vehicle power supply device 21, reading of information from a predetermined storage unit, and storage in a predetermined storage unit. For example, it causes the maximum supply power information received from the control device 11 to be transmitted via a communication line such as the eighth wiring W8.

[0074] <Configuration of the on-vehicle side power storage system 41> The electric vehicle power supply control system 1 includes an on-vehicle side power storage system 41 provided in the electric vehicle. The on-vehicle side power storage system 41 includes a supply power receiving unit 411 that receives supply power from the electric vehicle power supply unit 212 of the electric vehicle power supply device 21, a storage battery 412 in which the received power is stored, a received power control unit 413 that controls the received power, and an information processing unit 419. In this way, the received power received from the electric vehicle power supply unit 212 of the electric vehicle power supply device 21 can be stored in the storage battery 412.

[0075] The on-vehicle side power storage system 41 is generally provided inside the vehicle body of the electric vehicle. However, the on-vehicle side power storage system 41 may be provided outside the vehicle body of the electric vehicle.

[0076] The power supply receiving unit 411 receives the supplied power from the vehicle power supply unit 212 of the vehicle power supply device 21. When the supplied power is alternating current (AC), the power supply receiving unit 411 preferably has an AC / DC conversion function. Further, the power supply receiving unit 411 controls the received supplied power to a predetermined received power based on the control of the received power control unit 413 described later.

[0077] As shown in FIG. 1, one end of the eighth wiring W8 is connected to the vehicle power supply unit 212 of the vehicle power supply device 21 so that the supplied power can be energized, and the other end is connected to the power supply receiving unit 411 of the vehicle-side power storage system 41.

[0078] The storage battery 412 may be any existing storage battery as long as it can store the received power. As an example, the power supply receiving unit 411 and the storage battery 412 may be connected by wiring (not shown), or a known wireless charging method may be used.

[0079] When the power is not stored in the storage battery 412, or when the power stored in the storage battery 412 is not sufficient to operate the power storage system 41, for example, the vehicle-side power storage system 41 consumes at least a part of the received power received by the power supply receiving unit 411 and operates to charge the storage battery 412. However, when the power stored in the storage battery 412 is sufficient to operate the vehicle-side power storage system 41, the vehicle-side power storage system 41 receives the power necessary to operate from the power charged in the storage battery 412.

[0080] The power reception control unit 413 controls so as to obtain an optimal power reception power (charging power) with a power (current) equal to or less than the maximum power supplyable power according to the maximum supply power information received from the vehicle power supply device 21 (for example, information indicating a duty ratio corresponding to the maximum supply power. When the control device 11 generates the maximum supply power information, this includes the vehicle power supply device 21 receiving the information and transmitting it from the vehicle power supply device 21) and vehicle-related information (for example, information on the mounted storage battery (current stored power, temperature, voltage, etc.) and information on the state of the vehicle (temperature, operating devices, etc.)).

[0081] The information processing unit 419 is a functional unit that manages information processing such as reception or transmission of predetermined information in the vehicle-side power storage system 41, reading of information from a predetermined storage unit, and storage in a predetermined storage unit.

[0082] <Modification Example of Embodiment 1> FIG. 7 is a diagram showing a modification example of the first embodiment. For the vehicle power supply control system 1 of this modification example, only the parts different from the vehicle power supply control system 1 of the first embodiment will be described. In the modification example shown in FIG. 7, the breaker EVB for the vehicle power supply device 21 (for example, a leakage breaker) provided in the distribution board DB in the first embodiment is connected to the power meter EM.

[0083] That is, one end of the sixth wiring W6 is connected to the power meter EM so that power can be energized, and the other end is connected to the power reception part of the breaker EVB for the vehicle power supply device 21.

[0084] One end of the seventh wiring W7 is connected to the power supply part of the breaker EVB for the vehicle power supply device 21 so that power can be energized, and the other end is connected to the power supply power reception part 211 of the vehicle power supply device 21.

[0085] With such a configuration, it becomes possible to provide the breaker EVB only through the operation on the power meter EM outside the target space, without going through the operation of separately providing the breaker EVB in the distribution board DM inside the target space.

[0086] Also, particularly when each sensor is provided in the second wiring W2 or the third wiring W3, unlike the first embodiment, the power consumption of the electric vehicle power supply device 21 is not included in the power consumption of the target space, and the control device 11 cannot sense the power consumption of the electric vehicle power supply device 21. Therefore, in the supply power control unit 115, for example, the power consumption information of the electric vehicle power supply device 21 is acquired via the fourth communication cable CC4, and further, the power obtained by subtracting the power consumption of the electric vehicle power supply device 21 from the power indicated by the power difference may be set as the maximum supply power. Regarding this, even when setting the maximum supply power in the electric vehicle power supply device 21 as illustrated in FIG. 6, the same processing can be performed in the supply power control unit 213. That is, in the electric vehicle power supply device 21, the power consumption information of the target space is received via the fourth communication cable CC4, and the power consumption information of the electric vehicle power supply device 21 is acquired within the electric vehicle power supply device 21, so that the same processing can be performed in the supply power control unit 213 based on both power consumption information.

[0087] <Embodiment 2> The electric vehicle power supply control system 1 of the second embodiment is a different embodiment from the electric vehicle power supply control system 1 of the first embodiment. Regarding the electric vehicle power supply control system 1 of the second embodiment, only the parts different from the electric vehicle power supply control system 1 of the first embodiment will be described.

[0088] FIG. 8 is a diagram showing an example of the electric vehicle power supply control system 1 including the power generation device 51 according to the second embodiment. The electric vehicle power supply control system 1 of the second embodiment is different from the electric vehicle power supply control system 1 of the first embodiment in that it further includes the power generation device 51.

[0089] FIG. 10 is a diagram showing an example of the electric vehicle power supply control system 1 according to the second embodiment. The electric vehicle power supply control system 1 of the second embodiment is different from the electric vehicle power supply control system 1 of the first embodiment in that the control device 11 includes a generated power measurement unit 116 that measures the generated power of the power generation device 51 instead of the target space power measurement unit 113.

[0090] Further, the electric vehicle power supply control system 1 of the second embodiment is also different from the electric vehicle power supply control system 1 of the first embodiment in that it further includes a second current sensor CS2.

[0091] The power generation device 51 is a power generation device that generates power using at least one of sunlight, wind power, hydraulic power, geothermal heat, solar heat, heat existing in nature such as heat in the atmosphere, or biomass (organic matter derived from animals and plants) (including so-called renewable energy power generation devices or natural energy power generation devices). The power generation device 51 is a power generation device installed in the target space. For example, when it is a solar power generation device or a wind power generation device, the power generation device 51 may be installed on the roof R of the house HU or in the garden (not shown).

[0092] Also, when the power generation device 51 outputs DC power, a DC / AC converter 61 may be provided. The DC / AC converter 61 is a device that converts the DC power generated by the power generation device 51 into AC power. However, when the power generation device 51 outputs AC power, the DC / AC converter 61 does not need to be provided.

[0093] One end of the ninth wiring W9 is connected to the power generation device 51 so that power can be energized, and the other end is connected to the power receiving unit of the DC / AC converter 61. As described above, when the power generation device 51 outputs AC power, the DC / AC converter 61 does not need to be provided, and the other end of the ninth wiring W9 may be connected to the distribution board DB.

[0094] The tenth wiring W10 has one end connected to the output section of the DC / AC converter 61 and the other end connected to the power receiving section of the main breaker MB built in the distribution board DB so that power can be energized.

[0095] FIG. 9 is a diagram showing an example of the distribution board DB according to the second embodiment. The electric vehicle power supply control system 1 of the second embodiment is different from the electric vehicle power supply control system 1 of the first embodiment in that the power receiving section of the main breaker MB is connected not only to the first wiring W1 through which commercial power flows but also to the tenth wiring W10 through which generated power flows. If the power receiving section of the main breaker MB is connected not only to the first wiring W1 through which commercial power flows but also to the tenth wiring W10 through which generated power flows, the power receiving section of the main breaker MB can receive not only commercial power but also generated power (also referred to as "target space generated power"). When supplying the received power to the in-target space load 31 or the electric vehicle power supply device 21, the configuration is such that the target space generated power is prioritized over commercial power. This is generally because when the in-target space power consumption is equal to or less than the target space generated power, there is no need to take in power from commercial power and it is possible to cover it only with the target space generated power, and when the in-target space power consumption is greater than the target space generated power, only the difference is taken in from commercial power. However, it is not limited to this. For example, when it is detected by the second current sensor CS2 or the second voltage sensor CV2 that the target space generated power is being output, the connection destination may be switched by a switching device or the like so that the target space generated power is preferentially supplied.

[0096] The second current sensor CS2 measures the current in the ninth wiring W9 or the tenth wiring W10 and generates second power data (current data) based on the measured current.

[0097] One end of the third communication cable CC3 is connected to the second current sensor CS2 and the other end is connected to the control device 11 so that the second power data can be transmitted from the second current sensor CS2 to the control device 11.

[0098] Note that, similar to Embodiment 1, instead of or in addition to the second current sensor CS2 and the third communication cable CC3, a second voltage sensor VS2 may be provided to measure the voltage of the ninth wiring W9 or the tenth wiring W10, and generate second power data (voltage data) based on the measured voltage. Also, in FIG. 8, a configuration in which a sensor is provided outside the distribution board DB is illustrated, but the present invention is not limited to this, and it may be built in the distribution board DB and provided on the target wiring.

[0099] Here, similar to Embodiment 1, the information transmitted by the power supply control unit 115 may differ depending on whether the control device 11 has a function of calculating the maximum supply power. That is, first, when the control device 11 has a function of calculating the maximum supply power, the power supply control unit 115 generates, for example, maximum supply power information indicating the maximum supply power that can be supplied by the electric vehicle power supply device 21 based on the above-described target space generated power.

[0100] The power supply control unit 115 compares the allowable power with the target space generated power, and when it is determined that the target space generated power is less than or equal to the allowable power value, all of the power values of the target space generated power may be set as the maximum supply power.

[0101] Note that, regarding the allowable power in the configuration of the present invention, the allowable power that can be consumed in the target space is the same as in Embodiment 1 because it is derived from the allowable current (allowable power) of the main breaker MB. Also, even when the target space generated power is less than or equal to the allowable power value, if the power supply control unit 115 sets all of the power values of the target space generated power as the maximum supply power, and the electric vehicle power supply device 21 supplies the maximum supply power to the electric vehicle, when the target space power consumption increases, the sum of the supply power by the electric vehicle power supply device 21 (in this case, the target space generated power) and the target space power consumption may exceed the allowable power. Therefore, the margin target space generated power obtained by subtracting a margin power from the target space generated power may be set as the maximum supply power.

[0102] Also, similar to Embodiment 1, the supply power control unit 115 may be set as the power value of the maximum supply power by multiplying the power value of the target space generated power by a coefficient that is 0 or more and 1 or less. Details may be the same as those in the case of multiplying a coefficient by the power difference in Embodiment 1 (that is, reading "power difference" in Embodiment 1 as "target space generated power"), so it will be omitted.

[0103] Therefore, by setting the maximum supply power so that the maximum supply power is equal to or less than the target space generated power (that is, less than or equal to the target space generated power), the supply power control unit 115 can set the maximum supply power so as not to exceed the allowable power.

[0104] Also, similar to Embodiment 1, the above-described coefficient and margin power may be arbitrarily set by the user (such as the user or installer). In Embodiment 2, instead of or in addition to the configuration of Embodiment 1, for example, the user may be able to select a mode in which the coefficient is set relatively higher or the margin power is set relatively lower in the daytime zone including daytime than in other time zones. Thereby, for example, in a power generation device with a large power generation amount during the day such as solar power generation, it becomes possible to use a large amount of the generated power for charging, and it becomes possible to reduce the purchased power from the power company. Alternatively, the user may be able to select a mode in which the coefficient is set relatively higher or the margin power is set relatively lower in the nighttime zone including night than in other time zones. Thereby, for example, the surplus can be sold during the day, and it becomes possible to mainly charge during the nighttime zone where the electricity rate is inexpensive.

[0105] Next, when the control device 11 does not have a function of calculating the maximum supply power and the electric vehicle power supply device 21 has a function of calculating the maximum supply power, the supply power control unit 115 transmits, for example, target space power generation power information used for calculating the maximum supply power to the electric vehicle power supply device 21. On the other hand, in the electric vehicle power supply device 21, similar to the first embodiment, a part of the functions of the above-described supply power control unit 115 may be provided as a functional unit (supply power control unit 213), and the maximum supply power may be set in the same manner as the supply power control unit 115 based on the target space power generation power information received from the control device 11.

[0106] <Modification Example of Embodiment 2> FIG. 11 is a diagram showing a modification example of the second embodiment. Only the parts different from the electric vehicle power supply control system 1 of the second embodiment will be described for the electric vehicle power supply control system 1 of this modification example. In this modification example shown in FIG. 11, a breaker EVB for the electric vehicle power supply device 21 provided in the distribution board DB in the second embodiment is connected to the power meter EM.

[0107] That is, one end of the sixth wiring W6 is connected to the power meter EM so that power can be energized, and the other end is connected to the power receiving part of the breaker EVB for the electric vehicle power supply device 21.

[0108] One end of the seventh wiring W7 is connected to the power supply part of the breaker EVB for the electric vehicle power supply device 21 so that power can be energized, and the other end is connected to the power supply power receiving part 211 of the electric vehicle power supply device 21.

[0109] With such a configuration, it becomes possible to provide the breaker EVB only by working on the power meter EM outside the target space without going through the work of separately providing the breaker EVB in the distribution board DB inside the target space.

[0110] <Embodiment 3> The electric vehicle power supply control system 1 of Embodiment 3 can be said to be a configuration that combines the electric vehicle power supply control system 1 of Embodiment 1 and the electric vehicle power supply control system 1 of Embodiment 2. Only the parts different from the electric vehicle power supply control systems 1 of Embodiments 1 and 2 will be described.

[0111] FIG. 12 is a diagram showing an example of the electric vehicle power supply control system 1 including the power generation device 51 according to the present Embodiment 3. The electric vehicle power supply control system 1 of Embodiment 3 has the first current sensor CS1 in the same manner as the electric vehicle power supply control system 1 of Embodiment 1, and is different from the two in that it has the second current sensor CS2 in the same manner as the electric vehicle power supply control system 1 of Embodiment 2. Note that the configuration of the distribution board DB may be the same as that of Embodiment 2. Also, as in Embodiment 1, the control device 11 may be provided inside the distribution board.

[0112] FIG. 13 is a diagram showing an example of the electric vehicle power supply control system 1 according to the present Embodiment 3. The electric vehicle power supply control system 1 of Embodiment 3 is different from the electric vehicle power supply control systems 1 of Embodiments 1 and 2 in that the control device 11 includes a power generation power measurement unit 116 that measures the target space power generation power of the power generation device 51 in addition to having the target space power measurement unit 113 of Embodiment 1.

[0113] Here, in Embodiment 3, as described above, since the target space power measurement unit 113 and the power generation power measurement unit 116 are provided, the supply power control unit 115 of Embodiment 3 can perform control considering both the target space power consumption and the target space power generation power in addition to or instead of the processing of the supply power control unit 115 in Embodiments 1 and 2.

[0114] Here, as in the first and second embodiments, the information transmitted by the power supply control unit 115 may differ depending on whether the control device 11 has a function of calculating the maximum supply power. That is, first, when the control device 11 has a function of calculating the maximum supply power, the power supply control unit 115 generates, for example, maximum supply power information indicating the maximum supply power that can be supplied by the electric vehicle power supply device 21 based on the above-described target space power consumption and target space power generation.

[0115] More specifically, in the configuration of the second embodiment, it is assumed that there is a scenario where the target space power generation is not necessarily large and there is no impact even if all of the target space power generation is set as the maximum supply power, or even if not, it is assumed to cope with the situation where the sum of the supply power by the electric vehicle power supply device 21 (in this case, the target space power generation) and the target space power consumption exceeds the allowable power due to the margin power or coefficient. However, the power supply control unit 115 compares, for example, the power difference, which is the difference between the allowable power and the target space power consumption, with the target space power generation. When the target space power generation is smaller than the power difference, the target space power generation may be set as the maximum supply power. And the power supply control unit 115 may set the power difference as the maximum supply power, for example, when the target space power generation is larger than the power difference. By setting the maximum supply power in this way, it is possible to operate without the sum of the supply power by the electric vehicle power supply device 21 (in this case, the target space power generation) and the target space power consumption exceeding the allowable power.

[0116] In the third embodiment as well, it is also possible to adopt the above-described margin power and coefficient in setting the maximum supply power.

[0117] Also, as in the first and second embodiments, the above-described coefficient and margin power may be arbitrarily set by the user (such as the user or installer).

[0118] Next, when the control device 11 does not have a function of calculating the maximum supply power and the electric vehicle power supply device 21 has a function of calculating the maximum supply power, the supply power control unit 115 transmits, for example, the target space power consumption information and the target space power generation power information used for calculating the maximum supply power to the electric vehicle power supply device 21. On the other hand, in the electric vehicle power supply device 21, similar to the first and second embodiments, a part of the functions of the above-described supply power control unit 115 may be provided as a functional unit (supply power control unit 213), and the maximum supply power may be set in the same manner as the supply power control unit 115 based on the target space power consumption information and the target space power generation power information received from the control device 11. At that time, the allowable power storage unit 112 and the power difference setting unit 114 may be provided in the electric vehicle power supply device 21, or the allowable power information and the power difference information may be transmitted to the electric vehicle power supply device 21.

[0119] <Modification Example of Embodiment 3> FIG. 14 is a diagram showing a modification example of the third embodiment. Only the parts different from the electric vehicle power supply control system 1 of the third embodiment will be described for the electric vehicle power supply control system 1 of this modification example. In this modification example shown in FIG. 14, the breaker EVB for the electric vehicle power supply device 21 provided in the distribution board DB in the third embodiment is connected to the power meter EM.

[0120] That is, one end of the sixth wiring W6 is connected to the power meter EM so that power can be energized, and the other end is connected to the power receiving portion of the breaker EVB for the electric vehicle power supply device 21.

[0121] One end of the seventh wiring W7 is connected to the power supply portion of the breaker EVB for the electric vehicle power supply device 21 so that power can be energized, and the other end is connected to the power supply power receiving portion 211 of the electric vehicle power supply device 21.

[0122] With such a configuration, it is possible to provide the breaker EVB only by working on the power meter EM outside the target space without going through the work of separately providing the breaker EVB in the distribution board DB inside the target space.

[0123] Also, particularly when the first current sensor CS1 and the first voltage sensor CV1 are provided on the second wiring W2 and the third wiring W3 (not shown), unlike the third embodiment, the power consumption of the electric vehicle power supply device 21 is not included in the target space power consumption, and the control device 11 cannot sense the power consumption of the electric vehicle power supply device 21. Therefore, in the supply power control unit 115, for example, the power consumption information of the electric vehicle power supply device 21 is acquired via the fourth communication cable CC4, and further, the power obtained by subtracting the power consumption of the electric vehicle power supply device 21 from the power indicated by the power difference is set as the power difference information used by the supply power control unit 115. Regarding this, the same processing can be performed in the supply power control unit 213 when setting the maximum supply power in the electric vehicle power supply device 21. That is, in the electric vehicle power supply device 21, the target space power consumption information is received via the fourth communication cable CC4, and the power consumption information of the electric vehicle power supply device 21 is acquired within the electric vehicle power supply device 21, so that the same processing can be performed in the supply power control unit 213 based on both power consumption information.

[0124] <Other Modification Example 1> In the first to third embodiments, examples are shown in which the control device 11, at least one of the first current sensor CS1, the first voltage sensor CV1, the second current sensor CS2, the second voltage sensor CV2, and the electric vehicle power supply device 21, or the electric vehicle power supply device 21, the electric vehicle side power storage system 41, the power meter EM, and the control device 11 or the electric vehicle power supply device 21 perform transmission and reception of various information via wiring or communication cables to each other. Instead of this, or in addition, a wireless communication unit (not shown) may be provided to perform transmission and reception of various information via a network.

[0125] The network communicates according to communication rules such as TCP / IP (Transmission Control Protocol / Internet Protocol). Also, the network NW may be a virtual circuit. The virtual circuit may be, for example, a VPN (Virtual Private Network), an Internet VPN (Virtual Private Network), an Entry VPN (Virtual Private Network), an IP (Internet Protocol)-VPN (Virtual Private Network), a wide area Ethernet, or the like.

[0126] When transmitting and receiving various information via the network, it may be transmitted to the server once via the network and then the server may transmit various information via the network.

[0127] Also, the network may be a wireless network. The wireless network WNW mentioned here may be a short-range communication interface exemplified by Bluetooth (registered trademark) and BLE (Bluetooth Low Energy), Wi-Fi, etc. The control device 11 and the above-mentioned first current sensor CS1, etc. may directly transmit and receive various information via the wireless network.

[0128] <Another Modification Example 2> In Embodiments 1 to 3, the control device 11, the first current sensor CS1, the first voltage sensor CV1, etc. are provided for the distribution board DB. However, instead of or in addition to this, the power meter EM may have at least some of the functions of the control device 11 and various sensors. That is, when the power meter EM is a so-called smart meter, the power meter EM itself may acquire the target space power consumption information. At that time, for example, (1) instead of various sensors, the power meter EM may be made capable of transmitting the target space power consumption information to the control device 11, or (2) instead of the control device 11 and various sensors, the power meter EM may be made capable of directly transmitting the target space power consumption information to the electric vehicle power supply device 21 (in this case, the maximum supply power is set by the electric vehicle power supply device 21), or (3) instead of the control device 11 and various sensors, the power meter EM may set the maximum supply power from the target space power consumption information and be made capable of transmitting the maximum supply power information to the electric vehicle power supply device 21. Furthermore, when the power generation device 51 is provided, the target space power generation power information may be acquired by the power meter EM, and the maximum supply power may be set as in Embodiment 3.

[0129] <Other Modification Example 3> Having devices not explicitly shown in Embodiments 1 to 3 does not prevent it. For example, a lightning arrester (SPD) may be provided for the electric vehicle power supply device 21. Or, in Embodiment 2 or 3, a functional distribution board (for example, a device that switches the connection of the distribution board to the power generation device 51 and a power storage device (not shown) when a power outage occurs) may be provided between the DC / AC converter 61 and the distribution board DB.

[0130] The above-described embodiments are merely examples for facilitating the understanding of the present invention, and are not for limiting the interpretation of the present invention. The present invention can be changed and improved without departing from its gist, and it goes without saying that equivalents of the present invention are included in the present invention.
