Therefore, the first current sensor CS converts 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 in-target space load 31 connected to the branch wiring SW branched from the fourth wiring W4 into power data and transmits it to the target space power measurement unit 113 of the control device 11 via the first communication cable CC1.

[0039] Furthermore, the first to eighth wirings such as the second wiring W2, the third wiring W3, or the fourth wiring W4 ​​​A first voltage sensor VS1 may be connected to any of the wirings W. However, the first voltage sensor VS1 is not an essential component of the electric vehicle power supply control system 1. Also , the first voltage sensor VS1 may be built into the control device 11 and connected to the fifth wiring W5. When the first voltage sensor VS1 is connected to the second wiring W2, the third wiring W3, or the fourth wiring W4, etc., 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 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, and the other end is connected to the voltage data transmission unit of the first voltage sensor VS1. The first voltage sensor VS1 generates voltage data of the measured voltage and transmits it from the voltage data transmission unit to the target space power measurement unit 113 of the control device 11 via the second communication cable CC2. Note that also in the case of the voltage sensor VS, only the configuration connected to the wiring to be measured, such as the fourth wiring group W4G in the figure, is schematically shown, but in addition to the wiring to be measured, it may be connected to a wiring indicating the reference power (which may be 0V), or when the measurement targets are paired as positive side wiring and negative side wiring, it may be configured to be connected to these two wires. The first voltage sensor VS1 generates voltage data of the measured voltage and transmits it from the voltage data transmission unit to the target space power measurement unit 113 of the control device 11 via the second communication cable CC2. When the target space power measurement unit 113 of the control device 11 receives the voltage data from the voltage data transmission unit of the first voltage sensor VS1, the control device 11 measures the current flowing through the second wiring W2, the third wiring W3, or the fourth wiring W4. Although only the configuration connected to the wiring to be measured, such as the fourth wiring group W4G in the figure, is schematically shown, in addition to the wiring to be measured, it may be connected to a wiring indicating the reference power (which may be 0V), or when the measurement targets are paired as positive side wiring and negative side wiring, it may be configured to be connected to these two wires. The first voltage sensor VS1 may be connected to any of the wirings W from the first to the eighth, such as the second wiring W2, the third wiring W3, the fourth wiring W4, and the fifth wiring W5. When the target space power measurement unit 113 of the control device 11 receives the voltage data from the voltage data transmission unit of the first voltage sensor VS1, the control device 11 measures the current flowing through the second wiring W2, the third wiring W3, or the fourth wiring W4.

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

It is possible to recognize the voltage of the power to be supplied.

[0041] One end of the eighth wiring W8 is connected to the power supply unit 212 of the electric vehicle power supply device 21 so that power can be energized, and the other end is connected to the power supply 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 is 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 is also incorporated in the distribution board DB, and a part of the first communication cable CC4 can also be incorporated in the distribution board DB. Other points are the same as those described in the first embodiment above, so they will be omitted.

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

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 The wiring W7 or the eighth wiring W8 may have any of the above two-wire configurations (in particular, the two-wire configuration of the +100V wire +EL and -100V wire -EL). Alternatively, an earth wire may be provided separately, for example, it may be drawn from the first wiring W1, or an earth rod (grounding rod) may be provided on the side of the electric vehicle power supply device 21 to wire the earth wire. In particular, the eighth wiring W8 includes an earth 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 maximum supply power information by the communication wire in particular. <Configuration of the 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 a control device 11, an electric vehicle power supply device 21, and an 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. Note that the power supply power may be received from any of the wirings W (either the third wiring W3 or the seventh wiring W7 of the wirings W under the leakage circuit breaker ELB) or a dedicated wiring W (not shown), or may be received from a dedicated battery (not shown), a dedicated power generation device (for example, sunlight), a power generation device described later, etc., and is not limited thereto.

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

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

[0050] The commercial power received by each target space is generally about 100V or about 200V and is a fixed value. Therefore, 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. (V), and the value (A) of the allowable current, or may store the value (W) of the allowable power. of the allowable power may be stored.

[0051] Allowable power information may be stored in the allowable power storage unit 112 in advance, or the allowable power information indicated by a physical switch for setting the allowable power provided in the control device 11 may be stored, or the allowable power information may be received via the information processing unit 119 described later and then stored. 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. Also, when the allowable power storage unit 112 stores both the value (V) of the voltage of the commercial power 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 value of the allowable current

[0052] may be 30 (A) or the like.

[0052] The information processing unit 119 is a functional unit that manages information processing such as receiving or transmitting predetermined information in the control device 11, reading information from a predetermined storage unit, and storing information in a predetermined storage unit. The information processing unit 119 accepts the input of allowable power information to be stored in the allowable power storage unit 112. The information processing unit 119 accepts the input of allowable power information to be stored in the allowable power storage unit 112, whether the allowable power is already stored in the allowable power storage unit 112 or not. In any case, the information processing unit 119 accepts the input of allowable power information to be stored in the allowable power storage unit 112. When new allowable power information is input to the information processing unit 119 while the allowable power storage unit 112 stores allowable power information, the stored allowable power information is erased, or the storage time information (for example, information on the stored date or time) is associated so that the latest allowable power information can be grasped, and the new allowable power information received by the information processing unit 119 is stored. When the allowable power storage unit 112 does not store allowable power information, it stores the allowable power information input thereto. The information processing unit 119 may accept allowable power information via an input / output port. The input / output port includes RS-232, RS485, RS 422, USB (Universal Serial Bus), i.LINK, FireWire, PS / 2 connector, VGA terminal, DVI port, etc. The information processing unit 119 may accept allowable power information via an input / output port. The input / output port includes RS-232, RS485, RS

[0053] The information processing unit 119 may accept allowable power information via an input / output port. The input / output port includes RS-232, RS485, RS 422, USB (Universal Serial Bus), i.LINK, FireWire, PS / 2 connector, VGA terminal, DVI port, etc. 422, USB (Universal Serial Bus), i.LINK, FireWire, PS / 2 connector, VGA terminal, DVI port, etc. The information processing unit 119 and a terminal device (for example, a personal computer (Personal

[0054] computer) or a mobile terminal device such as a smartphone), or a server (serv computer) or a mobile terminal device such as a smartphone), or a server (serv Connect the input / output ports of the (er) with a communication cable When this is the case, the personal computer or the server may transmit the allowable power information to the information processing unit 119.

[0055] Alternatively, the information processing unit 119 may receive the allowable power via the wireless receiving device of the control device 11. In this case, the personal computer (Personal com puter), server, smartphone, or mobile phone may wirelessly communicate (wireless communication) via a predetermined wireless network to transmit the allowable power information. 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 it may be a browser application for using web services) is launched on a terminal such as a smartphone and the allowable power input by an input operation on the application may be transmitted as 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 dual power supply device 21 via a network, or and / or transmitted from the terminal to the server via a network once and then from the server to the control device 11 or the electric vehicle dual power supply device 21 via the network .

[0056] ​​The allowable power storage unit 112 stores allowable power information in advance. If the allowable power information stored in the allowable power storage unit 112 cannot be changed, the control device 11 does not necessarily have to 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 consumption power of the load that consumes power within the target space, that is, the target space load 31. The target space power measurement unit 113 receives the power data transmitted by the first current sensor CS1 as the target space consumption power. Instead of this or, in addition, the target space power measurement unit 113 receives the power data (voltage data) transmitted by the first voltage sensor VS1 as the target space consumption power. Note that the above-mentioned "receiving the power data as the target space consumption power" means, for example, based on the power data (current data) transmitted by the first current sensor CS1 and the reference voltage data, or based on the voltage data transmitted by the first voltage sensor VS 1 and the 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, it may include calculating the power and setting it as the target space consumption power. Note that when each sensor is connected to the second wiring W2 or the third wiring W3, the target space consumption power also includes the power consumption of the control device 11 and the power consumption of the electric vehicle power supply device 21. The power difference setting unit 114 sets the power difference, which is the difference between the above-mentioned allowable power and the target space consumption power, as the power difference information.

[0058]

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

[0060] Here, depending on whether the control device 11 has a function of calculating the maximum supply power, the information transmitted by the power supply control unit 115 may be different. That is, first, when the control device 11 has a function of calculating the maximum supply power, the power supply control unit 115, for example, based on the above-described power difference, generates maximum supply power information indicating the maximum supply power that can be supplied by the electric vehicle power supply device 21. 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 adjusts the power by setting the 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] Or, 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 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] ​​​​​​​​​Further, 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 to be large. Further, 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 power consumption of the target space exceeding the allowable power can be reduced. 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 to be large. Further, 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 power consumption of the target space exceeding the allowable power can be reduced. 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 to be large. Further, 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 power consumption of the target space exceeding the allowable power can be reduced. That is, 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 to be large. Further, 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 power consumption of the target space exceeding the allowable power can be reduced. That is, 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 to be large. Further, 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 power consumption of the target space exceeding the allowable power can be reduced. That is, 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 to be large.

[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. 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. TIFF2025112251000002.tif30108 Table 1

[0066] Therefore, the power supply control unit 115 can set the maximum supply power so that the maximum supply power is equal to or smaller than the power difference (that is, not more than the power difference), and the power supply control unit 115 can set the maximum supply power so as not to exceed the allowable power. Therefore, the power supply control unit 115 can set the maximum supply power so that the maximum supply power is equal to or smaller than the power difference (that is, not more than the power difference), and the power supply control unit 115 can set the maximum supply power so as not to exceed the allowable power. Therefore, the power supply control unit 115 can set the maximum supply power so that the maximum supply power is equal to or smaller than the power difference (that is, not more than the power difference), and the power supply control unit 115 can set the maximum supply power so as not to exceed the allowable power. Therefore, the power supply control unit 115 can set the maximum supply power so that the maximum supply power is equal to or smaller than the power difference (that is, not more than the power difference), and the power supply control unit 115 can set the maximum supply power so as not to exceed the allowable power.

[0067] The power multiplied by the coefficient and the margin power difference obtained by subtracting the margin power are called "calculated power." Also called.

[0068] The coefficients and margin power mentioned above can be set arbitrarily by the user (user or installer, etc.). More specifically, the user may set a predetermined address on a terminal such as a smartphone. application (for example, it can be a dedicated application or can be implemented using web services) (which may be a browser application for using the The coefficient or margin power input by input operation on the PC is displayed as coefficient information or margin power. The output information is sent to the control device 11 or the electric vehicle power supply device 21 via the network. The coefficient or margin power may be set repeatedly on a predetermined schedule. That is, it may be possible to set a coefficient or margin power for each predetermined time unit of the day. (e.g., 0.5 hour units, 1 hour units, etc.) or by period unit (e.g., by day of the week, by week (units that are set in advance in the system, such as units, months, morning, afternoon, and evening) After the user sets it, the time zone or period (day of the week, week The coefficient or margin power may be set as set for each month (e.g., month). Alternatively, two or more settings with different coefficients or margin power settings may be pre-configured on the system. It may be possible to prepare a coefficient and select it according to a user operation (for example, the coefficient for night time may be The first setting is 1 or margin power is 0, and the coefficient is set to less than 1 or (For example, select from a second setting with margin power greater than 0.) In addition, Instead of the gin power, the maximum supply power may be directly set by the user. Transmission of various information from the terminal may be performed by communicating directly from the terminal with the control device 11 or the electric vehicle power supply device 21 via a network, and / or transmitted once from the terminal to the server via the network and then transmitted from the server to the control device 11 or the electric vehicle power supply device 21 via the 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, a fourth communication cable C C4. On the other hand, in the electric vehicle power supply device 2 1, a part of the functions of the above-described supply power control unit 115 is provided as a functional unit (for example, the supply power control unit 213 in FIG. 6), 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 received from the control device 11. At that time it is also possible to provide the allowable power storage unit 112 and the power difference setting unit 114 in the electric vehicle power supply device 21 or to transmit the allowable power information and the power difference information to the electric vehicle power supply device 21.

[0070] Therefore, by setting the maximum supply power of the electric vehicle power supply device 21 so that the maximum supply power is equal to or smaller 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 power supply device 21 for an electric vehicle 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 on-vehicle side power storage system 41 of the electric vehicle. It is desirable that the power supply device 21 for an electric vehicle conforms to a predetermined standard such as SAE J1772 and IEC 61851 / 62196. The electric vehicle power supply unit 212 supplies supply power (which is mainly charging power, so it can also be said to be charging power) to the on-vehicle side power storage system 41 as described above. The supply power is controlled based on the received power received in the on-vehicle side power storage system 41 according to the maximum supply power information. Note that this is not the only case, and 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 is, for example, information that instructs the supply power during a predetermined period and can be obtained. More specifically, for example, when the configuration is such that power supply with a predetermined duty ratio is performed from the power supply device 21 for an electric vehicle, the supply power instruction information may be instruction information that designates the duty ratio. The information processing unit 219 is a functional unit that manages information processing such as reception or transmission of predetermined information, reading of information from a predetermined storage unit, and storage in a predetermined storage unit in the power supply device 21 for an electric vehicle. For example, the maximum supply power information received from the control device 11 is transmitted via a communication line such as the eighth wiring W8.

[0073] ​​​​​​​​​​​​​​​​

[0074] <Configuration of electric vehicle side power storage system 41> The electric vehicle power supply control system 1 includes an electric vehicle side power storage system 4 provided in the electric vehicle. The electric vehicle side power storage system 41 includes the electric vehicle power supply device 21. A supply power receiving unit 411 receives supply power from a supply unit 212, and a storage unit 412 stores the received power. The device includes a battery 412, a receiving power control unit 413 that controls the receiving power, and an information processing unit 419. In this way, the electric vehicle power supply unit 212 of the electric vehicle power supply device 21 receives power. The received power can be stored in the storage battery 412.

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

[0076] The supplied power receiving unit 411 receives power from the electric vehicle power supply unit 212 of the electric vehicle power supply device 21. When the supplied power is AC power, the supplied power receiving unit 411 receives the supplied power. In this case, it is preferable to have an AC / DC conversion function. The power receiving unit 411 receives the supplied power under the control of the received power control unit 413, which will be described later. The received power is controlled to be a predetermined value.

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

[0078] The storage battery 412 can 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 electric vehicle side power storage system 41, for example, when the storage battery 412 has no power stored, or when the power stored in the storage battery 412 is not sufficient to operate the power storage system 41, at least a part of the received power received by the power supply receiving unit 411 is consumed and operated to charge the storage battery 412. However, the electric vehicle side power storage system 41 When the power stored in the storage battery 412 is sufficient to operate the electric vehicle side power storage system 41, the electric vehicle side power storage system 41 receives the power necessary for operation from the power charged in the storage battery 412.

[0080] The received power control unit 413 receives the maximum supply power information received from the electric vehicle power supply device 21 (for example, information indicating the duty ratio corresponding to the maximum supply power. When the control device 11 generates the maximum supply power information, the electric vehicle power supply device 21 receives this and includes being transmitted from the electric vehicle power supply device 21) 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 equipment, etc.)), and controls so that the received power (charging power) is optimal with power (current) below the maximum supplyable power.

[0081] The information processing unit 419 receives or transmits predetermined information in the electric vehicle side power storage system 41. Manages information processing such as sending, reading information from a specified memory unit, and storing information in a specified memory unit. It is a functional part.

[0082] <Modification of the First Embodiment> FIG. 7 is a diagram showing a modification of the first embodiment. Regarding the system 1, the electric vehicle power supply control system 1 is different from the electric vehicle power supply control system 1 of the first embodiment. In this modification shown in FIG. 7, the information stored in the distribution board DB in the first embodiment is The breaker EVB (for example, a ground fault breaker) for the electric vehicle power supply device 21 installed in ) is connected to the electricity meter EM.

[0083] That is, one end of the sixth wiring W6 is connected to the power meter EM so that power can be passed therethrough. The other end is connected to the power receiving part of the breaker EVB for the electric vehicle power supply device 21. It is being done.

[0084] The seventh wiring W7 has one end connected to the power supply device 21 for electric vehicles so that electric power can be passed through. The other end is connected to the power supply unit of the electric vehicle power supply device 21. It is connected to the power receiving unit 211 .

[0085] With this configuration, the work of installing a separate breaker EVB in the distribution board DM inside the target space is unnecessary. It is possible to set up a breaker EVB by only working on the power meter EM outside the target space without going through the It becomes possible.

[0086] In particular, when the sensors are provided on the second wiring W2 and the third wiring W3, Unlike the first embodiment, the power consumption of the target space includes the power consumption of the electric vehicle power supply device 21. Therefore, the control device 11 cannot detect the power consumption of the electric vehicle power supply device 21. Therefore, the power supply control unit 115 receives the electric power via the fourth communication cable CC4, for example. The power consumption information of the vehicle power supply device 21 is acquired, and the power of the electric vehicle is calculated based on the power indicated by the power difference. The maximum supply power is set to the power obtained by subtracting the power consumption of the utility power supply device 21. In this regard, as shown in FIG. When setting a large supply power, the same processing can be performed in the supply power control unit 213. That is, in the electric vehicle power supply device 21, the target The space power consumption information is received, and the electric vehicle power supply device 21 receives the space power consumption information. By acquiring the power consumption information of 21, the supply power control unit 213 can be similarly treated in

[0087] <Embodiment 2> The electric vehicle power supply control system 1 of the second embodiment is the same as the electric vehicle power supply control system of the first embodiment. 1 is a diagram showing another embodiment of the control system 1. Electric vehicle power supply control system according to a second embodiment 1, only the parts that are different from the electric vehicle power supply control system 1 of the first embodiment will be explained. Reveal.

[0088] FIG. 8 shows an electric vehicle power supply control system 1 including a power generation device 51 according to the second embodiment. 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 differs from the electric vehicle power supply control system 1 of the first embodiment in that it includes a device 51 .

[0089] FIG. 10 is a diagram showing an example of an electric vehicle power supply control system 1 according to the second embodiment. In the electric vehicle power supply control system 1 of the second embodiment, the control device 11 controls the target space power Instead of the measurement unit 113, a generated power measurement unit 116 for measuring the generated power of the power generation device 51 is provided. This is different from the electric vehicle power supply control system 1 of the first embodiment.

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

[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 energy, solar heat, heat existing in nature such as heat in the atmosphere, or biomass (organic matter derived from animals and plants). That is, it includes a so-called renewable energy power generation device or a natural energy power generation device. 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 yard (not shown). 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. 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.

[0092] 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. 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. The other end of the ninth wiring W9 may be connected to the distribution board DB.

[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. The other end of the ninth wiring W9 may be connected to the distribution board DB. 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 so that power can be energized, and the other end connected to the power receiving section of the main breaker MB built in the distribution board DB.

[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 that 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 load 31 in the target space or the power supply device 21 for the electric vehicle, the target space generated power is configured to be prioritized over the commercial power. Generally, when the power consumption in the target space is equal to or less than the target space generated power, there is no need to take in power from the commercial power, and it is possible to cover it only with the target space generated power. When the power consumption in the target space is greater than the target space generated power, only the difference is configured to be taken in from the commercial power. However, it is not limited to this. For example, when it is detected by the second current sensor CS2, the second voltage sensor CV2, etc. that the target space generated power is 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 so that the second power data can be transmitted from the second current sensor CS2 to the control device 11, and the other end is connected to the control device 11.

[0098] Similar to the first embodiment, 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 shown, but it is not limited to this, and it may be built into the distribution board DB and provided on the target wiring. .

[0099] Here, similar to the first embodiment, 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-mentioned 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 equal to or less than 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 consumable in the target space is derived from the allowable current (allowable power) of the main breaker MB, so it is the same as in the first embodiment. Also , even if the power generated in the target space is equal to or less than the allowable power value, when the power supply control unit 11 5 sets all of the power value of the power generated in the target space as the maximum supply power, the electric vehicle power supply device 21 supplies the maximum supply power to the electric vehicle, and the power consumption in the target space increases . Then, the sum of the supply power (in this case, the power generated in the target space) by the electric vehicle power supply device 21 and the power consumption in the target space may exceed the allowable power. Therefore, the margin target space power generation power obtained by subtracting the margin power from the power generated in the target space may be set as the maximum supply power .

[0102] Also, the power supply control unit 115 may be set as the power value of the maximum supply power, similar to the first embodiment, by multiplying the power value of the power generated in the target space by a coefficient that is 0 or more and 1 or less. Details may be the same as the case of multiplying the coefficient by the power difference in the first embodiment ( that is, replacing the "power difference" in the first embodiment with the "power generated in the target space"). Therefore, details are omitted.

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

[0104] ​​​As in the first embodiment, the coefficients and margin power are determined by the user (user or In the second embodiment, the configuration of the first embodiment may be changed. Instead of or in addition to this, for example, the number of people who are more likely to use the service during the daytime, including the daytime, than during other time periods. User selectable modes: relatively high power consumption or relatively low margin power This allows for a power generation device that generates a large amount of power during the day, such as a solar power generation device. This allows for charging using a large amount of generated electricity, reducing the amount of electricity purchased from the power company. Alternatively, the coefficient can be set relatively higher in the night time zone than in other time zones. The user may be able to select a mode with high or relatively low margin power. This allows surplus electricity to be sold during the daytime, for example, and used at night when electricity rates are cheaper. It will be possible to use electricity as the main source of power.

[0105] Next, the control device 11 does not have a function of calculating the maximum supply power, and the power supply device for an electric vehicle If the power supply control unit 21 has a function of calculating the maximum power supply, the power supply control unit 115 calculates, for example, the maximum The target space power generation information used to calculate the large supply power is transmitted to the electric vehicle power supply device 21. On the other hand, in the electric vehicle power supply device 21, as in the first embodiment, The power supply control unit 213 has a part of the functions of the power supply control unit 115 described above. Based on the target space power generation information received from the control device 11, the supply power control unit 115 The maximum supply power may be set in the same manner.

[0106] <Modification of the second embodiment> 11 is a diagram showing a modification of the second embodiment. Electric vehicle power supply control of this modification The system 1 is different from the electric vehicle power supply control system 1 of the second embodiment in the following respects: In this modification shown in FIG. 11, only the distribution board D in the second embodiment will be described. The breaker EVB for the electric vehicle power supply device 21 installed in B is connected to.

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

[0108] The seventh wiring W7 has one end connected to the power supply device 21 for electric vehicles so that electric power can be passed through. The other end is connected to the power supply unit of the electric vehicle power supply device 21. It is connected to the power receiving unit 211 .

[0109] With this configuration, the work of installing a separate breaker EVB in the distribution board DB inside the target space is unnecessary. It is possible to set up a breaker EVB by only working on the power meter EM outside the target space without going through the It becomes possible.

[0110] <Third Embodiment> The electric vehicle power supply control system 1 of the third embodiment is the same as the electric vehicle power supply control system of the first embodiment. A configuration in which the control system 1 and the electric vehicle power supply control system 1 of the second embodiment are combined Only the parts different from the electric vehicle power supply control system 1 of the first and second embodiments are Explain.

[0111] FIG. 12 shows an electric vehicle power supply control system 1 including a power generation device 51 according to the third embodiment. 1 is a diagram showing an example of an electric vehicle power supply control system 1 according to a third embodiment. The electric vehicle power supply control system 1 has a first current sensor CS1 as well as Similar to the electric vehicle power supply control system 1 of the second embodiment, the electric vehicle power supply control system 1 has a second current sensor CS2. The configuration of the distribution board DB may be the same as that of the second embodiment. As in the first embodiment, the control device 11 may be provided inside a distribution board. good.

[0112] FIG. 13 is a diagram showing an example of an electric vehicle power supply control system 1 according to the third embodiment. In the electric vehicle power supply control system 1 of the third embodiment, the control device 11 is the same as that of the first embodiment. In addition to having the target space power measuring unit 113, the power generation unit 51 measures the power generated in the target space. The electric vehicle power supply control system according to the first and second embodiments is different from the electric vehicle power supply control system according to the first and second embodiments in that it includes a generated power measurement unit 116 for determining the generated power. Different from Stem 1.

[0113] Here, in the third embodiment, as described above, the target space power measuring unit 113 and the power generating unit Since the power measurement unit 116 is provided, the supply power control unit 115 of the third embodiment is In addition to or instead of the processing of the supply power control unit 115 in the first embodiment or the second embodiment, This makes it possible to control the power consumption and power generation in the target space in consideration of both.

[0114] Here, as in the first and second embodiments, the control device 11 has a function of calculating the maximum supply power. The information transmitted by the supply power control unit 115 may differ depending on whether or not the power supply control unit 115 is turned on. First, when the control device 11 has a function of calculating the maximum supply power, the supply power control unit 115 calculates the maximum supply power by: For example, based on the above-mentioned target space power consumption and target space power generation, Maximum supply power information indicating the maximum supply power that can be supplied by the device 21 is generated.

[0115] More specifically, in the configuration of the second embodiment, the power generated in the target space is not necessarily large. Even if all of the power generated in the target space is set as the maximum supply power, there will be no impact. Whether assumed or not, margin power and coefficients may be used to calculate the power supply for electric vehicles. The sum of the power supplied by the power supply device 21 (in this case, the power generated in the target space) and the power consumed in the target space is Although it was assumed that the supply power control unit 115 would handle cases where the allowable power was exceeded, For example, the power difference between the allowable power and the power consumption in the target space is compared with the power generated in the target space. If the power generated in the target space is smaller than the power difference, the power generated in the target space is set as the maximum supply power. Then, the supply power control unit 115 may set the power generation amount in the target space based on the power difference, for example. When the power is large, the power difference may be set as the maximum supply power. By setting the supply power, the supply power by the electric vehicle power supply device 21 (in this case, the target The total of the space power generation and the target space power consumption can be operated without exceeding the allowable power. .

[0116] In the third embodiment, the maximum supply power is set by the margin power or coefficients may be adopted.

It is transmitted to the electric vehicle power supply device 21.
