Description

  The present invention relates to a power control system, a power control method, a power control apparatus, and a power control program for controlling an operation start time or an operation end time of an electric device.

  Conventionally, there has been proposed a power load leveling system that presents a time period during which the load of a power supply device of a power company is low during a day and prompts each customer to use power during this time period (for example, Patent Document 1).

  In the above power load leveling system, by showing each customer a time zone (recommended power usage time) when the load of the power supply device is low during the day, and encouraging the use of power in this time zone, It is described that the bottom power of the power demand can be increased. Moreover, it can be expected that the peak power will be reduced along with this, and it is described that the load of the power supply apparatus is leveled as a whole.

  In addition, the leveling of the load will lead to a reduction in the cost for the power company to control the amount of power generated by the power supply device in accordance with the power demand. It is described that if a discount is performed, a power user who is a consumer can expect to use cheap power intentionally at that time, and the power demand can be leveled more effectively.

  As an example, electric water heaters and heat pump water heaters that boil hot water using a late-night electric power contract or hourly light contract are already popular in the home. The hot water boiled using low-power electricity at the late night of the previous day (for example, between 11:00 pm and 7:00 am) is stored in a hot water storage tank, and this hot water is used for meals, showers, and bathing during the day, morning, and night. By using it, the power demand for boiling water is shifted to the midnight time of the previous day.

  In general, electric water heaters and heat pump water heaters make hot water stored in a hot water storage tank at night when power demand is low and use it during the day. As a result, the operation of the equipment shifts to the night when the power demand is smaller than that in the daytime, so that the power demand can be leveled. In addition, the cost of electricity can be reduced by using the power at night when the power charge is low for the user.

  These electric water heaters and heat pump water heaters compatible with midnight power have a clock means in their devices, and start boiling operation when the time set in advance by a contract with an electric power company comes. That is, the reserved operation is performed every day at a preset operation start time (or operation end time).

  In the future, natural energy generators such as solar power generators and wind power generators may be widely used, but it is expected that the amount of power generated by these natural energy generators will vary greatly depending on the climate and time.

  Then, technology to control power demand will become more and more important in the future. It is considered that a new system for controlling the power demand according to the fluctuating power generation amount is required in addition to the conventional system for leveling the power demand and controlling the power generation amount accordingly.

  For example, if an electric power company fluctuates the electricity bill according to the fluctuating power generation amount, the electricity bill is reduced when the power generation amount is large, and the electricity bill is increased when the power generation amount is small, and the electric power bill is changed according to the fluctuating power generation amount. Electric power demand can be controlled.

  Then, the control system of the electric equipment which controls an electric equipment via a home server is proposed (for example, refer patent document 2). This control system compares the operating conditions of a plurality of electric devices with pre-stored conditions, calculates an ideal operating pattern and controls the electric devices, and controls the home server for ideal operation. And an electric device operated based on the pattern.

  Then, as an ideal driving pattern, the electricity price menu provided by the power company (electric power supplier) is stored in the home server so that the electricity equipment is operated at a time when the electricity price is cheap, and the operation is input in advance. Compared with the conditions and calculated, the laundry dryer, rice cooker, and pot are operated during the time when electricity charges are cheap.

  For example, as described in Patent Document 1, the electric fee can be reduced by operating the electric device in a time zone where the electric fee is low, but on the other hand, there is a limitation on the time zone in which the user wants to use the electric device.

  For example, an example is shown in the current electric power company's lighting contract by time zone.

  The cheapest time for electricity bills is night time from 11:00 pm to 7:00 am the next day, and the electricity bill is about 9 yen per kWh.

  Next, the cheapest electricity billing hours are before and after nighttime power, from 5pm to 11pm and the morning and evening hours from 7am to 10am the next day. The electricity bill is about 23 yen per kWh. is there.

  In the daytime from 10:00 am to 5:00 pm, the electricity charge is high, and the summer (July 1 to September 30) per kWh is about 33 yen, and the other seasons are about 28 yen.

  When a user tries to cook for a long time using a clothes washer / dryer or dishwasher / IH cooking heater at a time when electricity charges are low, the electric device is used during the night from 11:00 pm to 7:00 am Is the cheapest.

  Therefore, when using the above-mentioned electric equipment at a low price after 10 am, the user needs to wait until 11 pm. If the user cannot wait until night due to the circumstances of the user, the electric equipment will be used in the time zone from 5 pm to 11 pm when the electricity rate is cheap.

  The difference in electricity charges is about 2.5 times that of 9 yen / kWh for night time and 23 yen / kWh for night time.

An object of the present invention is to use an electric device at a low electric charge without waiting for a time zone when the electric charge is low.

  In order to solve the above-described conventional problems, an electric power control system according to the present invention includes an electric vehicle and a power control device that controls discharge from a storage battery included in the electric vehicle and controls power supply to an electric device. An electric power control system, wherein an electric vehicle acquires a discharge information before a storage battery, a discharge information acquisition unit that acquires discharge information related to discharge of the storage battery, and the electric vehicle arrives at a place where electric power is discharged from the electric vehicle.

And a power control unit that determines the time to operate the electrical device by supplying power from the storage battery to the electrical device based on the discharge information received by the receiving unit. A.

  Thereby, the discharge information regarding the discharge of the electric power stored in the storage battery of the electric vehicle is acquired before the electric vehicle arrives, and the electric device is operated by supplying power from the storage battery to the electric device based on the discharge information. Is to determine.

  The power control system, the power control method, the power control apparatus, and the power control program thereof according to the present invention can operate the electric device by discharging the power stored in the storage battery of the electric vehicle. In addition, the operation time of the electric device can be determined before the electric vehicle arrives.

  For example, if the battery of an electric vehicle is charged at a low price for the night time of the previous day at home and the electric vehicle returns home in the evening after going out with an electric vehicle during the day, By discharging this, the electric device can be operated at an electric charge equivalent to the electric charge at night time.

  The charge / discharge information includes information regarding the current remaining amount and discharge of the in-vehicle battery 23.

  The control determination unit 11 calculates the amount of power that can be discharged from the in-vehicle battery 23 to the electric device 1 via the power feeding unit 13 according to the discharge information such as the remaining amount of the in-vehicle battery 23, and Based on the amount of electric power that can be discharged, power is supplied from the in-vehicle battery 23 to the electric device 1 via the electric power feeder 13 to determine the time when the electric device 1 is operated.

  Specifically, the control determination unit 11 reads the time from the clock unit 12 and instructs the device control unit 10 to operate the electric device 1 (for example, control of the washing operation and the drying operation of the clothes washing dryer).

  Further, the control determination unit 11 controls the discharge from the in-vehicle battery 23 via the power supply unit 13 and the charge / discharge plug 24 in association with the operation instruction of the electric device 1 to the device control unit 10.

Furthermore, the control determination part 11 can calculate the time (operation time) required for the operation of the home electric appliance 1, calculate the amount of power used for the operation, or discharge from the power consumption and the in-vehicle battery 23. Compare the amount of power.

  The electricity bill information storage unit 17 stores hourly electricity bill information regarding different electricity bills depending on the time zone.

  The control determination unit 11 performs control so that the operation control of the electric device in the device control unit 10 and the discharge from the in-vehicle battery 23 are efficiently performed based on the electricity charge information by time zone.

  Note that the efficiency mentioned here is not only to control the electricity charge to be the cheapest or the CO2 emission to be the smallest based on the electricity charge information by time zone, but also to use it. In consideration of the intent regarding the energy conservation of the person, the control that balances the electricity bill and convenience is also included.

  The electricity charge information for each time zone changes according to the time zone and the season, but in addition to this, it may be a time zone and a charge different for each contracted contractor (home or office). Also, the electricity charge information for each time zone may be a time zone and a charge that are different for each type of electric equipment that uses power (home equipment or business equipment).

  In addition, the control determination unit 11 starts discharging from the in-vehicle battery 23 based on the power supply to the electric device 1, and when the electric power discharged from the in-vehicle battery 23 becomes insufficient during the operation of the electric device 1, The power supply unit 13 switches to power supply from the grid power.

  As described above, the control determination unit 11 switches between discharging and charging of the in-vehicle battery 23 based on the operation of the electric device 1 by the power feeding unit 13. And the electric charge information classified by time slot | zone is acquired, and if there exists electric energy which can be discharged to the vehicle-mounted battery 23 in the time slot | zone when an electric bill is high, it will be discharged to the electric equipment 1. The in-vehicle battery 23 is charged in a time zone (such as nighttime) when the electricity rate is low. When charging, it may be performed simultaneously with the operation of the electric device 1 or may be performed at a time different from the operation of the electric device 1.

  The in-vehicle navigation 25 has a function of acquiring current electric vehicle position information and providing information regarding the distance to the home and information regarding the return time (expected time expected to be returned).

  The charging / discharging information detection means 22 acquires charging information including information regarding the current remaining amount and discharging of the in-vehicle battery 23, and from the information regarding the distance to the home acquired from the in-vehicle navigation 25, the battery consumed before returning home.

Yes.

  The communication path in this case is assumed to be a mobile communication network such as a mobile phone, PHS, WiFi, or WiMax, and is finally received by the second communication means 14 included in the electric device 1 installed in the house. , And taken into the control determination means 11.

There are several ways to calculate the amount of battery consumed before returning home. One is to pre-register the average consumption per kilometer specific to the electric vehicle in the charge / discharge information detecting means 22. There is a method of calculating by multiplying the amount of consumption and the distance to home.

  Another possible method is to calculate the amount of consumption per kilometer from the driving situation of the day and multiply by the distance to the home as described above.

  The in-vehicle navigation system 25 is equipped with a receiving device called a broadcast radio wave receiver and a beacon, and the expected accuracy of the battery that will be consumed up to the home is taken into account in consideration of traffic jam information expected before returning home. Further improvement is possible, and further effects can be expected.

  The same applies to the return time (scheduled arrival time at home), and it can be calculated by adding the time calculated from the distance to the home and the average speed to the current time. It is also possible to further improve the time prediction accuracy, and similarly, further effects can be expected. However, unexpected traffic jams due to sudden accidents can actually occur, but it is routinely expected that such a situation will cause the return time to be significantly behind the original schedule, such as It is desirable to control the system flexibly in response to any situation.

  Next, the operation of the power control system according to Embodiment 1 of the present invention will be described.

  FIG. 2 is an operation flowchart of the power control system, and FIG. 3 is a schematic diagram for explaining an operation time of the power control system. Hereinafter, description will be made with reference to FIGS. 2 and 3 together with FIG.

  In step S <b> 1, the control determination unit 11 determines the operation time of the household electrical appliance 1 and the amount of electric power required for the operation based on the operation conditions (the operation course and the amount of clothes of the clothes washer / dryer) set by the user using the display input unit 15. (Required electric energy) is calculated.

  In step S <b> 2, the control determination unit 11 acquires hourly electricity bill information from the electricity bill information storage unit 17.

  In step S <b> 3, discharge information including the estimated arrival time of the electric vehicle 2 received by the second communication unit 14 and the amount of electric power that can be discharged from the in-vehicle battery 23 is acquired.

  Here, the estimated arrival time of the electric vehicle 2 is calculated by the in-vehicle navigation device 25 as described above. The amount of electric power that can be discharged from the in-vehicle battery 23 is detected by the charge / discharge information detection unit 22 of the electric vehicle 2 as described above.

  Then, the estimated arrival time of the electric vehicle 2 and the amount of electric power that can be discharged from the in-vehicle battery 23 are included in the charge / discharge information and transmitted from the first communication unit 21 of the electric vehicle 2 to the second communication unit of the house.

  Next, in step S4, the control determination unit 11 determines whether the scheduled arrival time of the electric vehicle 2 is before the time zone where the electricity rate is cheaper or the time zone where the electricity rate is cheaper. Judging.

  In step S5, if the electric vehicle 2 is scheduled to arrive before the time period when the electricity rate is cheap, the amount of electric power that can be discharged from the in-vehicle battery 23 is greater or less than the amount of electric power required for the operation of the electric device 1. Determine whether.

When the electric vehicle 2 is scheduled to arrive before the time when the electricity rate is cheap and the amount of electric power that can be discharged from the in-vehicle battery 23 is larger than the amount of electric power required for the operation of the electric device 1, step S6. The control determination unit 11 sets the operation start time of the electric device 1 to the expected arrival time of the electric vehicle 2.

  As a result, as will be described in detail later, the power control system acquires discharge information related to the discharge of the in-vehicle battery before the electric vehicle arrives at the home, and after the electric vehicle arrives at the home, You can make a plan to supply electric power and operate electrical equipment. As a result, even before the time period when the electricity rate is cheap, it is possible to operate the electric device by discharging the electric power stored in the in-vehicle battery of the electric vehicle.

  For example, you can charge the battery of an electric car at home at the cheapest electricity rate the night before the day, and then you can discharge the in-vehicle battery when you go home in the evening after going out with an electric car during the day If there is electric power, the electric device can be operated at an electric charge equivalent to the electric charge at night time by discharging it.

  In step S5 described above, the electric vehicle 2 is scheduled to arrive before the time zone when the electricity charge is cheap, and the amount of electric power that can be discharged from the in-vehicle battery 23 is the amount of electric power required for the operation of the electric device 1. If it is less, in step S51, when the amount of electric power that can be discharged from the in-vehicle battery 23 is discharged to the electric device 1, the control time is determined for how long the electric device 1 can be operated from the start of operation. The part 11 calculates.

  Therefore, the control determination unit 11 stores in advance, for each elapsed time since the start of operation, the amount of power used in the operation of the electric device 1 for each operation condition that can be set by the user. Alternatively, an arithmetic expression is provided so that the amount of electric power used in the operation of the electric device 1 can be calculated for each elapsed time since the start of operation, according to the operation conditions that can be set by the user.

  In step S52, the electric vehicle 2 is discharged when the scheduled arrival time of the electric vehicle 2 is set as the operation start time of the electric device 1 and the electric device 1 is discharged to discharge the electric energy that can be discharged from the in-vehicle battery 23. Just determine whether it is possible to drive until the time when electricity charges are cheap. That is, a time obtained by adding the drivable time to the estimated arrival time is calculated, and it is determined whether or not the time is included in a time zone where the electricity rate is low.

  When the time obtained by adding the drivable time to the estimated arrival time is calculated and the time is included in the time zone where the electricity charge is cheap, the control determination unit 11 determines the operation start time of the electric device 1 in step S53. After the scheduled arrival time of the electric vehicle 2, the time is set to a time that is back by the above-mentioned drivable time from the time zone when the electric charge is low.

  As a result, although the details will be described later, the power control system acquires discharge information related to the discharge of the in-vehicle battery before the electric vehicle arrives at the home, and starts operation of the electric device immediately after the electric vehicle arrives at the home. Although it is not possible, it is possible to plan to operate the electrical equipment even before the time when electricity is cheap, by supplying power to the electrical equipment using the amount of power that can be discharged from the on-board battery. it can.

  In step S4, if the scheduled arrival time of the electric vehicle 2 is in a time zone where the electricity rate is cheap among the electricity rates by time zone, the operation start time of the electric device 1 is the electric rate in step S41. Set to a cheap time zone (for example, after 23:00).

That is, even if there is a dischargeable electric energy remaining in the in-vehicle battery of the electric vehicle 2, the electric device 1 is operated using the electric power of the system power without discharging it. Since the electric vehicle cannot arrive before the time when the electricity charge is cheap, the electric device stored in the in-vehicle battery cannot be discharged to operate the electric device. The electric device 1 is operated in a time zone where the electricity bill is cheap.

  Returning to step S7, the current time measured by the clock unit 12 is compared with the operation start time set above, and when the current time matches the operation start time, the control determination unit 11 determines that the on-vehicle battery of the electric vehicle 2 The electric power discharged from the power is supplied to the electric device 1 by the power supply unit 13, and the electric device 1 is started to operate (step S8).

  Thus, when the electric power discharged from the vehicle battery of the electric vehicle 2 is supplied to the electric device 1 by the electric power supply unit 13 and the electric device 1 is operated, the control determination unit 11 performs the charge / discharge information detection unit 22 of the electric vehicle 2. The charging state of the in-vehicle battery 23 is acquired, and when the amount of electric power that can be discharged is exceeded, the discharging is terminated and switching from in-vehicle battery discharging to system power is performed. That is, the operation is continued by switching to the grid power even when the electricity price is not cheap.

  In step S <b> 9, the control determination unit compares the current time measured by the clock unit 12 with the time zone when the electricity rate obtained from the electricity rate information storage unit 17 is reduced while operating the electrical device 1, Is matched with the time zone when the electricity rate is cheap, the control determination unit 11 switches the power supply of the electric device 1 from the discharge of the in-vehicle battery of the electric vehicle 2 to the system power by the power supply unit 13 (step S10). That is, the electric power used by the electric device 1 is switched from the in-vehicle battery 23 to the grid electric power with a low electric charge, and the operation of the electric device 1 is continued.

  Also in step 8, when the electric power discharged from the vehicle battery of the electric vehicle 2 is supplied to the electric device 1 by the electric power supply unit 13 and the electric device 1 is operated, the control determination unit 11 detects the charge / discharge information of the electric vehicle 2. It communicates with the part 22, acquires the charge state of the vehicle-mounted battery 23, and when it exceeds the electric energy which can be discharged, it switches from discharge of a vehicle-mounted battery to system power as discharge completion. That is, the operation is continued by switching to the grid power even when the electricity price is not cheap.

  In step S11, after the operation of the home appliance 1 is completed, the control determination unit 11 switches the power supply from the system power to the charging of the in-vehicle battery of the electric vehicle 2 by the power supply unit 13 (step S12). . That is, the vehicle-mounted battery is charged with system power with a low electricity bill.

  Finally, in step S13, the control determination unit 11 communicates with the charge / discharge information detection unit 22 of the electric vehicle 2 (using the first communication unit and the second communication unit) to acquire the charge state of the in-vehicle battery 23. When the charging exceeds a predetermined value, the charging of the in-vehicle battery from the grid power is terminated as full charging.

  Note that the control determination unit 11 communicates with the charge / discharge information detection unit 22 of the electric vehicle 2 also when the electric device 1 is operated by supplying power discharged from the vehicle battery of the electric vehicle 2 to the electric device 1 by the power feeding unit 13. Then, the state of charge of the in-vehicle battery 23 is acquired, and when the amount of power that can be discharged is exceeded, the discharge is terminated and the system is switched from the in-vehicle battery discharge to the system power. That is, the operation is continued by switching to the grid power even when the electricity price is not cheap.

  The operation time of the power control system will be described with reference to FIG. 3 based on the above operation flow.

  According to the time shown on the horizontal axis, the power supply from the electric vehicle or the power supply by the system power is shown on the upper side of the vertical axis. On the lower side of the vertical axis, electric power usage by electric equipment and electric power usage by charging an electric vehicle are shown.

FIG. 3A shows that the electric vehicle 2 came home at 19:00, which is the estimated arrival time.
The case where there is no electric power that can be discharged in the in-vehicle battery 23 is shown.

  This is step S53 of the flowchart of FIG. 2, and the operation start time of the electric device 1 is set to the time when the time zone when the electric charge is cheap starts, assuming that there is no operation time of the electric device 1 with the in-vehicle battery 23 of the electric vehicle 2. It corresponds to the case.

  Since there is no electric power that can be discharged in the in-vehicle battery 23 of the electric vehicle 2 (No in step S5), there is no drivable time during which the electric device 1 can be operated (No in step S52), and the electric device 1 (washing and drying machine) The operation start time is set to a time zone (23:00) when the electricity charge of the system power is low (step S53).

  As shown in FIG. 3A, power is supplied from the grid power from 23:00 to start operation. Then, when the operation of the electric device 1 is completed, subsequently, electric power is supplied from the system power to charge the in-vehicle battery 23 of the electric vehicle 2.

  In addition, even if it waits until the time zone when the electricity charge of the system power is cheap, the operation starts from the electric device 1 as shown in FIG. 3A, or alternatively, the charging starts from the in-vehicle battery 23 of the electric vehicle 2 first. May be. For this purpose, the control determination unit 11 may be provided with a priority order for starting the electric device 1 or the in-vehicle battery 23 first, and the user may set this.

  Next, FIG. 3B shows a case where the electric vehicle 2 returns home at 19:00, which is a scheduled arrival time, and the in-vehicle battery 23 of the electric vehicle 2 has dischargeable power. And the case where the electric energy which can be discharged from the vehicle-mounted battery 23 is larger than the electric energy required for the electric equipment 1 to drive | operate is shown.

  This is step S5 in the flowchart of FIG. 2, and the amount of electric power that can be discharged from the in-vehicle battery 23 of the electric vehicle 2 is greater than or equal to the amount of electric power required for the operation of the electric device 1 (Yes in step S5). This corresponds to the case where the driving start time 1 is set to the expected arrival time of the electric vehicle 2.

  As shown in FIG. 3B, from 19:00 when the electric vehicle 2 arrives, electric power is discharged from the in-vehicle battery 23 to the electric device 1, and the electric device 1 is operated with this electric power (washing and drying). If washing and drying is completed by the time when the electricity charge is reduced (23:00), the electric power is discharged from the in-vehicle battery 23 until the electricity charge is reduced (23:00) and used by other electric devices. can do.

  Then, power is supplied from the grid power from 23:00 to charge the in-vehicle battery 23 of the electric vehicle 2.

  In this way, by discharging power from the in-vehicle battery 34 of the electric vehicle 2, the electric device can be operated from 19:00 immediately after arrival of the electric vehicle 2 and finished before 23:00.

  At this time, the in-vehicle battery 23 of the electric vehicle 2 is charged at a low electricity charge at night time the previous day, and after going out with an electric vehicle during the day, the electric battery can be discharged to the storage battery when the electric vehicle returns home in the evening. If there is electric power, the electric device can be operated at an electric charge equivalent to the electric charge at night time by discharging it. You can plan it before the electric car arrives.

Also, from 19:00 when the electric vehicle 2 arrives, electric power is discharged from the in-vehicle battery 23 to the electric device 1 and the electric device 1 is operated with this electric power (washing and drying). If the washing and drying process is not finished by), as shown in FIG. 3 (c), the home appliance 1 continues to operate by switching to the power supply from the grid power from the time when the electricity charge is reduced (23:00). . Then, when the operation of the electric device 1 is completed, subsequently, electric power is supplied from the system power to charge the in-vehicle battery 23 of the electric vehicle 2.

  Thus, in the time zone when the electricity bill is cheap, priority is given to the power supply from the grid power, and the discharge of power from the in-vehicle battery 23 is reduced. Thereby, the time taken to charge the electric power discharged from the vehicle-mounted battery 23 with the system power can be reduced.

  In addition, even if it is a time zone when electricity charges are cheap, when the electric charge that can be discharged to the in-vehicle battery 23 is cheaper, the control determination unit 11 makes the power selection so that the user can select to discharge from the in-vehicle battery 23. The electric charge of the system power when the in-vehicle battery 23 is charged via the power supply unit 13 is stored, and this is notified to the user through the display input unit 15, and the electric power to be supplied to the operation of the electric device 1 is supplied from the in-vehicle battery 23. Let the user select whether to discharge or use grid power.

    In this way, by discharging power from the in-vehicle battery 34 of the electric vehicle 2, the electric device 1 is operated from 19:00 immediately after the electric vehicle 2 arrives, and electricity is supplied from the system power from 23:00 when the electric charge is reduced. The device 1 can be operated.

  Finally, FIG. 3D shows a case where the electric vehicle 2 returns home at 19:00, which is the estimated arrival time, and the in-vehicle battery 23 of the electric vehicle 2 has electric power that can be discharged. And the case where the electric energy which can be discharged from the vehicle-mounted battery 23 is smaller than the electric energy required for the electric equipment 1 to drive | operate is shown.

  This is step S5 in the flowchart of FIG. 2, and the amount of electric power that can be discharged from the in-vehicle battery 23 of the electric vehicle 2 is not sufficient for the operation of the electric device 1 (No in step S5). Calculates the driveable time (for example, 2 hours) that can be operated with a possible amount of electric power, and even if the operation is started from the estimated arrival time (19:00), the driveable time (2 hours) is a time zone where the electricity bill is cheap ( It can be operated until (23:00) (No in Step S52), and the operation start time is equivalent to the case where the operation start time is set to 21:00, which is retroactive by a maneuverable time (2 hours) from the time zone where electricity is cheap (23:00) To do.

  As shown in FIG. 3D, after the electric vehicle 2 arrives, the electric device is discharged from the in-vehicle battery 23 to the electric device 1 from 21:00 until the time when the electric charge is reduced by this power (23:00). 1 is performed (washing and drying). When it is time (23:00) when the electricity bill becomes cheap, the home electric appliance 1 switches to power supply from the grid power and continues operation. Then, when the operation of the electric device 1 is completed, subsequently, electric power is supplied from the system power to charge the in-vehicle battery 23 of the electric vehicle 2.

  In this way, by discharging power from the in-vehicle battery 34 of the electric vehicle 2, the electric device 1 can be operated before 23:00 when the electricity bill is reduced.

  In the present embodiment, the electric vehicle 2 corresponds to an example of an electric vehicle, the in-vehicle battery 23 corresponds to an example of a storage battery, the electric water heater 1 corresponds to an example of an electric device, and the power control device 16 has electric power. The charging information detection unit 22 corresponds to an example of a charging information acquisition unit, the first communication unit 21 corresponds to an example of a transmission unit, and the second communication unit 14 corresponds to an example of a reception unit. The control determination unit 11 corresponds to an example of a power control unit, and the electricity rate information storage unit 17 corresponds to an example of an electricity rate information storage unit.

  As described above, the power control system according to the first embodiment acquires discharge information related to the discharge of the storage battery before the electric vehicle arrives at the place where the electric power is discharged from the electric vehicle, and supplies power from the storage battery to the electrical device. Thus, it is possible to determine the time when the electric device is operated, and to discharge the electric power stored in the storage battery of the electric vehicle to operate the electric device. In addition, the operation time of the electric device can be determined before the electric vehicle arrives.

  And since the electric energy which can be discharged from a storage battery is computable from the discharge information received from the electric vehicle, the precision of the time of supplying electric power from a storage battery to an electric equipment and driving an electric equipment can be improved.

  At that time, taking into account the amount of power used when moving from the current position of the electric vehicle to the place where the power control device (home, etc.) is installed, the power is supplied from the storage battery to the electric device. Since the driving time is determined, the accuracy can be improved.

  Alternatively, the electric device is operated by supplying power from the storage battery to the electric device in consideration of the estimated arrival time at which the electric power control device (such as home) is installed from the current position of the electric vehicle. Since the time is determined, the accuracy can be improved.

  The server device 3 mediates communication between the electric vehicle 2 and the power control device 16 (electric device 1).

  The in-vehicle navigation device 25 acquires current position information of the electric vehicle 2 and provides information related to the distance from the current position to the home.

  The charge / discharge information detection unit 22 acquires information related to the discharge of the in-vehicle battery 23, and the distance from the current position of the electric vehicle 2 to the place (for example, home) where the electric device 1 (power control device 16) is installed. The information regarding is acquired from the in-vehicle navigation device 25.

  The first communication unit 21 is the place where the electric device 1 (the power control device 16) is installed from the current position of the electric vehicle 2 and the information regarding the discharge of the in-vehicle battery 23 acquired by the charge / discharge information detection unit 22 Charge / discharge information including information on the distance to (for example, home) is transmitted to the server device 3.

  FIG. 6 is a diagram showing a configuration of the server device 3 shown in FIG.

The server device 3 includes a distance information receiving unit 31, a remaining amount calculating unit 32, an estimated arrival time calculating unit 33, and a transmitting unit 34.

  The distance information receiving unit 31 is information related to the current remaining amount of the in-vehicle battery 23, and information related to the current position of the electric vehicle 2 and the position where the electric device 1 (power control device 16) is installed (for example, home). The charging / discharging information including is received from the electric vehicle 2.

  Based on the received information regarding the current remaining amount of the in-vehicle battery 23 and the received information regarding the distance between the current position and the home position, the remaining amount calculating unit 32 calculates the remaining amount of the in-vehicle battery 23 at the time of arrival at home. calculate.

  Specifically, the remaining amount calculation unit 32 calculates the amount of power consumed by the in-vehicle battery 23 before arrival at the home, based on the received information on the distance from the current position to the home.

  The remaining amount calculation unit 32 subtracts the calculated power consumption consumed by the in-vehicle battery 23 before arrival at the home from the current remaining amount of the received in-vehicle battery 23, thereby remaining the in-vehicle battery 23 at the time of arrival at home. Calculate the amount.

  The transmission unit 34 transmits charge / discharge information including information on the remaining amount of the in-vehicle battery 23 at the time of arrival at the home calculated by the remaining amount calculation unit 32 to the power control device 16.

  Further, the estimated arrival time calculation unit 33 calculates the estimated arrival time at home based on the received information on the distance from the current position to the home. In the in-vehicle navigation system 25 according to the first embodiment, the current position information of the electric vehicle is acquired and information on the distance to the home position and information on the return time (expected time expected to be returned) are provided. It is the same function as

  The return time (scheduled arrival time at home) can be calculated by adding the time calculated from the distance to the home and the average speed to the current time. In addition, the server device can acquire traffic congestion information on the road from the traffic information server which is another server device, and can calculate the estimated arrival time in consideration of traffic congestion information expected before returning home, Further effects can be expected.

  The second communication unit 14 of the power control device 16 includes charging information including the remaining amount information and the estimated arrival time transmitted by the transmission unit 34 before the electric vehicle 2 arrives at a place where power is supplied to the electric vehicle 2. Receive discharge information.

  Note that the processing of the control determination unit 11 is the same as that of the first embodiment, and thus description thereof is omitted.

  As described above, according to the second embodiment, the electric vehicle 2 or the power control device 16 does not need to calculate the remaining amount of the in-vehicle battery 23 or the estimated arrival time at the time of arrival at the installation place, and thus the electric vehicle. 2 and processing in the power control device 16 can be reduced.

  As a result, the power control device (home, etc.) is generated from the current usage position of the electric vehicle and the current position of the electric vehicle when the server device moves from the current position of the electric vehicle to the installation location where the power control device (home, etc.) is installed. Since at least one estimated arrival time arriving at the installed location is calculated, it is possible to increase the accuracy of the time when the electrical device is operated by supplying power from the storage battery to the electrical device.

(Embodiment 3)
FIG. 6 is a block diagram showing an example of the configuration of the power control system according to Embodiment 3 of the present invention.

  Compared with FIG. 1 of Embodiment 1, in FIG. 1, the electric power control apparatus 16 was built in the electric equipment 1, but it was set as the structure isolate | separated in FIG. And the electric equipment 1a and the electric equipment 1b were shown by making the electric equipment which the control determination apparatus 11 of the electric power control apparatus 16 controls into two or more. Note that there may be three or more electrical devices.

  In the first embodiment, the electric power control device 16 has a low electric charge for operating one electric device 1 by supplying power from the in-vehicle battery 23 of the electric vehicle 2 or by supplying power from the grid power. The control determination unit 11 determines from the time zone and the estimated arrival time of the electric vehicle 2, and the power supply unit 13 switches the supply power.

  In the third embodiment, there are a plurality of electric devices. Similarly, the power control device 16 operates the electric device 1a and the electric device 1b by supplying electric power from the in-vehicle battery 23 of the electric vehicle 2 or the system. The control determination unit 11 determines whether to operate by supplying power from the time zone where the electricity rate is low and the scheduled arrival time of the electric vehicle 2, and the power supply unit 13 switches the supply power.

  Therefore, the configuration of the power control system in FIG. 6 will not be described for the same parts as in FIG. The operation flow is the same as that in FIG. 2 of the first embodiment.

  Therefore, the operation time of the power control system based on the operation flow is the same as that in FIG. Here, since there are a plurality of electric devices, as shown in FIG. 7, the electric device 1a (washing and drying machine) is operated with the electric power discharged from the electric vehicle 2, and then the electric device 2 (dishwasher) 1b is operated. After driving with the discharge power from the electric vehicle 2, when it becomes a time zone where the electricity charge is cheap (23:00), the electric device 2 is operated with the system power, and when it is finished, the electric vehicle 2 is operated with the system power with the cheap electricity charge. This makes it possible to plan operation such as charging a vehicle battery.

  Note that the priority order of the electric device 1a or the electric device 1b to be operated first may be provided in the control determination unit 11 and set by the user. Depending on the priority setting, the in-vehicle battery 23 is charged by the grid power before the operation of the electrical equipment 1b, and waits for a time period when the electricity price is cheap, and after that, the electrical equipment 1b is charged by the grid power with a low electricity price. You may drive.

  Further, the power control unit 11 is necessary for the electric devices to be operated by comparing the amount of electric power that can be discharged from the in-vehicle battery 23 with the electric energy required for the electric devices to operate in a plurality of electric devices. You may make it give priority to electric power supply to the electric equipment in which the electric energy to perform is in the range of the electric energy which can be discharged from a storage battery. Thereby, when power is supplied from the storage battery to the electrical device and the electrical device is operated, priority can be given to the electrical device that can be operated with the amount of power that can be discharged from the storage battery.

  Such a power control device 16 can be realized by an information processing device such as a personal computer. It can also be realized as a software program that causes a personal computer to operate as a power control device.

  In the first to third embodiments, the example of the time period when the electricity rate is low has been described with the electric lamp contract according to time period, but the present invention is not limited to this.

For example, there are countries that have adopted a real-time pricing system in areas where solar power generation devices and wind power generation devices are spreading. This is because the electricity contract by time of day reduces the electricity bill at a fixed time of 11:00 pm to 7:00 am every day, whereas real-time pricing depends on the amount of power generated by the solar power generator or wind power generator, etc. The electricity rate fluctuates in real time, and the electricity rate fluctuates depending on the day even in the same time zone. The electricity company announces to the user the electricity charges for 24 hours after the current time for the changing electricity charges.

  Therefore, the electricity rate information storage unit 17 that stores electricity rate information related to the electricity rate that differs according to the time zone, which the power control device 16 has, communicates with the server device of the power company up to 24 hours ahead of the real-time pricing. Electricity rate information is acquired so that the control determination unit 11 can use it.

  In addition, it is preferable to constantly or periodically communicate information regarding the remaining amount of the in-vehicle battery 23 that changes every moment while the electric vehicle 2 is traveling. There is no problem, and communication may be performed when the electric vehicle starts (when it gets on) or when it ends (when it gets off).

  In the present embodiment, the installation location of the charging device has been described as a home. However, the present invention is not limited to this, and any location where electric vehicles can be parked and discharged can be used, such as a parking lot in a store or commercial facility, an office, or a factory. It is even better if it can be charged and discharged.

  Note that the specific embodiments or examples made in the section for carrying out the invention are to clarify the technical contents of the present invention, and are limited to such specific examples. The present invention should not be interpreted in a narrow sense, and various modifications can be made within the spirit and scope of the present invention.

  As described above, according to the present invention, it is possible to use an electric device at a low electric charge without waiting for a low electric charge time period using a storage battery of an electric vehicle, considering convenience and economy. The present invention is useful as a power control system, a power control method, a power control apparatus, a power control system, a power control method, and a power control program for controlling power supply to an electrical device.
