Patent No. 5983237

  By the way, when driving an electric device of a house using an on-board battery of a vehicle (electric vehicle) such as an electric car or a hybrid car, based on the remaining amount (for example, SOC: State of charge) of the electric energy in the on-vehicle battery The electrical energy of the onboard battery is used. In this case, when the vehicle returns from the outside, the amount of remaining electricity of the on-board battery at the present time is calculated, and power supply from the on-board battery to the electric device in the house is performed based on the remaining amount of electricity. More specifically, the home-side power control device receives the SOC from the vehicle side in a cable-connected state to the vehicle after the vehicle comes home, and if the SOC is equal to or higher than a predetermined value, it replaces the commercial power. The battery power is used to drive the electrical device.

  However, in the configuration in which the SOC of the on-board battery is received from the vehicle side with the cable connection between the home side and the vehicle side after the vehicle returns home as described above, the electric energy of the on-board battery can not be used effectively. It is possible that the electric energy of the on-board battery can not be used as much as expected and power shortage may occur. In recent years, public charging infrastructure has been in place, and under such circumstances, it may be possible for the vehicle to return home with the on-board battery close to full charge. It is thought that there are times when it remains without being available. The above-mentioned inconvenience can not be solved at all even in Patent Document 1, and it is considered that there is room for technical improvement.

  The present invention has been made in view of the above-mentioned circumstances, and it is mainly to provide a power control apparatus of a house which can effectively use electric energy remaining in a storage battery of a vehicle for driving an electric device in the house. It is the purpose.

  Hereinafter, means, etc. effective for solving the above-mentioned problems will be described while showing actions, effects and the like as necessary. In the following, for ease of understanding, the reference numerals of the corresponding configurations in the embodiment of the invention are appropriately shown in parentheses, but the present invention is not limited to the specific configurations shown in the parentheses, etc.

The first invention is
In a house (10) equipped with an electric device (14), the electric power of the house applied to a house power system capable of supplying power from a storage battery (31) mounted on a vehicle (30) to the electric device A control unit (20),
A storage amount acquiring unit for acquiring the storage amount remaining in the storage battery before returning to the house from the place where the vehicle is on the way;
A burden setting unit configured to set a power burden amount of the vehicle on the electric device after the vehicle returns from the destination based on the storage amount acquired by the storage amount acquisition unit;
And the like.

  According to the power control device configured as described above, the storage amount remaining in the storage battery is acquired before the vehicle returns from the outside to the house, and based on the acquired storage amount, the electric device after the vehicle returns from the outside The electric power burden amount of the vehicle for the In this case, in other words, before returning home, the amount of electrical energy to be brought back when returning home is predicted, and power management after returning of the vehicle is performed based on the predicted amount of electrical energy.

  Here, if the storage amount of the storage battery is acquired on the housing side after the vehicle returns home, for example, although the storage amount remaining in the storage battery is large, the usage amount is limited to a small amount, and the storage battery It is possible that the electric energy of the above can not be used effectively. In this respect, as described above, before the vehicle returns from the place of departure to the home, the amount of stored power remaining in the storage battery is acquired, and based on the obtained amount of stored electricity, the power burden of the vehicle after the vehicle returns from the place of departure is set. By doing this, the power management can be properly performed after grasping in advance the electrical energy that the vehicle brings back to the house. As a result, the electric energy remaining in the storage battery of the vehicle can be effectively used to drive the electric device in the house.

  According to a second aspect of the present invention, based on the position acquisition means for acquiring the position of the vehicle at the destination, the storage amount acquired by the storage amount acquisition means, and the vehicle position acquired by the position acquisition means. Storage amount predicting means for predicting the storage amount of the storage battery when the vehicle returns from the home to the house as the storage amount at the time of returning home, and the burden amount setting means is configured to estimate the storage amount predicted by the storage amount estimation means It is characterized in that the amount of electric power burden is set based on the amount of stored electricity when returning home.

  Based on the vehicle position and storage amount at home, the storage amount of the storage battery when the vehicle returns from home to the residence is predicted as the storage amount at return home, and the electric power burden of the vehicle is calculated based on the storage amount at home. It was made to set. In this case, if the vehicle position and storage amount at the place of departure are known, it is possible to predict the storage amount when returning home, taking into consideration the amount of electricity consumed by the vehicle before returning to the house. For example, power management can be performed more properly after the vehicle returns home.

  The third invention comprises return time prediction means for predicting a return time to return to the house before the vehicle returns to the house from the place of departure, and the burden amount setting means is acquired by the storage amount acquisition means The electric power burden amount is set based on the storage amount and the return time predicted by the return time prediction means.

  The electric power burden amount of the vehicle is set based on the storage amount of the storage battery acquired before the vehicle returns to the house from the place of departure and the return time estimated before the vehicle returns to the house from the place of departure. In this case, if the return time of the vehicle is known in advance, the electrical energy of the storage battery with respect to the electric device driven after returning home while sorting the electric device driven before returning home and the electric device driven after returning home Can be used effectively.

  In the fourth invention, the burden setting unit uses the time series pattern of all day or a predetermined time zone concerning power consumption in the house, and the power burden is based on the return time predicted by the return time prediction unit. It is characterized by setting an amount.

  The power burden amount of the vehicle is set based on the return time (predicted time) of the vehicle using the time series pattern of the all day or the predetermined time zone regarding the power consumption in the house. Here, in the house, it is possible to obtain in advance a time series pattern such as which time zone the power consumption becomes large, and according to the time series pattern and the return time of the vehicle, to set the power burden appropriately Can.

  According to a fifth aspect of the present invention, the burden amount setting unit is configured such that the ratio of the power that the storage battery bears on the electric device driven after the vehicle returns home is as the return time predicted by the return time prediction unit is later. The power burden amount is set to be large.

  It is conceivable that the later the return time of the vehicle is, the shorter the time in which the power supply from the vehicle side to the home side becomes possible after the return of the vehicle. In this respect, as the return time when the vehicle is predicted to return to the house is later, the electric power burden of the storage battery of the vehicle relative to the electric device driven after the return of the vehicle is larger. Therefore, even if the power supply time from the vehicle side to the home side is short after the vehicle returns home, the power supply from the vehicle side to the home side can be performed as desired.

  A sixth aspect of the present invention is the power before return which controls the power supply to the electric device based on the storage amount acquired by the storage amount acquisition means before the return time predicted by the return time prediction means. The apparatus is characterized by comprising device control means for performing control.

  To perform power control before returning home to control the power supply to the electric device based on the storage amount of the storage battery acquired before the vehicle returns from the home to the residence before the return time (predicted time) of the vehicle I made it. In this case, in anticipation of the power supply after the vehicle returns home, the power supply to the electrical device (drive of the electrical device) is limited before returning home, and conversely, the power supply after the vehicle returns home is not expected. Before returning home, the power supply to the electrical device (driving of the electrical device) may not be restricted.

  In a seventh aspect of the invention, the device control means is scheduled before the return time predicted by the return time prediction means when the storage amount acquired by the storage amount acquisition means is equal to or greater than a predetermined amount. The power supply to the predetermined electric device is changed after the return time, and the electric device is supplied with power from the storage battery after the vehicle returns.

  When the storage amount of the storage battery acquired before the vehicle returns from the place of departure to the house is equal to or more than a predetermined amount, the power supply to the predetermined electric device scheduled before the return time (predicted time) of the vehicle is returned It changed after the time and was made to supply electric power from the storage battery to the said electric equipment after the return of the vehicle. Thereby, in a house, consumption of commercial power can be suppressed, for example.

  In an eighth aspect of the invention, the storage amount acquiring unit acquires the storage amount at a predetermined cycle before the vehicle returns to the house from the place of departure, and the burden amount setting unit stores the storage amount by the storage amount acquiring unit. Each time an amount is acquired, the power burden amount is set.

  Before the vehicle returns from the place of departure to the house, the storage amount of the storage battery is acquired at a predetermined cycle, and the power burden amount of the vehicle is set each time the storage amount is acquired. In this case, even if the amount of stored electricity decreases due to discharge when the vehicle is traveling at the destination, or the amount of stored electricity increases due to charging, the power burden amount of the vehicle can be appropriately determined while sequentially grasping the change in the stored amount It can be updated, and hence proper power management can be realized.

  The ninth invention is a return home determination means for determining that the vehicle has returned to the house, and when it is determined that the vehicle has returned to the house, power supply from the vehicle to the house is scheduled. In this case, it is characterized in that it comprises notification processing means for performing notification processing for prompting connection of the electric cable (18) between the vehicle side and the housing side.

  If it is determined that the vehicle has returned to the house, and if the electric power supply from the vehicle side to the house side is scheduled, notification processing is performed to urge the connection of the electric cable between the vehicle side and the house side. Thereby, after the return of the vehicle, it is possible to properly perform the power supply from the vehicle side to the housing side.

  In a tenth aspect of the invention, when it is determined that the vehicle has returned to the house, and the notification process is performed, the vehicle and the house are at a timing when the door (19) of the door of the house is unlocked. Cable connection determination means for determining whether or not the side is connected by the electric cable, and when the cable connection determination means determines that the electric cable is not connected, the notification process is performed again And second notification processing means.

  When it is determined that the vehicle has returned to the house and the notification process is performed, whether the vehicle side and the house side are connected by the electric cable at the timing when the door of the house entrance is unlocked If it is determined that the electric cable is not connected, the notification process is performed again. Thus, after the vehicle returns home, it is possible to more appropriately perform the power supply from the vehicle side to the housing side.

The figure which shows the outline of the whole system. The flowchart which shows the process sequence of the electric power control in a house. The flowchart which shows the process sequence which implements the alerting | reporting regarding the electric power supply from the vehicle side at the time of the vehicle return home. The time chart which explains the power control in a house more concretely.

  An embodiment of the present invention will be described below based on the drawings. The present embodiment embodies a power management system in a house, in which power can be bidirectionally transferred between the house side and the car side, and power management at that time is possible. It is supposed to be. Further, the power management system enables cooperation with a vehicle management system that manages the state of a vehicle, and performs power management in a house using vehicle information from the vehicle management system. FIG. 1 is a schematic view showing the configuration of the entire system.

  In FIG. 1, commercial power of AC 100 V / 200 V is supplied to a house 10 from a utility pole or the like (not shown) via a transmission line 11. A distribution board 12 is connected to the power transmission line 11. In addition to the known distribution function of selectively supplying power to a plurality of power paths provided in house 10, distribution board 12 has a charging power supply function of supplying vehicle charging power to vehicle 30. have. A plurality of electrical devices 14 are connected to the distribution board 12 via the electrical wiring 13. The electric device 14 includes a lighting fixture, an air conditioner, a television, a refrigerator, a hot water supply device, a washing machine, a dryer, and the like. Each of these electric devices 14 is appropriately operated by the supply of power from the distribution board 12. The electric wiring 13 is provided with a power monitoring device 15 that monitors the amount of power supplied from the distribution board 12 to the electric devices 14. The power monitoring device 15 includes, for example, a known power meter.

  Further, a charging facility 17 is connected to the distribution board 12 via an electric wiring 16. The charging facility 17 is provided near the parking space of the vehicle 30 and supplies power to the vehicle 30 to charge the battery 31 mounted on the vehicle 30. The parking space is provided on the side of the house 10 in the same site as the house 10. The vehicle 30 is an electric powered vehicle such as a PHV (plug-in hybrid) vehicle or an electric vehicle, and includes a battery 31 which is a large capacity secondary battery (storage battery) as a power source of a traveling motor.

  The charging facility 17 includes an electrical cable 18 that enables the flow of power. With the electrical cable 18 connected to the inlet 32 of the vehicle 30, power is supplied from the charging facility 17 to the vehicle 30 through the electrical cable 18.

  Moreover, in the state where the electric cable 18 is connected to the vehicle 30, in addition to the power supply from the house 10 side to the vehicle 30 side, the power supply from the vehicle 30 side to the house 10 side is possible. That is, in a state where the battery 31 is stored, power can be supplied from the battery 31 to the housing 10 side. In this case, in a situation where electric power is supplied from the vehicle 30 side to the housing 10 side, the electric power is supplied to the distribution board 12 via the charging facility 17 and the electric wiring 16 and from the distribution board 12 to each electric equipment 14 Power supply is possible.

  A door 19 is provided at the entrance of the house 10, and through the door 19, the resident can enter and leave the house 10.

  The house 10 is provided with a house control device 20 that performs power management in the house 10. The house control device 20 is an electronic control device equipped with a microcomputer having a CPU and various memories. The house control device 20 performs power control to drive the electric device 14 with the supplied power from the battery 31 of the vehicle 30 in a state where the house 10 side and the vehicle 30 side are connected via the electric cable 18. In this case, in a situation where power can be supplied from the battery 31, the electric device 14 is driven using battery power instead of commercial power.

  The home control device 20 can mutually communicate with the home management management server 42 provided in the home management center 41. The management server 42 constructs an information communication network with a plurality of houses 10, stores and holds various information transmitted from each house 10, and transmits information possessed by the management server 42 to each house 10 It is possible to

  In addition, the vehicle 30 includes an on-vehicle control device 33 that manages the state of the battery 31. The on-vehicle controller 33 sequentially calculates SOC (remaining amount of electricity) indicating the amount of stored power of the battery 31 in the vehicle driving state. Regarding SOC calculation Specifically, the on-vehicle control device 33 calculates the SOC based on the open circuit voltage (OCV) of the battery 31 in the current interruption state in which the current supply to the battery 31 is interrupted, and The SOC is successively updated by integrating the current flow of the battery 31 at a predetermined cycle during charging or discharging). In addition, it is also possible to use things other than SOC as a parameter | index which shows the electrical storage amount of the battery 31. FIG. In addition, the vehicle 30 has a position recognition function of recognizing the vehicle position from the position detection result by GPS or the like and the map information.

  The in-vehicle control device 33 can mutually communicate with a management server 44 for vehicle management provided in the vehicle management center 43. The management server 44 constructs an information communication network with a plurality of vehicles 30, stores and holds various information transmitted from each vehicle 30, and transmits information possessed by the management server 44 to each vehicle 30. It is possible to

  Further, in the house management center 41 and the vehicle management center 43, cooperation between the management servers 42 and 44 is possible, and in the house management server 42, acquisition of information from the vehicle management server 44 is possible.

  In the present embodiment, when the vehicle 30 is in the traveling state (in-use state), the position information and the storage amount information (battery SOC) of the vehicle 30 are sequentially transmitted from the vehicle 30 to the vehicle management server 44. For example, in a state where the start switch (IG switch) of the vehicle 30 is on, the position information and the storage amount information of the vehicle 30 are sequentially transmitted to the vehicle management server 44 every predetermined time. Then, the vehicle management server 44 stores the received information in the storage unit (memory) for each vehicle 30. The vehicle position is stored as a position on the map.

  When the vehicle 30 is outside the house, the house control device 20 stores the vehicle stored in the vehicle management server 44 via the house management server 42 before the vehicle 30 returns to the house 10 from the outside. The position information and the storage amount information of 30 are acquired, and the electric power burden of the vehicle 30 with respect to the electric device 14 after the vehicle 30 returns from the outside is set based on the position information of the vehicle 30 and the storage amount information. In the present embodiment, the house control device 20 corresponds to a storage amount acquisition unit and a burden amount setting unit.

  FIG. 2 is a flowchart showing the processing procedure of power control in the house 10, and this process is repeatedly performed by the house control device 20 at a predetermined cycle.

  In FIG. 2, in step S11, it is determined whether the vehicle 30 is out. For example, when it is determined that the vehicle 30 is present other than at home based on the position information of the vehicle 30, step S11 is affirmed. A vehicle detection sensor may be provided in the parking space of the house 10, and it may be determined whether the vehicle 30 is out based on the detection result of the sensor. If step S11 is affirmed, it will progress to step S12, and if it is denied, it will progress to step S21.

In step S12, it is determined whether it is a timing to acquire information on the battery SOC and the vehicle position from the vehicle 30. In the present embodiment, information such as the battery SOC is to be acquired at a predetermined cycle, and if one cycle (for example, one hour) has passed since the time of departure of the vehicle 30 or the previous information acquisition time, Step S12 is affirmed. If it is the information acquisition timing, the process proceeds to step S13. If not, the present process is temporarily ended. Note that any of the following timings may be used as the information acquisition timing.
-Let acquisition time (for example, 5:00 pm) predetermined by the user be information acquisition timing.
· The timing at which the SOC acquisition command is generated by the user operation is taken as the information acquisition timing.
-When the return time of the vehicle 30 is known, the timing before a predetermined time (for example, one hour) before the return time is set as the information acquisition timing.

  In step S13, the current position of the vehicle 30 is acquired, and in step S14, the battery SOC of the vehicle 30 is acquired. These pieces of information are acquired from the vehicle management server 44 via the home management server 42.

  In step S15, the return time of the vehicle 30 to return to the house 10 is predicted. At this time, when the return time of the vehicle 30 is preset by the user operation, the return time is read. In addition, the return time may be corrected based on the current position of the vehicle 30. For example, when the destination of the vehicle 30 is known, if the destination and the current position of the vehicle 30 are different, the return time is corrected. In addition, when the return time is not set, the return time may be predicted based on the time required for the vehicle 30 to travel from the current position to the house 10.

  Thereafter, in step S16, the battery SOC at the time when the vehicle 30 comes home is predicted as the home SOC (ie, the amount of stored electricity at home). At this time, based on the battery SOC acquired this time and the consumption SOC required for the vehicle 30 to travel from the current position to the house 10, the return SOC is predicted. The consumption SOC may be calculated based on the distance between the current position of the vehicle 30 and the house 10 and the amount of power consumption required for the traveling.

  Thereafter, in step S17, before returning home power control is performed to control the power supply to the electric device 14 based on the battery SOC before the returning home time predicted in step S15. In this pre-return power control, in order to reduce the consumption of commercial power in the house 10, the power supply to the electric device 14 is expected (the driving of the electric device 14) before the return of the vehicle 30 in anticipation of the power supply after the vehicle 30 returns. However, the power supply to the electric device 14 (driving of the electric device 14) is not restricted before the return of the vehicle 30 after the vehicle 30 returns home.

  As the power control before returning home, when the battery SOC acquired in step S14 is equal to or more than a predetermined value, the drive of the predetermined electric device 14 scheduled before the returning time of the vehicle 30 is changed after the returning time The electric device 14 may be supplied with power from the battery 31 after the vehicle 30 returns home. For example, when driving a washing machine or a dryer, the driving is changed after the time of returning home, and the washing machine or the dryer is driven by power supply from the battery 31.

  Note that power control before returning may be performed based on the returning SOC (predicted SOC upon returning home) calculated in step S16. That is, the configuration may be such that the drive of the predetermined electric device 14 scheduled before the return time of the vehicle 30 is changed after the return time when the SOC at the time of return is equal to or higher than a predetermined value.

  Thereafter, in step S18, the amount of power burden by the battery 31 after the vehicle 30 has returned home is set. The power burden indicates the amount of power consumed by the battery power of the vehicle 30 among the power consumption consumed by the house 10, and battery power is consumed within the range of the power burden. The power burden may be set by the process described below.

  (1) The power burden amount is set based on the SOC at the time of returning home predicted at step S16. In this case, the use of battery power is permitted on the condition that the return SOC is equal to or greater than a predetermined reference value, and at the time of the permission, the power burden is increased as the return SOC is larger.

  (2) The power burden amount is set based on the battery SOC acquired in step S14 and the return time of the vehicle 30 predicted in step S15. In this case, the use of battery power is permitted on the condition that the battery SOC is equal to or higher than a predetermined reference value, and at the time of the permission, the power burden of the battery 31 is set in consideration of the return time of the vehicle 30. Specifically, among the plurality of electrical devices 14 in the house 10, the electrical device 14 driven after the return of the vehicle 30 is grasped based on the return time of the vehicle 30, and the electrical device 14 driven after the return of the vehicle 30 The power supply amount from the battery 31 is set, and the power burden amount of the battery 31 is set. At this time, the power burden amount is increased as the battery SOC is larger. In addition, it is also possible to use SOC when returning home instead of the battery SOC.

  (3) Using the time-series pattern of all day (24 hours) related to the power consumption in the house 10, the power burden amount is set based on the time when the vehicle 30 returns home. In this case, an all-day time-series pattern of power consumption in the house 10 is obtained in advance, and the power-consumption amount of the vehicle 30 is set by collating the time-series pattern with the return time of the vehicle 30. Also in this case, similarly to the above, the use of the battery power may be permitted on the condition that the battery SOC (or the SOC at the time of returning home) is equal to or more than a predetermined reference value.

  The power burden amount of the vehicle 30 may be set such that the power ratio of the battery 31 to the electric device 14 driven after the return of the vehicle 30 becomes larger as the return time of the vehicle 30 later. That is, it is conceivable that the later the return time of the vehicle 30 is later, the shorter the time during which the electric power can be supplied from the vehicle 30 to the house 10 after the return to the vehicle. Set the amount.

  The time series pattern of power consumption may be determined based on the past power consumption history. In this case, it is preferable that a time-series pattern is determined for each house 10 based on, for example, a record of power consumption (power consumption history) in a predetermined past period. Alternatively, the time-series pattern of power consumption may be determined based on the scheduled driving time of the electric device 14 set by the user.

  It is also possible to set which of the plurality of electrical devices 14 to which the power supply to the electrical device 14 is to be charged by the battery 31 as the power burden amount. In this case, the amount of power burden may be set according to the current consumption of each electric device 14 and the number of electric devices 14 to be supplied.

  When it is determined that the vehicle 30 is not out, ie, when the vehicle 30 is parked in the home parking space, the process proceeds from step S11 to step S21, and power is supplied from the vehicle 30 in step S21. It is determined whether to do. At this time, if the electric power burden amount of the battery 31 is set before the return of the vehicle 30 and the house 10 side and the vehicle 30 side are connected by the electric cable 18, affirm step S21. The process proceeds to step S22.

  In step S22, the electric device 14 is driven by the power supplied from the battery 31 based on the power load of the battery 31. At this time, when the electric device 14 to which the power is supplied from the battery 31 is specified, the power supply to the electric device 14 is performed.

  FIG. 3 is a flowchart showing a processing procedure for performing a notification regarding power supply from the vehicle 30 side when the vehicle 30 returns home, and this process is repeatedly performed by the home control device 20 at a predetermined cycle.

  In step S31, it is determined whether the vehicle 30 has returned home. If the configuration allows information transmission from the vehicle 30 side to the house 10 side, parking information (for example, information that the vehicle shift position is operated to the parking position) indicating that the vehicle 30 is parked is operated from the vehicle 30 side It may be configured to acquire and to determine that the vehicle 30 has returned home based on the parking information. At this time, the vehicle 30 may be returned home, and it may be determined whether or not it is within a predetermined time from the return home. The predetermined time may be several minutes, for example, 5 minutes. Further, in step S32, whether or not the supply of power from the vehicle 30 to the house 10 is scheduled after the vehicle 30 returns home, that is, whether the amount of power burden is set as having the power burden on the vehicle 30 or not Determine if

  If both steps S31 and S32 are affirmed, the process proceeds to the subsequent step S33, and if any of steps S31 and S32 is denied, the present process is temporarily ended.

  In step S33, it is determined whether it is before the 1st alerting processing which urges cable connection after the return of vehicles 30 is carried out. If it is the first time to return home, step S33 is affirmed, and the process proceeds to step S34. In step S34, a first notification process is performed to urge the connection of the electric cable 18 between the vehicle 30 and the house 10. The first notification process is performed by voice or display in the parking space of the vehicle 30. As long as the information transmission from the house 10 side to the vehicle 30 side is possible, the vehicle 30 may be configured to perform the first notification process.

  Step S33 is denied after execution of the 1st information processing, and it progresses to Step S35. In step S35, it is determined whether the door 19 at the entrance of the house 10 has been unlocked. In step S36, it is determined whether the electrical cable 18 is in the unconnected state. At this time, the house control device 20 inputs an unlocking signal from the electric lock device provided on the door 19, and determines that the unlocking operation has been performed based on the unlocking signal. Also, a cable connection signal is input from the charging facility 17 and it is determined based on the cable connection signal that the electrical cable 18 is not connected.

  If both steps S35 and S36 are affirmed, the process proceeds to the subsequent step S37, and if any one of steps S35 and S36 is denied, the present process is temporarily ended.

  In step S37, a second notification process is performed to urge connection of the electric cable 18 between the vehicle 30 and the house 10. The second notification process is performed by voice or display at or near the door 19 of the house 10. For example, the second notification process may be performed using a notification function provided to the electric lock device or a display function of the interphone.

  FIG. 4 is a time chart which more specifically describes the power control in the house 10. In FIG. 4, it is assumed that the vehicle 30 is parked in the parking space of the house 10 before timing t1 and after timing t4 and the vehicle 30 is out during the period from timing t1 to t4.

  In FIG. 4, at timing t1, the vehicle 30 leaves the house 10 and goes out. In the out state, position detection and SOC calculation are sequentially performed in the vehicle 30, and information on the vehicle position and the battery SOC is sequentially stored in the vehicle management server 44.

  Then, in the home control device 20, information such as the battery SOC and the vehicle position is acquired at timings such as timing t2 and t3, etc., and the power burden after returning home on the vehicle 30 side is calculated based on the battery SOC and the vehicle position. Be done. At this time, whenever the battery SOC is acquired, the amount of electric power burden after returning home is set (updated). Here, before returning home of the vehicle 30 (before timing t4), power supply control (pre-returning power control) to the electric device 14 before returning home of the vehicle 30 is performed on condition that the battery SOC is equal to or higher than a predetermined value. Be done. At this time, for example, the drive of the predetermined electric device 14 scheduled before the return time of the vehicle 30 is changed after the return time.

  Thereafter, when the vehicle 30 returns home at timing t4, the drive control of the electric device 14 by the power supplied from the battery 31 is performed based on the power burden amount of the battery 31 calculated before returning home.

  Here, immediately after the vehicle 30 returns home, the first notification process is performed in the parking space of the vehicle 30 on condition that power supply from the vehicle 30 side to the house 10 side is scheduled (timing t5) . Then, the connection of the electric cable 18 is performed by the user (timing t6). Thereafter, power supply from the vehicle 30 to the house 10 is appropriately performed in a cable connection state. Although illustration is omitted, after the execution of the first notification processing, the electric cable 18 is in the unconnected state at the timing when the door 19 of the house 10 is unlocked. A second notification process is performed at or near the door 19.

  According to the configuration of the embodiment described above, the following excellent effects can be obtained.

  If the configuration is such that the battery SOC is acquired on the home 10 side after the vehicle 30 returns home, for example, although the amount of stored power remaining in the battery 31 is large, the amount used is limited to a small amount. It is conceivable that electrical energy can not be used effectively. In this respect, as described above, before the vehicle 30 returns to the house from the outside, the battery SOC is acquired, and the electric power burden of the vehicle 30 after the vehicle 30 returns from the outside is set based on the acquired battery SOC. As a result, power management can be appropriately performed after grasping in advance the electrical energy that the vehicle 30 takes back to the house 10. That is, before the vehicle 30 comes home, it is possible to predict the amount of electric energy to be brought back when returning home, and to perform power management after the vehicle 30 comes home based on the electric energy amount. As a result, the electric energy remaining in the battery 31 of the vehicle 30 can be effectively used to drive the electric device 14 in the house 10. In this case, the consumption of commercial power in the house 10 can be minimized.

  Based on the vehicle position at the place of departure and the battery SOC, the battery SOC when the vehicle 30 returns to the house 10 from the place of departure is predicted as the SOC at the time of returning home, and the electric power burden of the vehicle 30 is set based on the SOC at the time of returning home. It was made to do. In this case, if the vehicle position at the place of departure and the battery SOC are known, the SOC at the time of returning home can be predicted in consideration of the amount of electricity consumed by the vehicle 30 before returning to the house 10. For example, the power management after the return of the vehicle 30 can be performed more properly.

  Based on the battery SOC acquired before the vehicle 30 returns to the house 10 from the place of departure and the return time of the vehicle 30 predicted before the vehicle 30 returns to the house 10 from the place of departure, the power burden of the vehicle 30 is set. did. In this case, if the return time of the vehicle 30 is known in advance, the electric device 14 to be driven before returning home and the electric device 14 to be driven after returning will be distributed to the electric device 14 to be driven after returning home. The electrical energy of the battery 31 can be effectively used.

  The power burden amount of the vehicle 30 is set based on the all-day time-series pattern of power consumption in the house 10 based on the time when the vehicle 30 returns home (predicted time). Here, in the house 10, it is possible to obtain in advance a time series pattern such as at which time zone the power consumption is increased, and according to the time series pattern and the returning time of the vehicle 30, the power burden amount is properly set. can do.

  It is conceivable that the later the return time of the vehicle 30 is later, the shorter the time during which power supply from the vehicle 30 to the house 10 becomes possible after the return of the vehicle 30 becomes shorter. In this respect, the power burden amount of the vehicle 30 is set such that the power ratio that the battery 31 bears on the electric device 14 driven after the vehicle 30 comes home increases as the return time of the vehicle 30 is later. Therefore, even if the power supply time from the vehicle 30 side to the house 10 side is short after the vehicle 30 returns home, the power supply from the vehicle 30 side to the house 10 side can be performed as desired.

  Before returning home (predicted time) of the vehicle 30, based on the battery SOC acquired before the vehicle 30 returns from the outside to the house 10, the power control before returning home to control the power supply to the electric device 14 is performed It was made to do. In this case, the power supply to the electric device 14 (driving of the electric device 14) is limited before returning home in anticipation of the power supply after the vehicle 30 comes home, or the power supply after the vehicle 30 returns home It is possible not to limit the power supply to the electric device 14 (driving the electric device 14) before returning home.

  If the battery SOC acquired before the vehicle 30 returns to the house from the outside is greater than a predetermined value, the power supply to the predetermined electric device 14 scheduled before the return time (predicted time) of the vehicle 30 is The change is made after the return time, and the electric device 14 is made to supply power from the battery 31 after the vehicle 30 returns. Thereby, in the house 10, for example, consumption of commercial power can be suppressed.

  Before the vehicle 30 returns from the place of departure to the house 10, the battery SOC is acquired in a predetermined cycle, and the power burden amount of the vehicle 30 is set each time the battery SOC is acquired. In this case, even if the battery SOC decreases due to discharge when the vehicle is traveling at the destination, or even if the battery SOC increases due to charge, the power burden amount of the vehicle 30 is appropriately updated while sequentially grasping the SOC change due to charge / discharge. Proper power management can be realized.

  When it is determined that the vehicle 30 has returned to a house, if the supply of power from the vehicle 30 to the house 10 is scheduled, a first notification to promote connection of the electric cable 18 between the vehicle 30 and the house 10 It was made to carry out processing. Thereby, after the return of the vehicle 30, the power supply from the vehicle 30 to the house 10 can be properly performed.

  When it is determined that the vehicle 30 has returned to the house 10 and the first notification process is performed, the vehicle 30 side and the house 10 side are electric cables at the timing when the door 19 at the entrance of the house 10 is unlocked. If not connected by 18, the second notification process is performed. Thereby, after the return of the vehicle 30, it is possible to more appropriately perform the power supply from the vehicle 30 side to the house 10 side.

  The present invention is not limited to the above embodiment, and may be implemented, for example, as follows.

  In the above embodiment, the information on the house 10 side is managed by the house management server 42 of the house management center 41, while the information on the vehicle 30 side is managed by the vehicle management server 44 of the vehicle management center 43. Although information on the vehicle 30 side (battery SOC, vehicle position, etc.) is transmitted to the house 10 side through 44, this may be changed. For example, the configuration may be such that direct communication is performed between the house control device 20 and the on-vehicle control device 33. In this case, the home control device 20 appropriately acquires the information on the battery SOC and the vehicle position from the on-vehicle control device 33.

  In the case of setting the power burden amount of the vehicle 30 based on the return time (predicted time) of the vehicle 30 using the all-day time-series pattern regarding power consumption in the house 10, the time-series pattern is within one week It is good to consider the day of the week. That is, it is preferable to consider that the patterns of power consumption are different between the holiday and the rest.

  -The time-series pattern regarding the power consumption in the house 10 may not be that of all day (24 hours), but may be a time-series pattern of a predetermined time zone. For example, the power burden amount of the vehicle 30 is set using a time-series pattern of power consumption in a time zone (for example, 7 pm to 7 am time zone) in which it is assumed that the vehicle 30 is not out. May be

  When the battery SOC is acquired from the vehicle 30 at the destination, if the vehicle position is separated from the house 10 by a predetermined distance or more (for example, 100 km or more), the setting of the power burden of the vehicle 30 based on the battery SOC You may not do this. In this case, when the vehicle 30 is far from the house 10, it becomes difficult to predict the battery SOC when the vehicle 30 returns to the house 10. That point is taken into consideration.
