  By the way, in a situation where the vehicle is out, the house side system and the vehicle side system are not electrically connected. In such a state, regarding the house side system and the vehicle side system as a comprehensive system, regarding the efficient use of the electric power stored on the house side and the electric power stored on the vehicle side in total It has not been studied in the past.

  The present invention has been made in view of these problems, and in a situation where power cannot be directly exchanged between the house-side system and the vehicle-side system, the power stored on the house side and the power stored on the vehicle side are stored. The purpose is to make it possible to use the electric power in total and efficiently.

In the storage amount management system of the present invention that achieves the above object, the house is provided with the house-side storage means, and the vehicle is provided with the vehicle-side storage means. Then, in a situation where the processing means cannot directly exchange power between the housing-side power storage means and the vehicle-side power storage means, information on the power storage amount of each power storage means is obtained, and the power storage amount of one of the power storage means Is determined to be insufficient, a process for supplying the power stored in the other power storage unit to the power storage unit is performed.

  According to such an electricity storage amount management system, even in a situation where electric power cannot be directly exchanged between the house-side electricity storage means and the vehicle-side electricity storage means, the other electricity storage means is used to supplement the electricity storage amount of one electricity storage means. It is possible to perform processing for effectively using the power stored in the means. Therefore, the electric power stored on the house side and the electric power stored on the vehicle side can be used efficiently in total.

  By the way, in a state where the storage amount of one of the housing-side power storage means and the vehicle-side power storage means is insufficient, the power stored in the other power storage means is supplied to the power storage means. However, it is also assumed that charging from other charging means is advantageous in terms of cost.

Therefore, processing means, even when the charged amount of one of the storage means of the housing-side power storage device and the vehicle-side storage means is determined to be insufficient, power stored in the other storage means when the cost of is determined to be lower than the cost of charging the other of the charging means, the process may me a line for supplying the power stored in the other storage means. According to such a storage amount management system, when the cost when charging from other charging means is lower, charging from the charging means reduces the cost required to recover the storage amount. It becomes possible to do.

Here, the cost of electric power charge reservoir may be calculated by integrating the power cost during charging. According to such a storage amount management system, it is possible to calculate more accurately than in the case where the cost of stored power is set to a fixed value or the like. Therefore, it is possible to properly compare the cost of the electric power stored in the power storage means and the cost when charging from another charging means.

According to such a storage amount management system, low-cost electric power (regenerative electric power) generated by the rotational force of the wheels during deceleration can be effectively used.

On the other hand, processing means, in a case where the storage amount of the vehicle-side power storage device is determined to be insufficient, the cost of electric power stored in the residential side accumulator unit, the surrounding area of the current location or travel route of the vehicle to when it is determined to be lower than the cost in the case of charging the lowest-cost charging station exists, the process for supplying power stored in the housing side storage means may it line. According to such a storage amount management system, compared with the case where the cost when charging from the charging stand is a fixed value or the like, the cost of the power stored in the housing-side storage means and the cost when charging from the charging stand And can be compared appropriately.

Moreover, processing unit, when the storage amount of the housing-side storage means is determined to be insufficient, as a process for supplying power stored in the vehicle-side power storage unit with respect to housing side battery unit, the vehicle the process of increasing the storage amount of the side storage means may it line. According to such a power storage amount management system, it is possible to increase the power that can be supplied to the house-side power storage means, compared to the case where the power storage amount of the vehicle-side power storage means is not increased.

Specifically, processing means, as a process for increasing the storage amount of the vehicle-side storage means, the processing to increase the upper limit of the charged amount of the vehicle-side storage means may I line. According to such a power storage amount management system, it is possible to increase the power that can be supplied to the house-side power storage means, compared to a state where the upper limit value of the power storage amount of the vehicle-side power storage means is regulated.

Moreover, processing unit, when the storage amount of the housing-side storage means is determined to be insufficient, as a process for supplying power stored in the vehicle-side power storage unit with respect to housing side battery unit, the vehicle the charge control of the vehicle-side storage means may me line to the power to be supplied to the housing side battery means is secured at the time but which arrives in the housing. According to such a power storage amount management system, it is possible to supply a necessary amount of power to the housing-side power storage means at the time when the vehicle arrives at the house, while preventing excess power from being stored.

By the way, even in a situation where electric power cannot be directly exchanged between the house-side power storage means and the vehicle-side power storage means, it is possible to exchange indirectly.
That is, in a situation which can not be exchanged power directly between the residential side battery unit and a vehicle-side storage means, further comprising a mediating means for implementing the exchanges of indirect power to mediate these, processing means When it is determined that the power storage amount of any one of the housing-side power storage means and the vehicle-side power storage means is insufficient, the power stored in the other power storage means is supplied to the mediation means treatment may be I the line for. According to such a storage amount management system, it is possible to supply power indirectly even in a situation where the vehicle is located away from the house.

Specifically, the mediation unit includes a charging station, the processing means, when it is determined that the storage amount of the housing-side storage means is insufficient, the peripheral area of the current location or travel route of the vehicle Information on the charging station existing in the vehicle may be displayed to the driver.

[2. processing]
Next, processing executed in the storage amount management system of this embodiment will be described. In addition, the process demonstrated below presupposes the condition which has gone out by the vehicle. That is, in the situation where the vehicle is parked in the house, the house side system 10 and the vehicle side system 20 can be electrically connected by a cable or the like, and the house side power storage device 11 and the vehicle side power storage device 21 It is possible to exchange power directly between the two. On the other hand, since the house side system 10 and the vehicle side system 20 cannot be electrically connected by a cable or the like in a situation where the vehicle is out, the housing side power storage device 11 and the vehicle side power storage device 21 Power cannot be exchanged directly between them.

  First, in the situation where the house-side power storage device 11 of the house-side system 10 is overcharged and the vehicle-side power storage device 21 of the vehicle-side system 20 is insufficient in power storage amount, the flow of processing executed by the power storage amount management system of the present embodiment. Will be described with reference to the flowchart of FIG.

  In the vehicle-side system 20, the navigation control unit 34 of the navigation device 30 calculates the amount of power required for the vehicle to travel from the current location to the destination based on the planned travel route to the destination (S101). Moreover, the navigation control part 34 acquires the information of the electrical storage amount of the vehicle side electrical storage apparatus 21 from the vehicle side control apparatus 25 (S102).

  Then, the navigation control unit 34 compares the calculated amount of power (the amount of power required to travel to the destination) with the amount of power stored in the vehicle-side power storage device 21 and the amount of stored power is less than the calculated amount of power. Is determined to be insufficient (S103). In this case, the navigation control unit 34 transmits information on the insufficient power amount as a charging status notification from the BT communication unit 33 to the mobile phone device 40 (S104). Note that the charging status notification includes the communication address of the 3G communication device 15 provided in the house where the user of the vehicle resides.

  When receiving the charging status notification from the navigation device 30, the cellular phone device 40 transfers the charging status notification with the communication address of the 3G communication device 15 included in the charging status notification as the transmission destination (S105). Thereby, the charging status notification is transmitted from the navigation device 30 to the 3G communication device 15.

  On the other hand, in the house-side system 10, when the 3G communication device 15 receives the charge status notification from the mobile phone device 40 (S106), the information on the insufficient power amount included in the charge status notification is sent to the house-side control device 16. Output. When the information on the amount of insufficient power is input from the 3G communication device 15, the house side control device 16 calculates the cost of supplied power when supplying this amount of insufficient power from the house side to the vehicle side (S 107).

  When power is supplied from the house side to the vehicle side, first, the power stored in the house side power storage device 11 is supplied. For this reason, when the house-side power storage device 11 is charged with power, the house-side control device 16 calculates the cost of power stored in the house-side power storage device 11 by accumulating the power cost at the time of charging. Processing is to be performed. Specifically, since the electric power generated by the electric power generation device 12 and the electric power supplied from the electric power company 50 are charged in the electric power storage device 11 in the house, the cost of each electric power is integrated. Then, the cost of stored power is calculated. For example, the power (purchased power) supplied from the electric power company 50 is calculated from the actual cost (electricity fee determined in advance according to the usage time zone, etc.) to calculate the cost, and is generated by the residential power generator 12. The purchased power is lower than the purchased power (for example, 0). By doing in this way, the cost of the electric power stored in the house side power storage device 11 can be determined.

  However, if the amount of power that can be supplied from the housing-side power storage device 11 is less than the amount of power shortage on the vehicle side, it is necessary to supply power from other than the housing-side power storage device 11, so the cost is also predicted. To calculate. For example, about the house side power generation device 12, since it can supply electric power only in the condition where solar energy is obtained, it is possible to predict the amount of electric power that can be generated based on the time zone.

  When the housing-side control device 16 calculates the supply power cost when supplying the vehicle-side insufficient power amount from the housing side, the calculated supply power cost is transmitted from the 3G communication device 15 to the mobile phone device 40 as a charging status response. (S108). Note that the charging status response includes the communication address of the BT communication unit 33 provided in the vehicle used by the user who lives in the house.

  When receiving the charging status response from the 3G communication device 15, the cellular phone device 40 transfers the charging status response with the communication address of the BT communication unit 33 included in the charging status response as the transmission destination (S109). Thereby, the charging status response is transmitted from the 3G communication device 15 to the navigation device 30.

  When the navigation control unit 34 of the navigation device 30 receives the charging status response via the BT communication unit 33 (S110), the navigation control unit 34 selects a charging method for compensating for the insufficient power amount (S111). Specifically, the cost of supply power when receiving power supply from the house side is compared with the cost of supply power when receiving power supply from the charging stand 60, and the one with the lower cost is selected.

  Here, the cost of supplied power in the case of receiving power supply from the charging station 60 is the charging station 60 existing in the peripheral area (area within a predetermined distance from each point on the route) of the planned travel route to the destination. The lowest power supply cost is adopted. Information such as the position of the charging station 60 and the cost of supplied power uses navigation information (map data). Further, instead of the surrounding area of the planned travel route, for example, a surrounding area of the current location (an area within a predetermined distance range from the current location) may be used.

  Then, the navigation control unit 34 transmits information on the selected charging method (house or charging station 60) as a selection result notification to the house side system 10 via the mobile phone device 40 (S112). Note that the communication result of the 3G communication device 15 is included in the selection result notification.

  When the navigation control unit 34 selects to receive power supply from the charging station 60 (S113: charging station), the target charging station 60 (charging station 60 with the lowest cost of supplied power) is displayed on the display device. While displaying on the map of (the apparatus which arrange | positioned the display screen in the position which a driver | operator can visually recognize), the minimum electric energy (insufficient electric energy) which should be charged there is also displayed (S114).

  On the other hand, when the navigation control unit 34 has selected to receive power supply from the house side (S113: house), the arbitrary charge stand 60 performs processing for receiving power supply from the house side. . That is, while going out in a vehicle, the house side power storage device 11 and the vehicle side power storage device 21 are not electrically connected, and power is directly exchanged between the house side power storage device 11 and the vehicle side power storage device 21. Therefore, power is indirectly supplied through an arbitrary charging station 60.

  Specifically, the navigation control unit 34 displays the cost merit obtained by receiving power supply from the house via the charging station 60 and the minimum necessary amount of power to be charged for traveling to the destination. In addition to displaying on the device, information on the charging station 60 existing in the surrounding area of the planned travel route (or the surrounding area of the current location) is also displayed to allow the driver to charge at any charging station 60 (S115). . Thereafter, the navigation control unit 34 uses the information on the charging station 60 (company name and the like) and the information on the amount of power charged there (power supply amount, unit price, etc.) as a charging result notification via the mobile phone device 40. (S116). The charge result notification includes the communication address of the 3G communication device 15.

  In the house side system 10, when this charge result notification is received (S117), the power supplied by the vehicle is supplied to the electric power company 50, and information on the charging station 60 is transmitted to the electric power company 50. Power is supplied to the charging station 60 through 50. That is, the amount of power supplied from the charging station 60 to the vehicle is supplied from the house to the charging station 60. Therefore, payment to the charging stand 60 from the vehicle side becomes unnecessary. Note that a fee according to the agreement may be paid to the charging stand 60. For example, in addition to the amount of power supplied from the charging stand 60 to the vehicle, the amount of power for the fee is supplied from the house to the power company 50 (and eventually). You may make it supply to the charging stand 60).

  Next, in a situation where the house-side power storage device 11 of the house-side system 10 is short of the amount of power storage and the vehicle-side power storage device 21 of the vehicle-side system 20 is overcharged, the processing executed by the power storage amount management system of the present embodiment A flow is demonstrated using the flowchart of FIG.

  In the house-side system 10, the house-side control device 16 acquires information on the amount of electricity stored in the house-side power storage device 11 (S201). Then, the house-side control device 16 has a shortage of charge when the charge amount of the house-side power storage device 11 is equal to or less than a predetermined charge amount determination threshold value (for example, a value corresponding to 40% of full charge). (S202). In this case, the house-side control device 16 transmits information on the amount of insufficient power as a charging status notification from the 3G communication device 15 to the mobile phone device 40 (S203). Note that the charging status notification includes the communication address of the BT communication unit 33 provided in the vehicle used by the user who lives in the house.

  When receiving the charging status notification from the 3G communication device 15, the cellular phone device 40 transfers the charging status notification with the communication address of the BT communication unit 33 included in the charging status notification as the transmission destination (S204). Thereby, the charging status notification is transmitted from the 3G communication device 15 to the navigation device 30.

  On the other hand, in the vehicle-side system 20, when the BT communication unit 33 receives the charging status notification from the mobile phone device 40 (S205), the navigation control unit 34 receives the information on the insufficient power amount included in the charging status notification. To the vehicle-side control device 25. When the information on the insufficient power amount is input from the navigation control unit 34, the vehicle-side control device 25 calculates the cost of the supplied power when the insufficient power amount is supplied from the vehicle side to the house side (S206).

  When power is supplied from the vehicle side to the house side, the power stored in the vehicle side power storage device 21 is supplied. For this reason, when the vehicle-side power storage device 21 is charged with power, the vehicle-side control device 25 calculates the cost of the power stored in the vehicle-side power storage device 21 by accumulating the power cost at the time of charging. Processing is to be performed.

  Specifically, the vehicle-side power storage device 21 is charged with the electric power generated by the rotational force of the engine and the regenerative electric power generated when the vehicle is decelerated. Therefore, by accumulating the cost of each electric power, Calculate the cost of stored power. For example, the power generated by the rotational force of the engine is calculated from the actual cost of the fuel used in the engine, and the cost is calculated for the regenerative power lower than the power generated by the engine (for example, 0). By doing in this way, the cost of the electric power stored in the vehicle-side power storage device 21 can be determined. The actual cost of fuel may be a fixed value, or the price at the time of refueling may be stored manually or automatically. In the case of automatic storage, it may be automatically acquired when the fuel remaining amount is increased by using fuel lid open as a trigger.

  Here, if the vehicle is heading toward a house (on the way home), it is possible to supply the electric power stored in the vehicle-side power storage device 21 when the vehicle returns home. In this case, even if the amount of power that can be supplied from the vehicle-side power storage device 21 is less than the shortage power amount on the house side, the amount of power stored in the vehicle-side power storage device 21 can be increased before reaching the house. The cost for that amount is also calculated. For example, the amount of charge for regenerative power increases as the number of downhills increases. Therefore, it is possible to predict regenerative power based on the height difference in the planned travel route to the house.

  On the other hand, if the vehicle is not heading to the house (on the way home), it is necessary to supply power to the house through the charging stand 60 as in the process of FIG. The fee is paid to the charging station 60.

  When the vehicle-side control device 25 calculates the supply power cost when supplying the deficient amount of electricity on the house side from the vehicle, the vehicle-side control device 25 transmits the calculated supply power cost from the BT communication unit 33 to the mobile phone device 40 as a charge status response. (S207). The charging status response includes the communication address of the 3G communication device 15 provided in the house where the vehicle user resides.

  When receiving the charging status response from the navigation device 30, the cellular phone device 40 transfers the charging status response with the communication address of the 3G communication device 15 included in the charging status response as the transmission destination (S208). Thereby, a charging status response is transmitted from the navigation device 30 to the 3G communication device 15.

  When the house-side control device 16 of the house-side system 10 receives the charge status response via the 3G communication device 15 (S209), the house-side control device 16 selects a charge method for compensating for the insufficient power amount (S210). Specifically, the cost of power supplied when receiving power from the vehicle is compared with the cost of power purchased from the power company 50, and the one with the lower cost is selected.

  And the navigation control part 34 transmits the information of the selected charging method (vehicle or purchase) to the vehicle side system 20 via the mobile telephone apparatus 40 as a selection result notification (S211). The selection result notification includes the communication address of the BT communication unit 33.

  When the house-side control device 16 selects to purchase electric power from the electric power company 50 (S212: purchase), the shortage electric power is covered by the purchased electric power (S213). On the other hand, when it is selected that the supply of power from the vehicle is selected (S212: vehicle), when the amount of power expected to be supplied from the vehicle is less than the shortage of power, the shortage is covered by the purchased power. (S214).

  When the vehicle-side control device 25 receives a selection result notification to receive power supply from the vehicle (S215), if the vehicle is heading to a house (on the way home) (S216: YES), when returning home Charging control is performed so that electric power corresponding to the amount of insufficient electric power on the house side is stored in the vehicle-side power storage device 21 (S217). In this case, a process of changing the upper limit value of the power storage amount of the vehicle-side power storage device 21 as necessary (increasing the upper limit value) is performed. In particular, when the amount of power shortage on the house side is greater than or equal to the power storage capacity of the vehicle-side power storage device 21, the upper limit value of the power storage amount of the vehicle-side power storage device 21 is changed to the maximum value. Charge control is performed so that the battery is fully charged.

  On the other hand, if the vehicle is not heading to the house (on the way home) (S216: NO), the navigation control unit 34 supplies power to the house via the charging stand 60 and that the house is short of power. Is displayed on the display device, and information on the charging station 60 existing in the peripheral area of the planned travel route (or the peripheral area of the current location) is also displayed (S218).

[3. effect]
As described above, in the power storage amount management system according to the present embodiment, in a situation where power cannot be directly exchanged between the house-side power storage device 11 and the vehicle-side power storage device 21, either power storage amount is insufficient. If it is determined that the power is stored, a process for supplying the power stored in the other is performed. For this reason, even in a situation where electric power cannot be directly exchanged between the housing-side power storage device 11 and the vehicle-side power storage device 21, the housing-side system 10 and the vehicle-side system 20 are combined with a comprehensive power storage facility and power generation facility. As a result, the power stored in each can be used efficiently in total.

  Further, in this power storage amount management system, when it is determined that the power storage amount of any one of the house-side power storage device 11 and the vehicle-side power storage device 21 is insufficient, the cost of the power stored in the other When it is determined that the cost is lower than the cost in the case of charging from other charging means (for example, the electric power company 50 or the charging stand 60), a process for supplying the electric power stored in the other is performed. For this reason, when the cost when charging from other charging means is lower, charging from the charging means makes it possible to reduce the cost required to recover the amount of stored electricity.

  In this storage amount management system, the cost of stored power is calculated by integrating the power cost at the time of charging, so it is calculated more accurately than when the stored power cost is set to a fixed value or the like. can do. Therefore, it is possible to appropriately compare the cost of the stored power with the cost when charging from another charging means.

  In particular, in this storage amount management system, the power generated by solar power generation is set at a lower cost than the purchased power, and similarly, the regenerative power is set at a lower cost than the power generated by the engine. It is possible to effectively use low-cost power such as generated power and regenerated power.

  Further, in this power storage amount management system, when it is determined that the power storage amount of the vehicle-side power storage device 21 is insufficient, the cost of the power stored in the house-side power storage device 11 is determined based on the current location of the vehicle or the traveling schedule. When it is determined that the cost is lower than the cost when charging from the lowest-cost charging station 60 existing in the peripheral area of the route, a process for supplying the electric power stored in the house-side power storage device 11 is performed. For this reason, compared with the case where the cost in the case of charging from the charging stand 60 is set to a fixed value or the like, the cost of the electric power stored in the house-side power storage device 11 and the cost in the case of charging from the charging stand 60 are appropriately compared. can do.

  Further, in this power storage amount management system, when it is determined that the power storage amount of the house side power storage device 11 is insufficient, the vehicle power storage device 21 is increased by increasing the upper limit value of the power storage amount of the vehicle side power storage device 21. Increase the amount of electricity stored. For this reason, the electric power which can be supplied with respect to the house side electrical storage apparatus 11 can be increased compared with the state in which the upper limit of the electrical storage amount of the vehicle side electrical storage apparatus 21 was regulated. For example, on the house side, it is a situation where the power generation of the house side power generation device 12 cannot be expected from the weather condition in spite of the daytime (high electricity bill) time period, whereas on the vehicle side, the vehicle side In a situation where the power storage device 21 has been charged up to the upper limit of the amount of power stored (surplus) and the charging of the generated power by the engine has been discarded, the upper limit is changed to a higher value. By accumulating more cost power, the power on the vehicle side can be used efficiently.

  In addition, since charging control is performed on the vehicle-side power storage device 21 so that power to be supplied to the home-side power storage device 11 is ensured when the vehicle arrives at the home, the home-side power storage is performed when the vehicle arrives at the home. While it is possible to supply a necessary amount of power to the device 11, it is possible to prevent excess power from being accumulated.

  Further, in this power storage amount management system, since the power can be indirectly exchanged between the house-side power storage device 11 and the vehicle-side power storage device 21 via the power company 50 and the charging stand 60, the vehicle can be housed. Even in a situation located at a location away from the vehicle, it is possible to supply power indirectly. For example, while the house side is in a situation where low-cost power such as the power generated by the house-side power generation device 12 or midnight power is surplus, the amount of power stored in the vehicle-side power storage device 21 is insufficient on the vehicle side. In such a situation, the low-cost electric power of the house-side power storage device 11 is indirectly supplied to the vehicle-side power storage device 21, so that the power on the house side can be used efficiently.

  In particular, when it is determined that the amount of electricity stored in the house-side power storage device 11 is insufficient, information on the charging station 60 existing in the current location of the vehicle or the area around the planned travel route is displayed to the driver. ing. For this reason, by supplying the electric power of the vehicle-side power storage device 21 to the charging stand 60, it is possible to prompt the driver to supply the power indirectly to the house-side power storage device 11.

  In this power storage amount management system, the house side system 10 and the vehicle side system 20 exchange information by wireless communication via the mobile phone device 40. For this reason, even in a situation where the vehicle is located away from the house, it is possible to acquire information on the amount of electricity stored in each of the house-side power storage device 11 and the vehicle-side power storage device 21. And compared with the case where the facility which can communicate directly between a house and a vehicle is provided, it can comprise at low cost.
