[0018] [Figure 1] This figure shows an example of the overall configuration of the power management system 1 according to the first embodiment of the present invention. [Figure 2] This figure shows an example of a mobile body 50 according to the first embodiment of the present invention. [Figure 3] This figure shows an example of a transporter 40 according to the first embodiment of the present invention. [Figure 4] This is a sequence diagram illustrating an example of the operation of the power management system 1 according to the first embodiment of the present invention. [Figure 5] This figure shows an example of the overall configuration of the power management system 1 according to the second embodiment of the present invention. [Figure 6] This is a sequence diagram illustrating an example of the operation of the power management system 1 according to the second embodiment of the present invention. [Modes for carrying out the invention]

[0019] [First Embodiment] Hereinafter, referring to FIGS. 1 to 4, the power management system 1 according to the first embodiment of the present invention will be described. Hereinafter, in the directions in this embodiment, the upper, lower, left, right, front, and rear directions correspond to the up, down, left, right, front, and rear directions of the arrows appropriately shown in each drawing.

[0020] The power management system 1 according to this embodiment manages at least one of a plurality of carriers 52A / 52B having a storage battery and a plurality of traveling bodies 51A / 51B that can carry the carriers 52A / 52B and are operated by electric power.

[0021] As shown in FIG. 1, the power management system 1 includes a server 10, a first terminal 30A operated by a first user, a traveling body 51A and a carrier 52A used by the first user, a second terminal 30B operated by a second user, a traveling body 51B and a carrier 52B used by the second user, and a transporter 40.

[0022] <Moving body 50> As shown in FIG. 2, the moving body 50 according to the first embodiment of the present invention includes a traveling body 51 and a carrier 52. In this embodiment, the traveling body 51 and the carrier 52 have a storage battery.

[0023] The traveling body 51 can travel in a first direction. Here, the "first direction" is any one of the front-rear, left-right, front-oblique left-front-oblique right, and rear-oblique left-rear-oblique right directions and corresponds to the horizontal direction. The oblique angles of the front-oblique left-front-oblique right and rear-oblique left-rear-oblique right are arbitrary, respectively.

[0024] Also, the "first direction" also corresponds to a direction parallel to the traveling surface. That is, the traveling body 51 can travel in all directions along the traveling surface.

[0025] The traveling body 51 has a mounting surface 511 that faces a second direction which is upward relative to the first direction. The mounting surface 511 is included in the upper surface of the traveling body 51. Here, the "second direction" corresponds to upward. The "second direction" also corresponds to the vertical direction away from the traveling surface.

[0026] Furthermore, a third direction opposite to the second direction is also defined. Here, the "third direction" corresponds to downward and also corresponds to the vertical direction close to the running surface. Additionally, a fourth direction perpendicular to both the first and second directions is defined. Here, the "fourth direction" corresponds to the horizontal direction and also corresponds to the direction parallel to the running surface. For example, if the first direction is forward, the fourth direction will be left or right.

[0027] Furthermore, the mounting body 52 is configured to be detachable from the mounting surface 511 of the traveling body 51. When the mounting body 52 is detached (see, for example, Figure 2), first, the bottom surface of the mounting body 52, which faces the third direction, is brought into contact with the mounting surface 511, which faces the second direction. Then, by bringing both sides relatively close together, the mounting body 52 can be attached to the mounting surface 511.

[0028] More specifically, if the mounting body 52 is positioned above the mounting surface 511, the vehicle 51 is driven to the mounting position of the mounting body 52 so that both sides face each other. Then, with both sides facing each other, the mounting body 52 may be moved in a third direction to achieve mounting. If the mounting body 52 is mounted on the mounting surface 511 and mounted on the vehicle 51, it moves integrally with the vehicle 51.

[0029] On the other hand, while the mounting body 52 is attached, the mounting body 52 can be detached from the mounting surface 511 by relatively separating the lower surface of the mounting body 52 from the mounting surface 511.

[0030] More specifically, with both sides facing each other, the mounted body 52 is moved from the traveling body 51 in a second direction. Then, the mounted body 52 is positioned above the mounting surface 511, and the traveling body 51 is driven from the position where the mounted body 52 is positioned, thereby achieving detachment. When the mounted body 52 has detached from the mounting surface 511 and is not mounted on the traveling body 51, it is positioned separately from the traveling body 51.

[0031] The mounting unit 52 attached to the vehicle 51 is a so-called attachment, and the same unit may be attached and detached. Alternatively, after detaching one type of mounting unit 52, a different type of mounting unit 52 may be attached. In other words, multiple types of different mounting units 52 may be attached to a single type of vehicle 51, depending on the situation. When attached to the vehicle 51, the mounting unit 52 may be configured to perform various tasks such as farming, construction, and transportation, or it may be configured to be a rideable mobility device; the configuration is arbitrary. For example, if the configuration of the mounting unit 52 is adapted for farming, it may be configured to perform tasks such as mowing, sowing, spraying, and ridging.

[0032] <Conveyor 40> The transporter 40 is configured to deliver at least one of the traveling body 51 and the mounted body 52 that constitute the mobile body 50 to the first user.

[0033] As shown in Figure 3, the transporter 40 may be any mobile body capable of transporting the load 300, such as a four-wheeled vehicle. If the transporter 40 is a four-wheeled vehicle, it is preferable that the transporter 40 has a body that extends in the direction of travel (vehicle length direction), and that multiple vehicles 200 can enter along the vehicle length direction and that the load 300 can be positioned therein. The transporter 40 may also be called a transport vehicle or a carrier.

[0034] More specifically, as shown in Figure 3, the transporter 40 comprises a floor section 41, a traveling device 42, a storage section 43, an opening 44, a door section 45, a mounting area 46, and a placement section 47. As indicated by the arrows in Figure 4, the front and rear sides of the mobile body 50, which are the forward and reverse directions, correspond to the left and right sides of the transporter 40, which are the vehicle width direction, respectively, and the left and right sides of the mobile body 50, which are the vehicle width direction, correspond to the forward and backward directions of the transporter 40, respectively.

[0035] The floor section 41 is configured in a rectangular shape that extends in the longitudinal direction of the transport body 40. The running gear 42 is equipped with front wheels 42F and rear wheels 42R that make contact with the running surface. The floor section 41 is positioned between the front wheels 42F and the rear wheels 42R. The floor section 41 is supported by the running gear 42 and is spaced apart so as to be substantially parallel to the running surface. The floor section 41 is positioned so that the running gear 52 of the mobile body 50 can drive onto its upper side.

[0036] The storage section 43 is a roughly rectangular parallelepiped housing that extends in the vehicle length direction of the transporter 40. The storage section 43 is configured to cover the floor section 41 and the placement section 47, respectively. When a load 52 is placed in the placement section 47, the load 52 is stored inside the storage section 43. When the direction of travel of the transporter 40 is the vehicle length direction, an opening 44 is provided only at one end of the storage section 43 in the vehicle width direction.

[0037] The opening 44 connects the inside and outside of the storage section 43. When the traveling body 51 enters the loading area 46 on the floor section 41, it passes through the opening 44. The traveling body 51 also passes through the opening 44 when the loading unit 52 is loaded in the loading area 46 and it starts moving. The opening 44 is provided with a door section 45.

[0038] The door section 45 is configured to switch between a state of communication and a state of shielding the opening 44. The door section 45 maintains the shielding state when transporting the load 52 placed in the arrangement section 47. The door section 45 may be configured, for example, in the shape of a rectangular plate, with its lower end connected to the floor section 41. In this case, the door section 45 switches between a state of communication and a state of shielding the opening 44 by operating in a flap-like manner. Furthermore, when the opening 44 is in the state of communication, the door section 45 is configured to act as a ramp that guides the vehicle 51 from the outside to the loading area 46 on the floor section 41.

[0039] The mounting area 46 is located above the floor 41 inside the storage section 43, and is used to attach the load unit 52 to the vehicle 51 that has entered the floor 41. The placement section 47 is located above the floor 41 and is capable of arranging the load unit 52 to be attached to the vehicle 51. When the load unit 52 is placed in the placement section 47, the mounting area 46 attaches the load unit 52 to the vehicle 51 located below the placement section 47.

[0040] Multiple mounting areas 46 are provided on the floor 41, and one arrangement area 47, opening 44, and door 45 is provided for each of the multiple mounting areas 46. In this embodiment, four mounting areas 46 may be provided and arranged in a line along the vehicle length direction of the transport body 40. Furthermore, the number of mounting areas 46 for one transport body 40 is not limited to four, but may be any number.

[0041] In addition, the storage unit 43 may store both the mounted unit 52 and the mobile unit 51 (i.e., the mobile unit 50) at the same time, or it may store only the mobile unit 51 or only the mounted unit 52.

[0042] <Server 10> As shown in Figure 4, the server 10 includes a reception unit 11, a decision unit 12, and a notification unit 13.

[0043] The reception unit 11 receives the target vehicle from among the multiple vehicle units 51A / 51B that is to be supplied with power. In this embodiment, vehicle unit 51A is assumed to be the target vehicle.

[0044] Specifically, the reception unit 11 receives a power supply request from the first terminal 30A that includes identification information of the target vehicle, vehicle 51A, and accepts the target vehicle.

[0045] The determination unit 12 determines a vehicle from among the multiple vehicles 51A / 51B that is different from the target vehicle 51A, or a movable vehicle from among the multiple vehicles 51A / 51B that can be moved. Hereinafter, in this embodiment, vehicle 51B is assumed to be another vehicle, and vehicle 52B is assumed to be a movable vehicle.

[0046] Specifically, the determination unit 12 determines another vehicle 51B or mobile mount 52B in response to the power supply request described above. For example, the determination unit 12 may select a vehicle or mount located within a predetermined range from the current position of the target vehicle 51A as the other vehicle 51B or mobile mount 52B. Alternatively, the determination unit 12 may select a vehicle or mount located within a predetermined range from the current position of the target vehicle 51A and having a remaining battery charge of a predetermined amount or more as the other vehicle 51B or mobile mount 52B.

[0047] The notification unit 13 notifies the target vehicle 51A that it will share (supply) power from another vehicle 51B or mobile mounted unit 52B.

[0048] Specifically, the notification unit 13 may send the above-mentioned notification to the first terminal 30A of the first user using the target vehicle 51A.

[0049] Alternatively, the notification unit 13 may make the above-mentioned notification to other vehicles 51B or mobile mounts 52B.

[0050] Here, the other vehicles 51B and mobile mounts 52B may move to the location where the target vehicle 51A is located, in accordance with the notification mentioned above.

[0051] Furthermore, the notification unit 13 may also provide the above-mentioned notification to a transporter 40 that can transport other traveling bodies 51B or mobile carrying bodies 52B.

[0052] Here, the transporter 40 may move to the location where the target vehicle 51A, another vehicle 51B, or mobile mount 52B is located, in response to the notification mentioned above.

[0053] When the transporter 40 moves to the location where the target vehicle 51A is located, it transports the target vehicle 51A to the location where another vehicle 51B or mobile mount 52B is located, and at that destination, the other vehicle 51B or mobile mount 52B supplies power to the target vehicle 51A. After that, the transporter 40 may transport the target vehicle 51A to a location specified by the first user.

[0054] On the other hand, if the transporter 40 moves to a location where another vehicle 51B or mobile mount 52B is located, it transports the other vehicle 51B or mobile mount 52B to the location where the target vehicle 51A is located, and at that destination, the other vehicle 51B or mobile mount 52B supplies power to the target vehicle 51A. After that, the transporter 40 may transport the other vehicle 51B or mobile mount 52B back to its original location.

[0055] The notification unit 13 may also notify the amount of power supplied when the power of another vehicle 51B or mobile mounted unit 52B is shared (supplied) to the target vehicle 51A.

[0056] In other words, the notification unit 13 can notify other vehicles 51B or mobile mounting units 52B or the second terminal 30B of the amount of power that should be supplied from the other vehicles 51B or mobile mounting units 52B to the target vehicle 51A.

[0057] An example of the operation of the power management system 1 according to this embodiment will be described below with reference to Figure 4.

[0058] As shown in Figure 4, in step S1001, the first user uses the first terminal 30A to send a power supply request to the server 10, which includes identification information of the target vehicle 51A that the user wishes to power.

[0059] In step S1002, the determination unit 12 of the server 10 determines the other vehicle 51B or mobile mount 52B in response to the power supply request received by the reception unit 11 of the server 10.

[0060] In step S1003, the notification unit 13 of the server 10 notifies the target vehicle 51A that it will share (supply) the power of the other vehicle 51B or the mobile mount 52B to the target vehicle 51A, and in step S1004, it notifies the other vehicle 51B or mobile mount 52B that it will share (supply) the power of the other vehicle 51B or the mobile mount 52B to the target vehicle 51A.

[0061] In response to such notification, the other vehicle 51B or mobile mount 52B either moves under its own power to the location where the target vehicle 51A is located, or is transported to the location where the target vehicle 51A is located by the transporter 40, and in step S1005, supplies power to the target vehicle 51A.

[0062] In step S1006, the other vehicle 51B or mobile mount 52B notifies the server 10 of the amount of power supplied to the target vehicle 51A, and in step S1007, the target vehicle 51A notifies the server 10 of the amount of power supplied from the other vehicle 51B or mobile mount 52B.

[0063] In step S1008, the notification unit 13 of the server 10 transmits billing data to the first terminal 30A, which includes charges calculated based on the amount of power supplied from other vehicles 51B or mobile mounting units 52B and the amount of power supplied from the target vehicle 51A. [Second Embodiment] Hereinafter, with reference to Figures 5 and 6, the power management system 1 according to the second embodiment of the present invention will be described, focusing on the differences from the power management system 1 according to the first embodiment described above.

[0064] The power management system 1 according to this embodiment manages the power of multiple work vehicles 60A / 60B that are powered by electricity.

[0065] As shown in Figure 5, the power management system 1 according to this embodiment includes a server 10, a first terminal 30A operated by a first user, a second terminal 30B operated by a second user, a first work vehicle 60A, and a second work vehicle 60B.

[0066] Here, at least one of the multiple work vehicles 60A / 60B includes a mounting unit 52, a vehicle 51 on which the mounting unit 52 can be attached, and a storage battery mounted on at least one of the mounting unit 52 and the vehicle 51.

[0067] In this embodiment, as shown in Figure 5, the first work vehicle 60A includes a mounting body 52A, a traveling body 51A to which the mounting body 52A can be attached, and a storage battery mounted on at least one of the mounting body 52A and the traveling body 51A, and the second work vehicle 60B includes a storage battery mounted on the traveling body 51B and does not have a mounting body. However, the present invention is not limited to this case and is applicable to any case in which at least one of the multiple work vehicles 60A / 60B includes a mounting body 52, a traveling body 51 to which the mounting body 52 can be attached, and a storage battery mounted on at least one of the mounting body 52 and the traveling body 51.

[0068] As shown in Figure 5, the server 10 according to this embodiment includes a storage unit 20, a first receiving unit 21, a second receiving unit 22, and a notification unit 23.

[0069] The memory unit 20 manages the remaining battery capacity of multiple work vehicles 60A / 60B registered in the power management system 1.

[0070] The first reception unit 21 receives power supply vehicles, which are among the multiple work vehicles 60A / 60B that are capable of supplying electricity.

[0071] For example, the first reception unit 21 refers to the memory unit 20 and accepts, as a power supply vehicle, a work vehicle from among multiple work vehicles 60A / 60B whose remaining battery charge is equal to or greater than a predetermined amount.

[0072] The second reception section 22 accepts charging vehicles, which are work vehicles capable of receiving power supply from among the multiple work vehicles 60A / 60B.

[0073] For example, the second reception unit 22 refers to the memory unit 20 and accepts, as charging vehicles, work vehicles from among the multiple work vehicles 60A / 60B whose remaining battery charge is below a predetermined amount.

[0074] Alternatively, the second reception unit 21 may accept a work vehicle designated by a power supply request transmitted from the first user or the second user via the first terminal 30A or the second terminal 30B as a charging vehicle.

[0075] For example, the first reception unit 21 may accept the first work vehicle 60A as a power supply vehicle if the remaining charge of the first work vehicle 60A's battery is equal to or greater than a predetermined amount, and the second reception unit 22 may accept the second work vehicle 60B as a charging vehicle if the remaining charge of the second work vehicle 60B's battery is less than or equal to a predetermined amount.

[0076] Alternatively, the first reception unit 21 may accept the second work vehicle 60B as a power supply vehicle if the remaining charge of the second work vehicle 60B's battery is equal to or greater than a predetermined amount, and the second reception unit 22 may accept the first work vehicle 60A as a charging vehicle if the remaining charge of the first work vehicle 60A's battery is less than or equal to a predetermined amount.

[0077] The notification unit 23 notifies the charging vehicle that it will share (supply) power from the power supply vehicle.

[0078] For example, if the first work vehicle 60A is a power supply vehicle and the second work vehicle 60B is a charging vehicle, the notification unit 23 may make the above-mentioned notification to the first work vehicle 60A or to the first terminal 30A of the first user using the first work vehicle 60A. In such a case, the notification unit 23 may also make the above-mentioned notification to the second work vehicle 60B or to the second terminal 30B of the second user using the second work vehicle 60B. Here, the first work vehicle 60A may move to the location where the second work vehicle 60B is located in response to the above-mentioned notification, or the second work vehicle 60B may move to the location where the first work vehicle 60A is located in response to the above-mentioned notification.

[0079] For example, if the second work vehicle 60B is a power supply vehicle and the first work vehicle 60A is a charging vehicle, the notification unit 23 may make the above-mentioned notification to the second work vehicle 60B or to the second terminal 30B of the second user using the second work vehicle 60B. In such a case, the notification unit 23 may also make the above-mentioned notification to the first work vehicle 60A or to the first terminal 30A of the first user using the first work vehicle 60A. Here, the second work vehicle 60B may move to the location where the first work vehicle 60A is located in response to the above-mentioned notification, or the first work vehicle 60A may move to the location where the second work vehicle 60B is located in response to the above-mentioned notification.

[0080] Furthermore, the notification unit 23 may also provide the above-mentioned notification to the transporter 40, which is capable of transporting the first work vehicle 60A or the second work vehicle 60B.

[0081] In this case, the transporter 40 may move to the location where the power supply vehicle or charging vehicle is located, in accordance with the notification mentioned above.

[0082] When the transporter 40 moves to the location where the power supply vehicle is located, it transports the power supply vehicle to the location where the charging vehicle is located, and power supply work is performed at the destination. After that, the transporter 40 may transport the power supply vehicle to a designated location.

[0083] On the other hand, if the transporter 40 moves to the location where the charging vehicle is located, it transports the charging vehicle to the location where the power supply vehicle is located, and power supply work is performed at the destination. After that, the transporter 40 may transport the charging vehicle to a designated location.

[0084] The notification unit 23 may also notify the amount of power supplied when the power supply vehicle shares (supplies power) to the charging vehicle.

[0085] In other words, the notification unit 23 can notify the power supply vehicle or the terminal of the user using the power supply vehicle about the amount of power that should be supplied from the power supply vehicle to the charging vehicle.

[0086] An example of the operation of the power management system 1 according to this embodiment will be described below with reference to Figure 6.

[0087] As shown in Figure 6, in step S2001, the first reception unit 21 of the server 10 refers to the storage unit 20 to determine the power supply vehicle, and the second reception unit 22 of the server 10 refers to the storage unit 20 to determine the charging vehicle.
