[0011] Regarding technologies for charging objects to be powered, there have traditionally been at least the following challenges.

[0012] In some cases, dedicated charging equipment is required to supply power to the object being charged. For example, the object being charged may include a mobile device. This mobile device may include electric vehicles such as electric-assist bicycles and electric mini-mobility vehicles. Dedicated charging equipment is required to supply power to electric vehicles. Therefore, users had to find dedicated charging equipment to charge their electric vehicles while out and about. Even when using such charging equipment, users had to perform special tasks, such as removing the battery installed in the electric vehicle. Users who wanted to avoid such hassle had to constantly monitor the remaining power capacity of their electric vehicle while using it.

[0013] In addition, when the power supply target object described above is a rental item, the user cannot substantially use the rental item while it is being charged. In this case, there is a problem that the rental fee including the time during which the user cannot substantially use the rental item can be charged to the user. For example, when the user charges the rental item at home, there is also a problem that an electricity fee corresponding to the amount of electricity used to charge the rental item is charged to the user.

[0014] Based on the above preliminary explanations, embodiments are disclosed below.

[0015] (First Embodiment) FIG. 1 is a schematic diagram of a power supply system 10 according to the first embodiment.

[0016] The power supply system 10 is a system for supplying power (charging) to a power supply target object 12. The power supply target object 12 may include a moving body. The moving body may include electric vehicles such as an electric assist bicycle (hereinafter simply referred to as a bicycle) and an electric small mobility. Further, the power supply target object 12 may include a rental item that is rented to the user USR on a paid basis. In this embodiment, a case where a bicycle that can be rented to a plurality of users USR is included in the power supply target object 12 will be described as an example.

[0017] As shown in FIG. 1, the power supply system 10 includes an adapter 100, a power supply support device 200 (terminal device 14), a mobile terminal device 300, and a server device 400. The power supply support device 200 is attached to the power supply target object 12. Note that the installation position of the power supply support device 200 on the power supply target object 12 which is a bicycle is not limited to the illustration in FIG. 1 (inside the basket of the bicycle).

[0018] Furthermore, the adapter 100 and the power supply support device 200 can be connected via a connection cable 24. The connection cable 24 is a predetermined cable that serves as both a power supply cable and a communication cable. The connection cable 24 includes, but is not limited to, a USB (Universal Serial Bus) cable compatible with PD (Power Delivery).

[0019] Figure 2 is a block diagram of the adapter 100 according to the first embodiment.

[0020] As shown in Figure 2, the adapter 100 includes a first connection part 102, a second connection part 104, and a control unit 106.

[0021] The first connection section 102 includes a power plug 102a that can be connected to a standard power outlet 18 (see also Figure 1). The power outlet 18 is installed in urban areas as appropriate by its owner. The power outlet 18 is installed, for example, on the exterior wall of a building, but is not limited to this. The owner is not limited to an individual (natural person), but may also be a company, organization, etc.

[0022] The adapter 100 may be managed by the owner and connected to the power outlet 18 by the owner. The adapter 100 may be equipped with a fixing member (not shown) that prevents it from becoming disconnected from the power outlet 18. This can prevent the owner from losing the adapter 100 installed outdoors.

[0023] The second connection section 104 includes a connector 104a that can be connected to the aforementioned connection cable 24 (see also Figure 1).

[0024] The connection cable 24 is connected to the battery 20 (Figure 1) provided in the power supply target object 12 via the power supply support device 200. Therefore, the second connection part 104 can be connected to the battery 20 of the power supply target object 12 via the connection cable 24 and the power supply support device 200. The second connection part 104 is also connected to the first connection part 102. Therefore, the adapter 100 can supply power supplied from the power outlet 18 connected to the first connection part 102 to the battery 20 of the power supply target object 12 via the connection cable 24 and the power supply support device 200. A more detailed explanation of the power supply support device 200 will be given later.

[0025] The control unit 106 may include a relatively small computer such as a microcontroller. Therefore, the control unit 106 may be equipped with a processor, memory, etc. (not shown) that constitute the computer. The control unit 106 may also include an IC (Integrated Circuit) such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array).

[0026] As shown in Figure 2, the control unit 106 comprises an authentication information acquisition unit 108, an authentication unit 110, and a power supply control unit 112. The authentication information acquisition unit 108, the authentication unit 110, and the power supply control unit 112 can be realized, for example, by the processor described above executing a program stored in the memory described above. At least a part of the authentication information acquisition unit 108, the authentication unit 110, and the power supply control unit 112 may be realized by an IC such as an ASIC or FPGA described above.

[0027] The authentication information acquisition unit 108 acquires authentication information. A more detailed explanation will be given later, but the authentication information is supplied from the power supply support device 200 via the connection cable 24. The authentication information includes, for example, information for authenticating user USR, who possesses the power supply support device 200 (power supply target object 12), as a legitimate user of the adapter 100.

[0028] The adapter 100 may also be equipped with a communication module (not shown) for wireless communication such as Bluetooth®. In that case, the authentication information acquisition unit 108 may acquire authentication information from the power supply support device 200 via such wireless communication.

[0029] The authentication unit 110 performs authentication based on the authentication information acquired by the authentication information acquisition unit 108. This allows the authentication unit 110 to authenticate user USR, who possesses the power supply support device 200, as a legitimate user of the adapter 100. The authentication unit 110 performs authentication, for example, by comparing the verification information pre-stored in the memory described above with the authentication information acquired by the authentication information acquisition unit 108.

[0030] The power supply control unit 112 performs processing to control the power supply from the power outlet 18 to the power supply target object 12 via the adapter 100, based on whether or not the authentication by the authentication unit 110 has been successful.

[0031] More specifically, if authentication by the authentication unit 110 is unsuccessful, the power supply control unit 112 restricts (prohibits) the power supply from the power outlet 18 to the powered object 12 via the adapter 100. Note that when the connection cable 24 is connected to the second connection unit 104 (initial state), the power supply control unit 112 restricts the power supply.

[0032] In response to this, if authentication by the authentication unit 110 is successful, the power supply control unit 112 allows power to be supplied from the power outlet 18 to the power supply target object 12 via the adapter 100. If authentication by the authentication unit 110 is successful, the power supply control unit 112 allows the power supply until predetermined conditions (termination conditions) are met. Termination conditions may include, but are not limited to, the disconnection of the connection between the adapter 100 and the power supply support device 200 (power supply target object 12), or the power supply target object 12 being fully charged.

[0033] Figure 3 is a block diagram of the power supply support device 200 according to the first embodiment.

[0034] The power supply support device 200 is a device that acquires information indicating the amount of power supplied from the adapter 100 (supplied power amount). Furthermore, the power supply support device 200 functions as a terminal device 14, which is an authentication device that supplies the aforementioned authentication information to the adapter 100 via the authentication information supply unit 210, which will be described later. In other words, the power supply support device 200 is equipped with a terminal device 14. As shown in Figure 3, the power supply support device 200 comprises a connector 202, a communication unit 204, and a control unit 206.

[0035] Connector 202 is a connector that can be connected to the connecting cable 24 (see also Figure 1). Connector 202 and the connecting cable 24 may be detachable or may be inseparably integrated.

[0036] The communication unit 204 includes a communication module (not shown) for wireless communication. Wireless communication includes short-range wireless communication such as Bluetooth®.

[0037] The control unit 206 of the power supply support device 200 may include a relatively small computer such as a microcontroller. Therefore, the control unit 206 may be equipped with a processor, memory, etc. that constitute the computer. The control unit 206 may also include ICs such as ASICs and FPGAs.

[0038] As shown in Figure 3, the control unit 206 includes a connection determination unit 208, an authentication information supply unit 210, a usage information acquisition unit 212, and a usage information supply unit 214. The connection determination unit 208, the authentication information supply unit 210, the usage information acquisition unit 212, and the usage information supply unit 214 can be realized, for example, by having the processor provided in the control unit 206 execute a program stored in the memory provided in the control unit 206. At least a portion of the connection determination unit 208, the authentication information supply unit 210, the usage information acquisition unit 212, and the usage information supply unit 214 may be realized by the predetermined integrated circuit provided in the control unit 206.

[0039] The connection determination unit 208 determines whether the powered object 12 and the adapter 100 are connected by the connection cable 24. More specifically, the connection determination unit 208 determines whether the adapter 100 and the battery 20 are connected via the power supply support device 200 and the connection cable 24. The connection determination unit 208 determines whether the powered object 12 and the adapter 100 are connected by the connection cable 24 based on detection signals from sensors (not shown) appropriately provided on the adapter 100, power supply support device 200, connection cable 24, etc.

[0040] The authentication information supply unit 210 performs a process to output authentication information from the connector 202 of the power supply support device 200 when the connection determination unit 208 determines that the power supply target object 12 and the adapter 100 are connected by the connection cable 24. As a result, the adapter 100 performs authentication based on the authentication information, as described above. The authentication information is stored in advance, for example, in the memory provided in the control unit 206.

[0041] The usage information acquisition unit 212 acquires usage information indicating the usage status of the adapter 100 by the user USR. The usage information may include, for example, owner information and power supply amount information.

[0042] Owner information is identification information indicating the owner of the power outlet 18 (adapter 100). Owner information is stored in advance, for example, in the memory of the adapter 100 (as described above). Owner information can be supplied to the power supply support device 200 via the connection cable 24.

[0043] The power supply amount information is information indicating the amount of power supplied. The amount of power supplied is the amount of power supplied to the powered object 12 via the connecting cable 24. According to this embodiment, the amount of power supplied can be understood as the amount of power supplied from the power outlet 18 to the powered object 12 via the adapter 100. The usage information acquisition unit 212 acquires the power supply amount information based on the detection signal of a power sensor (not shown), which is a sensor for detecting the amount of power supplied, for example. The power sensor is provided on the powered object 12, but may also be provided on the adapter 100. In that case, the power supply amount information is supplied to the power supply support device 200, for example, via the connecting cable 24.

[0044] As mentioned above, the adapter 100 may be equipped with a wireless communication module. In that case, at least a portion of the usage information may be supplied from the adapter 100 to the power supply support device 200 via wireless communication.

[0045] The usage information supply unit 214 outputs (transmits) the usage information acquired by the usage information acquisition unit 212 to the mobile terminal device 300. The usage information supply unit 214 outputs the usage information to the mobile terminal device 300 via wireless communication. As described above, the adapter 100 may be equipped with a communication module (not shown). In that case, at least a portion of the usage information (owner information, power supply amount information) may be output from the adapter 100 to the mobile terminal device 300 by the communication module.

[0046] Figure 4 is a block diagram of the mobile terminal device 300 according to the first embodiment.

[0047] The mobile terminal device 300 is a communication device that can be carried by the user USR. Portable smart devices such as smartphones are included in, but are not limited to, the mobile terminal device 300. As shown in Figure 4, the mobile terminal device 300 comprises a communication unit 302, a display unit 304, an operation unit 306, a calculation unit 308, and a storage unit 310.

[0048] The communication unit 302 includes a communication module (not shown). This communication module communicates with, for example, the power supply support device 200 described above via wireless communication. The communication module also communicates with the server device 400 via a network NW (Figure 1). The network NW may include the Internet. A more detailed description of the server device 400 will be given later.

[0049] The display unit 304 includes an output display device (not shown). This output display device includes, for example, a display panel, display elements, etc., that form a display screen. The display panel is, for example, a liquid crystal panel, but is not limited thereto.

[0050] The operation unit 306 includes an input device that can be operated by the user USR. This input device includes, but is not limited to, a touch panel located on the display unit 304 along with the display panel described above.

[0051] The arithmetic unit 308 includes a processing circuitry (not shown). This processing circuitry includes, for example, one or more processors such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). This processing circuitry may also include ICs such as ASICs or FPGAs.

[0052] The storage unit 310 includes one or more memory locations. These one or more memory locations include non-volatile memory. Non-volatile memory is a recording medium that stores programs, tables, maps, etc., on a non-temporary basis. For example, ROM (Read Only Memory) and flash memory are included in non-volatile memory. The storage unit 310 (one or more memory locations) may also include volatile memory. For example, RAM (Random Access Memory) is included in volatile memory.

[0053] The arithmetic unit 308 includes an information acquisition unit 312 and an information transmission unit 314. The information acquisition unit 312 and the information transmission unit 314 are realized when the arithmetic unit 308 (processor) of the mobile terminal device 300 executes a program stored in the memory unit 310 of the mobile terminal device 300. For example, the information acquisition unit 312 and the information transmission unit 314 can be realized when the mobile terminal device 300, such as a smartphone, executes a predetermined application software. At least a part of the information acquisition unit 312 and the information transmission unit 314 may be realized by an IC (as described above), such as an ASIC or FPGA, provided in the mobile terminal device 300.

[0054] The information acquisition unit 312 acquires usage information supplied wirelessly from the power supply support device 200. The usage information supplied from the power supply support device 200 may be acquired via the communication unit 302. As described above, at least a portion of the usage information may be supplied from the adapter 100 to the mobile terminal device 300 (communication unit 302).

[0055] The information transmission unit 314 transmits (supplies) user information and usage information acquired by the information acquisition unit 312 to the server device 400. User information is identification information that indicates the user USR who possesses the mobile terminal device 300. User information is stored in advance, for example, by the storage unit 310 of the mobile terminal device 300. The information transmission unit 314 associates the user information and usage information and transmits them to the server device 400. Communication between the mobile terminal device 300 and the server device 400 can be performed via the network NW by the communication unit 302 described above.

[0056] The information transmission unit 314 may further transmit location information indicating the location of the mobile terminal device 300 (user USR) to the server device 400. The location information is acquired, for example, by a GNSS (Global Navigation Satellite System) sensor (not shown) that may be provided in the mobile terminal device 300.

[0057] Figure 5 is a block diagram of the server device 400 according to the first embodiment.

[0058] The server device 400 is a computer capable of communicating with the mobile terminal device 300. As shown in Figure 5, the server device 400 comprises a communication unit 402, an arithmetic unit 404, and a storage unit 406.

[0059] The communication unit 402 includes a communication module (not shown). The communication unit 402 communicates with the mobile terminal device 300 (communication unit 302) via the network NW.

[0060] The arithmetic unit 404 includes a processing circuit (not shown). This processing circuit includes, for example, one or more processors such as a CPU or GPU. This processing circuit may also include IC circuits such as an ASIC or FPGA.

[0061] The storage unit 406 includes one or more memory locations. These one or more memory locations include non-volatile memory such as ROM and flash memory. The storage unit 406 (one or more memory locations) may also include volatile memory such as RAM.

[0062] The arithmetic unit 404 includes an information acquisition unit 408, a usage mode determination unit 410, a power consumption determination unit 412, a power supply time determination unit 414, and a payment processing unit 416. The information acquisition unit 408, the usage mode determination unit 410, the power consumption determination unit 412, the power supply time determination unit 414, and the payment processing unit 416 are realized by the arithmetic unit 404 (processor) of the server device 400 executing a program stored in the storage unit 406 (memory) of the server device 400. At least a part of the information acquisition unit 408, the usage mode determination unit 410, the power consumption determination unit 412, the power supply time determination unit 414, and the payment processing unit 416 may be realized by an integrated circuit (as described above) such as an ASIC or FPGA provided in the server device 400.

[0063] The information acquisition unit 408 acquires user information and usage information transmitted from the mobile terminal device 300 (information transmission unit 314) via the communication unit 402.

[0064] The usage pattern determination unit 410 determines (identifies) the usage pattern of user USR based on user information and usage information. For example, the usage pattern determination unit 410 determines whether user USR, indicated by user information, and owner, indicated by usage information (owner information), are the same person. If user USR and owner are not the same person, the usage pattern determination unit 410 determines that user USR is using a power outlet 18 managed by someone other than user USR (owner).

[0065] The usage pattern determination unit 410 may determine, based on the user information and location information described above, whether the location from which power is being supplied to the powered object 12 is a user facility. A user facility is a facility (location) equipped with a power source provided (managed) by the user USR. User facilities include, for example, the user USR's home. Even if the location from which power is being supplied to the powered object 12 is not a user facility, the usage pattern determination unit 410 may determine that the user USR is using a power outlet 18 managed by someone other than the user USR (the owner). In that case, the relationship between the user USR and the user facility of the user USR is stored in advance by the storage unit 406.

[0066] The power quantity determination unit 412 determines (specifies) the amount of power supplied based on the usage information (power supply information). As described above, the amount of power supplied is the amount of power supplied to the power supply target object 12 via the connecting cable 24.

[0067] The power supply time determination unit 414 determines (specifies) the power supply time based on the usage information (power supply amount information). The power supply time is the time required by the user USR to supply power to the powered object 12. As described above, the power supply amount information indicates the amount of power supplied. The amount of power supplied is the product of the power of the power outlet 18 (output per unit time) and the power supply time. The power of the power outlet 18 can be stored in advance by the storage unit 406. Therefore, the power supply time determination unit 414 can determine the power supply time based on the information indicating the power of the power outlet 18 and the information indicating the amount of power supplied.

[0068] The power supply time may be measured using a timer or the like provided in the adapter 100, the power supply support device 200, or the mobile terminal device 300. In that case, information indicating the power supply time can be acquired by the information acquisition unit 408.

[0069] The payment processing unit 416 executes payment processing based on the determination result from the usage pattern determination unit 410, the determination result from the power consumption determination unit 412, and the determination result from the power supply time determination unit 414. The payment processing is the process of paying consideration to the owner of the power outlet 18 or the user USR who used the power outlet 18. More specifically regarding the payment processing, the payment processing unit 416 may execute the following processes (1) to (3).

[0070] (1) The payment processing unit 416 executes a process to pay the user USR a fee based on the power supply time. This fee is compensation for the time the user USR is tied up in supplying power to the rented power supply object 12. This fee may include money. The source of funds to pay this fee to the user USR is, for example, billed to the rental company that rented the power supply object 12 to the user USR. By executing this process by the payment processing unit 416, the user USR can supply power to the power supply object 12 without worrying about the rental fee being high relative to the actual usage time of the rented item. In other words, the payment processing unit 416 can encourage the user USR to use the power outlet 18. Information indicating the rental fee (rules related to rental) can be stored in advance by the storage unit 406.

[0071] (2) If a user USR uses a power outlet 18 that is managed by someone other than the user USR (the owner), the payment processing unit 416 executes a process to pay the owner who provides the power outlet 18 a fee corresponding to the amount of electricity supplied. The source of funds to pay this fee to the owner is, for example, billed to the user USR who used the power outlet 18. By executing this process, the payment processing unit 416 may encourage the owner to provide the power outlet 18 to the user USR.

[0072] (3) When a user USR uses a power source (power outlet 18) managed by the user USR, the payment processing unit 416 executes a process to pay the user USR a fee corresponding to the amount of electricity supplied. This fee may include money to reimburse the user USR for the electricity charges incurred by supplying power to the rented power supply object 12. The source of funds to pay this fee to the user USR is, for example, billed to the rental company that rented the power supply object 12 to the user USR. By executing this process by the payment processing unit 416, the user USR can supply power to the rented item without worrying about the electricity charges incurred by doing so. In other words, by executing this process, the payment processing unit 416 can encourage the user USR to use the power source (user facility) managed by the user USR.

[0073] Figure 6 is a flowchart showing the power supply method according to the first embodiment.

[0074] The power supply system 10 (computer system) described above can execute the power supply method shown in Figure 6. As shown in Figure 6, the power supply method includes a connection determination step S1, an authentication information acquisition step S2, an authentication step S3, a power supply control step S4, a usage information acquisition step S5, an information acquisition step S6, a usage pattern determination step S7, a power consumption determination step S8, a power supply time determination step S9, and a payment processing step S10. The power supply control step S4 includes a power supply restriction maintenance step S41 and a power supply restriction release step S42. As mentioned above, the power supply control unit 112 of the adapter 100 restricts power supply via the adapter 100 in its initial state.

[0075] In connection determination step S1, the connection determination unit 208 of the power supply support device 200 determines whether the power supply target object 12 and the adapter 100 are connected by the connection cable 24. If the connection determination unit 208 determines that the power supply target object 12 and the adapter 100 are not connected by the connection cable 24, the connection determination step S1 is executed again.

[0076] If the connection determination unit 208 determines that the power supply target object 12 and the adapter 100 are connected by the connection cable 24, the authentication information acquisition step S2 is started. In the authentication information acquisition step S2, the authentication information supply unit 210 of the power supply support device 200 supplies authentication information to the adapter 100 via the connection cable 24. As a result, the authentication information acquisition unit 108 of the adapter 100 acquires the authentication information.

[0077] Next, the process moves to authentication step S3, where the authentication unit 110 of the adapter 100 performs authentication based on the authentication information.

[0078] If authentication is not successful, the process proceeds to the power supply restriction maintenance step S41 of the power supply control step S4, and the power supply control unit 112 of the adapter 100 maintains the power supply restriction described above. If the power supply restriction maintenance step S41 is executed, the power supply method shown in Figure 6 is terminated.

[0079] If authentication is successful, the process proceeds to the power supply restriction release step S42 of the power supply control step S4, where the power supply control unit 112 of the adapter 100 releases (relaxes) the aforementioned power supply restriction. This allows power to be supplied to the powered object 12 via the adapter 100.

[0080] If the power supply restriction release step S42 is executed, the process proceeds to the usage information acquisition step S5, in which the usage information acquisition unit 212 of the power supply support device 200 acquires usage information. The usage information acquired by the usage information acquisition unit 212 is supplied from the power supply support device 200 to the mobile terminal device 300 via wireless communication.

[0081] Next, the process moves to information acquisition step S6, where the mobile terminal device 300 supplies the usage information acquired from the power supply support device 200, along with user information, to the server device 400. The mobile terminal device 300 supplies the usage information and user information to the server device 400 via the network NW. As a result, the information acquisition unit 408 of the server device 400 acquires the usage information and user information. The network NW may include the internet.

[0082] Next, the process moves to the usage pattern determination step S7, where the usage pattern determination unit 410 of the server device 400 determines (identifies) the usage pattern by user USR based on user information and usage information.

[0083] The usage pattern determination step S7 is performed after the information acquisition step S6 described above, and before the payment processing step S10 described later. The usage pattern determination step S7 may also be performed after the power consumption determination step S8 or the power supply time determination step S9 described later.

[0084] Next, the process moves to the power consumption determination step S8, where the power consumption determination unit 412 of the server device 400 determines (specifies) the amount of power supplied based on the usage information (power supply information). Furthermore, the process moves to the power supply time determination step S9, where the power supply time determination unit 414 of the server device 400 determines (specifies) the power supply time based on the specified amount of power supplied.

[0085] As described above, the power supply time may be measured by a timer, and information indicating the power supply time measured by the timer may be supplied to the server device 400 along with the usage information. In that case, the power consumption determination step S8 and the power supply time determination step S9 can be performed in any order.

[0086] Next, the process moves to payment processing step S10, where the payment processing unit 416 of the server device 400 performs payment processing based on the results of the usage pattern determination step S7, the power consumption determination step S8, and the power supply time determination step S9. The payment processing unit 416 may perform the processes (1) to (3) described above with respect to payment processing.

[0087] Thus, the power supply method shown in Figure 6 is completed. When the power supply control step S4 is executed, the power supply control unit 112 can determine whether the termination conditions described above have been met. If the power supply control unit 112 determines that the termination conditions have been met, it returns to the initial state described above. That is, if the power supply control unit 112 determines that the termination conditions have been met, it resumes the power supply restriction described above.

[0088] According to the power supply system 10 and power supply method described above, the owner of the power outlet 18 connects the adapter 100 to the power outlet 18. This allows the owner to easily provide power supply equipment to the user USR. Moreover, according to the power supply system 10 and power supply method described above, the owner can receive compensation when their power outlet 18 is used by the user USR.

[0089] Furthermore, according to the power supply system 10 and power supply method described above, the user USR connects the object to be powered 12 and the adapter 100 with a connecting cable 24. This allows the user USR to easily supply power to the object to be powered 12 without having to remove the battery 20. Moreover, according to the power supply system 10 and power supply method described above, the user USR can receive compensation based on the power supply time or the amount of power supplied, depending on the usage.

[0090] Furthermore, if authentication by a legitimate user USR is not successful, the adapter 100 restricts the supply of power to the powered object 12. This prevents unauthorized users from using the power outlet 18.

[0091] (Second embodiment) In the second embodiment, explanations that overlap with those of the first embodiment will be omitted as appropriate. Furthermore, in the figures used in the second embodiment, components identical to those described in the first embodiment will be denoted by the same reference numerals.

[0092] Figure 7 is a schematic diagram of the power supply system 10 (power supply system 10A) according to the second embodiment.

[0093] The power supply system 10A comprises an adapter 100 (adapter 100A), a power supply support device 200 (power supply support device 200A), a mobile terminal device 300 (mobile terminal device 300A, terminal device 14), and a server device 400. In this embodiment, the mobile terminal device 300A, rather than the power supply support device 200A, functions as the terminal device 14, which is an authentication device that supplies authentication information to the adapter 100A. In other words, in this embodiment, the mobile terminal device 300A is equipped with the terminal device 14. In this respect, the power supply system 10A according to this embodiment differs from the power supply system 10 according to the first embodiment (Figures 1 to 6) at least.

[0094] Figure 8 is a block diagram of adapter 100A according to the second embodiment.

[0095] As shown in Figure 8, the adapter 100A comprises a communication unit 114, a first connection unit 102, a second connection unit 104, and a control unit 106.

[0096] The communication unit 114 includes a communication module (not shown). This communication module allows the communication unit 114 to communicate wirelessly with the mobile terminal device 300A (communication unit 302). Wireless communication includes, for example, short-range wireless communication such as Bluetooth®.

[0097] Similar to the first embodiment, the control unit 106 includes an authentication information acquisition unit 108, an authentication unit 110, and a power supply control unit 112 (see also Figure 2). In this embodiment, the authentication information acquisition unit 108 acquires authentication information supplied from the mobile terminal device 300A via the communication unit 114.

[0098] Figure 9 is a block diagram of the power supply support device 200A according to the second embodiment.

[0099] As shown in Figure 9, the power supply support device 200A comprises a connector 202, a communication unit 204, and a control unit 206 (control unit 206A). The control unit 206A comprises a usage information acquisition unit 212 and a usage information supply unit 214.

[0100] The usage information acquired by the control unit 206A (power supply support device 200A) includes, but is not limited to, owner information and power supply amount information. For example, the communication unit 114 of the adapter 100 may supply owner information to the communication unit 302 of the mobile terminal device 300. In that case, the control unit 206A (power supply support device 200A) does not need to acquire the owner information.

[0101] Figure 10 is a block diagram of a mobile terminal device 300A according to the second embodiment.

[0102] As shown in Figure 10, the mobile terminal device 300A comprises a communication unit 302, a display unit 304, an operation unit 306, a calculation unit 308, and a storage unit 310. The calculation unit 308 comprises an authentication information supply unit 316, an information acquisition unit 312, and an information transmission unit 314.

[0103] The authentication information supply unit 316 supplies authentication information to the adapter 100 via the communication unit 302. As a result, the mobile terminal device 300A functions as the terminal device 14 described above. The authentication information supplied to the adapter 100A by the authentication information supply unit 316 can be stored in advance, for example, in the storage unit 310 of the mobile terminal device 300A.

[0104] The authentication information supply unit 316 supplies authentication information to the adapter 100 based on instructions from the user USR, for example, via the operation unit 306, but is not limited to this. For example, the mobile terminal device 300A (communication unit 302) may automatically attempt wireless communication with the adapter 100A periodically or continuously. In this case, the user USR can position the adapter 100 within the wireless communication range of the mobile terminal device 300A by approaching the adapter 100A to a certain extent while holding the mobile terminal device 300A. This allows wireless communication between the mobile terminal device 300A and the adapter 100A to be started automatically. The mobile terminal device 300A (for example, the authentication information supply unit 316) may also perform processing to notify the user USR that wireless communication with the adapter 100A has been successful. This allows the mobile terminal device 300A to prompt the user USR to perform an operation to supply authentication information to the adapter 100. The process for notifying the user USR that wireless communication has been successful may include, but is not limited to, displaying a message on the display unit 304 of the mobile terminal device 300A.

[0105] The information acquisition unit 312 can acquire usage information (owner information, power supply amount information) in the same manner as in the first embodiment. As described above, owner information may be supplied from the adapter 100A to the mobile terminal device 300A via wireless communication. In that case, the information acquisition unit 312 can acquire the owner information supplied from the adapter 100A via wireless communication.

[0106] The explanation of the information transmission unit 314 is omitted as it overlaps with that of the first embodiment.

[0107] The server device 400, like the first embodiment, includes a communication unit 402, a calculation unit 404, and a storage unit 406. The calculation unit 404 includes an information acquisition unit 408, a usage mode determination unit 410, a power consumption determination unit 412, a power supply time determination unit 414, and a payment processing unit 416 (see also Figure 5). The server device 400 can communicate with the mobile terminal device 300A (terminal device 14) via the communication unit 402. A more detailed description of the server device 400 is omitted as it would overlap with the first embodiment.

[0108] Figure 11 is a flowchart of the power supply method according to the second embodiment.

[0109] The power supply system 10A (computer system) described above can implement the power supply method shown in Figure 11. The power supply method shown in Figure 11 differs from the power supply method according to the first embodiment (Figure 6) in that it does not include the connection determination step S1. The authentication information acquisition step S2 shown in Figure 11 is started, for example, when a user USR gives an instruction to the mobile terminal device 300A via the operation unit 306. In the authentication information acquisition step S2, the authentication information supply unit 316 of the mobile terminal device 300A supplies authentication information to the adapter 100A via wireless communication. The explanation of each step (S3 to S10) from the authentication step S3 onward shown in Figure 11 is omitted because it overlaps with the first embodiment.

[0110] According to this embodiment, similar to the first embodiment, the owner of the power outlet 18 can easily provide power supply equipment to the user USR by connecting the adapter 100A to the power outlet 18. Moreover, the owner can receive compensation when the owner's power outlet 18 is used by the user USR.

[0111] Furthermore, according to this embodiment, the user USR connects the power supply target object 12 and the adapter 100A with a connecting cable 24 and supplies authentication information to the adapter 100A using a portable terminal device 300A. This allows the user USR to easily supply power to the power supply target object 12 without having to remove the battery 20. Moreover, the user USR can receive compensation based on the power supply time or the amount of power supplied, depending on the usage.

[0112] Furthermore, if authentication by a legitimate user USR is not successful, the adapter 100A restricts the supply of power to the powered object 12. This prevents unauthorized users from using the power outlet 18.

[0113] As described above, according to this embodiment, authentication information is supplied from the mobile terminal device 300A to the adapter 100A via wireless communication. Owner information can also be supplied from the adapter 100A to the mobile terminal device 300A via wireless communication. In this case, the connection cable 24 according to this embodiment only needs to function as at least a power supply cable among the power supply cable and the communication cable.

[0114] Each of the above embodiments may be modified as follows. In the following modifications, explanations that overlap with those of the embodiments will be omitted as appropriate. Also, in the figures used in the following modifications, components identical to those described in each embodiment will be denoted by the same reference numerals.

[0115] (Variation 1) When a user USR uses a power supply (charging equipment) provided by that user USR, authentication based on authentication information (see each embodiment above) is not required. In other words, when a user USR uses a power supply managed by that user USR, the adapter 100 may be omitted.

[0116] In that case, the usage pattern determination unit 410 of the server device 400 can determine whether or not power is being supplied at the user's facility based on user information and location information supplied from the mobile terminal device 300.

[0117] Furthermore, if the adapter 100 is omitted, the usage information acquisition unit 212 of the power supply support device 200 does not need to acquire owner information. In this case, the usage information acquisition unit 212 may acquire only power supply amount information as usage information, for example. The power supply amount information (usage information) acquired by the usage information acquisition unit 212 is transmitted to the server device 400 via the mobile terminal device 300. This allows the power supply amount determination unit 412 of the server device 400 to determine (specify) the amount of power supplied. Also, the power supply time determination unit 414 of the server device 400 can determine (specify) the power supply time. Furthermore, the payment processing unit 416 of the server device 400 may appropriately execute payment processing based on the determination result by the power supply amount determination unit 412 and the determination result by the power supply time determination unit 414 (see also the embodiments described above).

[0118] (Modification 2) Figure 12 is a block diagram of the mobile terminal device 300 (mobile terminal device 300B) according to Modification 2. Figure 13 is a block diagram of the server device 400 (server device 400B) according to Modification 2.

[0119] In relation to the second embodiment, the mobile terminal device 300B (terminal device 14) further comprises a request unit 318. The server device 400B further comprises a user authentication unit 418 and an authentication information issuing unit 420.

[0120] The request unit 318 requests the server device 400B to issue authentication information. The user authentication unit 418 of the server device 400B authenticates the user USR in response to the request from the request unit 318. If the authentication of the user USR by the user authentication unit 418 is successful, the authentication information issuing unit 420 issues authentication information to the mobile terminal device 300B via the network NW (see also Figure 7). As a result, the mobile terminal device 300B (terminal device 14) can supply the authentication information issued by the authentication information issuing unit 420 to the adapter 100.

[0121] The request unit 318 may request the server device 400B to issue authentication information in response to a predetermined operation (biometric authentication) performed by the user USR. For example, the mobile terminal device 300B may be equipped with an image sensor (camera). In this case, the request unit 318 may acquire imaging information showing the user USR's body (e.g., face) using the camera. The request unit 318 supplies the imaging information acquired by the camera to the server device 400B via the network NW. As a result, the user authentication unit 418 of the server device 400B can authenticate the user USR based on the imaging information. The user authentication unit 418 can authenticate the user USR by, for example, comparing the imaging information supplied from the request unit 318 with image information (such as a photograph of the user USR's face) that has been registered in advance regarding the user USR.

[0122] Furthermore, for example, the mobile terminal device 300B may be equipped with a sound sensor (microphone). In this case, the request unit 318 may acquire voice information using the microphone. The voice information may include, for example, information indicating the user USR's voiceprint (voiceprint information). The request unit 318 supplies the voice information acquired by the microphone to the server device 400B via the network NW. This allows the user authentication unit 418 of the server device 400B to authenticate the user USR based on the voice information. The user authentication unit 418 can authenticate the user USR by, for example, comparing the voice information supplied from the request unit 318 with voice information (such as voiceprint information for verification) that has been registered in advance regarding the user USR.

[0123] Furthermore, for example, the mobile terminal device 300B may be equipped with a fingerprint sensor. In this case, the request unit 318 may acquire fingerprint information indicating the user USR's fingerprint using the fingerprint sensor. The request unit 318 supplies the fingerprint information acquired by the fingerprint sensor to the server device 400B via the network NW. As a result, the user authentication unit 418 of the server device 400B can authenticate the user USR based on the fingerprint information. The user authentication unit 418 can authenticate the user USR, for example, by comparing the fingerprint information supplied from the request unit 318 with the user USR's fingerprint information that has been registered in advance.

[0124] According to this modified version, the authentication information supplied to the adapter 100 is issued by the server device 400B only if the server device 400B has successfully authenticated the user USR. This improves the reliability of the authentication information supplied to the adapter 100. Furthermore, according to this modified version, it is possible to deter anyone other than the user USR from impersonating the user USR and using the adapter 100.

[0125] (Variation 3) In relation to Modification 2, although not shown in the figures, the power supply support device 200 may be equipped with a request unit 318. That is, according to the first embodiment, the power supply support device 200 is equipped with a terminal device 14. In this case, the power supply support device 200 (terminal device 14) may be equipped with a request unit 318. In addition, the power supply support device 200 may be equipped with various sensors such as a camera, microphone, and fingerprint sensor as appropriate (see also Modification 2).

[0126] The request unit 318 in the power supply support device 200 transmits information (biometric information) indicating the user USR's fingerprint, voiceprint, etc., detected by various sensors, to the server device 400 via the mobile terminal device 300. This prompts the request unit 318 in the power supply support device 200 to request the issuance of authentication information. The user authentication unit 418 of the server device 400 authenticates the user USR based on the above-mentioned biometric information.

[0127] If authentication by the user authentication unit 418 is successful, the authentication information issuing unit 420 of the server device 400 issues authentication information to be supplied to the adapter 100. The authentication information issuing unit 420 supplies the authentication information to the power supply support device 200 via the mobile terminal device 300. When the authentication information is supplied to the adapter 100 by the power supply support device 200, authentication by the authentication unit 110 of the adapter 100 (see each embodiment) can be performed.

[0128] (Modification 4) The power supply support device 200 or the portable terminal device 300 may be equipped with an image sensor (camera). In that case, owner information may be acquired by the camera. The predetermined identifier includes, but is not limited to, a two-dimensional code. The predetermined identifier may be attached to, but is not limited to, the housing of the adapter 100. The predetermined identifier may be posted or displayed around the adapter 100.

[0129] The power supply support device 200 or the mobile terminal device 300 may be equipped with an NFC (Near Field Communication) reader. Owner information may also be stored on a recording medium readable by the NFC reader. In this case, the owner information stored on the recording medium may be retrieved by the NFC reader. Examples of recording media readable by the NFC reader include NFC tags and IC chips. Such recording media may be provided, for example, in the adapter 100.

[0130] (A combination of multiple variations) The various modifications described above may be combined as appropriate within the bounds of consistency. The various embodiments described above may be combined as appropriate within the bounds of consistency.

[0131] With regard to each of the embodiments described above, the following additional information is disclosed.

[0132] (Note 1) The power supply system (10) according to this disclosure comprises an adapter (100) that can be connected to a power outlet (18) and can supply power supplied from the power outlet to an object to be powered (12) via a connecting cable (24), and a terminal device (14) that can supply authentication information to the adapter, wherein the adapter comprises an authentication unit (110) that performs authentication based on the authentication information supplied from the terminal device, and a power supply control unit (112) that restricts the power supply to the object to be powered if authentication by the authentication unit is not successful, and allows the power supply to the object to be powered if authentication by the authentication unit is successful. This provides a better power supply system for both the owner who provides the power outlet and the user who uses the power outlet.

[0133] (Note 2) The power supply system described in Appendix 1 may also be a power supply system in which the terminal device is provided on the object to be powered, and when the object to be powered and the adapter are connected by the connection cable, the terminal device supplies the authentication information to the adapter via the connection cable. This allows the user to easily supply power to the object to be powered 12 without having to remove the battery.

[0134] (Note 3) The power supply system described in Appendix 1 may also be a power supply system in which the terminal device is provided on a portable terminal device (300) possessed by a user (USR) who uses the object to be powered, and the portable terminal device can supply the authentication information to the adapter via wireless communication.

[0135] (Note 4) The power supply system described in Appendix 1 may also be a power supply system comprising: an energy supply determination unit (412) that determines the amount of power supplied, which is the amount of power supplied from the power outlet to the object to be powered via the adapter; and a payment processing unit (416) that processes the payment of compensation to the owner who provides the power outlet, corresponding to the amount of power supplied determined by the energy supply determination unit. In this way, the owner can receive compensation when the owner's power outlet is used by users.

[0136] (Note 5) The power supply system described in Appendix 1 may also be a power supply system comprising: a power supply time determination unit (414) that determines the power supply time required to supply power to the power supply target object leased from the lending business operator to the user (USR); and a payment processing unit (416) that processes the payment of a fee to the user corresponding to the power supply time determined by the power supply time determination unit. This allows the payment processing unit to encourage the user to use the power outlet.

[0137] (Note 6) The power supply system described in Appendix 1 may also include: an energy quantity determination unit (412) that determines the amount of power supplied to the power supply target object when power is supplied to the power supply target object, which is the amount of power supplied to the power supply target object, from a power source provided by the user, when power is supplied to the power supply target object, which is the amount of power supplied to the power supply target object, and a payment processing unit (416) that performs processing to pay the user a fee corresponding to the amount of power supplied determined by the energy quantity determination unit. By performing this processing, the payment processing unit can encourage the user to use the power source (user facility) provided by the user.

[0138] (Note 7) The power supply system described in Appendix 1 may also include a server device (400) capable of communicating with the terminal device, wherein the terminal device includes a request unit (318) that requests the server device to issue the authentication information, and the terminal device supplies the authentication information issued by the server device to the adapter. This improves the reliability of the authentication information supplied to the adapter.

[0139] (Note 8) The power supply system described in Appendix 1 may also be a power supply system in which the object to be powered includes a mobile object.

[0140] (Note 9) The power supply system (10) relating to this disclosure includes a power supply determination unit (412) that determines the amount of power supplied to a power supply target object (12) leased from a lending business operator to a user (USR) when the user provides power to the power supply target object, and a payment processing unit (416) that processes the payment of a fee to the user corresponding to the amount of power supplied determined by the power supply determination unit. This allows the payment processing unit to encourage the user to use the power outlet.

[0141] (Note 10) The power supply method according to this disclosure includes an authentication step (S3) in which an adapter (100) that can be connected to a power outlet (18) and can supply power supplied from the power outlet to an object to be powered (12) via a connecting cable (24) performs authentication based on authentication information supplied from a terminal device (14), and a power supply control step (S4) in which, if authentication in the authentication step is not successful, the adapter restricts the power supply to the object to be powered, and if authentication in the authentication step is successful, the adapter allows the power supply to the object to be powered. This provides a better power supply system for both the owner who provides the power outlet and the user who uses the power outlet.
