Fig. 3 is a flowchart for explaining an operation example of charging system 200 and external system 300 according to embodiment 1.

[0029] In this embodiment, a charging reservation is scheduled in advance before step S101 in the sequence diagram of FIG. 2. The charging reservation is scheduled for one specific electric vehicle 500 (hereinafter referred to as the electric vehicle 500 RES ) is the charging reservation period T RES In this case, a specific charger 210 (hereinafter referred to as the charger 210 RES Before step S101 in the sequence diagram of FIG. 2 , the charging reservation is stored in the external system 300 and is in a state where it can be accessed by the first external device 310, the second external device 320, and the third external device 330.

[0030] Steps S101 to S107 will be described with reference to Fig. 2. Steps S108 to S111 will be described with reference to Fig. 2 and Fig. 3. Note that Fig. 2 illustrates the case where "NO" is determined in step S108.

[0031] In step S101, the first external device 310 transmits the identifier pair PAIR to the communicator 221 via the network 400. 13 By the transmission in step S101, the controller 223 transmits the identifier pair PAIR via the communicator 221. 13 Receive.

[0032] Identifier pair PAIR 13 is a pair of a first identifier and a third identifier. The first identifier is a RES The third identifier is an identifier for identifying the charger 210 to be used in the charging schedule. RES The third identifier is associated with the first identifier.

[0033] In this embodiment, the first identifier is the electric vehicle 500 RES The first identifier is also associated with the date and time information of the scheduled charging period T. That is, the date and time information of the scheduled charging period can be referenced by the first identifier. RES More specifically, the scheduled charging date and time information includes information indicating the scheduled charging period T RES The information includes the start and end times of the

[0034] Next, in step S102, the controller 223 generates the identifier pair PAIR 13 are stored in the correspondence table of the storage unit 222. Specifically, the identifier pair PAIR 13 are stored in a correspondence table in a state where they are associated with each other.

[0035] In step S103, the electric vehicle 500 is connected to the charger 210. Hereinafter, the charger 210 connected to the electric vehicle 500 in step S103 is referred to as the charger 210. CON It is sometimes referred to as.

[0036] By connecting in step S103, the charger 210 CON detects a change in the connection state. Here, the change in the connection state is detected by the charger 210 CON When the electric vehicle 500 is not connected to the charger 210 CON This is a change to a state in which the electric vehicle 500 is connected to the power source.

[0037] Next, in step S104, the charger 210 CON transmits the connection status change notification and the second identifier to the communicator 221 via the control device 230.

[0038] Next, in step S105 , the controller 223 causes the communicator 221 to transmit a connection status change notification and the second identifier to the second external device 320 via the network 400 .

[0039] In steps S104 and S105, the connection state change notification and the second identifier are transmitted to the charger 210. CON The connection status change notification is transmitted from the charger 210 to the second external device 320 via the control device 230, the charging control device 220, and the network 400. The connection status change notification includes information indicating that a connection status change has occurred and information indicating the time when the connection status change has occurred. CON is the identifier for

[0040] Next, in step S106, in response to receiving the connection state change notification and the second identifier, the second external device 320 transmits the identifier pair PAIR to the communicator 221 via the network 400.12 Send the identifier pair PAIR 12 is a pair of a first identifier and a second identifier. By the transmission in step S106, the controller 223 transmits the identifier pair PAIR via the communicator 221. 12 Receive.

[0041] In step S106 according to a non-limiting specific operation example, the second external device 320 recognizes the time when the connection state change occurred based on the connection state change notification received in step S105. In this specific operation example, the second external device 320 recognizes the time when the connection state change occurred based on the time when the connection state change occurred. RES Charging reservation period T RES The second external device 320 determines that the first identifier corresponds to the start time of the scheduled charging. The second external device 320 then accesses the first identifier associated with the date and time information of the scheduled charging. The second external device 320 then transmits the first identifier together with the second identifier to the communicator 221 via the network 400.

[0042] Next, in step S107, the controller 223 determines the identifier pair PAIR 12 are stored in the correspondence table of the storage unit 222. Specifically, the identifier pair PAIR 12 are stored in a correspondence table in a state where they are associated with each other.

[0043] Next, in step S108, the controller 223 compares the second identifier with the third identifier. As shown in Fig. 3, if it is determined in step S108 that the second identifier and the third identifier match, the process proceeds to step S109. On the other hand, if it is determined that the second identifier and the third identifier do not match, the process proceeds to step S110.

[0044] Specifically, in step S108, the controller 223 searches the storage unit 222 for a pair including the first identifier. 12 and the identifier pair PAIR 13 The controller 223 determines whether the identifier pair PAIR 12 and the second identifier in the identifier pair PAIR 13The controller 223 then extracts a third identifier from the first identifier and determines whether the extracted second identifier and third identifier match. In this way, in step S108, the controller 223 uses the first identifier as a search index and determines whether the second identifier and third identifier extracted through the search match.

[0045] In step S108, if the second identifier and the third identifier match, the charger 210 CON and charger 210 RES and the electric vehicle 500 RES On the other hand, in step S108, if the second identifier and the third identifier do not match, it means that the charger 210 CON and charger 210 RES Unlike the electric vehicle 500 RES This means that the reserved charger 210 is connected to a different charger 210. CON and charger 210 RES This shows a different situation.

[0046] In this embodiment, in step S109 as well as step S110, the controller 223 controls the charger 210 CON As a result, the charger 210 CON Electric vehicle 500 RES A current flows through the electric vehicle 500 RES Specifically, the controller 223 controls the charger 210 via the control device 230. CON Charging control is performed.

[0047] After step S110, in step S111, the controller 223 causes the communicator 221 to transmit an error response to the third external device 330 via the network 400. In the first embodiment, the error response includes information indicating an abnormality. The transmission in step S111 enables the third external device 330 to deal with the abnormality. In this embodiment, the display 335 of the third external device 330 displays the information indicating the abnormality.

[0048] In this embodiment, the external system 300 is a vehicle dispatch system. The transmission in step S111 enables the third external device 330 to deal with the abnormality and optimize vehicle dispatch. The optimization is, for example, a change in the dispatch plan for the multiple electric vehicles 500.

[0049] As can be understood from the above description, in this embodiment, the electric vehicle 500 can be charged by the charger 210 connected to it, regardless of whether the electric vehicle 500 is connected to the reserved charger 210 or a charger 210 different from the reserved charger 210. This can improve convenience for the user of the electric vehicle 500.

[0050] Several other embodiments will be described below. In the following, elements common to the embodiments already described and the embodiments to be described thereafter will be given the same reference numerals, and their description may be omitted. The descriptions of the respective embodiments may be mutually applicable unless technically inconsistent. The respective embodiments may be combined with each other unless technically inconsistent.

[0051] Second Embodiment In a second embodiment, the error response in step S111 is RES and charger 210 CON The display 335 of the third external device 330 includes information indicating that the charger 210 is different from the charger 210. RES and charger 210 CON Displays information indicating that the

[0052] Third Embodiment In a third embodiment, the error response in step S111 includes information indicating that the charging schedule needs to be modified. The display 335 of the third external device 330 displays the information indicating that the charging schedule needs to be modified.

[0053] (Comparison of Embodiments 1, 2, and 3) The error response in step S111 in embodiment 2 can provide the third external device 330 with more detailed abnormality information regarding the connection between the electric vehicle 500 and the charger 210 than the error response in step S111 in embodiment 1. The error response in step S111 in embodiment 3 can provide the third external device 330 with more detailed abnormality information regarding the connection between the electric vehicle 500 and the charger 210 than the error response in step S111 in embodiment 2.

[0054] Consider the demarcation point of responsibilities between the operator of the charging system 200 and the operator of the external system 300. For example, the second embodiment can be adopted when the operator of the charging system 200 has a wider range of responsibilities than the first embodiment. The third embodiment can be adopted when the operator of the charging system 200 has a wider range of responsibilities than the second embodiment.

[0055] Step S111 can be implemented based on the Hypertext Transfer Protocol (HTTP). In one example, the information indicating an abnormality in step S111 of the first embodiment corresponds to an HTTP error, specifically, an HTTP error in the 400s or 500s. RES and charger 210 CON The information indicating that the charging schedule needs to be corrected in step S111 of the third embodiment is a message included in the HTTP body portion.

[0056] In addition, in the second and third embodiments, since charging control is performed by utilizing the technology disclosed herein, a response is made with an HTTP normal response number such as 200, and an error code (second embodiment) or a body message (third embodiment) indicating that the system is not operating in an accurate correspondence relationship can be sent. RESThis allows for more accurate communication of operational status, such as that service provision to the system is running normally, but that there is a problem with the consistency of the states between the systems.

[0057] (Technology Applicable to the First to Third Embodiments) Hereinafter, a description will be given of technology applicable to the first to third embodiments described above.

[0058] In the above-described first to third embodiments, the external system 300 is a vehicle dispatch system. The external system 300 may be another system such as a vehicle operation system, a system for social infrastructure, or an inter-business collaboration platform.

[0059] In the first to third embodiments described above, the number of electric vehicles 500 compatible with the charging system 200 is plural. However, the number of electric vehicles 500 compatible with the charging system 200 may be one.

[0060] In the first to third embodiments described above, the charging system 200 includes a plurality of chargers 210. However, the charging system 200 may include only one charger 210.

[0061] The concept of a charger encompasses a charger / discharger. When the charger 210 is a charger / discharger, it is connected to the electric vehicle 500 and can receive power from the electric vehicle 500. This allows power to be discharged from the electric vehicle 500. The charger 210 may or may not be a charger / discharger.

[0062] The charger 210 may include a display. For example, the error response in step S111 is transmitted to the charger 210 via the control device 230. In the first embodiment, information indicating the abnormality is displayed on the display of the charger 210. In the second embodiment, RES and charger 210 CON and the charging schedule are different is displayed on the display of the charger 210. In the third embodiment, information indicating that the charging schedule needs to be corrected is displayed on the display of the charger 210.

[0063] In the first to third embodiments described above, the first external device 310 may be, for example, a server of the external system 300 or an information terminal of a user of the electric vehicle 500. The second external device 320 may be a server of the external system 300 or an information terminal of a user of the electric vehicle 500. The third external device 330 may be an information terminal having a display 335 in the external system 300 or an information terminal of a user of the electric vehicle 500. The example shown in FIG. 1 corresponds to a case where the first external device 310 is a server of the external system 300, the second external device 320 is another server of the external system 300, and the third external device 330 is an information terminal having a display 335 in the external system 300.

[0064] The external system 300 is a vehicle dispatch system or a vehicle operation system. When the third external device 330 is an information terminal having a display 335 in the external system 300, this information terminal receives the operation error response. The information terminal is a device or subsystem having a UI (User Interface) for monitoring operation, controlling operation, notifying a system administrator, or notifying a user.

[0065] When at least two of the first external device 310, the second external device 320, and the third external device 330 are the same type of device, the same device may serve as both the first external device 310 and the second external device 320. For example, when the first external device 310 and the second external device 320 are servers of the external system 300, the same server may serve as both the first external device 310 and the second external device 320. Furthermore, when the first external device 310, the second external device 320, and the third external device 330 are information terminals of users of the electric vehicle 500, the same information terminal may serve as both the first external device 310, the second external device 320, and the third external device 330.

[0066] The electric vehicle 500 may be a four-wheeled vehicle or a two-wheeled vehicle. The electric vehicle may be a private vehicle or a commercial vehicle. The electric vehicle 500 may also be an AGV (Automatic Guided Vehicle).

[0067] In the above-described first to third embodiments, the electric vehicle (electric moving body) is the electric vehicle 500. However, the electric moving body is not limited to the electric vehicle 500. Other examples of the electric moving body include drones, electric ships, electric aircraft (commonly known as "flying cars"), fixed-wing aircraft, rotary-wing aircraft, etc. In the above-described first to third embodiments, the term "electric vehicle 500" may be replaced with "electric moving body."

[0068] One device may serve as two of the first external device 310, the second external device 320, and the third external device 330, and another device may constitute the remaining device.

[0069] The power storage device included in the electric vehicle 500 is not particularly limited. The power storage device may include a storage battery or a capacitor. The storage battery is, for example, a lithium-ion secondary battery. The power storage device may include only one of a storage battery and a capacitor, or may include both.

[0070] The order and content of the steps in the above-described flowcharts and sequence diagrams can be changed as appropriate. Furthermore, the above-described control does not necessarily have to be performed according to the flowcharts and sequence diagrams. The above-described control may be implemented, for example, by a state transition machine.

[0071] In step S101 in the first to third embodiments described above, the first external device 310 transmits the first identifier and the third identifier to the communicator 221 via the network 400 .

[0072] In step S101 according to the modifications of the first to third embodiments, the first external device 310 transmits the first identifier to the communication unit 221 via the network 400. The controller 223 of the charge control device 220 appropriately sets the charge reservation period T RESThe controller 223 acquires a third identifier by selecting a charger 210 that can be reserved for the first external device 310. The controller 223 may also transmit the identifier (third identifier) ​​of the charger 210 selected to the external system 300. The third identifier acquired in this manner is used as the third identifier in step S102 and thereafter, instead of the third identifier transmitted from the first external device 310.

[0073] In step S106 in the first to third embodiments described above, the second external device 320 transmits the first identifier and the second identifier to the communicator 221 via the network 400.

[0074] In step S106 according to the modifications of the first to third embodiments, the second external device 320 transmits the second identifier to the communication unit 221 via the network 400. The controller 223 of the charge control device 220 determines whether or not the second external device 320 is to be charged during the time period (the charging reservation period T RES ) is approved to connect the electric vehicle 500 to the charger 210 indicated by the second identifier in the charging reservation period T RES The first identifier thus acquired is used as the first identifier in step S107 and thereafter, in place of the first identifier transmitted from the second external device 320.

[0075] In the above-described first to third embodiments, steps S101 to S102 may be performed first, and then steps S103 to S107. Alternatively, steps S103 to S107 may be performed first, and then steps S101 to S102.

[0076] (Method and System Understood from the Above Description) As can be understood from the above description, the present disclosure discloses a charging control method. Specifically, the charging control method is performed by the charging control device 220.

[0077] In one example, the charging control method includes a first step, a second step, and a third step. In the first step, when electric vehicle 500 is connected to charger 210, a first identifier is received from first external device 310. The first identifier is an identifier that identifies a pre-planned charging schedule for electric vehicle 500. In the second step, a second identifier is received from second external device 320. The second identifier is an identifier of charger 210 to which electric vehicle 500 is connected. In the third step, it is determined whether the second identifier and a third identifier are the same. The third identifier is an identifier of charger 210 to be used in the charging schedule. The third identifier is associated with the first identifier. In the charging control method, even if the second identifier and the third identifier are different, charging control of electric vehicle 500 is performed by charger 210 to which electric vehicle 500 is connected. This configuration is suitable for improving convenience for the user of electric vehicle 500.

[0078] In the above configuration, the “charging control of the electric vehicle 500 ” specifically involves charging the electric vehicle 500 by supplying a current to the electric vehicle 500 .

[0079] The expression "receiving the first identifier from the first external device 310 when the electric vehicle 500 is connected to the charger 210" in the above configuration will be described below. This expression encompasses a form in which the timing at which the first identifier is received from the first external device 310 is earlier than the timing at which the electric vehicle 500 is connected to the charger 210, a form in which the timing at which the first identifier is received from the first external device 310 is simultaneous with the timing at which the electric vehicle 500 is connected to the charger 210, and a form in which the timing at which the electric vehicle 500 is later than the timing at which the electric vehicle 500 is connected to the charger 210. Typically, the timing at which the first identifier is received from the first external device 310 is earlier than the timing at which the electric vehicle 500 is connected to the charger 210, such as the timing at which a charging reservation is made.

[0080] In the above configuration, the "electric vehicle 500" in the "pre-planned charging schedule for the electric vehicle 500" is the electric vehicle 500 according to the first to third embodiments. RES The "charger 210 to which the electric vehicle 500 is connected" may be the charger 210 of the first to third embodiments.CON The "charger 210 to be used in the charging schedule" may be the charger 210 of the first to third embodiments. RES It is possible.

[0081] In one example, the charge control method includes a fourth step. In the fourth step, if the second identifier and the third identifier are different, information indicating an abnormality is transmitted to the third external device 330. This configuration enables the third external device 330 to deal with the abnormality.

[0082] In one example, the charging control method includes a fifth step. In the fifth step, if the second identifier and the third identifier are different, information indicating that the charger 210 to be used in the charging schedule is different from the charger 210 to which the electric vehicle 500 is actually connected is transmitted to the third external device 330. This configuration enables the third external device 330 to deal with the abnormality.

[0083] In one example, the charging control method includes a sixth step. In the sixth step, if the second identifier and the third identifier are different, information indicating that the charging schedule needs to be modified is transmitted to the third external device 330. This configuration enables the third external device 330 to deal with the abnormality.

[0084] In one example, the first identifier is also associated with scheduled charging date and time information. That is, the scheduled charging date and time information can be referenced using the first identifier. Specifically, the scheduled charging date and time information indicates a period during which charging is scheduled. More specifically, the scheduled charging date and time information includes scheduled charging date and time information. Specifically, the scheduled charging date and time information includes information indicating the start time and end time of the period during which charging is scheduled.

[0085] As can be understood from the above description, the present disclosure discloses a charging control device 220 .

[0086] The charging control device 220 includes a communication unit 221, a storage unit 222, and a controller 223. The communication unit 221 communicates with the first external device 310 or the second external device 320.

[0087] In one example, the memory 222 stores a first identifier and a third identifier in association with each other. The first identifier is an identifier that identifies a pre-planned charging schedule for the electric vehicle 500. The third identifier is an identifier of the charger 210 that is to be used in the charging schedule. When the electric vehicle 500 is connected to the charger 210, the controller 223 receives the first identifier from the first external device 310 via the communicator 221, and receives the second identifier from the second external device 320 via the communicator 221. The second identifier is the identifier of the charger 210 to which the electric vehicle 500 is connected. Upon receiving the first identifier, the controller 223 determines whether the second identifier and the third identifier are the same. The third identifier is associated with the first identifier. Even if the second identifier and the third identifier are different, the controller 223 executes charging control of the electric vehicle 500 by the charger 210 to which the electric vehicle 500 is connected.
