Summary of the Invention

Problems to be Solved by the Invention

[0004] The present inventors have investigated a management system for providing total charger information to charger users, based on Japanese Patent Publication No. 2023-105425. Total charger information refers to centralized information (including information such as electricity unit price and business hours) from multiple chargers. Total charger information is composed of charger-compatible information corresponding to the charger information held by each of the multiple chargers. Users of electric vehicles view the total charger information displayed on their mobile devices via an app and decide which charger to use to charge their electric vehicle. Subsequently, the user charges their electric vehicle at the selected charger based on the electricity unit price and other information requested by the charger.

[0005] In this process, the charger administrator in the management system enters the change information into an information input terminal when changing charger information. The change information is then sent from the information input terminal to the charger and the application server. The charger updates the charger information stored in the charger with the change information at a predetermined update timing. The application server updates the total charger information stored on the application server with the change information at a predetermined update timing.

[0006] In such a system, if the update timing of the charger and the update timing of the application server differ, it is possible that the charger information obtained by the application server and the charger information stored in the charger may differ.

[0007] This disclosure is made to solve the above-mentioned problems, and its purpose is to provide a management system that suppresses discrepancies between the charger compatibility information stored on the application server and the charger information stored on the charger. [Means for solving the problem]

[0008] The management system relating to the first aspect of this disclosure comprises a communication terminal, a charger that operates based on charger information, and an application server that stores total charger information. The communication terminal has a display unit that displays total charger information obtained from the application server. The total charger information includes charger compatibility information corresponding to the charger information, and the charger information is updated at the update timing, which is the timing when the application server updates the charger compatibility information.

[0009] The charger included in the management system relating to the first aspect of this disclosure stores charger information, and the charger updates the charger information at the update timing.

[0010] The management system relating to the first aspect of this disclosure further comprises a management server for managing chargers, the management server transmits change information, which is part of the charger information, to the charger at the update timing, the charger stores the charger information and updates the charger information based on the change information.

[0011] The management system relating to the first aspect of this disclosure further comprises an information input terminal and a management server that manages chargers. The information input terminal transmits change information, which is part of the charger information, to the management server at the update timing. The management server transmits the change information to the charger. The charger stores the charger information and updates the charger information based on the change information.

[0012] The management system relating to the first aspect of this disclosure comprises an information input terminal, a management server for managing chargers, and an administrator terminal used by the administrator of the management server. The administrator terminal notifies the administrator of the update timing and transmits some of the charger information, including change information entered by the administrator, to the management server. The management server transmits the change information to the charger, and the charger possesses the charger information and updates the charger information based on the change information. [Effects of the Invention]

[0013] According to the management system described in this disclosure, it is possible to suppress discrepancies between the charger compatibility information stored on the application server and the charger information stored on the charger. [Brief explanation of the drawing]

[Figure 8] This is a control flow of the management system according to Modification 3 of this embodiment. [Modes for carrying out the invention]

[0015] Embodiments of this disclosure will be described in detail below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their descriptions will not be repeated. <Overall structure of the management system> Figure 1 is a diagram showing the schematic configuration of the management system according to this embodiment.

[0016] The management system 1 includes a plurality of chargers 2, an app server 30, a management server 40, an information input terminal 50, a communication terminal 60, and an administrator terminal 70. The app server 30, the management server 40, the information input terminal 50, and the administrator terminal 70 are connected to be communicable bidirectionally through a network NW. The plurality of chargers 2 and the management server 40 are connected to be communicable bidirectionally. The app server 30 and the communication terminal 60 are connected to be communicable bidirectionally.

[0017] The plurality of chargers 2 includes a first charger 10 and a second charger 20. Since the first charger 10 and the second charger 20 have substantially the same configuration, the first charger 10 will be described below.

[0018] The first charger 10 has a processor 11, a storage device 12, and a display device 13. The processor 11 includes, for example, a CPU (Central Processing Unit). The storage device 12 is a volatile memory such as a RAM (Random Access Memory). The display device 13 is a display such as an organic EL (Electro Luminescence) or a liquid crystal. A display not shown is configured to display various information according to a control command from the processor 11. Referring to FIG. 2, the storage device 12 stores first charger information 15, change information 99, and update timing information (not shown). The first charger information 15 is information such as an identification number of the first charger 10, output, charging unit price, business hours, etc. The change information 99 includes, together with the charger identification number, a part of the charger information excluding the charger identification number. In an embodiment of the present disclosure, the change information 99 is information related to the output of the first charger information 15. The update timing information is information on the timing when the app server 30 updates total charger information 34 described later. Referring to FIG. 1 again, the first charger 10 is driven based on the first charger information 15. The processor 11 updates the change information 99 to the first charger information 15 at an update timing based on the update timing information.

[0019] The application server 30 has a processor 31 and a storage device 32. The processor 31 includes, for example, a CPU (Central Processing Unit). The storage device 32 is a volatile memory such as a RAM (Random Access Memory). Referring to FIG. 3, the storage device 32 stores total charger information 34, change information 99, and update timing information (not shown). The total charger information 34 is a data table in which the charger information of each of the plurality of chargers 2 is centrally managed. The total charger information 34 includes, for example, first charger correspondence information 35 corresponding to the first charger information 15 shown in FIG. 2. The first charger correspondence information 35 is information such as output, charging unit price, business hours, etc. related to the first charger. That is, the first charger correspondence information 35 is substantially the same as the first charger information 15. The update timing information is information on the update timing when the application server 30 updates the change information 99 to the total charger information 34. Specifically, the update timing may be an arbitrary periodic date and time, or the timing when a predetermined number of accesses are made to the application server 30, etc. Referring to FIG. 1 again, the processor 31 updates the change information 99 to the total charger information 34 at the update timing based on the update timing information. In an embodiment of the present disclosure, the processor 31 of the application server 30 determines that the change information 99 is information related to the first charger 10. Based on this determination, the application server 30 updates the first charger correspondence information 35 in the total charger information 34 to the content of the change information 99.

[0020] The management server 40 has a processor 41 and a storage device 42. The processor 41 includes, for example, a CPU (Central Processing Unit). The storage device 12 is a volatile memory such as a RAM (Random Access Memory). The storage device stores the change information 99 shown in FIG. 2 and the update timing information. The management server 40 acquires the change information 99 from the information input terminal 50. The processor 41 determines, for example, based on the data of the change information 99 that the change information 99 is information related to the first charger information 15. The management server 40 transmits the change information 99 to the first charger 10.

[0021] The information input terminal 50 includes a processor 51, a storage device 52, an input device 53, and a display device 54. The processor 51 includes, for example, a CPU (Central Processing Unit). The storage device 52 is volatile memory such as RAM (Random Access Memory). The input device 53 receives signals generated by operations from the administrator of the management server 40. The administrator of the management server 40 can input predetermined instructions or requests to the input device 53. The input device 53 may be a touch panel, or in place of or in addition to a touch panel, various switches, various pointing devices, or a keyboard. The display device 54 is, for example, a display that outputs various information (such as processing results) to the operator. In the embodiment of this disclosure, the administrator of the management server 40 inputs change information 99 to the information input terminal 50 through the input device 53. The change information 99 is stored in the storage device 52. The information input terminal 50 transmits the change information 99 to the application server 30 and the management server 40.

[0022] The communication terminal 60 is, for example, a terminal owned by a user of an electric vehicle that can be charged by the first charger 10. The communication terminal 60 has a display unit 61. The communication terminal 60 has application software that can communicate with the application server 30. The user of the electric vehicle obtains total charger information 34 stored in the application server 30 through the communication terminal 60. The total charger information 34 is displayed on the display unit of the communication terminal 60. Based on the total charger information 34 displayed on the display unit of the communication terminal 60, the user of the electric vehicle selects a charger to use from among multiple chargers 2.

[0023] The administrator terminal 70 is, for example, a terminal owned by the administrator of the management server 40. The administrator terminal 70 has a display screen and a speaker (not shown). The administrator terminal 70 is configured to notify the administrator of the management server 40 of the update timing based on the update timing information. Note that the information input terminal 50 may also include the functions of the administrator terminal 70. <Control flow of the management system> Next, with reference to Figures 4 and 5, the control flow of the management system executed by the management system will be described.

[0024] In step S10 shown in Figure 4, the information input terminal 50 checks whether change information 99 has been entered. The input of change information 99 is done by the administrator of the management server 40 entering the content of change information 99 through the input device 53 of the information input terminal 50. In this embodiment of the disclosure, an example is shown in which the administrator of the management server 40 enters the content of change information 99 as shown in Figure 2. If change information 99 has been entered (Yes in step S10), the information input terminal 50 stores the change information 99 in the storage device 52, and the processing of the information input terminal 50 proceeds to step S20. If change information 99 has not been entered (No in step S10), the information input terminal 50 processes step S10 again.

[0025] In step S20, the information input terminal 50 sends change information 99 to the application server 30 and the management server 40. After that, the information input terminal 50 terminates processing by the management system 1.

[0026] In step S30, the management server 40 checks whether it has received change information 99. If it has received change information 99 (Yes in step S30), the management server 40 stores the change information 99 in the storage device 42, and the management server 40 proceeds to step S40. If it has not received change information 99 (No in step S30), the management server 40 processes step S30 again.

[0027] In step S40, the management server 40 requests the application server 30 to send update timing information. After that, the management server 40 proceeds to step S90.

[0028] In step S49, the application server 30 checks whether it has received change information 99. If it has received change information 99 (Yes in step S49), it stores the change information 99 in the application server 30's storage device 32, and the application server 30 proceeds to step S50. If it has not received change information 99 (No in step S49), the application server 30 processes step S49 again.

[0029] In step S50, the application server 30 checks if there is a request to send update timing information. If there is a request to send update timing information (Yes in step S50), the application server 30 proceeds to step S60. If there is no request to send update timing information (No in step S50), the application server 30 processes step S50 again.

[0030] In step S60, the application server 30 sends update timing information to the management server 40. After that, the application server 30 proceeds to step S70.

[0031] In step S70, the application server 30 checks whether the update timing based on the update timing information has elapsed. If the update timing has elapsed (Yes in step S70), the application server 30 proceeds to step S80. If the update timing has not elapsed (No in step S70), the application server 30 processes step S70 again.

[0032] In step S80, the application server 30 updates the first charger compatibility information 35. More specifically, in step S49, the application server 30 stores the change information 99 in the storage device 32. When the update timing has elapsed, the processor 31 of the application server 30 updates the total charger information 34 based on the change information 99 stored in the storage device 32. More specifically, in this embodiment of the disclosure, the change information 99 is information about the first charger 10. Therefore, the processor 31 updates the first charger compatibility information 35 of the total charger information 34 with the content of the change information 99. As a result, the content of the first charger compatibility information 35 becomes the updated content of the first charger compatibility information 35 shown in Figure 3. After that, the application server 30 proceeds to step S230.

[0033] In step S90, the management server 40 checks whether it has received update timing information. If it has received update timing information (Yes in step S90), the management server 40 stores the update timing information in the storage device 42, and the management server 40 proceeds to step S100. If it has not received update timing information (No in step S90), the management server 40 processes step S90 again.

[0034] In step S100, the management server 40 transmits the change information 99 and the update timing information to the first charger 10. More specifically, in the embodiments of this disclosure, the processor 41 of the management server 40 determines that the change information 99 is information relating to the first charger 10. Based on this determination, the management server 40 transmits the change information 99 and the update timing information to the first charger 10. After that, the management server 40 terminates processing of the management system 1.

[0035] In step S110, the first charger 10 confirms that it has received change information 99. If it has received change information 99 (Yes in step S110), the first charger 10 stores the change information 99 in the storage device 12, and the processing of the first charger 10 proceeds to step S120. If it has not received change information 99 (No in step S110), the first charger 10 processes step S110 again.

[0036] In step S120, the first charger 10 checks whether it has received update timing information. If it has received update timing information (Yes in step S120), the first charger 10 stores the update timing information in the storage device 12, and the processing of the first charger 10 proceeds to step S130. If it has not received update timing information (No in step S120), the first charger 10 processes step S120 again.

[0037] In step S130, the first charger 10 checks whether the update timing based on the update timing information has elapsed. If the update timing has elapsed (Yes in step S130), the first charger 10 proceeds to step S140. If the update timing has not elapsed (No in step S130), the first charger 10 processes step S130 again.

[0038] In step S140, the first charger 10 updates the first charger information 15. More specifically, when the update timing has elapsed, the processor 11 of the first charger 10 updates the first charger information 15 stored in the storage device 12 based on the change information 99 stored in the storage device 12. As a result, the content of the first charger information 15 becomes the updated content of the first charger information 15 shown in Figure 2. After that, the processing of the first charger 10 proceeds to step S270.

[0039] Referring to Figure 5, in step S210, the communication terminal 60 checks if there is a request to acquire total charger information 34. Here, a request to acquire total charger information 34 is made, for example, by the user of the communication terminal 60 launching application software installed on the communication terminal 60 to acquire total charger information 34. Alternatively, it may be made by the user of the communication terminal 60 accessing a website to view total charger information 34. If there is a request to acquire total charger information 34 (Yes in step S210), the communication terminal 60 proceeds to step S220. If there is no request to acquire total charger information 34 (No in step S210), the communication terminal 60 processes step S210 again.

[0040] In step S220, the communication terminal 60 requests the application server 30 to send the total charger information 34. After that, the communication terminal 60 proceeds to step S250.

[0041] In step S230, the application server 30 checks if there is a request to send total charger information 34. If there is a request to send total charger information 34 (Yes in step S230), the application server 30 proceeds to step S240. If there is no request to send total charger information 34 (No in step S230), the application server 30 processes step S230 again.

[0042] In step S240, the application server 30 sends total charger information 34 to the communication terminal 60. After that, the application server 30 terminates the processing of the management system 1.

[0043] In step S250, the communication terminal 60 checks whether it has received the total charger information 34. If it has received the total charger information 34 (Yes in step S250), the communication terminal 60 proceeds to step S260. If it has not received the total charger information 34 (No in step S250), the communication terminal 60 processes step S250 again.

[0044] In step S260, the communication terminal 60 displays the total charger information 34 on its display unit 61. After that, the communication terminal 60 terminates the processing of the management system 1.

[0045] In step S270, the first charger 10 checks if there is a request to display the first charger information 15. Here, a request to display the first charger information 15 is made, for example, by a user of the first charger 10 touching the display device 13 of the first charger 10. Before charging an electric vehicle using the first charger 10, the user of the first charger 10 checks the first charger information 15 displayed on the display device 13 and decides whether or not to use the first charger 10. If there is a request to display the first charger information 15 (Yes in step S270), the processing of the first charger 10 proceeds to step S280. If there is no request to display the first charger information 15 (No in step S270), the first charger 10 processes step S270 again.

[0046] In step S280, the first charger 10 displays the first charger information 15 on the display device 13. After that, the first charger 10 terminates the processing of the management system 1.

[0047] In the above embodiment, the application server 30 updates the change information 99 to the first charger compatibility information 35 at the update timing based on the update timing information. The first charger 10 updates the change information 99 to the first charger information 15 at the update timing based on the update timing information obtained from the application server 30. As a result, the contents of the change information 99 are updated to both the first charger information 15 and the first charger compatibility information 35 at the same time. Consequently, it is possible to suppress discrepancies between the contents of the first charger compatibility information 35 stored in the application server 30 and the first charger information 15 stored in the first charger 10.

[0048] In this disclosure, “same timing” includes cases where the date and time are exactly the same, and cases where the date and time are substantially the same. In other words, in this disclosure, substantially the same means that there may be some errors due to the processing speed of the processor or the processing path from the time the update timing has elapsed until the update of the change information 99. <Example 1> In embodiments of this disclosure, an example is shown in which the first charger 10 suspends the progress of the management system 1 until the update timing, but this disclosure is not limited thereto. For example, the management server 40 may suspend the progress of the management system 1 until the update timing.

[0049] Figure 6 shows the control flow of the management system 1 according to the modified embodiment 1. Note that each process from step S10 to step S90 is the same as each process from step S10 to step S90 described in Figure 4, so the explanation is omitted.

[0050] In step S95, the management server 40 checks whether the update timing based on the update timing information has elapsed. If the update timing has elapsed (Yes in step S95), the management server 40 proceeds to step S96. If the update timing has not elapsed (No in step S95), the management server 40 processes step S95 again.

[0051] In step S96, the management server 40 sends change information 99 to the first charger 10. More specifically, the processor 41 of the management server 40 determines that the change information 99 is information relating to the first charger 10. Based on this determination, the management server 40 sends the change information 99 to the first charger 10. After that, the management server 40 terminates processing of the management system 1.

[0052] In step S111, the first charger 10 confirms that it has received change information 99. If it has received change information 99 (Yes in step S111), the first charger 10 stores the change information 99 in the storage device 12, and the processing of the first charger 10 proceeds to step S141. If it has not received change information 99 (No in step S111), the first charger 10 processes step S111 again.

[0053] In step S141, the first charger 10 updates the first charger information 15. More specifically, as soon as the processor 11 of the first charger 10 determines that it has received change information 99 in step S111, it updates the first charger information 15 based on the change information 99 in step S141. After that, the processing of the first charger 10 proceeds to step S270.

[0054] Here, the processing after step S80 in the second charger 20 and the processing after step S141 in the first charger 10 are described in Figure 5 above, so their explanation is omitted.

[0055] In the above embodiment, the application server 30 updates the change information 99 to the first charger compatibility information 35 at the update timing based on the update timing information. The management server 40 transmits the change information 99 to the first charger 10 at the update timing based on the update timing information obtained from the application server 30. Immediately after receiving the change information 99, the first charger 10 updates the change information 99 to the first charger information 15. As a result, the contents of the change information 99 are updated to both the first charger information 15 and the first charger compatibility information 35 at the same time. Consequently, it is possible to suppress discrepancies between the contents of the first charger compatibility information 35 stored in the application server 30 and the first charger information 15 stored in the first charger 10. <Modification 2> In embodiments of this disclosure, the information input terminal 50 may further suspend the flow of the management system 1 until the update timing.

[0056] Figure 7 shows the control flow of the management system 1 according to the modified embodiment 2. Note that the processing of step S10 is the same as step S10 in Figure 4 described above, so the explanation is omitted.

[0057] In step S21, the information input terminal 50 sends change information 99 to the application server 30 and requests the application server 30 to send update timing information. After that, the information input terminal 50 proceeds to step S90.

[0058] Since the processes from step S49 to step S90 are the same as those described in Figure 4, their explanation will be omitted.

[0059] In step S91, the information input terminal 50 checks whether the update timing based on the update timing information has elapsed. If the update timing has elapsed (Yes in step S91), the information input terminal 50 proceeds to step S92. If the update timing has not elapsed (No in step S91), the information input terminal 50 processes step S91 again.

[0060] In step S92, the information input terminal 50 sends the change information 99 to the management server 40. After that, the information input terminal 50 terminates the processing of the management system 1.

[0061] In step S93, the management server 40 checks whether it has received change information 99. If it has received change information 99 (Yes in step S93), the management server 40 stores the change information 99 in the storage device 42, and the management server 40 proceeds to step S96. If it has not received change information 99 (No in step S93), the management server 40 processes step S93 again.

[0062] In step S96, the management server 40 sends change information 99 to the first charger 10. More specifically, the processor 41 of the management server 40 determines that the change information 99 is information relating to the first charger 10. Based on this determination, the management server 40 sends the change information 99 to the first charger 10. After that, the management server 40 terminates processing of the management system 1.

[0063] After step S96, the first charger 10 processes steps S111 and S141. The processing of steps S111 and S141 in the first charger 10 is the same as the processing of steps S111 and S141 in Figure 6 described above, so the explanation is omitted. Also, the processing after step S80 in the application server 30 and the processing after step S141 in the first charger 10 follow Figure 5 described above, so the explanation is omitted.

[0064] In the above embodiment, the application server 30 updates the change information 99 to the first charger compatibility information 35 at the update timing based on the update timing information. The information input terminal 50 transmits the change information 99 to the management server 40 at the update timing based on the update timing information obtained from the application server 30. Immediately after receiving the change information 99, the management server 40 transmits the change information 99 to the first charger 10. Immediately after receiving the change information 99, the first charger 10 updates the change information 99 to the first charger information 15. As a result, the contents of the change information 99 are updated to the first charger information 15 and the first charger compatibility information 35 at the same time. Consequently, it is possible to suppress discrepancies between the contents of the first charger compatibility information 35 stored in the application server 30 and the first charger information 15 stored in the first charger 10. <Variation 3> In embodiments of this disclosure, the administrator of the management server 40 may further withhold input of change information 99 to the information input terminal 50 until the update timing. More specifically, the administrator terminal 70 notifies the administrator of the management server 40 of the update timing, so that the administrator of the management server 40 withholds input of change information 99 until immediately before the update timing.

[0065] Figure 8 shows the control flow of the management system 1 according to the third modified embodiment. In step S1, the management server 40 requests the application server 30 to send update timing information. Subsequently, the management server 40 proceeds to step S4.

[0066] In step S2, the application server 30 checks if there is a request to send update timing information. If there is a request to send update timing information (Yes in step S2), the application server 30 proceeds to step S3. If there is no request to send update timing information (No in step S2), the application server 30 processes step S2 again.

[0067] In step S3, the application server 30 sends update timing information to the management server 40. After that, the application server 30 proceeds to step S70.

[0068] In step S4, the management server 40 checks whether it has received update timing information. If it has received update timing information (Yes in step S4), the management server 40 stores the update timing information in the storage device 42, and the management server 40 proceeds to step S5. If it has not received update timing information (No in step S4), the management server 40 processes step S4 again.

[0069] In step S5, the management server 40 sends update timing information to the administrator terminal 70. After that, the management server 40 proceeds to step S93.

[0070] In step S6, the administrator terminal 70 checks whether it has received update timing information. If it has received update timing information (Yes in step S6), the administrator terminal 70 proceeds to step S7. If it has not received update timing information (No in step S6), the administrator terminal 70 processes step S6 again.

[0071] In step S7, the administrator terminal 70 notifies the administrator of the management server 40, which has the administrator terminal 70, of the update timing based on the update timing information. The notification of the update timing is made before the update timing. Based on the update timing notified from the administrator terminal 70, the administrator of the management server 40 adjusts the timing of inputting the change information 99 to the information input terminal 50.

[0072] In step S11, the information input terminal 50 checks if there is change information 99. If there is change information 99 (Yes in step S11), the information input terminal 50 proceeds to step S20. If there is no change information 99 (No in step S11), the information input terminal 50 processes step S11 again.

[0073] In step S20, the information input terminal 50 sends change information 99 to the application server 30 and the management server 40. After that, the information input terminal 50 terminates processing by the management system 1.

[0074] In step S49, the application server 30 checks whether it has received change information 99. If it has received change information 99 (Yes in step S49), it stores the change information 99 in the application server 30's storage device 32, and the application server 30 proceeds to step S70. If it has not received change information 99 (No in step S49), the application server 30 processes step S49 again.

[0075] After step S49, the application server 30 processes steps S70 and S80. The processing of steps S70 and S80 by the application server 30 is the same as the processing of steps S70 and S80 in Figure 4 described above, so the explanation is omitted.

[0076] Furthermore, the processes from step S93 to step S141 are identical to those described in Figure 7, so their explanation is omitted. Also, the processes after step S80 in the application server 30 and after step S141 in the first charger 10 follow the above-mentioned Figure 5, so their explanation is omitted.

[0077] In the above embodiment, the administrator terminal 70 notifies the administrator of the management server 40 of the update timing based on the update timing information. The administrator of the management server 40 inputs change information 99 into the information input terminal 50 based on the update timing. Immediately after inputting the change information 99, the information input terminal 50 transmits the change information 99 to the application server 30 and the management server 40. The application server 30 updates the change information 99 to the first charger compatibility information 35 at the update timing based on the update timing information. Immediately after receiving the change information 99, the management server 40 transmits the change information 99 to the first charger 10. Immediately after receiving the change information 99, the first charger 10 updates the change information 99 to the first charger information 15. If the administrator of the management server 40 inputs the change information 99 into the information input terminal 50 immediately before the update timing, the contents of the change information 99 are updated to the first charger information 15 and the first charger compatibility information 35 at the same time. As a result, it is possible to suppress discrepancies between the contents of the first charger compatibility information 35 stored in the application server 30 and the first charger information 15 stored in the first charger 10.

[0078] Furthermore, the management server 40 may include the functions of the administrator terminal 70, and the management server 40 may notify the administrator of the management server 40 of the update timing.

[0079] In the above embodiment, an example was shown in which the first charger 10 has a processor 11 and a storage device 12, but this disclosure is not limited thereto. For example, the functions of the processor 11 and storage device 12 of the first charger 10 may be implemented on the cloud. The same applies to the application server 30, the management server 40 and the information input terminal 50.

[0080] In the above embodiment, an example was shown in which the first charger 10 is driven based on first charger information 15 stored in the storage device 12, but the disclosure is not limited thereto. The first charger 10 may also be driven based on first charger information 15 stored in the management server 40 by requesting the management server 40 to transmit the first charger information 15 each time it is driven.

[0081] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of this disclosure is indicated by the claims rather than by the description of the embodiments above, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
