DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. <Configuration of Operation Status Output System 1> FIG. 1 is a diagram showing an example of the overall configuration of an operation status output system 1 to which this embodiment is applied. The operation status output system 1 is a system that enables the provision of a service (hereinafter referred to as "this service") that enables the operation status of an EV charger to be grasped even when a non-electric vehicle can be parked in a parking space where an EV charger is installed.

[0010] Here, an "EV charger" refers to a charger that supplies power to electric vehicles parked in each parking space in a parking lot, enabling them to be charged. A "parking space" refers to an area in a parking lot, demarcated by a white line or other marking, that can accommodate one vehicle. A parking lot may have one or more parking spaces. An "electric vehicle" refers to a vehicle that charges with supplied power and can run using the charged power. A "non-electric vehicle" refers to a vehicle other than an electric vehicle. Specifically, a non-electric vehicle refers to a vehicle that can run using fuel such as gasoline or gas and does not require charging. For this reason, for example, so-called hybrid vehicles that can run using a combination of fuel and electricity but do not require charging using an EV charger are classified as non-electric vehicles.

[0011] The operating status output system 1 is configured by connecting a management server 10, sensor units 30-1 to 30-n (n is an integer value of 1 or greater), and user terminals 70-1 to 70-m (m is an integer value of 1 or greater) via a network 90. ​​The network 90 is, for example, a local area network (LAN) or the Internet. Furthermore, EV chargers 50-1 to 50-n are connected to the sensor units 30-1 to 30-n, respectively, by wire or wirelessly.

[0012] Hereinafter, when there is no need to explain each of the sensor units 30-1 to 30-n individually, they will be collectively referred to as "sensor unit 30." Furthermore, when there is no need to explain each of the EV chargers 50-1 to 50-n individually, they will be collectively referred to as "EV charger 50." Furthermore, when there is no need to explain each of the user terminals 70-1 to 70-m individually, they will be collectively referred to as "user terminal 70." Specific examples of the service provided by the operating status output system 1 will be described later with reference to FIG. 8.

[0013] [Management Server 10] The management server 10 is an information processing device that serves as a server that manages the entire operation status output system 1. The management server 10 is managed, for example, by a party that provides this service. The management server 10 transmits various types of information to the sensor units 30, the user terminals 70, and external devices, and enables various processes to be executed. The management server 10 also acquires various types of information transmitted from the sensor units 30, the user terminals 70, and external devices, and enables various processes to be executed.

[0014] For example, the management server 10 acquires information transmitted from a sensor unit 30 that detects the presence or absence of a vehicle in each predetermined parking space in the parking lot. In addition, as a second detection means, the management server 10 detects the presence or absence of charging by an EV charger 50 to a vehicle parked in each predetermined parking space in the parking lot.

[0015] Specifically, the management server 10 detects "whether charging has occurred using the EV charger 50" based on the detection results of the presence or absence of a vehicle in each parking space provided by the sensor units 30 and information about charging using the EV charger 50. The information about charging using the EV charger 50 includes information about the history of whether charging has occurred using the EV charger 50 (hereinafter referred to as "charging history information"). The charging history information also includes the date and time when charging using the EV charger 50 was performed and the date and time when charging using the EV charger 50 was not performed.

[0016] The management server 10 also manages the results of detection of the presence or absence of a vehicle in each parking space and the results of detection of the presence or absence of charging by the EV charger 50 for each parking space, in association with each other, for a predetermined period of time. Here, the "predetermined period" is defined, for example, by seconds, minutes, hours, days, weeks, months, quarters, or years. The management server 10 is also capable of outputting this associated information.

[0017] Furthermore, the management server 10 is capable of calculating the usage record for each parking space over a predetermined period based on the detection results of whether or not a vehicle is present in each parking space. When calculating the usage record for each parking space, the management server 10 is capable of calculating the parking time as the usage record. Furthermore, the management server 10 is capable of calculating the charging record for each parking space over a predetermined period based on the detection results of whether or not charging is being performed by the EV charger 50 in each parking space. When calculating the charging record for each parking space, the management server 10 is capable of calculating the charging time as the charging record.

[0018] Furthermore, the management server 10 is capable of outputting the operation status of the EV charger 50 for each parking space based on the calculated usage history and charging history. When outputting the operation status of the EV charger 50 for each parking space, the management server 10 is capable of outputting information based on the difference between the parking time as the usage history and the charging time as the charging history as the operation status of the EV charger 50. Here, the information based on the difference between the parking time and the charging time may be, for example, the operation rate of the EV charger 50, calculated as the ratio of the charging time to the parking time.

[0019] Furthermore, the management server 10 calculates the running revenue that can be continuously obtained by allowing drivers who park their electric vehicles in the parking space to use the EV charger 50, based on the operating status of the EV charger 50. Furthermore, the management server 10 calculates the running costs required to operate the EV charger 50, based on the operating status of the EV charger 50. The management server 10 makes it possible to output income and expenditure information based on the initial costs required to install the EV charger 50 and the calculated running revenue and running costs.

[0020] The income and expenditure information output by management server 10 may include information relating to a prediction of the period required to recover the initial cost (hereinafter referred to as "recovery prediction information"). When outputting income and expenditure information including recovery prediction information, management server 10 groups days with similar usage environments, assuming the ratio of charging time to parking time to be the operation rate of EV chargers 50, and outputs income and expenditure information including recovery prediction information that takes into account the operation rate of EV chargers 50 in each group. Management server 10 also outputs income and expenditure information including recovery prediction information that takes into account the unit price of running revenue. The configuration and processing of management server 10 will be described in detail below.

[0021] [Sensor unit 30] The sensor unit 30 is a device installed in each parking space, and serves as a first detection means for detecting the presence or absence of a vehicle in the parking space at predetermined times and transmitting the detection results. The sensor unit 30 is composed of various sensors, communication means, etc. The hardware configuration of the sensor unit 30 will be described later with reference to FIG. 3.

[0022] The sensor unit 30 may be configured to transmit all of the detection results of the presence or absence of a vehicle in a parking space for each predetermined time period, or may be configured to transmit only the detection results that have changed in state. In this case, only the information necessary for the management server 10 to detect the presence or absence of charging is transmitted, thereby reducing the burden on the system.

[0023] [EV charger 50] The EV charger 50 is a device installed in each parking space in a parking lot, and is a charger that enables charging of electric vehicles parked in the parking space. Information related to charging by the EV charger 50 is transmitted to the management server 10 via the sensor unit 30 connected to the EV charger 50.

[0024] [User terminal 70] The user terminal 70 is an information processing device such as a smartphone, tablet terminal, or personal computer operated by a user who uses the operation status output system 1 as a user of the present service. Application software that enables the use of the present service is installed on the user terminal 70. Examples of users of the present service include parking lot owners, providers of EV chargers 50 to parking lots, and users of the parking lots.

[0025] The user terminal 70 is capable of transmitting various types of information to both the management server 10 and external devices. The user terminal 70 is also capable of acquiring various types of information transmitted from both the management server 10 and external devices and executing various processes. For example, the user terminal 70 acquires information such as income and expenditure information transmitted from the management server 10 and displays it on a display or the like.

[0026] The configuration of the operation status output system 1 described above is one example, and it is sufficient if the operation status output system 1 as a whole has the functions to realize the above-mentioned processing. Therefore, some or all of the functions to realize the above-mentioned processing may be shared or cooperated within the operation status output system 1. That is, some or all of the functions of the management server 10 constituting the operation status output system 1 may be functions of other devices. Also, some or all of the functions of other devices may be functions of the management server 10. Furthermore, some or all of the functions of the management server 10 and other devices constituting the operation status output system 1 may be transferred to other servers, etc. (not shown). This promotes processing by the operation status output system 1 as a whole and also enables processes to be complemented by each other.

[0027] <Hardware configuration> [Hardware configuration of management server 10] FIG. 2 is a diagram showing an example of the hardware configuration of the management server 10 that constitutes the operation status output system 1 of FIG. The management server 10 has a control unit 11, a memory 12, a storage unit 13, a communication unit 14, an operation unit 15, and a display unit 16. These units are connected by a data bus, an address bus, a PCI (Peripheral Component Interconnect) bus, etc.

[0028] The control unit 11 is a processor that controls the functions of the management server 10 through the execution of various software such as an OS (operating system) and application software. In this embodiment, various processes are executed by an arbitrary computer. The arbitrary computer may be realized as a processor in the form of hardware, a program in the form of software, or a combination thereof. The arbitrary computer may be a general-purpose computer, a computer for a specific application, a workstation, or any other system capable of executing various processes.

[0029] The processor is configured to execute various processes in cooperation with the program. The processor can function as each unit or each means in this embodiment. The order in which the processor executes processes is not limited to the order described in this embodiment and can be changed as necessary.

[0030] The processor can be configured with one or more pieces of hardware. The type of hardware that configures the processor is not limited to a specific type. For example, the processor may be a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a programmable logic device such as an FPGA (Field Programmable Gate Array), a dedicated circuit for executing specific processing such as an ASIC (Application Specific Integrated Circuit), a GPU (Graphic Processing Unit), an NPU (Neural Processing Unit), or other hardware.

[0031] A processor is not limited to a combination of multiple pieces of the same type of hardware, but can also be configured with a combination of multiple pieces of different types of hardware. When multiple pieces of hardware are configured to execute one or more processes of a certain processor, the multiple pieces of hardware may exist in devices physically separated from each other, or may exist in the same device. The hardware is configured with an electric circuit (circuitry) that combines circuit elements such as semiconductor elements.

[0032] In any of the embodiments, the order in which various processes are executed by the processor is not limited to the order described in each embodiment and can be changed as necessary. The program may be firmware or software such as microcode. The program may be, for example, a group of program modules. Each function constituting the group of program modules may be realized by a processor configured to execute each function. The program in each of the embodiments may be program code or multiple code segments stored in one or more non-transitory computer-readable media (e.g., semiconductor memory, magnetic or optical storage medium, or other storage).

[0033] The program may be stored in multiple non-transitory computer-readable media that are physically separate from each other. The program code or multiple code segments may be represented by any combination of procedures, functions, subprograms, routines, subroutines, modules, software packages, classes, instructions, data structures, and program statements. The program code or multiple code segments may be connected to other code segments or hardware circuits by sending or receiving information, data, arguments, parameters, or memory contents.

[0034] The memory 12 is a storage area for storing various software programs and data used for executing the software programs, and is used as a work area for calculations. The memory 12 is configured, for example, by RAM (Random Access Memory).

[0035] The storage unit 13 is a storage area that stores input data for various software programs and output data from various software programs. The storage unit 13 is composed of, for example, a hard disk drive (HDD), a solid state drive (SSD), or semiconductor memory used to store programs and various setting data. The storage unit 13 is provided with a database for storing various types of information. The database provided in the storage unit 13 stores various types of information, such as the results of detecting the presence or absence of a vehicle in each parking space, information about charging by the EV charger 50, the results of detecting the presence or absence of charging by the EV charger 50 in each parking space, and calculated balance information.

[0036] The communication unit 14 transmits and receives data between the sensor unit 30, the EV charger 50, and the outside world via the network 90. ​​The operation unit 15 is composed of, for example, a keyboard, a mouse, mechanical buttons, and switches, and accepts input operations.

[0037] The operation unit 15 also includes a touch sensor that forms a touch panel integrally with the display unit 16. The display unit 16 is configured, for example, with a liquid crystal display or an organic EL (Electro Luminescence) display used to display information, and displays images, text data, etc. The display unit 16 displays a user interface, etc.

[0038] [Hardware configuration of sensor unit 30] FIG. 3 is a diagram showing an example of the hardware configuration of the sensor unit 30 that constitutes the operation status output system 1 of FIG. FIG. 4 is a diagram showing an example of the external configuration of the sensor unit 30. As shown in FIG. 3, the sensor unit 30 includes a control unit 31, a memory 32, a storage unit 33, a communication unit 34, an operation unit 35, and a display unit 36, which correspond to the control unit 11, memory 12, storage unit 13, communication unit 14, operation unit 15, and display unit 16 shown in FIG. 2. In addition to these components, the sensor unit 30 also includes a sensor unit 37 made up of various sensors. The sensor unit 37 includes a distance measurement sensor that can detect the presence or absence of a vehicle in a parking space from the measurement results of the distance to the vehicle, an image sensor that can detect the presence or absence of a vehicle in a parking space from a captured image of the parking space, and the like.

[0039] For example, as shown in FIG. 4, the sensor unit 30 may have a box-shaped housing 300 and a sensor unit 37 at the tip of a cable 301 extending from the housing 300. In this case, the control unit 31, memory 32, storage unit 33, communication unit 34, operation unit 35, and display unit 36 ​​shown in FIG. 3 are arranged in the space inside the housing 300. The sensor unit 30 may be installed, for example, by fixing the housing 300 and sensor unit 37 to a columnar structure erected for each parking space, or by fixing the housing 300 and sensor unit 37 to an EV charger 50 installed for each parking space. A specific installation mode of the sensor unit 30 will be described later with reference to FIG. 5.

[0040] [Hardware Configuration of EV Charger 50 and User Terminal 70] EV charger 50 and user terminal 70 each include a control unit, memory, storage unit, communication unit, operation unit, and display unit corresponding to control unit 11, memory 12, storage unit 13, communication unit 14, operation unit 15, and display unit 16 shown in Fig. 2. A specific installation mode of EV charger 50 will be described later with reference to Fig. 5.

[0041] <Functional configuration> [Functional Configuration of the Control Unit 11 of the Management Server 10] FIG. 5 is a diagram illustrating an example of the functional configuration of the control unit 11 of the management server 10 of FIG. The control unit 11 of the management server 10 functions as an acquisition unit 111 that acquires various types of information, and a management unit 112 that manages the various types of information. The control unit 11 also functions as a detection unit 113 that detects whether or not charging is being performed by the EV charger 50 for each parking space, and an association unit 114 that associates the detection result of the presence or absence of a vehicle with the detection result of the presence or absence of charging. The control unit 11 also functions as a usage record calculation unit 115 that calculates the usage record of parking spaces in the parking lot, a charging record calculation unit 116 that calculates the charging record for each parking space, and an output control unit 117 that controls the transmission of various types of information. The control unit 11 also functions as a revenue calculation unit 118 that calculates the revenue of the EV charger, and a cost calculation unit 119 that calculates the costs required to operate the EV charger.

[0042] The acquisition unit 111 acquires various types of information transmitted from the sensor unit 30 and external sources via the communication unit 14 (see FIG. 2). For example, the acquisition unit 111 acquires the detection results of the presence or absence of a vehicle in each parking space transmitted from the sensor unit 30. The acquisition unit 111 also acquires information related to charging by the EV charger 50 transmitted from the sensor unit 30.

[0043] The management unit 112 stores and manages various types of information in a database in the storage unit 13 (see FIG. 2). For example, the management unit 112 stores and manages the detection results of the presence or absence of a vehicle in each parking space and information related to charging by the EV charger 50, which are acquired by the acquisition unit 111, in the database. The management unit 112 also stores and manages the detection results of the presence or absence of charging by the EV charger 50 in each parking space, which are detected by the detection unit 113, which will be described later, in the database. The management unit 112 also stores and manages the calculation results of the usage record calculation unit 115, charging record calculation unit 116, revenue calculation unit 118, and cost calculation unit 119, which will be described later, in the database.

[0044] The detection unit 113 detects whether or not a vehicle parked in each predetermined parking space in the parking lot is being charged by the EV charger 50. Specifically, the detection unit 113 detects whether or not a vehicle parked in each predetermined parking space is being charged by the EV charger 50 based on the detection result of the presence or absence of a vehicle in each parking space and information related to charging by the EV charger 50, both acquired by the acquisition unit 111. For example, the detection unit 113 detects whether or not a vehicle parked in each predetermined parking space is being charged by the EV charger 50 based on the detection result of the presence or absence of a vehicle and the date and time of charging identified from charging history information included in the information related to charging.

[0045] The association unit 114 associates the detection result of whether or not a vehicle is present in each parking space during a predetermined period with the detection result of whether or not charging is occurring in each parking space by the EV charger 50. These two types of detection results associated by the association unit 114 are managed by the management unit 112.

[0046] The usage record calculation unit 115 calculates the usage record for each parking section during a predetermined period based on the detection result of the presence or absence of a vehicle in each parking section acquired by the acquisition unit 111. Specifically, for example, the usage record calculation unit 115 calculates the parking time as the usage record for each parking section.

[0047] The charging result calculation unit 116 calculates the charging result for each parking space in a predetermined period based on the detection result of whether or not charging has occurred for each parking space by the detection unit 113. Specifically, for example, the charging result calculation unit 116 calculates the charging time as the charging result for each parking space.

[0048] The output control unit 117 controls the output of various types of information. For example, the output control unit 117 controls the output of information that associates the detection result of the presence or absence of a vehicle in each parking space with the detection result of the presence or absence of charging by the EV charger 50 in each parking space, both of which are managed by the management unit 112. The output control unit 117 also controls the output of the usage history for each parking space calculated by the usage history calculation unit 115. The output control unit 117 also controls the output of the charging history for each parking space calculated by the charging history calculation unit 116.

[0049] Furthermore, the output control unit 117 controls the output of the operation status of the EV charger 50 based on the calculated usage record and charging record for each parking space. Specifically, for example, the output control unit 117 outputs information based on the difference between the parking time as the usage record and the charging time as the charging record as the operation status of the EV charger 50. Here, the information based on the difference between the parking time and the charging time is, for example, the operation rate of the EV charger 50.

[0050] Furthermore, the output control unit 117 controls the output of income and expenditure information based on the running revenue calculated by the revenue calculation unit 118 (described later), the running expenses calculated by the expense calculation unit 119 (described later), and the initial expenses required for installing the EV charger 50. Specifically, for example, the output control unit 117 controls the output of recovery prediction information as the income and expenditure information. In this case, the recovery prediction information to be output is, for example, recovery prediction information that takes into account the operation rates of the EV charger 50 on weekdays and on holidays, or recovery prediction information that takes into account the unit price of the running revenue. The initial expenses required for installing the EV charger 50 are managed by the management unit 112.

[0051] This service is applicable to a business model in which the provider of EV charger 50 installs EV charger 50 in a parking lot, and then recovers the costs from the running profits obtained from EV charger 50 without charging the owner of the parking lot for the installation costs. In such a business model, in order to increase the convenience of those who use the parking lot (car drivers) or to increase the turnover rate of the parking lot, non-electric vehicles may be allowed to park in the parking space where EV charger 50 is installed.

[0052] However, if an increasing number of non-electric vehicles are parked in a parking space where an EV charger 50 is installed, the running revenue obtained from the EV charger 50 will decrease, and there is a risk that cost recovery will no longer be possible. In response to this, the income and expenditure information output under the control of the output control unit 117 includes recovery forecast information, so the provider of the EV charger 50, who is the user of this service, can grasp the prospects for cost recovery.

[0053] In addition, the output control unit 117 controls the output of information regarding the usage status of the parking spaces, which is identified or estimated from information that correlates the detection results of the presence or absence of a vehicle in each parking space with the detection results of the presence or absence of charging by the EV charger 50 in each parking space.

[0054] Information about the parking space usage status includes, for example, when and for how long an electric vehicle was parked, whether it was charged by the EV charger 50 during that time, and if it was charged, for how long. Information about the parking space usage status also includes information about when and for how long an electric vehicle or non-electric vehicle was parked without charging.

[0055] Furthermore, the output control unit 117 can control the output of alert information to notify users of information about the parking space usage status when the information about the parking space usage status has a predetermined importance or urgency, such as when unauthorized use of a parking space is identified.

[0056] The output mode when the output control unit 117 outputs various pieces of information is not particularly limited. For example, the various pieces of information may be transmitted as electronic data to a predetermined destination and output in a mode in which the information is displayed on a display or the like of an information processing device of the destination (for example, the user terminal 70). Alternatively, the various pieces of information may be output as printed matter printed on paper or the like.

[0057] The revenue calculation unit 118 calculates the revenue that the provider of the EV charger 50 can earn from the fee paid when a driver who parks an electric vehicle in a parking space uses the EV charger 50. For example, based on the operating status of the EV charger 50 output by the control of the output control unit 117, the revenue calculation unit 118 calculates the running revenue that can be continuously earned by allowing a driver who parks an electric vehicle in a parking space to use the EV charger 50.

[0058] The cost calculation unit 119 calculates the costs incurred by operating the EV charger 50. For example, the cost calculation unit 119 calculates the running costs incurred by the continuous operation of the EV charger 50 based on the operating status of the EV charger 50 output under the control of the output control unit 117.

[0059] <Processing flow of the management server 10> FIG. 6 is a flowchart showing an example of the processing flow of the management server 10. When the management server 10 receives a detection result of whether or not a vehicle is present from the sensor unit 30 installed in each parking space together with the EV charger 50 (YES in step 101), the management server 10 acquires the transmitted detection result of whether or not a vehicle is present (step 102). The acquired detection result is stored and managed in a database. On the other hand, if the detection result of whether or not a vehicle is present has not been transmitted (NO in step 101), the management server 10 repeats the determination process of step 101.

[0060] Furthermore, when information regarding charging by the EV charger 50 is transmitted from the sensor unit 30 (YES in step 103), the management server 10 acquires the transmitted information regarding charging (step 104). The acquired information regarding charging is stored and managed in a database. On the other hand, when information regarding charging has not been transmitted (NO in step 103), the management server 10 repeats the determination process in step 103.

[0061] The management server 10 detects whether charging is being performed by the EV charger 50 for each parking space based on the detection result of the presence or absence of a vehicle acquired in step 102 and the information related to charging acquired in step 104 (step 105). Specifically, for example, the management server 10 detects whether charging is being performed by the EV charger 50 for each parking space based on the detection result of the presence or absence of a vehicle and the charging record information included in the information related to charging.

[0062] The management server 10 associates and manages the two types of detection results for a predetermined period (step 106). Specifically, the management server 10 associates the detection result of the presence or absence of a vehicle in each parking space detected by the sensor unit 30 with the detection result of the presence or absence of charging detected by the management server 10 itself, stores the results in a database, and manages them.

[0063] The management server 10 calculates the usage record for each parking space for a predetermined period based on the detection result of the presence or absence of a vehicle in each parking space (step 107).The management server 10 also calculates the charging record for each parking space for a predetermined period based on the detection result of the presence or absence of charging by the EV charger 50 in each parking space (step 108).

[0064] The management server 10 outputs the operation status of the EV charger 50 for each parking space based on the usage record for each parking space calculated in step 107 and the charging record for each parking space calculated in step 108 (step 109). The management server 10 calculates the running revenue that can be obtained from allowing the EV charger 50 to be used based on the operation status of the EV charger 50 (step 110). The management server 10 also calculates the running costs required to operate the EV charger 50 based on the operation status of the EV charger 50 (step 111).

[0065] When the management server 10 receives an instruction to output the balance information (YES in step 112), it outputs balance information based on the initial cost required to install the EV charger 50 and the calculated running revenue and running costs (step 113). The balance information may also include recovery forecast information. This ends the processing of the management server 10 (END). On the other hand, when there is no instruction to output the balance information (NO in step 112), the management server 10 repeats the decision processing of step 112. The instruction to output the balance information is given, for example, by an input operation on the user terminal 70 by the user receiving the service.

[0066] <Example> FIG. 7 is a diagram showing a specific example of a parking lot 20 to which this service is applied. FIG. 8 is a conceptual diagram showing a specific example of a method in which the sensor unit 30 detects the presence or absence of a vehicle. 7, parking lot 20 is provided with parking bays 21-1 to 21-8 that can accommodate electric and non-electric vehicles. Each of parking bays 21-1 to 21-8 is equipped with a sensor unit 30-1 to 30-8 that detects whether or not a vehicle is parked. Furthermore, each of parking bays 21-1 to 21-4 is equipped with an EV charger 50-1 to 50-4 that can charge electric vehicles.

[0067] For example, suppose that an electric vehicle was parked in parking space 21-1 for two hours, from 9:00 AM to 11:00 AM on March 1, 20XX, and was charged by EV charger 50-1 during that time. In this case, the detection result of the presence or absence of a vehicle sent from sensor unit 30-1 to management server 10 (see FIG. 1) includes information indicating that a vehicle was parked in parking space 21-1 for two hours, from 9:00 AM to 11:00 AM on March 1, 20XX.

[0068] Here, assume that the vehicle presence detection results transmitted from sensor unit 30-1 are the results of vehicle presence detection transmitted every 30 seconds that have changed in state. In this case, the vehicle presence detection results for parking space 21-1 transmitted from sensor unit 30-1 include the detection of a vehicle at 9:00 AM on March 1, 20XX, and the failure to detect a vehicle at 11:00 AM on March 1, 20XX.

[0069] 8, the sensor unit 30 detects the presence or absence of a vehicle in a parking space every 30 seconds, and transmits the detection result to the management server 10 each time the status changes. If the sensor unit 30 cannot detect a vehicle, it recognizes that the parking space is "vacant" and repeats the process of detecting the presence or absence of a vehicle every 30 seconds. Then, when the sensor unit 30 detects a vehicle at a certain timing, it recognizes that the status of the parking space has changed from "vacant" to "parked" and transmits the detection result to the management server 10.

[0070] In the example of FIG. 7, sensor unit 30-1 detects the presence or absence of a vehicle in parking space 21-1 every 30 seconds, and when it detects a vehicle in parking space 21-1 at 9:00 AM on March 1, 20XX, it recognizes that the status has changed from "empty" to "parked." Then, sensor unit 30-1 transmits the detection result to management server 10. After that, sensor unit 30-1 repeatedly detects the presence or absence of a vehicle in parking space 21-1 every 30 seconds, but does not transmit the detection result to management server 10 unless the status changes. In other words, sensor unit 30-1 recognizes that parking space 21-1 is "parked" unless the status changes.

[0071] If the sensor unit 30-1 fails to detect a vehicle in the parking space 21-1 at 11:00 AM on March 1, 20XX while repeatedly detecting the presence or absence of a vehicle every 30 seconds, it recognizes that the status of the parking space 21-1 has changed from "parked" to "vacant." The sensor unit 30-1 then transmits the detection result to the management server 10. After that, the sensor unit 30-1 repeats the detection of the presence or absence of a vehicle in the parking space 21-1 every 30 seconds, but does not transmit the detection result to the management server 10 unless the status changes. In other words, the sensor unit 30-1 recognizes that the parking space 21-1 is "vacant" unless the status changes.

[0072] Furthermore, sensor unit 30-1 transmits information about charging by EV charger 50-1, obtained from EV charger 50-1, to management server 10. In this case, the information about charging by EV charger 50-1 transmitted by sensor unit 30-1 after 11:00 AM on March 1, 20XX, includes, for example, the following charging history information: That is, the transmitted charging history information includes information indicating that charging was performed by EV charger 50-1 for two hours, from 9:00 AM to 11:00 AM on March 1, 20XX.

[0073] Management server 10 associates the detection result of the presence or absence of a vehicle in parking space 21-1, which is transmitted from sensor unit 30-1, with charging history information included in the information related to charging by EV charger 50-1. The information associating the detection result of the presence or absence of a vehicle in parking space 21-1 with the charging history information of EV charger 50-1 includes various information that makes it possible to understand the usage status of parking space 21-1. Specifically, for example, the information includes information that a vehicle was parked in parking space 21-1 and charged by EV charger 50-1 for two hours, from 9:00 AM to 11:00 AM on March 1, 20XX. In this case, the information includes information that the parked vehicle is an electric vehicle.

[0074] In addition to the above cases, for example, suppose that a non-electric vehicle was parked in parking space 21-2 for three hours from 1:00 PM to 4:00 PM on March 2, 20XX. In this case, the detection result of the presence or absence of a vehicle transmitted from sensor unit 30-2 includes information indicating that a vehicle was parked in parking space 21-2 for three hours from 1:00 PM to 4:00 PM on March 2, 20XX.

[0075] Furthermore, sensor unit 30-2 transmits information about charging by EV charger 50-2, obtained from EV charger 50-2, to management server 10. In this case, the information about charging by EV charger 50-2 transmitted by sensor unit 30-2 after 4:00 PM on March 2, 20XX, includes, for example, the following charging history information: That is, the information includes information indicating that no charging was performed by EV charger 50-2 for three hours, from 1:00 PM to 4:00 PM on March 2, 20XX.

[0076] Management server 10 associates the detection result of the presence or absence of a vehicle in parking space 21-2, which is transmitted from sensor unit 30-2, with charging history information included in the information related to charging by EV charger 50-2. The information associating the detection result of the presence or absence of a vehicle in parking space 21-2 with the charging history information of EV charger 50-2 includes various information that makes it possible to understand the usage status of parking space 21-2. Specifically, for example, the information includes information that a vehicle was parked in parking space 21-2 for three hours, from 1:00 PM to 4:00 PM on March 2, 20XX, but was not charged by EV charger 50-2. In this case, the information includes information that it is not possible to identify whether the parked vehicle is an electric vehicle or a non-electric vehicle.

[0077] Figure 9 shows specific examples of income and expenditure information output by this service and various information that serves as the basis for its calculation. Note that each value shown in Figure 9 is assumed to have been rounded up or down using a predetermined calculation method. In FIG. 9, various information used in the calculation process by the management server 10 (see FIG. 1) and the results of the calculation process are shown using "items" and "values." For example, among the items, "material and labor costs" is the combined cost of materials and construction costs (such as labor and labor costs) required to install an EV charger 50 in a parking space in a parking lot. "Subsidies" are provided by the national government, local governments, etc. as a support measure to expand charging infrastructure and cover part of the installation costs of the EV charger 50. In the example of FIG. 9, the value of the material and labor costs is "2 million yen," and the value of the subsidy is "1 million yen." "Initial costs" are calculated as the initial installation costs of the EV charger 50. Specifically, they are calculated using the formula: Initial costs = Material and labor costs - Subsidy. In the example of FIG. 9, the calculation is 2 million yen (material and labor costs) - 1 million yen (subsidy) = 1 million yen (initial costs).

[0078] The "charging fee" is the fee paid by drivers who park their electric vehicles in a parking space when using the EV charger 50, and is calculated as running revenue that can be continuously earned by the provider of the EV charger 50. In the example of FIG. 9, the charging fee is 60 yen / kWh. The "electricity fee" is the electricity usage fee that is continuously borne by the provider of the EV charger 50 to operate the EV charger 50. The "system cost" is the operating cost of various systems that is borne by the provider of the EV charger 50 to operate the EV charger 50. The system cost may include the operating cost of the operation status output system 1. The electricity fee and system cost are both calculated as running costs required to operate the EV charger 50. In the example of FIG. 9, the electricity fee is 30 yen / kWh, and the system cost is 10 yen / kWh. The "running profit" is calculated as profit that can be continuously earned by the provider of the EV charger 50. Specifically, it is calculated using the formula: Running Profit = Charging Fee - (Electricity Fee + System Cost). In the example of FIG. 9, the running profit is calculated as 60 yen / kWh (charging fee) - (30 yen / kWh (electricity fee) + 10 yen / kWh (system cost)) = 20 yen / kWh.

[0079] "Facility operating days" refers to the number of operating days per year of the parking lot where the EV charger 50 is installed. In the example of FIG. 9, the value of facility operating days is "365 days / year." This indicates that the parking lot where the EV charger 50 is installed is open every day. "Business hours" refers to the operating hours per day of the parking lot where the EV charger 50 is installed. In the example of FIG. 9, the value of business hours is "10 hours / day." This indicates that the parking lot where the EV charger 50 is installed is open for 10 hours per day. "Maximum charging time" is calculated as the maximum time that the EV charger 50 installed in the parking lot can supply power to an electric vehicle in one year. Specifically, it is calculated using the formula: Maximum charging time = Facility operating days x Business hours. In the example of FIG. 9, it is calculated as 365 days / year (facility operating days) x 10 hours / day (business hours) = 3,650 hours / year (maximum charging time).

[0080] "Charger output" is the rated output of the EV charger 50. In the example of Fig. 9, the charger output value is "6 kW." This indicates that the EV charger 50 is capable of supplying 6 kWh of power per hour to an electric vehicle parked in a parking space.

[0081] In the "Operation Rate" column, "Weekdays" indicates the operation rate of the EV charger 50 on weekdays (excluding Saturdays and Sundays). "Weekends" indicates the operation rate of the EV charger 50 on Saturdays and Sundays. In the example of FIG. 9, the weekday operation rate value is "25.0%" and the Saturday and Sunday operation rate value is "60.0%." The "Average Operation Rate" is calculated as the operation rate of the EV charger 50 including weekdays and Saturdays and Sundays. Specifically, it is calculated using the formula: Average Operation Rate = (Weekdays × 5 + Saturdays and Sundays × 2) ÷ 7. In the example of FIG. 9, it is calculated as (25.0% (Weekdays) × 5 + 60.0% (Saturdays and Sundays) × 2) ÷ 7 = 35.0% (average operation rate).

[0082] In the "Profit and Loss" column, "Year 0" indicates the initial cost. "Year 1" to "Year 6" indicate the profit for each year, which is calculated using the formula: Running Profit x Maximum Charging Time x Charger Output x Average Availability. In the example of Figure 9, the profit for each year from Year 1 to Year 6 is calculated as 20 yen / kWh (Running Profit) x 3,650 h / year (Maximum Charging Time) x 6 kW (Charger Output) x 35.0% (Average Availability) = 153,000 yen (profit for each year). "Profit" is the total profit and loss from Year 0 to Year 6. In the example of Figure 9, it is calculated as -1,000,000 yen (Year 0) + (153,000 yen x 6 (Years 1 to 6)) = approximately -80,000 yen (profit).

[0083] That is, in the example of Figure 9, since the weekday operating rate is 25% and the weekend operating rate is 60%, when the charging fee is 60 yen / kWh, the profit at the end of the sixth year is -80,000 yen, and it can be seen that the initial cost (1 million yen) cannot be recovered. However, for example, if the charging fee is revised to 70 yen / kWh, the profit will be -1 million yen (year 0) + (229,000 yen x 6 (years 1 to 6)) = approximately +380,000 yen (profit), so the initial cost can be recovered at the end of the sixth year.

[0084] It is also possible to recover the initial cost by the end of the sixth year without changing the charging fee by making operational improvements. For example, measures can be taken to encourage electric vehicles to park, such as installing traffic cones (registered trademark) in parking spaces where EV chargers 50 are installed. If this can increase the utilization rate on weekends to 80%, the average utilization rate will rise to 40.0%, meaning the initial cost can be recovered by the end of the sixth year. In other words, -1,000,000 yen (year 0) + (175,000 yen x 6 (years 1 to 6)) = approximately +70,000 yen (profit), which allows the initial cost to be recovered even if the charging fee remains at 60 yen / kWh. This service simplifies these calculations, allowing users to quickly recover their initial costs by adjusting the charging fee based on utilization status or by optimizing the utilization rate.

[0085] <Other embodiments> Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment. Furthermore, the effects of the present invention are not limited to those described in the above-described embodiment. For example, the overall configuration of the operation status output system 1 in FIG. 1, the hardware configurations of the management server 10 and the sensor unit 30 shown in FIGS. 2 and 3, and the external configuration of the sensor unit 30 in FIG. 4 are merely examples for achieving the object of the present invention and are not particularly limited. Furthermore, the functional configuration of the management server 10 shown in FIG. 5 is also merely an example for achieving the object of the present invention and is not particularly limited. In other words, it is sufficient for the operation status output system 1 in FIG. 1 to have the function of being able to execute the above-described processing as a whole, and the hardware and functional configurations used to realize this function are not limited to the above-described examples.

[0086] Furthermore, the order of the steps of the processing of the management server 10 shown in the flowchart of FIG. 6 is merely an example and is not particularly limited. The processing is not necessarily performed chronologically according to the order of the steps shown, but may be performed in parallel or individually, without necessarily being chronologically processed. For example, in FIG. 6, after the sensor unit 30 transmits the detection result of the presence or absence of a vehicle, information regarding charging by the EV charger 50 is transmitted, but this order is not specific. Furthermore, after calculating the usage history, the charging history is calculated, but this order is also not specific. Furthermore, after calculating the running revenue, the running cost is calculated, but this order is also not specific. Furthermore, the specific examples shown in each of FIGS. 7 to 9 are merely examples and are not particularly limited.

[0087] Furthermore, in the above-described embodiment, a sensor unit 30 and an EV charger 50 are installed for each parking space, but this is not limiting, and the sensor unit 30 and EV charger 50 do not have to have a one-to-one relationship with the parking space. In other words, a single sensor unit 30 may be configured to detect the presence or absence of vehicles in multiple parking spaces, or a single EV charger 50 may be configured to charge vehicles parked in each of multiple parking spaces.

[0088] To summarize the above, the operating status output system 1 of the present invention only needs to have the following configuration, and can take on a variety of different embodiments. In other words, the operation status output system 1 is an operation status output system characterized by having: a usage history calculation unit 115 of the management server 10 that calculates the usage history for each parking space during a predetermined period based on the previously acquired detection results of whether or not a vehicle is present in each predetermined parking space; a charging history calculation unit 116 of the management server 10 that calculates the charging history for each parking space during a predetermined period based on the previously acquired detection results of whether or not a vehicle is charging in each parking space; and an output control unit 117 of the management server 10 that functions as an operation status output means that outputs the operation status of the EV charger 50 based on the calculated usage history and charging history for each parking space. This makes it possible to grasp the operating status of the EV charger 50 even when non-electric vehicles can be parked in the parking space where the EV charger 50 is installed.

[0089] Here, the usage history calculation unit 115 may calculate the parking time as the usage history for each parking space, the charging history calculation unit 116 may calculate the charging time as the charging history for each parking space, and the output control unit 117 may output information based on the difference between the calculated parking time and charging time for each parking space as the operating status of the EV charger 50. This makes it possible to grasp the operating status of the EV charger 50 based on the difference between the parking time and the charging time over a predetermined period of time.

[0090] The device may further include a revenue calculation unit 118 that calculates the running revenue that can be obtained by using the EV charger 50 based on the operating status of the EV charger 50, a cost calculation unit 119 that calculates the running costs required to operate the EV charger 50 based on the operating status of the EV charger 50, and an output control unit 117 that functions as a revenue output means that outputs revenue information based on the initial costs required to install the EV charger 50 and the calculated running revenue and running costs. This allows you to understand income and expenditure information.

[0091] The output control unit 117 may also be characterized by outputting income and expenditure information including recovery forecast information relating to a forecast of the period required to recover the initial cost required for installing the EV charger 50. This allows collection forecast information to be obtained.

[0092] Furthermore, when the ratio of charging time to parking time is taken as the operation rate of the EV charger 50, the output control unit 117 may be characterized by grouping days with similar usage environments and outputting recovery prediction information that takes into account the operation rate of the EV charger 50 of each group. This makes it possible to grasp collection forecast information that takes into account differences between weekdays and holidays, for example.

[0093] The output control unit 117 may be characterized by outputting collection forecast information that takes into account the unit price of running revenue. This allows collection forecast information that takes into account the unit price of running revenue to be obtained.

[0094] The operating status output method of the present invention may be configured as follows, and may take various forms. In other words, the operational status output method of the present invention is an operational status output method characterized by including the steps of: calculating the usage history for each predetermined parking space during a predetermined period based on the detection results of whether or not a vehicle is present in each predetermined parking space, which have been obtained in advance; calculating the charging history for each parking space during the period based on the detection results of whether or not a vehicle is charging in each parking space, which have been obtained in advance; and outputting the operational status of an EV charger based on the calculated usage history and charging history. This makes it possible to grasp the operating status of the EV charger 50 even when non-electric vehicles can be parked in the parking space where the EV charger 50 is installed.

[0095] The program of the present invention may be configured as follows and may take various forms. In other words, the program of the present invention is a program that enables a computer to realize the following functions: calculate the usage history for each predetermined parking space during a predetermined period based on the detection results of whether or not a vehicle is present in each predetermined parking space, which have been obtained in advance; calculate the charging history for each parking space during the period based on the detection results of whether or not a vehicle is charging in each parking space, which have been obtained in advance; and output the operating status of an EV charger based on the calculated usage history and charging history. This makes it possible to grasp the operating status of the EV charger 50 even when non-electric vehicles can be parked in the parking space where the EV charger 50 is installed.
