DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0012] 1 shows the configuration of a cost calculation system including a cost calculation device according to an embodiment of the present disclosure. This cost calculation system includes a terminal 1, a vehicle 1a, and a cost calculation device 2. Here, the cost calculation device 2 is connected to the terminal 1 and the vehicle 1a via a network. The network is a communication network that transmits and receives data between the cost calculation device 2 and the terminal 1 and the vehicle 1a, and is configured, for example, by the Internet, an intranet, a wide area network (WAN), or a local area network (LAN).

[0013] The terminal 1 is used by a user to input introduction information of an electric vehicle to be introduced, and is composed of an information processing terminal such as a computer, tablet, or smartphone. When the introduction information is input, the terminal 1 transmits the introduction information to the cost calculation device 2. Here, the terminal 1 may be a terminal used by a user who plans to introduce an electric vehicle, or a terminal used by an administrator who manages the cost calculation device 2. An electric vehicle is a vehicle that runs on electricity, and may include, for example, an electric vehicle or a hybrid vehicle. The introduction of an electric vehicle may include, for example, the purchase of an electric vehicle, or the rental of an electric vehicle (for example, leasing, rental, etc.). The introduction information is information related to the introduction of electric vehicles, and may include, for example, the planned number of electric vehicles to be introduced, the type, and the planned driving route.

[0014] Vehicle 1a is a vehicle used (e.g., owned or rented) by a user introducing an electric vehicle, and may include, for example, a vehicle driven by an engine (diesel engine, gasoline engine, etc.). Vehicle 1a transmits driving information according to driving to cost calculation device 2. For example, vehicle 1a is registered in advance in cost calculation device 2 and can transmit driving information that changes according to driving to cost calculation device 2 via a communication device. Vehicle 1a may also be a vehicle that drives a specific route R1 that includes a planned driving route of the electric vehicle to be introduced, or may be, for example, a vehicle that is planned to be replaced with an electric vehicle.

[0015] The cost calculation device 2 includes an acquisition unit 3 and a control unit 4. The acquisition unit 3 is electrically connected to the control unit 4. The cost calculation device 2 can be configured, for example, from a server or the like.

[0016] The acquisition unit 3 acquires driving information when the vehicle 1a travels along a specific route R1, and introduction information including the planned number of electric vehicles to be introduced by the user.

[0017] For example, the travel information may include the position information, average vehicle speed, travel distance, fuel consumption, etc. of the vehicle 1a. At this time, the acquisition unit 3 may directly acquire the travel information from the vehicle 1a, or may calculate the travel information based on the information transmitted from the vehicle 1a. For example, the acquisition unit 3 can calculate the average vehicle speed when the vehicle 1a traveled along the route R1 based on the position information and the change in the vehicle speed transmitted from the vehicle 1a. Furthermore, the acquisition unit 3 can calculate the travel distance when the vehicle 1a traveled along the route R1 based on the position information transmitted from the vehicle 1a. Furthermore, the acquisition unit 3 can calculate the fuel consumption when the vehicle 1a traveled along the route R1 based on the fuel information (e.g., fuel flow rate, remaining amount of fuel) transmitted from the vehicle 1a. Here, the travel information may be acquired from one vehicle 1a traveling along the route R1, or may be acquired by combining information of a plurality of vehicles 1a traveling along a part of the route R1.

[0018] At this time, the specific route R1 may be set by a user or an administrator of the cost calculation device 2, or may be automatically set by the acquisition unit 3. For example, the acquisition unit 3 may set the specific route R1 based on a planned driving route of the electric vehicle. Also, the acquisition unit 3 may set the specific route R1 based on a designation of the vehicle 1a that replaces the electric vehicle. For example, when the vehicle 1a is a delivery vehicle, the acquisition unit 3 can set the delivery route of the vehicle 1a to the specific route R1 based on the designation of the vehicle 1a.

[0019] The control unit 4 calculates the introduction cost including the cost of charging equipment for charging the electric vehicles based on the traveling information of the vehicle 1a acquired by the acquisition unit 3 and the planned number of electric vehicles to be introduced. Examples of the introduction cost include the cost of the charging equipment (e.g., purchase cost, rental cost), the cost of the electric vehicle (e.g., purchase cost, rental cost), and the amount paid by public services (e.g., subsidy, grant, benefit). The control unit 4 transmits the introduction cost to the terminal 1, for example.

[0020] Next, a detailed description will be given of the hardware configuration of the cost calculation device 2. For example, as shown in Fig. 2, the cost calculation device 2 has a storage device 5, a processor 6, a user interface (UI) device 7, and a communication device 8, which are interconnected via a bus B.

[0021] The programs or instructions for implementing the various functions and processes of the cost calculation device 2 may be downloaded from any external device via a network, etc. Also, the programs or instructions for implementing the various functions and processes of the cost calculation device 2 may be provided from a removable storage medium such as a CD-ROM (Compact Disk-Read Only Memory) or a flash memory.

[0022] The storage device 5 may be realized by one or more non-transitory storage media, such as, for example, random access memory, flash memory, or a hard disk drive, and may store installed programs or instructions as well as files or data used in the execution of the programs or instructions.

[0023] The processor 6 may be realized by one or more central processing units (CPUs), graphics processing units (GPUs), processing circuitry, etc., each of which may be composed of one or more processor cores. The processor 6 executes various functions and processes of the cost calculation device 2 according to data such as programs, instructions, programs, or parameters (e.g., parameters required for executing instructions) stored in the storage device 5.

[0024] The user interface device 7 may be composed of input devices such as a keyboard, a mouse, a camera, or a microphone, output devices such as a display, a speaker, a headset, or a printer, and input / output devices such as a smartphone, a tablet, or a touch panel.

[0025] The communication device 8 is realized by various communication circuits that execute wired and / or wireless communication processing with an external device, the Internet, a LAN (Local Area Network), a cellular network, or other communication network.

[0026] It should be noted that the above-described hardware configuration is merely an example, and the cost calculation device 2 according to the present disclosure may be realized by any other appropriate hardware configuration.

[0027] Next, the operation of this embodiment will be described with reference to the flowchart of FIG.

[0028] First, as shown in Fig. 1, in step S1, the acquisition unit 3 of the cost calculation device 2 acquires driving information when the vehicle 1a travels a specific route R1. Here, the vehicle 1a is assumed to be an engine-driven vehicle used (e.g., owned, leased, etc.) by a user. For example, the vehicle 1a is registered in advance in the cost calculation device 2, and the vehicle 1a transmits the driving information to the cost calculation device 2 via a communication unit mounted on the vehicle 1a.

[0029] For example, consider a case where vehicle 1a is a delivery vehicle that travels around predetermined delivery destinations in a predetermined period (e.g., one day). When vehicle 1a travels along a specific route R1 toward the delivery destination, it transmits travel information such as its position information, vehicle speed, or fuel information to cost calculation device 2. At this time, specific route R1 does not have to be the same route every day, and may be changed within a predetermined range depending on the delivery destination, for example.

[0030] When the acquisition unit 3 receives the travel information transmitted from the vehicle 1a, the acquisition unit 3 sequentially stores the travel information in the storage device 5. At this time, the acquisition unit 3 may calculate the route R1 traveled by the vehicle 1a during a predetermined period based on the position information of the vehicle 1a. The acquisition unit 3 may also calculate the travel distance when the vehicle 1a traveled the route R1 as the travel information based on the position information of the vehicle 1a. The acquisition unit 3 may also calculate the average vehicle speed when the vehicle 1a traveled the route R1 as the travel information based on the position information and vehicle speed of the vehicle 1a. The acquisition unit 3 may also calculate the fuel consumption when the vehicle 1a traveled the route R1 as the travel information based on the position information and fuel information of the vehicle 1a. In this way, when the acquisition unit 3 acquires the travel information of the vehicle 1a, the acquisition unit 3 stores the travel information in the storage device 5.

[0031] Next, in step S2, the acquisition unit 3 acquires introduction information including the planned number of electric vehicles to be introduced. Here, it is assumed that the user is considering introducing an electric vehicle (e.g., purchasing or renting). For example, as shown in Fig. 4, the terminal 1 displays an input screen for electric vehicle introduction information in response to an operation by the user or an administrator of the cost calculation device 2, and accepts input of the introduction information. The terminal 1 can accept input of, for example, the planned number of electric vehicles to be introduced 9, the type of electric vehicle 10, and the planned driving route R2 of the electric vehicle.

[0032] At this time, if a specific route R1 traveled by the vehicle 1a in the past is included in the planned travel route R2 of the electric vehicle, the user may input the identification information 12 of the vehicle 1a as the planned travel route R2. For example, when the user trades in the vehicle 1a currently in use for an electric vehicle, the user may input the identification information 12 of the vehicle 1a. The user may also input the identification information 13 of the route R1 as the planned travel route R2.

[0033] When the introduction information is input, the terminal 1 transmits the introduction information to the cost calculation device 2 in response to a user's operation of the send button 14. As a result, a calculation request for the introduction cost of introducing the electric vehicle is transmitted to the cost calculation device 2.

[0034] Then, the acquisition unit 3 of the cost calculation device 2 acquires introduction information including the planned number of vehicles 9 to be introduced transmitted from the terminal 1. The acquisition unit 3 also acquires a planned driving route R2 of the electric vehicle including the specific route R1 transmitted from the terminal 1. Upon acquiring the introduction information, the acquisition unit 3 outputs the introduction information to the control unit 4.

[0035] When the introduction information of the electric vehicle is input from the acquisition unit 3, the control unit 4 refers to the storage device 5 based on the introduction information and extracts travel information of the vehicle 1a traveling on the route R1 corresponding to the planned travel route R2 in step S3. For example, when the identification information 12 of the vehicle 1a or the identification information 13 of the route R1 is input as the planned travel route R2, the control unit 4 extracts the travel information of the vehicle 1a from the storage device 5 based on the identification information 12 or 13. At this time, when the planned travel route R2 is set by combining a plurality of routes R1, the control unit 4 may extract a plurality of pieces of travel information corresponding to the plurality of routes R1.

[0036] Next, in step S4, the control unit 4 calculates the introduction cost of the electric vehicles. For example, the control unit 4 can calculate the introduction cost including the cost of the electric vehicles based on the planned number of vehicles 9 to be introduced and the type 10 of the electric vehicles.

[0037] Furthermore, the control unit 4 calculates an introduction cost including the cost of charging equipment for charging the electric vehicle based on the extracted driving information of the vehicle 1a and the introduction information including the planned number of vehicles 9 to be introduced. Specifically, the control unit 4 can calculate the electricity consumption of the electric vehicle when traveling along the planned driving route R2 based on the driving information of the vehicle 1a, and calculate the cost of the charging equipment based on the electricity consumption and the planned number of vehicles 9 to be introduced.

[0038] Here, the control unit 4 can store in advance in the storage device 5 a conversion formula that indicates the change in electricity consumption of the electric vehicle with respect to the average vehicle speed and travel distance of the vehicle driven by the engine, and calculate the electricity consumption of the electric vehicle from the conversion formula based on the average vehicle speed of the vehicle 1a when traveling the route R1. The control unit 4 can also calculate the electricity consumption of the electric vehicle using the fuel consumption of the vehicle 1a.

[0039] At this time, the control unit 4 may calculate the electricity consumption of the electric vehicle by considering not only the amount of electricity consumed during driving but also the amount of electricity consumed in the mounting (e.g., freezing, refrigeration, etc.). For example, the control unit 4 can calculate the average amount of electricity consumed in the mounting based on the pre-registered business type of the user (e.g., convenience store, delivery business, etc.) or the specifications of the vehicle 1a (e.g., freezing specifications, refrigeration specifications, vehicle weight, vehicle size, etc.), and calculate the electricity consumption of the electric vehicle based on the average amount of electricity.

[0040] When the control unit 4 calculates the electricity cost of the electric vehicle, it calculates the cost of the charging equipment based on the planned number 9 of electric vehicles to be introduced and the electricity cost. Here, the acquisition unit 3 can acquire in advance the planned stopping time for the electric vehicle to be stopped after introduction. For example, the acquisition unit 3 can calculate the planned stopping time of the electric vehicle based on the traveling information of the vehicle 1a stored in the storage device 5 (e.g., position information, vehicle speed, engine driving information, etc.). Furthermore, the acquisition unit 3 may directly acquire the introduction information including the planned stopping time of the electric vehicle from the terminal 1.

[0041] The charging facility is a facility for charging an electric vehicle, and may include, for example, a charger (e.g., a normal charger or a rapid charger), a substation device (e.g., a cubicle), etc. The planned stopping time is a stopping time (free time) during which the electric vehicle can be charged by a charger, and may be, for example, the time from the end of a delivery to the start of the next day's delivery.

[0042] The control unit 4 calculates the type and number of chargers to be introduced based on the planned number 9 of electric vehicles to be introduced, the electricity cost, and the planned stopping time acquired by the acquisition unit 3. Specifically, the control unit 4 calculates the charge amount to be charged for each electric vehicle after introduction based on the planned number 9 of electric vehicles to be introduced and the electricity cost when traveling along the planned traveling route R2. Then, the control unit 4 calculates the type and number of chargers to be introduced based on the charge amount and the planned stopping time of the electric vehicles.

[0043] For example, as shown in Fig. 5, when the planned number of vehicles 9 to be introduced is seven, the control unit 4 calculates the charge amount for each of the seven electric vehicles. Then, based on the charge amounts of the seven electric vehicles, the control unit 4 calculates the type and number of chargers to be introduced that can charge the seven electric vehicles within the planned stopping time 15 with less than a predetermined amount of power, based on the charge amounts of the seven electric vehicles. Here, the planned stopping time 15 is from 10 pm to 7 am. The predetermined amount of power indicates the upper limit of the amount of power that can be transformed by a normal transformer, i.e., the upper limit of the amount of power that does not require the installation of a power receiving and transforming device.

[0044] Specifically, the control unit 4 determines whether seven electric vehicles can be charged using only normal chargers within the planned stopping time 15 with less than the specified amount of power. If the control unit 4 determines that charging is possible using only normal chargers, it calculates the number of normal chargers as the number of chargers to be introduced. On the other hand, if seven electric vehicles cannot be charged within the planned stopping time 15 even if the number of normal chargers is increased to the maximum extent possible so as to be less than the specified amount of power, the control unit 4 calculates the number of rapid chargers to be introduced. If seven electric vehicles can be charged within the planned stopping time 15 with less than the specified amount of power by introducing rapid chargers, the control unit 4 calculates the number of normal chargers and rapid chargers as the number of chargers to be introduced.

[0045] When the control unit 4 calculates the type and number of chargers to be introduced, it calculates the cost of the charging equipment based on the type and number of chargers to be introduced. In this way, the control unit 4 can calculate the cost of the charging equipment, and can accurately calculate the overall introduction cost before introducing electric vehicles.

[0046] Furthermore, if the electric vehicle cannot be charged with less than a predetermined amount of power, the control unit 4 calculates the cost of the charging equipment, including the power receiving and transforming device. In this way, the control unit 4 calculates the cost of the charging equipment, including the cost of the power receiving and transforming device, based on the type and number of chargers to be introduced, so that the overall introduction cost can be calculated more accurately before the introduction of the electric vehicle.

[0047] Here, the control unit 4 can calculate the introduction cost including the operating cost of the charging facility based on the type and number of chargers introduced. For example, the control unit 4 can calculate the electricity fee to be paid to the power company (e.g., the basic fee paid for the contracted power consumption (kW)) as the operating cost based on the type and number of chargers introduced. The control unit 4 can also calculate the electricity fee to be paid to the power company (e.g., the electricity fee paid for the amount of power used (kWh)) as the operating cost based on the amount of charge of the seven electric vehicles. In this way, the control unit 4 can more accurately calculate the overall introduction cost before the introduction of the electric vehicles by calculating the operating cost of the charging facility.

[0048] Furthermore, the control unit 4 can calculate the introduction cost based on the public service information. For example, the acquisition unit 3 acquires the public service information from a website of an administrative agency (for example, a central government agency, a local government, etc.). Examples of the public service information include subsidies, grants, and benefits for charging facilities or electric vehicles. The control unit 4 determines whether the charging facilities or electric vehicles introduced by the user are subject to the public service based on the public service information acquired by the acquisition unit 3. If the charging facilities or electric vehicles are subject to the public service, the control unit 4 calculates the introduction cost based on the corresponding public service. For example, the control unit 4 can deduct the amount subsidized by the public service from the introduction cost. This allows the control unit 4 to more accurately calculate the overall introduction cost before introducing the electric vehicle.

[0049] In this way, when the control unit 4 calculates the introduction cost, it outputs the introduction cost in step S5. For example, the control unit 4 transmits the introduction cost to the terminal 1. As a result, the terminal 1 can display the introduction cost 16 calculated by the cost calculation device 2, as shown in FIG.

[0050] According to this embodiment, the acquisition unit 3 acquires driving information when the vehicle 1a travels along a specific route R1, and the planned number 9 of electric vehicles that run on electric power. Then, the control unit 4 calculates the introduction cost 16, including the cost of charging equipment for charging the electric vehicles, based on the driving information and the planned number 9. This allows the control unit 4 to accurately calculate the introduction cost 16 before introducing the electric vehicles. Furthermore, the user can calculate the profitability of introducing the electric vehicles based on the introduction cost 16 before introducing the electric vehicles.

[0051] In addition, the above-mentioned embodiments are merely examples of the embodiment of the present invention, and the technical scope of the present invention should not be interpreted as being limited by these. That is, the present invention can be implemented in various forms without departing from the gist or main features of the present invention. For example, the disclosure of the shape and number of each part described in the above-mentioned embodiments is merely an example, and can be implemented by appropriately changing them.
