[Technical field]

[0001] The present invention relates to an output device and an output system for outputting costs relating to an electric vehicle. [Background technology]

[0002] There are known techniques for predicting the cost of running a vehicle. For example, Patent Document 1 discloses a method for predicting the cost of running a vehicle the next time it is driven based on the amount of fuel consumed when the vehicle is driven. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-278559 A Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, the replacement of engine vehicles with electric vehicles is being recommended. However, with the technology of Patent Document 1, even if the cost of the next run of the engine vehicle is known, the cost required to replace the engine vehicle with an electric vehicle is not known, making it difficult to encourage the replacement of engine vehicles with electric vehicles.

[0005] The present invention has been made in consideration of these points, and has an object to easily grasp the costs involved in replacing an internal combustion engine vehicle with an electric vehicle. [Means for solving the problem]

[0006] In a first aspect of the present invention, an output device is provided that has an acquisition unit that acquires a distance traveled by an engine vehicle, an estimation unit that estimates required power for an electric vehicle to travel a unit distance based on a reference power required for the electric vehicle to travel the distance and the distance, and an output unit that outputs the cost of enabling the supply of the required power estimated by the estimation unit based on information indicating the cost required to supply a predetermined amount of power.

[0007] The acquisition unit may acquire the reference power corresponding to the fuel efficiency when the engine vehicle travels the distance, and the estimation unit may estimate the required power as the product of the reference power acquired by the acquisition unit and the distance.

[0008] The acquisition unit may acquire the fuel efficiency of the engine vehicle while it is traveling based on a value obtained by subtracting the amount of fuel consumed while the engine vehicle is stopped to operate equipment mounted on the engine vehicle using engine power while the engine vehicle is stopped from the total amount of fuel consumed when the engine vehicle travels the distance.

[0009] The estimation unit may estimate, as the required power, a value obtained by adding up a product of the reference power and the distance and power consumption according to the power consumption during the stoppage.

[0010] The acquisition unit may acquire the power consumption consumed when the engine vehicle travels the distance, and the estimation unit may estimate the required power as a value obtained by adding the product of the distance and the reference power and the power consumption.

[0011] The output unit may output an introduction cost corresponding to the required power estimated by the estimation unit, based on information indicating a relationship between the power supplied to the electric vehicle and an introduction cost for introducing equipment for supplying the power.

[0012] The output unit may output an introduction cost corresponding to the required power as a cost required to supply the required power from a data table indicating a relationship between the power and an introduction cost of equipment that supplies the power.

[0013] The output unit may obtain the installation cost corresponding to the required power by inputting the required power into a function that outputs the installation cost of equipment that supplies the power when the power is input, and output the obtained installation cost.

[0014] In a second aspect of the present invention, there is provided an output system having an acquisition unit that acquires a distance traveled by an engine vehicle, an estimation unit that estimates a required power for an electric vehicle to travel a unit distance based on a reference power required for the electric vehicle to travel the unit distance and the distance acquired by the acquisition unit, and an output unit that outputs the cost of enabling the supply of the required power estimated by the estimation unit based on information indicating the cost required to supply a predetermined amount of power.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] In order to reduce carbon dioxide emissions, it is recommended that vehicles that run on engine power be replaced with electric vehicles that run on electricity. However, businesses that manage engine vehicles do not know the costs involved in replacing engine vehicles with electric vehicles, and are therefore unable to create budgets or plans for replacing engine vehicles with electric vehicles. As a result, there has been no encouragement to replace engine vehicles with electric vehicles.

[0018] Therefore, the output system S according to the embodiment estimates the power required for an electric vehicle to travel the distance traveled by the engine vehicle 3, and outputs the cost required to supply the required power to the electric vehicle. This allows the business operator to grasp the cost required to replace the engine vehicle 3 with an electric vehicle, and allows the business operator to prepare a budget and plan for replacing the engine vehicle 3 with an electric vehicle, making it easier to replace the engine vehicle 3 with an electric vehicle. In other words, the output system S can encourage the business operator who manages the engine vehicle 3 to replace the engine vehicle with an electric vehicle.

[0019] [Configuration of output system S] FIG. 1 is a diagram for explaining the configuration of an output system S. The output system S is a system that outputs the cost required to replace an engine vehicle 3 with an electric vehicle. The output system S includes an output device 1, a server 2, and an engine vehicle 3. The engine vehicle 3 is a vehicle equipped with an engine, and runs on the power of the engine. The engine vehicle 3 communicates with the server 2 via a wireless communication line. For example, the engine vehicle 3 can communicate with the server 2 via the Internet.

[0020] The engine vehicle 3 transmits to the server 2 the mileage traveled by the engine vehicle 3 in association with identification information for identifying the engine vehicle 3. For example, when the engine of the engine vehicle 3 is stopped, the engine vehicle 3 transmits to the server 2 the mileage traveled from when the engine is started to when it is stopped in association with the identification information. The engine vehicle 3 may also transmit to the server 2 the mileage traveled in one operation from when the engine vehicle 3 leaves the business establishment to when it returns. In this case, the engine vehicle 3 transmits to the server 2 the mileage traveled in one operation from when the position of the engine vehicle 3 leaves the range including the business establishment to when the position of the engine vehicle 3 enters the said range.

[0021] Furthermore, the engine vehicle 3 transmits to the server 2 the total amount of fuel consumed when the engine vehicle 3 travels the mileage in association with the identification information of the engine vehicle 3. The engine vehicle 3 may transmit to the server 2 the air temperature when the mileage was traveled in association with the identification information.

[0022] The engine vehicle 3 may transmit the driving history of the engine vehicle 3 to the server 2. For example, the engine vehicle 3 sequentially transmits to the server 2 the driving history in which the position, speed, acceleration, and amount of fuel injected into the engine of the engine vehicle 3 are associated with the current time and identification information of the engine vehicle 3.

[0023] The engine vehicle 3 transmits the total power consumption consumed while traveling to the server 2. The total power consumption is, for example, the power consumed by electronic devices mounted on the engine vehicle 3 while the engine vehicle 3 is traveling. The electronic devices are actuators that operate the accelerator, brake, and steering mechanisms, and a group of sensors that detect the state of the engine vehicle 3 and the surrounding conditions of the engine vehicle 3. In addition, the engine vehicle 3 may transmit to the server 2 the power consumption consumed by devices mounted on the engine vehicle 3 while the vehicle is stopped with the engine running.

[0024] The server 2 stores the mileage and total fuel consumption transmitted from the engine vehicle 3. For example, the server 2 stores the mileage, the total consumption, and the temperature when the mileage was traveled, in association with the identification information of the engine vehicle 3. When the mileage is transmitted from each of the multiple engine vehicles 3, the server 2 stores the identification information of each engine vehicle 3 in association with the mileage and total consumption of the engine vehicle 3 corresponding to the identification information.

[0025] The server 2 may store the travel history. For example, every time the server 2 receives a travel history from the engine vehicle 3, the server 2 stores the travel history in association with the identification information of the engine vehicle 3. Specifically, the server 2 stores the travel history in which the identification information of the engine vehicle 3 is associated with the position, speed, acceleration, and amount of fuel injected into the engine of the engine vehicle 3 at each time from when the engine of the engine vehicle 3 is started to when it is stopped.

[0026] The output device 1 is, for example, a mobile terminal such as a smartphone or a tablet PC, but may also be a notebook PC or a desktop PC. The output device 1 has a communication unit 11, a touch panel 12, a storage unit 13, and a control unit 14. The communication unit 11 is a wireless communication module for transmitting and receiving information via a wireless communication line. The communication unit 11 can communicate with the server 2, for example, via the Internet.

[0027] The touch panel 12 includes an input unit 121 and a display unit 122. The input unit 121 is, for example, a touch pad. The display unit 122 is, for example, a liquid crystal display. A user can operate the output device 1 by touching an icon displayed on the screen of the display unit 122.

[0028] The storage unit 13 is a storage medium including a read only memory (ROM), a random access memory (RAM), a hard disk, etc. The storage unit 13 stores a program executed by the control unit 14.

[0029] The control unit 14 is a computation resource including a processor such as a CPU (Central Processing Unit). The control unit 14 executes a program stored in the storage unit 13 to realize functions as an acquisition unit 141, an estimation unit 142, and an output unit 143.

[0030] The acquisition unit 141 acquires the mileage of the engine vehicle 3 from the server 2 via the communication unit 11. For example, the acquisition unit 141 acquires from the server 2 the mileage of the engine vehicle 3 corresponding to the identification information input to the input unit 121. Specifically, the acquisition unit 141 acquires from the server 2 the mileage traveled by the engine vehicle 3 in one operation. More specifically, the acquisition unit 141 acquires from the server 2 the mileage traveled by the engine vehicle 3 in one operation, with the period from when the engine vehicle 3 departs from the business premises to when it returns thereto being regarded as one operation.

[0031] The acquisition unit 141 may acquire the driving history from the server 2 and acquire the driving distance based on the driving history. For example, the acquisition unit 141 calculates, for each time, the distance between a position at one time among multiple times included in the driving history and a position at the time next to the one time, and acquires the driving distance by adding up the multiple calculated distances.

[0032] The acquisition unit 141 acquires the total fuel consumption amount when the engine vehicle 3 travels a travel distance. For example, the acquisition unit 141 acquires the total consumption amount stored in the server 2. The acquisition unit 141 may also acquire the sum of the injection amounts at each time in the travel history acquired from the server 2 as the total consumption amount.

[0033] The acquisition unit 141 acquires the fuel efficiency of the engine vehicle 3 when the engine vehicle 3 travels a mileage. Specifically, the acquisition unit 141 acquires the ratio of the mileage to the total consumption as the fuel efficiency when the mileage is traveled. The fuel efficiency is the ratio of the distance traveled by consuming a unit amount of fuel to a unit amount of fuel. As a specific example, the fuel efficiency is the mileage per liter, but is not limited to this. The acquisition unit 141 may acquire the fuel efficiency stored in the storage unit 13 in advance. For example, the acquisition unit 141 can specify the total amount of fuel consumed when the engine vehicle 3 travels a mileage based on the fuel efficiency stored in the storage unit 13 and the mileage of the engine vehicle 3 acquired from the server 2.

[0034] The acquisition unit 141 may acquire the fuel efficiency based on the total consumption and the stoppage consumption of fuel consumed when the engine vehicle 3 is stopped. The stoppage consumption is the amount of fuel consumed to operate the devices mounted on the engine vehicle 3 with the engine power while the engine is started and the engine is stopped. The devices mounted on the engine vehicle 3 are, for example, compressors and generators for refrigerators and freezers, but are not limited to these, and may be any devices that operate with the engine power. The acquisition unit 141 acquires the fuel efficiency while the engine vehicle 3 is traveling based on a value obtained by subtracting the stoppage consumption from the total consumption. Specifically, the acquisition unit 141 acquires the ratio of the traveling distance to the value obtained by subtracting the stoppage consumption from the total consumption as the fuel efficiency while traveling.

[0035] The acquisition unit 141 acquires a reference power corresponding to the fuel efficiency when the engine vehicle 3 travels a travel distance. The reference power is the power required for the electric vehicle to travel a unit distance, and indicates the reciprocal of the so-called power efficiency [km / kWh]. The acquisition unit 141 may acquire the power efficiency. The reference power is, for example, the power required for the electric vehicle to travel 1 kilometer, but is not limited thereto. For example, the acquisition unit 141 acquires the reference power corresponding to the acquired fuel efficiency from a conversion table for converting the fuel efficiency into the reference power, which associates the fuel efficiency with the reference power corresponding to the fuel efficiency. FIG. 2 is a diagram showing an example of the conversion table. The acquisition unit 141 acquires the reference power corresponding to the acquired fuel efficiency by referring to the conversion table.

[0036] The acquisition unit 141 acquires a reference power according to whether or not a refrigerator is installed in the engine vehicle 3. For example, even if the fuel efficiency is the same, when the engine vehicle 3 is equipped with a refrigerator, the acquisition unit 141 acquires a reference power that is different from the reference power when the engine vehicle 3 is not equipped with a refrigerator.

[0037] The acquisition unit 141 acquires the reference power according to the temperature when the engine vehicle 3 travels a distance, in addition to the fuel efficiency and whether or not a refrigerator is installed. For example, when the fuel efficiency of the engine vehicle 3 equipped with a refrigerator when the engine vehicle 3 travels a distance at a temperature of 30 degrees is [6.50], the acquisition unit 141 acquires the reference power [0.75] corresponding to the fuel efficiency [6.50], the installation of a refrigerator [presence], and the temperature [30 degrees] (see FIG. 2). Also, when the fuel efficiency of the engine vehicle 3 not equipped with a refrigerator when the engine vehicle 3 travels a distance at a temperature of 8 degrees is [6.50], the acquisition unit 141 acquires the reference power [0.50] corresponding to the fuel efficiency [6.50], the installation of a refrigerator [absence], and the temperature [8 degrees] (see FIG. 2).

[0038] The acquisition unit 141 may further acquire the total power consumption consumed when the engine vehicle 3 travels a mileage. Specifically, the acquisition unit 141 acquires the total power consumption and the power consumption during the stoppage stored in the server 2. The acquisition unit 141 may also acquire the power generated by the engine of the engine vehicle 3 using the fuel consumed during the stoppage as the power consumption during the stoppage.

[0039] The estimation unit 142 estimates the required power required when the electric vehicle travels the distance traveled by the engine vehicle 3 in one operation. For example, the estimation unit 142 estimates the power (required power) required for the electric vehicle to travel the travel distance based on the reference power and the travel distance. Specifically, the estimation unit 142 estimates the required power based on the product of the reference power and the travel distance acquired by the acquisition unit 141. More specifically, the estimation unit 142 estimates the required power as a value obtained by adding up the product of the reference power and the travel distance and the total power consumption while traveling. The estimation unit 142 may also estimate the required power as a value obtained by adding up the product of the reference power and the travel distance and the power consumption while the vehicle is stopped.

[0040] The output unit 143 outputs and displays the cost of enabling the supply of the required power estimated by the estimation unit 142 on the display unit 122. For example, the output unit 143 displays the introduction cost for introducing equipment that enables the supply of the required power to a waiting electric vehicle on the display unit 122. Specifically, the output unit 143 displays on the display unit 122 the cost for introducing equipment that enables the charging of the battery of the electric vehicle with the required power during the waiting time from when the electric vehicle returns to the business premises to when it departs from the business premises.

[0041] The equipment capable of supplying the required power is, for example, a charger and a power receiving equipment, but is not limited to these and includes equipment required to supply power to an electric vehicle. The power receiving equipment is composed of one or more devices that convert the power received from the power company that supplies the power to a voltage suitable for the charger and distribute the power to the charger. The installation cost may include the construction cost for installing the equipment and the fee for the contract with the power company.

[0042] The output unit 143 displays the cost of supplying the estimated required power on the display unit 122 based on the information indicating the cost required to supply the predetermined power. The information indicating the cost required to supply the predetermined power is, for example, information indicating the relationship between the predetermined power and the cost required to supply the predetermined power. Specifically, the information indicating the relationship between the predetermined power and the cost required to supply the predetermined power is information indicating the relationship between the power supplied to the electric vehicle and the introduction cost for introducing the equipment that supplies the power. The information indicating the relationship between the power and the introduction cost is, for example, a data table that associates the power with the introduction cost of the equipment that supplies the power. The data table is stored in the storage unit 13. FIG. 3 is an example of a data table that associates the power with the introduction cost. The output unit 143 identifies the introduction cost associated with the estimated required power from the data table shown in FIG. 3.

[0043] When the business operator manages a plurality of engine vehicles 3, the output unit 143 causes the display unit 122 to display the installation cost of equipment for supplying the total required power obtained by adding up the required power corresponding to each engine vehicle 3. As a specific example, if the required power corresponding to each of five of six engine vehicles 3 managed by the business operator is 10 kWh and the required power corresponding to the traveling distance of the remaining engine vehicle 3 is 50 kWh, the output unit 143 causes the display unit 122 to display the installation cost corresponding to 100 kWh.

[0044] Incidentally, the introduction cost of the facility for supplying electric power varies depending on the type of charger for charging the required power to the electric vehicle and whether or not a power receiving facility is required. The types of chargers are, for example, normal chargers and quick chargers. A normal charger uses, for example, a single-phase AC 100V outlet or 200V outlet, and takes longer to charge the desired power to the electric vehicle than a quick charger, but costs less than a quick charger. A quick charger uses, for example, a three-phase 200V outlet, and takes shorter to charge than a normal charger, but costs more than a normal charger. In addition, the cost when a power receiving facility is required is higher than the cost when a power receiving facility is not required.

[0045] Therefore, in order to output a more accurate introduction cost, the acquisition unit 141 acquires the type of charger and whether or not power receiving equipment is required. For example, the acquisition unit 141 displays an input screen for receiving input of the type of charger and whether or not power receiving equipment is required on the display unit 122, and acquires the input type of charger and whether or not power receiving equipment is required. Fig. 4 is an example of the input screen.

[0046] The acquisition unit 141 displays an input screen including an input field 45 for the type of charger and an input field 46 for whether or not power receiving equipment is required on the display unit 122. A user of the output device 1 can input the type of charger into the input field 45 and whether or not power receiving equipment is required into the input field 46. The acquisition unit 141 acquires the type of charger that the user wishes to introduce and whether or not power receiving equipment is required, which have been input into the input unit 121.

[0047] When the required power is less than the power threshold at which a power receiving facility is required, the acquisition unit 141 may display an input field 46 indicating that a power receiving facility is not required. The power threshold at which a power receiving facility is required is, for example, 50 kWh, but may be determined according to the location of the business operator introducing the electric vehicle.

[0048] The acquisition unit 141 causes the display unit 122 to display an input screen including the acquired information, together with an input field 45 for the type of charger and an input field 46 for whether or not power receiving equipment is required. Specifically, the acquisition unit 141 causes the travel distance to be displayed in a travel distance display field 41, the fuel efficiency to be displayed in a fuel efficiency display field 42, and the reference power to be displayed in a reference power display field 43. The acquisition unit 141 also causes the required power estimated by the estimation unit 142 to be displayed in a required power display field 44. This allows the user to grasp the travel distance and fuel efficiency of the engine vehicle 3, and the required power.

[0049] The acquisition unit 141 displays an icon 47 that accepts an instruction to output the introduction cost. The user can input an instruction to output the introduction cost by touching the icon 47. When an instruction to output the introduction cost is input, the output unit 143 identifies the introduction cost according to the required power, the type of charger, and whether or not a power receiving facility is required, from the data table shown in FIG. 3.

[0050] When the required power is 10 kWh, the type of charger is [normal], and the power receiving equipment is [unnecessary], the output unit 143 specifies [¥1,200,000] as the installation cost (see FIG. 3). Then, the output unit 143 outputs the specified installation cost to the display unit 122. In other words, the output unit 143 causes the display unit 122 to display the display image by outputting a display image including the installation cost to the display unit 122.

[0051] 5 is an example of a display image including the introduction cost. The output unit 143 causes the display unit 122 to display a display image in which the identified introduction cost is displayed in the display field 48. This allows the user to easily understand the introduction cost when replacing the engine vehicle 3 with an electric vehicle. Then, the user who has been able to understand the cost necessary for the replacement can easily secure the budget necessary for the replacement and make a plan, which encourages the replacement of the engine vehicle 3 with an electric vehicle.

[0052] The information indicating the relationship between power and the installation cost may be a function. In this case, the output unit 143 obtains the installation cost corresponding to the required power by inputting the required power into a function that outputs the installation cost of equipment that supplies power when power is input, and outputs the obtained installation cost. The output unit 143 may also output the installation cost using a function that outputs the installation cost when the type of charger and the presence or absence of power receiving equipment are input in addition to power.

[0053] Incidentally, when the multiple engine vehicles 3 managed by the business operator are replaced with multiple electric vehicles, it is possible to simultaneously charge multiple electric vehicles that are on standby. In this case, it is necessary to introduce multiple chargers to simultaneously charge multiple electric vehicles. Therefore, the acquisition unit 141 acquires the number of chargers to be introduced. For example, the acquisition unit 141 displays an input screen including an input field for the number of chargers on the display unit 122, and acquires the number input in the input field for the number of chargers as the number of chargers to be introduced. In addition, the acquisition unit 141 may accept an input of the number of engine vehicles 3 managed by the business operator, and acquire the number of engine vehicles 3 as the number of chargers to be introduced. The output unit 143 outputs the introduction cost including a value obtained by multiplying the cost of the charger corresponding to the type of charger by the number of chargers to be introduced. This allows the output unit 143 to output a more accurate introduction cost.

[0054] [Processing to output introduction costs executed by output device 1] FIG. 6 is a flowchart showing an example of a process for outputting an introduction cost. The flowchart in FIG. 6 is executed when an instruction to execute a process for outputting an introduction cost is input to the output device 1. The acquisition unit 141 acquires the mileage of the engine vehicle 3 (step S1). For example, the acquisition unit 141 acquires the mileage associated with the identification information of the engine vehicle 3 from the server 2 that stores the mileage of the engine vehicle 3. The acquisition unit 141 acquires the fuel efficiency when the engine vehicle 3 travels the mileage (step S2). Specifically, the acquisition unit 141 acquires the fuel efficiency stored in the server 2 in association with the mileage of the engine vehicle 3.

[0055] The acquiring unit 141 acquires a reference power required for the electric vehicle to travel a unit distance (step S3). For example, the acquiring unit 141 acquires a reference power corresponding to the acquired fuel efficiency from the conversion table shown in FIG.

[0056] The estimation unit 142 estimates the required power required for the electric vehicle to travel the travel distance based on the reference power and the travel distance (step S4). For example, the estimation unit 142 estimates the required power as the product of the reference power and the travel distance.

[0057] The output unit 143 causes the display unit 122 to display an input screen (see FIG. 3) including an input field 45 for the type of charger and an input field 46 for whether or not power receiving equipment is required (step S5). The output unit 143 determines whether or not input for the type of charger and whether or not power receiving equipment is required has been received (step S6). If the output unit 143 has not received input (No in step S6), the output unit 143 waits until input is received.

[0058] When the output unit 143 receives the input (Yes in step S6), it identifies the introduction cost (step S7). For example, the output unit 143 identifies the introduction cost corresponding to the required power from a data table showing the relationship between the power and the introduction cost of the equipment that supplies the power.

[0059] The output unit 143 outputs the identified introduction cost (step S8). For example, the output unit 143 causes the display unit 122 to display a display image including the introduction cost.

[0060] (Variation 1) The acquisition unit 141 may receive input of the mileage and fuel efficiency. The acquisition unit 141 acquires the mileage and fuel efficiency input in the mileage display field 41 and the fuel efficiency display field 42, respectively. This allows the user to input the mileage and fuel efficiency, and check the cost of replacing the engine vehicle 3 with an electric vehicle, even if the mileage and fuel efficiency of the engine vehicle 3 are not stored in the server 2.

[0061] (Variation 2) The server 2 stores the mileage and fuel efficiency of the engine vehicle 3 each time the engine vehicle 3 travels. The acquisition unit 141 acquires multiple mileages and fuel efficiency associated with the identification information of the engine vehicle 3. When the acquisition unit 141 acquires multiple mileages and fuel efficiency, it acquires multiple statistics of the mileage and fuel efficiency. For example, the acquisition unit 141 acquires at least one of the average, median, and mode of the multiple mileages and fuel efficiency. Then, the estimation unit 142 estimates the product of the reference power corresponding to the multiple fuel efficiency statistics and the multiple mileage statistics as the required power. This allows the output device 1 to output the introduction cost based on the required power with reduced influence of variation when the engine vehicle 3 travels.

[0062] (Variation 3) In the above embodiment, the types of chargers are two types, a normal charger and a quick charger, but the types of chargers are not limited to these, and the acquisition unit 141 may acquire one type of charger out of three or more types. In addition, the acquisition unit 141 acquires whether or not a power receiving facility is required, but the acquisition unit 141 may acquire an equipment included in the power receiving facility. When the acquisition unit 141 acquires that a power receiving facility is required, it accepts a selection of the equipment included in the power receiving facility. Then, the output unit 143 outputs an introduction cost including a cost corresponding to one type of charger out of three or more types and a cost corresponding to the selected equipment. In this way, the output device 1 can output an introduction cost according to the type of charger and equipment desired by the user.

[0063] (Variation 4) In the above embodiment, the output device 1 is a mobile terminal, but is not limited thereto and may be an information processing device such as a server. When the output device 1 is an information processing device, when the output device 1 receives an output request for the introduction cost from another terminal different from the output device 1, the output device 1 outputs the introduction cost to the other terminal. Specifically, the other terminal transmits an output request including the identification information of the engine vehicle 3 to the output device 1. The output device 1 acquires the mileage and fuel efficiency corresponding to the identification information included in the output request from the server 2, and outputs the introduction cost based on the acquired mileage and fuel efficiency to the other terminal.

[0064] (Variation 5) The output device 1 according to the embodiment outputs the introduction cost by displaying a display image on the display unit 122. This is not limiting, and the output device 1 may output the introduction cost by voice. For example, the output device 1 outputs a message saying, "The cost of replacing the engine vehicle 3 currently in operation with an electric vehicle is 1,200,000 yen."

[0065] (Variation 6) In the above embodiment, the acquisition unit 141, the estimation unit 142, and the output unit 143 are all included in the output device 1, but this is not limiting and they may be included in a plurality of different devices. For example, the output system S includes a first device having some of the acquisition unit 141, the estimation unit 142, and the output unit 143, and a second device having the remaining parts. As a specific example, the first device includes the acquisition unit 141 and the estimation unit 142, estimates the required power based on the mileage acquired by the acquisition unit 141, and notifies the second device. The second device displays the installation cost of the equipment on the display unit of the second device based on the notified required power.

[0066] [Effects of output device 1] As described above, the output device 1 according to the embodiment estimates the required power for the electric vehicle to travel a certain distance based on the distance traveled by the engine vehicle 3 and the reference power required for the electric vehicle to travel a unit distance. Then, the output device 1 outputs the cost of enabling the supply of the required power based on information indicating the cost required to supply a certain amount of power. In other words, when replacing an engine vehicle with an electric vehicle, the output device 1 outputs the cost of enabling the supply of the required power to be supplied to the electric vehicle.

[0067] The user can see the outputted cost and understand the cost involved in replacing an engine vehicle with an electric vehicle. Then, the user who has understood the cost involved in the replacement can easily make a budget and plan for replacing the engine vehicle 3 with an electric vehicle.
