FIG. 3 is a block diagram of the external device 200. It is a flowchart which calculates a tax amount. FIG. 14 illustrates an example of a computer 1200 in which aspects of the present invention may be wholly or partially embodied.

Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all combinations of the features described in the embodiments are necessarily indispensable to the solution of the invention. In the drawings, the same or similar parts are denoted by the same reference numerals, and duplicate description may be omitted.

FIG. 1 is a schematic diagram of a vehicle charging / discharging system 10. The vehicle charge / discharge system 10 includes a tax amount calculation system 15, a vehicle 20, a communication terminal 40, and a charge / discharge facility 60. The communication terminal 40 is owned by the user 30. The charge / discharge facility 60 is electrically connected to, for example, a system in which power generation, substation, power transmission, and power distribution are integrated, has a connection unit such as a connector or an outlet, and is supplied from the system via the connection unit. Power can be provided to the outside, and power supplied from the outside can be provided to the grid. The charging / discharging equipment 60 may have a storage device capable of storing electric power.

In the vehicle charge / discharge system 10, electric power is exchanged between the vehicle 20 and the charge / discharge facility 60. Further, in the vehicle charge / discharge system 10, data is transmitted and received between the taxable amount calculation system 15 and the communication terminal 40 via the communication network 50.

The tax amount calculation system 15 is a system for calculating and charging a tax amount based on the amount of power consumed by the vehicle 20 to the user 30 who uses the vehicle 20 driven by the vehicle-mounted battery. The amount of power consumption does not include at least the amount of power exchanged from the vehicle-mounted battery to the outside such as the grid or the home. Therefore, the tax amount based on the power consumption is a reasonable and appropriate value for the user 30. The taxation amount calculation system 15 is an example of a travel cost calculation system that calculates a cost for traveling of the vehicle 20 based on the amount of power consumed by the vehicle 20.

The taxation amount calculation system 15 includes an in-vehicle device 100 provided in the vehicle 20 and an out-of-vehicle device 200 arranged outside the vehicle 20 and communicating with the in-vehicle device 100 via the communication network 50. Note that the vehicle charge / discharge system 10 and the tax calculation system 15 may each include a plurality of vehicles 20 and an in-vehicle device 100 used by a plurality of users 30, but the description will be given unless otherwise noted in each embodiment. For the purpose of clarity, a configuration is provided with each one.

道路 The current road administration is operated and financed by using financial resources including taxes on gasoline, etc., for example, gasoline tax. This tax is imposed on gasoline and the like consumed by gasoline automobiles and the like using the road so as to be borne by those who enjoy the benefits of using the road. The amount of fuel consumed by a gasoline-powered vehicle or the like is generally proportional to the travel distance of the vehicle, that is, proportional to the amount of road use. Therefore, taxation in proportion to the amount of fuel is taxable in proportion to the amount of road use, and is highly relevant. On the other hand, users of electric vehicles have not yet paid taxes imposed on gasoline and the like, despite enjoying the benefits of using roads.

であれば If an electric vehicle always charges from a charging station, it is easy to charge a tax on the charging. However, charging can be performed by a privately owned charging facility, and cannot be distinguished from power consumed at home. For this reason, it is difficult to tax based on information on the power equipment on the supply side. In order to solve this problem, it is conceivable to set a uniform tax amount for the user of the electric vehicle for the purpose of road use and the like.

負担 However, there is a possibility that the load may be unevenly distributed between electric vehicles that are frequently used and electric vehicles that are not frequently used. Therefore, it is desirable to bear the tax amount according to the use of the road. Then, taxation according to the mileage of the electric vehicle is suitable. It is necessary to manage the running distance based on the running history, and it is difficult to collect data because the running history is important information among the personal information. Therefore, there is a correlation between the mileage and the power consumption, and it is considered that there is also a correlation between the power consumption and the charging power that the electric vehicle charges from the outside. Taxing is conceivable.

However, there is another problem in setting a tax amount according to the amount of electric power charged for electric vehicles. For example, when power is consumed for purposes other than the power consumed by the electric vehicle in V2G, V2H, or the like, the amount of charging power is not the power consumption of the electric vehicle. Further, for example, when one electric vehicle is shared by a plurality of people in services such as car sharing and rental car, it is not possible to tax a person who uses the electric vehicle without charging the electric vehicle. Even for those who used the vehicle after charging but did not use up the charge, it was not possible to calculate the tax amount for the travel.

On the other hand, according to the tax amount calculation system 15 of the present embodiment, the in-vehicle device 100 reads out the user ID of the user 30 who runs the vehicle 20 from the communication terminal 40 and reads the first discharge amount from the in-vehicle battery of the vehicle 20. And the second amount of discharge to the outside of the vehicle 20 is measured, and the amount of power consumed by the vehicle 20 is calculated based on the first amount of discharge and the second amount of discharge.

は In the tax amount calculation system 15 of the present embodiment, the in-vehicle device 100 further transmits a signal related to the calculated power consumption to the out-of-vehicle device 200. As a result, the external device 200 transmits, for example, the vehicle ID for identifying the individual of the vehicle 20 included in the signal from the vehicle-mounted device 100 via the communication network 50 and the user ID of the user 30 who has run the vehicle 20. The user ID for identifying the individual and the power consumption calculated by the vehicle-mounted device 100 are acquired. Further, the external device 200 calculates the cost for traveling of the vehicle 20 based on the power consumption calculated by the on-vehicle device 100. The cost for traveling of the vehicle 20 includes a tax amount for traveling of the vehicle 20. Further, the external device 200 transmits billing information for requesting the tax amount to the address of the communication terminal 40 and the in-vehicle device 100 stored in advance in association with at least one of the user ID and the vehicle ID.

FIG. 2 is a block diagram of the vehicle 20 and the vehicle-mounted device 100. The vehicle 20 includes a battery 21, a charge / discharge control unit 22, a motor 23, a storage unit 24, an electric device 25, and an external connection unit 27.

The external connection unit 27 is configured to electrically connect the vehicle 20 and a charge / discharge facility 60 outside the vehicle 20 so that the vehicle 20 can charge / discharge power between the vehicle 20 and the charge / discharge facility 60. External connection portion 27 includes an inlet into which a cable connecting between vehicle 20 and charge / discharge facility 60 is inserted. The inlet includes a connector for the charging / discharging facility 60 for normal charging that outputs a single-phase AC 100 V or 200 V supplied from the system, and a quick charge that converts the three-phase AC 200 V supplied from the system to, for example, DC 500 V and outputs the same. Connectable to at least one of the connectors for the charge / discharge facility 60 intended for use.

外 External connection unit 27 also includes an AC / DC converter for converting an AC current to a DC current, and a DC / AC inverter for converting a DC current to an AC current. Instead of this, the out-of-vehicle connection unit 27 may include a bidirectional converter capable of bidirectionally converting alternating current and direct current. The external connection unit 27 may further include a DC / DC converter that converts a DC current into a DC current having a predetermined voltage value.

外 External connection portion 27 also includes a sensor capable of detecting that vehicle 20 is electrically connected to charging / discharging facility 60. When detecting that the vehicle 20 has been electrically connected to the charge / discharge facility 60, the external connection unit 27 outputs a signal indicating this to the charge / discharge control unit 22. The external connection unit 27 outputs the electric power supplied from the charge / discharge facility 60 to the battery 21 under the control of the charge / discharge control unit 22.

The storage unit 24 stores a plurality of predetermined charge patterns in association with charge / discharge characteristics based on the SOH (State Of Health) of the battery 21. The storage unit 24 also stores the current SOH of the battery 21. The current SOH of the battery 21 stored in the storage unit 24 is updated at a predetermined timing. For example, the charge / discharge control unit 22 of the vehicle 20 calculates the current SOH of the battery 21 with reference to each measurement data stored in the storage unit 117 of the in-vehicle device 100, and stores the current SOH of the battery 21 in the storage unit 24 of the vehicle 20. The SOH of the battery 21 may be updated.

When the power switch of the vehicle 20 is turned on, the charge / discharge control unit 22 supplies electric power from the battery 21 to the electric device 25 based on setting information indicating a set value of electric power required for activation and operation of the electric device 25. Let it be supplied. The charge / discharge control unit 22 also controls supply of electric power from the battery 21 to the motor 23 based on inputs from an accelerator pedal and a brake pedal provided on the vehicle 20.

The charge / discharge control unit 22 also receives a signal indicating that the vehicle 20 is electrically connected to the charge / discharge facility 60 from the external connection unit 27, and receives information regarding charge / discharge from the outside. Charging and discharging from the battery 21.

More specifically, the charging / discharging control unit 22 transmits information such as the fact that the vehicle 20 is connected to the charging / discharging facility 60 and charging, a target SOC (State \ Of \ Charge) after charging the battery 21, a scheduled charging completion time, and the like. For example, the data is input from the charge / discharge facility 60 via the communication wiring arranged in the external connection unit 27. In this case, the charge / discharge control unit 22 performs the charge / discharge according to the input information and the charge pattern stored in the storage unit 24 and associated with the charge / discharge characteristics based on the current SOH of the battery 21. The external connection unit 27 is controlled to start charging the battery 21 from the facility 60.

Similarly, the charge / discharge control unit 22 transmits information indicating that the vehicle 20 is connected to the charge / discharge facility 60 to be discharged, the target SOC after the battery 21 has been discharged, the scheduled discharge completion time, and the like from the charge / discharge facility 60, for example. Will be entered. In this case, the charge / discharge control unit 22 controls the battery 21 to start discharging from the battery 21 to the charge / discharge facility 60 according to the input information or the like.

The charge / discharge control unit 22 further controls the power transmitted and received between the battery 21, the motor 23, the electric device 25, and the external connection unit 27, which is indicated by the plurality of measurement data stored in the storage unit 117 of the in-vehicle device 100. The charge / discharge amount between these components may be adjusted by referring to the value.

The motor 23 is driven by electric power supplied from the battery 21 controlled by the charge / discharge control unit 22, rotates the tires of the vehicle 20, and causes the vehicle 20 to run. The motor 23 also converts the rotational force of the tire when the vehicle 20 decelerates into electric power, and outputs the electric power to the battery 21 as regenerative electric power.

The electric device 25 is an example of a vehicle-mounted electric device other than the motor 23 for driving the vehicle 20, and includes, for example, an air conditioner for a vehicle, a car navigation device, and a cooler for the motor 23.

The measuring unit 101 of the in-vehicle device 100 measures a value of electric power transmitted and received between the battery 21, the motor 23, the electric device 25, and the external connection unit 27 in the vehicle 20, and stores each measured value in the storage unit of the in-vehicle device 100. 117. The measurement unit 101 includes a first measurement unit 103 and a second measurement unit 105.

The first measuring unit 103 includes an ammeter and a voltmeter, and measures the first discharge amount from the battery 21 and the first charge to the battery 21 by measuring the current value and the voltage value of the DC current flowing into and out of the battery 21. Measure the quantity. The first measuring unit 103 does not need to measure the amount of charge to the battery 21.

Similarly, the second measuring unit 105 includes an ammeter and a voltmeter, and measures the current value and the voltage value of the DC current discharged to the outside of the vehicle 20 through the outside connecting unit 27, thereby obtaining the vehicle 20 Is measured for the second discharge amount to the outside. The second measuring unit 105 may further measure the amount of charge from outside the vehicle 20. Note that, instead of the above configuration, the second measuring unit 105 may measure the current value and the voltage value of the alternating current that is converted from the direct current by the external connection unit 27 and discharged to the outside of the vehicle 20. .

(4) The timing unit 111 measures the traveling time of the vehicle 20. The traveling time is, for example, the time when the power switch of the vehicle 20 is turned on, the time when the power switch of the vehicle 20 is turned off, and the time from when the power switch of the vehicle 20 is turned on to when the power switch is next turned off. Including time. The clock unit 111 outputs the measured traveling time to the calculation unit 123.

The occupant imaging unit 113 is an example of an obtaining unit that obtains information on the number of occupants in the vehicle 20, and captures an image of the inside of the vehicle 20, obtains information on the number of occupants in the vehicle 20 as image data, and calculates a 123. The occupant imaging unit 113 is disposed, for example, above the windshield or the rear glass of the vehicle 20 so that the calculation unit 123 can grasp the number of occupants of the vehicle 20 based on the image data.

The storage unit 117 stores the vehicle ID, the user ID of the user 30, the measurement data of the measurement unit 101, the current SOC of the battery 21, the power consumption calculated by the calculation unit 123, and the like.

The communication unit 119 communicates with an external device 200 provided outside the vehicle 20. Communication unit 119 transmits a signal related to the amount of power consumed by vehicle 20 to external device 200. When receiving the billing information from the external device 200, the communication unit 119 outputs the billing information to the vehicle 20. In addition, in addition to the user ID, the vehicle ID, and the power consumption described above, the signal related to the power consumption described above includes the travel time measured by the clock unit 111 and the image acquired by the occupant imaging unit 113. Data and the like may be included.

The reading unit 121 uses a short-range wireless communication unit such as BLE (Bluetooth (registered trademark) Low Energy) to pair the in-vehicle device 100 and the communication terminal 40 in advance, and reads the user who has boarded the vehicle 20. The user ID is read from the communication terminal 40 by establishing wireless communication with the communication terminal 40 possessed by 30. The reading unit 121 outputs the read user ID to the calculating unit 123.

The vehicle-mounted device 100 can identify the driver of the vehicle 20 and the person to be charged the tax amount by acquiring the user ID to identify the user 30 driving the vehicle 20. In addition, since it is assumed that there is a passenger having a communication device in the vehicle 20, for example, by transmitting a confirmation message to the communication terminal 40 before the traveling of the vehicle 20 is started, the communication terminal 40 You may confirm that the possessed user 30 drives the vehicle 20.

Calculating section 123 causes measuring section 101 to start measuring each electric energy in response to, for example, reading the user ID from communication terminal 40 via reading section 121. The calculating unit 123 calculates the power consumption based on each measurement value from the measuring unit 101 stored in the storage unit 117. More specifically, the calculating unit 123, when a predetermined time has passed, accumulates the first discharge in the storage unit 117 by the measuring unit 101 within a predetermined period. The amount of power consumed by the vehicle 20 is calculated based on the amount and the second discharge amount. In the present embodiment, the calculation unit 123 calculates the power consumption amount by subtracting the second discharge amount from the first discharge amount.

The calculation unit 123 subtracts the amount of discharge from the vehicle 20 to the outside of the vehicle 20 from the amount of discharge from the battery 21 in the calculation for calculating the amount of power consumption of the vehicle 20, so that the system The amount of electric power that is provided to the home or the like can be excluded from the amount of electric power consumed by the vehicle 20.

Calculating section 123 further transmits the calculated amount of power consumption together with the vehicle ID and user ID stored in storage section 117 to external device 200 via communication section 119.

Note that the in-vehicle device 100 may have an internal power supply. In this case, the internal power supply may be activated by detecting that the power switch of the vehicle 20 has been turned on. Alternatively or additionally, in-vehicle device 100 may be powered by battery 21 of vehicle 20 without an internal power supply. In this case, when the power switch of the vehicle 20 is turned on under the control of the charge / discharge control unit 22 of the vehicle 20, similarly to the electric device 25 of the vehicle 20, the in-vehicle device 100 21 may be supplied with power. In this case, the in-vehicle device 100 also measures a current value supplied from the battery 21 to the in-vehicle device 100, and calculates the amount of power consumed by the vehicle 20 from the first discharge amount. The current value may be subtracted.

FIG. 3 is a block diagram of the external device 200. The external device 200 is, for example, a server provided in a taxing center that charges a user 30 of the vehicle 20 a tax amount for traveling of the vehicle 20. The external device 200 may be a cloud server. The external device 200 includes a communication unit 201, a storage unit 203, a billing unit 205, and a calculation unit 207.

The communication unit 201 receives the power consumption together with the user ID and the vehicle ID from the in-vehicle device 100, and outputs the power consumption to the calculation unit 207. Note that the communication unit 201 may receive, from the in-vehicle device 100, information such as the traveling time of the vehicle 20 and image data of an occupant of the vehicle 20, together with the information, and output the information to the calculation unit 207.

The storage unit 203 stores a reference for calculating a cost for running the vehicle 20, such as a tax amount, based on the power consumption. The reference may include a coefficient having a different value according to the traveling time, a coefficient having a different value according to the number of occupants, and the like.

The storage unit 203 stores at least one of the user ID and the vehicle ID in association with the address of the communication terminal 40. The storage unit 203 may further store information indicating whether the vehicle 20 is provided by a service such as a rental car or a share car. It is assumed that the user 30 uses not only the vehicle 20 owned by the user but also the vehicle 20 provided by such a service. In this case, since the address of the communication terminal 40 possessed by the user 30 who has driven the vehicle 20 provided by such a service cannot be specified from only the vehicle ID, the storage unit 203 communicates with the user ID. It is preferable that the address of the terminal 40 is stored in association with the address.

The calculation unit 207 refers to the storage unit 203 and calculates a tax amount as a cost for traveling of the vehicle 20 based on the calculated power consumption. Calculating section 207 outputs the calculated power consumption and tax amount to billing section 205 together with the vehicle ID and the user ID. For example, in the case where the vehicle 20 is provided by a rental car service or a car sharing service, a tax on the cost of running the vehicle 20 is charged to the user 30 who has driven the vehicle 20 by the service provider. It may be a vehicle usage fee including expenses other than the above. In this case, the business operator may pay the tax amount to the executive branch, and the business operator may charge the user 30 for the vehicle usage fee.

When the power consumption, the tax amount, the vehicle ID, and the user ID are input from the calculation unit 207, the billing unit 205 bills the user 30 who has driven the vehicle 20 for the tax amount. More specifically, the requesting unit 205 specifies the addresses of the communication terminal 40 and the in-vehicle device 100 associated with at least one of the user ID and the vehicle ID by referring to the storage unit 203, and , The billing information for billing the tax amount is transmitted to the address. The billing information may indicate a corresponding power consumption amount in addition to the tax amount. Note that the billing unit 205 may transmit the billing information to only one of the communication terminal 40 and the vehicle-mounted device 100.

FIG. 4 is a flowchart for calculating the tax amount. The flow is started when, for example, the in-vehicle device 100 detects that the power switch of the vehicle 20 is turned on, and the internal power supply of the in-vehicle device 100 is activated.

(4) The in-vehicle device 100 establishes wireless communication with the communication terminal 40 to communicate with the communication terminal 40 owned by the user 30 who has boarded the vehicle 20 (step S101). The in-vehicle device 100 reads out the user ID of the user 30 from the communication terminal 40 (Step S103).

The calculation unit 123 of the in-vehicle device 100 causes the measurement unit 101 to start measuring each electric energy (step S105), and the first measurement unit 103 and the second measurement unit 105 of the measurement unit 101 respectively use the battery 21 of the vehicle 20 And the second discharge amount to the outside of the vehicle 20 is measured.

The calculation unit 123 waits until a predetermined time, for example, midnight has elapsed (step S107: NO), and when the time has elapsed (step S107: YES), the calculation unit 123 refers to the storage unit 117, The respective power amounts measured by the measurement unit 101 are acquired during a period from the start of the measurement by the measurement unit 101 to the lapse of the time, and the vehicle 20 determines the amount of power based on the first discharge amount and the second discharge amount. The amount of consumed power is calculated (step S109). The calculating unit 123 transmits a signal related to the calculated power consumption to the external device 200 (Step S111).

When the calculation unit 207 of the external device 200 acquires a signal related to the amount of power consumption via the communication unit 201, the calculation unit 207 calculates a tax amount based on the amount of power consumption (step S113), and a billing unit together with the user ID and the vehicle ID. 205.

When the tax amount, the user ID, and the vehicle ID are input from the calculating unit 207, the claim unit 205 refers to the storage unit 203, and the communication terminal 40 and the communication terminal 40 that are associated with at least one of the user ID and the vehicle ID. The address of the vehicle-mounted device 100 is specified. The billing unit 205 transmits billing information corresponding to the tax amount to the specified address (step S115), and the flow ends.

The vehicle-mounted device 100 outputs the billing information to the vehicle 20 upon receiving the billing information from the external device 200. The user 30 confirms the tax amount or the like indicated in the billing information by operating at least one of the communication terminal 40 and, for example, an in-vehicle display of the vehicle 20. The flow is restarted after the external device 200 transmits the billing information to the communication terminal 40 and the in-vehicle device 100, that is, when the power switch of the vehicle 20 is turned on again after a predetermined time has elapsed, Repeated.

Note that even when the power switch of the vehicle 20 is turned off after the measurement by the measuring unit 101 is started in step S105 and the power consumption is calculated in step S109, the measurement is performed by the measuring unit 101. Since the measured values measured are cumulatively stored in the storage unit 117, the calculation unit 123 calculates the power consumption in a period from the start of the measurement by the measurement unit 101 to the elapse of a predetermined time. be able to.

As described above, according to the tax amount calculation system 15 of the present embodiment, the in-vehicle device 100 reads the user ID of the user 30 who runs the vehicle 20 from the communication terminal 40, and the first discharge amount from the battery 21 of the vehicle 20; Then, the amount of power consumed by the vehicle 20 is calculated by measuring the second amount of discharge to the outside of the vehicle 20 and subtracting the second amount of discharge from the first amount of discharge. Thereby, the tax amount calculation system 15 does not use the electric power of the vehicle-mounted battery of the vehicle 20 to the outside, share the vehicle 20 with a plurality of people, or use up the electric power charged to the vehicle 20 by itself. The user 30 himself / herself uses the vehicle 20 even when the vehicle 20 is run by another person or the vehicle 20 is run using the power charged by the other person without being charged by itself. Thus, the amount of power consumed by the vehicle 20 can be calculated. In addition, since the tax amount calculation system 15 measures the second discharge amount discharged to the outside of the vehicle 20 via the outside connection unit 27, only the sensor that measures the charge / discharge amount of the vehicle motor is provided in the electric vehicle.
