(Step S23) The control unit 130 specifies the date from the time information of the electric energy information. The specified date is the accumulation date. The control unit 130 determines whether or not the information settled on the accumulation date exists in the settlement information.
When the condition of step S23 is satisfied, the control unit 130 advances the process to step S24. If the condition of step S23 is not satisfied, the control unit 130 advances the process to step S31.

(Step S24) The control unit 130 acquires the store name of the payment information corresponding to the accumulation date.
(Step S25) The control unit 130 detects the store name, which is the name of the store that sold the charged electricity, based on the map information stored in the storage unit 110 and the position information included in the electric energy amount information. .. The store name is also referred to as a second store name.
Further, the control unit 130 detects the store name, which is the name of the store that sold the charged electricity, based on the map information stored in the external device such as the cloud server and the location information included in the fuel information. You may.

(Step S26) The control unit 130 determines whether or not the store name acquired in step S24 and the store name detected in step S25 match.
When the condition of step S26 is satisfied, the control unit 130 advances the process to step S27. If the condition of step S26 is not satisfied, the control unit 130 advances the process to step S31.
(Step S27) The control unit 130 calculates the average book value using the equation (1).

The total book value will be described later. The initial value of the total book value is 0. Further, the total book value of the formula (1) is also referred to as an amount corresponding to the second storage amount.
The settlement amount of the formula (1) is the settlement amount included in the settlement information. Alternatively, it is the settlement amount entered in step S32 described later. The stored amount of the formula (1) is the stored amount included in the electric energy information. Further, the stored amount of the formula (1) is also referred to as a first stored amount. The total amount of the total book value and the settlement amount is referred to as the remaining total.
The control unit 130 stores the average book value in the storage unit 110.

The average book value is calculated based on the settlement amount, which is the purchase amount paid at the first store having the same name as the store name, the amount corresponding to the second storage amount, and the first storage amount.

FIG. 7 is a flowchart (No. 2) showing the calculation process of the average book value of the first embodiment.
(Step S31) The control unit 130 makes an inquiry to the user. Specifically, since the control unit 130 cannot calculate the average book value, the control unit 130 prompts the user to input the settlement amount when the user purchases electric energy.

(Step S32) The control unit 130 determines whether or not the settlement amount has been input. When the settlement amount is input, the control unit 130 advances the process to step S27. If the settlement amount is not input, the control unit 130 ends the process.

FIG. 8 is a sequence diagram showing a calculation process of the total book value of the first embodiment. Further, the portable device 100 and the vehicle-mounted device 200 periodically execute the process shown in FIG.
(Step ST111) The acquisition unit 230 of the in-vehicle device 200 acquires the amount of electricity stored from the charge measurement sensor 11.

(Step ST113) The control unit 130 of the portable device 100 calculates the total book value using the equation (2).

The control unit 130 can calculate the consumption amount of the equation (2) by the difference between the electricity storage amount included in the electric energy amount information acquired in step S21 and the electricity storage amount acquired by the acquisition unit 230 in step ST111. The total book value of equation (2) is also referred to as the second amount. The total book value of the formula (2) may be considered as an amount corresponding to the second storage amount.
The remaining total of the formula (2) is the remaining total calculated in step S27 before the execution of step ST113. The average book value of the formula (2) is the average book value calculated in step S27 before step ST113 is executed.

The control unit 130 stores the total book value in the storage unit 110. The total book value stored in the storage unit 110 is used when step S27 is executed after step ST113.

Next, a case where the average book value and the total book value are displayed on the display of the portable device 100 will be described.
9 (A) and 9 (B) are diagrams showing specific examples of the display contents of the first embodiment. The output unit 140 outputs the average book value and the total book value stored in the storage unit 110 to the display of the portable device 100. FIG. 9A shows a state in which the average book value and the total book value are displayed on the display of the portable device 100.

A modified example of the first embodiment (No. 1).
In the modified example (No. 1) of the first embodiment, the case where the portable device 100 calculates the average book value using the receipt 20 will be described.
The communication unit 120 receives the electric energy information from the in-vehicle device 200. The reading unit 150 reads the contents of the receipt 20 on which the payment amount is described. For example, the payment information described on the receipt 20 is a store name, a payment date and time, a payment amount, and the like.
The control unit 130 calculates the average book value using the equation (1). The settlement amount in the formula (1) is the amount read from the receipt 20 by the reading unit 150. The control unit 130 stores the average book value in the storage unit 110.
In this way, the portable device 100 can calculate the average book value using the receipt 20.

A modified example of the first embodiment (No. 2).
In step S22, the case where the mobile device 100 acquires the payment information has been described. Here, since the payment information does not include the information when the electric energy is purchased, the average book value may not be calculated. For example, the average book value cannot be calculated because the settlement information does not include the time information corresponding to the accumulation date. Further, for example, since the store name of the payment information is unknown or the store name of the payment information cannot be inferred as the power supply equipment, No is determined in step S26. Then, since No is determined in step S26, the average book value cannot be calculated. Even in such a case, the case where the portable device 100 can calculate the average book value will be described.

FIG. 10 is a flowchart showing a calculation process of the average book value of the modified example of the first embodiment. The process of FIG. 10 is executed when No in step S23 or No in step S26.

In this way, the control unit 130 can calculate the payment amount when the payment information received by the communication unit 120 does not include the purchase date or the name of the first store.

A modified example of the first embodiment (No. 3).
The user can charge the power storage device 12 by using the flat-rate service. For example, the user can charge the power storage device 12 as many times as he / she wants for a month by paying a predetermined amount of money.

(Step S51) The control unit 130 detects the store that sold the charged electricity based on the map information stored in the storage unit 110 and the position information included in the electric energy amount information. The store is also called a third store.
Further, the control unit 130 may detect the store based on the map information stored in an external device such as a cloud server and the location information included in the electric energy information.

(Step S52) The control unit 130 determines whether or not the store detected in step S51 is a store that has a contract to receive a flat-rate service.

As described above, in steps S73 to 77, the control unit 240 detects that the accumulation date and the purchase date match, detects the second store name based on the map information and the location information, and performs the second. The average book value is calculated based on the settlement amount, which is the purchase amount paid at the first store having the same name as the store name, the amount corresponding to the second storage amount, and the first storage amount.

FIG. 18 is a flowchart (No. 2) showing the calculation process of the average book value of the third embodiment.
(Step S81) The control unit 240 makes an inquiry to the user. Specifically, since the control unit 240 cannot calculate the average book value, it prompts the user to input the settlement amount when the user purchases electric energy.
(Step S82) The control unit 240 determines whether or not the settlement amount has been input. When the settlement amount is input, the control unit 240 proceeds to the process in step S77. If the settlement amount is not input, the control unit 240 ends the process.

The control unit 240 stores the total book value in the storage unit 210. The total book value stored in the storage unit 210 is used when step S77 is executed after step S92.

Next, a case where the average book value and the total book value are displayed on the display of the in-vehicle device 200 will be described.
FIG. 20 is a diagram showing a specific example of the display contents of the third embodiment. The output unit 250 outputs the average book value and the total book value stored in the storage unit 210 to the display of the vehicle-mounted device 200.

Further, for example, since the store name of the payment information is unknown or the store name of the payment information cannot be inferred as the power supply equipment, No is determined in step S76. Then, since No is determined in step S76, the average book value cannot be calculated. Even in such a case, the case where the in-vehicle device 200 can calculate the average book value will be described. If the in-vehicle device 200 is No in step S73, or if No in step S76, the in-vehicle device 200 executes the subsequent processing. The control unit 240 detects the unit price of electricity when the electric energy is purchased from the network based on the time information included in the electric energy information.

When the average book value is lower than the electric power unit price, the control device 600 may supply the electric energy stored in the power storage device 12 to the home. Then, the control device 600 stops the supply of electric energy when the amount of electricity stored is the minimum. Further, when the average book value is higher than the electric power unit price, the control device 600 supplies power to the electric vehicle 10 via the electric power network.
