In the present disclosure, “power sale” includes supplying power in exchange for money, supplying power by regarding the power itself as a virtual currency, and the like. The amount of power supplied from power storage device 10 to power device 20 is also referred to as the amount of power sold. The power device 20 may supply the power sold from the power storage device 10 to, for example, a load device or a storage battery provided in a facility where the power device 20 is installed. Power device 20 may function as a charger for charging power storage device 10. In such a case, the power device 20 supplies power to the power storage device 10 from, for example, a commercial power source or a storage battery provided in a facility where the power device 20 is installed. The details of the power device 20 will be described later.

The power generation facility 30 has any device capable of generating power. For example, the power generation facility 30 may have a solar cell as described later.

In the present embodiment, the provision of the reward is performed by the power device 20. In another embodiment, the reward may be provided by an external server that can communicate with the power device 20 via a communication network such as the Internet. For example, when the user clicks the settlement start button with the application of the smartphone, the power device 20 ends the power reception operation according to the communication from the external server. The power device 20 calculates the reward of the power sold by the power storage device 10 so far and transmits the calculated reward to the external server. The external server creates a code image such as a reduced barcode or QR code (registered trademark) corresponding to the reward and transmits it to the user's smartphone. The user can receive a reduction in payment by presenting a code image displayed on the smartphone, for example, at the time of clearing of a meal or a product purchase.

Thus, the user using power system 1 can sell, for example, the power stored in power storage device 10 at any facility where power device 20 is installed. Therefore, since the opportunity which a user can sell can increase, the convenience of the technique which sells electric power improves. In addition, since the use of the power stored in power storage device 10 is promoted, the use efficiency of the power for the user is improved. Also, the user can be motivated to move to a facility where the power device 20 is installed. Thus, for example, the economic activity of the user at the facility is activated.

The operation history of the accessory is information notified from the mobile unit 40 to the power storage device 10 as described above. For example, when the control unit 15 acquires a notification of the operation history of the accessory from the mobile unit 40 via the communication unit 12, the control unit 15 may store the operation history in the storage unit 14.

The second predicted power amount may be determined, for example, that the power storage device 10 and the power device 20 are communicably connected. For example, the control unit 15 of the power storage device 10 determines a predicted value of the amount of power consumed for moving the moving body 40 from the position of the power device 20 to the position of the predetermined facility as the second predicted amount of power. It may be stored in the storage unit 14. Details of the operation of the control unit 15 that determines the second predicted power amount will be described later.

(Operation of power storage device and power device)
The operations of power storage device 10 and power device 20 will be specifically described. The operation is an operation related to the sale of power from the storage device 10 to the power device 20.

Control unit 15 of power storage device 10 stores user information. Specifically, for example, when power storage device 10 and power management device 33 are communicably connected, control unit 15 notifies of the first predicted amount of power and notification of the location information of the facility where power generation facility 30 is installed. May be acquired from the power management apparatus 33 and stored in the storage unit 14. For example, when power storage device 10 and power device 20 are communicably connected, control unit 15 obtains a notification of the operation history of mobile unit 40 and a notification of the operation history of auxiliary units from mobile unit 40, and stores unit 14 May be stored. For example, when power storage device 10 and power device 20 are communicably connected, control unit 15 may determine the second predicted amount of power and store it in storage unit 14.

Any algorithm can be employed to determine the second predicted amount of energy. For example, the control unit 15 may acquire position information of the power device 20 from the power device 20 via the communication unit 12. Control unit 15 may obtain current position information of power storage device 10 using sensor unit 13. Control unit 15 may determine the second predicted power amount based on the position information of power device 20 or the current position information of power storage device 10 and the position information of the predetermined facility included in the user information. . Specifically, the control unit 15 determines the distance between the position of the power device 20 or the storage device 10 and the position of the facility, and the fuel consumption information of the moving object 40 acquired from the moving object 40 via the communication unit 12 The second predicted power amount may be determined based on.

The control unit 15 may further determine the second predicted amount of power based on the operation history of the moving body 40. For example, the control unit 15 may increase the second predicted power amount as the value of the above-described score indicated in the driving history of the mobile object 40 or the average value in a certain period is lower. Control unit 15 may further determine the second predicted amount of power based on the operation history of the accessory provided to mobile unit 40. For example, the control unit 15 may increase the second predicted power amount as the value of the power consumption of the accessory indicated in the operation history of the accessory or the average value or the integrated value in a predetermined period is larger.

For example, when power storage device 10 and power device 20 are communicably connected, control unit 15 determines the margin power amount based on the above-described user information. The margin power amount may be determined based on at least one of the first predicted power amount and the second predicted power amount. For example, the margin power amount may be determined to substantially match the first predicted power amount, the second predicted power amount, or the sum of the first predicted power amount and the second predicted power amount. The margin power amount is determined to be substantially equal to a value obtained by adding a predetermined power amount to the first predicted power amount, the second predicted power amount, or the sum of the first predicted power amount and the second predicted power amount. It is also good. The predetermined amount of power may be, for example, the remaining capacity when the output voltage of the storage battery 11 becomes the discharge termination voltage. The remaining capacity when the output voltage of the storage battery 11 becomes the discharge termination voltage may be determined in advance by, for example, experiment or simulation.

Control unit 15 subtracts the margin power amount from the remaining capacity of storage battery 11 of power storage device 10 to determine the upper limit power amount. The control unit 15 permits power sale up to the upper limit power amount. Specifically, the control unit 15 may end the power sale when the amount of power sold reaches the upper limit power amount after the start of the power sale. For example, the control unit 15 starts selling electricity to the power device 20. When the power sale ends, the control unit 24 of the power device 20 gives the user a reward according to the amount of power sale power.

FIG. 6 is a sequence diagram showing operations of power storage device 10 and power device 20.

Step S100: The storage device 10 stores user information in association with the storage device ID.

Step S101: The power storage device 10 determines the margin power amount based on the user information.

Step S102: The power storage device 10 subtracts the margin power amount from the remaining capacity of the storage battery 11 to determine the upper limit power amount.

Step S103: The power storage device 10 permits power sale up to the upper limit electric energy.

Step S104: The power storage device 10 starts selling electricity to the power device 20.

Step S105: When the power sale ends, the power device 20 gives the user a reward according to the amount of power sale electricity.

As described above, in power system 1, power storage device 10 determines the margin power amount based on the user information associated with power storage device 10. Power storage device 10 permits power sale up to the upper limit power amount obtained by subtracting the margin power amount from the remaining capacity of storage battery 11. According to this configuration, the remaining capacity of the storage battery 11 after the end of the power sale becomes equal to or higher than the margin power amount determined according to the user. Therefore, the user does not have to determine the amount of power sale electric power in consideration of the remaining capacity of the storage battery 11 after the end of the power sale. Therefore, since the burden of the user who determines the electric power sales amount is reduced, the convenience of the technology of selling electric power is improved.

For example, the margin power amount may be determined based on a first predicted power amount which is a predicted value of the power amount consumed in a predetermined time zone in a predetermined facility associated with power storage device 10. According to this configuration, for example, when power is supplied to the facility from the power storage device 10 after power sale, there is a probability that power consumed in the time zone in the facility can be supplied from the power storage device 10 after power sale. To increase. For example, the probability that power consumed at night in the user's home can be supplied from the power storage device 10 after sale increases. For this reason, the user does not have to determine the amount of power sale electric power in consideration of the power consumed in the time zone in the facility. Therefore, since the burden on the user who determines the electric power sales amount is reduced, the convenience of the technology for selling electric power is further improved.

For example, the margin power amount is based on a second predicted power amount that is a predicted value of the power amount consumed for moving the mobile unit 40 from the position of the power device 20 to the position of the predetermined facility associated with the power storage device 10. May be determined. According to this configuration, for example, after the end of the power sale, the occurrence of inconvenience such as the inability of the mobile body 40 to move to the facility due to the shortage of the remaining capacity of the power storage device 10 is reduced. For example, the occurrence of inconveniences such as the user not being able to return to the home by the mobile unit 40 after power sale is reduced. For this reason, the user does not have to determine the amount of power sold in consideration of the amount of power consumed by the mobile unit 40 to move to the facility. Therefore, since the burden on the user who determines the electric power sales amount is reduced, the convenience of the technology for selling electric power is further improved.

For example, the margin power amount may be corrected based on the correction value acquired from the server of the management company via a communication network such as the Internet. Specifically, the power device 20 notifies the server of the margin power amount determined as described above. For example, if it is determined that the notified margin power amount is not appropriate because, for example, the user has made a detour after the end of the power sale by the user in the past, the server corrects the power device 20 by a predetermined correction value. To correct the margin power amount so that the power sales amount is not excessive. As the case where the correction is necessary, when the weather after moving the moving body 40 to the power generation facility 30 is bad and the amount of predicted chargeable is small, and the facility to which the moving body 40 moves is on a regular holiday The case etc. may be mentioned.

Although the present disclosure has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various changes and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present disclosure.
