Abstract

[PROBLEM] To provide a technology of effectively using supplied electric power through adjustment of a charge schedule period of an EV.

[SOLVING MEANS] A charge period adjusting apparatus according to embodiments includes an acquiring section and a control section. The acquiring section is configured to acquire a power supply schedule amount of an electric system including a charger connected during charge of an electric vehicle. The control section is configured to set a charge period such that the electric vehicle is charged by the charger in a time frame in which the power supply schedule amount acquired by the acquiring section exceeds a threshold value.

Claims

1. A charge period adjusting apparatus comprising:

an acquiring section configured to acquire a scheduled amount of power supply of an electric system including a charger connected during charge of an electric vehicle; and

a control section configured to set a charge period such that the electric vehicle is charged by the charger in a first time frame in which the scheduled amount of power supply acquired by the acquiring section exceeds a threshold value,

wherein the scheduled amount of power supply is a predicted amount of power per unit time to be supplied, and

wherein the control section derives the first time frame from the scheduled amount of power supply and makes a schedule so as to perform charging in the first time frame, and when the charging is not completed in the first time frame, a remaining charging is scheduled to be performed at a beginning of a chargeable time of the electric vehicle.

2. The charge period adjusting apparatus according to claim 1, wherein the acquiring section is further configured to acquire a use schedule period of the electric vehicle, to acquire information about a scheduled running distance or a destination of the electric vehicle during the use, and to acquire a remaining charge level of the electric vehicle, and

the control section is configured to calculate a period required for charge of the electric vehicle based on the information about the scheduled running distance or the destination and the remaining charge level, and to determine whether or not charge is completed until the use schedule period starts.

3. The charge period adjusting apparatus according to claim 1, wherein the acquiring section is configured to acquire a scheduled amount of power supply including a power amount scheduled to be supplied from renewable energy.

4. The charge period adjusting apparatus according to claim 1, wherein the acquiring section is further configured to acquire a scheduled time frame in which power supply is stopped in the electric system, and

the control section is configured to set the charge period such that the charge is not performed in the scheduled time frame in which the power supply is stopped.

5. The charge period adjusting apparatus according to claim 2, wherein the control section is configured to set the charge period assuming that the electric vehicle is charged by a faster charger configured to charge faster than the charger when it is determined that the charge is not completed until the use scheduled period.

6. A charge system comprising:

a predicting apparatus configured to calculate an amount of power supply scheduled to be supplied from renewable energy; and

a charge period adjusting apparatus configured to include the amount of power supply calculated in the predicting apparatus, to acquire a scheduled amount of power supply of an electric system including a charger connected during charge of an electric vehicle, and to set a charge period such that the electric vehicle is charged by the charger in a first time frame in which the scheduled amount of power supply exceeds a threshold value,

wherein the scheduled amount of power supply is a predicted amount of power per unit time to be supplied, and

wherein the charge period adjusting apparatus derives the first time frame from the scheduled amount of power supply and makes a schedule so as to perform charging in the first time frame, and when the charging is not completed in the first time frame, a remaining charging is scheduled to be performed at a beginning of a chargeable time of the electric vehicle.

7. The charge system according to claim 6, further comprising:

a terminal apparatus configured to acquire a use schedule period of the electric vehicle, and information about a scheduled running distance or a destination of the electric vehicle during the use,

wherein the charge period adjusting apparatus is further configured to acquire the use schedule period of the electric vehicle, and the information about the scheduled running distance or the destination acquired in the terminal apparatus, to acquire a remaining charge level of the electric vehicle from the electric vehicle, to calculate a period required for charge of the electric vehicle based on the information about the scheduled running distance or the destination and the remaining charge level, and to determine whether or not charge is completed until the use schedule period starts.

8. The charge system according to claim 6, wherein the charge period adjusting apparatus is further configured to acquire a scheduled time frame in which power supply is stopped in the electric system, and to set the charge period such that the charge is not performed in the scheduled time frame in which the power supply is stopped.

9. The charge system according to claim 7, wherein the charge period adjusting apparatus is configured to set the charge period assuming that the electric vehicle is charged by a faster charger configured to charge faster than the charger when it is determined that the charge is not completed until the use schedule period.

10. A non-transitory computer readable medium having stored thereon a charge period adjusting program for causing a computer to perform processing of:

acquiring scheduled amount of power supply of an electric system including a charger connected during charge of an electric vehicle, the scheduled amount of power supply being a predicted amount of power per unit time to be supplied; and

setting a charge period such that the electric vehicle is charged by the charger in a time frame in which the scheduled amount of power supply exceeds a threshold value,

deriving the first time frame from the scheduled amount of power supply to make a schedule so as to perform charging in the first time frame, and

scheduling for a remaining charging to be performed at a beginning of a chargeable time of the electric vehicle, when the charging is not completed in the first time frame.

11. The non-transitory computer readable medium according to claim 10, for causing a computer to further perform processing of:

acquiring a use schedule period of the electric vehicle;

acquiring information about a scheduled running distance or a destination of the electric vehicle during the use;

acquiring a remaining charge level of the electric vehicle;

calculating a period required for charge of the electric vehicle based on the information about the scheduled running distance or the destination and the remaining charge level; and

determining whether or not charge is completed until the use schedule period starts.

12. The non-transitory computer readable medium according to claim 10, wherein the acquiring includes processing of acquiring a scheduled amount of power supply including a power amount scheduled to be supplied from renewable energy.

13. The non-transitory computer readable medium according to claim 10, for causing a computer to further perform processing of:

acquiring a scheduled time frame in which power supply is stopped in the electric system; and

setting the charge period such that the charge is not performed in the scheduled time frame in which the power supply is stopped.

14. The non-transitory computer readable medium according to claim 11, for causing a computer to further perform processing of setting the charge period assuming that the electric vehicle is charged by a faster charger configured to charge faster than the charger when it is determined that the charge is not completed until the use schedule period.
