Abstract

According to one embodiment, a system manages energy between a charge/discharge facility positioned at each of points and electric vehicles to travel among the points. The system includes an electric vehicle sign-in unit, a route information acquisition unit, and a facility usage scheduling unit. The electric vehicle sign-in unit is configured to dynamically sign in and sign out an electric vehicle among the electric vehicles. The route information acquisition unit is configured to acquire a route information representing a traveling schedule of the electric vehicle being signed in. The facility usage scheduling unit is configured to generate a facility usage schedule representing a charge/discharge schedule of the charge/discharge facility at each point, by using the route information.

Claims

1. A system for managing energy between a charge/discharge facility positioned at each of points and electric vehicles to travel among the points, comprising:

an electric vehicle sign-in unit configured to dynamically sign in and sign out an electric vehicle among the electric vehicles;

a route information acquisition unit configured to acquire a route information representing a traveling schedule of the electric vehicle being signed in; and

a facility usage scheduling unit configured to generate a facility usage schedule representing a charge/discharge schedule of the charge/discharge facility at each point, by using the route information.

2. The system according to claim 1, wherein

the facility usage scheduling unit generates a first facility usage schedule including points for the signed-in electric vehicles to charge, and a charge/discharge energy or a charge/discharge time of the charge/discharge facility at the points, by using estimation values of a traveling time of the electric vehicle among the points and estimation values of energy consumed by the electric vehicle'"'"'s traveling.

3. The system according to claim 2, further comprising:

a notification unit configured to notify the first facility usage schedule to the signed-in electric vehicles.

4. The system according to claim 1, wherein

the facility usage scheduling unit generates a second facility usage schedule including upper limits of chargeable energy, upper limits of chargeable power, or upper limits of a charge time for the signed-in electric vehicles at the charge/discharge facility.

5. The system according to claim 1, wherein

the charge/discharge facility at apart or all of the points includes a battery facility, and

the facility usage scheduling unit generates a third facility usage schedule including target values of charge/discharge energy or target values of stored battery energy of the battery facility at each time slot.

6. The system according to claim 4, further comprising:

a notification unit configured to notify the charge/discharge facility of the second facility usage schedule.

7. The system according to claim 1, wherein

the route information acquisition unit acquires the route information at a timing when the electric vehicle sign-in unit signs in the electric vehicle or a timing when the signed-in electric vehicle passes pre-defined specific spots.

8. The system according to claim 1, further comprising:

a route information estimation unit configured to estimate the route information of the electric vehicle, based on a location where the electric vehicle is signed in;

the route information acquisition unit acquires the route information estimated by the route information estimation unit.

9. The system according to claim 3, wherein

the facility usage scheduling unit reschedules the facility usage schedule by setting a part or all of the facility usage schedule as a constraint condition, after the notification unit notifies the electric vehicle of the facility usage schedule.

10. A method for managing energy between a charge/discharge facility positioned at each of points and electric vehicles to travel among the points, comprising:

dynamically executing sign-in and sign-out of an electric vehicle among the electric vehicles;

acquiring a route information representing a traveling schedule of the electric vehicle being signed in; and

generating a facility usage schedule representing a charge/discharge schedule of the charge/discharge facility at each point, by using the route information.
