Abstract

A power management system includes a plurality of power storages and a server. The server includes a selector that selects at least one of the plurality of power storages, a scheduler that makes a schedule for the selected power storage, and a request processor that requests a user of the selected power storage to control at least one of external charging and external power feed in accordance with the made schedule. The server obtains desire information that indicates a desire level (priority on battery life/priority on an incentive) and carries out at least one of selection of the power storage and making of the schedule based on the obtained desire information.

First claim

What is claimed is:

1 . A power management system comprising:
a plurality of power storages; and a server, each of the plurality of power storages carrying out at least one of external charging and external power feed, the external charging being charging of the power storage with electric power supplied from outside, the external power feed being supply of electric power from the power storage to outside, the server including
a selector that selects at least one of the plurality of power storages,
a scheduler that makes a schedule for the selected power storage, and
a request processor that requests a user of the selected power storage to control at least one of the external charging and the external power feed in accordance with the made schedule, wherein
the server
obtains for each power storage, desire information that indicates at least one of a first desire level and a second desire level, the first desire level indicating a level of user's desire for suppression of deterioration of the power storage, the second desire level indicating a level of user's desire for acquisition of an incentive for meeting a request, and
carries out at least one of selection of the power storage and making of the schedule based on the obtained desire information.

2 . The power management system according to claim 1 , wherein
the desire information is at least one of
information that indicates the level of the user's desire for suppression of deterioration of the power storage by any of desiring and not desiring suppression of deterioration of the power storage, and
information that indicates the level of the user's desire for acquisition of the incentive by any of desiring and not desiring acquisition of the incentive.

3 . The power management system according to claim 1 , wherein
when the selector selects a power storage of which a user is requested to carry out external charging by the request processor, the selector preferentially sequentially selects the power storage lower in the first desire level or the power storage higher in the second desire level.

4 . The power management system according to claim 1 , wherein
when the selector selects a power storage of which a user is requested to carry out external power feed by the request processor, the selector preferentially sequentially selects the power storage higher in the first desire level or the power storage higher in the second desire level.

5 . The power management system according to claim 1 , wherein
when the selector selects a power storage of which a user is requested to carry out external power feed by the request processor, the selector preferentially sequentially selects the power storage higher in the first desire level or the power storage lower in the second desire level from among power storages that satisfy a prescribed condition.

6 . The power management system according to claim 5 , wherein
the server manages for each user, a unit price of the incentive given to the user that meets the request from the request processor, and increases the unit price of the incentive for the user lower in the first desire level or the user higher in the second desire level.

7 . The power management system according to claim 1 , wherein
the plurality of power storages are mounted on a plurality of mobile bodies, respectively, the server obtains next departure time for each mobile body, each of the plurality of mobile bodies moves with electric power stored in the power storage, and when the scheduler makes a charging schedule for a mobile body including the selected power storage, the scheduler makes the charging schedule to make a time lag between charging end time and the next departure time smaller in a mobile body of a user higher in the first desire level or a user lower in the second desire level.

8 . The power management system according to claim 1 , wherein
the selector sets an upper limit value of the number of times of charging per unit period for each power storage based on the desire information, and excludes a power storage of which the number of times of charging per unit period has exceeded the upper limit value from candidates for selection.

9 . The power management system according to claim 1 , further comprising a plurality of portable terminals carried by respective users of the plurality of power storages, wherein
each of the plurality of portable terminals accepts input from the user of the power storage, and when the desire information is input by the user of the power storage, each of the plurality of portable terminals transmits the input desire information to the server.

10 . The power management system according to claim 1 , wherein
the plurality of power storages are mounted on a plurality of mobile bodies, respectively, the power management system further comprises a plurality of user terminals mounted on the plurality of mobile bodies, respectively, and each of the plurality of user terminals accepts input from the user of the power storage, and when the user of the power storage inputs the desire information, each of the plurality of user terminals transmits the input desire information to the server.

11 . The power management system according to claim 1 , wherein
the plurality of power storages are mounted on a plurality of vehicles, respectively, the power management system further comprises:
a plurality of power facilities electrically connectable to the plurality of vehicles; and
a power grid that supplies electric power to each of the plurality of power facilities, and
the request processor transmits a signal to at least one of communication equipment mounted on the vehicle and a portable terminal carried by a user of the vehicle, the signal requesting the user of the vehicle to control at least one of the external charging and the external power feed in accordance with the schedule.

12 . A server included in a power management system including a plurality of power storages, each of the plurality of power storages carrying out at least one of external charging and external power feed, the external charging being charging of the power storage with electric power supplied from outside, the external power feed being supply of electric power from the power storage to outside, the server comprising:
a selector that selects at least one of the plurality of power storages; a scheduler that makes a schedule for the selected power storage; and a request processor that requests a user of the selected power storage to control at least one of the external charging and the external power feed in accordance with the made schedule, wherein the server
obtains for each power storage, desire information that indicates at least one of a first desire level and a second desire level, the first desire level indicating a level of user's desire for suppression of deterioration of the power storage, the second desire level indicating a level of user's desire for acquisition of an incentive for meeting a request, and
carries out at least one of selection of the power storage and making of the schedule based on the obtained desire information.
