## 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 promote external charging, suppress external charging, or carry out external power feed in accordance with the made schedule. The server obtains power run-out information that indicates power run-out risk for each power storage and carries out at least one of selection of the power storage and making of the schedule in accordance with a type of a request based on the obtained power run-out information.

## Claims

### Claim 1

A server usable 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 promote the external charging, suppress the external charging, or carry out the external power feed in accordance with the made schedule, wherein
the server
obtains power run-out information that indicates power run-out risk for each power storage, and
carries out at least one of selection of the power storage and making of the schedule in accordance with a type of a request based on the obtained power run-out information.

### Claim 2 (depends on 1)

The server according to claim 1, wherein
when the selector selects a power storage requested to suppress the external charging or carry out the external power feed by the request processor, the selector preferentially sequentially selects the power storage lower in power run-out risk.

### Claim at position 3 (depends on 1)

The server according to claim 1, wherein
when the scheduler makes a schedule for issuing a request for suppressing the external charging or carrying out the external power feed, the scheduler makes the schedule such that a power storage lower in power run-out risk among the selected power storages starts earlier the request for suppressing the external charging or carrying out the external power feed.

### Claim 4 (depends on 1)

The server according to claim 1, wherein
when the selector selects a power storage requested to promote the external charging by the request processor, the selector preferentially sequentially selects the power storage higher in power run-out risk.

### Claim 5 (depends on 1)

The server according to claim 1, wherein
when the scheduler makes a schedule for issuing a request for promoting the external charging, the scheduler makes the schedule such that a power storage higher in power run-out risk among the selected power storages starts earlier the request for promoting the external charging.

### Claim 6 (depends on 1)

The server according to claim 1, wherein
the plurality of power storages are mounted on a plurality of mobile bodies, respectively, and
the server comprises a first estimator that estimates the power run-out risk for each mobile body based on at least one of long-distance travel capability, charging capability, a current position, a next travel distance, next departure time, a next travel route, and remaining energy for traveling tor each mobile body.

### Claim 7

A server usable 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 plurality of power storages being mounted on a plurality of mobile bodies, respectively, 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 promote the external charging, suppress the external charging, or carry out the external power feed in accordance with the made schedule, wherein
the server
obtains information on at least one of long-distance travel capability, charging capability, a current position, a next travel distance, next departure time, a next travel route, and remaining energy for traveling for each mobile body, and
carries out at least one of selection of the power storage and making of the schedule in accordance with a type of a request based on the obtained information.

### Claim 8 (depends on 1)

A power management system comprising:
the server according to claim 1; and
a plurality of mobile bodies,
the plurality of power storages being mounted on the plurality of mobile bodies, respectively, wherein
each of the plurality of mobile bodies
includes a second estimator that estimates the power run-out risk of each of the plurality of mobile bodies based on at least one of long-distance travel capability, charging capability, a current position, a next travel distance, next departure time, a next travel route, and remaining energy for traveling of the mobile body, and
transmits the power run-out risk of the mobile body estimated by the second estimator to the server.

### Claim 9 (depends on 1)

A power management system comprising:
the server according to claim 1;
a plurality of vehicles, the plurality of power storages being mounted on the plurality of vehicles, respectively;
a plurality of power facilities electrically connectable to the plurality of vehicles, respectively; and
a power grid that supplies electric power to each of the plurality of power facilities, wherein
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 promote the external charging, suppress the external charging, or carry out the external power feed in accordance with the schedule.
