Abstract

A method, for use in a charging system including a vehicle in which a battery is installed, a charging facility, and an information terminal, for changing a charging schedule of the battery after creating the charging schedule without re-inserting a charging cable includes: receiving a request for a change of the charging schedule; acquiring, from the charging facility, a charging parameter applied in a case where the charging schedule is changed in response to the request for the change of the charging schedule as received; and creating a charging schedule after the change using the charging parameter acquired from the charging facility.

Claims

1. An apparatus for changing a charging schedule of a battery installed in a vehicle, the apparatus comprising:

a communication device, installed in the vehicle, to receive a request for a change of said charging schedule;

acquire, from a charging control apparatus in a charging facility side, a charging parameter applied in a case that said charging schedule is changed; and

a control device, installed in the vehicle, to create a new charging schedule after the change using a new charging parameter acquired from said charging control apparatus in said charging facility side, wherein

said communication device transmits said new charging schedule to said charging control apparatus in said charging facility side, and receives, from said charging control apparatus in said charging facility side, a response indicating whether implementation of said new charging schedule is possible.

2. The apparatus according to claim 1, wherein

said control device suspends charging after said charging schedule is received.

3. The apparatus according to claim 1, wherein

said communication device receives the request for the change of said charging schedule from an information input and output apparatus that communicates with said vehicle.

4. The apparatus according to claim 1, wherein

said communication device receives, from said charging control apparatus, notification that an event requiring the change of said charging schedule has occurred instead of receiving the request for the change of said charging schedule.

5. The apparatus according to claim 1, wherein

in a case of obtaining user'"'"'s approval on whether the charging parameter acquired from said charging control apparatus is applied to change the charging schedule, a change detail information is notified to an information terminal.

6. The apparatus according to claim 1, wherein

said charging parameter satisfies a condition before the change of the charging schedule.

7. The apparatus according to claim 1, wherein

in a case that said charging parameter does not satisfy a condition before the change of the charging schedule, said charging parameter includes a flag for selection of whether to approve the change of the charging schedule.

10. The apparatus according to claim 1, wherein

said control device suspends charging after the request for a change of said charging schedule is received.

8. A charging control apparatus in a charging facility side, the charging control apparatus comprising:

a device to communicate with a vehicle in which a battery is installed; and

a power feeding control device to control feeding of power to said battery in accordance with a charging schedule, wherein

when said communication device receives a request for a change of said charging schedule, said communication device notifies said vehicle of a charging parameter applied in a case that said charging schedule is changed,

said communication device transmits a response indicating whether implementation of the charging schedule is possible to said vehicle, the charging schedule being notified from said vehicle as a response to said charging parameter.

9. An information input and output apparatus for communicating with a vehicle in which a battery is installed, the information input and output apparatus

when a change of a charging schedule of said battery is input, to notify said vehicle of a request for the change of the charging schedule;

to acquire information on a charging state of said battery from said vehicle;

to acquire, from a charging control apparatus in a charging facility side that feeds power to said battery, a charging parameter applied in a case that said charging schedule is changed;

to create a new charging schedule after the change using the information on the charging state of said battery as acquired and a new charging parameter; and

to transmit said new charging schedule to said charging control apparatus in said charging facility side, and receive, from said charging control apparatus in said charging facility side, a response indicating whether implementation of said new charging schedule is possible,

to convert information on said new charging parameter into at least one of a delay time of departure and a power rate, and output the converted information, if implementation of said new charging schedule is possible, and

to output information indicating implementation of the charging schedule is not possible, if implementation of said new charging schedule is not possible.
