Abstract

A charging schedule creation unit creates a charging schedule of a power storage device by an external power supply. A charging control unit executes charging control of the power storage device in accordance with the charging schedule. A condition determination unit turns on a charging continuation flag to be output to the charging control unit when a predetermined charging continuation permitting condition holds in the case where charging is not completed in accordance with the charging schedule. When the charging continuation flag is on, the charging control unit executes charging control such that charging is continued even after a charging end timing in accordance with the charging schedule.

Claims

1. A charging control device for charging a power storage device mounted on a vehicle by a power supply outside the vehicle, comprising:

a creation unit creating a charging schedule of said power storage device by said power supply; and

a control unit executing charging control of said power storage device in accordance with said charging schedule,

said control unit executing said charging control such that charging is continued even after a charging end timing in accordance with said charging schedule when a predetermined charging continuation permitting condition holds in the case where charging is not completed in accordance with said charging schedule,

wherein said charging continuation permitting condition holds in the case where an air conditioner for adjusting a vehicle interior temperature is operated during charging.

2. The charging control device according to claim 1, wherein said control unit executes said charging control such that charging is continued even after a charging end time in accordance with said charging schedule when said predetermined charging continuation permitting condition holds in the case where charging is not completed at said charging end time.

3. The charging control device according to claim 1, wherein said control unit executes said charging control without following said charging schedule when said predetermined charging continuation permitting condition holds in the case where charging is not completed in accordance with said charging schedule.

4. The charging control device according to claim 1, wherein said control unit terminates charging at said charging end timing when said predetermined charging continuation permitting condition does not hold.

5. The charging control device according to claim 1, wherein said charging continuation permitting condition holds in the case where charging is interrupted due to a power failure of said power supply.

6. The charging control device according to claim 1, wherein said charging continuation permitting condition holds in the case where there is a change in setting of electric power supplied from said power supply.

7. The charging control device according to claim 1, further comprising an input unit for allowing a user to select whether or not charging is continued even after said charging end timing.

8. A vehicle comprising the charging control device as defined in claim 1.

9. A charging control method for charging a power storage device mounted on a vehicle by a power supply outside the vehicle, comprising the steps of:

creating a charging schedule of said power storage device by said power supply; and

executing charging control of said power storage device in accordance with said charging schedule,

said step of executing said charging control including the step of continuing charging even after a charging end timing in accordance with said charging schedule when a predetermined charging continuation permitting condition holds in the case where charging is not completed in accordance with said charging schedule,

wherein said charging continuation permitting condition holds in the case where an air conditioner for adjusting a vehicle interior temperature is operated during charging.

10. The charging control method according to claim 9, wherein said step of continuing charging includes the step of continuing charging even after a charging end time in accordance with said charging schedule when said predetermined charging continuation permitting condition holds in the ease where charging is not completed at said charging end time.

11. The charging control method according to claim 9, wherein said charging continuation permitting condition holds in the case where charging is interrupted due to a power failure of said power supply.

12. The charging control method according to claim 9, wherein said charging continuation permitting condition holds in the case where there is a change in setting of electric power supplied from said power supply.

13. The charging control method according to claim 9, further comprising the step for allowing a user to select whether or not charging is continued even after said charging end timing.
