Abstract

A vehicle-side executes a program including the steps of, if setting information is input, storing a charging schedule, and if a prescribed period of time has passed, performing an update process, performing a notification process, and if a charging cable is being connected, performing a reservation charging process.

Claims

1. A vehicle comprising:

a rotating electric machine mounted on the vehicle;

a power storage device for supplying electric power to said rotating electric machine; and

a control device for receiving information about a charging schedule of said power storage device from a device capable of receiving information about said charging schedule, creating said charging schedule based on a state of said vehicle, and when said charging schedule created based on the state of said vehicle and said charging schedule inputted do not match, notifying a user of said vehicle that they do not match.

2. The vehicle according to claim 1, wherein

when information about a plurality of charging schedules is received from a plurality of said devices, said control device charges said power storage device using an external power supply in accordance with a latest charging schedule out of said plurality of charging schedules.

3. The vehicle according to claim 2, wherein

said control device selects a last received charging schedule out of said plurality of charging schedules as said latest charging schedule.

4. The vehicle according to claim 2, wherein

said control device selects a last created charging schedule out of said plurality of charging schedules as said latest charging schedule.

5. The vehicle according to claim 2, wherein

said control device allows charging and discharging of said power storage device within a range where completion of the charging in accordance with said latest charging schedule is ensured.

6. The vehicle according to claim 2, wherein

said control device performs, when a time measured by at least one of said plurality of devices is incorrect, a process of correcting said time.

7. A charging apparatus for performing charging control on a power storage device of a vehicle using a power supply outside of said vehicle, said vehicle including a rotating electric machine and said power storage device for supplying electric power to said rotating electric machine, said charging apparatus comprising:

an input device for receiving information about a charging schedule of said power storage device from a device; and

a control device for receiving information about said charging schedule of said power storage device from said device, creating said charging schedule based on a state of said vehicle, and when said charging schedule created based on the state of said vehicle and said charging schedule inputted do not match, notifying a user of said vehicle that they do not match.

8. The charging apparatus according to claim 7, wherein

when information about a plurality of charging schedules is received from a plurality of said devices, said control device charges said power storage device using said power supply in accordance with a latest charging schedule out of said plurality of charging schedules.

9. The charging apparatus according to claim 8, wherein

said control device allows charging and discharging of said power storage device within a range where completion of the charging in accordance with said latest charging schedule is ensured.

10. The charging apparatus according to claim 8, wherein

said control device selects a last received charging schedule out of said plurality of charging schedules as said latest charging schedule.

11. The charging apparatus according to claim 8, wherein

said control device selects a last created charging schedule out of said plurality of charging schedules as said latest charging schedule.

12. The charging apparatus according to claim 8, wherein

said control device selects said charging schedule received from said vehicle when said latest charging schedule is unclear.

13. The charging apparatus according to claim 7, wherein

said charging apparatus is connected to said vehicle and an electrical device different from said vehicle, and

said control device performs the charging control on said power storage device in accordance with said charging schedule, and performs a process of managing supply and demand of electric power of said electrical device.

14. A charging system comprising:

a vehicle including a rotating electric machine and a power storage device for supplying electric power to said rotating electric machine;

a charging apparatus for charging said power storage device using a power supply outside of said vehicle;

a device for receiving information about a charging schedule of said power storage device from a user; and

a control device for notifying, when said charging schedule is created by input of said information to said device by said user, and when the charging schedule created based on a state of said vehicle and said charging schedule inputted do not match, a user of said vehicle that they do not match.

15. The charging system according to claim 14, wherein

when information about a plurality of charging schedules is received from a plurality of said devices, said control device charges said power storage device using said power supply in accordance with a latest charging schedule out of said plurality of charging schedules.
