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 configured to supply electric power to the rotating electric machine; and

an electronic control unit configured to set a charging schedule of the power storage device, the setting of the charging schedule by the electronic control unit including;

receiving information about a charging schedule of the power storage device inputted by a user at each of a plurality of devices and creating a plurality of charging schedules based on the corresponding information inputted at each of the plurality of devices,

receiving from the plurality of devices information related to input times of when the user inputted the corresponding information about the charging schedule at each of the input devices, and

selecting the charging schedule corresponding to the latest input time as a latest charging schedule, and charging the power storage device via an external power supply in accordance with the latest charging schedule.

2. The vehicle according to claim 1, wherein

the electronic control unit performs, when a time measured by at least one of the plurality of devices is incorrect, a process of correcting the time.

3. The vehicle according to claim 1, wherein

the electronic control unit is configured to create a second charging schedule based on the state of the vehicle,

the first and second charging schedules include information associated with a charging start time and a charging end time, and

when the charging end time of the first charging schedule and the charging end time of the second charging schedule do not match, the electronic control unit is configured to inquire the user on whether an update of the charging schedule is allowed.

4. A charging apparatus configured to perform charging control on a power storage device of a vehicle via a power supply outside of the vehicle, the vehicle including a rotating electric machine and the power storage device configured to supply electric power to the rotating electric machine, the charging apparatus comprising:

an input device configured to receive information about a charging schedule of the power storage device input by a user at each of a plurality of devices; and

an electronic control unit configured to;

receive information about a charging schedule of the power storage device from the input device and create a plurality of charging schedules based on the information inputted at each of the plurality of devices,

receive from the plurality of devices information related to input times of when the user inputted the corresponding information about the charging schedule at each of the input devices, and

select the charging schedule corresponding to the latest input time as a latest charging schedule, and charge the power storage device via an external power supply in accordance with the latest charging schedule.

5. The charging apparatus according to claim 4, wherein

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

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

6. The charging apparatus according to claim 4, wherein

the electronic control unit is configured to create a second charging schedule based on the state of the vehicle,

the first and second charging schedules include information associated with a charging start time and a charging end time, and

when the charging end time of the first charging schedule and the charging end time of the second charging schedule do not match, the electronic control unit is configured to inquire the user on whether an update of the charging schedule is allowed.

7. The charging apparatus according to claim 6, wherein

the electronic control unit charges the power storage device in accordance with the second charging schedule when the latest charging schedule is unclear.

8. A charging system comprising:

a vehicle including;

(i) a rotating electric machine, and (ii) a power storage device configured to supply electric power to the rotating electric machine;

a charging apparatus configured to charge the power storage device via a power supply located outside of the vehicle;

a plurality of input devices configured to receive information about a charging schedule of the power storage device from a user, and

an electronic control unit configured to;

receive the information about a charging schedule inputted by the user at each of the plurality of devices, and create a plurality of charging schedules based on the corresponding to the information inputted at each of the plurality of devices,

receive from the plurality of devices information related to input times of when the user inputted the corresponding information about the charging schedule at each of the input devices, and

select the charging schedule corresponding to the latest input time as a latest charging schedule, and charge the power storage device via an external power supply in accordance with the latest charging schedule.

9. The charging system according to claim 8, wherein

the electronic control unit is configured to create a second charging schedule based on the state of the vehicle,

the first and second charging schedules include information associated with a charging start time and a charging end time, and

when the charging end time of the first charging schedule and the charging end time of the second charging schedule do not match, the electronic control unit is configured to inquire the user on whether an update of the charging schedule is allowed.
