Abstract

A house-side ECU executes a program including the steps of, if a charging cable is being connected, if a vehicle can be externally charged by a reservation, and if there is reservation information by a user'"'"'s input in the vehicle, receiving the reservation information from the vehicle, and if there is reservation information based on a state of the vehicle in the vehicle, receiving the reservation information from the vehicle, selecting one of the reservation information, and making a notification of the reservation information.

Claims

1. A charging system comprising:

a first control device provided in a vehicle for controlling external charging of a power storage device mounted on said vehicle by a power supply outside of the vehicle; and

a second control device provided in a charging apparatus outside of said vehicle for controlling the external charging,

when a reservation for said external charging has been made in both said first control device and said second control device, said external charging being performed by giving the reservation in said second control device a higher priority than the reservation in said first control device.

2. The charging system according to claim 1, wherein

when a reservation for said external charging has been made in both said first control device and said second control device, and when the reservation in said first control device has been made at a request based on a state of said vehicle which is different from a request by a user, said external charging is performed by giving the reservation in said first control device a higher priority than the reservation in said second control device.

3. The charging system according to claim 1, wherein

when a reservation for said external charging has been made in both said first control device and said second control device, and when the reservation in said first control device has been made before communication between said first control device and said second control device becomes possible, said external charging is performed by giving the reservation in said first control device a higher priority than the reservation in said second control device.

4. The charging system according to claim 2, wherein

when the reservation in said first control device is given a higher priority, charging and discharging of said power storage device is allowable within a range where said external charging by the reservation in said first control device can be completed.

5. The charging system according to claim 1, wherein

at least one of said vehicle and said charging apparatus is provided with a notification device for making a notification of which one of the reservation in said first control device and the reservation in said second control device has been given a higher priority.

6. The charging system according to claim 1, wherein

when a reservation for said external charging has been made, said first control device cancels the reservation in said first control device while transmitting reservation information to said second control device when communication with said second control device becomes possible.

7. The charging system according to claim 6, wherein

said first control device generates said reservation information such that the reservation in said first control device can be distinguished between a reservation based on a request by a user and a reservation based on a state of said vehicle.

8. The charging system according to claim 1, wherein

said charging apparatus is part of an electric power management system for adjusting an amount of power used by at least one of a plurality of electrical devices connected to said power supply.

10. The charging system according to claim 3, wherein

when the reservation in said first control device is given a higher priority, charging and discharging of said power storage device is allowable within a range where said external charging by the reservation in said first control device can be completed.

9. A charging reservation method using a first control device provided in a vehicle for controlling external charging of a power storage device mounted on said vehicle by a power supply outside of the vehicle, and a second control device provided in a charging apparatus outside of said vehicle for controlling the external charging, comprising the steps of:

when a reservation for said external charging has been made in both said first control device and said second control device, selecting and giving a higher priority to the reservation in said second control device than the reservation in said first control device; and

performing said external charging in accordance with the selected reservation.
