Abstract

A house ECU executes a program when it is the time to set a scheduled time, including the step of transmitting an end time of external charging to a vehicle in the case where the end time has been input by a user, and the step of determining a start time in the case where the house ECU has received a required charging time from a vehicle ECU. The vehicle ECU executes a program when it is the time to set a scheduled time, including the step of calculating the required charging time in the case where the vehicle ECU has received the end time from the house ECU, and the step of transmitting the required charging time.

Claims

1. A charging system comprising:

a vehicle including a power storage device for supplying electric power to an electric motor serving as a driving source, and a first control device for controlling charging of said power storage device; and

a charging device including a power supply provided outside said vehicle, and a second control device for controlling external charging of said power storage device by means of said power supply, wherein

in a case where an end time of said external charging is input to said second control device, said second control device transmits said input end time to said first control device, and

in a case where said first control device receives said end time from said second control device, said first control device calculates a required charging time which is required for said external charging.

2. The charging system according to claim 1, wherein

said first control device transmits said calculated required charging time to said second control device, and

said second control device determines a start time of said external charging based on said end time and said required charging time received from said first control device, and starts said external charging at said determined start time.

3. The charging system according to claim 1, wherein

said first control device transmits said calculated required charging time to said second control device, and

said second control device performs a process for managing supply and receipt of electric power for an electrical device connected to said power supply, based on said end time and said required charging time received from said first control device.

4. The charging system according to claim 1, wherein

said first control device determines a start time of said external charging based on said end time and said calculated required charging time.

5. The charging system according to claim 1, wherein

said first control device calculates said required charging time based on at least one of a remaining capacity of said power storage device, an upper limit of charging power that can be supplied from said charging device to said power storage device, an upper limit of charging power that can be received by said power storage device, and a full charging capacity of said power storage device.

6. The charging system according to claim 1, wherein

said second control device determines said end time based on a scheduled departure time of said vehicle that is input by a user.

7. The charging system according to claim 1, wherein

said charging device is a part of a power management system for adjusting power consumption of at least one of a plurality of electrical devices connected to said power supply.

8. A charging scheduling method using a charging system comprising:

a vehicle including a power storage device for supplying electric power to an electric motor serving as a driving source and a first control device for controlling charging of said power storage device; and

a charging device including a power supply provided outside said vehicle and a second control device for controlling external charging of said power storage device by means of said power supply,

said method comprising the steps of;

transmitting by said second control device, in a case where an end time of said external charging is input to said second control device, said input end time to said first control device; and

calculating by said first control device, in a case where said first control device receives said end time from said second control device, a required charging time which is required for said external charging.
