Abstract

A vehicle includes an electric power storage device, a charging inlet, an electric power reception device, and a controller. The controller is configured to start charging the electric power storage device when the time reaches a set time set in advance in a case where scheduled charging control that starts charging the electric power storage device at the set time is planned to be executed in a state in which electric power is receivable through either the charging inlet or the electric power reception device. The controller is configured to execute the contacted charging control by suppressing execution of the scheduled charging control that starts the contactless charging control, when the charging connector is connected to the inlet in a case where the scheduled charging control that starts the contactless charging control at the set time is planned to be executed.

Claims

1. A vehicle comprising:

an electric power storage device;

a charging inlet configured to be connected to a charging connector disposed in a charging cable connected to an electric power supply outside the vehicle;

an electric power reception device configured to contactlessly receive electric power from the electric power supply; and

a controller configured to execute either contacted charging control to charge the electric power storage device using electric power received from the electric power supply through the charging inlet, or contactless charging control to charge the electric power storage device using electric power received from the electric power supply through the electric power reception device, wherein;

the controller is configured to start charging the electric power storage device when the time reaches a set time set in advance in a case where scheduled charging control that starts charging the electric power storage device at the set time is planned to be executed in a state in which electric power is receivable through either the charging inlet or the electric power reception device;

the scheduled charging control includes scheduled charging control that starts the contactless charging control, and scheduled charging control that starts the contacted charging control; and

the controller is configured to execute the contacted charging control by suppressing execution of the scheduled charging control that starts the contactless charging control, when the charging connector is connected to the charging inlet in a case where the scheduled charging control that starts the contactless charging control at the set time is planned to be executed.

2. The vehicle according to claim 1, wherein execution of the scheduled charging control that starts the contactless charging control is suppressed by canceling planned execution of the scheduled charging control.

3. The vehicle according to claim 1, wherein the controller is configured to suppress execution of the scheduled charging control that starts the contacted charging control, when an operation of disconnecting the charging connector and the charging inlet from each other, or an operation of connecting the charging connector to the charging inlet is performed in the case where the scheduled charging control that starts the contacted charging control at the set time is planned to be executed.

4. The vehicle according to claim 3, wherein execution of the scheduled charging control that starts the contacted charging control is suppressed by canceling planned execution of the scheduled charging control.

5. The vehicle according to claim 1, wherein:

the controller is configured to determine whether electric power is receivable through the electric power reception device, based on a positional relationship between the electric power reception device and an electric power transmission device configured to transmit electric power to the electric power reception device from the electric power supply outside the vehicle;

the controller is configured to start charging the electric power storage device by the contactless charging control when the time reaches the set time in a case where the scheduled charging control that starts the contactless charging control at the set time is planned to be executed in a state in which the controller determines that electric power is receivable through the electric power reception device; and

the controller is configured to stop the contactless charging control when the positional relationship between the electric power reception device and the electric power transmission device is changed to the positional relationship in which the contactless charging control is not executed, or when a state of charge of the electric power storage device reaches a threshold.

6. The vehicle according to claim 1, further comprising a connection detection circuit configured to detect whether the charging inlet is connected to the charging connector, wherein:

the controller is configured to determine whether the connection is made, based on a detection signal that is output from the connection detection circuit;

the controller is configured to start charging the electric power storage device by the contacted charging control when the time reaches the set time in a case where the scheduled charging control that starts the contacted charging control at the set time is planned to be executed in a state in which the controller determines that the contacted charging control is performed when the controller determines that the connection is made; and

the controller is configured to stop the contacted charging control when the charging connector is detached from the charging inlet, or when a state of charge of the electric power storage device reaches a threshold.
