Abstract

A vehicle includes: a solar panel; a power storage device configured to store electric power generated by the solar panel; and a control device configured to control charging and discharging of thee power storage device such that a state of charge of the power storage device is in a range between an upper limit value and a lower limit value. The control device is configured to set the upper limit value to be larger when an external power supply mode in which the electric power generated by the solar panel is supplied to the outside of the vehicle via the power storage device is selected than when the external power supply mode is not selected.

Claims (22)

1. A vehicle comprising:

a solar panel;

a power storage device configured to store electric power generated by the solar panel; and

a control device configured to control charging and discharging of the power storage device such that a state of charge of the power storage device is in a range between an upper limit value and a lower limit value,

wherein the control device is configured to set the upper limit value to be larger when an external power supply mode in which the electric power generated by the solar panel is supplied to an outside of the vehicle via the power storage device is selected than the upper limit value when the external power supply mode is not selected.

2. The vehicle according to claim 1 , wherein

the power storage device includes a first power storage device and a second power storage device,

the first power storage device is configured to store electric power supplied from the second power storage device,

the first power storage device is configured to supply the electric power to the outside of the vehicle when the external power supply mode is selected,

the second power storage device is configured to store the electric power generated by the solar panel, and

the control device is configured to set the upper limit value of the state of charge of the second power storage device to be larger when the external power supply mode is selected than the upper limit value when the external power supply mode is not selected.

3. The vehicle according to claim 2 , wherein

the control device is configured to set a magnitude of at least one of a limiting value of charging power of the second power storage device and a limiting value of discharging power of the second power storage device to be larger when the external power supply mode is selected than when the external power supply mode is not selected.

4. The vehicle according to claim 2 , wherein

the control device is configured to set the lower limit value of the state of charge of the second power storage device to be smaller when the external power supply mode is selected than the lower limit value when the external power supply mode is not selected.

5. The vehicle according to claim 1 , wherein

the control device is configured to select the external power supply mode when selection of the external power supply mode is required by a user.

6. The vehicle according to claim 1 , further comprising

a communication device configured to communicate with a communication target outside the vehicle, wherein

the control device is configured to select the external power supply mode when a predetermined signal from the outside of the vehicle is received by the communication device.

7. The vehicle according to claim 4 , wherein

the control device is configured to charge the first power storage device with the electric power of the second power storage device until the state of charge of the second power storage device reaches the lower limit value when the state of charge of the second power storage device has reached the upper limit value.
