Abstract

A vehicle includes a battery, an electric power acquirer, a power supply unit, first and second relays, and a controller. The electric power acquirer acquires charging electric power from outside. The power supply unit is able to provide a power supply from the battery to a device other than a traveling motor. The first relay connects and disconnects the battery to and from a power supply line. The second relay connects and disconnects the electric power acquirer to and from the power supply line. The controller changes a switching procedure of the first relay and the second relay, in accordance with a state of use of the power supply unit, at an end of charging of the battery through the electric power acquirer.

First claim

1 . A vehicle, comprising:
a battery configured to accumulate electric power for travel of the vehicle; an electric power acquirer configured to acquire charging electric power from outside; a power supply unit able to provide a power supply from the battery to a device other than a traveling motor; a first relay configured to connect the battery to a power supply line or to disconnect the battery from the power supply line; a second relay configured to connect the electric power acquirer to the power supply line or to disconnect the electric power acquirer from the power supply line; and a controller configured to change a switching procedure of the first relay and the second relay, in accordance with a state of use of the power supply unit, at an end of charging of the battery through the electric power acquirer.

2 . The vehicle according to claim 1 , wherein at the end of the charging, the controller
continues a connected state of the first relay on a condition that the power supply unit is in use, and switches the first relay to a disconnected state on a condition that the power supply unit is out of use.

3 . The vehicle according to claim 1 , wherein the power supply unit includes:
a prioritized power supply subunit set as a prioritized power supply; and an unprioritized power supply subunit set as a power supply having lower priority than the prioritized power supply subunit, and at the end of the charging, the controller further changes the switching procedure of the first relay and the second relay, on a basis of a state of use of the prioritized power supply subunit.

4 . The vehicle according to claim 2 , wherein the power supply unit includes:
a prioritized power supply subunit set as a prioritized power supply; and an unprioritized power supply subunit set as a power supply having lower priority than the prioritized power supply subunit, and at the end of the charging, the controller further changes the switching procedure of the first relay and the second relay, on a basis of a state of use of the prioritized power supply subunit.

5 . The vehicle according to claim 3 , wherein at the end of charging, the controller
continues a connected state of the second relay on a condition that the prioritized power supply subunit is in use, and switches the second relay to a disconnected state on a condition that the prioritized power supply subunit is out of use.

6 . The vehicle according to claim 4 , wherein at the end of charging, the controller
continues a connected state of the second relay on a condition that the prioritized power supply subunit is in use, and switches the second relay to a disconnected state on a condition that the prioritized power supply subunit is out of use.

7 . The vehicle according to claim 3 , further comprising a determination unit configured to determine possibility of use of the prioritized power supply subunit,
wherein at the end of the charging, the controller
continues a connected state of the second relay on a condition that the determination unit determines presence of the possibility of use of the prioritized power supply subunit, and
switches the second relay to a disconnected state on a condition that the determination unit determines absence of the possibility of use of the prioritized power supply subunit.

8 . The vehicle according to claim 4 , further comprising a determination unit configured to determine possibility of use of the prioritized power supply subunit,
wherein at the end of the charging, the controller
continues a connected state of the second relay on a condition that the determination unit determines presence of the possibility of use of the prioritized power supply subunit, and
switches the second relay to a disconnected state on a condition that the determination unit determines absence of the possibility of use of the prioritized power supply subunit.

9 . The vehicle according to claim 5 , further comprising a determination unit configured to determine possibility of use of the prioritized power supply subunit,
wherein at the end of the charging, the controller
continues a connected state of the second relay on a condition that the determination unit determines presence of the possibility of use of the prioritized power supply subunit, and
switches the second relay to a disconnected state on a condition that the determination unit determines absence of the possibility of use of the prioritized power supply subunit.

10 . The vehicle according to claim 6 , further comprising a determination unit configured to determine possibility of use of the prioritized power supply subunit,
wherein at the end of the charging, the controller
continues a connected state of the second relay on a condition that the determination unit determines presence of the possibility of use of the prioritized power supply subunit, and
switches the second relay to a disconnected state on a condition that the determination unit determines absence of the possibility of use of the prioritized power supply subunit.
