Abstract

A control device for controlling a vehicle, wherein the vehicle includes a power storage device and a power converter. The power converter is configured to be capable of charging the power storage device using electric power from the outside of the vehicle, and discharging electric power from the power storage device to the outside of the vehicle. The control device includes a CPU and a memory that stores a process executed by the processor. CPU controls the power supply device so that the target SOC set by the user of the vehicle is reached at the scheduled departure time. CPU causes the power supply device to perform at least one of charge/discharge in a range higher than the lower limit SOC when the vehicle does not depart even after the scheduled departure time has elapsed.

First claim

What is claimed is:

1 . A control device that controls a vehicle, wherein:
the vehicle includes a power storage device and a power supply device; the power supply device is configured to allow at least one of charging of the power storage device using electric power from an outside of the vehicle and discharging of electric power from the power storage device to the outside of the vehicle; the control device includes a processor and a memory that stores a process to be executed by the processor; the processor controls the power supply device such that a target state of charge (SOC) set by a user of the vehicle is reached at a scheduled departure time; and the processor causes the power supply device to perform at least one of charging and discharging in a range higher than a lower limit SOC set by the user of the vehicle when the vehicle has not departed at the scheduled departure time.

2 . The control device according to claim 1 , wherein:
the power supply device is configured to allow at least one of charging of the power storage device using electric power from an electric power facility provided outside the vehicle, and discharging of electric power from the power storage device to the electric power facility; the electric power facility is connected to a facility that includes at least one electric power load; and when an electric power rate of electric power consumed by the electric power load is higher than an electric power rate of the electric power charged in the power storage device, the processor causes the power supply device to discharge electric power from the power storage device to the electric power facility.

3 . The control device according to claim 1 , wherein:
an electric power facility includes a power generation device that is able to generate electric power using renewable energy and that supplies electric power to an electric power load; and the control device causes the power supply device to charge the power storage device when it is determined that surplus power is generated in the power generation device.

4 . The control device according to claim 1 , wherein:
the vehicle further includes a relay provided in an electric circuit between the power supply device and the power storage device; and the processor turns on the relay at the scheduled departure time.

5 . The control device according to claim 4 , wherein the processor does not perform power utilization control in any of the following cases:
when a number of times of operation of the relay becomes equal to or greater than a predetermined number of times; when a degree of deterioration that indicates a state of deterioration of the power storage device becomes equal to or greater than a predetermined value; and when an integrated charge-discharge time of charging and discharging of the power supply device becomes equal to or greater than a predetermined value.
