Abstract

A control device that is mounted on a vehicle including a power storage device, the control device includes a processor. The processor is configured to, when external charging and update of software used in the vehicle are executed in parallel, reduce charging power in the external charging such that a predicted update time needed for the update of the software is less than a predicted charging time needed for the external charging in a case where a time condition is satisfied in which the predicted update time is equal to or longer than the predicted charging time, the external charging being charging of the power storage device using power from an external power source that is provided outside of the vehicle.

First claim

What is claimed is:

1. A control device that is mounted on a vehicle including a power storage device, the control device comprising
a processor configured to, when external charging and update of software used in the vehicle are executed in parallel, reduce charging power in the external charging such that a predicted update time needed for the update of the software is less than a predicted charging time needed for the external charging in a case where a time condition is satisfied in which the predicted update time is equal to or longer than the predicted charging time, the external charging being charging of the power storage device using power from an external power source that is provided outside of the vehicle.

2. The control device according to claim 1 , wherein:
the vehicle further includes a second power storage device having a rated voltage lower than a rated voltage of the power storage device and a converter configured to step down power of a first power line to which the power storage device is connected and to supply the power to a second power line to which the second power storage device is connected; and
the processor is configured to, in the case where the time condition is satisfied when the external charging and the update of the software are executed in parallel, set the charging power in the external charging to predetermined power and to raise a target charging level of the second power storage device in a case where the predicted update time is not less than the predicted charging time within a range in which the charging power in the external charging is equal to or greater than the predetermined power.

3. The control device according to claim 1 , wherein the processor is configured to, when the external charging and the update of the software are executed in parallel, not reduce the charging power in the external charging in a case where the time condition is satisfied when the external charging is automatically restartable after being temporarily terminated.

4. A control method of a vehicle including a power storage device, the control method comprising:
executing, by a processor, external charging and update of software used in the vehicle in parallel, the external charging being charging of the power storage device using power from an external power source that is provided outside of the vehicle; and
reducing, by the processor, charging power in the external charging such that a predicted update time needed for the update of the software is less than a predicted charging time needed for the external charging when external charging and update of software used in the vehicle are executed in parallel and a time condition is satisfied in which the predicted update time is equal to or longer than the predicted charging time.
