CONTROL DEVICE AND CONTROL METHOD

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.
