Abstract
A vehicle includes: a power storage device configured to be charged using a power supply facility external to a vehicle; a communication device configured to obtain information indicating a user location Pu, from a user terminal carried by a user; and a vehicle ECU. In a charging standby state for the charging of the power storage device using the power supply facility, the vehicle ECU calculates a user traveling speed Vu and a user distance Du using user location Pu, and calculates a traveling time Tu required for the user to arrive at the vehicle using user traveling speed Vu and user distance Du. The vehicle ECU starts the charging of the power storage device when a value obtained by subtracting (i) a charging time Tc required to complete the charging of the power storage device from (ii) traveling time Tu becomes less than a predetermined value.
