Abstract
An ECU included in a vehicle performs a first charging control when a minimum output voltage of a direct-current (DC) charger obtained through an information exchange process is less than or equal to a lower limit charging voltage for a power storage device, and performs a second charging control when the minimum output voltage is higher than the lower limit charging voltage of the power storage device. In the second charging control, initially, the ECU electrically connects a pre-charge circuit to a charging path from the DC charger to the power storage device, starts DC charging, and checks a voltage that is actually applied from the DC charger to the vehicle. If a voltage applied from the DC charger to the vehicle is a value corresponding to the voltage of the power storage device, the ECU permits the DC charging and performs the first charging control.
