Electrified vehicle includes a motor connected to the drive wheels, an inverter for driving the motor, a power storage device, a buck-boost converter for exchanging electric power between a low-voltage-side power line to which the power storage device is connected and a high-voltage-side power line to which the inverter is connected, an auxiliary device connected to the high-voltage-side power line, and a control device for controlling the inverter, the buck-boost converter, and the auxiliary device. The control device increases the power consumption of the auxiliary device as compared with the case where the predetermined condition is not satisfied when the predetermined condition is satisfied, in which the current flowing through the element of the buck-boost converter is in the direction of the low-voltage-side power line from the high-voltage-side power line and is larger than the threshold value.
