VEHICLE AND VEHICLE CONTROL METHOD

A vehicle includes: a PCU cooling system; a PCU that is cooled by the PCU cooling system; a buck converter; an auxiliary battery that is charged through a buck operation of the buck converter; and an ECU that outputs a first target voltage and a second target voltage respectively to the buck converters. The buck converter is disposed inside the PCU, performs a buck operation so that a target voltage is generated, and outputs a stepped-down electric power to a power line. The buck converter is disposed outside the PCU, performs a buck operation so that a target voltage is generated, and outputs a stepped-down electric power to the power line. The ECU sets the target voltage higher than the target voltage when the ECU causes PCU to operate.
