Abstract
An ECU of an electric vehicle supplies a target rotation speed RT having a value corresponding to the temperature TB of a main battery to a cooler, controls a main DC/DC converter such that the SOC of an auxiliary battery is in a predetermined range SOCL to SOCH less than 100% when a cooling fan in the cooler is driven at the target rotation speed (RT), and controls the main DC/DC converter such that the SOC of the auxiliary battery is 100% when the cooling fan is not driven at the target rotation speed (RT).
