An electric vehicle comprises an electric motor for driving a wheel; a main battery for activating the electric motor; a case to which a sub-battery for activating the electric motor is detachably mounted; a connection terminal to which a terminal of the sub-battery is connected; a mounting detecting sensor for detecting that the connection terminal is connected to the terminal of the sub-battery; and a controller which detects the SOCs of the batteries and is configured such that electric power is supplied preferentially from the mounted sub-battery to the electric motor, when the SOC of the sub-battery is equal to or greater than a predetermined value, and electric power is supplied from the main battery to the electric motor, when the SOC of the sub-battery is less than the predetermined value.
