Abstract

An electrically-driven vehicle includes: a battery; an induction motor connected to the battery; a synchronous motor connected to the battery that is connected to the induction motor; and at least one electronic control unit configured to change a slip frequency command of the induction motor based on a predetermined frequency of current fluctuation when a temperature of the battery is low such that an amplitude of the current fluctuation increases, the current fluctuation being any one of current fluctuation of a battery current or current fluctuation of a battery-related current that relates to the battery current.
