Original Abstract Submitted

An electric vehicle includes: first and second rotating electric machines for driving front wheels and rear wheels; a battery for supplying power to the rotating electric machines; a cooling liquid circulating circuit for collecting heat from the rotating electric machines with cooling liquid and supplying heat to the battery; and an electronic control device for controlling driving of the rotating electric machines. Further, the first rotating electric machine is a winding field motor, and when a temperature of the battery is desired to be raised during traveling, the electronic control device flow current only through stator coil with respect to the first rotating electric machine, collect heat with cooling liquid, supply the collected heat to the battery to raise the temperature of the battery, and perform control of outputting a driving force required for travelling with the second rotating electric machine.
