The invention provides a motor control system of an electric vehicle and the electric vehicle. A motor control system for an electric vehicle includes a battery, a motor having a rotor and a stator, two inverter circuits connected to the stator and respectively controlling driving and regeneration of the motor, and a control device controlling driving of the two inverter circuits. The motor control system includes a cooling water circuit circulating at least through the battery and the motor. The control device drives the cooling water pump to circulate the cooling water, drives the two inverter circuits to apply rotational torques in opposite directions to the rotor, and preheats the battery with the cooling water that is heated by heat generated by the motor.
