A method of cooling control for a drive motor of an electric vehicle is disclosed. The method includes controlling an output of a cooling apparatus for cooling the drive motor of the electric vehicle, using a navigation system to predict a deceleration followed by an acceleration in the driving speed of the electric vehicle, temporarily operating the cooling apparatus at a higher output to cool residual heat of the drive motor prior to beginning of the predicted deceleration, and temporarily operating the cooling apparatus at a higher output to cool the drive motor when the acceleration is predicted.

A method and a system for controlling motors is provided to have a vehicle travel smoothly in such a manner that, when a state of charge of a battery for supplying electric power stored to a plurality of motors included in the vehicle is low, a consumption of the battery is reduced by decreasing the electric power supplied to each motor of the plurality of motors. The method of controlling motors includes: determining a state of charge of a battery storing electric power supplied to each motor of a plurality of motors; calculating a present current consumption of each motor of the plurality of motors when the state of charge of the battery is equal to or less than a predetermined reference value; and resetting a power supply to each motor of the plurality of motors, based on the present current consumption of each motor of the plurality of motors.

An apparatus and method for controlling a cooling fan of a battery of a vehicle are provided. The apparatus includes a motor controller that drives a cooling fan motor of the battery based on information regarding control conditions of the cooling fan motor, and requests a backup process of a control of the cooling fan motor when an error in CAN communication by a CAN communicator or an error of the vehicle occurs. A backup processor then compensates for an output signal of the cooling fan based on at least one of an air conditioner pressure transducer (APT) output value, a vehicle speed, and a cooled water temperature and transmits the compensated output signal of the cooling fan to the motor controller.
