摘要： 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.

摘要： 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.

摘要： 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.
