  "textContent": "A system for controlling an electric vehicle and method thereof are provided. The control method of electric vehicle includes operating a battery and a motor, detecting a torque command, a motor speed, and a motor current, calculating a motor voltage from the motor current, and determining when voltage utilization ,based on a speed range of the motor, is greater than a predetermined value. Further, the method includes generating an operating point correcting function, based on the motor speed, when the voltage utilization is less than the predetermined value and calculating a current command, according to the motor speed, from the operating point correcting function. Furthermore, the method also includes outputting the calculated current command.",
