Abstract
An attempt is made to quantify the efficiency improvements in electric vehicles which can be obtained with optimized flux control. A constant current ratio control strategy and a true optimum flux control strategy are evaluated and compared in stationary speed-torque working points and for standard driving cycles. This is done by the use of a computer-assisting analysis program for electric vehicles. Two different systems are analyzed; a smaller vehicle with a DC motor drive, and a larger vehicle with an induction motor drive. The constant current ratio control strategy is shown to be a simple alternative to true optimum control for DC motors. Driving cycle calculations show efficiency improvements of up to 5-6% with optimized flux control.<>
