SYSTEMIC DESIGN OF ELECTRIC VEHICLES POWER CHAIN OPTIMIZING THE AUTONOMY

Abstract

A computer tool permitting to solve the design problem of the motorization chain maximizing the autonomy is developed. This tool rests on the modelling of the power chain taking account of the interactions that exists between the design and the control. A descriptive model of the behavior of the vehicle is developed and is coupled to the average model of the autonomy has permitted to fix the parameters that influence the middle autonomy on a mission of circulation, what drove to a dynamic optimization problem to several variable and constrained. This problem solved by the method of genetic algorithms drove to encouraging results. The vehicle conceived around an optimal autonomy on a mission of circulation and using a motor to permanent magnets to axial flux to weak cost of manufacture, present an interesting solution thus encourage their production in big set.
