In this book, we describe a methodology of systemic design of electric vehicles (EVs) power chain, reducing the cost and the consumption. This methodology rests on the choice of the structure and the components of this chain reducing jointly the cost and the consumption of EVs. Indeed, a synchronous motor structure to permanent magnets and axial flux reducing the production cost that can presented under several configurations is defined and restraint in relation to the equivalent structure with coiled rotor or to double excitation. The choice of the static converter oriented toward a structure to two levels voltage and to electromagnetic switches is in the goal to increase the reliability of the global system and to push the multiple inconveniences of the IGBTs. The adaptation of this low-frequency converter structure is assured by insertion of a speed amplifier to gearing. Finally, the modelling under the environment of Matlab/Simulink of the power chain integrating a system of energy recuperation and a system of minimization of the consumption by stacking of three modules on the axis of the motor during the phases of strong acceleration, validate this approach of design.
