Abstract:The production of electric cars in large series is still hampered by their low autonomy due mainly to the low energy storage capacity of the batteries and the importance of overall losses of the power chain. Indeed, the electric vehicle monitoring strategy is a key factor in energy savings leading to improved of the autonomy. In this paper, we present a systemic control methodology of a synchronous motor with axial flux dedicated to electric traction, taking into account several constraints such as speed limit, the cost of the traction chain losses of the various components of the electric vehicle and the system reliability.
