Summary:

Reducing greenhouse gas emissions to alleviate global warmingwill certainly be one of the major challenges of the 21st century.Transportation plays a very important part in this, which is whythe European Commission and the European manufacturers have foundan agreement to limit the average emissions of vehicles to 130gCO₂/km in 2012 and 95 gCO₂/km in 2020. Cutting vehicles'consumption of hydrocarbons is becoming a critical issue to reachthese ambitious targets. Electric vehicles, characterized by zerodirect CO₂ emissions, seem to be a relevant way to achieve theseCO₂ emissions.Despite their capabilities to emit no local pollution and tooperate silently, electric vehicles have also one importantdrawback: the limited autonomy offered to the customer. As forconventional vehicles, energy consumption for electric vehicles isvery dependant of driving conditions, such as driving cycles andambient temperature operating conditions for instance.Consequently, assessment of the electric vehicle autonomy can bevery dependant of assumptions taken into account during its design,which may be a real limitation to the use and deployment of thesetypes of vehicles.The objective of this paper is to present a global methodologyto design an electric vehicle and to evaluate the sensitivity ofthis sizing process to the assumptions and the requirements takeninto account. The presented methodology consists in transformingvehicle and customer requirements towards objectives andconstraints on the electric powertrain. Several types of vehiclerequirements and driving cycles are taken into account. A tool ableto design the electric machine and to evaluate its efficiency hasbeen used in this study. Finally, the design phase leads to a finalelectric powertrain adapted to the whole requirements whileoptimizing its global efficiency and its dimensions
