Electric vehicle drivetrain: Sizing and validation using general and particular mission profiles

This paper presents the validation of the new European mission profiles on an electric vehicle simulator developed in the environment of AMESim (Advanced Modeling Environment for simulation). The electric vehicle drivetrain components are sized according to defined specifications and vehicle characteristics. A simplified control strategy is proposed in order to minimize the battery consumption. Taking into account the vehicle velocity, the acceleration and braking commands of the driver, optimal control laws are however provided by the control unit to the electric motor/generator and the braking system. Choosing a road and mission profiles, the validation is carried out for highway, road, urban, free urban and jam. Some particular cases are also studied in order to complete the study and to confirm the sizing of electric motor used in the propulsion chain. For each mission profile, the simulation results confirm the sizing of the drivetrain components. Also the performances are well reached using this proposed strategy control in the electric vehicle.
