The electric vehicles are often associated to the range anxiety phenomenon. In the paper, this is tackled by the elaboration of a set of physics-based drivetrain models aiming to accurately estimate the energy consumption of a medium class vehicle. After a convincing validation of the model with respect to the VW ID.3 WLTP ratings, some usual driving scenarios are investigated to identify eco-driving tips to help the EV driver optimize the use of its vehicle. The results indicate that a compromise should be found between the aerodynamic drag and the electrical Joule effects. Additionally, few charging loss computations are performed and indicate that it represents between 6 and 12% of the total charging energy.

摘要

The electric vehicles are often associated to the range anxiety phenomenon. In the paper, this is tackled by the elaboration of a set of physics-based drivetrain models aiming to accurately estimate the energy consumption of a medium class vehicle. After a convincing validation of the model with respect to the VW ID.3 WLTP ratings, some usual driving scenarios are investigated to identify eco-driving tips to help the EV driver optimize the use of its vehicle. The results indicate that a compromise should be found between the aerodynamic drag and the electrical Joule effects. Additionally, few charging loss computations are performed and indicate that it represents between 6 and 12% of the total charging energy.
