Driving Range Evolution of an EV Regarding Cumulated Hours of Operation

This study deals with the driving range evolution of an EV as a function of the cumulated hours of operations. The studied vehicle is a three-wheel electric vehicle (e-TESC 3W platform) developed and instrumented at the University of Sherbrooke. The system model is built and organized using the Energetic Macroscopic Representation. A current cycle is applied with a programmable source on one cell to emulate the driving current constraints. The cell model parameters are characterized periodically. Then, the EV simulation is performed with the battery parameters corresponding to different cumulated driving hours. It is shown that the driving ranges is reduced by about 12% after 200 h of operations.
