The widespread use of electric vehicles is nowadays limited simply by the “range anxiety” associated with the customers. The drivers’ main concerns are related to the kilometric selection of the vehicle and to the charging time. An optimized fast-charge profile may help to decrease the charging time, without degrading the cell performance plus reducing the cycle lifetime. One of the major reasons for battery capability fade is linked to the Lithium plating sensation. This work investigates 2 methodologies, i. e., three-electrode cell measurement and internal resistance evolution during getting, for detecting the Lithium plating conditions. From this particular preliminary analysis, it was feasible to develop new Multi-Stage Constant-Current profiles, designed to enhance the performance in conditions of charging time plus cells capacity retention with respect to a research profile. Four new users were tested and in comparison to a reference. The results coming from the particular new profiles demonstrate the simultaneous improvement in conditions of charging time and cycling life, showing the particular reliability of the implemented methodology in preventing Lithium plating.
