International audience; The major priority of the carmakers is to reduce the energy consumption and the emissions of the future passenger cars and to deliver an efficient mobility service for the customers. The number of electrified vehicles increases in the mobility market. The range and the energy storage of the vehicle on board are important. The recharging of the vehicles and their connection to the energy grid became an important question. In this article, the energy system is extended and includes the energy storage and conversion of vehicles and their connection to the grid. The extended energy system is modelled on vehicles flows on the highway and a single objective optimization is performed to define the optimal energy storage capacity of the vehicles and the optimal number of recharges of from the grid. The time and the occupation rates of the chargers are as well evaluated. The optimality is researched for long way drives on electric mode. The results illustrate a method to rethink the usage and the energy management on the vehicle during the driving. As well it is researched how to adapt the recharging capacities and their location on the grid, by using a holistic approach. The target is to propose a high quality service for the electric mobility for long way drives.
