Abstract

Electric Vehicles (EVs) will be in a near future a non-negligible part of the world's car fleet. Nevertheless, a dense network of Fast Charging Stations (FCS) on highways is needed to enable EVs to be competitive with Internal Combustion Engine (ICE) vehicles for long distances. FCS require high power from the grid to charge EVs in less than 30 minutes. Such high power will generate negative impacts on the power grid and will necessitate high investment costs for grid connection. A Battery Electric Storage System (BESS) inside the FCS could alleviate those negative impacts. The presence of a BESS then permits to offer grid services and to increase the profits of the FCS operator. However, the deployment of grid services with BESS is often faced to concerns on additional battery degradation. In this paper, we propose a FCS model including grid services and a study of battery degradation under different circumstances, and an economic comparison is done with the net present value.
