iFEMA - Integral Research Energy for Electromobility: From Model to Application

Electric vehicles are an essential part of the energy systems of the future. Therefore, they should be efficient and sustainable – both when they are on the road and when they are being charged.

In order to make the energy supply for electric mobility sustainable, efficient and secure, the iFEMA project combines all relevant scales for electric vehicles: the distribution grid with renewable generation plants, the charging station in the local energy system (microgrid), the vehicle's on-board network and the battery storage system. This is intended to resolve inherent conflicting goals between grid serviceability and fast charging, between bidirectional charging and battery lifetime, between climate friendliness and user requirements, between overall efficiency and partial efficiencies.

On the one hand, a digital twin of the overall system is being built for this purpose, with which optimal energy management is being developed. Various methods are used for this – from machine learning to physical-chemical models. On the other hand, an experimental twin is being set up to enable full scale coupling in a controlled laboratory environment.
