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.

To ensure that the energy supply for electric mobility is 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 vs. fast charging, bidirectional charging vs. battery lifetime, climate friendliness vs. user requirements, or overall vs. partial efficiencies.

On the one hand, a digital twin of the overall system is 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 set up to enable full scale coupling in a controlled laboratory environment.
