About ESTRELIA

For a significant improvement of FEV’s safety and comfort as well as the improvement of the energy efficiency and extended driving range an innovative battery management and control solution is essential. Clearly, what is needed is a focused approach on the battery management system on the one hand but also the cost effective system integration into the vehicles on the other hand.

The ESTRELIA consortium fully concentrates therefore on the whole value added-chain to guarantee a wide acceptance to the industry and attract at the end of the day to the end-users which are people of the European community. Only when it is possible to mitigate the constraints for the user of the FEV’s a wide acceptance and broadadoption will be guaranteed of these new effective, innovative solutions for future mobility. The Consortium of this project has the full range of industry-leading capabilities to ensure a significant improvement of FEV in terms of performance, long term reliability, safety and comfort.
