ESTRELIA - Energy Storage with lowered cost and improved Safety and Reliability for electrical vehicles
Overview
Background & policy context:
For a significant improvement of full electric vehicles’ (FEV) 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 concentrates on the value added-chain to guarantee a wide acceptance to the industry and attract the end-users, which are people of the European community. Only when it is possible to mitigate the constraints for the user of the FEVs will a wide acceptance and broad adoption 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.
Objectives:
Development objectives with the target to provide verified prototypes:
- develop an integrated flexible battery management system (BMS) for ultracapacitor cell balancing
- provide new ultracapacitor power cell pack design targeting for 50% higher energy density and verify enhanced reliability
- assess power pack in accordance with new standards and guidelines for robustness validation and lifetime cycle (ILCD)
- provide automotive environment verified prototypes for integrated flexible battery management system BMS for Li-Ion energy packs allowing simultaneous cell measurement and active Li-Ion battery cell balancing
- develop and characterize optimized and cost reduced BMS communication ICs with galvanic isolation up to 2.5kV
- target to reduce the electronic component costs for integrated Li-Ion battery management system BMS by 1/3rd
- provide new gas safety sensors with high sensitivity and fast response for advanced energy storage systems
- develop new high voltage (several kV) capable test and characterization equipment
Research objectives to evaluate further cost reduction and safety improvement potential:
- develop and evaluate new advanced MEMS based spark detection sensor to improve safety monitoring of energy storage systems
- verify new advanced Li-Ion BMS reliability and improved long-term stability
- investigate future BMS ICs technology integration and cost improvement potential
- develop new cost effective power antifuse for dynamical configuration of energy storage units
- Investigate gassensor hot plate and CMOS integration potential for cost reduction
Methodology:
ESTRELIA is defined in four phases to meet the targets of developing advanced new and cost effective building blocks to improve energy storage, reliability, safety and offer new battery management solutions for FEVs.
