​Background & Objectives
HiHELIOS aims to deliver a TRL 7 modular, scalable, circular-by-design and safe Hybrid Energy Storage System (HESS) that combines High-Power storage capabilities of LFP battery or supercapacitors, with High-Energy storage capabilities of second-life NMC batteries.
To achieve this, HiHELIOS will adapt the modular, flexible and scalable HESS architecture developed in the EU project SEABAT for marine applications at TRL 5-6, to grid applications and EV charging support.
Objectives
1
Development of a modular, flexible and scalable system architecture for hybrid battery topologies for stationary applications compatible with 1st and 2nd life battery types.
2
Development of a digital simulation framework (data-based and physics-based) for optimal hybrid battery system design and sizing for various grid applications including EV charging infrastructure support.
3
Development of an interoperable, scalable, robust, multi-layered and cyber-secured control system.
4
Optimization of physics-based and data-driven multi-chemistry models for real-time SOH diagnosis.
5
Model-supported HESS engineering and manufacturing and HESS demonstration at TRL 7.
6
Socio-techno-economic and LCA assessment, business case analysis and exploitation strategy.
