The global EV market is largely reliant on battery electric vehicles (BEVs) that employ lithium-ion (Li-ion) batteries, mostly based on liquid electrolytes. Due to extensive research and development of Li-ion, we are gradually reaching the maximum chemical potential of today’s electrode materials regarding Nickel-rich cathodes. Yet Li-ion based battery systems, based on liquid electrolytes, still face significant limitations , due to their chemistries, such as high flammability , potential safety risks, burning, and explosions, electrochemical instabilities, and low ion selectivity. In this regard, promising solutions are emerging in the form of solid-state battery EV (SSBEV) technology. However, the inherent differences between SSBs and traditional Li-ion batteries such as fundamentally distinct operating temperatures, charging rates, form factor and cell safety characteristics introduce complexities in integrating them into existing BEV systems, necessitating a redesign of the several systems. To meet this need, ARISE will develop an advanced solid-state, fourth generation (Gen-4) Li-ion battery system that offers advanced high-performance features, based on a cell-to-chassis concept with expandable modules that is applicable to any next generation S SBEV. ARISE will cover 3 different development paths: 1) a new city car chassis design utilizing SSBs that is expandable when needed, 2) a novel battery and pack level Thermal Management System compatible with SSBs, 3) Smart Battery Management System that controls battery expansion, fast charging, and safety.

HAVEN features a systematic, collaborative, and integrated approach to the design and demonstration of a cutting-edge, sustainable, and safe HESS capable of long duration storage and provision of multiple services for supporting the electrical grid and EV charging infrastructure by coupling complementary technology assets, namely, next-generation high-energy (HE) and high-power (HP) storage technologies, optimised power converter devices with innovative cognitive functionalities, advanced and cyber-secured energy management and control tools and strategies in a novel system architecture. HAVEN seeks to achieve a modular, scalable and cost-efficient solution with the capability to efficiently manage power and energy shares while optimising the system in terms of sizing, CAPEX/OPEX, aging stress and store degradation depending on the specific application. In addition, the project will go a step further by developing a flexible Digital Twin (DT) of the system, valid regardless of the cell chemistry and application and adaptable for second life battery modules, that enables to predict the performance and management of the system over its lifetime, while easing its design and predictive maintenance. All this, leveraged by the first-hand experience of leading academic and industrial players (7 companies). HAVEN’s smart solution will be validated and demonstrated up to TRL 7 in 3 physical and 2 virtual Use-Cases (UCs), covering a wide range of grid support services and considering the specificities of multiple electricity and balancing markets, both in Europe and beyond. To pave the path towards a fast market uptake after the project, the work will also include the development of business models and industrial exploitation strategies, cementing HAVEN’s position as a game-changer in the field of energy storage systems.
