By the end of the LIBERTY project, major technological progress was achieved in the design, integration, and validation of a high-voltage battery pack. Innovations included advanced thermal management, improved safety features, battery monitoring systems, and strategies for end-of-life and second-life use. These results led to the identification of key exploitable results (KERs) and were widely disseminated across industry and research through workshops, conferences, publications, exhibitions, and targeted communications.
The following summarize the main achievements of the project:
• Definition of design criteria, system requirements, and validation plan
• Battery and mechanical system design
• Electric, thermal, and mechanical cell-level testing and modelling
• Cell arrangement and immersion cooling system design and testing
• Active safety system development and simulations
• 800 V HV electrical subsystem development
• Solid-state main switch and low-power pressure sensor implementation
• BMS hardware demonstrators and SOC algorithm validation
• Development of aging test protocols, including fast-charging strategies
• Adaptation and testing of a Thermal Runaway simulator
