ABOUT THE PROJECT

NEXT GENERATION TECHNOLOGIES FOR BATTERY SYSTEMS IN TRANSPORT ELECTRIFICATION

The battery system project

NEXTBAT aims to develop the safest, most sustainable battery system by considering electrical, thermal, and mechanical safety. This effort includes digitalizing production, reducing the carbon footprint through recyclability, and enhancing performance with advanced battery management.

NEXTBAT develops next-generation battery systems using beyond state of cells as well as novel architectures when it comes to module and pack designs including advanced sensing, cooling (liquid and immersion), Battery Management Systems (BMS) and safety measures by using a design by safe principles.

The project also introduces innovative materials and processes to improve performance, safety, and recyclability, while working towards new industry standards for the European battery sector.

CHALLENGES

DIGITALISATION AND MODELLING FOR BATTERY SYSTEM DESIGN, MANUFACTURING AND RECYCLABILITY

The core of any laser-based process is undoubtedly the beam source itself. The beam source with the connected optical system consisting of collimation, deflection unit and focusing optics determine in many ways the caustics of the resulting laser beam, which is responsible for the energy transfer into the matter. Depending on the absorbed energy and the intensity of the laser beam at the matter surface, the laser-based process can be divided into joining or separation. The joining is melt-based process which consist of a three-part time sequence: melt formation, melt manipulation and final solidification.

DEMONSTRATION AND VALIDATION OF PROTOTYPED INNOVATIONS FOR TRANSPORT AND MOBILE APPLICATIONS

The experimental test matrix and content of the validation tests (electrical, thermal, safety) are defined within the project. The two prototypes will be tested to demonstrate their performances and to ensure that the safety features work properly. Tests will be conducted at different stage of prototype manufacturing process: a stepby-step approach will be followed to test the different sub-systems while assembling the prototypes.

CREATING IMPACT IN THE ELECTRIFICATION OF TRANSPORT AND MOBILE APPLICATIONS IN THE EU

Drawing on the technology implementation and testing/validation actions, NEXTBAT will promote a set of activities aimed at maximizing the future replication and impact of the project’s results.

The future of renewable energy lies in green storage

How are we going to do it

In the project, two prototypes will be developed. The first prototype aims to enhance energy density in battery designs, while the second focuses on increasing power density. NEXTBAT’s goal is to analyze, integrate design features, and align them with diverse application requirements. Additionally, certified laboratories and end-users will conduct testing campaigns to establish safety guidelines and methodologies. The assessment of dismantling and reusing Battery Management System (BMS) parts will be conducted in parallel with life cycle analysis.
