NEXT-generation physics and data-based Battery Management Systems for optimised battery utilization

The EU aims to become an economy with net-zero greenhouse gas emissions, achieving climate neutrality by 2050. Batteries will enable this clean energy transition by helping to decarbonise transport and enabling a higher uptake of renewable energy technologies. Therefore, the electrification of the European economy and society, both in transport and stationary storage sectors, has resulted in an expensive growth of the European battery industry (from battery cell manufacturers to recycling and second use companies). Achieving optimal utilisation of battery systems (by increasing the operational and lifetime usage window and reducing cost via a more efficient and appropriate use of materials) benefits not only the environment but also the end-users. The overall NEXTBMS aim is to develop an advanced battery management systems (BMS) built on fundamental knowledge and experience with the physicochemical processes of lithium-ion batteries, which will enable the significant enhance of current modelling approaches, including the readiness for upcoming lithium (Li) battery material developments. These modelling approaches will be further improved by optimising sensors and measurement techniques to meet modelling needs (and optimising models based on physical sensor data) and the physical cell configurations to form a framework that supports improving the battery state prediction and -control. By solving these challenges, NEXTBMS will ensure that the next generation of BMSs will enable higher performance, safety, and longer lifetime of the battery cells for an overall optimal utilisation of the battery system. As the NEXTBMS results aim to be implemented in a large variety of the transport and energy storage sectors, the project has a wide market potential to impact and revolutionize the entire battery market and to contribute in achieving the Green Deal objectives.
