AI-based methodology for estimating the remaining useful life (RUL) of second-life lithium-ion cells coming from EVs, to be reused in stationary ESS
This project aims to develop an AI-based methodology for the accelerated and accurate estimation of RUL in second-life lithium-ion cells. By using data-driven approaches, we intend to significantly reduce the time and cost of qualification processes and improve the efficiency of cell sorting and matching. Additionally, the project will explore modular ESS architectures with swappable cell units, enhancing the adaptability of second-life systems and maximizing the utility of available battery inventories.
The core of the solution will be machine learning models trained on operational and diagnostic data from used EV battery cells. These models will learn to identify patterns linked to degradation and performance decline, enabling precise RUL predictions without the need for long-term cycling tests. The approach will prioritize explainability and integration potential, so that outputs can support both automated decision-making and expert validation during repurposing. Over time, the system will improve its accuracy as more data becomes available from real-world deployments.

Brief description of my Organisation
Łukasiewicz – Automotive Industry Institute (PIMOT) is a part of the Łukasiewicz Research Network, one of the largest networks of its kind in the EU. The Institute's mission is to support the economy in the development and testing of new automotive technologies, as well as in the conformity assessment of automotive products with regulatory requirements. A team of 90 scientists and engineers takes on the most demanding technical challenges. Thanks to its modern infrastructure, the Institute offers comprehensive automotive research and testing, carried out in laboratories and research groups. The Institute's strong research potential has resulted in 250 patents and the completion of 100 projects over the past 20 years
