Thermal modelling and control of Li-ion batteries: Lithium-ion batteries are essential for clean energy storage, but their performance, safety, and lifespan depend on effective thermal management. If a battery gets too hot, it can degrade faster or, in extreme cases, enter into thermal runaway. On the other hand, cooling methods need to be efficient and […]

Our research addresses the growing challenge of safely recycling lithium-ion batteries (LIBs) amid increasing electric vehicle adoption. We introduce a novel methodology for real-time monitoring of both voltage and current during electrochemical discharge using NaCl solution. While traditional approaches rely solely on voltage measurements, our findings demonstrate that current measurement provides crucial additional insights into […]

Battery models in PyBaMM are widely used to predict performance, but identifying accurate model parameters is a significant challenge. Various parameter sets have been reported in literature [1,2,3], however, their consistency and reproducibility is lacking due to the need for specialist, costly equipment and extensive testing times, plus non-standardised procedures and lack of published data. […]
