With the increasing awareness on environmental issues, research and development revolving around automotive industry – one of the most important yet pollutant industries world-wide – has gained momentum. In recent years, electric vehicles (EVs) have been widely accepted as a clean and reliable alternative to fossil fuel vehicles, both in private and public transportation sectors, and are expected to quickly take over the market in the upcoming years. Lithium-ion batteries (LIBs) have emerged as the main enabling technology in the development of EVs, due to their high energy density and long lifespan. One of the key challenges posed by the spread of EV LIB packs is the real-time estimation of their state of health (SOH), commonly regarded as the main indicator of EV aging.
