Theautomotive industry is currently undergoing a significant transition from non-renewable energy sources, primarily fossil fuels derived from crude oil, towards more sustainable al ternatives such as fuel cells, synthetic fuels, and electric power. Among these, electric energy is playing a central role, with BEVs and HEVs emerging as the most widespread solutions for passenger transportation. Despite their increasing market penetration over the past decade, these technologies still face several challenges that hinder full consumer acceptance, particularly when compared to traditional Internal Combustion Engine (ICE) vehicles. One of the primary limitations remains the reduced driving range. In this context, the research work focuses on enhancing battery systems to align with the performance expectations of modern users.
