In recent years, the transportation sector has witnessed a shift away from traditional combustion-based propulsion, driven by growing concerns over air pollution and climate change. Among the multitude of emerging technologies, battery electric vehicles (BEVs) have emerged as a prominent and highly supported solution. However, despite their increasing popularity, questions persist regarding their practical benefits in the current scenario. Challenging aspects are electric energy mix, battery longevity, and BEVs driving range. In this context, the following project aims to improve battery durability in BEVs. Then, to achieve this target, the main focus is on the Heating Ventilation and Air Conditioning (HVAC) unit, the most impacting auxiliary in terms of battery loads.
