In recent years, the European Commission has imposed more stringent regulations on CO2 emissions, requiring significant reductions for Heavy-Duty Vehicles (HDV). For this reason, Battery Electric Trucks (BETs) are becoming a promising solution. While in urban delivery missions the limitations related to payload reduction due to battery weight and restricted driving range are relatively contained, their adoption for long-haul transport remains constrained by long charging times and significant payload penalties. These challenges have driven research into new technologies that allow recharging while driving: the Electrified Road System (ERS). This thesis evaluates the technical and sustainable feasibility, both environmental and economic, of Dynamic Wireless Power Transfer (DWPT) ERS to address the challenges of long-haul battery electric heavy-duty trucks (BEHDT) along a 715 km route between Torrazza (Piedmont) and Colleferro (Lazio).
