Heavy-Duty Truck Electrification and the Impacts of Depot Charging on Electricity Distribution Systems

Published in Nature Energy, this study examines the grid integration challenges and opportunities for heavy-duty truck electrification, focusing on depot-based charging scenarios. Researchers analyzed real-world operating data to develop synthetic depot charging load profiles and assessed impacts on electricity distribution systems using 36 real-world substations. The study found that approximately 80% of examined substations could accommodate 100 trucks charging at 100 kW per vehicle without upgrades, with an additional 10% able to avoid upgrades through smart charging. The research demonstrates that short-haul heavy-duty operations (?200 miles) are prime candidates for electrification given their predictable routes and return-to-base applications.
