This report examines alternative electric truck charging methods and outlines an R&D plan for next-generation high-power charging. It reviews various EVSE configurations and emerging technologies beyond standard plug-in systems, including automated conductive connections (overhead or vehicle-mounted pantographs, high-power pin-and-socket interfaces) and wireless inductive charging pads [etruc.org]. For each approach, it identifies technical gaps (e.g., lack of standards, hardware limitations) that must be addressed to achieve megawatt-scale charging [etruc.org]. The report also analyzes the impacts of ultra-fast charging on the electric grid, highlighting potential challenges in power delivery and load management as truck charging power reaches the megawatt level [etruc.org]. It concludes with prioritized R&D recommendations to advance these alternative charging solutions and ensure that future infrastructure can meet heavy-duty fleet needs.
