A Framework to Analyze the Requirements of a Multiport Megawatt-Level Charging Station for Heavy-Duty Electric Vehicles

Partha Mishra, Eric Miller, Shriram Santhanagopalan, Kevin Bennion, Andrew Meintz
2022 Energies  
This framework integrates an agent-based charging station model with vehicle schedules obtained through real-world vehicle telemetry data analysis to explore the station design and operation space.  ...  The results show a direct correlation between optimal charging station placement and major traffic corridors such as cities with ports, e.g., Los Angeles and Oakland.  ...  As charging opportunities increase, regional and long-haul trucks are electrified.  ...

Load and Unload Technology to Improve Round-Bale Hauling Efficiency

John S. Cundiff, Robert D. Grisso
2021 AgriEngineering  
Uncoupling the loading and hauling in this manner reduces the time the truck waits for loading and the SSL load-out waits for a truck; thus, productivity of both operations is increased.  ...  There are two key parameters in short-haul truck operations to deliver biomass to a biorefinery: (1) mass of the load and (2) cycle time (load, travel, unload, and return).  ...  The tractor-trailer truck used for the hauling has a trailer that can tilt, and a drive track that engages the ground and pulls the truck back under the 36-bale block to load it [6] .  ...
