Abstract:Class-8 battery electric trucks (BETs) were modeled and simulated in this project to determine their capability in fulfilling real-world drayage activity under different operational scenarios. Two different cases were developed and studied: (a) inductive or wireless charging at port terminals, and (b) wireless charging at loading/unloading stops. For port terminals, potential wireless charging zones were identified, and wireless charging opportunities were introduced to improve drayage activity fulfillment of BETs. The results showed that current BETs could fulfill approximately 79–86 percent of the real-world drayage activity sample used in this research and that their ability to receive wireless opportunity charging at port terminals could help increase the activity fulfillment to about 84–91 percent. For loading/unloading stops, energy gains from wireless charging for two trucks with 50 and 150 kW charging powers were studied. The results from this case study showed that one of these trucks needed opportunity charging at the home base once for the studied two-day period. The other truck needed additional opportunity charging at stops and would have benefitted from tour rescheduling to allow an extension of the stop duration to increase the charging duration.
