Fig. 4: Carbon footprint and energy consumption of E-Trucks under different operations with different delay factors.
From: Optimizing carbon footprint in long-haul heavy-duty E-Truck transportation
A larger delay factor means a more relaxed deadline. The results are for the distance category of 500–1000 miles. The results for all four distance categories can be found at Supplementary Fig. 7 in Supplementary Information Section 6.2. a The normalized carbon footprint with respect to ICE trucks under today’s common practice. b The normalized energy consumption with respect to ICE trucks under common practice. In both (a, b), box plots show interquartile ranges (25th–75th percentiles) with median values indicated by internal lines. Square markers denote mean values, and error bars represent  ±1.5 standard deviations. Source data of this figure are provided in the Source Data file.
